<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b><i>TIFFGetField</i></b>
returns the value of a tag or pseudo-tag associated with the
the current directory of the opened <small>TIFF</small> file
<i>tif</i>. (A <i>pseudo-tag</i> is a parameter that is used
to control the operation of the <small>TIFF</small> library
but whose value is not read or written to the underlying
file.) The file must have been previously opened with
<i>TIFFOpen</i>(3TIFF). The tag is identified by <i>tag</i>,
one of the values defined in the include file <b>tiff.h</b>
(see also the table below). The type and number of values
returned is dependent on the tag being requested. The
programming interface uses a variable argument list as
prescribed by the <i>stdarg</i>(3) interface. The returned
values should only be interpreted if <i>TIFFGetField</i>
returns 1.</p>
<p style="margin-left:11%; margin-top: 1em"><i>TIFFVGetField</i>
is functionally equivalent to <i>TIFFGetField</i> except
that it takes a pointer to a variable argument list.
<i>TIFFVGetField</i> is useful for layering interfaces on
top of the functionality provided by
<i>TIFFGetField</i>.</p>
<p style="margin-left:11%; margin-top: 1em"><i>TIFFGetFieldDefaulted</i>
and <i>TIFFVGetFieldDefaulted</i> are identical to
<i>TIFFGetField</i> and <i>TIFFVGetField</i>, except that if
a tag is not defined in the current directory and it has a
default value, then the default value is returned.</p>
<p style="margin-left:11%; margin-top: 1em">The tags
understood by <i>libtiff(3TIFF),</i> the number of parameter
values, and the types for the returned values are shown
below. The data types are specified as in C and correspond
to the types used to specify tag values to
<i>TIFFSetField</i>(3TIFF). Remember that
<i>TIFFGetField</i> returns parameter values, so all the
listed data types are pointers to storage where values
should be returned. Consult the <small>TIFF</small>
specification (or relevant industry specification) for
information on the meaning of each tag and their possible
values.</p>

<p><i>TIFFOpen</i> opens a <small>TIFF</small> file whose
name is <i>filename</i> and returns a handle to be used in
subsequent calls to routines in <i>libtiff</i>. If the open
operation fails, then zero is returned. The <i>mode</i>
parameter specifies if the file is to be opened for reading
(‘‘r’’), writing
(‘‘w’’), or appending
(‘‘a’’) and, optionally, whether to
override certain default aspects of library operation (see
below). When a file is opened for appending, existing data
will not be touched; instead new data will be written as
additional subfiles. If an existing file is opened for
writing, all previous data is overwritten.</p>
<!-- INDENTATION -->
<p>If a file is opened for reading, the first
<small>TIFF</small> directory in the file is automatically
read (also see <i>TIFFSetDirectory</i>(3TIFF) for reading
directories other than the first). If a file is opened for
writing or appending, a default directory is automatically
created for writing subsequent data. This directory has all
the default values specified in <small>TIFF</small> Revision
6.0: <i>BitsPerSample</i>=1, <i>ThreshHolding</i>=bilevel
art scan, <i>FillOrder</i>=1 (most significant bit of each
data byte is filled first), <i>Orientation</i>=1 (the 0th
row represents the visual top of the image, and the 0th
column represents the visual left hand side),
<i>SamplesPerPixel</i>=1, <i>RowsPerStrip</i>=infinity,
<i>ResolutionUnit</i>=2 (inches), and <i>Compression</i>=1
(no compression). To alter these values, or to define values
for additional fields, <i>TIFFSetField</i>(3TIFF) must be
used.</p>
<!-- INDENTATION -->
<p><i>TIFFFdOpen</i> is like <i>TIFFOpen</i> except that it
opens a <small>TIFF</small> file given an open file
descriptor <i>fd</i>. The file’s name and mode must
reflect that of the open descriptor. The object associated
with the file descriptor <b>must support random
access</b>.</p>
<!-- INDENTATION -->
<p><i>TIFFClientOpen</i> is like <i>TIFFOpen</i> except that
the caller supplies a collection of functions that the
library will use to do <small>UNIX</small> -like I/O
operations. The <i>readproc</i> and <i>writeproc</i> are
called to read and write data at the current file position.
<i>seekproc</i> is called to change the current file
position a la <i>lseek</i>(2). <i>closeproc</i> is invoked
to release any resources associated with an open file.
<i>sizeproc</i> is invoked to obtain the size in bytes of a
file. <i>mapproc</i> and <i>unmapproc</i> are called to map
and unmap a file’s contents in memory; c.f.
<i>mmap</i>(2) and <i>munmap</i>(2). The <i>clientdata</i>
parameter is an opaque ‘‘handle’’
passed to the client-specified routines passed as parameters
to <i>TIFFClientOpen</i>.</p>

Strip chopping is a mechanism by which the library will
automatically convert the single-strip image to multiple
strips, each of which has about 8 Kilobytes of data. This
facility can be useful in reducing the amount of memory used
to read an image because the library normally reads each
strip in its entirety. Strip chopping does however alter the
apparent contents of the image because when an image is
divided into multiple strips it looks as though the
underlying file contains multiple separate strips. Finally,
note that default handling of strip chopping is a
compile-time configuration parameter. The default behaviour,
for backwards compatibility, is to enable strip
chopping.</p>

<p>The <small>TIFF</small> specification (<b>all
versions</b>) states that compliant readers <i>must be
capable of reading images written in either byte order</i>.
Nonetheless some software that claims to support the reading
of <small>TIFF</small> images is incapable of reading images
in anything but the native <small>CPU</small> byte order on
which the software was written. (Especially notorious are
applications written to run on Intel-based machines.) By
default the library will create new files with the native
byte-order of the <small>CPU</small> on which the
application is run. This ensures optimal performance and is
portable to any application that conforms to the TIFF
specification. To force the library to use a specific
byte-order when creating a new file the
‘‘b’’ and
‘‘l’’ option flags may be included
in the call to open a file; for example,
‘‘wb’’ or
‘‘wl’’.</p>

<td width="91%">
<p>The routines described here provide a high-level
interface through which <small>TIFF</small> images may be
read into memory. Images may be strip- or tile-based and
have a variety of different characteristics: bits/sample,
samples/pixel, photometric, etc. Decoding state is
encapsulated in a <i>TIFFRGBAImage</i> structure making it
possible to capture state for multiple images and quickly
switch between them. The target raster format can be
customized to a particular application’s needs by
installing custom routines that manipulate image data
according to application requirements.</p>
<!-- INDENTATION -->
<p>The default usage for these routines is: check if an
image can be processed using <i>TIFFRGBAImageOK</i>,
construct a decoder state block using
<i>TIFFRGBAImageBegin</i>, read and decode an image into a
target raster using <i>TIFFRGBAImageGet</i>, and then
release resources using <i>TIFFRGBAImageEnd</i>.
<i>TIFFRGBAImageGet</i> can be called multiple times to
decode an image using different state parameters. If
multiple images are to be displayed and there is not enough
space for each of the decoded rasters, multiple state blocks
can be managed and then calls can be made to
<i>TIFFRGBAImageGet</i> as needed to display an image.</p>
<!-- INDENTATION -->
<p>The generated raster is assumed to be an array of
<i>width</i> times <i>height</i> 32-bit entries, where
<i>width</i> must be less than or equal to the width of the
image (<i>height</i> may be any non-zero size). If the
raster dimensions are smaller than the image, the image data
is cropped to the raster bounds. If the raster height is
greater than that of the image, then the image data are
placed in the lower part of the raster. (Note that the
raster is assume to be organized such that the pixel at
location (<i>x</i>,<i>y</i>) is
<i>raster</i>[<i>y</i>*<i>width</i>+<i>x</i>]; with the
raster origin in the <b>lower-left</b> hand corner.)</p>
<!-- INDENTATION -->
<p>Raster pixels are 8-bit packed red, green, blue, alpha
samples. The macros <i>TIFFGetR</i>, <i>TIFFGetG</i>,
<i>TIFFGetB</i>, and <i>TIFFGetA</i> should be used to
access individual samples. Images without Associated Alpha
matting information have a constant Alpha of 1.0 (255).</p>
<!-- INDENTATION -->
<p><i>TIFFRGBAImageGet</i> converts non-8-bit images by
scaling sample values. Palette, grayscale, bilevel,
<small>CMYK</small> , and YCbCr images are converted to
<small>RGB</small> transparently. Raster pixels are returned
uncorrected by any colorimetry information present in the
directory.</p>
<!-- INDENTATION -->
<p>The parameter <i>stopOnError</i> specifies how to act if
an error is encountered while reading the image. If
<i>stopOnError</i> is non-zero, then an error will terminate
the operation; otherwise <i>TIFFRGBAImageGet</i> will
continue processing data until all the possible data in the
image have been requested.</p>

<p>To use the core support for reading and processing
<small>TIFF</small> images, but write the resulting raster
data in a different format one need only override the
‘‘<i>put methods</i>’’ used to store
raster data. These methods are are defined in the
<i>TIFFRGBAImage</i> structure and initially setup by
<i>TIFFRGBAImageBegin</i> to point to routines that pack
raster data in the default <small>ABGR</small> pixel format.
Two different routines are used according to the physical
organization of the image data in the file:
<i>PlanarConfiguration</i>=1 (packed samples), and
<i>PlanarConfiguration</i>=2 (separated samples). Note that
this mechanism can be used to transform the data before
storing it in the raster. For example one can convert data
to colormap indices for display on a colormap display.</p>

<p>It is simple to display an image as it is being read into
memory by overriding the put methods as described above for
supporting alternate raster formats. Simply keep a reference
to the default put methods setup by
<i>TIFFRGBAImageBegin</i> and then invoke them before or
after each display operation. For example, the
<i>tiffgt</i>(1) utility uses the following put method to
update the display as the raster is being filled:</p>
<!-- INDENTATION -->
<pre>static void
putContigAndDraw(TIFFRGBAImage* img, uint32* raster,
uint32 x, uint32 y, uint32 w, uint32 h,
int32 fromskew, int32 toskew,
unsigned char* cp)
{
(*putContig)(img, raster, x, y, w, h, fromskew, toskew, cp);
if (x+w == width) {
w = width;
if (img->orientation == ORIENTATION_TOPLEFT)
lrectwrite(0, y-(h-1), w-1, y, raster-x-(h-1)*w);
else
lrectwrite(0, y, w-1, y+h-1, raster);
}
}

<p><i>TIFFReadRGBATile</i> reads a single tile of a
tile-based image into memory, storing the result in the user
supplied RGBA <i>raster</i>. The raster is assumed to be an
array of width times length 32-bit entries, where width is
the width of a tile (TIFFTAG_TILEWIDTH) and length is the
height of a tile (TIFFTAG_TILELENGTH).</p>
<!-- INDENTATION -->
<p>The <i>x</i> and <i>y</i> values are the offsets from the
top left corner to the top left corner of the tile to be
read. They must be an exact multiple of the tile width and
length.</p>
<!-- INDENTATION -->
<p>Note that the raster is assume to be organized such that
the pixel at location (<i>x</i>,<i>y</i>) is
<i>raster</i>[<i>y</i>*<i>width</i>+<i>x</i>]; with the
raster origin in the <i>lower-left hand corner</i> of the
tile. That is bottom to top organization. Edge tiles which
partly fall off the image will be filled out with
appropriate zeroed areas.</p>
<!-- INDENTATION -->
<p>Raster pixels are 8-bit packed red, green, blue, alpha
samples. The macros <i>TIFFGetR</i>, <i>TIFFGetG</i>,
<i>TIFFGetB</i>, and <i>TIFFGetA</i> should be used to
access individual samples. Images without Associated Alpha
matting information have a constant Alpha of 1.0 (255).</p>

<p>See the <i>TIFFRGBAImage</i>(3TIFF) page for more details
on how various image types are converted to RGBA values.</p>

<p>Samples must be either 1, 2, 4, 8, or 16 bits.

<!-- INDENTATION -->
<p><i>TIFFReadRGBATile</i> is just a wrapper around the more
general <i>TIFFRGBAImage</i>(3TIFF) facilities. It’s
main advantage over the similar <i>TIFFReadRGBAImage()</i>
function is that for large images a single buffer capable of
holding the whole image doesn’t need to be allocated,
only enough for one tile. The <i>TIFFReadRGBAStrip()</i>
function does a similar operation for stripped images.</p>

<p>Return the data for the tile <i>containing</i> the
specified coordinates. The data placed in <i>buf</i> are
returned decompressed and, typically, in the native byte-
and bit-ordering, but are otherwise packed (see further
below). The buffer must be large enough to hold an entire
tile of data. Applications should call the routine
<i>TIFFTileSize</i> to find out the size (in bytes) of a
tile buffer. The <i>x</i> and <i>y</i> parameters are always
used by <i>TIFFReadTile</i>. The <i>z</i> parameter is used
if the image is deeper than 1 slice
(<i>ImageDepth</i>>1). The <i>sample</i> parameter is
used only if data are organized in separate planes
(<i>PlanarConfiguration</i>=2).</p>

differences between the image and the native machine by
converting data to the native machine order. Bit reversal is
done if the <i>FillOrder</i> tag is opposite to the native
machine bit order. 16- and 32-bit samples are automatically
byte-swapped if the file was written with a byte order
opposite to the native machine byte order,</p>

<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b><i>TIFFSetField</i></b>
sets the value of a field or pseudo-tag in the current
directory associated with the open <small>TIFF</small> file
<i>tif</i>. (A <i>pseudo-tag</i> is a parameter that is used
to control the operation of the <small>TIFF</small> library
but whose value is not read or written to the underlying
file.) To set the value of a field the file must have been
previously opened for writing with <i>TIFFOpen</i>(3TIFF);
pseudo-tags can be set whether the file was opened for
reading or writing. The field is identified by <i>tag</i>,
one of the values defined in the include file <b>tiff.h</b>
(see also the table below). The actual value is specified
using a variable argument list, as prescribed by the
<i>stdarg</i>(3) interface (or, on some machines, the
<i>varargs</i>(3) interface.)</p>
<p style="margin-left:11%; margin-top: 1em"><i>TIFFVSetField</i>
is functionally equivalent to <i>TIFFSetField</i> except
that it takes a pointer to a variable argument list.
<i>TIFFVSetField</i> is useful for writing routines that are
layered on top of the functionality provided by
<i>TIFFSetField</i>.</p>
<p style="margin-left:11%; margin-top: 1em">The tags
understood by <i>libtiff</i>, the number of parameter
values, and the expected types for the parameter values are
shown below. The data types are: <i>char*</i> is
null-terminated string and corresponds to the
<small>ASCII</small> data type; <i>uint16</i> is an unsigned
16-bit value; <i>uint32</i> is an unsigned 32-bit value;
<i>uint16*</i> is an array of unsigned 16-bit values.
<i>void*</i> is an array of data values of unspecified
type.</p>
<p style="margin-left:11%; margin-top: 1em">Consult the
<small>TIFF</small> specification for information on the
meaning of each tag.</p>

<p><i>TIFFWarning</i> invokes the library-wide warning
handler function to (normally) write a warning message to
the <b>stderr</b>. The <i>fmt</i> parameter is a
<i>printf</i>(3S) format string, and any number arguments
can be supplied. The <i>module</i> parameter is interpreted
as a string that, if non-zero, should be printed before the
message; it typically is used to identify the software
module in which a warning is detected.</p>
<!-- INDENTATION -->
<p>Applications that desire to capture control in the event
of a warning should use <i>TIFFSetWarningHandler</i> to
override the default warning handler. A <small>NULL</small>

<p><i>TIFFWriteDirectory</i> will write the contents of the
current directory to the file and setup to create a new
subfile in the same file. Applications only need to call
<i>TIFFWriteDirectory</i> when writing multiple subfiles to
a single <small>TIFF</small> file. <i>TIFFWriteDirectory</i>
is automatically called by <i>TIFFClose</i> and
<i>TIFFFlush</i> to write a modified directory if the file
is open for writing.</p>
<!-- INDENTATION -->
<p>The <i>TIFFRewriteDirectory</i> function operates
similarly to <i>TIFFWriteDirectory,</i> but can be called
with directories previously read or written that already
have an established location in the file. It will rewrite
the directory, but instead of place it at it’s old
location (as <i>TIFFWriteDirectory</i> would) it will place
them at the end of the file, correcting the pointer from the
preceeding directory or file header to point to it’s
new location. This is particularly important in cases where
the size of the directory and pointed to data has grown, so
it won’t fit in the space available at the old
location.</p>
<!-- INDENTATION -->
<p>The <i>TIFFCheckpointDirectory</i> writes the current
state of the tiff directory into the file to make what is
currently in the file readable. Unlike
<i>TIFFWriteDirectory, TIFFCheckpointDirectory</i> does not
free up the directory data structures in memory, so they can
be updated (as strips/tiles are written) and written again.
Reading such a partial file you will at worst get a tiff
read error for the first strip/tile encountered that is
incomplete, but you will at least get all the valid data in
the file before that. When the file is complete, just use
<i>TIFFWriteDirectory</i> as usual to finish it off
cleanly.</p>

<p><i>libtiff</i> supports a variety of compression schemes
implemented by software <i>codecs</i>. Each codec adheres to
a modular interface that provides for the decoding and
encoding of image data; as well as some other methods for
initialization, setup, cleanup, and the control of default
strip and tile sizes. Codecs are identified by the
associated value of the <small>TIFF</small>
<i>Compression</i> tag; e.g. 5 for <small>LZW</small>
compression.</p>

<p>The <i>TIFFRegisterCODEC</i> routine can be used to

<p>TIFF supports several color spaces for images stored in
that format. There is usually a problem of application to
handle the data properly and convert between different
colorspaces for displaying and printing purposes. To
simplify this task libtiff implements several color
conversion routines itself. In particular, these routines
used in <b>TIFFRGBAImage(3TIFF)</b> interface.</p>

<p><i>luma</i> is a float array of three values representing
proportions of the red, green and blue in luminance, Y (see
section 21 of the TIFF 6.0 specification, where the YCbCr
images discussed). <i>TIFFTAG_YCBCRCOEFFICIENTS</i> holds
that values in TIFF file. <i>refBlackWhite</i> is a float
array of 6 values which specifies a pair of headroom and
footroom image data values (codes) for each image component
(see section 20 of the TIFF 6.0 specification where the
colorinmetry fields discussed).
<i>TIFFTAG_REFERENCEBLACKWHITE</i> is responsible for
storing these values in TIFF file. Following code snippet
should helps to understand the the technique:</p>

<p>The following routines return status information about an
open <small>TIFF</small> file.</p>
<!-- INDENTATION -->
<p><i>TIFFCurrentDirectory</i> returns the index of the
current directory (directories are numbered starting at 0).
This number is suitable for use with the
<i>TIFFSetDirectory</i> routine.</p>
<!-- INDENTATION -->
<p><i>TIFFLastDirectory</i> returns a non-zero value if the
current directory is the last directory in the file;
otherwise zero is returned.</p>
<!-- INDENTATION -->
<p><i>TIFFCurrentRow</i>, <i>TIFFCurrentStrip</i>, and
<i>TIFFCurrentTile</i>, return the current row, strip, and
tile, respectively, that is being read or written. These
values are updated each time a read or write is done.</p>
<!-- INDENTATION -->
<p><i>TIFFFileno</i> returns the underlying file descriptor
used to access the <small>TIFF</small> image in the
filesystem.</p>
<!-- INDENTATION -->
<p><i>TIFFFileName</i> returns the pathname argument passed
to <i>TIFFOpen</i> or <i>TIFFFdOpen</i>.</p>
<!-- INDENTATION -->
<p><i>TIFFGetMode</i> returns the mode with which the
underlying file was opened. On <small>UNIX</small> systems,
this is the value passed to the <i>open</i>(2) system
call.</p>
<!-- INDENTATION -->
<p><i>TIFFIsTiled</i> returns a non-zero value if the image
data has a tiled organization. Zero is returned if the image
data is organized in strips.</p>
<!-- INDENTATION -->
<p><i>TIFFIsByteSwapped</i> returns a non-zero value if the
image data was in a different byte-order than the host
machine. Zero is returned if the TIFF file and local host
byte-orders are the same. Note that TIFFReadTile(),
TIFFReadStrip() and TIFFReadScanline() functions already
normally perform byte swapping to local host order if
needed.</p>
<!-- INDENTATION -->
<p><i>TIFFIsUpSampled</i> returns a non-zero value if image
data returned through the read interface routines is being
up-sampled. This can be useful to applications that want to
calculate I/O buffer sizes to reflect this usage (though the
usual strip and tile size routines already do this).</p>
<!-- INDENTATION -->
<p><i>TIFFIsMSB2LSB</i> returns a non-zero value if the
image data is being returned with bit 0 as the most
significant bit.</p>
<!-- INDENTATION -->
<p><i>TIFFGetVersion</i> returns an <small>ASCII</small>
string that has a version stamp for the <small>TIFF</small>
library software.</p>

<p><i>TIFFDefaultStripSize</i> returns the number of rows
for a reasonable-sized strip according to the current
settings of the <i>ImageWidth</i>, <i>BitsPerSample</i>,
<i>SamplesPerPixel</i>, tags and any compression-specific
requirements. If the <i>estimate</i> parameter, if non-zero,
then it is taken as an estimate of the desired strip size
and adjusted according to any compression-specific
requirements. The value returned by this function is
typically used to define the <i>RowsPerStrip</i> tag. In
lieu of any unusual requirements <i>TIFFDefaultStripSize</i>
tries to create strips that have approximately 8 kilobytes
of uncompressed data.</p>
<!-- INDENTATION -->
<p><i>TIFFStripSize</i> returns the equivalent size for a
strip of data as it would be returned in a call to
<i>TIFFReadEncodedStrip</i> or as it would be expected in a

out-of-range coordinate values are clamped to the bounds of

<p><i>TIFFDefaultTileSize</i> returns the pixel width and
height of a reasonable-sized tile; suitable for setting up
the <i>TileWidth</i> and <i>TileLength</i> tags. If the
<i>tw</i> and <i>th</i> values passed in are non-zero, then
they are adjusted to reflect any compression-specific
requirements. The returned width and height are constrained
to be a multiple of 16 pixels to conform with the
<small>TIFF</small> specification.</p>
<!-- INDENTATION -->
<p><i>TIFFTileSize</i> returns the equivalent size for a
tile of data as it would be returned in a call to
<i>TIFFReadTile</i> or as it would be expected in a call to
<i>TIFFWriteTile</i>.</p>
<!-- INDENTATION -->
<p><i>TIFFVTileSize</i> returns the number of bytes in a
row-aligned tile with <i>nrows</i> of data.</p>
<!-- INDENTATION -->
<p><i>TIFFTileRowSize</i> returns the number of bytes of a

out-of-range coordinate values are clamped to the bounds of
the image. The <i>x</i> and <i>y</i> parameters are always
used in calculating a tile. The <i>z</i> parameter is used
if the image is deeper than 1 slice
(<i>ImageDepth</i>>1). The <i>sample</i> parameter is
used only if data are organized in separate planes
(<i>PlanarConfiguration</i>=2).</p>
<!-- INDENTATION -->
<p><i>TIFFCheckTile</i> returns a non-zero value if the
supplied coordinates are within the bounds of the image and
zero otherwise. The <i>x</i> parameter is checked against
the value of the <i>ImageWidth</i> tag. The <i>y</i>
parameter is checked against the value of the
<i>ImageLength</i> tag. The <i>z</i> parameter is checked
against the value of the <i>ImageDepth</i> tag (if defined).
The <i>sample</i> parameter is checked against the value of
the <i>SamplesPerPixel</i> parameter if the data are
organized in separate planes.</p>

<p><i>fax2ps</i> reads one or more <small>TIFF</small>
facsimile image files and prints a compressed form of
PostScript on the standard output that is suitable for
printing.</p>
<!-- INDENTATION -->
<p>By default, each page is scaled to reflect the image
dimensions and resolutions stored in the file. The
<b>−x</b> and <b>−y</b> options can be used to
specify the horizontal and vertical image resolutions
(lines/inch), respectively. If the <b>−S</b> option is
specified, each page is scaled to fill an output page. The
default output page is 8.5 by 11 inches. Alternate page
dimensions can be specified in inches with the
<b>−W</b> and <b>−H</b> options.</p>
<!-- INDENTATION -->
<p>By default <i>fax2ps</i> generates PostScript for all
pages in the file. The <b>−p</b> option can be used to
select one or more pages from a multi-page document.</p>
<!-- INDENTATION -->
<p><i>fax2ps</i> generates a compressed form of PostScript
that is optimized for sending pages of text to a PostScript
printer attached to a host through a low-speed link (such as
a serial line). Each output page is filled with white and
then only the black areas are drawn. The PostScript
specification of the black drawing operations is optimized
by using a special font that encodes the move-draw
operations required to fill the black regions on the page.
This compression scheme typically results in a substantially
reduced PostScript description, relative to the
straightforward imaging of the page with a PostScript
<i>image</i> operator. This algorithm can, however, be
ineffective for continuous-tone and white-on-black images.
For these images, it sometimes is more efficient to send the
raster bitmap image directly; see <b>tiff2ps</b>(1).</p>

<p><i>Fax2tiff</i> creates a <small>TIFF</small> file
containing <small>CCITT</small> Group 3 or Group 4 encoded
data from one or more files containing
‘‘raw’’ Group 3 or Group 4 encoded
data (typically obtained directly from a fax modem). By
default, each row of data in the resultant
<small>TIFF</small> file is 1-dimensionally encoded and
padded or truncated to 1728 pixels, as needed. The resultant
image is a set of low resolution (98 lines/inch) or medium
resolution (196 lines/inch) pages, each of which is a single
strip of data. The generated file conforms to the
<small>TIFF</small> Class F ( <small>FAX</small> )
specification for storing facsimile data. This means, in
particular, that each page of the data does <b>not</b>
include the trailing <i>return to control</i> (
<small>RTC</small> ) code; as required for transmission by
the <small>CCITT</small> Group 3 specifications. The old,
‘‘classic’’, format is created if
the <b>−c</b> option is used. (The Class F format can
also be requested with the <b>−f</b> option.)</p>
<!-- INDENTATION -->
<p>The default name of the output image is <i>fax.tif</i>;
this can be changed with the <b>−o</b> option. Each
input file is assumed to be a separate page of facsimile
data from the same document. The order in which input files
are specified on the command line is the order in which the
resultant pages appear in the output file.</p>

<p><big><i>libtiff</i> is a library for reading and writing
data files encoded with the <i>Tag Image File</i> format,
Revision 6.0 (or revision 5.0 or revision 4.0). This file
format is suitable for archiving multi-color and
monochromatic image data.</big></p>
<!-- INDENTATION -->
<p><big>The library supports several compression algorithms,
as indicated by the <i>Compression</i> field, including: no
compression (1),</big> CCITT <big>1D Huffman compression
(2),</big> CCITT <big>Group 3 Facsimile compression
(3),</big> CCITT <big>Group 4 Facsimile compression (4),
Lempel-Ziv & Welch compression (5), baseline JPEG
compression (7), word-aligned 1D Huffman compression
(32771), and PackBits compression (32773). In addition,
several nonstandard compression algorithms are supported:
the 4-bit compression algorithm used by the
<i>ThunderScan</i> program (32809) (decompression only),
NeXT’s 2-bit compression algorithm (32766)
(decompression only), an experimental LZ-style algorithm
known as Deflate (32946), and an experimental CIE LogLuv
compression scheme designed for images with high dynamic
range (32845 for LogL and 32845 for LogLuv). Directory
information may be in either little- or big-endian byte
order−byte swapping is automatically done by the
library. Data bit ordering may be either Most Significant
Bit (</big> MSB <big>) to Least Significant Bit (</big> LSB
<big>) or</big> LSB <big>to</big> MSB. <big>Finally, the
library does not support files in which the
<i>BitsPerSample</i>, <i>Compression</i>,
<i>MinSampleValue</i>, or <i>MaxSampleValue</i> fields are
defined differently on a per-sample basis (in Rev. 6.0 the
<i>Compression</i> tag is not defined on a per-sample basis,
so this is immaterial).</big></p>

either through function definitions or through parameters
passed through the varargs interfaces.</big></p></td>

quantities by 32-bit fields they are stored in in the</big>
TIFF <big>image. Likewise <i>tsample_t</i> is limited by the
16-bit field used to store the <i>SamplesPerPixel</i> tag.
<i>tdir_t</i> constrains the maximum number of</big> IFDs
<big>that may appear in an image and may be an arbitrary
size (w/o penalty). <i>ttag_t</i> must be either int,
unsigned int, pointer, or double because the library uses a
varargs interface and</big> ANSI C <big>restricts the type
of the parameter before an ellipsis to be a promoted type.
<i>toff_t</i> is defined as int32 because TIFF file offsets
are (unsigned) 32-bit quantities. A signed value is used
because some interfaces return −1 on error. Finally,
note that user-specified data references are passed as
opaque handles and only cast at the lowest layers where
their type is presumed.</big></p>

<p><i>raw2tiff</i> can guess image width and height in case
one or both of these parameters are not specified. If you
omit one of those parameters, the complementary one will be
calculated based on the file size (taking into account
header size, number of bands and data type). If you omit
both parameters, the statistical approach will be used.
Utility will compute correlation coefficient between two
lines at the image center using several appropriate line
sizes and the highest absolute value of the coefficient will
indicate the right line size. That is why you should be
cautious with the very large images, because guessing
process may take a while (depending on your system
performance). Of course, the utility can’t guess the
header size, number of bands and data type, so it should be
specified manually. If you don’t know anything about
your image, just try with the several combinations of those
options.</p>
<!-- INDENTATION -->
<p>There is no magic, it is just a mathematical statistics,
so it can be wrong in some cases. But for most ordinary
images guessing method will work fine.</p>

<!-- INDENTATION -->
<p>The program converts one TIFF file to one PDF file,

<i>libtiff</i> and PDF.</p>
<!-- INDENTATION -->
<p>If you have multiple TIFF files to convert into one PDF
file then use <i>tiffcp</i> or other program to concatenate
the files into a multiple page TIFF file. If the input TIFF
file is of huge dimensions (greater than 10000 pixels height
or width) convert the input image to a tiled TIFF if it is
not already.</p>
<!-- INDENTATION -->
<p>The standard output is standard output. Set the output

option.</p>
<!-- INDENTATION -->
<p>All black and white files are compressed into a single
strip CCITT G4 Fax compressed PDF, unless tiled, where tiled
black and white images are compressed into tiled CCITT G4
Fax compressed PDF, <i>libtiff</i> CCITT support is
assumed.</p>
<!-- INDENTATION -->
<p>Color and grayscale data can be compressed using either
JPEG compression, ITU-T T.81, or Zip/Deflate LZ77
compression. Set the compression type using the
<b>−j</b> or <b>−z</b> options. JPEG compression
support requires that <i>libtiff</i> be configured with JPEG
support, and Zip/Deflate compression support requires that
<i>libtiff</i> be configured with Zip support, in
tiffconf.h. Use only one or the other of <b>−j</b> and
<b>−z.</b></p>
<!-- INDENTATION -->
<p>If the input TIFF contains single strip CCITT G4 Fax
compressed information, then that is written to the PDF file
without transcoding, unless the options of no compression
and no passthrough are set, <b>−d</b> and
<b>−n.</b></p>
<!-- INDENTATION -->
<p>If the input TIFF contains JPEG or single strip
Zip/Deflate compressed information, and they are configured,
then that is written to the PDF file without transcoding,
unless the options of no compression and no passthrough are
set.</p>
<!-- INDENTATION -->
<p>The default page size upon which the TIFF image is placed
is determined by the resolution and extent of the image
data. Default values for the TIFF image resolution can be
set using the <b>−x</b> and <b>−y</b> options.
The page size can be set using the <b>−p</b> option
for paper size, or <b>−w</b> and <b>−l</b> for
paper width and length, then each page of the TIFF image is
centered on its page. The distance unit for default
resolution and page width and length can be set by the
<b>−u</b> option, the default unit is inch.</p>
<!-- INDENTATION -->
<p>Various items of the output document information can be
set with the <b>−e</b>, <b>−c</b>,
<b>−a</b>, <b>−t</b>, <b>−s</b>, and
<b>−k</b> options. Setting the argument of the option
to "" for these tags causes the relevant document
information field to be not written. Some of the document
information values otherwise get their information from the
input TIFF image, the software, author, document name, and
image description.</p>

<p><i>tiff2ps</i> reads <small>TIFF</small> images and
writes PostScript or Encapsulated PostScript (EPS) on the
standard output. By default, <i>tiff2ps</i> writes
Encapsulated PostScript for the first image in the specified
<small>TIFF</small> image file.</p>
<!-- INDENTATION -->
<p>By default, <i>tiff2ps</i> will generate PostScript that
fills a printed area specified by the <small>TIFF</small>
tags in the input file. If the file does not contain
<i>XResolution</i> or <i>YResolution</i> tags, then the
printed area is set according to the image dimensions. The
<b>−w</b> and <b>−h</b> options (see below) can
be used to set the dimensions of the printed area in inches;
overriding any relevant <small>TIFF</small> tags.</p>
<!-- INDENTATION -->
<p>The PostScript generated for <small>RGB,</small> palette,
and <small>CMYK</small> images uses the <i>colorimage</i>
operator. The PostScript generated for greyscale and bilevel
images uses the <i>image</i> operator. When the
<i>colorimage</i> operator is used, PostScript code to
emulate this operator on older PostScript printers is also
generated. Note that this emulation code can be very
slow.</p>
<!-- INDENTATION -->
<p>Color images with associated alpha data are composited
over a white background.</p>

<p><i>Tiff2rgba</i> converts a wide variety of TIFF images
into an RGBA TIFF image. This includes the ability to
translate different color spaces and photometric
interpretation into RGBA, support for alpha blending, and
translation of many different bit depths into a 32bit RGBA
image.</p>
<!-- INDENTATION -->
<p>Internally this program is implemented using the
<i>TIFFReadRGBAImage()</i> function, and it suffers any
limitations of that image. This includes limited support for
> 8 BitsPerSample images, and flaws with some esoteric
combinations of BitsPerSample, photometric interpretation,
block organization and planar configuration.</p>
<!-- INDENTATION -->
<p>The generated images are stripped images with four
samples per pixel (red, green, blue and alpha) or if the
<b>−n</b> flag is used, three samples per pixel (red,
green, and blue). The resulting images are always planar
configuration contiguous. For this reason, this program is a
useful utility for transform exotic TIFF files into a form
ingestible by almost any TIFF supporting software.</p>

each scanline of the output image to undergo horizontal
differencing before it is encoded; a value of 1 forces each
scanline to be encoded without differencing. LZW-specific
options are specified by appending a
‘‘:’’-separated list to the
‘‘lzw’’ option; e.g. <b>−c
lzw:2</b> for <small>LZW</small> compression with horizontal

<p><i>tiffcrop</i> combines one or more files created
according to the Tag Image File Format, Revision 6.0 into a
single <small>TIFF</small> file. The output file may be
compressed using a different algorithm than the input files.
<i>tiffcrop</i> is most often used to extract portions of an
image for processing with bar code recognizer or OCR
software when that software cannot restrict the region of
interest to a specific portion of the image or to improve
efficiency when the regions of interest must be rotated.</p>
<!-- INDENTATION -->
<p>By default, <i>tiffcrop</i> will copy all the understood
tags in a <small>TIFF</small> directory of an input file to
the associated directory in the output file.</p>
<!-- INDENTATION -->
<p><i>tiffcrop</i> can be used to reorganize the storage
characteristics of data in a file, and it will alter or
convert the image data content as specified at the same
time, unlike tiffcp.</p>
<!-- INDENTATION -->
<p><i>tiffcrop</i> will behave exactly like tiffcp if none
of the new options are specified.</p>

<p>Group 3 compression can be specified together with
several T.4-specific options: <b>1d</b> for 1-dimensional
encoding, <b>2d</b> for 2-dimensional encoding, and
<b>fill</b> to force each encoded scanline to be zero-filled
so that the terminating EOL code lies on a byte boundary.
Group 3-specific options are specified by appending a
‘‘:’’-separated list to the
‘‘g3’’ option; e.g. <b>−c
g3:2d:fill</b> to get 2D-encoded data with byte-aligned EOL
codes.</p>
<!-- INDENTATION -->
<p><small>LZW</small> compression can be specified together
with a <i>predictor</i> value. A predictor value of 2 causes
each scanline of the output image to undergo horizontal
differencing before it is encoded; a value of 1 forces each
scanline to be encoded without differencing. LZW-specific
options are specified by appending a
‘‘:’’-separated list to the
‘‘lzw’’ option; e.g. <b>−c
lzw:2</b> for <small>LZW</small> compression with horizontal

<p><i>tiffmedian</i> applies the median cut algorithm to an
<small>RGB</small> image in <i>input.tif</i> to generate a
palette image that is written to <i>output.tif</i>. The
generated colormap has, by default, 256 entries. The image
data is quantized by mapping each pixel to the closest color
values in the colormap.</p>

<p><small>LZW</small> compression can be specified together
with a <i>predictor</i> value. A predictor value of 2 causes
each scanline of the output image to undergo horizontal
differencing before it is encoded; a value of 1 forces each
scanline to be encoded without differencing. LZW-specific
options are specified by appending a
‘‘:’’-separated list to the
‘‘lzw’’ option; e.g. <b>−c
lzw:2</b> for <small>LZW</small> compression with horizontal
differencing.</p>

function to (normally) write an error message to the
<b>stderr</b>. The <i>fmt</i> parameter is a

is printed before the message; it typically is used to
identify the software module in which an error is
detected.</p>

<p>Applications that desire to capture control in the event
of an error should use <i>TIFFSetErrorHandler</i> to

<LI>support was added for building the library as a DSO under HP-UX with
the native C compiler
<LI>tools are now built with explicit pathnames for the DSO under IRIX,
Solaris, and Linux
<LI>DSO configuration support for Linux was changed to require that
<B>libc.so</B> only be readable (not executable)
</UL>

