<h2>SYNOPSIS

</h2>

#include
&lt;tiffio.h&gt;

int
TIFFFieldPassCount(const TIFFField*
fip)

<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>

TIFFFieldPassCount
returns true (nonzero) if TIFFGetField and
TIFFSetField expect a count value to be passed
before the actual data pointer.

fip is a
field information pointer previously returned by
TIFFFindField, TIFFFieldWithTag, or
TIFFFieldWithName.

When a
count is required, it will be of type uint32
when TIFFFieldReadCount reports
TIFF_VARIABLE2, and of type uint16 otherwise.
(This distinction is critical for use of
TIFFGetField, but normally not so for use of
TIFFSetField.)

<h2>RETURN VALUES
<a name="RETURN VALUES"></a>
</h2>

TIFFFieldPassCount
returns an integer that is always 1 (true) or 0 (false).

TIFFFieldReadCount(const TIFFField*
fip)

<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>

TIFFFieldReadCount
returns the number of values available to be read from the
specified TIFF field; that is, the number of arguments that
should be supplied to TIFFGetField. For most field
types this is a small positive integer, typically 1 or 2,
but there are some special values: 
TIFF_VARIABLE indicates that a variable number of values
is possible; then, a uint16 count argument and
a pointer data argument must be supplied to
TIFFGetField. 
TIFF_VARIABLE2 is the same as TIFF_VARIABLE
except that the count argument must have type
uint32. 
TIFF_SPP indicates that the number of arguments is equal
to the image&rsquo;s number of samples per pixel.

fip is a
field information pointer previously returned by
TIFFFindField, TIFFFieldWithTag, or
TIFFFieldWithName.

#include

TIFFFieldWriteCount(const TIFFField*
fip)

<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>

TIFFFieldWriteCount
returns the number of values to be written into the
specified TIFF field; that is, the number of arguments that
should be supplied to TIFFSetField. For most field
types this is a small positive integer, typically 1 or 2,
but there are some special values: 
TIFF_VARIABLE indicates that a variable number of values
is possible; then, a uint16 count argument and
a pointer data argument must be supplied to
TIFFSetField. 
TIFF_VARIABLE2 is the same as TIFF_VARIABLE
except that the count argument must have type
uint32. (On most modern machines, this makes no
practical difference, and the count argument can
simply be an int in either case.) 
TIFF_SPP indicates that the number of arguments must be
equal to the image&rsquo;s number of samples per pixel.

fip is a
field information pointer previously returned by
TIFFFindField, TIFFFieldWithTag, or
TIFFFieldWithName.

For most field
types, TIFFFieldWriteCount returns the same value as
TIFFFieldReadCount, but there are some
exceptions.

<h2>SYNOPSIS
<a name="SYNOPSIS"></a>
</h2>

#include
&lt;tiffio.h&gt;

int
TIFFGetField(TIFF *tif, ttag_t
tag, ...)

#include
&lt;stdarg.h&gt;

int
TIFFVGetField(TIFF *tif, ttag_t

<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>

TIFFGetField
returns the value of a tag or pseudo-tag associated with the
the current directory of the opened TIFF file
tif. (A pseudo-tag is a parameter that is used
to control the operation of the TIFF library
but whose value is not read or written to the underlying
file.) The file must have been previously opened with
TIFFOpen(3TIFF). The tag is identified by tag,
one of the values defined in the include file tiff.h
(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 stdarg(3) interface. The returned
values should only be interpreted if TIFFGetField
returns 1.

TIFFVGetField
is functionally equivalent to TIFFGetField except
that it takes a pointer to a variable argument list.
TIFFVGetField is useful for layering interfaces on
top of the functionality provided by
TIFFGetField.

TIFFGetFieldDefaulted
and TIFFVGetFieldDefaulted are identical to
TIFFGetField and TIFFVGetField, except that if
a tag is not defined in the current directory and it has a
default value, then the default value is returned.

The tags
understood by libtiff(3TIFF), 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
TIFFSetField(3TIFF). Remember that
TIFFGetField returns parameter values, so all the
listed data types are pointers to storage where values
should be returned. Consult the TIFF
specification (or relevant industry specification) for
information on the meaning of each tag and their possible
values.

you want to read the LONG value from the tag 33424 and ASCII
string from the tag 36867 you can use the following
code:

uint16 count;

Enable the use of &lsquo;&lsquo;strip

comprised of a single strip or tile of uncompressed data.
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.

The TIFF specification (all
versions) states that compliant readers must be
capable of reading images written in either byte order.
Nonetheless some software that claims to support the reading
of TIFF images is incapable of reading images
in anything but the native CPU 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 CPU 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
&lsquo;&lsquo;b&rsquo;&rsquo; and
&lsquo;&lsquo;l&rsquo;&rsquo; option flags may be included
in the call to open a file; for example,
&lsquo;&lsquo;wb&rsquo;&rsquo; or

The routines described here provide a high-level
interface through which TIFF 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 TIFFRGBAImage 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&rsquo;s needs by
installing custom routines that manipulate image data
according to application requirements.

The default usage for these routines is: check if an
image can be processed using TIFFRGBAImageOK,
construct a decoder state block using
TIFFRGBAImageBegin, read and decode an image into a
target raster using TIFFRGBAImageGet, and then
release resources using TIFFRGBAImageEnd.
TIFFRGBAImageGet 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
TIFFRGBAImageGet as needed to display an image.

The generated raster is assumed to be an array of
width times height 32-bit entries, where
width must be less than or equal to the width of the
image (height 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 (x,y) is
raster[y*width+x]; with the
raster origin in the lower-left hand corner.)

Raster pixels are 8-bit packed red, green, blue, alpha
samples. The macros TIFFGetR, TIFFGetG,
TIFFGetB, and TIFFGetA should be used to
access individual samples. Images without Associated Alpha
matting information have a constant Alpha of 1.0 (255).

TIFFRGBAImageGet converts non-8-bit images by
scaling sample values. Palette, grayscale, bilevel,
CMYK , and YCbCr images are converted to
RGB transparently. Raster pixels are returned
uncorrected by any colorimetry information present in the
directory.

The parameter stopOnError specifies how to act if
an error is encountered while reading the image. If
stopOnError is non-zero, then an error will terminate
the operation; otherwise TIFFRGBAImageGet will
continue processing data until all the possible data in the
image have been requested.

To use the core support for reading and processing
TIFF images, but write the resulting raster
data in a different format one need only override the
&lsquo;&lsquo;put methods&rsquo;&rsquo; used to store
raster data. These methods are are defined in the
TIFFRGBAImage structure and initially setup by
TIFFRGBAImageBegin to point to routines that pack
raster data in the default ABGR pixel format.
Two different routines are used according to the physical
organization of the image data in the file:
PlanarConfiguration=1 (packed samples), and
PlanarConfiguration=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.

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
TIFFRGBAImageBegin and then invoke them before or
after each display operation. For example, the
tiffgt(1) utility uses the following put method to
update the display as the raster is being filled:

<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-&gt;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);
 }
}
</pre>

(the original routine provided by the library is saved in
the variable putContig.)

The TIFFRGBAImage routines support the most
commonly encountered flavors of TIFF. It is
possible to extend this support by overriding the
&lsquo;&lsquo;get method&rsquo;&rsquo; invoked by
TIFFRGBAImageGet to read TIFF image
data. Details of doing this are a bit involved, it is best
to make a copy of an existing get method and modify it to
suit the needs of an application.

The value of tile is a &lsquo;&lsquo;raw tile
number.&rsquo;&rsquo; That is, the caller must take into
account whether or not the data are organized in separate
planes (PlanarConfiguration=2).
TIFFComputeTile automatically does this when
converting an (x,y,z,sample) coordinate quadruple to a tile
number. To read a full tile of data the data buffer should
be at least as large as the value returned by
TIFFTileSize.

The library attempts to hide bit- and byte-ordering
differences between the image and the native machine by
converting data to the native machine order. Bit reversal is
done if the FillOrder 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,

TIFFReadRGBAImage reads a strip- or tile-based
image into memory, storing the result in the user supplied
raster. The raster is assumed to be an array of
width times height 32-bit entries, where
width must be less than or equal to the width of the
image (height 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 (x,y) is
raster[y*width+x]; with the
raster origin in the lower-left hand corner.)