<LI>a bug was fixed whereby certain multi-directory files were not
properly handled when accessed by mapping the data into memory
<LI>the strip chopping support is now always compiled
into the library with the default usage controlled by a
<TT>STRIPCHOP_DEFAULT</TT> configuration parameter
<LI>the strip chopping support no longer chops tiled images
<LI>all static strings are now const--for shared libraries
<LI>the logic for estimating the strip size of images without
a <TT>StripByteCounts</TT> tag was improved by handling
<TT>PlanarContig</TT> images differently from <TT>PlanarSeparate</TT>
<LI>a bug was fixed in the G3 codec when converting the Y resolution
of data specified in metric units
<LI>a bug was fixed in the G3/G4 decoder for data where lines terminate
with a v0 code
<LI>the <TT>TIFFRGBAImage</TT> support was changed to scale 16-bit colormap
entries more conservatively to avoid problems with applications
that do not generate fully saturated pixel values
<LI>the LZW decoder was changed to use a more conservative scheme when
bounds checking the hash table array; this avoids pitfalls with
systems that load objects into memory in unusual locations
<LI>a bug was fixed in <TT>TIFFPrintDirectory</TT>'s handling of the
<TT>InkNames</TT> tag

<p>
The ChangeLog will follow, but please note the most important change:
LZW compression has been removed.
<p>
Unisys has the patent on LZW compression and have been very active in
their enforcement of late, demanding payments of $5000 or more from
websites using unlicensed software to create GIF's. They could well
do the same do persons using libtiff to create LZW compressed TIFF
images.
<p>
From <A HREF=http://burnallgifs.org>Burn All GIF's Day</a>:
<br>
<em>The catch is that it appears to be difficult or impossible to get a
Unisys license to use LZW in free software that complies with the Open
Source Definition</em>
<P>
Unfortunatly, the removal of LZW compression means that saved image size has
grown dramatically. Without a change in the TIFF spec to support
another lossless compression format, this is unavoidable.
<P>
The library can use zip for lossless compression, but as this is not
part of the spec, TIFFs using zip compression may not work with other
software
<P>
We will be making a patch available that will contain the LZW
compression code for users who have either obtained a license from
Unisys or are willing to risk it.
<p>
LZW decompression is unchanged.
<p>
<P><HR WIDTH=65% ALIGN=left>
<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>

<LI> Added zip creation to release makefile target
</UL>
<P><HR WIDTH=65% ALIGN=left>
<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
<UL>
<LI> Added html for TIFFWriteTile.3t man page.
<LI> Added some changes to tif_write.c to support rewriting existing
fixed sized tiles and strips. Code mods disabled by default, only
enabled if REWRITE_HACK is defined for now.
<LI> Added TIFFWriteTile.3t man page.
<LI> Added notes on use of makefile.vc in build.html, and fixed
email subscription address.
<LI> Fixed apocalypse-inducing y2k bug in contrib/ras/ras2tiff.c
<LI> Did some casts cleaning up to reduce compiler warnings in tif_fax3.c,
from Bruce Carmeron <cameron@petris.com> -- modifications of
changes made by Frank (sun cc still complained on cast).
<LI> fixed various VC++ warnings as suggested by Gilles Vollant
<info@winimage.com>.
<LI> Modified TIFFquery.3t man pages info on TIFFIsByteSwapped() to
not imply applications are responsible for image data swapping.
<LI> HTML-ized the man pages, added to html/man
<LI> Removed LZW Compression to comply with Unisys patent extortion.
<LI> Corrected one remaining 16 -> 32 bit value in tif_fax3.c,
From Ivo Penzar <ivo.penzar@infolink-software.com.
<LI> Added patch from Ivo Penzar to have TiffAdvanceDirectory handle
memory mapped files. <ivo.penzar@infolink-software.com>

<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
<UL>
<LI> tif_dir.c: Clear TIFF_ISTILED flag in TIFFDefaultDirectory
as per http://bugzilla.remotesensing.org/show_bug.cgi?id=18
from vandrove@vc.cvut.cz.
<LI> Modified tif_packbits.c decoding to avoid overrunning the
output buffer, and to issue a warning if data needs to be
discarded. See http://bugzilla.remotesensing.org/show_bug.cgi?id=18
<LI> Modified TIFFClientOpen() to emit an error on an attempt to
open a comperessed file for update (O_RDWR/r+) access. This is
because the compressor/decompressor code gets very confused when
the mode is O_RDWR, assuming this means writing only. See
bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13
<LI> Applied patch for 0x0000 sequences in tif_fax3.h's definition
of EXPAND1D() as per bug 11 (from Roman).
<LI> Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
cygwin compatibility.
<LI> Applied patch from Roman Shpount to tif_fax3.c. This seems to
be a proper fix to the buffer sizing problem. See
http://bugzilla.remotesensing.org/show_bug.cgi?id=11
<LI> Fixed tif_getimage.c to fix overrun bug with YCbCr images without
downsampling. http://bugzilla.remotesensing.org/show_bug.cgi?id=10
Thanks to Nick Lamb <njl98r@ecs.soton.ac.uk> for reporting the
bug and proving the patch.
<LI> Fixed tif_jpeg.c so avoid destroying the decompressor before
we are done access data thanks to bug report from:
Michael Eckstein <eckstein@gepro.cz>.
<LI> tif_open.c: Don't set MMAP for O_RDWR files.
<LI> tif_open.c: Set STRIPCHOP_DEFAULT for O_RDWR as well as O_RDONLY
so that files opened for update can be strip chopped too.
<LI> tif_read.c: fixed up bug with files missing rowsperstrip and
the strips per separation fix done a few weeks ago.
<LI> Tentatively added support for SAMPLEFORMAT_COMPLEXIEEEFP, and
SAMPLEFORMAT_COMPLEXINT.
<LI> index.html, bugs.html: added bugzilla info.
<LI> tif_read.c: fix subtle bug with determining the number of
rows for strips that are the last strip in a separation but
not the last strip of all in TIFFReadEncodedStrip().
<LI> Applied 16/32 bit fix to tif_fax3.c. Fix supplied by
Peter Skarpetis <peters@serendipity-software.com.au>
<LI> Modified tiffio.h logic with regard to including windows.h. It
won't include it when building with __CYGWIN__.
<LI> README: update to mention www.libtiff.org, don't list Sam's old
email address.
<LI> libtiff/tif_dirread.c: Don't use estimate strip byte count for
one tile/strip images with an offset, and byte count of zero. These
could be "unpopulated" images.
<LI> tif_win32.c: Applied patch to fix overreads and ovverwrites
caught by BoundsChecker. From Arvan Pritchard
<arvan.pritchard@infomatix.co.uk> (untested).
<LI> tif_getimage.c: Applied patch to silence VC6 warnings. From
Arvan Pritchard <arvan.pritchard@informatix.co.uk>
<LI> tif_lzw.c: Applied patch to silence VC6 warnings. From
Arvan Pritchard <arvan.pritchard@informatix.co.uk>
<LI> libtiff/tif_apple.c: Applied "Carbon" support patches supplied by
Leonard Rosenthol <leonardr@lazerware.com>. May interfere
with correct building on older systems. If so, please let me know.

<LI> tools/rgb2ycbcr.c: fixed output strip size to account for vertical
roundup if rows_per_strip not a multiple of vertical sample size.
<LI> tools/tiffsplit.c: Copy TIFFTAG_SAMPLEFORMAT.
<LI> Modified tiff2bw to ensure portions add to 100%, and that
white is properly recovered. See bug

<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
<UL>
<li> libtiff/libtiff.def: Brent Roman submitted new version adding
serveral missing entry points. Also add a few other entry points
later.
<li> configure, Makefile.in, etc: added support for OPTIMIZER being
set from config.site.
<li> config.guess: updated wholesale to an FSF version apparently
from 1998 (as opposed to 1994). This is mainly inspired by
providing for MacOS X support.
<li> configure/config.site: modified to check if -lm is needed for
MACHDEPLIBS if not supplied by config.site. Needed for Darwin.
<li> libtiff/tiff.h: Applied hac to try and resolve the problem
with the inttypes.h include file on AIX. (Bug 39)
<li> configure, *Makefile.in: Various changes to improve configuration
for HP/UX specifically, and also in general. (Bug 40) They include:
<ul>
<li> Try to handle /usr/bin/sh instead of /bin/sh where necessary.
<li> Upgrade to HP/UX 10.x+ compiler, linker and dso options.
<li> Fixed mmap() test to avoid MMAP_FIXED ... it isn't available on HP
<li> Use -${MAKEFLAGS} in sub makes from makefiles.
<li> Fixed SCRIPT_SH/SHELL handling.
</ul>
<li> configure: Changes for DSO generation on AIX provided by
John Marquart <jomarqua@indiana.edu>.
<li> configure, libtiff/Makefile.in: Modified to build DSOs properly
on Darwin thanks to Robert Krajewski (rpk@alum.mit.edu) and
Keisuke Fujii (fujiik@jlcuxf.kek.jp).
<li> configure, libtiff/Makefile.in: applied OpenBSD patches as per bug 61.
<li> Makefile.in: added DESTDIR support as per bug 60.
<li> libtiff/tif_jpeg.c: Define HAVE_BOOLEAN on windows if RPCNDR.H
has been included.
<li> man/Makefile.in: add TIFFClientOpen link as per debian submitted
bug 66.
<li> libtiff/Makefile.in: Fixed @DSOSUB_VERSION to be @DSOSUF_VERSION@
in two places.
</UL>
<P><HR WIDTH=65% ALIGN=left>
<!--------------------------------------------------------------------------->
<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
<UL>
<li> tif_fax3.c: keep rw_mode flag internal to fax3 state to remember
whether we are encoding or decoding. This is to ensure graceful
recovery if TIFFClientOpen() discovers an attempt to open a compressed
file for "r+" access, and subsequently close it, as it resets the
tif_mode flag to O_RDONLY in this case to avoid writes, confusing the
compressor's concept of whether it is in encode or decode mode.
<li> tif_luv.c/tiff.h/tiffio.h:
New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward
(greg@shutterfly.com). He writes:
<ol>
<li> I improved the gamut-mapping function in tif_luv.c for imaginary
colors, because some images were being super-saturated on the input
side and this resulted in some strange color shifts in the output.
<li> I added a psuedotag in tiff.h to control random dithering during
LogLuv encoding. This is turned off by default for 32-bit LogLuv and
on for 24-bit LogLuv output. Dithering improves the average color
accuracy over the image.
<li> I added a #define for LOG_LUV_PUBLIC, which is enabled by default in
tiffio.h, to expose internal routines for converting between LogLuv and
XYZ coordinates. This is helpful for writing more efficient,
specialized conversion routines, especially for reading LogLuv files.
</ol>
<li> libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS.
<li> Added TIFFTAG_COPYRIGHT support.
<li> tif_getimage.c: Added support for 16bit minisblack/miniswhite
images in RGBA interface.
<li> libtiff/tif_dirinfo.c: removed duplicate TIFFTAG_PHOTOSHOP as per
bug 44.
<li> libtiff/tif_dirwrite.c: Added support for TIFF_VARIABLE2 in the
case of writing TIFF_BYTE/TIFF_SBYTE fields as per bug 43.
<li> libtiff/tif_dirinfo.c: Modified the TIFF_BYTE definition for
TIFFTAG_PHOTOSHOP to use a writecount of TIFF_VARIABLE2 (-3) to
force use of uint32 counts instead of short counts.
<li> libtiff/tif_dirinfo.c: moved pixar and copyright flags to
ensure everything is in order.
<li> Integrated experimental OJPEG support from Scott Marovich of HP.
<li> libtiff/tif_open.c: Seek back to zero after failed read,
before writing header.
<li> libtiff/tiff.h, libtiff/tif_fax3.c: added check for __LP64__
when checking for 64 bit architectures as per bugzilla bug 67.
<li> libtiff/tif_getimage.c: Use memmove() instead of TIFFmemcpy()
in TIFFReadRGBATile() to avoid issues in cases of overlapping
buffers. See Bug 69 in Bugzilla.
<li> libtiff/tif_getimage.c: Don't complain for CMYK (separated)
images with more than four samples per pixel as per bug 73.
<li> libtiff/tif_getimage.c: relax handling of contig case where
there are extra samples that are supposed to be ignored as per bug 75. This
should now work for 8bit greyscale or palletted images.
<li> libtiff/tif_packbits.c: fixed memory overrun error as per bug 77.
<li> libtiff/tif_getimage.c: Fixed problem with reading strips or
tiles that don't start on a tile boundary. Fix contributed by
Josep Vallverdu (from HP), and further described in bug 47.
<li> libtif/tif_fax3.c: Removed #ifdef PURIFY logic, and modified to
always use the "safe" version, even if there is a very slight
cost in performance as per bug 54.
<li> libtiff/tif_lzw.c: added dummy LZWSetupEncode() to report an
error about LZW not being available.
<li> libtiff/tif_dir.c: propagate failure to initialize compression
back from TIFFSetField() as an error status, so applications can
detect failure.
<li> libtiff/tif_lzw.c: Avoid MS VC++ 5.0 optimization bug as per bug 78.
<li> libtiff/tif_dirwrite.c: added TIFFRewriteDirectory() function.
Updated TIFFWriteDirectory man page to include TIFFRewriteDirectory.
<li> libtiff/tiff.h: I have created COMPRESSION_CCITT_T4,
COMPRESSION_CCITT_T6, TIFFTAG_T4OPTIONS and TIFFTAG_T6OPTIONS aliases
in keeping with TIFF 6.0 standard in tiff.h as per bug 83.
<li> Added PHOTOMETRIC_ITULAB as per bug 90.

<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A>
<UL>
<li> Brent Roman contributed updated tiffcp utility (and tiffcp.1)
with support for extracting subimages with the ,n syntax, and also
adding the -b bias removal flag.
<li> tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by
Bruce A. Mallett, including a faster encoder, fixes for level
2 PostScript, and support for the imagemask operator.
<li> fax2ps.c: Helge (libtiff at oldach.net) submitted fix
that corrects behaviour for non-Letter paper
sizes. (Bug 35) It fixes two problems:
<br>
Without scaling (-S) the fax is now centered on the page size specified
with -H and/or -W. Before, fax2ps was using an obscure and practially
useless algorithm to allocate the image relative to Letter sized paper
which sometime sled to useless whitespace on the paper, while at the
same time cutting of the faxes printable area at the opposite border.
<br>
Second, scaling now preserves aspect ratio, which makes unusual faxes
(in particular short ones) print properly.
<li> thumbnail.c: changed default output compression
to packbits from LZW since LZW isn't generally available.
<li> tiff2rgba.c: added -n flag to avoid emitting alpha component. Also added
a man page for tiff2rgba.
<li> tiffcmp.c: Fixed multi samples per pixel support for ContigCompare
as per bug 53.
Updated bug section of tiffcmp.1 to note tiled file issues.
<li> libtiff/tif_getimage.c: Fixed so that failure is properly
reported by gtTileContig, gtStripContig, gtTileSeparate and
gtStripSeparate as per bug 51.

<A NAME="lzwkit"><B><FONT SIZE=+3>C</FONT>HANGES IN THE LZW COMPRESSION KIT:</B></A>
<UL>
<LI> Rewrote lzw patching process so that is required to enable full
LZW support is to drop the tif_lzw.c from the
libtiff-lzw-compression-kit over the one in the libtiff directory.
<LI> Some changes were made to make recovery from failure to
initialize the LZW compressor more graceful.
<LI> Note that as distributed libtiff support LZW decompression, but
not LZW compression.

<h3>Custom Tag Support</h3>
The approach to extending libtiff with custom tags has changed radically.
Previously, all internally supported TIFF tags had a place in the
private TIFFDirectory structure within libtiff to hold the values (if read),
and a "field number" (ie. FIELD_SUBFILETYPE) used to identify that tag.
However, every time a new tag was added to the core, the size of the
TIFFDirectory structure would changing, breaking any dynamically linked
software that used the private data structures.<p>
Also, any tag not recognised
by libtiff would not be read and accessable to applications without some
fairly complicated work on the applications part to pre-register the tags
as exemplified by the support for "Geo"TIFF tags by libgeotiff layered on
libtiff. <p>
Amoung other things this approach required the extension code
to access the private libtiff structures ... which made the higher level
non-libtiff code be locked into a specific version of libtiff at compile time.
This caused no end of bug reports!<p>
The new approach is for libtiff to read all tags from TIFF files. Those that
aren't recognised as "core tags" (those having an associated FIELD_ value,
and place for storage in the TIFFDirectory structure) are now read into a
dynamic list of extra tags (td_customValues in TIFFDirectory). When a new
tag code is encountered for the first time in a given TIFF file, a new
anonymous tag definition is created for the tag in the tag definition list.
The type, and some other metadata is worked out from the instance encountered.
These fields are known as "custom tags". <p>
Custom tags can be set and fetched normally using TIFFSetField() and
TIFFGetField(), and appear pretty much like normal tags to application code.
However, they have no impact on internal libtiff processing (such as
compression). Some utilities, such as tiffcp will now copy these custom
tags to the new output files. <p>
As well as the internal work with custom tags, new C API entry points
were added so that extension libraries, such as libgeotiff, could
define new tags more easily without accessing internal data structures.
Because tag handling of extension tags is done via the "custom fields"
mechanism as well, the definition provided externally mostly serves to provide
a meaningful name for the tag.
The addition of "custom tags" and the altered approach to extending libtiff
with externally defined tags is the primary reason for the shift to the
3.6.x version number from 3.5.x.<p>

<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
<UL>
<li> libtiff/tif_getimage.c: New function <A
HREF="./man/TIFFReadRGBAImage.3t.html">TIFFReadRGBAImageOriented()</A>
implemented to retrieve raster array with user-specified origin position.
<li> libtiff/tif_fax3.c: Fix wrong line numbering.
<li> libtiff/tif_dirread.c: Check field counter against number of fields.
<li> Store a list of opened IFD to prevent directory looping.
<li> libtiff/tif_jpeg.c: modified segment_height calculation to always
be a full height tile for tiled images. Also changed error to just
be a warning.

LZWSetupDecode(). Needed to read LZW files in "r+" mode.
<li> libtiff/tif_dir.c: fixed up the tif_postdecode settings responsible
for byte swapping complex image data.
<li> libtiff/tif_open.c: Removed error if opening a compressed file
in update mode bug (198).
<li> libtiff/tif_write.c: TIFFWriteCheck() now fails if the image is
a pre-existing compressed image. That is, image writing to pre-existing
compressed images is not allowed.
<li> html/man/*.html: Web pages regenerated from man pages.
<li> libtiff/tif_jpeg.c: Hack to ensure that "boolean" is defined properly
on Windows so as to avoid the structure size mismatch error from libjpeg
(bug 188).
<li> libtiff/tiff.h: #ifdef USING_VISUALAGE around previous Visual Age
AIX porting hack as it screwed up gcc. (bug 39)
<li> libtiff/tiff.h: added COMPRESSION_JP2000 (34712) for LEAD tools
custom compression.
<li> libtiff/tif_dirread.c: Another fix for the fetching SBYTE arrays
by the TIFFFetchByteArray() function. (bug 52)

fetch TIFFTAG_YCBCRSUBSAMPLING from the jpeg data stream if it isn't
present in the tiff tags as per bug 168.
<li> libtiff/tif_jpeg.c: Fixed problem with setting of nrows in
JPEGDecode() as per bug 129.
<li> libtiff/tif_read.c, libtiff/tif_write.c: TIFFReadScanline() and
TIFFWriteScanline() now set tif_row explicitly in case the codec has
fooled with the value as per bug 129.
<li> libtiff/tif_ojpeg.c: Major upgrade from Scott. Details in bug 156.
<li> libtiff/tif_open.c: Pointers to custom procedures
in TIFFClientOpen() are checked to be not NULL-pointers.
<li> libtiff/tif_lzw.c: Assertions in LZWDecode and LZWDecodeCompat
replaced by warnings. Now libtiff should read corrupted LZW-compressed
files by skipping bad strips as per bug 100.
<li> libtiff/: tif_dirwrite.c, tif_write.c, tiffio.h:
<a href=./man/TIFFWriteDirectory.3t.html>TIFFCheckpointDirectory()</a>
routine added as per bug 124. The
<a href=./man/TIFFWriteDirectory.3t.html>TIFFWriteDirectory</a>
man page discusses this new function as well as the related
<a href=./man/TIFFWriteDirectory.3t.html>TIFFRewriteDirectory()</a>.
<li> libtiff/: tif_codec.c, tif_compress.c, tiffiop.h, tif_getimage.c:
Introduced
additional members tif->tif_decodestatus and tif->tif_encodestatus
for correct handling of unconfigured codecs (we should not try to read
data or to define data size without correct codecs). See bug 119.
<li> tif_dirread.c: avoid div-by-zero if rowbytes is zero in chop func as
per bug 111.
<li> libtiff/: tiff.h, tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c,
tif_dirwrite.c: Dwight Kelly added get/put code for new tag XMLPACKET as
defined in Adobe XMP Technote. Added missing INKSET tag value from TIFF 6.0
spec INKSET_MULTIINK (=2). Added missing tags from Adobe TIFF technotes:
CLIPPATH, XCLIPPATHUNITS, YCLIPPATHUNITS, OPIIMAGEID, OPIPROXY and
INDEXED. Added PHOTOMETRIC tag value from TIFF technote 4 ICCLAB (=9).
<li> libtiff/tif_getimage.c: Additional check for supported codecs added in
TIFFRGBAImageOK, TIFFReadRGBAImage, TIFFReadRGBAStrip and TIFFReadRGBATile now
use TIFFRGBAImageOK before reading a per bug 110.
<li> libtiff/: tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c,
tif_dirwrite.c: Added routine
<a href=./man/TIFFDataWidth.3t.html>TIFFDataWidth</a> for determining
TIFFDataType sizes instead of working with tiffDataWidth array
directly as per bug 109.
<li>libtiff/: tif_dirinfo.c, tif_dirwrite.c: Added possibility to
read broken TIFFs with LONG type used for TIFFTAG_COMPRESSION,
TIFFTAG_BITSPERSAMPLE, TIFFTAG_PHOTOMETRIC as per bug 99.
<li> libtiff/{tiff.h,tif_fax3.c}: Add support for __arch64__ as per bug 94.
<li> libtiff/tif_read.c: Fixed TIFFReadEncodedStrip() to fail if the
decodestrip function returns anything not greater than zero as per bug 97.
<li> libtiff/tif_jpeg.c: fixed computation of segment_width for
tiles files to avoid error about it not matching the
cinfo.d.image_width values ("JPEGPreDecode: Improper JPEG strip/tile
size.") for ITIFF files. Apparently the problem was incorporated since
3.5.5, presumably during the OJPEG/JPEG work recently.
<li> libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1
(defined in tiffconf.h - 1 by default) then the RGBA interface
will assume that a fourth extra sample is ASSOCALPHA if the
EXTRASAMPLE value isn't set for it. This changes the behaviour of
the library, but makes it work better with RGBA files produced by
lots of applications that don't mark the alpha values properly.
As per bugs 93 and 65.
<li> libtiff/tif_jpeg.c: allow jpeg data stream sampling values to
override those from tiff directory. This makes this work with
ImageGear generated files.

<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
<UL>
<li> libtiff/{tif_color.c, tif_getimage.c, tiffio.h}: Added support
for ReferenceBlackWhite tag handling when converted from YCbCr color space as
per bug 120.
<li> libtiff/{tif_getimage.c, tif_aux.c}: Read WhitePoint tag from the
file and properly use it for CIE Lab 1976 to RGB transform.
<li> libtiff/{tif_getimage.c, tiffio.h}: Finally resolved problems with
orientation handling. TIFFRGBAImage interface now properly supports all
possible orientations, i.e. images will be flipped both in horizontal and
vertical directions if required. 'Known bugs' section now removed from the
appropriate manual pages.
<li> libtiff/tif_luv.c: Fixed bug in 48-bit to 24-bit conversion routine,
reported by Antonio Scuri.
<li> libtiff/{tiffio.h, tif_codec.c}: Added new function
TIFFIsCODECConfigured(), suggested by Ross Finlayson.
<li> libtiff/tif_ojpeg.c: TIFFVGetField() function now can properly extract
the fields from the OJPEG files. Patch supplied by Ross Finlayson.
<li> libtiff/tif_dir.h: _TIFFFindOrRegisterdInfo declaration replaced
with _TIFFFindOrRegisterFieldInfo as reported by Ross Finlayson.
<li> libtiff/tif_dirinfo.c: Implemented binary search in _TIFFMergeFieldInfo().
Patch supplied by Ross Finlayson.
<li> tif_dirread.c: do not mark all anonymously defined tags to be IGNOREd (as
it was done in 3.6.0).
<li> libtiff/{tiff.h, tif_dirinfo.c}: Added support for IFD (13) datatype,
intruduced in "Adobe PageMaker TIFF Technical Notes".
<li> libtiff/{tif_color.c, tif_getimage.c, tiffio.h}: New color space
conversion code: CIE L*a*b* 1976 images now supported by the TIFFRGBAImage
interface. YCbCr to RGB conversion code also moved there and now has
<a href="./man/TIFFcolor.3t.html">publicly available interface</a>. These
routines currently used in TIFFRGBAImage interface only and not supported in
other libtiff tools yet. So if you want, for example, to convert CIE Lab image
into PostScript file you should do it in two steps: chnge colorspace to RGB
using <a href="./man/tiff2rgba.1.html">tiff2rgba</a> utility abd then process
it with the <a href="./man/tiff2ps.1.html">tiff2ps</a>.
<li> libtiff/tif_tile.c: Remove spurious use of "s" (sample) in the
planarconfig_contig case in TIFFComputeTile() as per bug 387
<li> libtiff/tiffiop.h: New macros: TIFFmax and TIFFmin.

<A NAME="highlights"><B><FONT SIZE=+3>M</FONT>AJOR CHANGES:</B></A>
<UL>
<li> New <b>tiffcrop</b> utility contributed by Richard Nolde.
<b>tiffcrop</b> does the same as <b>tiffcp</b>, but also can crop,
extract, rotate and mirror images.
<li> tif_jbig.c: Added support for JBIG compression scheme
(34661 code), contributed by Lee Howard.
<li> Totally new implementation of OJPEG module from
Joris Van Damme. No need to patch libjpeg anymore. Many OJPEG files
should be supported now that was not supported previously.
</UL>
<P><HR WIDTH=65% ALIGN=left>
<!--------------------------------------------------------------------------->
<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
<UL>
<li> tif_config.wince.h, tiffconf.wince.h, tif_wince.c: WinCE-specific
compatibility stuff from Mateusz Loskot.
<li> Rename config.h.vc and tif_config.h.vc to config.vc.h and
tif_config.vc.h for easier identification by folks using an IDE.
<li> configure, configure.ac: OJPEG support enabled by default (i.e.,
whe the conformant JPEG support enabled).
<li> README.vms, Makefile.am, configure.com, libtiff/{Makefile.am,
tif_config.h-vms, tif_stream.cxx, tif_vms.c, tiffconf.h-vms}:
Added support for OpenVMS by Alexey Chupahin.
<li> nmake.opt: use /EHsc for VS2005 compatibility. Also define
_CRT_SECURE_NO_DEPRECATE to avoid noise on VS2005.
</UL>
<P><HR WIDTH=65% ALIGN=left>
<!--------------------------------------------------------------------------->
<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
<UL>
<li> tif_dirinfo.c (_TIFFFindFieldInfo): Don't attempt to
bsearch() on a NULL fieldinfo list.
(_TIFFFindFieldInfoByName): Don't attempt to lfind() on a NULL
fieldinfo list.
<li> tif_jpeg.c: Changed JPEGInitializeLibJPEG() so that it
will convert from decompressor to compressor or compress to decompress
if required by the force arguments. This works around a problem in
where the JPEGFixupTestSubsampling() may cause a decompressor to
be setup on a directory when later a compressor is required with the
force flag set. Occurs with the addtiffo program for instance.
<li> tif_dirwrite.c: Fixed swapping of byte arrays stored
in-place in tag offsets as per bug
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1363">
http://bugzilla.remotesensing.org/show_bug.cgi?id=1363</a>
<li> tif_getimage.c: workaround for 'Fractional scanline' error
reading OJPEG images with rowsperstrip that is not a multiple of
vertical subsampling factor. This bug is mentioned in
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1390">
http://bugzilla.remotesensing.org/show_bug.cgi?id=1390</a> and
<a href="http://www.asmail.be/msg0054766825.html">
http://www.asmail.be/msg0054766825.html</a>
<li> tif_dirread.c: Added special function to handle
SubjectDistance EXIF tag as per bug
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1362">
http://bugzilla.remotesensing.org/show_bug.cgi?id=1362</a>
<li> tif_dirread.c, tif_read.c: Type of the byte counters
changed from tsize_t to uint32 to be able to work with data arrays
larger than 2GB. Fixes bug
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=890">
http://bugzilla.remotesensing.org/show_bug.cgi?id=89</a>
Idea submitted by Matt Hancher.
<li> tif_dir.c: Workaround for incorrect TIFFs with
ExtraSamples == 999 produced by Corel Draw. As per bug
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1490">
http://bugzilla.remotesensing.org/show_bug.cgi?id=1490</a>
<li> tif_write.c: TIFFAppendToStrip() - clear sorted flag if
we move a strip.
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1359">
http://bugzilla.remotesensing.org/show_bug.cgi?id=1359</a>
<li> tif_fax3.c: Save the state of printdir codec dependent method.
<li> tif_jpeg.c: Save the state of printdir codec dependent method
as per bug
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1273">
http://bugzilla.remotesensing.org/show_bug.cgi?id=1273</a>
<li> tif_win32.c: Fixed problem with offset value manipulation
as per bug
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1322">
http://bugzilla.remotesensing.org/show_bug.cgi?id=1322</a>
<li> tif_fax3.c, tif_next.c, tif_pixarlog.c: Fixed multiple
vulnerabilities, as per Gentoo bug ():
<a href="http://bugs.gentoo.org/show_bug.cgi?id=142383">
http://bugs.gentoo.org/show_bug.cgi?id=142383</a>
<li> tif_lzw.c, tif_zip.c: Fixed problems with mixing
encoding and decoding on the same read-write TIFF handle. The LZW
code can now maintain encode and decode state at the same time. The
ZIP code will switch back and forth as needed.
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=757">
http://bugzilla.remotesensing.org/show_bug.cgi?id=757</a>
<li> tif_msdos.c: Avoid handle leak for failed opens.
c/o Thierry Pierron
<li> tif_dirwrite.c: take care not to flush out buffer of strip/tile
data in _TIFFWriteDirectory if TIFF_BEENWRITING not set. Relates
to bug report by Peng Gao with black strip at bottom of images.
<li> tif_dirwrite.c: make sure to use uint32 for wordcount in
TIFFWriteNormanTag if writecount is VARIABLE2 for ASCII fields.
It already seems to have been done for other field types. Needed
for "tiffset" on files with geotiff ascii text.
<li> tif_dirinfo.c: Added missed EXIF tag ColorSpace (40961).
<li> tif_dirread.c: Move IFD fetching code in the separate
function TIFFFetchDirectory() avoiding code duplication in
TIFFReadDirectory() and TIFFReadCustomDirectory().
<li>tif_readdir.c: Added case in EstimateStripByteCounts() for tiled
files. Modified TIFFReadDirectory() to not invoke
EstimateStripByteCounts() for case where entry 0 and 1 are unequal but
one of them is zero.
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1204">
http://bugzilla.remotesensing.org/show_bug.cgi?id=1204</a>
<li> tif_open.c, tif_dirread.c, tiffiop.h: Move IFD looping
checking code in the separate function TIFFCheckDirOffset().
<li> tif_aux.c: Added _TIFFCheckRealloc() function.
<li> tif_fax3.c: Fixed problems in fax decoder as per bug
<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1194">
http://bugzilla.remotesensing.org/show_bug.cgi?id=1194</a>
<li> tif_jbig.c: Added support for JBIG compression scheme

http://bugzilla.remotesensing.org/show_bug.cgi?id=896</a>
<li> tif_getimage.c: Added support for planarconfig separate
non-subsampled YCbCr (i.e. separate YCbCr with subsampling [1,1]).
<li> tif_getimage.c: Revision of all RGB(A) put routines:
<ul>
<li> Conversion of unassociated alpha to associated alpha
now done with more performant LUT, and calculation more
correct.
<li> Conversion of 16bit data to 8bit data now done with
more performant LUT, and calculation more correct
<li> Bugfix of handling of 16bit RGB with unassociated alpha
</ul>
<li> tif_ojpeg.c: totally new implementation
<li> tif_getimage.c: removed TIFFTAG_JPEGCOLORMODE handling
of OJPEG images in favor of tif_getimage.c native handling of
YCbCr and desubsampling.
<li> tif_jpeg.c: JPEGVSetField() so that altering the photometric
interpretation causes the "upsampled" flag to be recomputed. Fixes
peculiar bug where photometric flag had to be set before jpegcolormode
flag.

BigTIFF support changes:
<UL>
<LI>The options parameter in the TIFFOpen and TIFFClientOpen funcs has
been extended. When creating new files, you can add option '4' to
specify you want to create a ClassicTIFF file, though that is the
default and the option is not strictly necessary. (As such, old
calling code will continue to function and create ClassicTIFF files.)
Or you can add option '8' to specify you want to create a BigTIFF file
instead. This new option is also reflected in some of the tools we
already upgraded. For instance, you can use the -8 option on tiffcp to
have tiffcp produce BigTIFF files instead of the default ClassicTIFF.
(Whilst on additional option is provided for version selection when
creating new files, no such option is necessary when reading TIFF
files. LibTiff reads ClassicTIFF and BigTIFF both, and the application
does not need to be aware which TIFF version an opened file is.)
<LI>Although the tag count in BigTIFF is 64bit, we restricted the
count in the implementation to a much more reasonable size. This is
necessary in current implementation, because all tag data gets read
automatically in the IFD reading stage, so if there's half a dozen
private tags with multiple gigabytes of data that causes considerable
overhead even if the application level is never interested in these
tags. Our choice to ignore tags with data longer then a certain sanity
value is much needed as things stand. We also recommend to step away
from writing tiles that are 8 kilobyte in their uncompressed form, or
writing single-line strips, in really big files, resulting in mega's
of tiles or strips. It's much more efficient to choose bigger tile or
strip sizes, up to several megabyte if needed, and have a few kilo of
tiles or strips instead.
<LI>Although it's rare, some application code does directly access
file offsets. Some of these are automatically upgraded because they
used the toff_t type, others need to be aware that the datatype
changed and need to start using toff_t or uint64. This impacts access
to tags like the EXIF IFD tag, for example, or the SubIfds tag, or to
StripOffsets or TileOffsets, the return type of functions like
TIFFCurrentDirOffset, and a parameter type to functions like
TIFFSetSubDirectory.
<LI>Although it's rare, some application code does use structures
like TIFFHeader or TIFFDirEntry that used to be an exact binary
representation of TIFF structures. These need to change. The old
TIFFHeader structure is replaced by the new TIFFHeaderClassic,
TIFFHeaderBig, and TIFFHeaderCommon structures that are an exact
binary representation of the ClassicTIFF and BigTIFF header, and of
the part that is common to both. There is no new equivalent for the
old TIFFDirEntry structure (or more precisely, there is still a
TIFFDirEntry structure, but it is changed, moved to library-private
definition, and no longer an exact binary representation of the tag
structure of either TIFF version).
<LI>Sizer functions, like TIFFTileSize or TIFFScanlineSize and the
like, return a tmsize_t value (tmsize_t is defined as int32 on 32bit
machines, and int64 on 64bit machines, and as such it is meant to
represent signed memory sizes). This is because we figure 98% of the
calling code uses the return value as sizes in allocations and the
like. So, any overflow that is theoretically possible with BigTIFF
when LibTiff is running on a 32bit system, is best detected inside the
sizer functions and it is best to return a type that makes sense as a
memory size. If your calling code is the exception and is interested
in actual file size, you best use the newer TIFFTileSize64 or
TIFFScanlineSize64 function that returns an uint64 type.
<LI>These TIFF tags require a 64-bit type as an argument in
libtiff 4.0.0:
<UL>
<LI> TIFFTAG_FREEBYTECOUNTS
<LI> TIFFTAG_FREEOFFSETS
<LI> TIFFTAG_STRIPBYTECOUNTS
<LI> TIFFTAG_STRIPOFFSETS
<LI> TIFFTAG_TILEBYTECOUNTS
<LI> TIFFTAG_TILEOFFSETS
</UL>
</UL>
Other important backward incompatible changes in the public API:
<UL>
<LI> TIFFRewriteField() renamed into _TIFFRewriteField() and moved out
from the public interface (from tiffio.h to tiffiop.h). Type of its
'count' parameter changed from uint32 to tmsize_t.
<LI> TIFFMergeFieldInfo() returns non-void result now. It returns 0
if successful and -1 if failed. Though this is now obsoleted function
and should not be used in new programs. Use the new tag extension
scheme instead.
<LI> TIFFFieldWithTag() and TIFFFieldWithName() functions now return
pointer to TIFFField constant object instead of TIFFFieldInfo.
<LI> TIFFReassignTagToIgnore() function and TIFFIgnoreSense enumeration
have been removed. They was unused and never been used properly.
Should be unneeded for high-level applications.
<LI> TIFFTagValue structure removed from the public tiffio.h
to private tif_dir.h and not accessible anymore. It should be unneeded
for high-level applications.

<P><A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A></P>
<UL>
<LI>Updated autotools: Autoconf 2.68, Automake 1.11.1, libtool
2.4.
<LI>Enabled support for Automake silent build rules
(--enable-silent-rules or 'make V=0')
<LI>Enabled support for Automake colorized and parallel tests.
<LI>Added detection of 64-bit integer types since libtiff 4.0
requires use of 64-bit signed and unsigned integer types.
<LI>Libtiff now provides a more comprehensive test suite with
over 72 tests, which may be executed on Unix-like systems, or
under Microsoft Windows using MinGW/MSYS or Cygwin.
<LI>--disable-lzma configure option to disable use of liblzma.
<LI>--enable-defer-strile-load configure option to enable
experimental deferred strip/tile offset/size loading. May
cause some extremely sophisticated uses of libtiff to fail.
<LI>--enable-chunky-strip-read configure option to enable
experimental enable reading large strips in chunks in
TIFFReadScanline().
<LI>Now always uses WIN32 native I/O functions for Microsoft
Windows except for under Cygwin.
<LI>Now provides a pkg-config support file (libtiff-4.pc).