TIFFReadRGBAImageOriented works like
TIFFReadRGBAImage with except of that user can
specify the raster origin position with the
orientation parameter. Four orientations
supported:

Raster pixels are 8-bit packed red, green, blue, alpha
samples. The macros TIFFGetR, TIFFGetG,
TIFFGetB, and TIFFGetA should be used to
access individual samples. Images without Associated Alpha
matting information have a constant Alpha of 1.0 (255).

TIFFReadRGBAImage converts non-8-bit images by
scaling sample values. Palette, grayscale, bilevel,
CMYK , and YCbCr images are converted to
RGB transparently. Raster pixels are returned
uncorrected by any colorimetry information present in the
directory.

The paramater stopOnError specifies how to act if
an error is encountered while reading the image. If
stopOnError is non-zero, then an error will terminate
the operation; otherwise TIFFReadRGBAImage will
continue processing data until all the possible data in the
image have been requested.

All error messages are directed to the

Compression algorithm does not support random
access. Data was requested in a non-sequential order
from a file that uses a compression algorithm and that has
RowsPerStrip greater than one. That is, data in the
image is stored in a compressed form, and with multiple rows
packed into a strip. In this case, the library does not
support random access to the data. The data should either be
accessed sequentially, or the file should be converted so
that each strip is made up of one row of data.

<h2>SYNOPSIS
<a name="SYNOPSIS"></a>
</h2>

#include
&lt;tiffio.h&gt;

int
TIFFSetField(TIFF *tif, ttag_t
tag, ...)

#include
&lt;stdarg.h&gt;

int
TIFFVSetField(TIFF *tif, ttag_t
tag, va_list ap)

<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>

TIFFSetField
sets the value of a field or pseudo-tag in the current
directory associated with the open TIFF file
tif. (A pseudo-tag is a parameter that is used
to control the operation of the TIFF 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 TIFFOpen(3TIFF);
pseudo-tags can be set whether the file was opened for
reading or writing. The field is identified by tag,
one of the values defined in the include file tiff.h
(see also the table below). The actual value is specified
using a variable argument list, as prescribed by the
stdarg(3) interface (or, on some machines, the
varargs(3) interface.)

TIFFVSetField
is functionally equivalent to TIFFSetField except
that it takes a pointer to a variable argument list.
TIFFVSetField is useful for writing routines that are
layered on top of the functionality provided by
TIFFSetField.

The tags
understood by libtiff, the number of parameter
values, and the expected types for the parameter values are
shown below. The data types are: char* is
null-terminated string and corresponds to the
ASCII data type; uint16 is an unsigned
16-bit value; uint32 is an unsigned 32-bit value;
uint16* is an array of unsigned 16-bit values.
void* is an array of data values of unspecified
type.

Consult the
TIFF specification for information on the
meaning of each tag.

</h2>

All error
messages are directed to the TIFFError(3TIFF)
routine.

%s: Cannot
modify tag &quot;%s&quot; while writing. Data has
already been written to the file, so the specified
tag&rsquo;s value can not be changed. This restriction is
applied to all tags that affect the format of written
data.

%d: Bad

TIFFWarning invokes the library-wide warning
handler function to (normally) write a warning message to
the stderr. The fmt parameter is a
printf(3S) format string, and any number arguments
can be supplied. The module 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.

Applications that desire to capture control in the event
of a warning should use TIFFSetWarningHandler to
override the default warning handler. A NULL
(0) warning handler function may be installed to suppress
error messages.

Write data to a file at the specified row. The
sample parameter is used only if data are organized
in separate planes (PlanarConfiguration=2). The data
are assumed to be uncompressed and in the native bit- and
byte-order of the host machine. The data written to the file
is compressed according to the compression scheme of the
current TIFF directory (see further below).
If the current scanline is past the end of the current
subfile, the ImageLength field is automatically
increased to include the scanline (except for
PlanarConfiguration=2, where the ImageLength
cannot be changed once the first data are written). If the
ImageLength is increased, the StripOffsets and
StripByteCounts fields are similarly enlarged to
reflect data written past the previous end of image.

The library writes encoded data using the native machine
byte order. Correctly implemented TIFF
readers are expected to do any necessary byte-swapping to
correctly process image data with BitsPerSample greater than
8. The library attempts to hide bit-ordering differences
between the image and the native machine by converting data
from the native machine order.

In C++ the sample parameter defaults to 0.

Once data are written to a file for the current
directory, the values of certain tags may not be altered;
see TIFFSetField(3TIFF) for more information.

It is not possible to write scanlines to a file that uses
a tiled organization. The routine TIFFIsTiled can be
used to determine if the file is organized as tiles or
strips.

%s: File not open for writing . The file was
opened for reading, not writing.

Can not write scanlines to a tiled image. An
attempt was made to write a scanline to a tiled image. The
image is assumed to be organized in tiles because the
TileWidth and TileLength tags have been set
with TIFFSetField(3TIFF).

Compression algorithm does not support random
access. Data was written in a non-sequential order to a
file that uses a compression algorithm and that has
RowsPerStrip greater than one. That is, data in the
image is to be stored in a compressed form, and with
multiple rows packed into a strip. In this case, the library
does not support random access to the data. The data should
either be written as entire strips, sequentially by rows, or
the value of RowsPerStrip should be set to one.

%s: Must set &quot;ImageWidth&quot; before writing
data. The image&rsquo;s width has not be set before the
first write. See TIFFSetField(3TIFF) for information
on how to do this.

%s: Must set &quot;PlanarConfiguration&quot; before
writing data. The organization of data has not be
defined before the first write. See
TIFFSetField(3TIFF) for information on how to do
this.

Can not change &quot;ImageLength&quot; when using
separate planes. Separate image planes are being used
(PlanarConfiguration=2), but the number of rows has
not been specified before the first write. The library
supports the dynamic growth of an image only when data are
organized in a contiguous manner
(PlanarConfiguration=1).

%d: Sample out of range, max %d. The sample
parameter was greater than the value of the SamplesPerPixel
tag.

%s: No space for strip arrays . There was not
enough space for the arrays that hold strip offsets and byte

The following routines are provided for client-control of
the I/O buffers used by the library. Applications need never
use these routines; they are provided only for
&lsquo;&lsquo;intelligent clients&rsquo;&rsquo; that wish to
optimize memory usage and/or eliminate potential copy
operations that can occur when working with images that have
data stored without compression.

TIFFReadBufferSetup sets up the data buffer used
to read raw (encoded) data from a file. If the specified
pointer is NULL (zero), then a buffer of the
appropriate size is allocated. Otherwise the caller must
guarantee that the buffer is large enough to hold any
individual strip of raw data. TIFFReadBufferSetup
returns a non-zero value if the setup was successful and
zero otherwise.

TIFFWriteBufferSetup sets up the data buffer used
to write raw (encoded) data to a file. If the specified
size is &minus;1 then the buffer size is selected to
hold a complete tile or strip, or at least 8 kilobytes,
whichever is greater. If the specified buffer is
NULL (zero), then a buffer of the appropriate
size is dynamically allocated. TIFFWriteBufferSetup
returns a non-zero value if the setup was successful and
zero otherwise.

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 TIFFRGBAImage(3TIFF) interface.

TIFFYCbCrToRGBInit() used to initialize
YCbCr to RGB conversion state. Allocating and

luma 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). TIFFTAG_YCBCRCOEFFICIENTS holds
that values in TIFF file. refBlackWhite 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).
TIFFTAG_REFERENCEBLACKWHITE is responsible for
storing these values in TIFF file. Following code snippet

TIFFDefaultStripSize returns the number of rows
for a reasonable-sized strip according to the current
settings of the ImageWidth, BitsPerSample,
SamplesPerPixel, tags and any compression-specific
requirements. If the estimate 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 RowsPerStrip tag. In
lieu of any unusual requirements TIFFDefaultStripSize
tries to create strips that have approximately 8 kilobytes
of uncompressed data.

TIFFStripSize returns the equivalent size for a
strip of data as it would be returned in a call to
TIFFReadEncodedStrip or as it would be expected in a
call to TIFFWriteEncodedStrip.

TIFFVStripSize returns the number of bytes in a
strip with nrows rows of data.

TIFFRawStripSize returns the number of bytes in a
raw strip (i.e. not decoded).

TIFFComputeStrip returns the strip that contains
the specified coordinates. A valid strip is always returned;
out-of-range coordinate values are clamped to the bounds of
the image. The row parameter is always used in
calculating a strip. The sample parameter is used
only if data are organized in separate planes
(PlanarConfiguration=2).

TIFFNumberOfStrips returns the number of strips in
the image.

TIFFDefaultTileSize returns the pixel width and
height of a reasonable-sized tile; suitable for setting up
the TileWidth and TileLength tags. If the
tw and th 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
TIFF specification.

TIFFTileSize returns the equivalent size for a
tile of data as it would be returned in a call to
TIFFReadTile or as it would be expected in a call to
TIFFWriteTile.

TIFFVTileSize returns the number of bytes in a
row-aligned tile with nrows of data.

TIFFTileRowSize returns the number of bytes of a
row of data in a tile.

TIFFComputeTile returns the tile that contains the
specified coordinates. A valid tile is always returned;
out-of-range coordinate values are clamped to the bounds of
the image. The x and y parameters are always
used in calculating a tile. The z parameter is used
if the image is deeper than 1 slice
(ImageDepth&gt;1). The sample parameter is
used only if data are organized in separate planes
(PlanarConfiguration=2).

TIFFCheckTile returns a non-zero value if the
supplied coordinates are within the bounds of the image and
zero otherwise. The x parameter is checked against
the value of the ImageWidth tag. The y
parameter is checked against the value of the
ImageLength tag. The z parameter is checked
against the value of the ImageDepth tag (if defined).
The sample parameter is checked against the value of
the SamplesPerPixel parameter if the data are
organized in separate planes.

TIFFNumberOfTiles returns the number of tiles in
the image.

fax2ps reads one or more TIFF
facsimile image files and prints a compressed form of
PostScript on the standard output that is suitable for
printing.

By default, each page is scaled to reflect the image
dimensions and resolutions stored in the file. The
&minus;x and &minus;y options can be used to
specify the horizontal and vertical image resolutions
(lines/inch), respectively. If the &minus;S 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
&minus;W and &minus;H options.

By default fax2ps generates PostScript for all
pages in the file. The &minus;p option can be used to
select one or more pages from a multi-page document.

fax2ps 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
image 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 tiff2ps(1).

Some messages about malformed TIFF images
come from the TIFF library.

Various messages about badly formatted facsimile images
may be generated due to transmission errors in received
facsimile. fax2ps attempts to recover from such data
errors by resynchronizing decoding at the end of the current
scanline. This can result in long horizontal black lines in
the resultant PostScript image.

Fax2tiff creates a TIFF file
containing CCITT Group 3 or Group 4 encoded
data from one or more files containing
&lsquo;&lsquo;raw&rsquo;&rsquo; Group 3 or Group 4 encoded
data (typically obtained directly from a fax modem). By
default, each row of data in the resultant
TIFF 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
TIFF Class F ( FAX )
specification for storing facsimile data. This means, in
particular, that each page of the data does not
include the trailing return to control (
RTC ) code; as required for transmission by
the CCITT Group 3 specifications. The old,
&lsquo;&lsquo;classic&rsquo;&rsquo;, format is created if
the &minus;c option is used. (The Class F format can
also be requested with the &minus;f option.)

The default name of the output image is fax.tif;
this can be changed with the &minus;o 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.

<td width="91%">
<big>libtiff is a library for reading and writing
data files encoded with the Tag Image File 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>

<big>The library supports several compression algorithms,
as indicated by the Compression 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 &amp; 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
ThunderScan program (32809) (decompression only),
NeXT&rsquo;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&minus;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
BitsPerSample, Compression,
MinSampleValue, or MaxSampleValue fields are
defined differently on a per-sample basis (in Rev. 6.0 the
Compression tag is not defined on a per-sample basis,
so this is immaterial).</big>

<big>The library 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</big> TIFF
<big>format. The following typedefs are exposed to users
either through function definitions or through parameters
passed through the varargs interfaces.</big></td>

<big>Note that tstrip_t, ttile_t, and
tsize_t are constrained to be no more than 32-bit
quantities by 32-bit fields they are stored in in the</big>
TIFF <big>image. Likewise tsample_t is limited by the
16-bit field used to store the SamplesPerPixel tag.
tdir_t constrains the maximum number of</big> IFDs
<big>that may appear in an image and may be an arbitrary
size (w/o penalty). ttag_t 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.
toff_t is defined as int32 because TIFF file offsets
are (unsigned) 32-bit quantities. A signed value is used
because some interfaces return &minus;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>

algorithm (Compression=32773), and with each strip no
more than 8 kilobytes. These characteristics can be
overridden, or explicitly specified with the options

raw2tiff 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&rsquo;t guess the
header size, number of bands and data type, so it should be
specified manually. If you don&rsquo;t know anything about
your image, just try with the several combinations of those
options.

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.

Tiff2bw converts an RGB or Palette
color TIFF image to a greyscale image by
combining percentages of the red, green, and blue channels.
By default, output samples are created by taking 28% of the
red channel, 59% of the green channel, and 11% of the blue
channel. To alter these percentages, the &minus;R,
&minus;G, and &minus;B options may be
used.

tiff2pdf opens a TIFF image and writes a PDF
document to standard output.

The program converts one TIFF file to one PDF file,
including multiple page TIFF files, tiled TIFF files, black
and white. grayscale, and color TIFF files that contain data
of TIFF photometric interpretations of bilevel, grayscale,
RGB, YCbCr, CMYK separation, and ICC L*a*b* as supported by
libtiff and PDF.

If you have multiple TIFF files to convert into one PDF
file then use tiffcp 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.

The standard output is standard output. Set the output
file name with the &minus;o output.pdf
option.

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, libtiff CCITT support is
assumed.

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
&minus;j or &minus;z options. JPEG compression
support requires that libtiff be configured with JPEG
support, and Zip/Deflate compression support requires that
libtiff be configured with Zip support, in
tiffconf.h. Use only one or the other of &minus;j and
&minus;z.

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, &minus;d and
&minus;n.

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.

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 &minus;x and &minus;y options.
The page size can be set using the &minus;p option
for paper size, or &minus;w and &minus;l 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
&minus;u option, the default unit is inch.

Various items of the output document information can be
set with the &minus;e, &minus;c,
&minus;a, &minus;t, &minus;s, and
&minus;k options. Setting the argument of the option
to &quot;&quot; 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.

tiff2ps reads TIFF images and
writes PostScript or Encapsulated PostScript (EPS) on the
standard output. By default, tiff2ps writes
Encapsulated PostScript for the first image in the specified
TIFF image file.

By default, tiff2ps will generate PostScript that
fills a printed area specified by the TIFF
tags in the input file. If the file does not contain
XResolution or YResolution tags, then the
printed area is set according to the image dimensions. The
&minus;w and &minus;h options (see below) can
be used to set the dimensions of the printed area in inches;
overriding any relevant TIFF tags.

The PostScript generated for RGB, palette,
and CMYK images uses the colorimage
operator. The PostScript generated for greyscale and bilevel
images uses the image operator. When the
colorimage 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.

Color images with associated alpha data are composited
over a white background.

Because PostScript does not support the notion of a
colormap, 8-bit palette images produce 24-bit PostScript
images. This conversion results in output that is six times
bigger than the original image and which takes a long time
to send to a printer over a serial line. Matters are even
worse for 4-, 2-, and 1-bit palette images.

Tiff2rgba 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.

Internally this program is implemented using the
TIFFReadRGBAImage() function, and it suffers any
limitations of that image. This includes limited support for
&gt; 8 BitsPerSample images, and flaws with some esoteric
combinations of BitsPerSample, photometric interpretation,
block organization and planar configuration.

The generated images are stripped images with four
samples per pixel (red, green, blue and alpha) or if the
&minus;n 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.

tiffcp combines one or more files created
according to the Tag Image File Format, Revision 6.0 into a
single TIFF file. Because the output file may
be compressed using a different algorithm than the input
files, tiffcp is most often used to convert between
different compression schemes.