<UL>
<LI>Patches/fixes made to stable libtiff (v3.9.X) are also
applied to 4.0.0. There are too many to list here. See the
distribution ChangeLog for a detailed change list.
<LI>There is considerable change in some files like
tif_dirread and tif_dirwrite. These changes don't impact
backwards compatibility, they are mostly a clean rewrite that
does allow BigTIFF support as well as somewhat more robust
reading of the unexpected already and will also serve future
API extension but does not impact current API or functionality
in a negative way that you need to know about.
<LI>Although there is still a functional definition for types
like toff_t (file offset), tstrip_t (strip index number), etc,
we recommend against using these in newer code. We have
learned that it is next to impossible to use these
consistently and make real abstraction of the binary format of
these types. Instead, at a certain level we always end up
doing casts anyway, and taking the exact binary format into
account, so these types are nothing but dangerously misleading
and obfuscating. You do not need to update calling code that
uses them, as 99.9% of such code will continue to work. But we
recommend against using them in newer calling code, and we
started replacing them with binary clear types like uint16,
uint32 and such in the library.
<LI>We do use and will continue to use one functional type
that is an exception to the above rule, being tmsize_t. This
is a signed memory size type, i.e. it is int32 on 32bit
machines, or int64 on 64bit machines.
<LI>Optionally support LZMA compression via TIFF tag 34925.
Tiffcp supports compression levels similar to "-c lzma:p1" or
"-c zip:p9 for setting the LZMA compression parameters.
<LI>Optionally defer the load of strip/tile offset and size
tags for optimized scanning of directories. Enabled with the
--enable-defer-strile-load configure option (DEFER_STRILE_LOAD
#define in tif_config.h).
<LI>Optionally enable experimental support for reading big
strips in chunks. Enabled with the --enable-chunky-strip-read
configure option.

<li> TIFFCheckDirOffset(): avoid uint16 overflow
when reading more than 65535 directories, and effectively error out when
eaching that limit.
<li> TIFFNumberOfDirectories(): generate error in case of directory count
overflow.
<li> TIFFAdvanceDirectory(): If nextdir is found to
be defective, then set it to zero before returning error in order
to terminate processing of truncated TIFF.
<li> JPEG-in-TIFF: recognize SOF2, SOF9 and SOF10
markers to avoid emitting a warning. Fix for compatibility with mozjpeg library.
Note: the default settings of mozjpeg will produce progressive scans, which
is forbidden by the TechNote.
<li> JPEG-in-TIFF: Fix regression introduced in 3.9.3/4.0.0 that caused
all tiles/strips to include quantization tables even when the jpegtablesmode
had the JPEGTABLESMODE_QUANT bit set.
Also add explicit removal of Huffman tables when jpegtablesmode has the
JPEGTABLESMODE_HUFF bit set, which avoids Huffman tables to be emitted in the
first tile/strip (only useful in update scenarios. create-only was
fine)
<li> JPEG-in-TIFF: fix segfault in JPEGFixupTagsSubsampling() on
corrupted image where tif->tif_dir.td_stripoffset == NULL.
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2471">#2471</a>)
<li> NeXT codec: add new tests to check that we don't read outside of
the compressed input stream buffer.
<li> NeXT codec: check that BitsPerSample = 2. Fixes
<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2487">#2487</a> (CVE-2014-8129)
<li> NeXT codec: in the "run mode", use tilewidth for tiled images
instead of imagewidth to avoid crash
<li> tif_getimage.c: in OJPEG case, fix checks on strile width/height
in the putcontig8bitYCbCr42tile, putcontig8bitYCbCr41tile and
putcontig8bitYCbCr21tile cases.
<li> in TIFFDefaultDirectory(), reset any already existing
extented tags installed by user code through the extender mechaninm before
calling the extender callback (GDAL #5054)
<li> Fix warnings about unused parameters.
<li> Fix various typos in comments found by Debian lintian tool (GDAL #5756)
<li> tif_getimage.c: avoid divide by zero on invalid YCbCr subsampling.
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2235">#2235</a>)
<li> tif_dirread.c: In EstimateStripByteCounts(), check return code
of _TIFFFillStriles(). This solves crashing bug on corrupted
images generated by afl.
<li>tif_read.c: fix several invalid comparisons of a uint64 value with
<= 0 by casting it to int64 first. This solves crashing bug on corrupted
images generated by afl.
<li>TIFFSetField(): refuse to set negative values for
TIFFTAG_XRESOLUTION and TIFFTAG_YRESOLUTION that cause asserts when writing
the directory
<li>TIFFReadDirectory(): refuse to read ColorMap or
TransferFunction if BitsPerSample has not yet been read, otherwise reading
it later will cause user code to crash if BitsPerSample > 1
<li> TIFFRGBAImageOK(): return FALSE if LOGLUV with
SamplesPerPixel != 3, or if CIELAB with SamplesPerPixel != 3 or BitsPerSample != 8
<li> tif_config.vc.h: no longer use "#define snprintf _snprintf" with
Visual Studio 2015 aka VC 14 aka MSVC 1900
<li> LZW codec: prevent potential null dereference of sp->dec_codetab in LZWPreDecode
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2459">#2459</a>)
<li> TIFFReadBufferSetup(): avoid passing -1 size
to TIFFmalloc() if passed user buffer size is 0
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2459">#2459</a>)
<li> TIFFReadDirEntryOutputErr(): Incorrect
count for tag should be a warning rather than an error since
errors terminate processing.
<li> tif_dirinfo.c (TIFFField) : Fix data type for TIFFTAG_GLOBALPARAMETERSIFD tag.
<li> Add definitions for TIFF/EP CFARepeatPatternDim and CFAPattern tags
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2457">#2457</a>)
<li> tif_codec.c, tif_dirinfo.c: Enlarge some fixed-size buffers that weren't
large enough, and eliminate substantially all uses of sprintf(buf,
...) in favor of using snprintf(buf, sizeof(buf), ...)
<li> configure.ac: Improve pkg-config static linking by adding -lm to Libs.private when needed.
<li> tif_write.c: tmsize_t related casting warning fixed for
64bit linux.
<li> tif_read.c: uint64/tmsize_t change for MSVC warnings.
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2427">#2427</a>)
<li> Fix TIFFPrintDirectory's handling of
field_passcount fields: it had the TIFF_VARIABLE and
TIFF_VARIABLE2 cases backwards.
<li> PixarLog codec: Improve previous patch for CVE-2012-4447
(to enlarge tbuf for possible partial stride at end) so that
overflow in the integer addition is detected.
<li>tif_{unix,vms,win32}.c (_TIFFmalloc): ANSI C does not
require malloc() to return NULL pointer if requested allocation
size is zero. Assure that _TIFFmalloc does.
<li>tif_zip.c: Avoid crash on NULL error messages.

<li> tiff2pdf: Rewrite JPEG marker parsing in
t2p_process_jpeg_strip to be at least marginally competent. The
approach is still fundamentally flawed, but at least now it won't
stomp all over memory when given bogus input. Fixes CVE-2013-1960.

<li> tiffcp: fix crash when converting YCbCr JPEG-compressed to none.
(<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2480">#2480</a>)
<li> bmp2tiff: fix crash due to int overflow related to input BMP dimensions
<li> tiffcrop: fix crash due to invalid TileWidth/TileHeight
<li> tiffcrop: fix segfault if bad value passed to -Z option

<li> gif2tiff: fix possible OOB write. (<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2452">#2452</a>, CVE-2013-4244)
<li> gif2tiff: Be more careful about corrupt or hostile input files (<a href="http://bugzilla.maptools.org/show_bug.cgi?id=2450">#2450</a>, CVE-2013-4231)
<li> tiff2rgba: fix usage message in that zip was wrongly described
<li> tiffinfo: Default various values fetched with TIFFGetField() to avoid being uninitialized.
<li> tiff2ps: Fix bug in auto rotate option code.
<li> ppm2tiff: avoid zero size buffer vulnerability (CVE-2012-4564).
check the linebytes calculation too, get the max() calculation
straight, avoid redundant error messages, check for malloc
failure.

Enlarge some fixed-size buffers that weren't
large enough, and eliminate substantially all uses of sprintf(buf,
...) in favor of using snprintf(buf, sizeof(buf), ...), so as to
protect against overflow of fixed-size buffers. This responds in
particular to CVE-2013-1961 concerning overflow in tiff2pdf.c's

<LI> tiffiop.h:
<UL>
<LI> Macros added to use 64-bit equivalents for all standard I/O
and POSIX APIs used by libtiff and its tools which are limited
to 2GB in Windows builds. Note that these 64-bit equivalents
were introduced by the CRT provided with Visual Studio 2005 and
if the necessary CRT is not installed on the target computer,
the program will not run. The wrapper macros will not be
activated unless the definition _MSC_VER is at least 1400 or
__MSVCRT_VERSION__ is at least 0x800.
</UL>
<LI> tif_unix.c:
<UL>
<LI> Updated to support large files under Microsoft Windows.
This makes tif_unix.c a completely viable candidate for use
under Windows (in spite of its name) if the CRT is modern
enough. Please note that tif_win32.c already supported large
files, but only 'tiffinfo' and 'tiffdump' made any provision to
support large files under Windows.
<LI> _tiffReadProc() and _tiffWriteProc() are modified to chunk
I/O to a maximum size of 2GB for extremely large I/O
requests. This surmounts limitations in the Microsoft Windows
read() and write() APIs (which are limited to the range of a
32-bit 'int'), and may avoid poor behavior with extremely large
I/O requests on other systems.

<UL>
<LI> The libtiff tools bmp2tiff, gif2tiff, ras2tiff, sgi2tiff,
sgisv, and ycbcr are completely removed from the distribution.
These tools were written in the late 1980s and early 1990s for
test and demonstration purposes. In some cases the tools were
never updated to support updates to the file format, or the
file formats are now rarely used. In all cases these tools
increased the libtiff security and maintenance exposure beyond
the value offered by the tool.

<LI> libtiff/tif_dirread.c: in TIFFFetchNormalTag(), do not
dereference NULL pointer when values of tags with
TIFF_SETGET_C16_ASCII / TIFF_SETGET_C32_ASCII access are
0-byte arrays. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2593 (regression
introduced by previous fix done on 2016-11-11 for
CVE-2016-9297). Reported by Henri Salo. Assigned as
CVE-2016-9448
<LI> libtiff/tif_aux.c: fix crash in TIFFVGetFieldDefaulted() when
requesting Predictor tag and that the zip/lzw codec is not
configured. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2591
<LI> libtiff/tif_dirread.c: in TIFFFetchNormalTag(), make sure
that values of tags with TIFF_SETGET_C16_ASCII /
TIFF_SETGET_C32_ASCII access are null terminated, to avoid
potential read outside buffer in _TIFFPrintField(). Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2590
<LI> libtiff/tif_dirread.c: reject images with OJPEG compression
that have no TileOffsets/StripOffsets tag, when OJPEG
compression is disabled. Prevent null pointer dereference in
TIFFReadRawStrip1() and other functions that expect
td_stripbytecount to be non NULL. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2585
<LI> libtiff/tif_strip.c: make TIFFNumberOfStrips() return the
td->td_nstrips value when it is non-zero, instead of
recomputing it. This is needed in TIFF_STRIPCHOP mode where
td_nstrips is modified. Fixes a read outsize of array in
tiffsplit (or other utilities using TIFFNumberOfStrips()).
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2587
(CVE-2016-9273)
<LI> libtiff/tif_predict.h, libtiff/tif_predict.c: Replace
assertions by runtime checks to avoid assertions in debug
mode, or buffer overflows in release mode. Can happen when
dealing with unusual tile size like YCbCr with
subsampling. Reported as MSVR 35105 by Axel Souchet & Vishal
Chauhan from the MSRC Vulnerabilities & Mitigations
<LI> libtiff/tif_dir.c: discard values of SMinSampleValue and
SMaxSampleValue when they have been read and the value of
SamplesPerPixel is changed afterwards (like when reading a
OJPEG compressed image with a missing SamplesPerPixel tag, and
whose photometric is RGB or YCbCr, forcing SamplesPerPixel
being 3). Otherwise when rewriting the directory (for example
with tiffset, we will expect 3 values whereas the array had
been allocated with just one), thus causing a out of bound
read access. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2500
(CVE-2014-8127, duplicate: CVE-2016-3658)
<LI> libtiff/tif_dirwrite.c: avoid null pointer dereference on
td_stripoffset when writing directory, if FIELD_STRIPOFFSETS
was artificially set for a hack case in OJPEG case. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2500
(CVE-2014-8127, duplicate: CVE-2016-3658)
<LI> libtiff/tif_getimage.c (TIFFRGBAImageOK): Reject attempts to
read floating point images.
<LI> libtiff/tif_predict.c (PredictorSetup): Enforce
bits-per-sample requirements of floating point predictor (3).
Fixes CVE-2016-3622 "Divide By Zero in the tiff2rgba tool."
<LI> libtiff/tif_pixarlog.c: fix out-of-bounds write vulnerabilities
in heap allocated buffers. Reported as MSVR 35094. Discovered by
Axel Souchet and Vishal Chauhan from the MSRC Vulnerabilities &
Mitigations team.
<LI> libtiff/tif_write.c: fix issue in error code path of
TIFFFlushData1() that didn't reset the tif_rawcc and tif_rawcp
members. I'm not completely sure if that could happen in
practice outside of the odd behaviour of t2p_seekproc() of
tiff2pdf). The report points that a better fix could be to
check the return value of TIFFFlushData1() in places where it
isn't done currently, but it seems this patch is enough.
Reported as MSVR 35095. Discovered by Axel Souchet & Vishal
Chauhan & Suha Can from the MSRC Vulnerabilities & Mitigations
team.
<LI> libtiff/tif_pixarlog.c: Fix write buffer overflow in
PixarLogEncode if more input samples are provided than
expected by PixarLogSetupEncode. Idea based on
libtiff-CVE-2016-3990.patch from
libtiff-4.0.3-25.el7_2.src.rpm by Nikola Forro, but with
different and simpler check. (bugzilla #2544)
<LI> libtiff/tif_read.c: Fix out-of-bounds read on memory-mapped
files in TIFFReadRawStrip1() and TIFFReadRawTile1() when
stripoffset is beyond tmsize_t max value (reported by Mathias
Svensson)
<LI> libtiff/tif_read.c: make TIFFReadEncodedStrip() and
TIFFReadEncodedTile() directly use user provided buffer when
no compression (and other conditions) to save a memcpy()
<LI> libtiff/tif_write.c: make TIFFWriteEncodedStrip() and
TIFFWriteEncodedTile() directly use user provided buffer when
no compression to save a memcpy().
<LI> libtiff/tif_luv.c: validate that for COMPRESSION_SGILOG and
PHOTOMETRIC_LOGL, there is only one sample per pixel. Avoid
potential invalid memory write on corrupted/unexpected images
when using the TIFFRGBAImageBegin() interface (reported by
Clay Wood)
<LI> libtiff/tif_pixarlog.c: fix potential buffer write overrun in
PixarLogDecode() on corrupted/unexpected images (reported by
Mathias Svensson) (CVE-2016-5875)
<LI> libtiff/libtiff.def: Added _TIFFMultiply32 and
_TIFFMultiply64 to libtiff.def
<LI> libtiff/tif_config.vc.h (HAVE_SNPRINTF): Add a '1' to the
HAVE_SNPRINTF definition.
<LI> libtiff/tif_config.vc.h (HAVE_SNPRINTF): Applied patch by
Edward Lam to define HAVE_SNPRINTF for Visual Studio 2015.
<LI> libtiff/tif_dirread.c: when compiled with DEFER_STRILE_LOAD,
fix regression, introduced on 2014-12-23, when reading a
one-strip file without a StripByteCounts tag. GDAL #6490
<LI> libtiff/*: upstream typo fixes (mostly contributed by Kurt
Schwehr) coming from GDAL internal libtiff
<LI> libtiff/tif_fax3.h: make Param member of TIFFFaxTabEnt
structure a uint16 to reduce size of the binary.
<LI> libtiff/tif_read.c, tif_dirread.c: fix indentation issues
raised by GCC 6 -Wmisleading-indentation
<LI> libtiff/tif_pixarlog.c: avoid zlib error messages to pass a
NULL string to %s formatter, which is undefined behaviour in
sprintf().
<LI> libtiff/tif_next.c: fix potential out-of-bound write in NeXTDecode()
triggered by http://lcamtuf.coredump.cx/afl/vulns/libtiff5.tif
(bugzilla #2508)
<LI> libtiff/tif_luv.c: fix potential out-of-bound writes in
decode functions in non debug builds by replacing assert()s by
regular if checks (bugzilla #2522). Fix potential
out-of-bound reads in case of short input data.
<LI> libtiff/tif_getimage.c: fix out-of-bound reads in
TIFFRGBAImage interface in case of unsupported values of
SamplesPerPixel/ExtraSamples for LogLUV / CIELab. Add explicit
call to TIFFRGBAImageOK() in TIFFRGBAImageBegin(). Fix
CVE-2015-8665 reported by limingxing and CVE-2015-8683
reported by zzf of Alibaba.
<LI> libtiff/tif_dirread.c: workaround false positive warning of
Clang Static Analyzer about null pointer dereference in
TIFFCheckDirOffset().
<LI> libtiff/tif_fax3.c: remove dead assignment in
Fax3PutEOLgdal(). Found by Clang Static Analyzer
<LI> libtiff/tif_dirwrite.c: fix truncation to 32 bit of file
offsets in TIFFLinkDirectory() and TIFFWriteDirectorySec()
when aligning directory offsets on a even offset (affects
BigTIFF). This was a regression of the changeset of
2015-10-19.
<LI> libtiff/tif_write.c: TIFFWriteEncodedStrip() and
TIFFWriteEncodedTile() should return -1 in case of failure of
tif_encodestrip() as documented
<LI> libtiff/tif_dumpmode.c: DumpModeEncode() should return 0 in
case of failure so that the above mentionned functions detect
the error.
<LI> libtiff/*.c: fix MSVC warnings related to cast shortening and
assignment within conditional expression
<LI> libtiff/*.c: fix clang -Wshorten-64-to-32 warnings
<LI> libtiff/tif_dirread.c: prevent reading ColorMap or
TransferFunction if BitsPerPixel > 24, so as to avoid huge
memory allocation and file read attempts
<LI> libtiff/tif_dirread.c: remove duplicated assignment (reported
by Clang static analyzer)
<LI> libtiff/tif_dir.c, libtiff/tif_dirinfo.c,
libtiff/tif_compress.c, libtiff/tif_jpeg_12.c: suppress
warnings about 'no previous declaration/prototype'
<LI> libtiff/tiffiop.h, libtiff/tif_dirwrite.c: suffix constants
by U to fix 'warning: negative integer implicitly converted to
unsigned type' warning (part of -Wconversion)
<LI> libtiff/tif_dir.c, libtiff/tif_dirread.c,
libtiff/tif_getimage.c, libtiff/tif_print.c: fix -Wshadow
warnings (only in libtiff/)

<UL>
<LI> tools/Makefile.am: The libtiff tools bmp2tiff, gif2tiff,
ras2tiff, sgi2tiff, sgisv, and ycbcr are completely removed
from the distribution. The libtiff tools rgb2ycbcr and

as TALOS-CAN-0187 / CVE-2016-5652. Also prevents writing 2
extra uninitialized bytes to the file stream.
<LI> tools/tiffcp.c: fix out-of-bounds write on tiled images with odd
tile width vs image width. Reported as MSVR 35103
by Axel Souchet and Vishal Chauhan from the MSRC Vulnerabilities &
Mitigations team.
<LI> tools/tiff2pdf.c: fix read -largely- outsize of buffer in
t2p_readwrite_pdf_image_tile(), causing crash, when reading a

one. Reported as MSVR 35101 by Axel Souchet and Vishal
Chauhan from the MSRC Vulnerabilities & Mitigations team.
<LI> tools/tiffcp.c: fix read of undefined variable in case of
missing required tags. Found on test case of MSVR 35100.
<LI> tools/tiffcrop.c: fix read of undefined buffer in
readContigStripsIntoBuffer() due to uint16 overflow. Probably
not a security issue but I can be wrong. Reported as MSVR
35100 by Axel Souchet from the MSRC Vulnerabilities &
Mitigations team.
<LI> tools/tiffcrop.c: fix various out-of-bounds write
vulnerabilities in heap or stack allocated buffers. Reported

avoid potential divide by zero. Fixes CVE-2016-3623 (bugzilla #2569)
<LI> tools/tiffcrop.c: Fix out-of-bounds write in loadImage().
From patch libtiff-CVE-2016-3991.patch from
libtiff-4.0.3-25.el7_2.src.rpm by Nikola Forro (bugzilla
#2543)
<LI> tools/tiff2rgba.c: Fix integer overflow in size of allocated
buffer, when -b mode is enabled, that could result in
out-of-bounds write. Based initially on patch
tiff-CVE-2016-3945.patch from libtiff-4.0.3-25.el7_2.src.rpm
by Nikola Forro, with correction for invalid tests that
rejected valid files. (bugzilla #2545)
<LI> tools/tiffcrop.c: Avoid access outside of stack allocated
array on a tiled separate TIFF with more than 8 samples per
pixel. Reported by Kaixiang Zhang of the Cloud Security Team,
Qihoo 360 (CVE-2016-5321 / CVE-2016-5323 , bugzilla #2558 /

<LI> libtiff/tif_getimage.c, libtiff/tif_open.c: add parenthesis
to fix cppcheck clarifyCalculation warnings *
libtiff/tif_predict.c, libtiff/tif_print.c: fix printf
unsigned vs signed formatting (cppcheck
invalidPrintfArgType_uint warnings)
<LI> libtiff/tif_read.c, libtiff/tiffiop.h: fix uint32 overflow in
TIFFReadEncodedStrip() that caused an integer division by
zero. Reported by Agostino Sarubbo. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2596
<LI> libtiff/tif_pixarlog.c, libtiff/tif_luv.c: fix heap-based
buffer overflow on generation of PixarLog / LUV compressed
files, with ColorMap, TransferFunction attached and nasty
plays with bitspersample. The fix for LUV has not been
tested, but suffers from the same kind of issue of PixarLog.
Reported by Agostino Sarubbo. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2604
<LI> libtiff/tif_strip.c: revert the change in
TIFFNumberOfStrips() done for
http://bugzilla.maptools.org/show_bug.cgi?id=2587 /
CVE-2016-9273 since the above change is a better fix that
makes it unnecessary.
<LI> libtiff/tif_dirread.c: modify ChopUpSingleUncompressedStrip()
to instanciate compute ntrips as
TIFFhowmany_32(td->td_imagelength, rowsperstrip), instead of a
logic based on the total size of data. Which is faulty is the
total size of data is not sufficient to fill the whole image,
and thus results in reading outside of the
StripByCounts/StripOffsets arrays when using
TIFFReadScanline(). Reported by Agostino Sarubbo. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2608.
<LI> libtiff/tif_ojpeg.c: make OJPEGDecode() early exit in case of
failure in OJPEGPreDecode(). This will avoid a divide by zero,
and potential other issues. Reported by Agostino Sarubbo.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2611
<LI> libtiff/tif_write.c: fix misleading indentation as warned by GCC.
<LI> libtiff/tif_fax3.h: revert change done on 2016-01-09 that
made Param member of TIFFFaxTabEnt structure a uint16 to
reduce size of the binary. It happens that the Hylafax
software uses the tables that follow this typedef
(TIFFFaxMainTable, TIFFFaxWhiteTable, TIFFFaxBlackTable),
although they are not in a public libtiff header. Raised by
Lee Howard. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2636
<LI> libtiff/tiffio.h, libtiff/tif_getimage.c: add
TIFFReadRGBAStripExt() and TIFFReadRGBATileExt() variants of
the functions without ext, with an extra argument to control
the stop_on_error behaviour.
<LI> libtiff/tif_getimage.c: fix potential memory leaks in error
code path of TIFFRGBAImageBegin(). Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2627
<LI> libtiff/tif_jpeg.c: increase libjpeg max memory usable to 10
MB instead of libjpeg 1MB default. This helps when creating
files with "big" tile, without using libjpeg temporary files.
Related to https://trac.osgeo.org/gdal/ticket/6757
<LI> libtiff/tif_jpeg.c: avoid integer division by zero in
JPEGSetupEncode() when horizontal or vertical sampling is set
to 0. Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2653
<LI> libtiff/tif_dirwrite.c: in
TIFFWriteDirectoryTagCheckedRational, replace assertion by
runtime check to error out if passed value is strictly
negative. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2535
<LI> libtiff/tif_dirread.c: avoid division by floating point 0 in
TIFFReadDirEntryCheckedRational() and
TIFFReadDirEntryCheckedSrational(), and return 0 in that case
(instead of infinity as before presumably) Apparently some
sanitizers do not like those divisions by zero. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2644
<LI> libtiff/tif_dir.c, tif_dirread.c, tif_dirwrite.c: implement
various clampings of double to other data types to avoid
undefined behaviour if the output range isn't big enough to
hold the input value. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2643
http://bugzilla.maptools.org/show_bug.cgi?id=2642
http://bugzilla.maptools.org/show_bug.cgi?id=2646
http://bugzilla.maptools.org/show_bug.cgi?id=2647
<LI> libtiff/tif_jpeg.c: validate BitsPerSample in
JPEGSetupEncode() to avoid undefined behaviour caused by
invalid shift exponent. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2648
<LI> libtiff/tif_read.c: avoid potential undefined behaviour on
signed integer addition in TIFFReadRawStrip1() in isMapped()
case. Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2650
<LI> libtiff/tif_getimage.c: add explicit uint32 cast in
putagreytile to avoid UndefinedBehaviorSanitizer warning.
Patch by Nicolás Peña. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2658
<LI> libtiff/tif_read.c: TIFFReadBufferSetup(): use _TIFFcalloc()
to zero initialize tif_rawdata. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2651
<LI> libtiff/tiffio.h, tif_unix.c, tif_win32.c, tif_vms.c: add
_TIFFcalloc()
<LI> libtiff/tif_luv.c, tif_lzw.c, tif_packbits.c: return 0 in
Encode functions instead of -1 when TIFFFlushData1() fails.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2130
<LI> libtiff/tif_ojpeg.c: fix leak in
OJPEGReadHeaderInfoSecTablesQTable,
OJPEGReadHeaderInfoSecTablesDcTable and
OJPEGReadHeaderInfoSecTablesAcTable when read fails. Patch by
Nicolás Peña. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2659
<LI> libtiff/tif_jpeg.c: only run JPEGFixupTagsSubsampling() if
the YCbCrSubsampling tag is not explicitly present. This helps
a bit to reduce the I/O amount when the tag is present
(especially on cloud hosted files).
<LI> libtiff/tif_lzw.c: in LZWPostEncode(), increase, if
necessary, the code bit-width after flushing the remaining
code and before emitting the EOI code. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=1982
<LI> libtiff/tif_pixarlog.c: fix memory leak in error code path of
PixarLogSetupDecode(). Patch by Nicolás Peña. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2665
<LI> libtiff/tif_fax3.c, tif_predict.c, tif_getimage.c: fix GCC 7
-Wimplicit-fallthrough warnings.
<LI> libtiff/tif_dirread.c: fix memory leak in non
DEFER_STRILE_LOAD mode (ie default) when there is both a
StripOffsets and TileOffsets tag, or a StripByteCounts and
TileByteCounts Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2689
<LI> libtiff/tif_ojpeg.c: fix potential memory leak in
OJPEGReadHeaderInfoSecTablesQTable,
OJPEGReadHeaderInfoSecTablesDcTable and
OJPEGReadHeaderInfoSecTablesAcTable Patch by Nicolás Peña.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2670
<LI> libtiff/tif_fax3.c: avoid crash in Fax3Close() on empty file.
Patch by Alan Coopersmith + complement by myself. Fixes
http://bugzilla.maptools.org/show_bug.cgi?id=2673
<LI> libtiff/tif_read.c: TIFFFillStrip(): add limitation to the
number of bytes read in case td_stripbytecount[strip] is
bigger than reasonable, so as to avoid excessive memory
allocation.
<LI> libtiff/tif_zip.c, tif_pixarlog.c, tif_predict.c: fix memory
leak when the underlying codec (ZIP, PixarLog) succeeds its
setupdecode() method, but PredictorSetup fails. Credit to
OSS-Fuzz (locally run, on GDAL)
<LI> libtiff/tif_read.c: TIFFFillStrip() and TIFFFillTile(): avoid
excessive memory allocation in case of shorten files. Only
effective on 64 bit builds and non-mapped cases. Credit to
OSS-Fuzz (locally run, on GDAL)
<LI> libtiff/tif_read.c: TIFFFillStripPartial() / TIFFSeek(),
avoid potential integer overflows with read_ahead in
CHUNKY_STRIP_READ_SUPPORT mode. Should
especially occur on 32 bit platforms.
<LI> libtiff/tif_read.c: TIFFFillStripPartial(): avoid excessive
memory allocation in case of shorten files. Only effective on
64 bit builds. Credit to OSS-Fuzz (locally run, on GDAL)
<LI> libtiff/tif_read.c: update tif_rawcc in

<LI> libtiff/tif_lzw.c: update dec_bitsleft at beginning of
LZWDecode(), and update tif_rawcc at end of LZWDecode(). This
is needed to properly work with the latest chnges in
tif_read.c in CHUNKY_STRIP_READ_SUPPORT mode.
<LI> libtiff/tif_pixarlog.c: PixarLogDecode(): resync tif_rawcp
with next_in and tif_rawcc with avail_in at beginning and end
of function, similarly to what is done in LZWDecode(). Likely
needed so that it works properly with latest chnges in
tif_read.c in CHUNKY_STRIP_READ_SUPPORT mode. But untested...

<LI> test/Makefile.am: Add some tests for tiff2bw.
<LI> * .appveyor.yml, .travis.yml, build/travis-ci: apply patches
0001-ci-Travis-script-improvements.patch and
0002-ci-Invoke-helper-script-via-shell.patch by Roger Leigh
(sent to mailing list)
<LI> .travis.yml, build/travis-ci: new files from
0001-ci-Add-Travis-support-for-Linux-builds-with-Autoconf.patch by
Roger Leigh (sent to mailing list on 2017-06-08)
This patch adds support for the Travis-CI service.
<LI> .appveyor.yml: new file from
0002-ci-Add-AppVeyor-support.patch by Roger Leigh (sent to mailing
list on 2017-06-08)
This patch adds a .appveyor.yml file to the top-level. This allows
one to opt in to having a branch built on Windows with Cygwin,
MinGW and MSVC automatically when a branch is pushed to GitHub,
GitLab, BitBucket or any other supported git hosting service.
<LI> CMakeLists.txt, test/CMakeLists.txt, test/TiffTestCommon.cmake: apply
patch 0001-cmake-Improve-Cygwin-and-MingGW-test-support.patch from Roger
Leigh (sent to mailing list on 2017-06-08)
This patch makes the CMake build system support running the tests
with MinGW or Cygwin.
<LI> test/tiffcp-lzw-compat.sh, test/images/quad-lzw-compat.tiff: new files
to test old-style LZW decompression
<LI> test/common.sh, Makefile.am, CMakeList.txt: updated with above
<LI> test/Makefile.am: add missing reference to images/quad-lzw-compat.tiff
to fix "make distcheck". Patch by Roger Leigh

<LI> libtiff/tif_color.c: TIFFYCbCrToRGBInit(): stricter clamping to avoid
int32 overflow in TIFFYCbCrtoRGB().
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=1844
Credit to OSS Fuzz
<LI> libtiff/tif_getimage.c: initYCbCrConversion(): stricter validation for
refBlackWhite coefficients values. To avoid invalid float->int32 conversion
(when refBlackWhite[0] == 2147483648.f)
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=1907
Credit to OSS Fuzz
<LI> libtiff/tif_dirinfo.c, tif_dirread.c: add _TIFFCheckFieldIsValidForCodec(),
and use it in TIFFReadDirectory() so as to ignore fields whose tag is a
codec-specified tag but this codec is not enabled. This avoids TIFFGetField()
to behave differently depending on whether the codec is enabled or not, and
thus can avoid stack based buffer overflows in a number of TIFF utilities
such as tiffsplit, tiffcmp, thumbnail, etc.
Patch derived from 0063-Handle-properly-CODEC-specific-tags.patch

http://bugzilla.maptools.org/show_bug.cgi?id=2433
<LI> libtiff/tif_swab.c: if DISABLE_CHECK_TIFFSWABMACROS is defined, do not do
the #ifdef TIFFSwabXXX checks. Make it easier for GDAL to rename the symbols
of its internal libtiff copy.
<LI> libtiff/tif_dirread.c: fix regression of libtiff 4.0.8 in
ChopUpSingleUncompressedStrip() regarding update of newly single-strip
uncompressed files whose bytecount is 0. Before the change of 2016-12-03,
the condition bytecount==0 used to trigger an early exit/disabling of
strip chop. Re-introduce that in update mode. Otherwise this cause
later incorrect setting for the value of StripByCounts/StripOffsets.
( https://trac.osgeo.org/gdal/ticket/6924 )
<LI> libtiff/tif_dirread.c: TIFFFetchStripThing(): limit the number of items
read in StripOffsets/StripByteCounts tags to the number of strips to avoid
excessive memory allocation.
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2215
Credit to OSS Fuzz
<LI> libtiff/tif_getimage.c: avoid many (harmless) unsigned int overflows.
<LI> libtiff/tif_fax3.c: avoid unsigned int overflow in Fax3Encode2DRow(). Could
potentially be a bug with huge rows.
<LI> libtiff/tif_jpeg.c: avoid (harmless) unsigned int overflow on tiled images.
<LI> libtiff/tif_dirread.c: avoid unsigned int overflow in EstimateStripByteCounts()
and BYTECOUNTLOOKSBAD when file is too short.
<LI> libtiff/tif_predict.c: decorate legitimate functions where unsigned int
overflow occur with TIFF_NOSANITIZE_UNSIGNED_INT_OVERFLOW
* libtiff/tif_dirread.c: avoid unsigned int overflow in EstimateStripByteCounts()
<LI> libtiff/tiffiop.h: add TIFF_NOSANITIZE_UNSIGNED_INT_OVERFLOW macro to
disable CLang warnings raised by -fsanitize=undefined,unsigned-integer-overflow
<LI> libtiff/tif_jpeg.c: add anti-denial of service measure to avoid excessive
CPU consumption on progressive JPEGs with a huge number of scans.
See http://www.libjpeg-turbo.org/pmwiki/uploads/About/TwoIssueswiththeJPEGStandard.pdf
Note: only affects libtiff since 2014-12-29 where support of non-baseline JPEG
was added.
<LI> libtiff/tif_jpeg.c: error out at decoding time if anticipated libjpeg
memory allocation is above 100 MB. libjpeg in case of multiple scans,
which is allowed even in baseline JPEG, if components are spread over several
scans and not interleavedin a single one, needs to allocate memory (or
backing store) for the whole strip/tile.
See http://www.libjpeg-turbo.org/pmwiki/uploads/About/TwoIssueswiththeJPEGStandard.pdf
This limitation may be overriden by setting the
LIBTIFF_ALLOW_LARGE_LIBJPEG_MEM_ALLOC environment variable, or recompiling
libtiff with a custom value of TIFF_LIBJPEG_LARGEST_MEM_ALLOC macro.
<LI> libtiff/tif_jbig.c: fix memory leak in error code path of JBIGDecode()
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2706
Reported by team OWL337
<LI> libtiff/tif_dirread.c: in TIFFReadDirEntryFloat(), check that a
double value can fit in a float before casting. Patch by Nicolas RUFF
<LI> libtiff/tiffiop.h, libtiff/tif_jpeg.c, libtiff/tif_jpeg_12.c,
libtiff/tif_read.c: make TIFFReadScanline() works in
CHUNKY_STRIP_READ_SUPPORT mode with JPEG stream with multiple scans.
Also make configurable through a LIBTIFF_JPEG_MAX_ALLOWED_SCAN_NUMBER
environment variable the maximum number of scans allowed. Defaults to
100.
<LI> libtiff/tif_read.c: TIFFFillTile(): add limitation to the number
of bytes read in case td_stripbytecount[strip] is bigger than
reasonable, so as to avoid excessive memory allocation (similarly to
what was done for TIFFFileStrip() on 2017-05-10)
<LI> libtiff/tif_getimage.c: use _TIFFReadEncodedStripAndAllocBuffer().
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2708 and
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2433 .
Credit to OSS Fuzz
<LI> libtiff/tif_read.c, tiffiop.h: add a _TIFFReadEncodedStripAndAllocBuffer()
function, variant of TIFFReadEncodedStrip() that allocates the
decoded buffer only after a first successful TIFFFillStrip(). This avoids
excessive memory allocation on corrupted files.
<LI> libtiff/tif_dirwrite.c: in TIFFWriteDirectoryTagCheckedXXXX()
functions associated with LONG8/SLONG8 data type, replace assertion that
the file is BigTIFF, by a non-fatal error.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2712
Reported by team OWL337
<LI> libtiff/tif_read.c: TIFFStartTile(): set tif_rawcc to
tif_rawdataloaded when it is set. Similarly to TIFFStartStrip().
This issue was revealed by the change of 2017-06-30 in TIFFFileTile(),
limiting the number of bytes read. But it could probably have been hit
too in CHUNKY_STRIP_READ_SUPPORT mode previously ?
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2454

<LI> libtiff/tif_error.c, tif_warning.c: correctly use va_list when both
an old-style and new-style warning/error handlers are installed.
Patch by Paavo Helde (sent on the mailing list)
<LI> libtiff/tif_getimage.c: use _TIFFReadTileAndAllocBuffer().
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2470
Credit to OSS Fuzz.
<LI> libtiff/tif_read.c, tiffiop.h: add a _TIFFReadEncodedTileAndAllocBuffer()
and _TIFFReadTileAndAllocBuffer() variants of TIFFReadEncodedTile() and
TIFFReadTile() that allocates the decoded buffer only after a first
successful TIFFFillTile(). This avoids excessive memory allocation
on corrupted files.
<LI> libtiff/tif_pixarlog.c: avoid excessive memory allocation on decoding
when RowsPerStrip tag is not defined (and thus td_rowsperstrip == UINT_MAX)
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2554
Credit to OSS Fuzz
<LI> libtiff/tif_lzw.c: fix 4.0.8 regression in the decoding of old-style LZW
compressed files.
<LI> libtiff/tif_lzw.c: fix potential out-of-buffer read on 1-byte LZW
strips. Crashing issue only on memory mapped files, where the strip
offset is the last byte of the file, and the file size is a multiple
of one page size on the CPU architecture (typically 4096). Credit
to myself :-)
<LI> libtiff/tif_dir.c: avoid potential null pointer dereference in
_TIFFVGetField() on corrupted TIFFTAG_NUMBEROFINKS tag instance.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2713
<LI> tools/tiff2pdf.c: prevent heap buffer overflow write in "Raw"
mode on PlanarConfig=Contig input images.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2715
Reported by team OWL337
<LI> libtiff/tif_read.c: TIFFFillStrip() / TIFFFillTile().
Complementary fix for http://bugzilla.maptools.org/show_bug.cgi?id=2708
in the isMapped() case, so as to avoid excessive memory allocation
when we need a temporary buffer but the file is truncated.
<LI> libtiff/tif_read.c: TIFFFillStrip() / TIFFFillTile().
Complementary fix for http://bugzilla.maptools.org/show_bug.cgi?id=2708
in the isMapped() case, so as to avoid excessive memory allocation
when we need a temporary buffer but the file is truncated.
<LI> libtiff/tif_read.c: in TIFFFetchStripThing(), only grow the
arrays that hold StripOffsets/StripByteCounts, when they are smaller
than the expected number of striles, up to 1 million striles, and
error out beyond. Can be tweaked by setting the environment variable
LIBTIFF_STRILE_ARRAY_MAX_RESIZE_COUNT.
This partially goes against a change added on 2002-12-17 to accept
those arrays of wrong sizes, but is needed to avoid denial of services.