By default, tiffcp will copy all the understood
tags in a TIFF directory of an input file to
the associated directory in the output file.

tiffcp can be used to reorganize the storage
characteristics of data in a file, but it is explicitly
intended to not alter or convert the image data content in
any way.

The CCITT Group 3 and Group 4 compression
algorithms can only be used with bilevel data.

Group 3 compression can be specified together with
several T.4-specific options: 1d for 1-dimensional
encoding, 2d for 2-dimensional encoding, and
fill 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
&lsquo;&lsquo;:&rsquo;&rsquo;-separated list to the
&lsquo;&lsquo;g3&rsquo;&rsquo; option; e.g. &minus;c
g3:2d:fill to get 2D-encoded data with byte-aligned EOL
codes.

LZW compression can be specified together
with a predictor 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
&lsquo;&lsquo;:&rsquo;&rsquo;-separated list to the
&lsquo;&lsquo;lzw&rsquo;&rsquo; option; e.g. &minus;c
lzw:2 for LZW compression with horizontal
differencing.

tiffcrop combines one or more files created
according to the Tag Image File Format, Revision 6.0 into a
single TIFF file. The output file may be
compressed using a different algorithm than the input files.
tiffcrop 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.

By default, tiffcrop will copy all the understood
tags in a TIFF directory of an input file to
the associated directory in the output file.

tiffcrop 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.

tiffcrop will behave exactly like tiffcp if none
of the new options are specified.

The words odd or even may be used to specify

there are. Ranges of images may be specified with a dash and

The CCITT Group 3 and Group 4 compression
algorithms can only be used with bi-level data.

Group 3 compression can be specified together with
several T.4-specific options: 1d for 1-dimensional
encoding, 2d for 2-dimensional encoding, and
fill 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
&lsquo;&lsquo;:&rsquo;&rsquo;-separated list to the
&lsquo;&lsquo;g3&rsquo;&rsquo; option; e.g. &minus;c
g3:2d:fill to get 2D-encoded data with byte-aligned EOL
codes.

LZW compression can be specified together
with a predictor 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
&lsquo;&lsquo;:&rsquo;&rsquo;-separated list to the
&lsquo;&lsquo;lzw&rsquo;&rsquo; option; e.g. &minus;c
lzw:2 for LZW compression with horizontal
differencing.

The CCITT Group 3 and Group 4 compression
algorithms can only be used with bilevel data.

Group 3 compression can be specified together with
several T.4-specific options: 1d for 1-dimensional
encoding, 2d for 2-dimensional encoding, and
fill 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
&lsquo;&lsquo;:&rsquo;&rsquo;-separated list to the
&lsquo;&lsquo;g3&rsquo;&rsquo; option; e.g. &minus;c
g3:2d:fill to get 2D-encoded data with byte-aligned EOL
codes.

LZW compression can be specified together
with a predictor 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
&lsquo;&lsquo;:&rsquo;&rsquo;-separated list to the
&lsquo;&lsquo;lzw&rsquo;&rsquo; option; e.g. &minus;c
lzw:2 for LZW compression with horizontal
differencing.

tiffdump displays directory information from files
created according to the Tag Image File Format, Revision
6.0. The header of each TIFF file (magic
number, version, and first directory offset) is displayed,
followed by the tag contents of each directory in the file.
For each tag, the name, data type, count, and value(s) is
displayed. When the symbolic name for a tag or data type is
known, the symbolic name is displayed followed by it&rsquo;s
numeric (decimal) value. Tag values are displayed enclosed
in &lsquo;&lsquo;&lt;&gt;&rsquo;&rsquo; characters
immediately preceded by the value of the count field. For
example, an ImageWidth tag might be displayed as
&lsquo;&lsquo;ImageWidth (256) SHORT (3)
1&lt;800&gt;&rsquo;&rsquo;.

tiffdump is particularly useful for investigating
the contents of TIFF files that
libtiff does not understand.

TIFFError invokes the library-wide error handling
function to (normally) write an error message to the
stderr. The fmt parameter is a
printf(3S) format string, and any number arguments
can be supplied. The module parameter, if non-zero,
is printed before the message; it typically is used to
identify the software module in which an error is
detected.

Applications that desire to capture control in the event
of an error should use TIFFSetErrorHandler to
override the default error handler. A NULL
(0) error handling function may be installed to suppress
error messages.

</UL>

<A NAME="configure">CHANGES IN THE SOFTWARE CONFIGURATION:</A>

<UL>
<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
 libc.so only be readable (not executable)
</UL>

<A NAME="libtiff">CHANGES IN LIBTIFF:</A>

<UL>
<LI>support was add for ICC: <TT>NumberOfInks</TT>, and <TT>ICCProfile</TT>
<LI>a memory leak caused by doing <TT>TIFFSetDirectory(0)</TT> was fixed
<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
<LI><TT>TIFFPrintDirectory</TT> now understands <TT>NumberOfInks</TT>
 and ICC-related tags
<LI>the routines for reading image data now provide more useful information
 when a read error is encountered
<LI>support was added for compiling with Microsoft Visual C++ 4.0
</UL>

<A NAME="tools">CHANGES IN THE TOOLS:</A>

<UL>
<LI>a bug was fixed in pal2rgb's colormap handling
<LI>tiff2ps now includes John Wehle's changes for maintaining 
 the aspect ratio
 of images when scaling and for honoring the deadzone on a page when
 generating PostScript Level II
<LI>tiff2ps does a better job guarding against the mishandling
 of greyscale images
<LI>tiff2ps now correctly converts X- and Y-resolution values
 specified in metric units
<LI>tiffdump has a new <TT>-m</TT> option to control the maximum
 number of indirect
 data values printed for a tag (by default 24)
<LI>tiffdump understands several new tags
<LI>tiffdump now shows any terminating null in ASCII strings
<LI>tiffinfo now suppresses strip chopping when interpreting an image;
 a new <TT>-z</TT> option has been added to enable strip chopping

This document describes the changes made to the software between the
previous and current versions (see above).
If you don't find something listed here, then it was not done in this
timeframe, or it was not considered important enough to be mentioned.
The following information is located here:
<UL>

<LI><A HREF="#tools">Changes in the tools</A>
</UL>
 
The ChangeLog will follow, but please note the most important change: 
LZW compression has been removed. 

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.
 
From <A HREF=http://burnallgifs.org>Burn All GIF's Day</a>:
 
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

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.

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
 
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. 
 
LZW decompression is unchanged.

</UL>

<A NAME="libtiff">CHANGES IN LIBTIFF:</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.

</UL>

<A NAME="tools">CHANGES IN THE TOOLS:</A>

<UL>

<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
	 http://bugzilla.remotesensing.org/show_bug.cgi?id=15 Patch

<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>

<A NAME="libtiff">CHANGES IN LIBTIFF:</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.

	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.

	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.

</UL>

<A NAME="tools">CHANGES IN THE TOOLS:</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:
 
	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.

<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.

<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.

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.

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!

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".

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.

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.

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

<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.

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.

</UL>

<A NAME="libtiff">CHANGES IN LIBTIFF:</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

<A NAME="highlights">MAJOR CHANGES:</A>

<UL>
	<li> New tiffcrop utility contributed by Richard Nolde.
	tiffcrop does the same as tiffcp, 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>

<A NAME="configure">CHANGES IN THE SOFTWARE CONFIGURATION:</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>

<A NAME="libtiff">CHANGES IN LIBTIFF:</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>

	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=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>

	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().

	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.

Current Version: v4.0.0 
Previous Version: <A HREF=v3.9.5.html>v3.9.5</a>

</UL>

<A NAME="highlights">MAJOR CHANGES:</A>

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.

</UL>

<A NAME="configure">CHANGES IN THE SOFTWARE CONFIGURATION:</A>

<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>

<A NAME="libtiff">CHANGES IN LIBTIFF:</A>

<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.

</UL>

<A NAME="tools">CHANGES IN THE TOOLS:</A>

<UL>

<LI>tiffset: add -d and -sd switches to allow operation on
	a particular directory, not just the first.

<UL>

<li> None

</UL>

<A NAME="configure">CHANGES IN THE SOFTWARE CONFIGURATION:</A>

<UL>

<li> Updated to use Automake 1.15 and Libtool 2.4.5

</UL>

<A NAME="libtiff">CHANGES IN LIBTIFF:</A>

<UL>

<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
 &lt;= 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.

</UL>

<A NAME="tools">CHANGES IN THE TOOLS:</A>

 <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> tiffdump: Guard against arithmetic overflow when calculating allocation buffer sizes.
 <li> tiffdump: fix crash due to overflow of entry count.

<UL>

<li> Support for configure/build using CMake.
	<li> Support for large (> 2GB) files under Microsoft Windows.

</UL>

<A NAME="configure">CHANGES IN THE SOFTWARE CONFIGURATION:</A>

<UL>

<LI> CMakeLists.txt / CMake
 <UL>
 <LI> Configuration and building using CMake is now supported
 under Microsoft Windows and on Unix-type systems.
 </UL>
 </LI>

<LI> configure.ac / configure
 <UL>
 <LI> Test for and use fseeko() if it is available. This allows

 </UL>
 </LI>

</UL>

<A NAME="libtiff">CHANGES IN LIBTIFF:</A>

<UL>

<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.

<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.

 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

 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

 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

 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.

<UL>

<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
 CHUNKY_STRIP_READ_SUPPORT mode with tif_rawdataloaded when
 calling TIFFStartStrip() or TIFFFillStripPartial(). This
 avoids reading beyond tif_rawdata when bytecount >
 tif_rawdatasize. Fixes
 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=1545.

<LI> libtiff/tif_color.c: avoid potential int32 overflow in
 TIFFYCbCrToRGBInit() Fixes
 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=1533
 Credit to OSS-Fuzz

<LI> libtiff/tif_pixarlog.c, tif_luv.c: avoid potential int32
 overflows in multiply_ms() and add_ms(). Fixes
 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=1558
 Credit to OSS-Fuzz

<LI> libtiff/tif_packbits.c: fix out-of-buffer read in
 PackBitsDecode() Fixes
 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=1563
 Credit to OSS-Fuzz

<LI> libtiff/tif_luv.c: LogL16InitState(): avoid excessive memory
 allocation when RowsPerStrip tag is missing.
 Credit to OSS-Fuzz (locally run, on GDAL)

<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> libtiff/tif_getimage.c: initYCbCrConversion(): add basic
 validation of luma and refBlackWhite coefficients (just check
 they are not NaN for now), to avoid potential float to int
 overflows. Fixes
 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=1663
 Credit to OSS Fuzz

<LI> libtiff/tif_read.c: _TIFFVSetField(): fix outside range cast
 of double to float. Credit to Google Autofuzz project

<UL>

<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> nmake.opt: support a DEBUG=1 option, so as to adjust OPTFLAGS and use
	/MDd runtime in debug mode.

<A NAME="libtiff">CHANGES IN LIBTIFF:</A>

<UL>

<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=2580) by Raphaël Hertzog.
	Fixes:

	http://bugzilla.maptools.org/show_bug.cgi?id=2441
	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
	Credit to OSS Fuzz
 <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.
	Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2350

 <LI> 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

 <LI> 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
 <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
	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)
 <LI> 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
 <LI> 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
 <LI> 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
 <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.
 <LI> libtiff/libtiff.def: add TIFFReadRGBAStripExt and TIFFReadRGBATileExt
	Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2735
 <LI> 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
 <LI> libtiff/tif_getimage.c: avoid floating point division by zero in
	initCIELabConversion()

<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> 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.
 <LI> 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.
 <LI> tools/tiff2pdf.c (t2p_sample_realize_palette): Fix possible
	arithmetic overflow in bounds checking code and eliminate
	comparison between signed and unsigned type.
 <LI> 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.

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!

<H1>
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.

<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:

<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> field_tag: the tag number. For instance 277 for the
SamplesPerPixel tag. Builtin tags will generally have a #define in
tiff.h for each known tag.

<li> field_readcount: 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.

<li> field_writecount: 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.

<li> field_type: 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.

<li> field_bit: 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.

<li> field_oktochange: 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).

<li> field_passcount: 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).

<li> field_name: A name for the tag. Normally mixed case (studly caps) 
like "StripByteCounts" and relatively short.

</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.

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.

<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().

When tags are autodefined like this the field_readcount and
field_writecount values are always TIFF_VARIABLE. The 
field_passcount is always TRUE, and the field_bit is 
FIELD_CUSTOM. The field name will be "Tag %d" where the %d is the tag 
number.

<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.

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:

<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.

<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.

<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.

<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.

<A NAME=AddingTags><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.

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 tiff.h.
<LI>Add a field to the directory structure in tif_dir.h
 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
 tif_dirinfo.c. 
 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>(optional) 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 tif_print.c
 to print the tag's value.
</OL>

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><H2>Adding New Codec-private Tags</H2></A>

To add tags that are meaningful only when a particular compression
algorithm is used follow these steps:

<OL>
<LI>Define the tag in tiff.h.
<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 tif_fax3.c
 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+&lt;offset&gt;</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
tiffiop.h.

</ul>
 
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>
% cd ./tiff-4.0.5
% cmake
 ...lots of messages...
% make
 ...lots of messages...
% make test
 ...lots of messages...
# make install
</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.
In general, the software is designed such that the following
targets will always be available
<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>
% gzip -dc tiff-4.0.5.tar.gz | tar -xf -
% cd ./tiff-4.0.5
% cmake
% make
% make test
% make install
</pre></div>
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.
<div style="margin-left: 2em">
<pre>
% gzip -dc tiff-4.0.5.tar.gz | tar -xf -
% mkdir tiff-4.0.5-build
% cd ./tiff-4.0.5-build
% cmake ../tiff-4.0.5
% make
% make test
% make install
</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 cmake --help 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>
cmake -G Ninja
cmake --build .
ctest -V
cmake --build . --target install
</pre>
Note that cmake --build . is a build-system-independent way
of building a target; you can always use the build system directly.
Alternatively, using the MSBuild system on Windows (64-bit Release
build with VS2013):

<pre>
cmake -G "Visual Studio 12 2013 Win64"
cmake --build . --config Release
ctest -V -C Release
cmake --build . --config Release --target install
</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.
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 /usr/local hierarchy. To change
this behaviour the appropriate parameters can be specified on the
command line. Run cmake --help to get a full list of possible
options, and cmake -LH to list all the configurable options for
this software package, or cmake -LAH to show all advanced
options in addition. Standard installation related options are shown
below.
<pre>
<tt>
Installation directories:
 CMAKE_INSTALL_PREFIX

Fine tuning of the installation directories:
 CMAKE_INSTALL_BINDIR user executables [PREFIX/bin]
 CMAKE_INSTALL_SBINDIR system admin executables [PREFIX/sbin]

<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
cmake commandline parameters.
<dl>
<dt>Static/Shared Objects Support</dt>
<dd><tt>BUILD_SHARED_LIBS[=ON|OFF]&nbsp;&nbsp;&nbsp;&nbsp;build shared
libraries [default=ON]</tt> 
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.

<tt>ld-version-script[=ON|OFF]&nbsp;&nbsp;Enable linker version
script (default is ON)</tt>
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.
</dd>
<dt>JPEG Support</dt>
<dd><tt>jpeg[=ON|OFF]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;enable IJG JPEG
library usage (required for JPEG compression, enabled by default) 
JPEG_INCLUDE_DIR=DIR&nbsp;location of IJG
JPEG library headers 
JPEG_LIBRARY=DIR&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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>. cmake
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>ZIP Support</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>
% cd ./tiff-4.0.5
% ./configure
 ...lots of messages...
% make
 ...lots of messages...
% make check
 ...lots of messages...
# make install
</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.
In general, the software is designed such that the following
should be ``make-able'' in each directory:
<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>
% gzip -dc tiff-4.0.5.tar.gz | tar -xf -
% cd ./tiff-4.0.5
% ./configure
% make
% make check
% make install
</pre></div>
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.
<div style="margin-left: 2em">
<pre>
% gzip -dc tiff-4.0.5.tar.gz | tar -xf -
% mkdir tiff-4.0.5-build
% cd ./tiff-4.0.5-build
% ../tiff-4.0.5/configure
% make
% make check
% make install
</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.
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 /usr/local hierarchy. To
change this behaviour the appropriate parameters can be specified
on the command line to configure. Run ./configure --help to
get a full list of possible options. Standard installation related
options are shown below.
<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]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/tiff]
  --htmldir=DIR           html documentation [DOCDIR]

Program names:
 --program-prefix=PREFIX prepend PREFIX to installed program names
 --program-suffix=SUFFIX append SUFFIX to installed program names
 --program-transform-name=PROGRAM run sed PROGRAM on installed program names

<hr width="65%" align="right">
<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
configure script commandline parameters.
<dl>
<dt>Static/Shared Objects Support</dt>
<dd><tt>--enable-shared[=PKGS]&nbsp;&nbsp;&nbsp;&nbsp;build shared
libraries [default=yes] 
--enable-static[=PKGS]&nbsp;&nbsp;&nbsp;&nbsp;build static
libraries [default=yes]</tt>
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.