<LI> libtiff/tif_getimage.c: gtTileContig() and gtTileSeparate():
properly break from loops on error when stoponerr is set, instead
of going on iterating on row based loop.
<LI> libtiff/tif_getimage.c: fix fromskew computation when to-be-skipped
pixel number is not a multiple of the horizontal subsampling, and
also in some other cases. Impact putcontig8bitYCbCr44tile,
putcontig8bitYCbCr42tile, putcontig8bitYCbCr41tile,
putcontig8bitYCbCr21tile and putcontig8bitYCbCr12tile

(in TIFFWriteDirectoryTagSubifd()).
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2728
Reported by team OWL337
<LI> libtiff/tif_jpeg.c: accept reading the last strip of a JPEG compressed
file if the codestream height is larger than the truncated height of the
strip. Emit a warning in this situation since this is non compliant.
<LI> libtiff/tiffiop.h, tif_aux.c: redirect SeekOK() macro to a _TIFFSeekoK()
function that checks if the offset is not bigger than INT64_MAX, so as
to avoid a -1 error return code of TIFFSeekFile() to match a required
seek to UINT64_MAX/-1.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2726
Adapted from proposal by Nicolas Ruff.
<LI> libtiff/tif_dirread.c: add NULL check to avoid likely false positive
null-pointer dereference warning by CLang Static Analyzer.

DRAFT TIFF Technical Note #2 17-Mar-95
============================
This Technical Note describes serious problems that have been found in
TIFF 6.0's design for embedding JPEG-compressed data in TIFF (Section 22
of the TIFF 6.0 spec of 3 June 1992). A replacement TIFF/JPEG
specification is given. Some corrections to Section 21 are also given.
To permit TIFF implementations to continue to read existing files, the 6.0
JPEG fields and tag values will remain reserved indefinitely. However,
TIFF writers are strongly discouraged from using the 6.0 JPEG design. It
is expected that the next full release of the TIFF specification will not
describe the old design at all, except to note that certain tag numbers
are reserved. The existing Section 22 will be replaced by the
specification text given in the second part of this Tech Note.
Problems in TIFF 6.0 JPEG
=========================
Abandoning a published spec is not a step to be taken lightly. This
section summarizes the reasons that have forced this decision.
TIFF 6.0's JPEG design suffers from design errors and limitations,
ambiguities, and unnecessary complexity.
Design errors and limitations
-----------------------------
The fundamental design error in the existing Section 22 is that JPEG's
various tables and parameters are broken out as separate fields which the
TIFF control logic must manage. This is bad software engineering: that
information should be treated as private to the JPEG codec
(compressor/decompressor). Worse, the fields themselves are specified
without sufficient thought for future extension and without regard to
well-established TIFF conventions. Here are some of the significant
problems:
* The JPEGxxTable fields do not store the table data directly in the
IFD/field structure; rather, the fields hold pointers to information
elsewhere in the file. This requires special-purpose code to be added to
*every* TIFF-manipulating application, whether it needs to decode JPEG
image data or not. Even a trivial TIFF editor, for example a program to
add an ImageDescription field to a TIFF file, must be explicitly aware of
the internal structure of the JPEG-related tables, or else it will probably
break the file. Every other auxiliary field in the TIFF spec contains
data, not pointers, and can be copied or relocated by standard code that
doesn't know anything about the particular field. This is a crucial
property of the TIFF format that must not be given up.
* To manipulate these fields, the TIFF control logic is required to know a
great deal about JPEG details, for example such arcana as how to compute
the length of a Huffman code table --- the length is not supplied in the
field structure and can only be found by inspecting the table contents.
This is again a violation of good software practice. Moreover, it will
prevent easy adoption of future JPEG extensions that might change these
low-level details.
* The design neglects the fact that baseline JPEG codecs support only two
sets of Huffman tables: it specifies a separate table for each color
component. This implies that encoders must waste space (by storing
duplicate Huffman tables) or else violate the well-founded TIFF convention
that prohibits duplicate pointers. Furthermore, baseline decoders must
test to find out which tables are identical, a waste of time and code
space.
* The JPEGInterchangeFormat field also violates TIFF's proscription against
duplicate pointers: the normal strip/tile pointers are expected to point
into the larger data area pointed to by JPEGInterchangeFormat. All TIFF
editing applications must be specifically aware of this relationship, since
they must maintain it or else delete the JPEGInterchangeFormat field. The
JPEGxxTables fields are also likely to point into the JPEGInterchangeFormat
area, creating additional pointer relationships that must be maintained.
* The JPEGQTables field is fixed at a byte per table entry; there is no
way to support 16-bit quantization values. This is a serious impediment
to extending TIFF to use 12-bit JPEG.
* The 6.0 design cannot support using different quantization tables in
different strips/tiles of an image (so as to encode some areas at higher
quality than others). Furthermore, since quantization tables are tied
one-for-one to color components, the design cannot support table switching
options that are likely to be added in future JPEG revisions.
Ambiguities
-----------
Several incompatible interpretations are possible for 6.0's treatment of
JPEG restart markers:
* It is unclear whether restart markers must be omitted at TIFF segment
(strip/tile) boundaries, or whether they are optional.
* It is unclear whether the segment size is required to be chosen as
a multiple of the specified restart interval (if any); perhaps the
JPEG codec is supposed to be reset at each segment boundary as if
there were a restart marker there, even if the boundary does not fall
at a multiple of the nominal restart interval.
* The spec fails to address the question of restart marker numbering:
do the numbers begin again within each segment, or not?
That last point is particularly nasty. If we make numbering begin again
within each segment, we give up the ability to impose a TIFF strip/tile
structure on an existing JPEG datastream with restarts (which was clearly a
goal of Section 22's authors). But the other choice interferes with random
access to the image segments: a reader must compute the first restart
number to be expected within a segment, and must have a way to reset its
JPEG decoder to expect a nonzero restart number first. This may not even
be possible with some JPEG chips.
The tile height restriction found on page 104 contradicts Section 15's
general description of tiles. For an image that is not vertically
downsampled, page 104 specifies a tile height of one MCU or 8 pixels; but
Section 15 requires tiles to be a multiple of 16 pixels high.
This Tech Note does not attempt to resolve these ambiguities, so
implementations that follow the 6.0 design should be aware that
inter-application compatibility problems are likely to arise.
Unnecessary complexity
----------------------
The 6.0 design creates problems for implementations that need to keep the
JPEG codec separate from the TIFF control logic --- for example, consider
using a JPEG chip that was not designed specifically for TIFF. JPEG codecs
generally want to produce or consume a standard ISO JPEG datastream, not
just raw compressed data. (If they were to handle raw data, a separate
out-of-band mechanism would be needed to load tables into the codec.)
With such a codec, the TIFF control logic must parse JPEG markers emitted
by the codec to create the TIFF table fields (when writing) or synthesize
JPEG markers from the TIFF fields to feed the codec (when reading). This
means that the control logic must know a great deal more about JPEG details
than we would like. The parsing and reconstruction of the markers also
represents a fair amount of unnecessary work.
Quite a few implementors have proposed writing "TIFF/JPEG" files in which
a standard JPEG datastream is simply dumped into the file and pointed to
by JPEGInterchangeFormat. To avoid parsing the JPEG datastream, they
suggest not writing the JPEG auxiliary fields (JPEGxxTables etc) nor even
the basic TIFF strip/tile data pointers. This approach is incompatible
with implementations that handle the full TIFF 6.0 JPEG design, since they
will expect to find strip/tile pointers and auxiliary fields. Indeed this
is arguably not TIFF at all, since *all* TIFF-reading applications expect
to find strip or tile pointers. A subset implementation that is not
upward-compatible with the full spec is clearly unacceptable. However,
the frequency with which this idea has come up makes it clear that
implementors find the existing Section 22 too complex.
Overview of the solution
========================
To solve these problems, we adopt a new design for embedding
JPEG-compressed data in TIFF files. The new design uses only complete,
uninterpreted ISO JPEG datastreams, so it should be much more forgiving of
extensions to the ISO standard. It should also be far easier to implement
using unmodified JPEG codecs.
To reduce overhead in multi-segment TIFF files, we allow JPEG overhead
tables to be stored just once in a JPEGTables auxiliary field. This
feature does not violate the integrity of the JPEG datastreams, because it
uses the notions of "tables-only datastreams" and "abbreviated image
datastreams" as defined by the ISO standard.
To prevent confusion with the old design, the new design is given a new
Compression tag value, Compression=7. Readers that need to handle
existing 6.0 JPEG files may read both old and new files, using whatever
interpretation of the 6.0 spec they did before. Compression tag value 6
and the field tag numbers defined by 6.0 section 22 will remain reserved
indefinitely, even though detailed descriptions of them will be dropped
from future editions of the TIFF specification.
Replacement TIFF/JPEG specification
===================================
[This section of the Tech Note is expected to replace Section 22 in the
next release of the TIFF specification.]
This section describes TIFF compression scheme 7, a high-performance
compression method for continuous-tone images.
Introduction
------------
This TIFF compression method uses the international standard for image
compression ISO/IEC 10918-1, usually known as "JPEG" (after the original
name of the standards committee, Joint Photographic Experts Group). JPEG
is a joint ISO/CCITT standard for compression of continuous-tone images.
The JPEG committee decided that because of the broad scope of the standard,
no one algorithmic procedure was able to satisfy the requirements of all
applications. Instead, the JPEG standard became a "toolkit" of multiple
algorithms and optional capabilities. Individual applications may select
a subset of the JPEG standard that meets their requirements.
The most important distinction among the JPEG processes is between lossy
and lossless compression. Lossy compression methods provide high
compression but allow only approximate reconstruction of the original
image. JPEG's lossy processes allow the encoder to trade off compressed
file size against reconstruction fidelity over a wide range. Typically,
10:1 or more compression of full-color data can be obtained while keeping
the reconstructed image visually indistinguishable from the original. Much
higher compression ratios are possible if a low-quality reconstructed image
is acceptable. Lossless compression provides exact reconstruction of the
source data, but the achievable compression ratio is much lower than for
the lossy processes; JPEG's rather simple lossless process typically
achieves around 2:1 compression of full-color data.
The most widely implemented JPEG subset is the "baseline" JPEG process.
This provides lossy compression of 8-bit-per-channel data. Optional
extensions include 12-bit-per-channel data, arithmetic entropy coding for
better compression, and progressive/hierarchical representations. The
lossless process is an independent algorithm that has little in
common with the lossy processes.
It should be noted that the optional arithmetic-coding extension is subject
to several US and Japanese patents. To avoid patent problems, use of
arithmetic coding processes in TIFF files intended for inter-application
interchange is discouraged.
All of the JPEG processes are useful only for "continuous tone" data,
in which the difference between adjacent pixel values is usually small.
Low-bit-depth source data is not appropriate for JPEG compression, nor
are palette-color images good candidates. The JPEG processes work well
on grayscale and full-color data.
Describing the JPEG compression algorithms in sufficient detail to permit
implementation would require more space than we have here. Instead, we
refer the reader to the References section.
What data is being compressed?
------------------------------
In lossy JPEG compression, it is customary to convert color source data
to YCbCr and then downsample it before JPEG compression. This gives
2:1 data compression with hardly any visible image degradation, and it
permits additional space savings within the JPEG compression step proper.
However, these steps are not considered part of the ISO JPEG standard.
The ISO standard is "color blind": it accepts data in any color space.
For TIFF purposes, the JPEG compression tag is considered to represent the
ISO JPEG compression standard only. The ISO standard is applied to the
same data that would be stored in the TIFF file if no compression were
used. Therefore, if color conversion or downsampling are used, they must
be reflected in the regular TIFF fields; these steps are not considered to
be implicit in the JPEG compression tag value. PhotometricInterpretation
and related fields shall describe the color space actually stored in the
file. With the TIFF 6.0 field definitions, downsampling is permissible
only for YCbCr data, and it must correspond to the YCbCrSubSampling field.
(Note that the default value for this field is not 1,1; so the default for
YCbCr is to apply downsampling!) It is likely that future versions of TIFF
will provide additional PhotometricInterpretation values and a more general
way of defining subsampling, so as to allow more flexibility in
JPEG-compressed files. But that issue is not addressed in this Tech Note.
Implementors should note that many popular JPEG codecs
(compressor/decompressors) provide automatic color conversion and
downsampling, so that the application may supply full-size RGB data which
is nonetheless converted to downsampled YCbCr. This is an implementation
convenience which does not excuse the TIFF control layer from its
responsibility to know what is really going on. The
PhotometricInterpretation and subsampling fields written to the file must
describe what is actually in the file.
A JPEG-compressed TIFF file will typically have PhotometricInterpretation =
YCbCr and YCbCrSubSampling = [2,1] or [2,2], unless the source data was
grayscale or CMYK.
Basic representation of JPEG-compressed images
----------------------------------------------
JPEG compression works in either strip-based or tile-based TIFF files.
Rather than repeating "strip or tile" constantly, we will use the term
"segment" to mean either a strip or a tile.
When the Compression field has the value 7, each image segment contains
a complete JPEG datastream which is valid according to the ISO JPEG
standard (ISO/IEC 10918-1). Any sequential JPEG process can be used,
including lossless JPEG, but progressive and hierarchical processes are not
supported. Since JPEG is useful only for continuous-tone images, the
PhotometricInterpretation of the image shall not be 3 (palette color) nor
4 (transparency mask). The bit depth of the data is also restricted as
specified below.
Each image segment in a JPEG-compressed TIFF file shall contain a valid
JPEG datastream according to the ISO JPEG standard's rules for
interchange-format or abbreviated-image-format data. The datastream shall
contain a single JPEG frame storing that segment of the image. The
required JPEG markers within a segment are:
SOI (must appear at very beginning of segment)
SOFn
SOS (one for each scan, if there is more than one scan)
EOI (must appear at very end of segment)
The actual compressed data follows SOS; it may contain RSTn markers if DRI
is used.
Additional JPEG "tables and miscellaneous" markers may appear between SOI
and SOFn, between SOFn and SOS, and before each subsequent SOS if there is
more than one scan. These markers include:
DQT
DHT
DAC (not to appear unless arithmetic coding is used)
DRI
APPn (shall be ignored by TIFF readers)
COM (shall be ignored by TIFF readers)
DNL markers shall not be used in TIFF files. Readers should abort if any
other marker type is found, especially the JPEG reserved markers;
occurrence of such a marker is likely to indicate a JPEG extension.
The tables/miscellaneous markers may appear in any order. Readers are
cautioned that although the SOFn marker refers to DQT tables, JPEG does not
require those tables to precede the SOFn, only the SOS. Missing-table
checks should be made when SOS is reached.
If no JPEGTables field is used, then each image segment shall be a complete
JPEG interchange datastream. Each segment must define all the tables it
references. To allow readers to decode segments in any order, no segment
may rely on tables being carried over from a previous segment.
When a JPEGTables field is used, image segments may omit tables that have
been specified in the JPEGTables field. Further details appear below.
The SOFn marker shall be of type SOF0 for strict baseline JPEG data, of
type SOF1 for non-baseline lossy JPEG data, or of type SOF3 for lossless
JPEG data. (SOF9 or SOF11 would be used for arithmetic coding.) All
segments of a JPEG-compressed TIFF image shall use the same JPEG
compression process, in particular the same SOFn type.
The data precision field of the SOFn marker shall agree with the TIFF
BitsPerSample field. (Note that when PlanarConfiguration=1, this implies
that all components must have the same BitsPerSample value; when
PlanarConfiguration=2, different components could have different bit
depths.) For SOF0 only precision 8 is permitted; for SOF1, precision 8 or
12 is permitted; for SOF3, precisions 2 to 16 are permitted.
The image dimensions given in the SOFn marker shall agree with the logical
dimensions of that particular strip or tile. For strip images, the SOFn
image width shall equal ImageWidth and the height shall equal RowsPerStrip,
except in the last strip; its SOFn height shall equal the number of rows
remaining in the ImageLength. (In other words, no padding data is counted
in the SOFn dimensions.) For tile images, each SOFn shall have width
TileWidth and height TileHeight; adding and removing any padding needed in
the edge tiles is the concern of some higher level of the TIFF software.
(The dimensional rules are slightly different when PlanarConfiguration=2,
as described below.)
The ISO JPEG standard only permits images up to 65535 pixels in width or
height, due to 2-byte fields in the SOFn markers. In TIFF, this limits
the size of an individual JPEG-compressed strip or tile, but the total
image size can be greater.
The number of components in the JPEG datastream shall equal SamplesPerPixel
for PlanarConfiguration=1, and shall be 1 for PlanarConfiguration=2. The
components shall be stored in the same order as they are described at the
TIFF field level. (This applies both to their order in the SOFn marker,
and to the order in which they are scanned if multiple JPEG scans are
used.) The component ID bytes are arbitrary so long as each component
within an image segment is given a distinct ID. To avoid any possible
confusion, we require that all segments of a TIFF image use the same ID
code for a given component.
In PlanarConfiguration 1, the sampling factors given in SOFn markers shall
agree with the sampling factors defined by the related TIFF fields (or with
the default values that are specified in the absence of those fields).
When DCT-based JPEG is used in a strip TIFF file, RowsPerStrip is required
to be a multiple of 8 times the largest vertical sampling factor, i.e., a
multiple of the height of an interleaved MCU. (For simplicity of
specification, we require this even if the data is not actually
interleaved.) For example, if YCbCrSubSampling = [2,2] then RowsPerStrip
must be a multiple of 16. An exception to this rule is made for
single-strip images (RowsPerStrip >= ImageLength): the exact value of
RowsPerStrip is unimportant in that case. This rule ensures that no data
padding is needed at the bottom of a strip, except perhaps the last strip.
Any padding required at the right edge of the image, or at the bottom of
the last strip, is expected to occur internally to the JPEG codec.
When DCT-based JPEG is used in a tiled TIFF file, TileLength is required
to be a multiple of 8 times the largest vertical sampling factor, i.e.,
a multiple of the height of an interleaved MCU; and TileWidth is required
to be a multiple of 8 times the largest horizontal sampling factor, i.e.,
a multiple of the width of an interleaved MCU. (For simplicity of
specification, we require this even if the data is not actually
interleaved.) All edge padding required will therefore occur in the course
of normal TIFF tile padding; it is not special to JPEG.
Lossless JPEG does not impose these constraints on strip and tile sizes,
since it is not DCT-based.
Note that within JPEG datastreams, multibyte values appear in the MSB-first
order specified by the JPEG standard, regardless of the byte ordering of
the surrounding TIFF file.
JPEGTables field
----------------
The only auxiliary TIFF field added for Compression=7 is the optional
JPEGTables field. The purpose of JPEGTables is to predefine JPEG
quantization and/or Huffman tables for subsequent use by JPEG image
segments. When this is done, these rather bulky tables need not be
duplicated in each segment, thus saving space and processing time.
JPEGTables may be used even in a single-segment file, although there is no
space savings in that case.
JPEGTables:
Tag = 347 (15B.H)
Type = UNDEFINED
N = number of bytes in tables datastream, typically a few hundred
JPEGTables provides default JPEG quantization and/or Huffman tables which
are used whenever a segment datastream does not contain its own tables, as
specified below.
Notice that the JPEGTables field is required to have type code UNDEFINED,
not type code BYTE. This is to cue readers that expanding individual bytes
to short or long integers is not appropriate. A TIFF reader will generally
need to store the field value as an uninterpreted byte sequence until it is
fed to the JPEG decoder.
Multibyte quantities within the tables follow the ISO JPEG convention of
MSB-first storage, regardless of the byte ordering of the surrounding TIFF
file.
When the JPEGTables field is present, it shall contain a valid JPEG
"abbreviated table specification" datastream. This datastream shall begin
with SOI and end with EOI. It may contain zero or more JPEG "tables and
miscellaneous" markers, namely:
DQT
DHT
DAC (not to appear unless arithmetic coding is used)
DRI
APPn (shall be ignored by TIFF readers)
COM (shall be ignored by TIFF readers)
Since JPEG defines the SOI marker to reset the DAC and DRI state, these two
markers' values cannot be carried over into any image datastream, and thus
they are effectively no-ops in the JPEGTables field. To avoid confusion,
it is recommended that writers not place DAC or DRI markers in JPEGTables.
However readers must properly skip over them if they appear.
When JPEGTables is present, readers shall load the table specifications
contained in JPEGTables before processing image segment datastreams.
Image segments may simply refer to these preloaded tables without defining
them. An image segment can still define and use its own tables, subject to
the restrictions below.
An image segment may not redefine any table defined in JPEGTables. (This
restriction is imposed to allow readers to process image segments in random
order without having to reload JPEGTables between segments.) Therefore, use
of JPEGTables divides the available table slots into two groups: "global"
slots are defined in JPEGTables and may be used but not redefined by
segments; "local" slots are available for local definition and use in each
segment. To permit random access, a segment may not reference any local
tables that it does not itself define.
Special considerations for PlanarConfiguration 2
------------------------------------------------
In PlanarConfiguration 2, each image segment contains data for only one
color component. To avoid confusing the JPEG codec, we wish the segments
to look like valid single-channel (i.e., grayscale) JPEG datastreams. This
means that different rules must be used for the SOFn parameters.
In PlanarConfiguration 2, the dimensions given in the SOFn of a subsampled
component shall be scaled down by the sampling factors compared to the SOFn
dimensions that would be used in PlanarConfiguration 1. This is necessary
to match the actual number of samples stored in that segment, so that the
JPEG codec doesn't complain about too much or too little data. In strip
TIFF files the computed dimensions may need to be rounded up to the next
integer; in tiled files, the restrictions on tile size make this case
impossible.
Furthermore, all SOFn sampling factors shall be given as 1. (This is
merely to avoid confusion, since the sampling factors in a single-channel
JPEG datastream have no real effect.)
Any downsampling will need to happen externally to the JPEG codec, since
JPEG sampling factors are defined with reference to the full-precision
component. In PlanarConfiguration 2, the JPEG codec will be working on
only one component at a time and thus will have no reference component to
downsample against.
Minimum requirements for TIFF/JPEG
----------------------------------
ISO JPEG is a large and complex standard; most implementations support only
a subset of it. Here we define a "core" subset of TIFF/JPEG which readers
must support to claim TIFF/JPEG compatibility. For maximum
cross-application compatibility, we recommend that writers confine
themselves to this subset unless there is very good reason to do otherwise.
Use the ISO baseline JPEG process: 8-bit data precision, Huffman coding,
with no more than 2 DC and 2 AC Huffman tables. Note that this implies
BitsPerSample = 8 for each component. We recommend deviating from baseline
JPEG only if 12-bit data precision or lossless coding is required.
Use no subsampling (all JPEG sampling factors = 1) for color spaces other
than YCbCr. (This is, in fact, required with the TIFF 6.0 field
definitions, but may not be so in future revisions.) For YCbCr, use one of
the following choices:
YCbCrSubSampling field JPEG sampling factors
1,1 1h1v, 1h1v, 1h1v
2,1 2h1v, 1h1v, 1h1v
2,2 (default value) 2h2v, 1h1v, 1h1v
We recommend that RGB source data be converted to YCbCr for best compression
results. Other source data colorspaces should probably be left alone.
Minimal readers need not support JPEG images with colorspaces other than
YCbCr and grayscale (PhotometricInterpretation = 6 or 1).
A minimal reader also need not support JPEG YCbCr images with nondefault
values of YCbCrCoefficients or YCbCrPositioning, nor with values of
ReferenceBlackWhite other than [0,255,128,255,128,255]. (These values
correspond to the RGB<=>YCbCr conversion specified by JFIF, which is widely
implemented in JPEG codecs.)
Writers are reminded that a ReferenceBlackWhite field *must* be included
when PhotometricInterpretation is YCbCr, because the default
ReferenceBlackWhite values are inappropriate for YCbCr.
If any subsampling is used, PlanarConfiguration=1 is preferred to avoid the
possibly-confusing requirements of PlanarConfiguration=2. In any case,
readers are not required to support PlanarConfiguration=2.
If possible, use a single interleaved scan in each image segment. This is
not legal JPEG if there are more than 4 SamplesPerPixel or if the sampling
factors are such that more than 10 blocks would be needed per MCU; in that
case, use a separate scan for each component. (The recommended color
spaces and sampling factors will not run into that restriction, so a
minimal reader need not support more than one scan per segment.)
To claim TIFF/JPEG compatibility, readers shall support multiple-strip TIFF
files and the optional JPEGTables field; it is not acceptable to read only
single-datastream files. Support for tiled TIFF files is strongly
recommended but not required.
Other recommendations for implementors
--------------------------------------
The TIFF tag Compression=7 guarantees only that the compressed data is
represented as ISO JPEG datastreams. Since JPEG is a large and evolving
standard, readers should apply careful error checking to the JPEG markers
to ensure that the compression process is within their capabilities. In
particular, to avoid being confused by future extensions to the JPEG
standard, it is important to abort if unknown marker codes are seen.
The point of requiring that all image segments use the same JPEG process is
to ensure that a reader need check only one segment to determine whether it
can handle the image. For example, consider a TIFF reader that has access
to fast but restricted JPEG hardware, as well as a slower, more general
software implementation. It is desirable to check only one image segment
to find out whether the fast hardware can be used. Thus, writers should
try to ensure that all segments of an image look as much "alike" as
possible: there should be no variation in scan layout, use of options such
as DRI, etc. Ideally, segments will be processed identically except
perhaps for using different local quantization or entropy-coding tables.
Writers should avoid including "noise" JPEG markers (COM and APPn markers).
Standard TIFF fields provide a better way to transport any non-image data.
Some JPEG codecs may change behavior if they see an APPn marker they
think they understand; since the TIFF spec requires these markers to be
ignored, this behavior is undesirable.
It is possible to convert an interchange-JPEG file (e.g., a JFIF file) to
TIFF simply by dropping the interchange datastream into a single strip.
(However, designers are reminded that the TIFF spec discourages huge
strips; splitting the image is somewhat more work but may give better
results.) Conversion from TIFF to interchange JPEG is more complex. A
strip-based TIFF/JPEG file can be converted fairly easily if all strips use
identical JPEG tables and no RSTn markers: just delete the overhead markers
and insert RSTn markers between strips. Converting tiled images is harder,
since the data will usually not be in the right order (unless the tiles are
only one MCU high). This can still be done losslessly, but it will require
undoing and redoing the entropy coding so that the DC coefficient
differences can be updated.
There is no default value for JPEGTables: standard TIFF files must define all
tables that they reference. For some closed systems in which many files will
have identical tables, it might make sense to define a default JPEGTables
value to avoid actually storing the tables. Or even better, invent a
private field selecting one of N default JPEGTables settings, so as to allow
for future expansion. Either of these must be regarded as a private
extension that will render the files unreadable by other applications.

Changes to Section 21: YCbCr Images
===================================
[This section of the Tech Note clarifies section 21 to make clear the
interpretation of image dimensions in a subsampled image. Furthermore,
the section is changed to allow the original image dimensions not to be
multiples of the sampling factors. This change is necessary to support use
of JPEG compression on odd-size images.]
Add the following paragraphs to the Section 21 introduction (p. 89),
just after the paragraph beginning "When a Class Y image is subsampled":
In a subsampled image, it is understood that all TIFF image
dimensions are measured in terms of the highest-resolution
(luminance) component. In particular, ImageWidth, ImageLength,
RowsPerStrip, TileWidth, TileLength, XResolution, and YResolution
are measured in luminance samples.
RowsPerStrip, TileWidth, and TileLength are constrained so that
there are an integral number of samples of each component in a
complete strip or tile. However, ImageWidth/ImageLength are not
constrained. If an odd-size image is to be converted to subsampled
format, the writer should pad the source data to a multiple of the
sampling factors by replication of the last column and/or row, then
downsample. The number of luminance samples actually stored in the
file will be a multiple of the sampling factors. Conversely,
readers must ignore any extra data (outside the specified image
dimensions) after upsampling.
When PlanarConfiguration=2, each strip or tile covers the same
image area despite subsampling; that is, the total number of strips
or tiles in the image is the same for each component. Therefore
strips or tiles of the subsampled components contain fewer samples
than strips or tiles of the luminance component.
If there are extra samples per pixel (see field ExtraSamples),
these data channels have the same number of samples as the
luminance component.
Rewrite the YCbCrSubSampling field description (pp 91-92) as follows
(largely to eliminate possibly-misleading references to
ImageWidth/ImageLength of the subsampled components):
(first paragraph unchanged)
The two elements of this field are defined as follows:
Short 0: ChromaSubsampleHoriz:
1 = there are equal numbers of luma and chroma samples horizontally.
2 = there are twice as many luma samples as chroma samples
horizontally.
4 = there are four times as many luma samples as chroma samples
horizontally.
Short 1: ChromaSubsampleVert:
1 = there are equal numbers of luma and chroma samples vertically.
2 = there are twice as many luma samples as chroma samples
vertically.
4 = there are four times as many luma samples as chroma samples
vertically.
ChromaSubsampleVert shall always be less than or equal to
ChromaSubsampleHoriz. Note that Cb and Cr have the same sampling
ratios.
In a strip TIFF file, RowsPerStrip is required to be an integer
multiple of ChromaSubSampleVert (unless RowsPerStrip >=
ImageLength, in which case its exact value is unimportant).
If ImageWidth and ImageLength are not multiples of
ChromaSubsampleHoriz and ChromaSubsampleVert respectively, then the
source data shall be padded to the next integer multiple of these
values before downsampling.
In a tiled TIFF file, TileWidth must be an integer multiple of
ChromaSubsampleHoriz and TileLength must be an integer multiple of
ChromaSubsampleVert. Padding will occur to tile boundaries.
The default values of this field are [ 2,2 ]. Thus, YCbCr data is
downsampled by default!

Defining New TIFF Tags
</H1>
Libtiff has built-in knowledge of all the standard TIFF tags, as
well as extentions. The following describes how to add knowledge of
new tags as builtins to libtiff, or how to application specific tags can
be used by applications without modifying libtiff.
<p>
<h2>TIFFFieldInfo</h2>
How libtiff manages specific tags is primarily controlled by the
definition for that tag value stored internally as a TIFFFieldInfo structure.
This structure looks like this:
<p>
<pre>
typedef struct {
ttag_t field_tag; /* field's tag */
short field_readcount; /* read count/TIFF_VARIABLE/TIFF_SPP */
short field_writecount; /* write count/TIFF_VARIABLE */
TIFFDataType field_type; /* type of associated data */
unsigned short field_bit; /* bit in fieldsset bit vector */
unsigned char field_oktochange;/* if true, can change while writing */
unsigned char field_passcount;/* if true, pass dir count on set */
char *field_name; /* ASCII name */
} TIFFFieldInfo;
</pre>
<ul>
<li> <b>field_tag</b>: the tag number. For instance 277 for the
SamplesPerPixel tag. Builtin tags will generally have a #define in
tiff.h for each known tag. <p>
<li> <b>field_readcount</b>: The number of values which should be read.
The special value TIFF_VARIABLE (-1) indicates that a variable number of
values may be read. The special value TIFFTAG_SPP (-2) indicates that there
should be one value for each sample as defined by TIFFTAG_SAMPLESPERPIXEL.
The special value TIFF_VARIABLE2 (-3) is presumably similar to TIFF_VARIABLE
though I am not sure what the distinction in behaviour is. This field
is TIFF_VARIABLE for variable length ascii fields.<p>
<li> <b>field_writecount</b>: The number of values which should be written.
Generally the same as field_readcount. A few built-in exceptions exist, but
I haven't analysed why they differ. <p>
<li> <b>field_type</b>: Type of the field. One of TIFF_BYTE, TIFF_ASCII,
TIFF_SHORT, TIFF_LONG, TIFF_RATIONAL, TIFF_SBYTE, TIFF_UNDEFINED,
TIFF_SSHORT, TIFF_SLONG, TIFF_SRATIONAL, TIFF_FLOAT, TIFF_DOUBLE or
TIFF_IFD. Note that some fields can support more than one type (for
instance short and long). These fields should have multiple TIFFFieldInfos.
<p>
<li> <b>field_bit</b>: Built-in tags stored in special fields in the
TIFF structure have assigned field numbers to distinguish them (ie.
FIELD_SAMPLESPERPIXEL). New tags should generally just use
FIELD_CUSTOM indicating they are stored in the generic tag list.<p>
<li> <b>field_oktochange</b>: TRUE if it is OK to change this tag value
while an image is being written. FALSE for stuff that must be set once
and then left unchanged (like ImageWidth, or PhotometricInterpretation for
instance).<p>
<li> <b>field_passcount</b>: If TRUE, then the count value must be passed
in TIFFSetField(), and TIFFGetField(), otherwise the count is not required.
This should generally be TRUE for non-ascii variable count tags unless
the count is implicit (such as with the colormap).<p>
<li> <b>field_name</b>: A name for the tag. Normally mixed case (studly caps)
like "StripByteCounts" and relatively short. <p>
</ul>
A TIFFFieldInfo definition exists for each built-in tag in the tif_dirinfo.c
file. Some tags which support multiple data types have more than one
definition, one per data type supported. <p>
Various functions exist for getting the internal TIFFFieldInfo definitions,
including _TIFFFindFieldInfo(), and _TIFFFindFieldInfoByName(). See
tif_dirinfo.c for details. There must be some mechanism to get the whole
list, though I don't see it off hand.<p>
<h2>Default Tag Auto-registration</h2>
In libtiff 3.6.0 a new mechanism was introduced allowing libtiff to
read unrecognised tags automatically. When an unknown tags is encountered,
it is automatically internally defined with a default name and a type
derived from the tag value in the file. Applications only need to predefine
application specific tags if they need to be able to set them in a file, or
if particular calling conventions are desired for TIFFSetField() and
TIFFGetField().<p>
When tags are autodefined like this the <b>field_readcount</b> and
<b>field_writecount</b> values are always TIFF_VARIABLE. The
<b>field_passcount</b> is always TRUE, and the <b>field_bit</b> is
FIELD_CUSTOM. The field name will be "Tag %d" where the %d is the tag
number.<p>
<h2>Defining Application Tags</h2>
For various reasons, it is common for applications to want to define
their own tags to store information outside the core TIFF specification.
This is done by calling TIFFMergeFieldInfo() with one or more TIFFFieldInfos.
<p>
The libgeotiff library provides geospatial information extentions within
a TIFF file. First, a set of TIFFFieldInfo's is prepared with information
on the new tags:<p>
<pre>
static const TIFFFieldInfo xtiffFieldInfo[] = {
/* XXX Insert Your tags here */
{ TIFFTAG_GEOPIXELSCALE, -1,-1, TIFF_DOUBLE, FIELD_CUSTOM,
TRUE, TRUE, "GeoPixelScale" },
{ TIFFTAG_GEOTRANSMATRIX, -1,-1, TIFF_DOUBLE, FIELD_CUSTOM,
TRUE, TRUE, "GeoTransformationMatrix" },
{ TIFFTAG_GEOTIEPOINTS, -1,-1, TIFF_DOUBLE, FIELD_CUSTOM,
TRUE, TRUE, "GeoTiePoints" },
{ TIFFTAG_GEOKEYDIRECTORY, -1,-1, TIFF_SHORT, FIELD_CUSTOM,
TRUE, TRUE, "GeoKeyDirectory" },
{ TIFFTAG_GEODOUBLEPARAMS, -1,-1, TIFF_DOUBLE, FIELD_CUSTOM,
TRUE, TRUE, "GeoDoubleParams" },
{ TIFFTAG_GEOASCIIPARAMS, -1,-1, TIFF_ASCII, FIELD_CUSTOM,
TRUE, FALSE, "GeoASCIIParams" }
};
</pre>
In order to define the tags, we call TIFFMergeFieldInfo() on the
desired TIFF handle with the list of TIFFFieldInfos.<p>
<pre>
#define N(a) (sizeof (a) / sizeof (a[0]))
/* Install the extended Tag field info */
TIFFMergeFieldInfo(tif, xtiffFieldInfo, N(xtiffFieldInfo));
</pre>
The tags need to be defined for each TIFF file opened - and when reading
they should be defined before the tags of the file are read, yet a valid
TIFF * is needed to merge the tags against. In order to get them
registered at the appropriate part of the setup process, it is necessary
to register our merge function as an extender callback with libtiff.
This is done with TIFFSetTagExtender(). We also keep track of the
previous tag extender (if any) so that we can call it from our extender
allowing a chain of customizations to take effect. <P>
<pre>
static TIFFExtendProc _ParentExtender = NULL;
static
void _XTIFFInitialize(void)
{
static int first_time=1;
if (! first_time) return; /* Been there. Done that. */
first_time = 0;
/* Grab the inherited method and install */
_ParentExtender = TIFFSetTagExtender(_XTIFFDefaultDirectory);
}
</pre>
The extender callback is looks like this. It merges in our new fields
and then calls the next extender if there is one in effect.<p>
<pre>
static void
_XTIFFDefaultDirectory(TIFF *tif)
{
/* Install the extended Tag field info */
TIFFMergeFieldInfo(tif, xtiffFieldInfo, N(xtiffFieldInfo));
/* Since an XTIFF client module may have overridden
* the default directory method, we call it now to
* allow it to set up the rest of its own methods.
*/
if (_ParentExtender)
(*_ParentExtender)(tif);
}
</pre>
The above approach ensures that our new definitions are used when reading
or writing any TIFF file. However, since on reading we already have
default definitions for tags, it is usually not critical to pre-define them.
If tag definitions are only required for writing custom tags, you can just
call TIFFMergeFieldInfo() before setting new tags. The whole extender
architecture can then be avoided.<p>
<A NAME=AddingTags><P><H2>Adding New Builtin Tags</H2></A>
A similar approach is taken to the above. However, the TIFFFieldInfo
should be added to the tiffFieldInfo[] list in tif_dirinfo.c. Ensure that
new tags are added in sorted order by the tag number.<p>
Normally new built-in tags should be defined with FIELD_CUSTOM; however, if
it is desirable for the tag value to have it's own field in the TIFFDirectory
structure, then you will need to #define a new FIELD_ value for it, and
add appropriate handling as follows:
<OL>
<LI>Define the tag in <B>tiff.h</B>.
<LI>Add a field to the directory structure in <B>tif_dir.h</B>
and define a <TT>FIELD_*</TT> bit (also update the definition of
<TT>FIELD_CODEC</TT> to reflect your addition).
<LI>Add an entry in the <TT>TIFFFieldInfo</TT> array defined at the top of
<B>tif_dirinfo.c</B>.
Note that you must keep this array sorted by tag
number and that the widest variant entry for a tag should come
first (e.g. <TT>LONG</TT> before <TT>SHORT</TT>).
<LI>Add entries in <TT>_TIFFVSetField()</TT> and <TT>_TIFFVGetField()</TT>
for the new tag.
<LI>(<I>optional</I>) If the value associated with the tag is not a scalar value
(e.g. the array for <TT>TransferFunction</TT>) and requires
special processing,
then add the appropriate code to <TT>TIFFReadDirectory()</TT> and
<TT>TIFFWriteDirectory()</TT>. You're best off finding a similar tag and
cribbing code.
<LI>Add support to <TT>TIFFPrintDirectory()</TT> in <B>tif_print.c</B>
to print the tag's value.
</OL>
<P>
If you want to maintain portability, beware of making assumptions
about data types. Use the typedefs (<TT>uint16</TT>, etc. when dealing with
data on disk and <TT>t*_t</TT> when stuff is in memory) and be careful about
passing items through printf or similar vararg interfaces.
<A NAME=AddingCODECTags><P><H2>Adding New Codec-private Tags</H2></A>
To add tags that are meaningful <EM>only when a particular compression
algorithm is used</EM> follow these steps:
<OL>
<LI>Define the tag in <B>tiff.h</B>.
<LI>Allocate storage for the tag values in the private state block of
the codec.
<LI>Insure the state block is created when the codec is initialized.
<LI>At <TT>TIFFInitfoo</TT> time override the method pointers in the
TIFF structure
for getting, setting and printing tag values. For example,
<PRE>
sp->vgetparent = tif->tif_vgetfield;
tif->tif_vgetfield = fooVGetField; /* hook for codec tags */
sp->vsetparent = tif->tif_vsetfield;
tif->tif_vsetfield = fooVSetField; /* hook for codec tags */
tif->tif_printdir = fooPrintDir; /* hook for codec tags */
</PRE>
(Actually you may decide not to override the
<TT>tif_printdir</TT> method, but rather just specify it).
<LI>Create a private <TT>TIFFFieldInfo</TT> array for your tags and
merge them into the core tags at initialization time using
<TT>_TIFFMergeFieldInfo</TT>; e.g.
<PRE>
_TIFFMergeFieldInfo(tif, fooFieldInfo, N(fooFieldInfo));
</PRE>
(where <TT>N</TT> is a macro used liberaly throughout the distributed code).
<LI>Fill in the get and set routines. Be sure to call the parent method
for tags that you are not handled directly. Also be sure to set the
<TT>FIELD_*</TT> bits for tags that are to be written to the file. Note that
you can create ``pseudo-tags'' by defining tags that are processed
exclusively in the get/set routines and never written to file (see
the handling of <TT>TIFFTAG_FAXMODE</TT> in <B>tif_fax3.c</B>
for an example of this).
<LI>Fill in the print routine, if appropriate.
</OL>
Note that space has been allocated in the <TT>FIELD_*</TT> bit space for
codec-private tags. Define your bits as <TT>FIELD_CODEC+<offset></TT> to
keep them away from the core tags. If you need more tags than there
is room for, just increase <TT>FIELD_SETLONGS</TT> at the top of
<B>tiffiop.h</B>.