<tt>--enable-rpath&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Enable
runtime linker paths (-R libtool option)</tt>
Add library directories (see other options below) to the TIFF
library run-time linker path.
<tt>--enable-ld-version-script&nbsp;&nbsp;Enable linker version
script (default is disabled)</tt>
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.
</dd>
<dt>JPEG Support</dt>
<dd><tt>--disable-jpeg&nbsp;&nbsp;&nbsp;&nbsp;disable IJG JPEG
library usage (required for JPEG compression, enabled by default)
--with-jpeg-include-dir=DIR&nbsp;&nbsp;&nbsp;&nbsp;location of IJG
JPEG library headers
--with-jpeg-lib-dir=DIR&nbsp;&nbsp;&nbsp;&nbsp;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>. configure
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>ZIP Support</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>.
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:
<pre>
 unzip -aa -a tiff-4.0.5.zip
</pre>
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
(JPEG_SUPPORT, OJPEG_SUPPORT, PIXARLOG_SUPPORT,
ZIP_SUPPORT), 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.
To build using the provided makefile.vc you may use:
<pre>
 C:\tiff-4.0.5&gt; nmake /f makefile.vc clean
 C:\tiff-4.0.5&gt; nmake /f makefile.vc

or (the hard way)

C:\tiff-4.0.5&gt; cd port
 C:\tiff-4.0.5\port&gt; nmake /f makefile.vc clean
 C:\tiff-4.0.5\port&gt; nmake /f makefile.vc
 C:\tiff-4.0.5&gt; cd ../libtiff
 C:\tiff-4.0.5\libtiff&gt; nmake /f makefile.vc clean
 C:\tiff-4.0.5\libtiff&gt; nmake /f makefile.vc
 C:\tiff-4.0.5\libtiff&gt; cd ..\tools
 C:\tiff-4.0.5\tools&gt; nmake /f makefile.vc clean
 C:\tiff-4.0.5\tools&gt; nmake /f makefile.vc
</pre>
This will build the library
file <tt>libtiff\libtiff\libtiff.lib</tt>.
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.
The <tt>libtiff\tools\makefile.vc</tt> should build .exe's for
all the standard TIFF tool programs.

<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.
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*.
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.
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 libtiff and tools directories.
<h3>Compiling your own program on a VMS system:</h3>
When compiling a source file in which you <tt>"#include
&lt;tiffio.h&gt;"</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 at run time. Using the compilation
procedure above, the tools are linked in this way.
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.

<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
libtiff directory.
The library requires two files that are generated
on-the-fly. The file tif_fax3sm.c 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,
<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.
The second file required to build the library, version.h,
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,
<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>
Otherwise, when building the library on a non-UNIX system be
sure to consult the files tiffcomp.h and tiffconf.h.
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.
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>.
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 port 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 port directory. It may be
necessary to manually do this work on a non-UNIX system. <a name=
"Testing" id="Testing"></a>
<hr>
<h2>Checking out the Software</h2>
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,
<div style="margin-left: 2em">
<pre>
tiffcp -lzw cramps.tif x.tif
tiffcmp cramps.tif x.tif
</pre></div>
(<tt>tiffcmp</tt> should be silent if the files compare
correctly). <a name="TOC" id="TOC"></a>

A copy of the 6.0 specification is available from Adobe at
<A HREF="http://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf">http://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf</A>, or from the libtiff
ftp site at <a href="ftp://download.osgeo.org/libtiff/doc/TIFF6.pdf">
ftp://download.osgeo.org/libtiff/doc/TIFF6.pdf</A>.

Draft <a href="TIFFTechNote2.html">TIFF Technical Note #2</A> covers problems 
with the TIFF 6.0 design for embedding JPEG-compressed data in TIFF, and 
describes an alternative.

TIFF Test Images
</H1>

Test images are available for most formats supported by the library.
Most of the images included in the test kit are also part of this
documentation (albeit in TIFF rather than GIF or JFIF).
The images are kept in a separate archive that should be located in
the same directory as this software.

The latest archive of test images is located at
<A HREF="ftp://download.osgeo.org/libtiff/pics-3.8.0.tar.gz">
ftp://download.osgeo.org/libtiff/pics-3.8.0.tar.gz</A>

There are two other good sources for TIFF test images:
the contributed software contrib/dbs includes several
programs that generate test images suitable for debugging, and
the <TT>tiffcp</TT> program can be used to generate a variety
of images with different storage characteristics.

 This software provides support for the Tag Image File Format (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.
 
 
 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.
 
 
 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.
 
 
 The software was originally authored and maintained by Sam Leffler
 but has been maintained by a cast of others since 1999.
 
 
 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>.

Modifying The TIFF Library
</H1>

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"><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 tiffconf.h.

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>

If the define <TT>COMPRESSION_SUPPORT</TT> is not defined
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>

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>.

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>.

<IMG SRC="images/info.gif" ALT="NOTE: " ALIGN=left HSPACE=8>
Enabling JPEG support automatically enables support for
the TIFF 6.0 colorimetry and YCbCr-related tags.

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>.
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>).

<IMG SRC="images/warning.gif" ALT="NOTE: " ALIGN=left HSPACE=8 VSPACE=6>
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.

By default tiffconf.h defines
<TT>COLORIMETRY_SUPPORT</TT>, 
<TT>YCBCR_SUPPORT</TT>,
and 
<TT>CMYK_SUPPORT</TT>.

<A NAME="Portability"><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.

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.

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>&lt;stdarg.h&gt;</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>&lt;stdarg.h&gt;</TT>, but I am
no longer interested in these
antiquated environments. With the general availability of
the freely available GCC compiler, I
see no reason to incorporate modifications to the software for these
purposes.

An effort has been made to isolate as many of the
operating system-dependencies
as possible in two files: tiffcomp.h and
libtiff/tif_&lt;os&gt;.c. The latter file contains
operating system-specific routines to do I/O and I/O-related operations.
The UNIX (tif_unix.c),
Macintosh (tif_apple.c),
and VMS (tif_vms.c)
code has had the most use;
the MS/DOS support (tif_msdos.c) 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>).

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.

The following defines control general portability:

<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 mmap-style 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>

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 tiffcomp.h defines <TT>HAVE_IEEEFP</TT> to be
1 (<TT>BSDTYPES</TT> is not defined).

<A NAME="Types"><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:

<TR>
<TD>uint8</TD>
<TD>8-bit unsigned integer</TD>
<TD>tiff.h</TD>
</TR>

<TR>
<TD>int8</TD>
<TD>8-bit signed integer</TD>
<TD>tiff.h</TD>
</TR>

<TR>
<TD>uint16</TD>
<TD>16-bit unsigned integer</TD>
<TD>tiff.h</TD>
</TR>

<TR>
<TD>int16</TD>
<TD>16-bit signed integer</TD>
<TD>tiff.h</TD>
</TR>

<TR>
<TD>uint32</TD>
<TD>32-bit unsigned integer</TD>
<TD>tiff.h</TD>
</TR>

<TR>
<TD>int32</TD>
<TD>32-bit signed integer</TD>
<TD>tiff.h</TD>
</TR>

<TR>
<TD>dblparam_t</TD>
<TD>promoted type for floats</TD>
<TD>tiffcomp.h</TD>
</TR>

</TABLE>

(to clarify <TT>dblparam_t</TT>, it is the type that float parameters are
promoted to when passed by value in a function call.)