This chapter contains step-by-step instructions on how to configure
and build the TIFF software distribution. The software is most
easily built on a UNIX system, but with a little bit of work it can
easily be built and used on other non-UNIX platforms.
<hr>
<a name="CMake" id="CMAKE"></a>
<h2>Building on all systems with CMake</h2> CMake may be used to
generate build files for most common build systems and IDEs, and
supports all UNIX-like systems as well as Windows. See
the <a href="http://www.cmake.org/">CMake website</a> for further
details. To build the software on you need to first run
<tt>cmake</tt> to configure the build and generate the system-specific
build files. This reads the top-level <tt>CMakeLists.txt</tt> file,
which probes the target system for necessary tools and functions,
checks any options you specified to configure the build, and then
outputs build files configured for your system. If using <tt>Unix
Makefiles</tt>, once configuration is done, you simply
run <tt>make</tt> (or <tt>gmake</tt>) to build the software and
then <tt>make install</tt> to do the installation. For other build
systems, you do the equivalent steps with the tool for that system.
For example, on any UNIX system:
<div style="margin-left: 2em">
<pre>
% <b>cd ./tiff-4.0.5</b>
% <b>cmake</b>
<i>...lots of messages...</i>
% <b>make</b>
<i>...lots of messages...</i>
% <b>make test</b>
<i>...lots of messages...</i>
# <b>make install</b>
</pre></div>
Building is dependent on a <tt>make</tt> utility and a C
(and optionally a C++ compiler), so you will need these tools.
<p>In general, the software is designed such that the following
targets will always be available</p>
<div style="margin-left: 2em">
<pre>
make [all] build stuff
make test run the test suite
make install build and install stuff
make clean remove object files, executables and cruft
</pre></div>
<a name="CMakeBuildTrees" id= "CMakeBuildTrees"></a>
<hr width="65%" align="right">
<h3>Build Trees</h3>
There are two schemes for configuring and building the software. If
you intend to build the software for only one target system, you
can configure the software so that it is built in the same
directories as the source code.
<div style="margin-left: 2em">
<pre>
% <b>gzip -dc tiff-4.0.5.tar.gz | tar -xf -</b>
% <b>cd ./tiff-4.0.5</b>
% <b>cmake</b>
% <b>make</b>
% <b>make test</b>
% <b>make install</b>
</pre></div>
<p>Otherwise, you can configure a build tree that is parallel to
the source tree hierarchy (or in some completely different place)
but which contains only configured files and files created during
the build procedure.</p>
<div style="margin-left: 2em">
<pre>
% <b>gzip -dc tiff-4.0.5.tar.gz | tar -xf -</b>
% <b>mkdir tiff-4.0.5-build</b>
% <b>cd ./tiff-4.0.5-build</b>
% <b>cmake ../tiff-4.0.5</b>
% <b>make</b>
% <b>make test</b>
% <b>make install</b>
</pre></div>
This second scheme is useful for:
<ul>
<li>building multiple targets from a single source tree</li>
<li>building from a read-only source tree (e.g. if you receive the
distribution on CD-ROM)</li>
<li>sharing the source files via a network, but building on
multiple systems</li>
<li>keeping the source tree clean
(unlike <tt>autoconf</tt>, <tt>cmake</tt> does not provide
a <tt>distclean</tt> target, so out of source builds are
recommended)</li>
</ul>
<a name="CMakeGenerators" id= "CMakeGenerators"></a>
<hr width="65%" align="right">
<h3>Generators</h3> The default generator for UNIX is <tt>Unix
Makefiles</tt>, and on Windows is <tt>NMake Makefiles</tt> or MSBuild
depending upon the setup. Run <b>cmake --help</b> to list all the
generators available for your platform. For example, to use the Ninja
<a href="https://martine.github.io/ninja/">build system</a> on UNIX or
Windows:
<pre>
<b>cmake -G Ninja</b>
<b>cmake --build .</b>
<b>ctest -V</b>
<b>cmake --build . --target install</b>
</pre>
<p>Note that <b>cmake --build .</b> is a build-system-independent way
of building a target; you can always use the build system directly.</p>
<p>Alternatively, using the MSBuild system on Windows (64-bit Release
build with VS2013):
</p>
<pre>
<b>cmake -G "Visual Studio 12 2013 Win64"</b>
<b>cmake --build . --config Release</b>
<b>ctest -V -C Release</b>
<b>cmake --build . --config Release --target install</b>
</pre>
With the above configuration, it's also possible to open the generated
solution file with the Visual Studio IDE as well as building on the
command-line.
<a name="CMakeConfigOptions" id="CMakeConfigOptions"></a>
<hr width="65%" align="right">
<h3>Configuration Options</h3>
The configuration process is critical to the proper compilation,
installation, and operation of the
software. The <tt>CMakeLists.txt</tt> script runs a series of tests to
decide whether or not the target system supports required
functionality and, if it does not, whether it can emulate or
workaround the missing functions. After running <tt>cmake</tt>, check
the <tt>CMakeCache.txt</tt> file; this contains all the results of the
checks performed and the options set by the user. If <tt>cmake</tt>
failed to run, check <tt>CMakeFiles/CMakeOutput.log</tt>
and <tt>CMakeFiles/CMakeError.log</tt>; these should record the error
which caused the failure.
<p>A second function of the configure script is to set the default
configuration parameters for the software. Of particular note are the
directories where the software is to be installed. By default the
software is installed in the <b>/usr/local</b> hierarchy. To change
this behaviour the appropriate parameters can be specified on the
command line. Run <b>cmake --help</b> to get a full list of possible
options, and <b>cmake -LH</b> to list all the configurable options for
this software package, or <b>cmake -LAH</b> to show all advanced
options in addition. Standard installation related options are shown
below.</p>
<pre>
<tt>
Installation directories:
CMAKE_INSTALL_PREFIX

<h3>Configuring Optional Packages/Support</h3>
The TIFF software comes with several packages that are installed
only as needed, or only if specifically configured at the time the
configure script is run. Packages can be configured via the
<b>cmake</b> commandline parameters.
<dl>
<dt><i>Static/Shared Objects Support</i></dt>
<dd><tt>BUILD_SHARED_LIBS[=ON|OFF] build shared
libraries [default=ON]</tt><br>
<p>This option controls whether or not to configure the software
to build a shared and static binaries for the TIFF library. Use of
shared libraries can significantly reduce the disk space needed for
users of the TIFF software. If shared libraries are not used then
the code is statically linked into each application that uses it.
</p>
<p><tt>ld-version-script[=ON|OFF] Enable linker version
script (default is ON)</tt></p>
<p>Add shared library symbol versioning on ELF-based systems (e.g.
Linux and FreeBSD) which use the GNU linker. This is needed if
several major versions of libtiff might be loaded at once into the
same program.</p>
</dd>
<dt><i>JPEG Support</i></dt>
<dd><tt>jpeg[=ON|OFF] enable IJG JPEG
library usage (required for JPEG compression, enabled by default)<br>
JPEG_INCLUDE_DIR=DIR location of IJG
JPEG library headers<br>
JPEG_LIBRARY=DIR location of IJG JPEG
library binary)</tt></dd>
<dd>The <tt>JPEG</tt> package enables support for the handling of
TIFF images with JPEG-encoded data. Support for JPEG-encoded data
requires the Independent JPEG Group (IJG) <tt>libjpeg</tt>
distribution; this software is available at <a href=
"http://www.ijg.org/">http://www.ijg.org/</a>. <b>cmake</b>
script automatically tries to search for a working IJG JPEG
installation. If it fails to find library, JPEG support will be
automatically disabled. If you want specify the exact paths to
library binary and headers, use above options for that.</dd>
<dt><i>ZIP Support</i></dt>
<dd>The <tt>ZIP</tt> support enables support for the handling of TIFF
images with deflate-encoded data (enabled by default if
available). Support for deflate-encoded data requires the freely
available <tt>zlib</tt> distribution written by Jean-loup Gailly and
Mark Adler; this software is available at <a href=
"http://www.zlib.org/">http://www.zlib.org/</a>.</dd>

<h2>Building on a UNIX System with Autoconf</h2>
To build the software on a UNIX system you need to first run the
configure shell script that is located in the top level of the
source directory. This script probes the target system for
necessary tools and functions and constructs a build environment in
which the software may be compiled. Once configuration is done, you
simply run <tt>make</tt> (or <tt>gmake</tt>) to build the software
and then <tt>make install</tt> to do the installation; for example:
<div style="margin-left: 2em">
<pre>
% <b>cd ./tiff-4.0.5</b>
% <b>./configure</b>
<i>...lots of messages...</i>
% <b>make</b>
<i>...lots of messages...</i>
% <b>make check</b>
<i>...lots of messages...</i>
# <b>make install</b>
</pre></div>
Supplied makefiles are dependent on a <tt>make</tt> utility and a C
(and optionally a C++ compiler), so you will need these tools.
<p>In general, the software is designed such that the following
should be ``<i>make-able</i>'' in each directory:</p>
<div style="margin-left: 2em">
<pre>
make [all] build stuff
make check run the test suite
make install build and install stuff
make clean remove object files, executables and cruft
make distclean remove everything, that can be recreated
</pre></div>
Note that after running "<tt>make distclean</tt>" the
<tt>configure</tt> script must be run again to create the Makefiles
and other make-related files. <a name="BuildTrees" id=
"BuildTrees"></a>
<hr width="65%" align="right">
<h3>Build Trees</h3>
There are two schemes for configuring and building the software. If
you intend to build the software for only one target system, you
can configure the software so that it is built in the same
directories as the source code.
<div style="margin-left: 2em">
<pre>
% <b>gzip -dc tiff-4.0.5.tar.gz | tar -xf -</b>
% <b>cd ./tiff-4.0.5</b>
% <b>./configure</b>
% <b>make</b>
% <b>make check</b>
% <b>make install</b>
</pre></div>
<p>Otherwise, you can configure a build tree that is parallel to
the source tree hierarchy (or in some completely different place)
but which contains only configured files and files created during
the build procedure.</p>
<div style="margin-left: 2em">
<pre>
% <b>gzip -dc tiff-4.0.5.tar.gz | tar -xf -</b>
% <b>mkdir tiff-4.0.5-build</b>
% <b>cd ./tiff-4.0.5-build</b>
% <b>../tiff-4.0.5/configure</b>
% <b>make</b>
% <b>make check</b>
% <b>make install</b>
</pre></div>
This second scheme is useful for:
<ul>
<li>building multiple targets from a single source tree</li>
<li>building from a read-only source tree (e.g. if you receive the
distribution on CD-ROM)</li>
<li>sharing the source files via a network, but building on
multiple systems</li>
</ul>
<a name="ConfigOptions" id="ConfigOptions"></a>
<hr width="65%" align="right">
<h3>Configuration Options</h3>
The configuration process is critical to the proper compilation,
installation, and operation of the software. The configure script
runs a series of tests to decide whether or not the target system
supports required functionality and, if it does not, whether it can
emulate or workaround the missing functions. This procedure is
fairly complicated and, due to the nonstandard nature of most UNIX
systems, prone to error. The first time that you configure the
software for use you should check the output from the configure
script and look for anything that does not make sense for your
system.
<p>A second function of the configure script is to set the default
configuration parameters for the software. Of particular note are
the directories where the software is to be installed. By default
the software is installed in the <b>/usr/local</b> hierarchy. To
change this behaviour the appropriate parameters can be specified
on the command line to configure. Run <b>./configure --help</b> to
get a full list of possible options. Standard installation related
options are shown below.</p>
<pre>
<tt>
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc. You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]

<h3>Configuring Optional Packages/Support</h3>
The TIFF software comes with several packages that are installed
only as needed, or only if specifically configured at the time the
configure script is run. Packages can be configured via the
<b>configure</b> script commandline parameters.
<dl>
<dt><i>Static/Shared Objects Support</i></dt>
<dd><tt>--enable-shared[=PKGS] build shared
libraries [default=yes]<br>
--enable-static[=PKGS] build static
libraries [default=yes]</tt>
<p>These options control whether or not to configure the software
to build a shared and static binaries for the TIFF library. Use of
shared libraries can significantly reduce the disk space needed for
users of the TIFF software. If shared libraries are not used then
the code is statically linked into each application that uses it.
By default both types of binaries is configured.</p>
<p>
<tt>--enable-rpath Enable
runtime linker paths (-R libtool option)</tt></p>
<p>Add library directories (see other options below) to the TIFF
library run-time linker path.</p>
<p><tt>--enable-ld-version-script Enable linker version
script (default is disabled)</tt></p>
<p>Add shared library symbol versioning on ELF-based systems (e.g.
Linux and FreeBSD) which use the GNU linker. This is needed if
several major versions of libtiff might be loaded at once into the
same program.</p>
</dd>
<dt><i>JPEG Support</i></dt>
<dd><tt>--disable-jpeg disable IJG JPEG
library usage (required for JPEG compression, enabled by default)
--with-jpeg-include-dir=DIR location of IJG
JPEG library headers
--with-jpeg-lib-dir=DIR location of IJG JPEG
library binary)</tt></dd>
<dd>The <tt>JPEG</tt> package enables support for the handling of
TIFF images with JPEG-encoded data. Support for JPEG-encoded data
requires the Independent JPEG Group (IJG) <tt>libjpeg</tt>
distribution; this software is available at <a href=
"http://www.ijg.org/">http://www.ijg.org/</a>. <b>configure</b>
script automatically tries to search for a working IJG JPEG
installation. If it fails to find library, JPEG support will be
automatically disabled. If you want specify the exact paths to
library binary and headers, use above switches for that.</dd>
<dt><i>ZIP Support</i></dt>
<dd>The <tt>ZIP</tt> support enables support for the handling of
TIFF images with deflate-encoded data. Support for deflate-encoded
data requires the freely available <tt>zlib</tt> distribution
written by Jean-loup Gailly and Mark Adler; this software is
available at <a href=
"http://www.zlib.org/">http://www.zlib.org/</a>. If ZIP support is
enabled the <tt>DIRS_LIBINC</tt> and <tt>DIR_GZLIB</tt> parameters
should also be set (see below). By default this package is not
configured.</dd>

<h2>Building the Software under Windows 2000/XP/7/8/10 with nmake</h2>
With Microsoft Visual C++ installed, and properly configured for
commandline use (you will likely need to source VCVARS32.BAT in
AUTOEXEC.bAT or somewhere similar) you should be able to use the
provided <tt>makefile.vc</tt>.
<p>The source package is delivered using Unix line termination
conventions, which work with MSVC but do not work with Windows
'notepad'. If you use unzip from the <a href=
"http://www.info-zip.org/pub/infozip/">Info-Zip</a> package, you
can extract the files using Windows normal line termination
conventions with a command similar to:</p>
<pre>
unzip -aa -a tiff-4.0.5.zip
</pre>
<p>By default the nmake-based libtiff build does not depend on any
additional libraries. Normally libtiff should be built with at least
JPEG and ZIP support so that it can open JPEG and ZIP-compressed TIFF
files. In order to add additional libraries (e.g. libjpeg, zlib,
jbigkit), build those libraries according to their own particular
build instructions, and then edit 'nmake.opt' (using a capable
plain-text editor) to enable use of the libraries, including
specifying where the libraries are installed. It is also necessary to
edit libtiff/tiffconf.vc.h to enable the related configuration defines
(<em>JPEG_SUPPORT</em>, <em>OJPEG_SUPPORT</em>, <em>PIXARLOG_SUPPORT</em>,
<em>ZIP_SUPPORT</em>), or to disable features which are normally
included by default. Ignore the comment at the top of the
libtiff/tiffconf.vc.h file which says that it has no influence on the
build, because the statement is not true for Windows. Please note that
the nmake build copies tiffconf.vc.h to tiffconf.h, and copies
tif_config.vc.h to tif_config.h, overwriting any files which may be
present. Likewise, the 'nmake clean' step removes those files.</p>
<p>To build using the provided makefile.vc you may use:</p>
<pre>
C:\tiff-4.0.5> nmake /f makefile.vc clean
C:\tiff-4.0.5> nmake /f makefile.vc
or (the hard way)
C:\tiff-4.0.5> cd port
C:\tiff-4.0.5\port> nmake /f makefile.vc clean
C:\tiff-4.0.5\port> nmake /f makefile.vc
C:\tiff-4.0.5> cd ../libtiff
C:\tiff-4.0.5\libtiff> nmake /f makefile.vc clean
C:\tiff-4.0.5\libtiff> nmake /f makefile.vc
C:\tiff-4.0.5\libtiff> cd ..\tools
C:\tiff-4.0.5\tools> nmake /f makefile.vc clean
C:\tiff-4.0.5\tools> nmake /f makefile.vc
</pre>
<p>This will build the library
file <tt>libtiff\libtiff\libtiff.lib</tt>.</p>
<p>The makefile also builds a DLL (libtiff.dll) with an associated
import library (libtiff_i.lib). Any builds using libtiff will need to
include the LIBTIFF\LIBTIFF directory in the include path.</p>
<p>The <tt>libtiff\tools\makefile.vc</tt> should build .exe's for
all the standard TIFF tool programs.</p>

<h2>Building the Software on a VMS System</h2>
The VMS port was done by Karsten Spang (<a href=
"mailto:krs@kampsax.dk">krs@kampsax.dk</a>), who also "sort of"
maintains it. The VMS specific files are not in the main
directories. Instead they are placed under
<tt>[.CONTRIB.VMS...]</tt> in the distribution tree. Installation:
It is assumed that you have unpacked the tar file into a VMS
directory tree, in this text called DISK:[TIFF].
<ol>
<li>Move the VMS specific files to their proper directories.
<pre>
$ SET DEFAULT DISK:[TIFF.CONTRIB.VMS]
$ RENAME [.LIBTIFF]*.* [-.-.LIBTIFF]
$ RENAME [.TOOLS]*.* [-.-.TOOLS]
</pre></li>
<li>Compile the library.
<pre>
$ SET DEFAULT DISK:[TIFF.LIBTIFF]
$ @MAKEVMS
</pre></li>
<li>Compile the tools.
<pre>
$ SET DEFAULT DISK:[TIFF.TOOLS]
$ @MAKEVMS
</pre></li>
<li>Define the programs.

You will want to add these lines to your <tt>LOGIN.COM</tt> file,
after changing the name of the directory that you have used on your
machine.
<p>This release has been tested on OpenVMS/VAX 5.5-2, using VAX C
3.2. A previous release was tested under OpenVMS/AXP ?.? using DEC
C ?.?, it is believed that this release as well works on AXP. The
code contains some GNU C specific things. This does *not* imply,
however, that the VAX/GCC configuration has been tested, *it has
not*.</p>
<p>The command procedures (<tt>MAKEVMS.COM</tt>) for building the
library and tools, is believed to choose the correct options for
the VAX and AXP cases automatically.</p>
<p>On the AXP, IEEE floating point is used by default. If you want
VAX floating point, remove the <tt>/FLOAT=IEEE_FLOAT</tt>
qualifier, and change <tt>HAVE_IEEEFP=1</tt> to
<tt>HAVE_IEEEFP=0</tt> in the <tt>MAKEVMS.COM</tt> files in both
the <b>libtiff</b> and <b>tools</b> directories.</p>
<h3>Compiling your own program on a VMS system:</h3>
When compiling a source file in which you <tt>"#include
<tiffio.h>"</tt>, use the following command
<pre>
$ CC/INCLUDE=DISK:[TIFF.LIBTIFF]
</pre>
This ensures that the header file is found. On the AXP, also add
<tt>/FLOAT=IEEE_FLOAT</tt> (if used when building the library).
<h3>Linking your own program to the TIFF library on a VMS
system:</h3>
You can link to the library in two ways: Either using the shareable
library, or using the object library. On the VAX these
possibilities are:
<ol>
<li>Using the shareable TIFF library.
<pre>
$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS,SYS$INPUT:/OPTIONS
SYS$SHARE:VAXCRTL/SHAREABLE
</pre></li>
<li>Using the TIFF object library.
<pre>
$ LINK MY_PROGRAM, -
DISK:[TIFF.LIBTIFF]TIFF/LIBRARY/INCLUDE=(TIF_FAX3SM,TIF_CODEC), -
SYS$INPUT:/OPTIONS
SYS$SHARE:VAXCRTL/SHAREABLE
</pre></li>
</ol>
On AXP (and possibly also using DEC C on VAX) the corresponding
commands are
<ol>
<li>Using the shareable TIFF library.
<pre>
$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS
</pre></li>
<li>Using the TIFF object library.
<pre>
$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/LIBRARY
</pre></li>
</ol>
Method 1 uses the shortest link time and smallest <tt>.EXE</tt>
files, but it requires that <tt>TIFFSHR</tt> is defined as above at
link time and <strong>at run time</strong>. Using the compilation
procedure above, the tools are linked in this way.
<p>Method 2 gives somewhat longer link time and larger
<tt>.EXE</tt> files, but does not require <tt>TIFFSHR</tt> to be
defined. This method is recommended if you want to run your program
on another machine, and for some reason don't want to have the
library on that machine. If you plan to have more than one program
(including the tools) on the machine, it is recommended that you
copy the library to the other machine and use method 1.</p>
<hr>
<a name="Other" id="Other"></a>
<h2>Building the Software on Other Systems</h2>
This section contains information that might be useful if you are
working on a non-UNIX system that is not directly supported. All
library-related files described below are located in the
<b>libtiff</b> directory.
<p>The library requires two files that are generated
<i>on-the-fly</i>. The file <b>tif_fax3sm.c</b> has the state
tables for the Group 3 and Group 4 decoders. This file is generated
by the <tt>mkg3states</tt> program on a UNIX system; for
example,</p>
<div style="margin-left: 2em">
<pre>
<tt>
cd libtiff
cc -o mkg3states mkg3states.c
rm -f tif_fax3sm.c
./mkg3states -c const tif_fax3sm.c
</tt>
</pre></div>
The <tt>-c</tt> option can be used to control whether or not the
resutling tables are generated with a <tt>const</tt> declaration.
The <tt>-s</tt> option can be used to specify a C storage class for
the table declarations. The <tt>-b</tt> option can be used to force
data values to be explicitly bracketed with ``{}'' (apparently
needed for some MS-Windows compilers); otherwise the structures are
emitted in as compact a format as possible. Consult the source code
for this program if you have questions.
<p>The second file required to build the library, <b>version.h</b>,
contains the version information returned by the
<tt>TIFFGetVersion</tt> routine. This file is built on most systems
using the <tt>mkversion</tt> program and the contents of the
<tt>VERSION</tt> and <tt>tiff.alpha</tt> files; for example,</p>
<div style="margin-left: 2em">
<pre>
cd libtiff
cc -o mkversion mkversion.c
rm -f version.h
./mkversion -v ../VERSION -a ../dist/tiff.alpha version.h
</pre></div>
<p>Otherwise, when building the library on a non-UNIX system be
sure to consult the files <b>tiffcomp.h</b> and <b>tiffconf.h</b>.
The former contains system compatibility definitions while the
latter is provided so that the software configuration can be
controlled on systems that do not support the make facility for
building the software.</p>
<p>Systems without a 32-bit compiler may not be able to handle some
of the codecs in the library; especially the Group 3 and 4 decoder.
If you encounter problems try disabling support for a particular
codec; consult the <a href=
"internals.html#Config">documentation</a>.</p>
<p>Programs in the tools directory are written to assume an ANSI C
compilation environment. There may be a few POSIX'isms as well. The
code in the <b>port</b> directory is provided to emulate routines
that may be missing on some systems. On UNIX systems the
<tt>configure</tt> script automatically figures out which routines
are not present on a system and enables the use of the equivalent
emulation routines from the <b>port</b> directory. It may be
necessary to manually do this work on a non-UNIX system. <a name=
"Testing" id="Testing"></a></p>
<hr>
<h2>Checking out the Software</h2>
<p>Assuming you have working versions of <tt>tiffgt</tt> and
<tt>tiffsv</tt>, you can just use them to view any of the sample
images available for testing (see the <a href="images.html">section
on obtaining the test images</a>). Otherwise, you can do a cursory
check of the library with the <tt>tiffcp</tt> and <tt>tiffcmp</tt>
programs. For example,</p>
<div style="margin-left: 2em">
<pre>
tiffcp -lzw cramps.tif x.tif
tiffcmp cramps.tif x.tif
</pre></div>
<p>(<tt>tiffcmp</tt> should be silent if the files compare
correctly). <a name="TOC" id="TOC"></a></p>

<p>
This software provides support for the <i>Tag Image File Format</i> (TIFF),
a widely used format for storing image data. The latest version of
the TIFF specification is <a href="document.html">available on-line</a>
in several different formats.
</p>
<p>
Included in this software distribution is a library, libtiff, for
reading and writing TIFF, a small collection of tools for doing
simple manipulations of TIFF images, and documentation on the
library and tools. Libtiff is a portable software, it was built
and tested on various systems: UNIX flavors (Linux, BSD, Solaris,
MacOS X), Windows, and OpenVMS. It should be possible to port
libtiff and additional tools on other OSes.
</p>
<p>
The library, along with associated tool programs, should handle most of
your needs for reading and writing TIFF images on 32- and 64-bit
machines.
</p>
<p>
The software was originally authored and maintained by Sam Leffler
but has been maintained by a cast of others since 1999.
</p>
<p>
Questions should be sent to the TIFF mailing list:
<a href="mailto:tiff@lists.maptools.org">tiff@lists.maptools.org</a>, with
a subscription interface at
<a href="http://lists.maptools.org/mailman/listinfo/tiff">http://lists.maptools.org/mailman/listinfo/tiff</a>.
</p>

The persons currently actively maintaining and releasing libtiff
are <a href="mailto:even.rouault@spatialys.com">Even Rouault</a>

Modifying The TIFF Library
</H1>
<P>
This chapter provides information about the internal structure of
the library, how to control the configuration when building it, and
how to add new support to the library.
The following sections are found in this chapter:
<UL>
<LI><A HREF=#Config>Library Configuration</A>
<LI><A HREF=#Portability>General Portability Comments</A>
<LI><A HREF="#Types">Types and Portability</A>
<LI><A HREF="addingtags.html">Adding New Tags</A>
<LI><A HREF=#AddingCODECS>Adding New Builtin Codecs</A>
<LI><A HREF="addingtags.html#AddingCODECTags">Adding New Codec-private Tags</A>
<LI><A HREF=#Other>Other Comments</A>
</UL>
<A NAME="Config"><P><HR WIDTH=65% ALIGN=right><H3>Library Configuration</H3></A>
Information on compiling the library is given
<A HREF=build.html>elsewhere in this documentation</A>.
This section describes the low-level mechanisms used to control
the optional parts of the library that are configured at build
time. Control is based on
a collection of C defines that are specified either on the compiler
command line or in a configuration file such as <TT>port.h</TT>
(as generated by the <TT>configure</TT> script for UNIX systems)
or <B>tiffconf.h</B>.
<P>
Configuration defines are split into three areas:
<UL>
<LI>those that control which compression schemes are
configured as part of the builtin codecs,
<LI>those that control support for groups of tags that
are considered optional, and
<LI>those that control operating system or machine-specific support.
</UL>
<P>
If the define <TT>COMPRESSION_SUPPORT</TT> is <STRONG>not defined</STRONG>
then a default set of compression schemes is automatically
configured:
<UL>
<LI>CCITT Group 3 and 4 algorithms (compression codes 2, 3, 4, and 32771),
<LI>the Macintosh PackBits algorithm (compression 32773),
<LI>a 4-bit run-length encoding scheme from ThunderScan (compression 32809),
<LI>a 2-bit encoding scheme used by NeXT (compression 32766), and
<LI>two experimental schemes intended for images with high dynamic range
(compression 34676 and 34677).
</UL>
<P>
To override the default compression behaviour define
<TT>COMPRESSION_SUPPORT</TT> and then one or more additional defines
to enable configuration of the appropriate codecs (see the table
below); e.g.
<UL><PRE>
#define COMPRESSION_SUPPORT
#define CCITT_SUPPORT
#define PACKBITS_SUPPORT
</PRE></UL>
Several other compression schemes are configured separately from
the default set because they depend on ancillary software
packages that are not distributed with <TT>libtiff</TT>.
<P>
Support for JPEG compression is controlled by <TT>JPEG_SUPPORT</TT>.
The JPEG codec that comes with <TT>libtiff</TT> is designed for
use with release 5 or later of the Independent JPEG Group's freely
available software distribution.
This software can be retrieved from the directory
<A HREF=ftp://ftp.uu.net/graphics/jpeg>ftp.uu.net:/graphics/jpeg/</A>.
<P>
<IMG SRC="images/info.gif" ALT="NOTE: " ALIGN=left HSPACE=8>
<EM>Enabling JPEG support automatically enables support for
the TIFF 6.0 colorimetry and YCbCr-related tags.</EM>
<P>
Experimental support for the deflate algorithm is controlled by
<TT>DEFLATE_SUPPORT</TT>.
The deflate codec that comes with <TT>libtiff</TT> is designed
for use with version 0.99 or later of the freely available
<TT>libz</TT> library written by Jean-loup Gailly and Mark Adler.
The data format used by this library is described
in the files
<A HREF=ftp://ftp.uu.net/pub/archiving/zip/doc/zlib-3.1.doc>zlib-3.1.doc</A>,
and
<A HREF=ftp://ftp.uu.net/pub/archiving/zip/doc/deflate-1.1.doc>deflate-1.1.doc</A>,
available in the directory
<A HREF=ftp://ftp.uu.net/pub/archiving/zip/doc>ftp.uu.net:/pub/archiving/zip/doc</A>.</EM>
The library can be retried from the directory
<A HREF=ftp://ftp.uu.net/pub/archiving/zip/zlib/>ftp.uu.net:/pub/archiving/zip/zlib/</A>
(or try <A HREF=ftp://quest.jpl.nasa.gov/beta/zlib/>quest.jpl.nasa.gov:/beta/zlib/</A>).
<P>
<IMG SRC="images/warning.gif" ALT="NOTE: " ALIGN=left HSPACE=8 VSPACE=6>
<EM>The deflate algorithm is experimental. Do not expect
to exchange files using this compression scheme;
it is included only because the similar, and more common,
LZW algorithm is claimed to be governed by licensing restrictions.</EM>
<P>
By default <B>tiffconf.h</B> defines
<TT>COLORIMETRY_SUPPORT</TT>,
<TT>YCBCR_SUPPORT</TT>,
and

<A NAME="Portability"><P><HR WIDTH=65% ALIGN=right><H3>General Portability Comments</H3></A>
This software is developed on Silicon Graphics UNIX
systems (big-endian, MIPS CPU, 32-bit ints,
IEEE floating point).
The <TT>configure</TT> shell script generates the appropriate
include files and make files for UNIX systems.
Makefiles exist for non-UNIX platforms that the
code runs on -- this work has mostly been done by other people.
<P>
In general, the code is guaranteed to work only on SGI machines.
In practice it is highly portable to any 32-bit or 64-bit system and much
work has been done to insure portability to 16-bit systems.
If you encounter portability problems please return fixes so
that future distributions can be improved.
<P>
The software is written to assume an ANSI C compilation environment.
If your compiler does not support ANSI function prototypes, <TT>const</TT>,
and <TT><stdarg.h></TT> then you will have to make modifications to the
software. In the past I have tried to support compilers without <TT>const</TT>
and systems without <TT><stdarg.h></TT>, but I am
<EM>no longer interested in these
antiquated environments</EM>. With the general availability of
the freely available GCC compiler, I
see no reason to incorporate modifications to the software for these
purposes.
<P>
An effort has been made to isolate as many of the
operating system-dependencies
as possible in two files: <B>tiffcomp.h</B> and
<B>libtiff/tif_<os>.c</B>. The latter file contains
operating system-specific routines to do I/O and I/O-related operations.
The UNIX (<B>tif_unix.c</B>),
Macintosh (<B>tif_apple.c</B>),
and VMS (<B>tif_vms.c</B>)
code has had the most use;
the MS/DOS support (<B>tif_msdos.c</B>) assumes
some level of UNIX system call emulation (i.e.
<TT>open</TT>,
<TT>read</TT>,
<TT>write</TT>,
<TT>fstat</TT>,
<TT>malloc</TT>,
<TT>free</TT>).
<P>
Native CPU byte order is determined on the fly by
the library and does not need to be specified.
The <TT>HOST_FILLORDER</TT> and <TT>HOST_BIGENDIAN</TT>
definitions are not currently used, but may be employed by
codecs for optimization purposes.
<P>
The following defines control general portability:
<P>
<TABLE BORDER CELLPADDING=3 WIDTH=100%>
<TR>
<TD VALIGN=top><TT>BSDTYPES</TT></TD>
<TD>Define this if your system does NOT define the
usual BSD typedefs: <TT>u_char</TT>,
<TT>u_short</TT>, <TT>u_int</TT>, <TT>u_long</TT>.</TD>
</TR>
<TR>
<TD VALIGN=top><TT>HAVE_IEEEFP</TT></TD>
<TD>Define this as 0 or 1 according to the floating point
format suported by the machine. If your machine does
not support IEEE floating point then you will need to
add support to tif_machdep.c to convert between the
native format and IEEE format.</TD>
</TR>
<TR>
<TD VALIGN=top><TT>HAVE_MMAP</TT></TD>
<TD>Define this if there is <I>mmap-style</I> support for
mapping files into memory (used only to read data).</TD>
</TR>
<TR>
<TD VALIGN=top><TT>HOST_FILLORDER</TT></TD>
<TD>Define the native CPU bit order: one of <TT>FILLORDER_MSB2LSB</TT>
or <TT>FILLORDER_LSB2MSB</TT></TD>
</TR>
<TR>
<TD VALIGN=top><TT>HOST_BIGENDIAN</TT></TD>
<TD>Define the native CPU byte order: 1 if big-endian (Motorola)
or 0 if little-endian (Intel); this may be used
in codecs to optimize code</TD>
</TR>
</TABLE>
<P>
On UNIX systems <TT>HAVE_MMAP</TT> is defined through the running of
the <TT>configure</TT> script; otherwise support for memory-mapped
files is disabled.
Note that <B>tiffcomp.h</B> defines <TT>HAVE_IEEEFP</TT> to be
1 (<TT>BSDTYPES</TT> is not defined).
<A NAME="Types"><P><HR WIDTH=65% ALIGN=right><H3>Types and Portability</H3></A>
The software makes extensive use of C typedefs to promote portability.
Two sets of typedefs are used, one for communication with clients
of the library and one for internal data structures and parsing of the
TIFF format. There are interactions between these two to be careful
of, but for the most part you should be able to deal with portability
purely by fiddling with the following machine-dependent typedefs:

promoted to when passed by value in a function call.)
<P>
The following typedefs are used throughout the library and interfaces
to refer to certain objects whose size is dependent on the TIFF image
structure:
<P>
<TABLE BORDER CELLPADDING=3 WIDTH=100%>
<TR>
<TD WIDTH=25%>typedef unsigned int ttag_t;</TD> <TD>directory tag</TD>
</TR>
<TR>
<TD>typedef uint16 tdir_t;</TD> <TD>directory index</TD>