The following typedefs are used throughout the library and interfaces
to refer to certain objects whose size is dependent on the TIFF image
structure:

<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>

<TR>
<TD>typedef uint16 tsample_t;</TD>	<TD>sample number</TD>
</TR>

<TR>
<TD>typedef uint32 tstrip_t;</TD>	<TD>strip number</TD>
</TR>

<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>

<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>

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.

<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><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 tiff.h.
<LI>Edit the file tif_codec.c to add an entry to the
 _TIFFBuiltinCODECS array (see how other algorithms are handled).
<LI>Add the appropriate function prototype declaration to
 tiffiop.h (close to the bottom).
<LI>Create a file with the compression scheme code, by convention files
 are named tif_*.c (except perhaps on some systems where the
 tif_ prefix pushes some filenames over 14 chars.
<LI>Edit Makefile.in (and any other Makefiles)
 to include the new source file.
</OL>

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 &gt;0 and &lt;rows/strip */
fooCleanup(tif)		/* called when compression scheme is replaced by user */
</PRE>

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.

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 tif_predict.c.

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.

In general, if you have a new compression algorithm to add, work from
the code for an existing routine. In particular,
tif_dumpmode.c
has the trivial code for the "nil" compression scheme,
tif_packbits.c is a
simple byte-oriented scheme that has to watch out for buffer
boundaries, and tif_lzw.c 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
</H1>

The following definitions are used throughout this documentation.
They are consistent with the terminology used in the TIFF 6.0 specification.

<DL>
<DT>Sample
<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>Pixel
<DD>A collection of one or more samples that go together.
<DT>Row
<DD>An Nx1 rectangular collection of pixels.
<DT>Tile
<DD>An NxM rectangular organization of data (or pixels).
<DT>Strip
<DD>A tile whose width is the full image width.
<DT>Compression
<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>Codec
<DD>Software that implements the decoding and encoding algorithms
 of a compression scheme.
</UL>

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>
 
 <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.
 
 </td>
 </tr>
 </table>
 
 
 <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.
 
 
 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.
 
 
 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>
 
 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:
 
 
 <tt>TIFF &lt;version&gt; &lt;alpha&gt;</tt>
 
 
 where <tt>&lt;version&gt;</tt> is whatever you get from
 <tt>"cat VERSION"</tt> and <tt>&lt;alpha&gt;</tt> is
 what you get from <tt>"cat dist/tiff.alpha"</tt>.
 
 
 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>&lt;tiffio.h&gt;</tt> contains a C pre-processor
 define <tt>TIFFLIB_VERSION</tt> that can be used to check library
 version compatiblity at compile time.
 
 <hr>
 <h2 id="typedefs">Library Datatypes</h2>
 
 <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 tiff.h and
 tiffio.h,
 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.
 
 <hr>
 <h2 id="mman">Memory Management</h2>
 
 <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.)
 
 
 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>.
 
 <hr>
 <h2 id="errors">Error Handling</h2>
 
 <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>
 
 <hr>
 <h2 id="fio">Basic File Handling</h2>
 
 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:
 
 
 <tt>#include "tiffio.h" 
 main() 
 { 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("foo.tif", "r"); 
 &nbsp;&nbsp;&nbsp;&nbsp;... do stuff ... 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif); 
 }</tt>
 
 
 The handle returned by <tt>TIFFOpen</tt> is opaque, 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.
 
 
 To create or overwrite a TIFF image the file is also opened, but with
 a <tt>"w"</tt> argument:
 
 
 <tt>#include "tiffio.h" 
 main() 
 { 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("foo.tif", "w"); 
 &nbsp;&nbsp;&nbsp;&nbsp;... do stuff ... 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif); 
 }</tt>
 
 
 If the file already exists it is first truncated to zero length.
 
 <table>
 <tr>
 <td valign=top><img src="images/warning.gif" width="40" height="40" alt=""></td>
 <td>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.</td>
 </tr>
 </table>
 
 <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>.
 
 <hr>
 <h2 id="dirs">TIFF Directories</h2>
 
 TIFF supports the storage of multiple images in a single file.
 Each image has an associated data structure termed a directory
 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.
 
 
 <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).
 
 
 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:
 
 
 <tt>#include "tiffio.h" 
 main(int argc, char* argv[]) 
 { 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen(argv[1], "r"); 
 &nbsp;&nbsp;&nbsp;&nbsp;if (tif) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;int dircount = 0; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;do { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;dircount++; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} while (TIFFReadDirectory(tif)); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;printf("%d directories in %s\n", dircount, argv[1]); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif); 
 &nbsp;&nbsp;&nbsp;&nbsp;} 
 &nbsp;&nbsp;&nbsp;&nbsp;exit(0); 
 }</tt>
 
 
 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.
 
 <hr>
 <h2 id="tags">TIFF Tags</h2>
 
 Image-related information such as the image width and height, number
 of samples, orientation, colorimetric information, etc.
 are stored in each image
 directory in fields or tags.
 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.
 
 
 <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>.
 
 
 <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 get interface 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 set interface takes the tag values either by-reference or
 by-value.
 The TIFF specification defines
 default values 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.
 
 
 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.
 
 <hr>
 <h2 id="compression">TIFF Compression Schemes</h2>
 
 <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.
 
 
 Compression schemes are implemented by software modules termed codecs
 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.
 
 <hr>
 <h2 id="byteorder">Byte Order</h2>
 
 The TIFF specification says, and has always said, that
 a correct TIFF
 reader must handle images in big-endian and little-endian byte order.
 <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).
 
 <hr>
 <h2 id="dataplacement">Data Placement</h2>
 
 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.
 
 <hr>
 <h2 id="tiffrgbaimage">TIFFRGBAImage Support</h2>
 
 <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.
 
 
 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:
 
 
 
 <tt>#include "tiffio.h" 
 main(int argc, char* argv[]) 
 { 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen(argv[1], "r"); 
 &nbsp;&nbsp;&nbsp;&nbsp;if (tif) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 w, h; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;size_t npixels; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32* raster; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &amp;w); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &amp;h); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;npixels = w * h; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;raster = (uint32*) _TIFFmalloc(npixels * sizeof (uint32)); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (raster != NULL) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (TIFFReadRGBAImage(tif, w, h, raster, 0)) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...process raster data... 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_TIFFfree(raster); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif); 
 &nbsp;&nbsp;&nbsp;&nbsp;} 
 &nbsp;&nbsp;&nbsp;&nbsp;exit(0); 
 }</tt>
 
 
 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.
 
 
 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:
 
 
 <tt>#include "tiffio.h" 
 main(int argc, char* argv[]) 
 { 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen(argv[1], "r"); 
 &nbsp;&nbsp;&nbsp;&nbsp;if (tif) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFRGBAImage img; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;char emsg[1024]; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (TIFFRGBAImageBegin(&amp;img, tif, 0, emsg)) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;size_t npixels; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32* raster; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;npixels = img.width * img.height; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;raster = (uint32*) _TIFFmalloc(npixels * sizeof (uint32)); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (raster != NULL) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (TIFFRGBAImageGet(&amp;img, raster, img.width, img.height)) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...process raster data... 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_TIFFfree(raster); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFRGBAImageEnd(&amp;img); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} else 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFError(argv[1], emsg); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif); 
 &nbsp;&nbsp;&nbsp;&nbsp;} 
 &nbsp;&nbsp;&nbsp;&nbsp;exit(0); 
 }</tt>
 
 
 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:
 
 <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>
 
 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.
 
 
 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.
 
 
 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.
 
 
 The TIFF image viewer found in tools/sgigt.c is an example
 of an application that makes use of the <tt>TIFFRGBAImage</tt>
 support.
 
 <hr>
 <h2 id="scanlines">Scanline-based Image I/O</h2>
 
 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).
 