<TR>
<TD>typedef uint32 ttile_t;</TD> <TD>tile number</TD>
</TR>
<TR>
<TD>typedef int32 tsize_t;</TD> <TD>i/o size in bytes</TD>
</TR>
<TR>
<TD>typedef void* tdata_t;</TD> <TD>image data ref</TD>
</TR>

<TD>typedef void* thandle_t;</TD> <TD>client data handle</TD>
</TR>
<TR>
<TD>typedef int32 toff_t;</TD> <TD>file offset (should be off_t)</TD>
</TR>
<TR>
<TD>typedef unsigned char* tidata_t;</TD> <TD>internal image data</TD>
</TR>
</TABLE>
<P>
Note that <TT>tstrip_t</TT>, <TT>ttile_t</TT>, and <TT>tsize_t</TT>
are constrained to be
no more than 32-bit quantities by 32-bit fields they are stored
in in the TIFF image. Likewise <TT>tsample_t</TT> is limited by the 16-bit
field used to store the <TT>SamplesPerPixel</TT> tag. <TT>tdir_t</TT>
constrains
the maximum number of IFDs that may appear in an image and may
be an arbitrary size (without penalty). <TT>ttag_t</TT> must be either
<TT>int</TT>, <TT>unsigned int</TT>, pointer, or <TT>double</TT>
because the library uses a varargs
interface and ANSI C restricts the type of the parameter before an
ellipsis to be a promoted type. <TT>toff_t</TT> is defined as
<TT>int32</TT> because
TIFF file offsets are (unsigned) 32-bit quantities. A signed
value is used because some interfaces return -1 on error (sigh).
Finally, note that <TT>tidata_t</TT> is used internally to the library to
manipulate internal data. User-specified data references are
passed as opaque handles and only cast at the lowest layers where
their type is presumed.
<P><HR WIDTH=65% ALIGN=right><H3>General Comments</H3></A>
The library is designed to hide as much of the details of TIFF from
applications as
possible. In particular, TIFF directories are read in their entirety
into an internal format. Only the tags known by the library are
available to a user and certain tag data may be maintained that a user
does not care about (e.g. transfer function tables).
<A NAME=AddingCODECS><P><HR WIDTH=65% ALIGN=right><H3>Adding New Builtin Codecs</H3></A>
To add builtin support for a new compression algorithm, you can either
use the "tag-extension" trick to override the handling of the
TIFF Compression tag (see <A HREF=addingtags.html>Adding New Tags</A>),
or do the following to add support directly to the core library:
<OL>
<LI>Define the tag value in <B>tiff.h</B>.
<LI>Edit the file <B>tif_codec.c</B> to add an entry to the
_TIFFBuiltinCODECS array (see how other algorithms are handled).
<LI>Add the appropriate function prototype declaration to
<B>tiffiop.h</B> (close to the bottom).
<LI>Create a file with the compression scheme code, by convention files
are named <B>tif_*.c</B> (except perhaps on some systems where the
tif_ prefix pushes some filenames over 14 chars.
<LI>Edit <B>Makefile.in</B> (and any other Makefiles)
to include the new source file.
</OL>
<P>
A codec, say <TT>foo</TT>, can have many different entry points:
<PRE>
TIFFInitfoo(tif, scheme)/* initialize scheme and setup entry points in tif */
fooSetupDecode(tif) /* called once per IFD after tags has been frozen */
fooPreDecode(tif, sample)/* called once per strip/tile, after data is read,
but before the first row is decoded */
fooDecode*(tif, bp, cc, sample)/* decode cc bytes of data into the buffer */
fooDecodeRow(...) /* called to decode a single scanline */
fooDecodeStrip(...) /* called to decode an entire strip */
fooDecodeTile(...) /* called to decode an entire tile */
fooSetupEncode(tif) /* called once per IFD after tags has been frozen */
fooPreEncode(tif, sample)/* called once per strip/tile, before the first row in
a strip/tile is encoded */
fooEncode*(tif, bp, cc, sample)/* encode cc bytes of user data (bp) */
fooEncodeRow(...) /* called to decode a single scanline */
fooEncodeStrip(...) /* called to decode an entire strip */
fooEncodeTile(...) /* called to decode an entire tile */
fooPostEncode(tif) /* called once per strip/tile, just before data is written */
fooSeek(tif, row) /* seek forwards row scanlines from the beginning
of a strip (row will always be >0 and <rows/strip */
fooCleanup(tif) /* called when compression scheme is replaced by user */
</PRE>
<P>
Note that the encoding and decoding variants are only needed when
a compression algorithm is dependent on the structure of the data.
For example, Group 3 2D encoding and decoding maintains a reference
scanline. The sample parameter identifies which sample is to be
encoded or decoded if the image is organized with <TT>PlanarConfig</TT>=2
(separate planes). This is important for algorithms such as JPEG.
If <TT>PlanarConfig</TT>=1 (interleaved), then sample will always be 0.
<A NAME=Other><P><HR WIDTH=65% ALIGN=right><H3>Other Comments</H3></A>
The library handles most I/O buffering. There are two data buffers
when decoding data: a raw data buffer that holds all the data in a
strip, and a user-supplied scanline buffer that compression schemes
place decoded data into. When encoding data the data in the
user-supplied scanline buffer is encoded into the raw data buffer (from
where it is written). Decoding routines should never have to explicitly
read data -- a full strip/tile's worth of raw data is read and scanlines
never cross strip boundaries. Encoding routines must be cognizant of
the raw data buffer size and call <TT>TIFFFlushData1()</TT> when necessary.
Note that any pending data is automatically flushed when a new strip/tile is
started, so there's no need do that in the tif_postencode routine (if
one exists). Bit order is automatically handled by the library when
a raw strip or tile is filled. If the decoded samples are interpreted
by the decoding routine before they are passed back to the user, then
the decoding logic must handle byte-swapping by overriding the
<TT>tif_postdecode</TT>
routine (set it to <TT>TIFFNoPostDecode</TT>) and doing the required work
internally. For an example of doing this look at the horizontal
differencing code in the routines in <B>tif_predict.c</B>.
<P>
The variables <TT>tif_rawcc</TT>, <TT>tif_rawdata</TT>, and
<TT>tif_rawcp</TT> in a <TT>TIFF</TT> structure
are associated with the raw data buffer. <TT>tif_rawcc</TT> must be non-zero
for the library to automatically flush data. The variable
<TT>tif_scanlinesize</TT> is the size a user's scanline buffer should be. The
variable <TT>tif_tilesize</TT> is the size of a tile for tiled images. This
should not normally be used by compression routines, except where it
relates to the compression algorithm. That is, the <TT>cc</TT> parameter to the
<TT>tif_decode*</TT> and <TT>tif_encode*</TT>
routines should be used in terminating
decompression/compression. This ensures these routines can be used,
for example, to decode/encode entire strips of data.
<P>
In general, if you have a new compression algorithm to add, work from
the code for an existing routine. In particular,
<B>tif_dumpmode.c</B>
has the trivial code for the "nil" compression scheme,
<B>tif_packbits.c</B> is a
simple byte-oriented scheme that has to watch out for buffer
boundaries, and <B>tif_lzw.c</B> has the LZW scheme that has the most
complexity -- it tracks the buffer boundary at a bit level.
Of course, using a private compression scheme (or private tags) limits
the portability of your TIFF files.

Introduction to the TIFF Documentation

<P>
The following definitions are used throughout this documentation.
They are consistent with the terminology used in the TIFF 6.0 specification.
<DL>
<DT><I>Sample</I>
<DD>The unit of information stored in an image; often called a
channel elsewhere. Sample values are numbers, usually unsigned
integers, but possibly in some other format if the SampleFormat
tag is specified in a TIFF
<DT><I>Pixel</I>
<DD>A collection of one or more samples that go together.
<DT><I>Row</I>
<DD>An Nx1 rectangular collection of pixels.
<DT><I>Tile</I>
<DD>An NxM rectangular organization of data (or pixels).
<DT><I>Strip</I>
<DD>A tile whose width is the full image width.
<DT><I>Compression</I>
<DD>A scheme by which pixel or sample data are stored in
an encoded form, specifically with the intent of reducing the
storage cost.
<DT><I>Codec</I>
<DD>Software that implements the decoding and encoding algorithms
of a compression scheme.
</UL>
<P>
In order to better understand how TIFF works (and consequently this
software) it is important to recognize the distinction between the
physical organization of image data as it is stored in a TIFF and how
the data is interpreted and manipulated as pixels in an image. TIFF
supports a wide variety of storage and data compression schemes that
can be used to optimize retrieval time and/or minimize storage space.
These on-disk formats are independent of the image characteristics; it
is the responsibility of the TIFF reader to process the on-disk storage
into an in-memory format suitable for an application. Furthermore, it
is the responsibility of the application to properly interpret the
visual characteristics of the image data. TIFF defines a framework for
specifying the on-disk storage format and image characteristics with
few restrictions. This permits significant complexity that can be
daunting. Good applications that handle TIFF work by handling as wide
a range of storage formats as possible, while constraining the
acceptable image characteristics to those that make sense for the
application.

<h1>Using The TIFF Library</h1>
<p>
<tt>libtiff</tt> is a set of C functions (a library) that support
the manipulation of TIFF image files.
The library requires an ANSI C compilation environment for building
and presumes an ANSI C environment for use.
</p>
</td>
</tr>
</table>
<br>
<p>
<tt>libtiff</tt>
provides interfaces to image data at several layers of abstraction (and cost).
At the highest level image data can be read into an 8-bit/sample,
ABGR pixel raster format without regard for the underlying data organization,
colorspace, or compression scheme. Below this high-level interface
the library provides scanline-, strip-, and tile-oriented interfaces that
return data decompressed but otherwise untransformed. These interfaces
require that the application first identify the organization of stored
data and select either a strip-based or tile-based API for manipulating
data. At the lowest level the library
provides access to the raw uncompressed strips or tiles,
returning the data exactly as it appears in the file.
</p>
<p>
The material presented in this chapter is a basic introduction
to the capabilities of the library; it is not an attempt to describe
everything a developer needs to know about the library or about TIFF.
Detailed information on the interfaces to the library are given in
the <a href="http://www.simplesystems.org/libtiff/man/index.html">UNIX
manual pages</a> that accompany this software.
</p>
<p>
Michael Still has also written a useful introduction to libtiff for the
IBM DeveloperWorks site available at
<a href="http://www.ibm.com/developerworks/linux/library/l-libtiff">http://www.ibm.com/developerworks/linux/library/l-libtiff</a>.

<hr>
<h2 id="version">How to tell which version you have</h2>
<p>
The software version can be found by looking at the file named
<tt>VERSION</tt>
that is located at the top of the source tree; the precise alpha number
is given in the file <tt>dist/tiff.alpha</tt>.
If you have need to refer to this
specific software, you should identify it as:
</p>
<p style="margin-left: 40px">
<tt>TIFF <<i>version</i>> <<i>alpha</i>></tt>
</p>
<p>
where <tt><<i>version</i>></tt> is whatever you get from
<tt>"cat VERSION"</tt> and <tt><<i>alpha</i>></tt> is
what you get from <tt>"cat dist/tiff.alpha"</tt>.
</p>
<p>
Within an application that uses <tt>libtiff</tt> the <tt>TIFFGetVersion</tt>
routine will return a pointer to a string that contains software version
information.
The library include file <tt><tiffio.h></tt> contains a C pre-processor
define <tt>TIFFLIB_VERSION</tt> that can be used to check library
version compatiblity at compile time.
</p>
<hr>
<h2 id="typedefs">Library Datatypes</h2>
<p>
<tt>libtiff</tt> defines a portable programming interface through the
use of a set of C type definitions.
These definitions, defined in in the files <b>tiff.h</b> and
<b>tiffio.h</b>,
isolate the <tt>libtiff</tt> API from the characteristics
of the underlying machine.
To insure portable code and correct operation, applications that use
<tt>libtiff</tt> should use the typedefs and follow the function
prototypes for the library API.
</p>
<hr>
<h2 id="mman">Memory Management</h2>
<p>
<tt>libtiff</tt> uses a machine-specific set of routines for managing
dynamically allocated memory.
<tt>_TIFFmalloc</tt>, <tt>_TIFFrealloc</tt>, and <tt>_TIFFfree</tt>
mimic the normal ANSI C routines.
Any dynamically allocated memory that is to be passed into the library
should be allocated using these interfaces in order to insure pointer
compatibility on machines with a segmented architecture.
(On 32-bit UNIX systems these routines just call the normal <tt>malloc</tt>,
<tt>realloc</tt>, and <tt>free</tt> routines in the C library.)
</p>
<p>
To deal with segmented pointer issues <tt>libtiff</tt> also provides
<tt>_TIFFmemcpy</tt>, <tt>_TIFFmemset</tt>, and <tt>_TIFFmemmove</tt>
routines that mimic the equivalent ANSI C routines, but that are
intended for use with memory allocated through <tt>_TIFFmalloc</tt>
and <tt>_TIFFrealloc</tt>.
</p>
<hr>
<h2 id="errors">Error Handling</h2>
<p>
<tt>libtiff</tt> handles most errors by returning an invalid/erroneous
value when returning from a function call.
Various diagnostic messages may also be generated by the library.
All error messages are directed to a single global error handler
routine that can be specified with a call to <tt>TIFFSetErrorHandler</tt>.
Likewise warning messages are directed to a single handler routine
that can be specified with a call to <tt>TIFFSetWarningHandler</tt>
</p>
<hr>
<h2 id="fio">Basic File Handling</h2>
<p>
The library is modeled after the normal UNIX stdio library.
For example, to read from an existing TIFF image the
file must first be opened:
</p>
<p style="margin-left: 40px">
<tt>#include "tiffio.h"<br>
main()<br>
{<br>
TIFF* tif = TIFFOpen("foo.tif", "r");<br>
... do stuff ...<br>
TIFFClose(tif);<br>
}</tt>
</p>
<p>
The handle returned by <tt>TIFFOpen</tt> is <i>opaque</i>, that is
the application is not permitted to know about its contents.
All subsequent library calls for this file must pass the handle
as an argument.
</p>
<p>
To create or overwrite a TIFF image the file is also opened, but with
a <tt>"w"</tt> argument:
<p>
<p style="margin-left: 40px">
<tt>#include "tiffio.h"<br>
main()<br>
{<br>
TIFF* tif = TIFFOpen("foo.tif", "w");<br>
... do stuff ...<br>
TIFFClose(tif);<br>
}</tt>
</p>
<p>
If the file already exists it is first truncated to zero length.
</p>
<table>
<tr>
<td valign=top><img src="images/warning.gif" width="40" height="40" alt=""></td>
<td><i>Note that unlike the stdio library TIFF image files may not be
opened for both reading and writing;
there is no support for altering the contents of a TIFF file.</i></td>
</tr>
</table>
<p>
<tt>libtiff</tt> buffers much information associated with writing a
valid TIFF image. Consequently, when writing a TIFF image it is necessary
to always call <tt>TIFFClose</tt> or <tt>TIFFFlush</tt> to flush any
buffered information to a file. Note that if you call <tt>TIFFClose</tt>
you do not need to call <tt>TIFFFlush</tt>.
</p>
<hr>
<h2 id="dirs">TIFF Directories</h2>
<p>
TIFF supports the storage of multiple images in a single file.
Each image has an associated data structure termed a <i>directory</i>
that houses all the information about the format and content of the
image data.
Images in a file are usually related but they do not need to be; it
is perfectly alright to store a color image together with a black and
white image.
Note however that while images may be related their directories are
not.
That is, each directory stands on its own; their is no need to read
an unrelated directory in order to properly interpret the contents
of an image.
</p>
<p>
<tt>libtiff</tt> provides several routines for reading and writing
directories. In normal use there is no need to explicitly
read or write a directory: the library automatically reads the first
directory in a file when opened for reading, and directory information
to be written is automatically accumulated and written when writing
(assuming <tt>TIFFClose</tt> or <tt>TIFFFlush</tt> are called).
</p>
<p>
For a file open for reading the <tt>TIFFSetDirectory</tt> routine can
be used to select an arbitrary directory; directories are referenced by
number with the numbering starting at 0. Otherwise the
<tt>TIFFReadDirectory</tt> and <tt>TIFFWriteDirectory</tt> routines can
be used for sequential access to directories.
For example, to count the number of directories in a file the following
code might be used:
</p>
<p style="margin-left: 40px">
<tt>#include "tiffio.h"<br>
main(int argc, char* argv[])<br>
{<br>
TIFF* tif = TIFFOpen(argv[1], "r");<br>
if (tif) {<br>
int dircount = 0;<br>
do {<br>
dircount++;<br>
} while (TIFFReadDirectory(tif));<br>
printf("%d directories in %s\n", dircount, argv[1]);<br>
TIFFClose(tif);<br>
}<br>
exit(0);<br>
}</tt>
</p>
<p>
Finally, note that there are several routines for querying the
directory status of an open file:
<tt>TIFFCurrentDirectory</tt> returns the index of the current
directory and
<tt>TIFFLastDirectory</tt> returns an indication of whether the
current directory is the last directory in a file.
There is also a routine, <tt>TIFFPrintDirectory</tt>, that can
be called to print a formatted description of the contents of
the current directory; consult the manual page for complete details.
</p>
<hr>
<h2 id="tags">TIFF Tags</h2>
<p>
Image-related information such as the image width and height, number
of samples, orientation, colorimetric information, etc.
are stored in each image
directory in <i>fields</i> or <i>tags</i>.
Tags are identified by a number that is usually a value registered
with the Aldus (now Adobe) Corporation.
Beware however that some vendors write
TIFF images with tags that are unregistered; in this case interpreting
their contents is usually a waste of time.
</p>
<p>
<tt>libtiff</tt> reads the contents of a directory all at once
and converts the on-disk information to an appropriate in-memory
form. While the TIFF specification permits an arbitrary set of
tags to be defined and used in a file, the library only understands
a limited set of tags.
Any unknown tags that are encountered in a file are ignored.
There is a mechanism to extend the set of tags the library handles
without modifying the library itself;
this is described <a href="addingtags.html">elsewhere</a>.
</p>
<p>
<tt>libtiff</tt> provides two interfaces for getting and setting tag
values: <tt>TIFFGetField</tt> and <tt>TIFFSetField</tt>.
These routines use a variable argument list-style interface to pass
parameters of different type through a single function interface.
The <i>get interface</i> takes one or more pointers to memory locations
where the tag values are to be returned and also returns one or
zero according to whether the requested tag is defined in the directory.
The <i>set interface</i> takes the tag values either by-reference or
by-value.
The TIFF specification defines
<i>default values</i> for some tags.
To get the value of a tag, or its default value if it is undefined,
the <tt>TIFFGetFieldDefaulted</tt> interface may be used.
</p>
<p>
The manual pages for the tag get and set routines specifiy the exact data types
and calling conventions required for each tag supported by the library.
</p>
<hr>
<h2 id="compression">TIFF Compression Schemes</h2>
<p>
<tt>libtiff</tt> includes support for a wide variety of
data compression schemes.
In normal operation a compression scheme is automatically used when
the TIFF <tt>Compression</tt> tag is set, either by opening a file
for reading, or by setting the tag when writing.
</p>
<p>
Compression schemes are implemented by software modules termed <i>codecs</i>
that implement decoder and encoder routines that hook into the
core library i/o support.
Codecs other than those bundled with the library can be registered
for use with the <tt>TIFFRegisterCODEC</tt> routine.
This interface can also be used to override the core-library
implementation for a compression scheme.
</p>
<hr>
<h2 id="byteorder">Byte Order</h2>
<p>
The TIFF specification says, and has always said, that
<em>a correct TIFF
reader must handle images in big-endian and little-endian byte order</em>.
<tt>libtiff</tt> conforms in this respect.
Consequently there is no means to force a specific
byte order for the data written to a TIFF image file (data is
written in the native order of the host CPU unless appending to
an existing file, in which case it is written in the byte order
specified in the file).
</p>
<hr>
<h2 id="dataplacement">Data Placement</h2>
<p>
The TIFF specification requires that all information except an
8-byte header can be placed anywhere in a file.
In particular, it is perfectly legitimate for directory information
to be written after the image data itself.
Consequently TIFF is inherently not suitable for passing through a
stream-oriented mechanism such as UNIX pipes.
Software that require that data be organized in a file in a particular
order (e.g. directory information before image data) does not
correctly support TIFF.
<tt>libtiff</tt> provides no mechanism for controlling the placement
of data in a file; image data is typically written before directory
information.
</p>
<hr>
<h2 id="tiffrgbaimage">TIFFRGBAImage Support</h2>
<p>
<tt>libtiff</tt> provides a high-level interface for reading image
data from a TIFF file. This interface handles the details of
data organization and format for a wide variety of TIFF files;
at least the large majority of those files that one would normally
encounter. Image data is, by default, returned as ABGR
pixels packed into 32-bit words (8 bits per sample). Rectangular
rasters can be read or data can be intercepted at an intermediate
level and packed into memory in a format more suitable to the
application.
The library handles all the details of the format of data stored on
disk and, in most cases, if any colorspace conversions are required:
bilevel to RGB, greyscale to RGB, CMYK to RGB, YCbCr to RGB, 16-bit
samples to 8-bit samples, associated/unassociated alpha, etc.
</p>
<p>
There are two ways to read image data using this interface. If
all the data is to be stored in memory and manipulated at once,
then the routine <tt>TIFFReadRGBAImage</tt> can be used:
</p>
<p>
<p style="margin-left: 40px">
<tt>#include "tiffio.h"<br>
main(int argc, char* argv[])<br>
{<br>
TIFF* tif = TIFFOpen(argv[1], "r");<br>
if (tif) {<br>
uint32 w, h;<br>
size_t npixels;<br>
uint32* raster;<br>
<br>
TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &w);<br>
TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &h);<br>
npixels = w * h;<br>
raster = (uint32*) _TIFFmalloc(npixels * sizeof (uint32));<br>
if (raster != NULL) {<br>
if (TIFFReadRGBAImage(tif, w, h, raster, 0)) {<br>
...process raster data...<br>
}<br>
_TIFFfree(raster);<br>
}<br>
TIFFClose(tif);<br>
}<br>
exit(0);<br>
}</tt>
</p>
<p>
Note above that <tt>_TIFFmalloc</tt> is used to allocate memory for
the raster passed to <tt>TIFFReadRGBAImage</tt>; this is important
to insure the ``appropriate type of memory'' is passed on machines
with segmented architectures.
</p>
<p>
Alternatively, <tt>TIFFReadRGBAImage</tt> can be replaced with a
more low-level interface that permits an application to have more
control over this reading procedure. The equivalent to the above
is:
</p>
<p style="margin-left: 40px">
<tt>#include "tiffio.h"<br>
main(int argc, char* argv[])<br>

<p>
However this usage does not take advantage of the more fine-grained
control that's possible. That is, by using this interface it is
possible to:
</p>
<ul>
<li>repeatedly fetch (and manipulate) an image without opening
and closing the file</li>
<li>interpose a method for packing raster pixel data according to
application-specific needs (or write the data at all)</li>
<li>interpose methods that handle TIFF formats that are not already
handled by the core library</li>
</ul>
<p>
The first item means that, for example, image viewers that want to
handle multiple files can cache decoding information in order to
speedup the work required to display a TIFF image.
</p>
<p>
The second item is the main reason for this interface. By interposing
a "put method" (the routine that is called to pack pixel data in
the raster) it is possible share the core logic that understands how
to deal with TIFF while packing the resultant pixels in a format that
is optimized for the application. This alternate format might be very
different than the 8-bit per sample ABGR format the library writes by
default. For example, if the application is going to display the image
on an 8-bit colormap display the put routine might take the data and
convert it on-the-fly to the best colormap indices for display.
</p>
<p>
The last item permits an application to extend the library
without modifying the core code.
By overriding the code provided an application might add support
for some esoteric flavor of TIFF that it needs, or it might
substitute a packing routine that is able to do optimizations
using application/environment-specific information.
</p>
<p>
The TIFF image viewer found in <b>tools/sgigt.c</b> is an example
of an application that makes use of the <tt>TIFFRGBAImage</tt>
support.
</p>
<hr>
<h2 id="scanlines">Scanline-based Image I/O</h2>
<p>
The simplest interface provided by <tt>libtiff</tt> is a
scanline-oriented interface that can be used to read TIFF
images that have their image data organized in strips
(trying to use this interface to read data written in tiles
will produce errors.)
A scanline is a one pixel high row of image data whose width
is the width of the image.
Data is returned packed if the image data is stored with samples
packed together, or as arrays of separate samples if the data
is stored with samples separated.
The major limitation of the scanline-oriented interface, other
than the need to first identify an existing file as having a
suitable organization, is that random access to individual
scanlines can only be provided when data is not stored in a
compressed format, or when the number of rows in a strip
of image data is set to one (<tt>RowsPerStrip</tt> is one).
</p>
<p>
Two routines are provided for scanline-based i/o:
<tt>TIFFReadScanline</tt>
and
<tt>TIFFWriteScanline</tt>.
For example, to read the contents of a file that
is assumed to be organized in strips, the following might be used:
</p>
<p style="margin-left: 40px">
<tt>#include "tiffio.h"<br>
main()<br>
{<br>
TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
if (tif) {<br>
uint32 imagelength;<br>
tdata_t buf;<br>
uint32 row;<br>
<br>
TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &imagelength);<br>
buf = _TIFFmalloc(TIFFScanlineSize(tif));<br>
for (row = 0; row < imagelength; row++)<br>
tiffreadscanline(tif, buf, row);<br>
_tifffree(buf);<br>
tiffclose(tif);<br>
}<br>
}</tt>
</p>
<p>
<tt>TIFFScanlineSize</tt> returns the number of bytes in
a decoded scanline, as returned by <tt>TIFFReadScanline</tt>.
Note however that if the file had been create with samples
written in separate planes, then the above code would only
read data that contained the first sample of each pixel;
to handle either case one might use the following instead:
</p>
<p style="margin-left: 40px">
<tt>#include "tiffio.h"<br>
main()<br>
{<br>
TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
if (tif) {<br>
uint32 imagelength;<br>
tdata_t buf;<br>
uint32 row;<br>
<br>
TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &imagelength);<br>
TIFFGetField(tif, TIFFTAG_PLANARCONFIG, &config);<br>
buf = _TIFFmalloc(TIFFScanlineSize(tif));<br>
if (config == PLANARCONFIG_CONTIG) {<br>
for (row = 0; row < imagelength; row++)<br>
tiffreadscanline(tif, buf, row);<br>
} else if (config == planarconfig_separate) {<br>
uint16 s, nsamples;<br>
<br>
tiffgetfield(tif, tifftag_samplesperpixel, &nsamples);<br>
for (s = 0; s < nsamples; s++)<br>
for (row = 0; row < imagelength; row++)<br>
tiffreadscanline(tif, buf, row, s);<br>
}<br>
_tifffree(buf);<br>
tiffclose(tif);<br>
}<br>
}</tt>
</p>
<p>
Beware however that if the following code were used instead to
read data in the case <tt>PLANARCONFIG_SEPARATE</tt>,...
</p>
<p style="margin-left: 40px">
<tt> for (row = 0; row < imagelength; row++)<br>
for (s = 0; s < nsamples; s++)<br>
tiffreadscanline(tif, buf, row, s);</tt>
</p>
<p>
...then problems would arise if <tt>RowsPerStrip</tt> was not one
because the order in which scanlines are requested would require
random access to data within strips (something that is not supported
by the library when strips are compressed).
</p>
<hr>
<h2 id="strips">Strip-oriented Image I/O</h2>
<p>
The strip-oriented interfaces provided by the library provide
access to entire strips of data. Unlike the scanline-oriented
calls, data can be read or written compressed or uncompressed.
Accessing data at a strip (or tile) level is often desirable
because there are no complications with regard to random access
to data within strips.
</p>
<p>
A simple example of reading an image by strips is:
</p>
<p style="margin-left: 40px">
<tt>#include "tiffio.h"<br>
main()<br>
{<br>
TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
if (tif) {<br>
tdata_t buf;<br>
tstrip_t strip;<br>
<br>
buf = _TIFFmalloc(TIFFStripSize(tif));<br>
for (strip = 0; strip < tiffnumberofstrips(tif); strip++)<br>
tiffreadencodedstrip(tif, strip, buf, (tsize_t) -1);<br>
_tifffree(buf);<br>
tiffclose(tif);<br>
}<br>
}</tt>
</p>
<p>
Notice how a strip size of <tt>-1</tt> is used; <tt>TIFFReadEncodedStrip</tt>
will calculate the appropriate size in this case.
</p>
<p>
The above code reads strips in the order in which the
data is physically stored in the file. If multiple samples
are present and data is stored with <tt>PLANARCONFIG_SEPARATE</tt>
then all the strips of data holding the first sample will be
read, followed by strips for the second sample, etc.
</p>
<p>
Finally, note that the last strip of data in an image may have fewer
rows in it than specified by the <tt>RowsPerStrip</tt> tag. A
reader should not assume that each decoded strip contains a full
set of rows in it.
</p>
<p>
The following is an example of how to read raw strips of data from
a file:
</p>
<p style="margin-left: 40px">
<tt>#include "tiffio.h"<br>
main()<br>
{<br>
TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
if (tif) {<br>
tdata_t buf;<br>
tstrip_t strip;<br>
uint32* bc;<br>
uint32 stripsize;<br>
<br>
TIFFGetField(tif, TIFFTAG_STRIPBYTECOUNTS, &bc);<br>
stripsize = bc[0];<br>
buf = _TIFFmalloc(stripsize);<br>
for (strip = 0; strip < tiffnumberofstrips(tif); strip++) {<br>
if (bc[strip] > stripsize) {<br>
buf = _TIFFrealloc(buf, bc[strip]);<br>
stripsize = bc[strip];<br>
}<br>
TIFFReadRawStrip(tif, strip, buf, bc[strip]);<br>
}<br>
_TIFFfree(buf);<br>
TIFFClose(tif);<br>
}<br>
}</tt>
</p>
<p>
As above the strips are read in the order in which they are
physically stored in the file; this may be different from the
logical ordering expected by an application.
</p>
<hr>
<h2 id="tiles">Tile-oriented Image I/O</h2>
<p>
Tiles of data may be read and written in a manner similar to strips.
With this interface, an image is
broken up into a set of rectangular areas that may have dimensions
less than the image width and height. All the tiles
in an image have the same size, and the tile width and length must each
be a multiple of 16 pixels. Tiles are ordered left-to-right and
top-to-bottom in an image. As for scanlines, samples can be packed
contiguously or separately. When separated, all the tiles for a sample
are colocated in the file. That is, all the tiles for sample 0 appear
before the tiles for sample 1, etc.
</p>
<p>
Tiles and strips may also be extended in a z dimension to form
volumes. Data volumes are organized as "slices". That is, all the
data for a slice is colocated. Volumes whose data is organized in
tiles can also have a tile depth so that data can be organized in
cubes.
</p>
<p>
There are actually two interfaces for tiles.
One interface is similar to scanlines, to read a tiled image,
code of the following sort might be used:
</p>
<p style="margin-left: 40px">
<tt>main()<br>
{<br>
TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
if (tif) {<br>
uint32 imageWidth, imageLength;<br>
uint32 tileWidth, tileLength;<br>
uint32 x, y;<br>
tdata_t buf;<br>
<br>
TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &imageWidth);<br>
TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &imageLength);<br>
TIFFGetField(tif, TIFFTAG_TILEWIDTH, &tileWidth);<br>
TIFFGetField(tif, TIFFTAG_TILELENGTH, &tileLength);<br>
buf = _TIFFmalloc(TIFFTileSize(tif));<br>
for (y = 0; y < imagelength; y += tilelength)<br>
for (x = 0; x < imagewidth; x += tilewidth)<br>
tiffreadtile(tif, buf, x, y, 0);<br>
_tifffree(buf);<br>
tiffclose(tif);<br>
}<br>
}</tt>
</p>
<p>
(once again, we assume samples are packed contiguously.)
</p>
<p>
Alternatively a direct interface to the low-level data is provided
a la strips. Tiles can be read with
<tt>TIFFReadEncodedTile</tt> or <tt>TIFFReadRawTile</tt>,
and written with <tt>TIFFWriteEncodedTile</tt> or
<tt>TIFFWriteRawTile</tt>. For example, to read all the tiles in an image:
</p>
<p style="margin-left: 40px">
<tt>#include "tiffio.h"<br>
main()<br>
{<br>
TIFF* tif = TIFFOpen("myfile.tif", "r");<br>
if (tif) {<br>
tdata_t buf;<br>
ttile_t tile;<br>
<br>
buf = _TIFFmalloc(TIFFTileSize(tif));<br>
for (tile = 0; tile < tiffnumberoftiles(tif); tile++)<br>
tiffreadencodedtile(tif, tile, buf, (tsize_t) -1);<br>
_tifffree(buf);<br>
tiffclose(tif);<br>
}<br>
}</tt>

The libtiff software was written by Sam Leffler while working for
Silicon Graphics.<p>
The LZW algorithm is derived from the compress program (the proper attribution
is included in the source code). The Group 3 fax stuff originated as code
from Jef Poskanzer, but has since been rewritten several times. The latest
version uses an algorithm from Frank Cringle -- consult
<TT>libtiff/mkg3states.c</TT> and <TT>libtiff/tif_fax3.h</TT> for further
information. The JPEG support was written by Tom Lane and is dependent on the
excellent work of Tom Lane and the Independent JPEG Group (IJG) who distribute
their work under friendly licensing similar to this software. Joris Van Damme
implemented the robust Old JPEG decoder (as included in libtiff since version
3.9.0, there was another Old JPEG module in older releases, which was
incomplete and unsuitable for many existing images of that format). JBIG
module was written by Lee Howard and depends on JBIG library from the Markus
Kuhn. Many other people have by now helped with bug fixes and code; a few of
the more persistent contributors have been:

<p>
The <tt>Matteing</tt> and <tt>DataType</tt>
tags have been obsoleted by the 6.0
<tt>ExtraSamples</tt> and <tt>SampleFormat</tt> tags.
Consult the documentation on the
<tt>ExtraSamples</tt> tag and Associated Alpha for elaboration. Note however
that if you use Associated Alpha, you are expected to save data that is
pre-multipled by Alpha. If this means nothing to you, check out
Porter & Duff's paper in the '84 SIGGRAPH proceedings: "Compositing Digital
Images".
</p>
<p>
The <tt>ImageDepth</tt>
tag is a non-standard, but registered tag that specifies
the Z-dimension of volumetric data. The combination of <tt>ImageWidth</tt>,
<tt>ImageLength</tt>, and <tt>ImageDepth</tt>,
defines a 3D volume of pixels that are
further specified by <tt>BitsPerSample</tt> and
<tt>SamplesPerPixel</tt>. The <tt>TileDepth</tt>
tag (also non-standard, but registered) can be used to specified a
subvolume "tiling" of a volume of data.
</p>
<p>
The Colorimetry, and CMYK tags are additions that appear in TIFF 6.0.
Consult the TIFF 6.0 specification included in the <b>doc</b> directory
and <a href="document.html">online</a>.
</p>
<p>
The JPEG-related tag is specified in
<a href="TIFFTechNote2.html">TIFF Technical Note #2</a> which defines
a revised JPEG-in-TIFF scheme (revised over that appendix that was
part of the TIFF 6.0 specification).

Tools Overview</font></h1>
<p>This software distribution comes with a small collection of
programs for converting non-TIFF format images to TIFF and for
manipulating and interrogating the contents of TIFF images. Several
of these tools are useful in their own right. Many of them however
are more intended to serve as programming examples for using the
TIFF library.</p>
<h3>Device-dependent Programs</h3>
There are two device-dependent programs that serve as simple
examples for writing programs to display and save TIFF images.
<table border cellpadding="3">
<tr>
<td valign="top" width="10%">
<tt><a href="man/tiffgt.1.html">tiffgt</a> </tt></td>
<td>Display the contents of one or more TIFF images using OpenGL.
The software makes extensive use of the <tt>TIFFRGBAImage</tt>
facilities described elsewhere.</td>
</tr>
</table>
<h3>Device-independent Programs</h3>
The remaining programs should be device-independent:
<table border cellpadding="3">
<td valign="top" width="10%"><tt><a href="man/fax2ps.1.html">fax2ps</a></tt></td>
<td>Convert a Group 3- or Group 4- compressed TIFF to PostScript
that is significantly more compressed than is generated by
<tt>tiff2ps</tt> (unless <tt>tiff2ps</tt> writes PS Level II)</td>
</tr>
<tr>
<td valign="top" width="10%"><tt><a href="man/fax2tiff.1.html">fax2tiff</a></tt></td>
<td>Convert raw Group 3 or Group 4 facsimile data to TIFF</td>
</tr>
<td valign="top" width="10%"><tt><a href="man/pal2rgb.1.html">pal2rgb</a></tt></td>
<td>Convert a Palette-style image to a full color RGB image by
applying the colormap</td>
</tr>
<tr>
<td valign="top" width="10%"><tt><a href="man/ppm2tiff.1.html">ppm2tiff</a></tt></td>
<td>A quick hack that converts 8-bit PPM format images to TIFF</td>
</tr>
<td valign="top" width="10%"><tt><a href="man/raw2tiff.1.html">raw2tiff</a></tt></td>
<td>Create a TIFF file from raw data</td>
</tr>
<tr>
<td valign="top" width="10%"><tt><a href="man/rgb2ycbcr.1.html">rgb2ycbcr</a></tt></td>
<td>Convert an RGB, grayscale, or bilevel TIFF image to a YCbCr
TIFF image; it's mainly provided for testing</td>
</tr>
<tr>
<td valign="top" width="10%"><tt><a href="man/thumbnail.1.html">thumbnail</a></tt></tt></td>
<td>Copy a bilevel TIFF to one that includes 8-bit greyscale
"thumbnail images" for each page; it is provided as an example of
how one might use the <tt>SubIFD</tt> tag (and the library support
for it)</td>
</tr>
<tr>
<td valign="top" width="10%"><tt><a href="man/tiff2bw.1.html">tiff2bw</a></tt></td>

the directory information, but does check all the data)</td>
</tr>
<tr>
<td valign="top" width="10%"><tt><a href="man/tiffcp.1.html">tiffcp</a></tt></td>
<td>Copy, concatenate, and convert TIFF images (e.g. switching from
Compression=5 to Compression=1)</td>
</tr>
<tr>
<td valign="top" width="10%"><tt><a href="man/tiffcrop.1.html">tiffcrop</a></tt></td>
<td>Provides selection of images from within one or more multi-image
TIFF files, with orthogonal rotation, mirroring, cropping, and
extraction of multiple sections and exporting to one or more files.
It extends the functionality of tiffcp to support additional bit
depths in strips and tiles and enhances the selection capabilities of
tiffsplit. Bilevel images can be inverted and images may be split into
segments to fit on multiple /pages/ (standard paper sizes), plus other
functions described in the tiffcrop man page</td>
</tr>
<tr>
<td valign="top" width="10%"><tt><a href="man/tiffdither.1.html">tiffdither</a></tt></td>

someone that claims they support TIFF)</td>
</tr>
<tr>
<td valign="top" width="10%"><tt><a href="man/tiffinfo.1.html">tiffinfo</a></tt></td>
<td>Display information about one or more TIFF files.</td>

<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
<UL>
<LI>It is now possible to setup the software to build only the
library; configure reconizes this is the intent when the
<B>VERSION</B>, <B>tiff.alpha</B>, and <B>tif_version.c</B>
files are in the local directory (i.e. ``.'')
<LI>configure no longer tries to setup HTML materials
<LI>include file directories needed in building the library are now
specified with a <TT>DIRS_LIBINC</TT> config parameter
<LI>configure no longer checks for alternate compilers if <TT>CC</TT>
is set; if the specified compiler is not found or is not appropriate
the configuration procedure aborts
<LI>the <B>port.h</B> file generated by configure is now used only by
the library and as such as have been moved to the <B>libtiff</B>
directory
<LI>there is beginning support for building DSO's on systems other than IRIX
<LI>configure now verifies the JPEG and zlib directory pathnames by
checking for well-known include files in these directories
<LI>configure no longer creates the <B>dist</B> directory needed only
on SGI machines (for building SGI binary distributions)
<LI>a bug was fixed whereby configure would incorrectly set
<TT>ENVOPTS</TT> when building the software with gcc under AIX
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
<UL>
<LI>two new typedefs were added to <B>tiff.h</TT>: <TT>int8</TT>
and <TT>uint8</TT> for signed and unsigned 8-bit quantities,
respectively; these are currently used only by

making calls though)
<LI><TT>TIFFDefaultTileSize</TT> now rounds tile width and height
up to a multiple of 16 pixels, as required by the TIFF 6.0 specification
<LI>the file <B>version.h</B> is now built by a new <B>mkversion</B>
program; this was done for portability to non-UNIX systems

<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
<UL>
<LI>a <TT>-noninteractive</TT> flag was added to configure to
control whether or not it prints and prompts for configuration information
<LI>various typos and fixes were made in configure for the the
library-only build support (this and other configure fixes from
Richard Mlynarik <A HREF=mailto:mly@adoc.xerox.com><mly@adoc.xerox.com></A>)
<LI>bugs were fixed in the handling of pathnames supplied for external
packages; e.g. <TT>DIR_JPEG</TT>
<LI>the handling of <TT>SETMAKE</TT> is now done properly
<LI>the default prototype function declaration for <TT>pow</TT> was corrected

<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
<UL>
<LI>Acorn RISC O/S support that was accidentally left out of the
left out of the previous distribution is present (from Peter Greenham)
<LI>complaints about unknown and/or unsupported codecs have been
delayed until they are invoked; this permits applications to open
images and look at tags even if the image data is compressed with
an unknown/unsupported compression scheme
<LI>bugs in handling unknown tags have been corrected; applications
that use multiple codecs, each with codec-specific tags, no longer
generate confusing error messages
<LI>a missing pseudo-tag definition in the CCITT G3 codec was fixed
(this problem caused core dumps in the <TT>tiffcp</TT> program)
<LI>pseudo-tags are now treated specially; they are always considered
to be set (i.e. they do not use bits in the <TT>FIELD_*</TT> bit-vectors).
<LI>the use of strip chopping can now be controlled on a per-file basis
through a mode parameter supplied when opening a file (``C'' to
enable strip chopping and ``c'' to disable)
<LI>two bugs were fixed in the writing of opposite-endian byte-order
files
<LI>support was added for three new fax-related tags registered to
SGI: FaxRecvParams, FaxRecvTime, and FaxSubAddress
<LI>the bit order of image data read and written can now be controlled
on a per-file basis through a mode parameter supplied when opening
a file (``B'' to force MSB2LSB bit order, ``L'' for LSB2MSB bit
order, and ``H'' for the bit order of the native CPU)
<LI>the byte order of image and tag data written to newly-created files
can now be controlled on a per-file basis through a mode parameter
supplied when openening a file (``b'' to force Big-Endian byte order
and ``l'' to force Little-Endian byte order)
<LI>the use memory-mapped files for images opened read-only can now
be controlled on a per-file basis through a mode parameter supplied
when opening a file (``M'' to enable use of memory-mapped files
and ``m'' to disable use)
<LI>the use of the <TT>WIN32</TT> define in <B>tiffiop.h</B> has
been replaced by <TT>__WIN32__</TT>
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A>
<UL>
<LI><TT>fax2ps</TT> now does a <TT>save</TT> and <TT>restore</TT>
around each page of PostScript; this fixes a problem with VM
overflow when printing a many-page document on some printers
<LI>a bug in the handling of 3-channel images by <TT>ras2tiff</TT>
was fixed
<LI><TT>tiffcp</TT> has new options to control the byte order of
newly created files: <B>-B</B> for Big-Endian byte order, <B>-L</B>
for Little-Endian byte order; a <B>-M</B> option to disable the
use of memory-mapped files, and a <B>-C</B> option to disable the

<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
<UL>
<LI><B>configure</B> now captures significantly more information
in the <B>config.log</B> file and provides more information when
it is unable to setup a configuration
<LI>support was added for building shared libraries on more systems:
AIX, HPUX, Solaris, and Linux.
<LI>a new configuration parameter <TT>LIBCOPTS</TT> was added for
passing arguments to the C compiler to use when building only
the library; this is part of the enhanced support for building
shared libraries
<LI>include files for optional packages that reside in <B>/usr/include</B>
are now handled correctly
<LI>build trees may now be configured using either relative or absolute
pathnames to the source distribution
<LI>several new configuration parameters were added, mainly for building
shared libraries: <TT>DIST_MAJOR</TT>, <TT>DIST_MINOR</TT>,
<TT>DIST_ALPHA</TT>, and <TT>DSOSUF_VERSION</TT>

the zlib software distribution, <B>the output format has changed and
is incompatible with previous versions of this library</B> (each
strip now includes a header read and written by the zlib library)
<LI>the codec name printed by the TIFFPrintDirectory routine is now
taken from the codec table instead of from a builtin table; this means
that application-defined codecs are handled correctly
<LI>a new symbol was added that contains the library version number;
this can be used to do a compile-time compatibility check of the

PK 粐\( �H�t �t ChangeLognu �[��� 2017-11-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* configure.ac: libtiff 4.0.9 released.
* html/v4.0.9.html: Add HTML file to document changes in libtiff
v4.0.9.
2017-11-17 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_aux.c, tif_getimage.c, tif_read.c: typo fixes in
comments.
2017-11-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* test/Makefile.am: Add some tests for tiff2bw.
2017-11-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* tools/tiff2bw.c (main): Free memory allocated in the tiff2bw
program. This is in response to the report associated with
CVE-2017-16232 but does not solve the extremely high memory usage
with the associated POC file.
2017-10-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* tools/tiff2pdf.c (t2p_sample_realize_palette): Fix possible
arithmetic overflow in bounds checking code and eliminate
comparison between signed and unsigned type.
* tools/fax2tiff.c (_FAX_Client_Data): Pass FAX_Client_Data as the
client data. This client data is not used at all at the moment,
but it makes the most sense. Issue that the value of
client_data.fd was passed where a pointer is expected was reported
via email by Gerald Schade on Sun, 29 Oct 2017.
2017-10-23 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_getimage.c: avoid floating point division by zero in
initCIELabConversion()
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3733
Credit to OSS Fuzz
2017-10-17 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_jpeg.c: add compatibility with libjpeg-turbo 1.5.2 that
honours max_memory_to_use > 0.
Cf https://github.com/libjpeg-turbo/libjpeg-turbo/issues/162
2017-10-10 Even Rouault <even.rouault at spatialys.com>
* nmake.opt: support a DEBUG=1 option, so as to adjust OPTFLAGS and use
/MDd runtime in debug mode.
2017-10-01 Even Rouault <even.rouault at spatialys.com>
* tools/tiffset.c: fix setting a single value for the ExtraSamples tag
(and other tags with variable number of values).
So 'tiffset -s ExtraSamples 1 X'. This only worked
when setting 2 or more values, but not just one.
2017-09-29 Even Rouault <even.rouault at spatialys.com>
* libtiff/libtiff.def: add TIFFReadRGBAStripExt and TIFFReadRGBATileExt
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2735
2017-09-09 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_dirread.c: add NULL check to avoid likely false positive
null-pointer dereference warning by CLang Static Analyzer.
2017-09-07 Even Rouault <even.rouault at spatialys.com>
* libtiff/tiffiop.h, tif_aux.c: redirect SeekOK() macro to a _TIFFSeekoK()
function that checks if the offset is not bigger than INT64_MAX, so as
to avoid a -1 error return code of TIFFSeekFile() to match a required
seek to UINT64_MAX/-1.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2726
Adapted from proposal by Nicolas Ruff.
2017-08-29 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_jpeg.c: accept reading the last strip of a JPEG compressed
file if the codestream height is larger than the truncated height of the
strip. Emit a warning in this situation since this is non compliant.
2017-08-28 Even Rouault <even.rouault at spatialys.com>
* test/Makefile.am: add missing reference to images/quad-lzw-compat.tiff
to fix "make distcheck". Patch by Roger Leigh
2017-08-23 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_dirwrite.c: replace assertion to tag value not fitting
on uint32 when selecting the value of SubIFD tag by runtime check
(in TIFFWriteDirectoryTagSubifd()).
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2728
Reported by team OWL337
2017-08-23 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_dirwrite.c: replace assertion related to not finding the
SubIFD tag by runtime check (in TIFFWriteDirectorySec())
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2727
Reported by team OWL337
2017-07-24 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_luv.c: further reduce memory requirements for temporary
buffer when RowsPerStrip >= image_length in LogLuvInitState() and
LogL16InitState().
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2700
Credit to OSS Fuzz
2017-07-24 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_getimage.c: fix fromskew computation when to-be-skipped
pixel number is not a multiple of the horizontal subsampling, and
also in some other cases. Impact putcontig8bitYCbCr44tile,
putcontig8bitYCbCr42tile, putcontig8bitYCbCr41tile,
putcontig8bitYCbCr21tile and putcontig8bitYCbCr12tile
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2637 (discovered
by Agostino Sarubbo)
and https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2691 (credit
to OSS Fuzz)
2017-07-24 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_getimage.c: gtTileContig() and gtTileSeparate():
properly break from loops on error when stoponerr is set, instead
of going on iterating on row based loop.
2017-07-18 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_luv.c: LogLuvInitState(): avoid excessive memory
allocation when RowsPerStrip tag is missing.
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2683
Credit to OSS-Fuzz
2017-07-15 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_read.c: add protection against excessive memory
allocation attempts in TIFFReadDirEntryArray() on short files.
Effective for mmap'ed case. And non-mmap'ed case, but restricted
to 64bit builds.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2675
2017-07-15 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_read.c: in TIFFFetchStripThing(), only grow the
arrays that hold StripOffsets/StripByteCounts, when they are smaller
than the expected number of striles, up to 1 million striles, and
error out beyond. Can be tweaked by setting the environment variable
LIBTIFF_STRILE_ARRAY_MAX_RESIZE_COUNT.
This partially goes against a change added on 2002-12-17 to accept
those arrays of wrong sizes, but is needed to avoid denial of services.
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2350
Credit to OSS Fuzz
2017-07-15 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_read.c: TIFFFillStrip() / TIFFFillTile().
Complementary fix for http://bugzilla.maptools.org/show_bug.cgi?id=2708
in the isMapped() case, so as to avoid excessive memory allocation
when we need a temporary buffer but the file is truncated.
2017-07-15 Even Rouault <even.rouault at spatialys.com>
* tools/tiff2pdf.c: prevent heap buffer overflow write in "Raw"
mode on PlanarConfig=Contig input images.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2715
Reported by team OWL337
2017-07-11 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_dir.c: avoid potential null pointer dereference in
_TIFFVGetField() on corrupted TIFFTAG_NUMBEROFINKS tag instance.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2713
2017-07-11 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_lzw.c: fix potential out-of-buffer read on 1-byte LZW
strips. Crashing issue only on memory mapped files, where the strip
offset is the last byte of the file, and the file size is a multiple
of one page size on the CPU architecture (typically 4096). Credit
to myself :-)
2017-07-11 Even Rouault <even.rouault at spatialys.com>
* test/tiffcp-lzw-compat.sh, test/images/quad-lzw-compat.tiff: new files
to test old-style LZW decompression
* test/common.sh, Makefile.am, CMakeList.txt: updated with above
2017-07-11 Even Rouault <even.rouault at spatialys.com>
* refresh autoconf/make stuff with what is on Ubuntu 16.04 (minor changes)
2017-07-11 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_lzw.c: fix 4.0.8 regression in the decoding of old-style LZW
compressed files.
2017-07-10 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_pixarlog.c: avoid excessive memory allocation on decoding
when RowsPerStrip tag is not defined (and thus td_rowsperstrip == UINT_MAX)
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2554
Credit to OSS Fuzz
2017-07-04 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_read.c, tiffiop.h: add a _TIFFReadEncodedTileAndAllocBuffer()
and _TIFFReadTileAndAllocBuffer() variants of TIFFReadEncodedTile() and
TIFFReadTile() that allocates the decoded buffer only after a first
successful TIFFFillTile(). This avoids excessive memory allocation
on corrupted files.
* libtiff/tif_getimage.c: use _TIFFReadTileAndAllocBuffer().
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2470
Credit to OSS Fuzz.
2017-07-04 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_error.c, tif_warning.c: correctly use va_list when both
an old-style and new-style warning/error handlers are installed.
Patch by Paavo Helde (sent on the mailing list)
2017-07-02 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_read.c: TIFFStartTile(): set tif_rawcc to
tif_rawdataloaded when it is set. Similarly to TIFFStartStrip().
This issue was revealed by the change of 2017-06-30 in TIFFFileTile(),
limiting the number of bytes read. But it could probably have been hit
too in CHUNKY_STRIP_READ_SUPPORT mode previously ?
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2454
Credit to OSS Fuzz
2017-06-30 Even Rouault <even.rouault at spatialys.com>
* man: update documentation regarding SubIFD tag and
TIFFSetSubDirectory() data type.
Patch by Eric Piel
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2671
2017-06-30 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_dirwrite.c: in TIFFWriteDirectoryTagCheckedXXXX()
functions associated with LONG8/SLONG8 data type, replace assertion that
the file is BigTIFF, by a non-fatal error.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2712
Reported by team OWL337
2017-06-30 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_read.c, tiffiop.h: add a _TIFFReadEncodedStripAndAllocBuffer()
function, variant of TIFFReadEncodedStrip() that allocates the
decoded buffer only after a first successful TIFFFillStrip(). This avoids
excessive memory allocation on corrupted files.
* libtiff/tif_getimage.c: use _TIFFReadEncodedStripAndAllocBuffer().
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2708 and
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2433 .
Credit to OSS Fuzz
2017-06-30 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_read.c: TIFFFillTile(): add limitation to the number
of bytes read in case td_stripbytecount[strip] is bigger than
reasonable, so as to avoid excessive memory allocation (similarly to
what was done for TIFFFileStrip() on 2017-05-10)
2017-06-29 Even Rouault <even.rouault at spatialys.com>
* libtiff/tiffiop.h, libtiff/tif_jpeg.c, libtiff/tif_jpeg_12.c,
libtiff/tif_read.c: make TIFFReadScanline() works in
CHUNKY_STRIP_READ_SUPPORT mode with JPEG stream with multiple scans.
Also make configurable through a LIBTIFF_JPEG_MAX_ALLOWED_SCAN_NUMBER
environment variable the maximum number of scans allowed. Defaults to
100.
2017-06-27 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_dirread.c: in TIFFReadDirEntryFloat(), check that a
double value can fit in a float before casting. Patch by Nicolas RUFF
2017-06-26 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_jbig.c: fix memory leak in error code path of JBIGDecode()
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2706
Reported by team OWL337
2017-06-24 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_jpeg.c: error out at decoding time if anticipated libjpeg
memory allocation is above 100 MB. libjpeg in case of multiple scans,
which is allowed even in baseline JPEG, if components are spread over several
scans and not interleavedin a single one, needs to allocate memory (or
backing store) for the whole strip/tile.
See http://www.libjpeg-turbo.org/pmwiki/uploads/About/TwoIssueswiththeJPEGStandard.pdf
This limitation may be overriden by setting the
LIBTIFF_ALLOW_LARGE_LIBJPEG_MEM_ALLOC environment variable, or recompiling
libtiff with a custom value of TIFF_LIBJPEG_LARGEST_MEM_ALLOC macro.
2017-06-24 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_jpeg.c: add anti-denial of service measure to avoid excessive
CPU consumption on progressive JPEGs with a huge number of scans.
See http://www.libjpeg-turbo.org/pmwiki/uploads/About/TwoIssueswiththeJPEGStandard.pdf
Note: only affects libtiff since 2014-12-29 where support of non-baseline JPEG
was added.
2017-06-18 Even Rouault <even.rouault at spatialys.com>
* libtiff/tiffiop.h: add TIFF_NOSANITIZE_UNSIGNED_INT_OVERFLOW macro to
disable CLang warnings raised by -fsanitize=undefined,unsigned-integer-overflow
* libtiff/tif_predict.c: decorate legitimate functions where unsigned int
overflow occur with TIFF_NOSANITIZE_UNSIGNED_INT_OVERFLOW
* libtiff/tif_dirread.c: avoid unsigned int overflow in EstimateStripByteCounts()
and BYTECOUNTLOOKSBAD when file is too short.
* libtiff/tif_jpeg.c: avoid (harmless) unsigned int overflow on tiled images.
* libtiff/tif_fax3.c: avoid unsigned int overflow in Fax3Encode2DRow(). Could
potentially be a bug with huge rows.
* libtiff/tif_getimage.c: avoid many (harmless) unsigned int overflows.
2017-06-12 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_dirread.c: TIFFFetchStripThing(): limit the number of items
read in StripOffsets/StripByteCounts tags to the number of strips to avoid
excessive memory allocation.
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2215
Credit to OSS Fuzz
2017-06-12 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_dirread.c: fix regression of libtiff 4.0.8 in
ChopUpSingleUncompressedStrip() regarding update of newly single-strip
uncompressed files whose bytecount is 0. Before the change of 2016-12-03,
the condition bytecount==0 used to trigger an early exit/disabling of
strip chop. Re-introduce that in update mode. Otherwise this cause
later incorrect setting for the value of StripByCounts/StripOffsets.
( https://trac.osgeo.org/gdal/ticket/6924 )
2017-06-10 Even Rouault <even.rouault at spatialys.com>
* .appveyor.yml, .travis.yml, build/travis-ci: apply patches
0001-ci-Travis-script-improvements.patch and
0002-ci-Invoke-helper-script-via-shell.patch by Roger Leigh
(sent to mailing list)
2017-06-08 Even Rouault <even.rouault at spatialys.com>
* .travis.yml, build/travis-ci: new files from
0001-ci-Add-Travis-support-for-Linux-builds-with-Autoconf.patch by
Roger Leigh (sent to mailing list on 2017-06-08)
This patch adds support for the Travis-CI service.
* .appveyor.yml: new file from
0002-ci-Add-AppVeyor-support.patch by Roger Leigh (sent to mailing
list on 2017-06-08)
This patch adds a .appveyor.yml file to the top-level. This allows
one to opt in to having a branch built on Windows with Cygwin,
MinGW and MSVC automatically when a branch is pushed to GitHub,
GitLab, BitBucket or any other supported git hosting service.
* CMakeLists.txt, test/CMakeLists.txt, test/TiffTestCommon.cmake: apply
patch 0001-cmake-Improve-Cygwin-and-MingGW-test-support.patch from Roger
Leigh (sent to mailing list on 2017-06-08)
This patch makes the CMake build system support running the tests
with MinGW or Cygwin.
2017-06-08 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_swab.c: if DISABLE_CHECK_TIFFSWABMACROS is defined, do not do
the #ifdef TIFFSwabXXX checks. Make it easier for GDAL to rename the symbols
of its internal libtiff copy.
2017-06-01 Even Rouault <even.rouault at spatialys.com>
* libtiff/tif_dirinfo.c, tif_dirread.c: add _TIFFCheckFieldIsValidForCodec(),
and use it in TIFFReadDirectory() so as to ignore fields whose tag is a
codec-specified tag but this codec is not enabled. This avoids TIFFGetField()
to behave differently depending on whether the codec is enabled or not, and
thus can avoid stack based buffer overflows in a number of TIFF utilities
such as tiffsplit, tiffcmp, thumbnail, etc.

* libtiff/tif_dirread.c: modify ChopUpSingleUncompressedStrip() to
instanciate compute ntrips as TIFFhowmany_32(td->td_imagelength, rowsperstrip),

* libtiff/tif_dir.c: discard values of SMinSampleValue and
SMaxSampleValue when they have been read and the value of
SamplesPerPixel is changed afterwards (like when reading a
OJPEG compressed image with a missing SamplesPerPixel tag,
and whose photometric is RGB or YCbCr, forcing SamplesPerPixel
being 3). Otherwise when rewriting the directory (for example
with tiffset, we will expect 3 values whereas the array had been
allocated with just one), thus causing a out of bound read access.

* CMakeLists.txt, libtiff/test/Makefile.am: Applied patches by
Roger Leigh (via tiff mailing list on 2015-08-31.
CMake reads all version information directly from configure.ac to
avoid duplication of values. This basically greps over the file
for the LIBTIFF_* variables, then translates them to the form
needed for cmake. This includes the release version and libtool
shared library version information.
Make shared/static library building configurable. Currently it
always builds shared libraries, with static libs having a _static
suffix (copying zlib, but it means it's got a non-standard name).
CMake has a -DBUILD_SHARED_LIBS=ON|OFF option to select one or the
other, which is now used instead. There's now a single "tiff"
target to build either shared or static as required, and all the
tests and tools are linked with this. Note: the Windows tests fail
when linked with a static libtiff (says: libtiff.dll not found).
Not really a regression since this was not tested up to this
point, and it's likely the unit tests haven't (ever?) been run on
Windows with a static libtiff, so there's some additional
portability issue here to address. Works fine on UNIX systems,
and fine on Windows with the default to build a DLL.
Add a missing file which wasn't being distributed, causing unit
tests to fail. Note that "find . -name '*.cmake'" lists all the
CMake files which need distributing in addition to all the
CMakeLists.txt files (which now are distributed).

* libtiff/tif_config.vc.h: Make adjustments to match the new

needs to be tested.
* configure.ac: For 64-bit MinGW, fix SSIZE_FORMAT formatting
specifier. 64-bit MinGW supports 'long long' but support for
'lld' is not assured by the run-time DLLs and so GCC warns.
Add TIFF_SIZE_T and TIFF_SIZE_FORMAT to provide a type definition
and printf format specifier to deal with printing values of
'size_t' type. In particular, this was necessary for WIN64.
Added a configure test for if the system headers provide 'optarg'
(normal case) and block out the many explicit 'extern' statements
in the utilities. This was found to be necessary under Windows
when getopt is in a DLL and the symbols are already imported with
dllimport via standard header files.
* test/raw_decode.c (XMD_H): Avoid conflicting typedefs for INT32
and boolean in MinGW build due to including jpeglib.h.
* test/rewrite_tag.c (main): Fix problem with location of variable
declaration.

* tools/tiffcp.c: fix crash when converting YCbCr JPEG-compressed to none.
Based on patch by Tomasz Buchert (http://bugzilla.maptools.org/show_bug.cgi?id=2480)
Description: fix for Debian bug #741451
tiffcp crashes when converting JPEG-encoded TIFF to a different
encoding (like none or lzw). For example this will probably fail:
tiffcp -c none jpeg_encoded_file.tif output.tif
The reason is that when the input file contains JPEG data,
the tiffcp code forces conversion to RGB space. However,
the output normally inherits YCbCr subsampling parameters
from the input, which leads to a smaller working buffer
than necessary. The buffer is subsequently overrun inside
cpStripToTile() (called from writeBufferToContigTiles).
Note that the resulting TIFF file would be scrambled even
if tiffcp wouldn't crash, since the output file would contain
RGB data intepreted as subsampled YCbCr values.
This patch fixes the problem by forcing RGB space on the output
TIF if the input is JPEG-encoded and output is *not* JPEG-encoded.

2013-01-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* tools/tiff2ps.c:Fix bug in auto rotate option code. Once a
rotation angle was set by the auto rotate check, it was retained
for all pages that followed instead ofa being retested for each
page. Patch by Richard Nolde.
2013-01-18 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_write.c: tmsize_t related casting warning fixed for
64bit linux.

http://bugzilla.maptools.org/show_bug.cgi?id=2427
2012-12-20 Tom Lane <tgl@sss.pgh.pa.us>
* test/raw_decode.c: Relax raw_decode's pixel-value checks so that
it will pass with more versions of libjpeg. (There are at least
three in active use now, and JPEG_LIB_VERSION doesn't tell us
enough to uniquely identify expected results.)
2012-12-12 Tom Lane <tgl@sss.pgh.pa.us>
* libtiff/tif_print.c: Fix TIFFPrintDirectory's handling of
field_passcount fields: it had the TIFF_VARIABLE and
TIFF_VARIABLE2 cases backwards.
2012-12-10 Tom Lane <tgl@sss.pgh.pa.us>
* tools/ppm2tiff.c: Improve previous patch for CVE-2012-4564:
check the linebytes calculation too, get the max() calculation
straight, avoid redundant error messages, check for malloc
failure.
2012-12-10 Tom Lane <tgl@sss.pgh.pa.us>
* libtiff/tif_pixarlog.c: Improve previous patch for CVE-2012-4447
(to enlarge tbuf for possible partial stride at end) so that
overflow in the integer addition is detected. Per gripe from
Huzaifa Sidhpurwala.
2012-12-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* tools/tiffset.c: tiffset now supports a -u option to unset a
tag. Patch by Zach Baker. See
http://bugzilla.maptools.org/show_bug.cgi?id=2419
2012-11-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* automake: Update Automake to 1.12.5 release.
* libtiff/tif_{unix,vms,win32}.c (_TIFFmalloc): ANSI C does not
require malloc() to return NULL pointer if requested allocation
size is zero. Assure that _TIFFmalloc does.
2012-11-01 Frank Warmerdam <warmerdam@pobox.com>
* tools/ppm2tiff.c: avoid zero size buffer vulnerability.
CVE-2012-4564 - Thanks to Huzaifa Sidhpurwala of the
Red Hat Security Response team for the fix.
2012-10-18 Frank Warmerdam <warmerdam@google.com>

* Makefile.in: Update to Automake 1.12.3
* libtiff{tiff.h, tif_print.c, tif_dirinfo.c, tif_dirread.c}: Add
some TIFF/FX support in libtiff. Add the tag definitions to
tiff.h. Add the related TIFF field definitions to tif_dirinfo.c,
and also fixes an error in a comment. Adds the photometric values
to tif_print.c, and fixes a bug. These changes are by Steve
Underwood.
2012-08-13 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_write.c: Fix bug rewriting image tiles in a
compressed file: http://trac.osgeo.org/gdal/ticket/4771
2012-08-02 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_dirread.c: report error in case of mismatch value
counts for tags (ie. DotRange).
2012-07-26 Tom Lane <tgl@sss.pgh.pa.us>
* libtiff/{tiffio.h, tif_dirinfo.c, libtiff.def}: Add six new
functions TIFFFieldTag(), TIFFFieldName(), TIFFFieldDataType(),
TIFFFieldPassCount(), TIFFFieldReadCount(), TIFFFieldWriteCount()
as external accessors for the opaque type TIFFField.
* tools/tiffset.c: Make tiffset use the above functions instead of
relying on library private headers.
2012-07-19 Tom Lane <tgl@sss.pgh.pa.us>
* tools/tiff2pdf.c: Fix two places where t2p_error didn't get set
after a malloc failure. No crash risk AFAICS, but the program
might not report exit code 1 as desired. h/t mancha@mac.hush.com
2012-07-18 Tom Lane <tgl@sss.pgh.pa.us>
* tools/tiff2pdf.c: Fail when TIFFSetDirectory() fails. This
prevents core dumps or perhaps even arbitrary code execution when
processing a corrupt input file (CVE-2012-3401).
2012-07-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* test/raw_decode.c (main): Test fixes to work with IJG JPEG 7+.
IJG JPEG 7+ uses a different upsampling algorithm which produces
different numeric results.
* libtiff/tif_jpeg.c (JPEGPreDecode): Patch from Even Rouault to
work with IJG JPEG 7+.
2012-07-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* test/raw_decode.c: Add changes so that test can run with build
directory outside of source directory.
2012-07-02 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_jpeg.c: Fix handling when writing RGBA jpeg compressed
imagery (http://trac.osgeo.org/gdal/ticket/4732)
2012-06-20 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_fax3.c: fix memory initialization of runs, only
partly done.

warnings with clang.
2012-06-15 Tom Lane <tgl@sss.pgh.pa.us>
* tools/tiff2pdf.c: Defend against integer overflows while
calculating required buffer sizes (CVE-2012-2113).
2012-06-12 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_print.c: Be careful about printing corrupt inknames.
* libtiff/tif_fax3.c: Ensure runs array is initialized to zeros.
2012-06-07 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_print.c: avoid pretty printing other fields when
we don't have the proper amount and type of data or if the field
is actually autodefined.
2012-06-05 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_tile.c, libtiff/tif_strip.c: Ensure that illegal
ycbcrsubsampling values result in a runtime error, not just an
assertion.
* tests/custom_dir.c: Add testing of EXIF and custom directory
reading and writing.
* libtiff/tif_dir.c, libtiff/tiffio.h: Add TIFFCreateCustomDirectory()
and TIFFCreateEXIFDirectory() functions.
* libtiff/tif_dir.c, tif_print.c : Remove FIELD_CUSTOM handling for
PAGENUMBER, HALFTONEHINTS, and YCBCRSUBSAMPLING. Implement DOTRANGE
differently. This is to avoid using special TIFFGetField/TIFFSetField
rules for these fields in non-image directories (like EXIF).
2012-06-04 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_jpeg.c: Remove code for fixing up h_sampling and v_sampling
in JPEGPreDecode(). If a fixup will be done it needs to be done sooner
in JPEGFixupTagsSubsampling() or else buffer sized may be wrong.
2012-06-01 Frank Warmerdam <warmerdam@google.com>
* tools/tiffinfo.c: Do not try to read image data in EXIF directories.
* libtiff/tif_getimage.c: added support for _SEPARATED CMYK images.
http://bugzilla.maptools.org/show_bug.cgi?id=2379
* libtiff/tif_unix.c: use strerror() to return a more specific error message
on failed open.
http://bugzilla.maptools.org/show_bug.cgi?id=2341
* libtiff/tif_jpeg.c: Fix JPEGDecodeRaw() bugs.
http://bugzilla.maptools.org/show_bug.cgi?id=2386
* tests/decode_raw.c, tests/images/quad-tile.jpg.tiff: add limited support
for testing jpeg in tiff image decoding including the "raw" decode interface.
2012-05-31 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_jpeg.c: avoid overrunning the end of the output buffer in
JPEGDecodeRaw() - mostly likely to occur when there is confusion about
sampling values.
* libtiff/tif_read.c: Make sure tif_rawdatasize is cleared when tif_rawdata is freed.
* libtiff/tif_getimage.c: Add support for greyscale+alpha c/o Jérémie Laval.
http://bugzilla.maptools.org/show_bug.cgi?id=2398
2012-05-29 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_dir.c: avoid using specific set/get logic to process fields in custom directories,
like EXIF directories. This fixes problems like a tag "320" existing in a custom directory getting
processed as if it were a colormap when it isn't really. Damn the wide variety of argument formulations
to get/set functions for different tags!
* libtiff/tif_dir.c: Ensure that we keep track of when tif_rawdata
is a pointer into an mmap()ed file via TIFF_BUFFERMMAP flag.
2012-05-24 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_pixarlog.c: Allocate working buffer one word larger since we "forward
accumulate" and overwrite the end by one word in at least some cases.
2012-05-23 Frank Warmerdam <warmerdam@google.com>
* libtiff/tif_pixarlog.c: avoid accessing out of the lookup arrays for out of range inputs.
* tools/tiffinfo.c: initialize h=0 to avoid undefined variable for degenerate files.
* libtiff/tif_ojpeg.c: if OJPEGWriteHeader() fails once do not bother trying again on
the same image.
* libtiff/tif_ojpeg.c: make things more resilient in the face of files without
stripbytecounts or stripoffsets or where loading these fails.
* libtiff/tif_print.c: be careful about whether min/max values are singular
or one per sample.
* libtiff/tif_print.c: Avoid confusion about count size when printing custom fields.
May affect things like ISOSpeedRatings.
* libtiff/tif_dir.c: avoid one byte past end of ink names reading
in some cases.
2012-05-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* man/TIFFGetField.3tiff: Correct the 'count' field type in the
example for how to retreive the value of unsupported tags.
2012-03-30 Frank Warmerdam <warmerdam@google.com>
* tif_getimage.c: Fix size overflow (zdi-can-1221,CVE-2012-1173)
care of Tom Lane @ Red Hat.
2012-02-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff 4.0.1 released.
* Update automake used to 1.11.3.
* libtiff/tiffio.h: Use double-underbar syntax in GCC printf
attribute specification to lessen the risk of accidental macro
substitution. Patch from Vincent Torri.
2012-01-31 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_dir.c, libtiff/tif_dirread.c: Extra caution around
assumption tag fetching is always successful.
* libtiff/tif_jpeg.c: Extra caution for case where sp is NULL.
2012-01-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* configure.ac: Add support for using library symbol versioning on
ELF systems with the GNU linker. Support is enabled via
--enable-ld-version-script. Disabled by default for now until
there is a decision for how to deploy a libtiff with versioned
symbols after libtiff 4.0.0 was already released.
2011-12-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff/tif_win32.c: Eliminate some minor 64-bit warnings in
tif_win32.c. Patch by Edward Lam.
* configure.ac: Add libtiff private dependency on -llzma for
pkg-config. Patch by Mark Brand.
Updated Automake to 1.11.2.
2011-12-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff 4.0.0 released.
2011-12-08 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_dirread.c, libtiff/tif_read.c: more cautious checking
of _TIFFFillStriles() results (#gdal 4372)
2011-12-07 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_dirread.c: fixes to deal with invalid files where
_TIFFFillStriles() fails, and we try to chop up strips (gdal #4372)
* libtiff/tif_dirread.c: fix error reporting when there is no
tag information struct and name (gdal #4373)
2011-10-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* Update GNU libtool to 2.4.2.
* tools/tiffsplit.c (tiffcp): TIFFGetField count field should be
uint32 type for TIFFTAG_JPEGTABLES. Patch by Christophe
Deroulers.
2011-06-21 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/libtiff.def: Restore TIFFMergeFieldInfo.
2011-05-31 Jim Meyering <meyering@redhat.com>
* libtiff/tif_dirread.c (TIFFFetchStripThing): Free "data" also
upon failure to allocate "resizeddata".
* tools/tiff2ps.c (PSDataBW): Zero buffer *after* checking for
allocation failure, not before.
* libtiff/tif_ojpeg.c: plug leaks on OJPEG read failure path
* tools/rgb2ycbcr.c (cvtRaster): unchecked malloc
* libtiff/tif_jpeg.c, tools/tiff2pdf.c, tools/tiff2ps.c: mark
NULL-deref and possible overflow
* tools/tiff2pdf.c: remove decl+set of set-but-not-used local, "written"
* libtiff/tif_jpeg.c (JPEGInitializeLibJPEG): Remove declaration
and set of otherwise unused local, data_is_empty.
* libtiff/tif_jpeg.c (JPEGDecodeRaw) [JPEG_LIB_MK1_OR_12BIT]:
Diagnose out-of-memory failure and return 0 rather than
dereferencing NULL.
2011-05-24 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_dirread.c: produce special error message for zero tag
directories instead of error out on the malloc(0) failure.
2011-05-16 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_dirinfo.c: Restore TIFFMergeFieldInfo() and
related declarations as they are in active use by libraries
such as libgeotiff, and work just fine. (#2315)
2011-04-20 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_dirinfo.c,tiffio.h: Remove the obsolete
TIFFMergeFieldInfo/TIFFFindFieldInfo/TIFFFindFieldInfoByName API.
http://bugzilla.maptools.org/show_bug.cgi?id=2315
* libtiff/libtiff.def: add some missing (64bit) APIs.
http://bugzilla.maptools.org/show_bug.cgi?id=2316
2011-04-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff 4.0.0beta7 released.
2011-04-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* configure.ac: Should use AC_CANONICAL_HOST since host specifies
the run-time target whereas target is used to specify the final
output target if the package is a build tool (like a compiler),
which libtiff is not. Resolves libtiff bug 2307 "Use
AC_CANONICAL_HOST macro".
2011-04-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* configure.ac: Support configuring TIFF_INT64_FORMAT and
TIFF_UINT64_FORMAT appropriately for MinGW32.
* tools/tiffdump.c (ReadDirectory): MinGW32 needs to use WIN32
printf conventions for 64-bit types because it uses the WIN32 CRT.
* libtiff/{tif_dumpmode.c,tif_luv.c,tif_lzw.c,tif_print.c,
tif_read.c,tif_strip.c,tif_thunder.c}: MinGW32 needs to use WIN32
printf conventions for 64-bit types because it uses the WIN32 CRT.
* tools/tiff2pdf.c (t2p_write_pdf_string): Fix printf syntax not
understood by WIN32 CRT.
* libtiff/tif_ojpeg.c: Fixes to compile with MinGW32 GCC.
* tools/fax2ps.c (main): Use tmpfile() rather than mkstemp() since
it is much more portable. Tmpfile is included in ISO/IEC
9899:1990 and the WIN32 CRT.
2011-03-26 Frank Warmerdam <warmerdam@pobox.com>
* tools/tiffset.c: add -d and -sd switches to allow operation on
a particular directory, not just the first (jef).
2011-03-21 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_thunder.c: Correct potential buffer overflow with
thunder encoded files with wrong bitspersample set. The libtiff
development team would like to thank Marin Barbella and TippingPoint's
Zero Day Initiative for reporting this vulnerability (ZDI-CAN-1004,
CVE-2011-1167).
http://bugzilla.maptools.org/show_bug.cgi?id=2300
2011-03-10 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_fax3.h: Fix to last change allowing zero length
runs at the start of a scanline - needed for legal cases.
2011-03-02 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_fax3.h: Protect against a fax VL(n) codeword commanding
a move left. Without this, a malicious input file can generate an
indefinitely large series of runs without a0 ever reaching the right
margin, thus overrunning our buffer of run lengths. Per CVE-2011-0192.
This is a modified version of a patch proposed by Drew Yao of Apple
Product Security. It adds an unexpected() report, and disallows the
equality case, since emitting a run without increasing a0 still allows
buffer overrun.
2011-02-23 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_jpeg.c: avoid divide by zero in degenerate case (#2296)
* tools/tiff2rgba.c: close source file on error to make leak
detection easier.
* libtiff/tif_getimage.c: avoid leaks if TIFFRGBAImageBegin() fails.
http://bugzilla.maptools.org/show_bug.cgi?id=2295
2011-02-22 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_lzma.c: Maintain tif_rawcc/tif_rawcp (CHUNKY_STRING_READ
_SUPPORT)
2011-02-18 Frank Warmerdam <warmerdam@pobox.com>
* configure.ac, configure: Added support for --enable-chunky-strip-read
configure option to enable the experimental feature from a couple
months ago for reading big strips in chunks.
* configure.ac, tif_read.c, tif_readdir.c, tif_dir.h, tiffiop.h,
tif_write.c, tif_print.c, tif_jpeg.c, tif_dirwrite.c, tif_write.c:
Implement optional support for deferring the load of strip/tile
offset and size tags for optimized scanning of directories. Enabled
with the --enable-defer-strile-load configure option (DEFER_STRILE_LOAD
#define in tif_config.h).
2011-02-11 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_print.c: remove unused variable.
2011-02-09 Frank Warmerdam <warmerdam@pobox.com>

2011-01-24 Olivier Paquet <olivier.paquet@gmail.com>
* libtiff/{tif_dir.{h,c}, tif_dirinfo.c, tif_dirread.c, tif_dirwrite.c,
tif_print.c, tiff.h, tiffiop.h} : Added support for
TIFFTAG_SMINSAMPLEVALUE and TIFFTAG_SMAXSAMPLEVALUE to have different
values for each sample. Presents the min/max of all samples by default for
compatibility. TIFFSetField/TIFFGetField can be made to handle those tags
as arrays by changing the new TIFFTAG_PERSAMPLE pseudo tag.
http://www.asmail.be/msg0055458208.html
2011-01-06 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_pixarlog.c: Note that tif_rawcc/tif_rawcp are not
maintained.
* libtiff/tif_zip.c: Maintain tif_rawcc/tif_rawcp when decoding
for CHUNKY_STRIP_READ_SUPPORT.
* libtiff/tif_jpeg.c: ensure that rawcc and rawcp are maintained
during JPEGPreDecode and JPEGDecode calls.
* libtiff/tif_read.c: larger read ahead for CHUNKY_STRIP_READ_SUPPORT,
as compression formats like JPEG keep 16 lines interleaved in a sense
and might need to touch quite a bit of data.
http://trac.osgeo.org/gdal/ticket/3894
2011-01-03 Lee Howard <faxguy@howardsilvan.com>
* libtiff/tif_jpeg.c: Fix regressions with 2 and 3 band images

t2p_write_pdf_trailer(), thanks to Dmitry V. Levin.
2010-07-07 Andrey Kiselev <dron@ak4719.spb.edu>
* libtiff/tif_dirread.c: Really reset the tag count in CheckDirCount()
to expected value as the warning message suggests. As per bug
http://bugzilla.maptools.org/show_bug.cgi?id=1963
2010-07-06 Andrey Kiselev <dron@ak4719.spb.edu>
* tools/tiffset.c: Properly handle TIFFTAG_PAGENUMBER,
TIFFTAG_HALFTONEHINTS, TIFFTAG_YCBCRSUBSAMPLING, TIFFTAG_DOTRANGE
which should be set by value.
* libtiff/tif_dirinfo.c: Don't use assertions in _TIFFFieldWithTag()
and _TIFFFieldWithName() if the tag is not found in the tag table.
This should be normal situation and returned NULL value should be
properly handled by the caller.
2010-07-02 Andrey Kiselev <dron@ak4719.spb.edu>
* libtiff/tif_getimage.c: Avoid wrong math du to the signed/unsigned
integer type conversions. As per bug

WhitePoint tag as per bug
http://bugzilla.maptools.org/show_bug.cgi?id=2042
* libtiff/tif_getimage.c: Check the number of samples per pixel when
working with YCbCr image in PickContigCase(). As per bug
http://bugzilla.maptools.org/show_bug.cgi?id=2216
* libtiff/tif_dir.c: Set the bogus post-decoding hook when processing
TIFFTAG_BITSPERSAMPLE in _TIFFVSetField() for the case of 8 bit when
we don't need any post-processing. That helps to reset the hook if we
previously set this field to some other value and the hook was
initialized accordingly. As per bug
http://bugzilla.maptools.org/show_bug.cgi?id=2035
2010-07-01 Andrey Kiselev <dron@ak4719.spb.edu>

rename them into _TIFFMultiply32() and _TIFFMultiply64() respectively.
2010-06-30 Andrey Kiselev <dron@ak4719.spb.edu>
* tools/tiff2pdf.c: Better generation of ID field in
t2p_write_pdf_trailer(). Get rid of GCC aliasing warnings.
* tools/tiff2pdf.c: Fixed computation of the tile buffer size when
converting JPEG encoded tiles.
* tools/tiff2pdf.c: Better handling of string fields, use static
string buffers instead of dynamically allocated, use strncpy() instead
of strcpy(), control the string lengths.
2010-06-25 Andrey Kiselev <dron@ak4719.spb.edu>
* tools/tiffcp.c: Initialize buffer arrays with zero to avoid
referencing to uninitialized memory in some cases (e.g. when tile size
set bigger than the image size).
2010-06-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* tools/tiffcrop.c: Patch from Richard Nolde. Reject YCbCr
subsampled data since tiffcrop currently doesn't support it. Fix
JPEG support.
2010-06-13 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_dirinfo.c: Fix invocation of tag compare function (#2201)
* tools/tiff2pdf.c: Fix assorted bugs in tiff2pdf: missing "return"
in t2p_read_tiff_size() causes t2p->tiff_datasize to be set entirely
wrong for COMPRESSION_JPEG case, resulting in memory stomp if actual
size is larger. Also, there are a bunch of places that try to
memset() a malloc'd buffer before checking for malloc failure, which
would result in core dump if there actually were a failure. (#2211)
2010-06-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff/tiffiop.h (TIFFSafeMultiply): Need more castings to
avoid compiler warnings if parameter types are not sign
consistent.
* libtiff 4.0.0alpha6 released.
* tools/tiffcrop.c: Applied patch from Richard Nolde: Corrected
European page size dimensions. Added an option to allow the user
to specify a custom page size on the command line. Fix the case
where a page size specified with a fractional part was being
coerced to an integer by retyping the variables that define the
paper size.
* html/index.html: Update for the 3.9.3 release.
* tools/tiffcp.c (tiffcp): Applied Tom Lane's patch to reject
YCbCr subsampled data since tiffcp currently doesn't support it.
http://bugzilla.maptools.org/show_bug.cgi?id=2097
* Update libtool to version 2.2.10.
2010-06-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff/tiffiop.h (TIFFSafeMultiply): Work properly if
multiplier is zero.
2010-06-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff/tif_fax3.c (Fax3SetupState): Yesterday's fix for
CVE-2010-1411 was not complete.
* libtiff/tiffiop.h (TIFFSafeMultiply): New macro to safely
multiply two integers. Returns zero if there is an integer
overflow.
* tools/tiffcp.c (main): tiffcp should not leak memory if an error
is reported when reading the input file.
2010-06-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* Update libtool to version 2.2.8.
* libtiff/tif_fax3.c (Fax3SetupState): Avoid under-allocation of
buffer due to integer overflow in TIFFroundup() and several other
potential overflows. In conjunction with the fix to TIFFhowmany(),
fixes CVE-2010-1411.
* libtiff/tiffiop.h (TIFFhowmany): Return zero if parameters would
result in an integer overflow. This causes TIFFroundup() to also
return zero if there would be an integer overflow.
* contrib: Add an emacs formatting mode footer to all source files
so that emacs can be effectively used.
2010-06-03 Oliver Chen Feng <scip8183@gmail.com>
* libtiff/tools/tiffcp.c: add a new option -x to force merged tiff
file PAGENUMBER value in sequence for users who care the page
sequence, this will also prevent tiff2pdf from creating pdf file from
the merged tiff file with wrong page sequence.
2010-05-08 Olivier Paquet <olivier.paquet@gmail.com>
* libtiff/tif_dirread.c: Restored TIFFReadDirEntryFloat function in order
to add missing TIFF_SETGET_FLOAT case to TIFFFetchNormalTag.
* libtiff/tif_dirinfo.c: Use correct set_field_type for
TIFFTAG_PIXAR_FOVCOT so it is readable again (regression from 3.9.2).
http://bugzilla.maptools.org/show_bug.cgi?id=2192
2010-05-07 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_jpeg.c: Ensure that quality is always set in
JPEGPreEncode(), not just when we want to output local tables.
Otherwise the quality used during compression may not be right and
might not match the tables in the tables tag. This bug only occurs
when seeking between directories in the midst of writing blocks.
http://trac.osgeo.org/gdal/ticket/3539
2010-05-06 Andrey Kiselev <dron@ak4719.spb.edu>
* html/man/TIFFGetField.3tiff.html, html/man/TIFFSetField.3tiff.html:
Regenerated from the source.
2010-05-05 Olivier Paquet <olivier.paquet@gmail.com>
* libtiff/tif_print.c: Fixed printing of TIFFTAG_REFERENCEBLACKWHITE which
had stopped working. Also made it always print 6 floats instead of
2*SamplesPerPixel.
http://bugzilla.maptools.org/show_bug.cgi?id=2191
http://bugzilla.maptools.org/show_bug.cgi?id=2186
* man/TIFFGetField.3tiff, man/TIFFSetField.3tiff: Fixed doc to reflect the
fact that libtiff considers TIFFTAG_REFERENCEBLACKWHITE to be 6 floats.
2010-05-05 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_jpeg.c: Fix to use memcmp(), not memcpy() when checking
if the jpeg table was written. This is a fix for the last fix on 04-21.
2010-04-21 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_jpeg.c: avoid preparing jpeg tables everytime
JPEGSetupEncode() is called if the tables already seem to be
established. This prevents spurious updates and rewriting of
directories with jpegtables when doing updates to existing images.
http://trac.osgeo.org/gdal/ticket/3539
2010-04-20 Olivier Paquet <olivier.paquet@gmail.com>
* libtiff/tif_dirinfo.c: Use correct set_field_type for
TIFFTAG_PIXAR_IMAGEFULLWIDTH, TIFFTAG_PIXAR_IMAGEFULLLENGTH,
TIFFTAG_PIXAR_MATRIX_WORLDTOSCREEN and TIFFTAG_PIXAR_MATRIX_WORLDTOCAMERA.
They were unreadable with TIFF_SETGET_UNDEFINED, a regression from 3.9.2.
http://bugzilla.maptools.org/show_bug.cgi?id=2139
2010-04-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff/tif_dir.c (_TIFFVSetField): Add a special error case for
when the tag count value is zero. Error handling is still a
regression since in 3.9.2, empty tags are skipped (with a warning)
rather than returning a hard error and refusing to read the file.
* tools/ppm2tiff.c (main): While case for parsing comment line
requires extra parenthesis to work as expected. Reported by
Thomas Sinclair.
2010-04-02 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_read.c (primarily): Add support for
CHUNKY_STRIP_READ_SUPPORT where large strips are
read in chunks for applications using TIFFReadScanline().
This is intended to make it more practical work with very
large compressed one-strip files. Feature is off by default.
Enable by defining CHUNK_STRIP_READ_SUPPORT as a macro.
http://trac.osgeo.org/gdal/ticket/3514
2010-03-31 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_flush.c: Use TIFFRewriteDirectory() when flushing
directories so previously placed directories will be migrated to
the end of file if needed.
2010-03-30 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_lzw.c: change type of dec_bitsleft field to uint64
to support operating on strips/tiles of more than 256MB.
http://trac.osgeo.org/gdal/ticket/3512
2010-03-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff/tif_aux.c (_TIFFCheckRealloc): Improve error message so
that it is clearly a memory allocation error message, and also
includes the size of the allocation request.
2010-02-22 Lee Howard <faxguy@howardsilvan.com>
* libtiff/tif_jpeg.c: Do not generate a JPEGTables tag when creating
the JPEG TIFF as is is not required in order to prevent it from
being unused and filled with invalid data. (Leave it to be
generated by later activity.)
http://bugzilla.maptools.org/show_bug.cgi?id=2135
* tools/tiff2pdf.c: Write the JPEG SOI headers into the TIFF strip
data rather than skipping them. This fixes the ability to view in
Acrobat Reader, Evince, and Ghostscript.
http://bugzilla.maptools.org/show_bug.cgi?id=2135
* libtiff/tif_fax3.c: Don't return error on badly-terminated MMR
strips.
http://bugzilla.maptools.org/show_bug.cgi?id=2029
2009-12-03 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_jpeg.c: Made JPEGDecodeRaw() check for buffer overruns.
Made so that when working with downsampled images a stub function
reporting an error is used for tif_decoderow. We cannot meaningfully
support reading scanlines in this situation. (#1936)
* libtiff/tif_jpeg.c: Ensure that tif_scanlinesize is computed after
resetting of the upsampling values (gdal:#3259).
http://bugzilla.maptools.org/show_bug.cgi?id=1936
2009-11-30 Frank Warmerdam <warmerdam@pobox.com>
* contrib/dbs/tiff-grayscale.c, contrib/tif-palette.c,
tools/ras2tiff.c: Fix resource leaks on error.
http://bugzilla.maptools.org/show_bug.cgi?id=2121
* libtiff/tif_{aux.c,dir.c,dir.h,dirinfo.c}: Return to handling
TIFFTAG_REFERENCEBLACKWHITE as a field in the TIFF directory instead
of as a custom(generic) field to avoid a potential reentrancy problem.
http://bugzilla.maptools.org/show_bug.cgi?id=2125
* libtiff/tif_color.c, libtiff/tif_getimage.c, libtiff/tiffio.h,
man/TIFFcolor.3tiff: Make TIFFDisplay argument in TIFFCIELabToRGBInit
const, and display_sRGB static and const.
http://bugzilla.maptools.org/show_bug.cgi?id=2124
2009-11-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

2009-09-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* tools/tiffcrop.c, man/tiffcrop.1: New tiffcrop from Richard
Nolde. Major updates to add significant functionality for reading
and writing tile based images with bit depths not a multiple of 8
which cannot be handled by tiffcp.
2009-09-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* libtiff/tif_ojpeg.c (OJPEGWriteHeaderInfo): IJG JPEG 7 needs

caller. Register a private error callback to accomplish that.
* test/Makefile.am (TIFFIMAGES): Add test images in BMP, GIF, and
PNM formats so that we will be able to test more of the tools.
While adding these test images I notice that bmp2tiff and gif2tiff

2009-08-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* test/Makefile.am, test/tiffcrop*.sh: Split previously existing
tiffcrop.sh into a collection of many specific tests. Re-wrote
all of the existing tests to be based on some simple shell
functions. Make distcheck works again.
Export certain variables (MAKE, MAKEFLAGS, MEMCHECK) to tests and
added 'memcheck' and 'ptrcheck' targets to make it easy to run the
tests under valgrind.
2009-08-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* test/tiffcp-logluv.sh: Fix test so that it works with a VPATH
build.
* test/Makefile.am (AUTOMAKE_OPTIONS): Colorized tests was not
actually activated since it needed to be enabled in this
Makefile.am. Also activated parallel-tests mode since it offers
useful features such as per-test .log files and a summary test

depending on whether the file is bigtiff or classic tiff.
http://bugzilla.maptools.org/show_bug.cgi?id=1917
2008-08-12 Edward Lam <edward@sidefx.com>
* tools/tiffdump.c: When compiling for Microsoft Windows, apply
consistent (__int64) casting when testing if _lseeki64 has
successfully seeked as requested. This is necessary for large
file support to work since off_t is only 32-bit.
2008-07-29 Frank Warmerdam <warmerdam@pobox.com>
* tif_strip.c: Replace assertions related to samplesperpixel != 3 or
the subsampling values not being 1, 2 or 4 (for jpeg compressed images)

* libtiff/tif_dirinfo.c: Use TIFF_SETGET_ASCII for PIXAR_TEXTUREFORMAT
and PIXAR_WRAPMODES instead of TIFF_SETGET_UNDEFINED. Not exactly clear
why this is needed.
2008-05-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* Makefile.am (ACLOCAL_AMFLAGS): Libtool 2.2.4 does not like
"ACLOCAL_AMFLAGS=-I ./m4". It wants "ACLOCAL_AMFLAGS=-I m4".
2008-04-15 Andrey Kiselev <dron@ak4719.spb.edu>
* test/: Test suite updated. Everything is passed now.
* libtiff/tif_dirinfo.c: Fixed description of the
TIFFTAG_NUMBEROFINKS tag.
2008-04-14 Andrey Kiselev <dron@ak4719.spb.edu>
* libtiff/{tif_dirread.c, tif_dirwrite.c, tiffiop.h}:
Get rid of some of "dereferencing type-punned" warnings by converting
tdir_offset field of TIFFDirEntry structure into union.
2008-04-10 Andrey Kiselev <dron@ak4719.spb.edu>
* libtiff/{tif_flush.c, tif_dirwrite.c, tiffio.h, tiffiop.h}:
TIFFRewriteField() renamed into _TIFFRewriteField() and moved out
from the public interface. Type of its 'count' parameter changed
from uint32 to tmsize_t.
* /libtiff/tiffiop.h: Make tif_nfields and tif_nfieldscompat fields
of the tiff structure have the size_t type instead of uint32.
2008-04-09 Andrey Kiselev <dron@ak4719.spb.edu>
* tools/tiffdump.c: Added support for MSVS 6.0.
* libtiff/tif_dirread.c: Use custom functions _TIFFUInt64ToFloat()
and _TIFFUInt64ToDouble() to convert 64-bit integers into floating
point values on MSVS 6.0 platform.
2008-03-14 Frank Warmerdam <warmerdam@pobox.com>
* tif_dirread.c: Removed sanity checks on tags larger than 4MB in
TIFFReadDirEntryArray() since they are interfering with seemingly
legitimate files. http://trac.osgeo.org/gdal/ticket/2005
2008-02-09 Joris Van Damme <joris.at.lebbeke@skynet.be>
* tif_dirread.c: Added handling for the case of number of values for
PageNumber tag different from 2 (previously resulted in an assert
indicating lack of handling and was forgotten about)
2008-02-01 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_jpeg.c: Do not try to fixup subsampling tags based on
the actual jpeg data stream if the first strip/tile has zero size.
This is the case when GDAL creates a new file with zero sizes, closes
and reopens it.
2008-01-07 Frank Warmerdam <warmerdam@pobox.com>
* tools/tiff2ps.c: fix up 64bit issues (from Edward Lam).
2008-01-01 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_dirwrite.c: #ifdef out lots of unused functions.
* Makefile.vc, libtiff/Makefile.vc, tools/Makefile.vc: Improve clean
targets.
* tools/tiffinfo.c, tools/tiffcmp.c, tools/gif2tiff.c, tools/bmp2tiff.c
tools/tiff2pdf.c: Fix 64-bit warnings when compiling under MSVC 2005
(x64).
* tools/tiffset.c: Changes to reflect the fact that TIFFFieldWithTag()
and TIFFFieldWithName() now return TIFFField pointers instead of
TIFFFieldInfo pointers.
* tools/tiffdump.c: Added ssize_t typedef on Windows since it doesn't
exist. This makes it compile again on Windows
* tif_aux.c, tif_getimage.c, tif_next.c, tif_predict.c, tif_win32.c,
tiffconf.vc.h: Various 64bit fixes from Edward Lam identified on win64.
* test/rewrite_tag.c: New test for TIFFRewriteField().
2007-12-31 Frank Warmerdam <warmerdam@pobox.com>
* tif_dirwrite.c: Added TIFFRewriteField(). This new function
rewrites one field "on disk" updating an existing directory
entry. Lots of limitations still...
* tiffiop.h, tif_write.c, tif_dirread.c, tif_flush.c: Keep track of
TIFF_DIRTYSTRIP separately from TIFF_DIRTYDIRECT to indicate that
the strip offset/size values are dirty but nothing else about the
directory is dirty. In flush handle "just stripmaps dirty" as a
special case that just rewrites these values without otherwise
modifying the directory on disk using TIFFRewriteField().
We also modify logic so that in update mode the directory is not
marked dirty on read, but only when something is changed. This
means we need to keep track of updates to the stripmap stuff in
TIFFAppendToStrip().
2007-12-10 Frank Warmerdam <warmerdam@pobox.com>
* tif_jpeg.c: Improve ability to switch between encoding and decoding
in the jpeg code (gdal bug #2033).
2007-11-23 Frank Warmerdam <warmerdam@pobox.com>
* tif_dir.c, tif_dirread.c, tif_dirwrite.c, tif_read.c, tif_write.c,
tiffiop.h: Added TIFF_BUF4WRITE flag to indicate if contents of the
rawcp/rawcc buffer are for writing and thus may require flushing.
Necessary to distinguish whether they need to be written to disk when
in mixed read/write mode and doing a mixture of writing followed by
reading. http://trac.osgeo.org/gdal/ticket/1758
2007-11-23 Andrey Kiselev <dron@ak4719.spb.edu>
* configure.com, libtiff/tif_vms.c: Better OpenVMS support. Patches
from Alexey Chupahin.
2007-11-02 Frank Warmerdam <warmerdam@pobox.com>
* tif_write.c: Rip out the fancy logic in TIFFAppendToStrip() for
establishing if an existing tile can be rewritten to the same location
by comparing the current size to all the other blocks in the same
directory. This is dangerous in many situations and can easily
corrupt a file. (observed in esoteric GDAL situation that's hard to
document). This change involves leaving the stripbytecount[] values
unaltered till TIFFAppendToStrip(). Now we only write a block back
to the same location it used to be at if the new data is the same
size or smaller - otherwise we move it to the end of file.
* tif_dirwrite.c: Try to avoid writing out a full readbuffer of tile
data when writing the directory just because we have BEENWRITING at
some point in the past. This was causing odd junk to be written out
in a tile of data when a single tile had an interleaving of reading
and writing with reading last. (highlighted by gdal
autotest/gcore/tif_write.py test 7.
* tif_predict.c: use working buffer in PredictorEncodeTile to avoid
modifying callers buffer.
http://trac.osgeo.org/gdal/ticket/1965
* tif_predict.c/h: more fixes related to last item, keeping a
distinct pfunc for encode and decode cases as these were getting
mixed up sometimes.
http://trac.osgeo.org/gdal/ticket/1948
2007-11-01 Frank Warmerdam <warmerdam@pobox.com>
* tif_predict.c/h, tif_lzw.c, tif_zip.c: Improvements so that
predictor based encoding and decoding works in read-write update
mode properly.
http://trac.osgeo.org/gdal/ticket/1948
2007-10-24 Joris Van Damme <joris.at.lebbeke@skynet.be>
* tif_dirread.c: Fixed problem with bogus file triggering
assert(td->td_planarconfig == PLANARCONFIG_CONTIG) in
ChopUpSingleUncompressedStrip
2007-10-22 Joris Van Damme <joris.at.lebbeke@skynet.be>
* tif_jpeg.c: Resolved buffer incrementation bug that lead to faulty images
at best, access violation at worst, when subsampled JPEG compressed imagery
is decoded without the JPEG_COLORMODE feature
2007-10-11 Frank Warmerdam <warmerdam@pobox.com>
* html/index.html: Update "people responsible" section.
2007-10-05 Frank Warmerdam <warmerdam@pobox.com>

as reported on the mailing list.
2007-10-01 Joris Van Damme <joris.at.lebbeke@skynet.be>
* changed some more incorrect %lud printf flags to %lu
2007-09-29 Joris Van Damme <joris.at.lebbeke@skynet.be>
* tif_dirread.c: Strip chopping interfered badly with uncompressed
subsampled images because it tried to divide subsampled rowblocks,
leading to all sorts of errors throughout the library for these
images. Fixed by making strip chopping divide in row counts that
are a multiple of vertical subsampling value.
2007-09-28 Joris Van Damme <joris.at.lebbeke@skynet.be>
* tif_dirread.c: Logical cast working around compiler warning
* tif_read.c: Correction of some error flags and parameter lists
2007-09-27 Joris Van Damme <joris.at.lebbeke@skynet.be>
* tif_dirread.c: Made calculation of td_maxsamplevalue more robust
when dealing with large bitspersample values, shutting up purification
tools that warn about truncation, though it remains incorrect and
indicates a conceptual problem there.
* tif_open.c: Moved early exit in case of 'h' flag (to disable reading
of first IFD) to proper place because it badly interfered with memory
mapping, resulting in mapping flag even with dummy mapping functions
that returned 0 whilst at the same time the mapping tif_size wasn't
set, thus resulting in continuous incorrect beyond-eof errors.
2007-09-24 Joris Van Damme <joris.at.lebbeke@skynet.be>
* tif_dirinfo.c: Fixed (MSVC) compiler reports about
inconsistent use of const in tiffFields and exifFields definition
2007-09-20 Frank Warmerdam <warmerdam@pobox.com>
* tif_dirwrite.c: Always write tile/strip offsets and sizes
using LONG8 type when output format is BigTIFF. The
TIFFWriteDirectoryTagLongLong8Array() function was restructured
accordingly.
* tif_dirread.c: Improvements to error reporting text in
TIFFFetchDirectory().
2007-09-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* test/images: Added a small collection of test images for use by
test programs and scripts.
* test/tiffinfo.sh: A trivial example test script.
* test/common.sh: Added small script for setting the environment
used by script-based tests.
2007-08-24 Frank Warmerdam <warmerdam@pobox.com>
* tif_dirwrite.c: Write the tif_nextdiroff value instead of a fixed
zero when writing directory contents to preserve the ability to
rewrite directories in place, even in the middle of a directory
chain.
* tif_dirinfo.c: _TIFFMergeFields() now only merges in field
definitions that are missing. Existing definitions are silently
ignored.
* tif_dirread.c: Add runtime error for fields for which no definition
is found (in addition to an assert for developers) in
TIFFFetchNormalTag(). Not sure if this is needed, but it seems
prudent.
2007-08-10 Joris Van Damme <joris.at.lebbeke@skynet.be>
* libtiff/tif_getimage.c: removed SubsamplingHor and SubsamplingVer
from _TIFFRGBAImage structure to revert unwanted ABI change.
2007-08-10 Joris Van Damme <joris.at.lebbeke@skynet.be>
* libtiff/tif_win32.c: use SetFilePointer instead of

inside extern "C" block.
* libtiff/{tif_lzw.c, tif_luv.c, tif_dumpmode.c, tif_print.c,
tif_read.c, tif_strip.c, tif_thunder.c}: Use "%I64d" printf()
formatter instead of "%lld" with MSVC compiler.

TIFFReassignTagToIgnore() function and TIFFIgnoreSense enumeration
removed.
* libtiff/{tif_dirinfo.c, tif_fax3.c, tif_jbig.c, tif_jpeg.c}: Move
tags TIFFTAG_FAXRECVPARAMS, TIFFTAG_FAXSUBADDRESS,
TIFFTAG_FAXRECVTIME and TIFFTAG_FAXDCS to the common tag directory.
These tags are not codec-specific and relate to image content, so
process them as other normal tags.
* libtiff/{tiffio.h, tif_dir.h}: TIFFTagValue structure moved from the
public tiffio.h to private tif_dir.h.
* contrib/{acorn, mac-cw, mac-mpw}: Removed as unmaintained and
outdated.
2007-07-03 Andrey Kiselev <dron@ak4719.spb.edu>
* libtiff{tif_acorn.c, tif_apple.c, tif_atari.c, tif_msdos.c,
tif_win3.c}: Obsoleted portability stuff removed.

significant upgrade of the whole utility as per bug
http://bugzilla.remotesensing.org/show_bug.cgi?id=1560
Now we don't need tiffiop.h in tiff2pdf anymore and will open output
PDF file using TIFFClientOpen() machinery as it is implemented
by Leon Bottou.
2007-06-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* configure.ac: Fix typo when substituting value for unsigned 8 bit type.
Added support for a TIFF_PTRDIFF_T type to use when doing pointer arithmetic.
Added support for a TIFF_SSIZE_T in order to return memory sizes but still
allow returning -1 for errors.
* libtiff/tiffconf.vc.h: Add porting type defintions for WIN32.

tif_fax3.c, tif_jbig.c, tif_luv.c, tif_ojpeg.c, tif_pixarlog.c,
tif_predict.c, tif_zip.c}: Finally fix bug
http://bugzilla.remotesensing.org/show_bug.cgi?id=1274
by introducing _TIFFMergeFieldInfo() returning integer error status
instead of void in case of problems with field merging (e.g., if the
field with such a tag already registered). TIFFMergeFieldInfo() in
public API remains void. Use _TIFFMergeFieldInfo() everywhere and
check returned value.
2007-04-07 Frank Warmerdam <warmerdam@pobox.com>
* contrib/addtiffo/tif_overview.c: Fix problems with odd sized output
blocks in TIFF_DownSample_Subsampled() (bug 1542).
2007-04-06 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/tif_jpeg.c: Changed JPEGInitializeLibJPEG() so that it
will convert from decompressor to compressor or compress to decompress
if required by the force arguments. This works around a problem in
where the JPEGFixupTestSubsampling() may cause a decompressor to
be setup on a directory when later a compressor is required with the
force flag set. Occurs with the addtiffo program for instance.

problems with predictor initialization. Remove O_RDONLY check during
state block allocation to be able open LZW compressed files in update

* libtiff/tif_write.c: modified tif_write.c so that the various
encoded write functions use tif_postdecode() to apply byte order
swapping (swab) to the application passed data buffer if the same
would be done when reading. This allows us to write pixel data with
more than 8 bits per sample to existing files of a non-native byte
order. One side effect of this change is the applications buffer
itself is altered in this case by the act of writing.

tiles files to avoid error about it not matching the
cinfo.d.image_width values ("JPEGPreDecode: Improper JPEG strip/tile
size.") for ITIFF files. Apparently the problem was incorporated since
3.5.5, presumably during the OJPEG/JPEG work recently.
2001-12-15 Frank Warmerdam <warmerdam@pobox.com>
* configure, libtiff/Makefile.in: Changes for building on MacOS 10.1.
http://bugzilla.remotesensing.org/show_bug.cgi?id=94
* libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1
(defined in tiffconf.h - 1 by default) then the RGBA interface
will assume that a fourth extra sample is ASSOCALPHA if the
EXTRASAMPLE value isn't set for it. This changes the behaviour of
the library, but makes it work better with RGBA files produced by
lots of applications that don't mark the alpha values properly.

* configure, Makefile.in, etc: added support for OPTIMIZER being
set from config.site.
2001-03-28 Frank Warmerdam <warmerdam@pobox.com>
* fax2ps.c: Helge (libtiff at oldach.net) submitted fix:
Here's a fix for fax2ps that corrects behaviour for non-Letter paper
sizes. It fixes two problems:
Without scaling (-S) the fax is now centered on the page size specified
with -H and/or -W. Before, fax2ps was using an obscure and practially
useless algorithm to allocate the image relative to Letter sized paper
which sometime sled to useless whitespace on the paper, while at the
same time cutting of the faxes printable area at the opposite border.
Second, scaling now preserves aspect ratio, which makes unusual faxes
(in particular short ones) print properly.
See http://bugzilla.remotesensing.org/show_bug.cgi?id=35
* tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by
Bruce A. Mallett. See check message for detailed information
on all the changes, including a faster encoder, fixes for level
2 PostScript, and support for the imagemask operator.
2001-03-27 Frank Warmerdam <warmerdam@pobox.com>

* libtiff/libtiff.def: Brent Roman submitted new version adding
serveral missing entry points.
* libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS.
Some sort of weird VMS thing.
http://bugzilla.remotesensing.org/show_bug.cgi?id=31
* tif_luv.c/tiff.h/tiffio.h:
New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward
(greg@shutterfly.com). He writes:
1) I improved the gamut-mapping function in tif_luv.c for imaginary
colors, because some images were being super-saturated on the input
side and this resulted in some strange color shifts in the output.
2) I added a psuedotag in tiff.h to control random dithering during
LogLuv encoding. This is turned off by default for 32-bit LogLuv and
on for 24-bit LogLuv output. Dithering improves the average color
accuracy over the image.
3) I added a #define for LOG_LUV_PUBLIC, which is enabled by default in
tiffio.h, to expose internal routines for converting between LogLuv and
XYZ coordinates. This is helpful for writing more efficient,
specialized conversion routines, especially for reading LogLuv files.
Changes applied with minor edits.
2001-01-23 Frank Warmerdam <warmerdam@pobox.com>
* tif_fax3.c: keep rw_mode flag internal to fax3 state to remember
whether we are encoding or decoding. This is to ensure graceful
recovery if TIFFClientOpen() discovers an attempt to open a compressed
file for "r+" access, and subsequently close it, as it resets the
tif_mode flag to O_RDONLY in this case to avoid writes, confusing the
compressor's concept of whether it is in encode or decode mode.
2001-01-08 Mike Welles <mike@bangstate.com>
* Makefile.in: Now cleaning up after itself after creating the .tar.gz and .zip
2001-01-07 Frank Warmerdam <warmerdam@pobox.com>

2000-11-24 Frank Warmerdam <warmerdam@pobox.com>
* libtiff/Makefile.in: Added an installPrivateHdrs and install-private
target so that the private headers required by libgeotiff can be
installed with the others. They are not installed by default.
* libtiff/Makefile.in: Added @MACHLIBDEPS@ to LINUXdso and GNULDdso
targets so libtiff.so will be built with an explicit dependency
on libm.so.
* libtiff/Makefile.in: Use softlinks to link libtiff.so.3 to
libtiff.so.3.5.5.
* libtiff/Makefile.in & configure: Remove all references to the ALPHA
file, or ALPHA version logic. Added stuff about DIST_POINT in
place of DIST_TYPE and the alpha release number stuff.
2000-11-22 Frank Warmerdam <warmerdam@pobox.com>
* I have applied a patch from Steffen Moeller <moeller@ebi.ac.uk> to
the configure script so that it now accepts the --prefix, and
--exec-prefix directives.
2000-11-13 Frank Warmerdam <warmerda@cs46980-c>
* I have made a variety of modifications in an effort to ensure the
TIFFLIB_VERSION macro is automatically generated from the RELEASE-DATE
file which seems to be updated regularly.
o mkversion.c now reads RELEASE-DATE and emits TIFFLIB_VERSION in
version include file.
o renamed version.h to tiffvers.h because we now have to install it
with the public libtiff include files.
o include tiffvers.h in tiffio.h.
o updated tif_version.c to use tiffvers.h.
o Updated Makefile.in accordingly.
* As per http://bugzilla.remotesensing.org/show_bug.cgi?id=25

* Modified tif_packbits.c encoder to avoid compressing more
data than provided if rowsize doesn't factor into provided data
(such as occurs for YCbCr).
2000-10-19 Frank Warmerdam <warmerda@cs46980-c>
* tools/rgb2ycbcr.c: fixed output strip size to account for vertical
roundup if rows_per_strip not a multiple of vertical sample size.
2000-10-16 Frank Warmerdam <warmerda@cs46980-c>

output buffer, and to issue a warning if data needs to be
discarded. See http://bugzilla.remotesensing.org/show_bug.cgi?id=18
2000-10-12 Frank Warmerdam <warmerda@cs46980-c>

Patch c/o Stanislav Brabec <utx@penguin.cz>
2000-09-30 Frank Warmerdam <warmerda@cs46980-c>
* Modified TIFFClientOpen() to emit an error on an attempt to
open a comperessed file for update (O_RDWR/r+) access. This is
because the compressor/decompressor code gets very confused when
the mode is O_RDWR, assuming this means writing only. See
bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13
2000-09-27 Frank Warmerdam <warmerda@cs46980-c>

* Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
cygwin compatibility.
* Applied patch from Roman Shpount to tif_fax3.c. This seems to
be a proper fix to the buffer sizing problem. See
http://bugzilla.remotesensing.org/show_bug.cgi?id=11