 
 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:
 
 
 <tt>#include "tiffio.h" 
 main() 
 { 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r"); 
 &nbsp;&nbsp;&nbsp;&nbsp;if (tif) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 imagelength; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 row; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (row = 0; row &lt; imagelength; row++) 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadscanline(tif, buf, row); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif); 
 &nbsp;&nbsp;&nbsp;&nbsp;} 
 }</tt>
 
 
 <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:
 
 
 <tt>#include "tiffio.h" 
 main() 
 { 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r"); 
 &nbsp;&nbsp;&nbsp;&nbsp;if (tif) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 imagelength; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 row; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &amp;imagelength); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_PLANARCONFIG, &amp;config); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(TIFFScanlineSize(tif)); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (config == PLANARCONFIG_CONTIG) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (row = 0; row &lt; imagelength; row++) 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadscanline(tif, buf, row); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} else if (config == planarconfig_separate) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint16 s, nsamples; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffgetfield(tif, tifftag_samplesperpixel, &amp;nsamples); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (s = 0; s &lt; nsamples; s++) 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (row = 0; row &lt; imagelength; row++) 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadscanline(tif, buf, row, s); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif); 
 &nbsp;&nbsp;&nbsp;&nbsp;} 
 }</tt>
 
 
 Beware however that if the following code were used instead to
 read data in the case <tt>PLANARCONFIG_SEPARATE</tt>,...
 
 
 <tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (row = 0; row &lt; imagelength; row++) 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (s = 0; s &lt; nsamples; s++) 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadscanline(tif, buf, row, s);</tt>
 
 
 ...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).
 
 <hr>
 <h2 id="strips">Strip-oriented Image I/O</h2>
 
 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.
 
 
 A simple example of reading an image by strips is:
 
 
 <tt>#include "tiffio.h" 
 main() 
 { 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r"); 
 &nbsp;&nbsp;&nbsp;&nbsp;if (tif) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tstrip_t strip; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(TIFFStripSize(tif)); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (strip = 0; strip &lt; tiffnumberofstrips(tif); strip++) 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadencodedstrip(tif, strip, buf, (tsize_t) -1); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif); 
 &nbsp;&nbsp;&nbsp;&nbsp;} 
 }</tt>
 
 
 Notice how a strip size of <tt>-1</tt> is used; <tt>TIFFReadEncodedStrip</tt>
 will calculate the appropriate size in this case.
 
 
 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.
 
 
 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.
 
 
 The following is an example of how to read raw strips of data from
 a file:
 
 
 <tt>#include "tiffio.h" 
 main() 
 { 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r"); 
 &nbsp;&nbsp;&nbsp;&nbsp;if (tif) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tstrip_t strip; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32* bc; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 stripsize; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_STRIPBYTECOUNTS, &amp;bc); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;stripsize = bc[0]; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(stripsize); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (strip = 0; strip &lt; tiffnumberofstrips(tif); strip++) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (bc[strip] &gt; stripsize) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFrealloc(buf, bc[strip]); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;stripsize = bc[strip]; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFReadRawStrip(tif, strip, buf, bc[strip]); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_TIFFfree(buf); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFClose(tif); 
 &nbsp;&nbsp;&nbsp;&nbsp;} 
 }</tt>
 
 
 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.
 
 <hr>
 <h2 id="tiles">Tile-oriented Image I/O</h2>
 
 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.
 
 
 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.
 
 
 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:
 
 
 <tt>main() 
 { 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r"); 
 &nbsp;&nbsp;&nbsp;&nbsp;if (tif) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 imageWidth, imageLength; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 tileWidth, tileLength; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;uint32 x, y; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &amp;imageWidth); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &amp;imageLength); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_TILEWIDTH, &amp;tileWidth); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TIFFGetField(tif, TIFFTAG_TILELENGTH, &amp;tileLength); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(TIFFTileSize(tif)); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (y = 0; y &lt; imagelength; y += tilelength) 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (x = 0; x &lt; imagewidth; x += tilewidth) 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadtile(tif, buf, x, y, 0); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif); 
 &nbsp;&nbsp;&nbsp;&nbsp;} 
 }</tt>
 
 
 (once again, we assume samples are packed contiguously.)
 
 
 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:
 
 
 <tt>#include "tiffio.h" 
 main() 
 { 
 &nbsp;&nbsp;&nbsp;&nbsp;TIFF* tif = TIFFOpen("myfile.tif", "r"); 
 &nbsp;&nbsp;&nbsp;&nbsp;if (tif) { 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tdata_t buf; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ttile_t tile; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;buf = _TIFFmalloc(TIFFTileSize(tif)); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (tile = 0; tile &lt; tiffnumberoftiles(tif); tile++) 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffreadencodedtile(tif, tile, buf, (tsize_t) -1); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;_tifffree(buf); 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tiffclose(tif); 
 &nbsp;&nbsp;&nbsp;&nbsp;} 
 }</tt>

Silicon Graphics has seen fit to allow us to give this work away. It
is free. There is no support or guarantee of any sort as to its

The libtiff software was written by Sam Leffler while working for
Silicon Graphics.

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:

 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 &amp; Duff's paper in the '84 SIGGRAPH proceedings: "Compositing Digital
 Images".
 
 
 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.
 
 
 The Colorimetry, and CMYK tags are additions that appear in TIFF 6.0.
 Consult the TIFF 6.0 specification included in the doc directory
 and <a href="document.html">online</a>.
 
 
 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</h1>
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.
<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>&nbsp;&nbsp;&nbsp;&nbsp;</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>

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>

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>

</tr>
<tr>
<td valign="top" width="10%"><tt><a href="man/tiffcmp.1.html">tiffcmp</a></tt></td>
<td>Compare the contents of two TIFF files (it does not check all
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>

(it's very useful for debugging bogus files that you may get from
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>

</tr>
<tr>

multi-image file</td>
</tr>

<A NAME="configure">CHANGES IN THE SOFTWARE CONFIGURATION:</A>

<UL>
<LI>It is now possible to setup the software to build only the
 library; configure reconizes this is the intent when the
 VERSION, tiff.alpha, and tif_version.c
 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 port.h file generated by configure is now used only by
 the library and as such as have been moved to the libtiff
 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 dist 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>

<A NAME="libtiff">CHANGES IN LIBTIFF:</A>

<UL>
<LI>two new typedefs were added to tiff.h</TT>: <TT>int8</TT>
 and <TT>uint8</TT> for signed and unsigned 8-bit quantities,
 respectively; these are currently used only by
 programs in the tools directory
<LI>the <TT>BadFaxLines</TT>, <TT>CleanFaxData</TT>, and
 <TT>ConsecutiveBadFaxLines tags are now supported with
 Group 4 compression
<LI>byte order is now correctly identified on 64-bit machines
<LI>a bug was fixed in the PackBits decoder where input data would
 appear short when a no-op run was present
<LI>a bug was fixed in calculations with very wide strips
<LI><TT>TIFFWriteEncodedStrip</TT> and <TT>TIFFWriteRawStrip</TT>
 were extended to support dynamically growing the number of
 strips in an image (must set <TT>ImageLength</TT> prior to
 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 version.h is now built by a new mkversion
 program; this was done for portability to non-UNIX systems
<LI>support was added for the Acorn RISC OS (from Peter Greenham)
<LI>the builtin codec table is now made <TT>const</TT> when compiling
 under VMS so that libtiff can be built as a shared library
<LI>support for the PowerPC Mac (from Ruedi Boesch)
<LI>support for Window NT/Window 95 (from Scott Wagner)
</UL>

<A NAME="tools">CHANGES IN THE TOOLS:</A>

<UL>
<LI>the tools no longer include port.h
<LI>various portability fixes; mostly to eliminate implicit assumptions
 about how long <TT>int32</TT> data types are
<LI>PostScript Level II additions to <TT>tiff2ps</TT> from Bjorn Brox
<LI><TT>sgi2tiff</TT> now handles RGBA images
</UL>

<UL>
<LI>the documentation has been updated to reflect the current state of
 the software
<LI>some routines have been moved to different manual pages
 to group like-routines together
</UL>

<A NAME="contrib">CHANGES IN THE CONTRIBUTED SOFTWARE:</A>

<UL>
<LI>support was added for the Acorn RISC OS (from Peter Greenham)
<LI>support for Windows NT/Windows 95 contributed for a previous
 version of this software was sort of incorporated (it's broken
 right now) (from Scott Wagner)

<A NAME="configure">CHANGES IN THE SOFTWARE CONFIGURATION:</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>&lt;mly@adoc.xerox.com&gt;</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
<LI>a bug was fixed in libtiff/Makefile.in that caused installation
 to fail on systems without DSO support
</UL>

<A NAME="libtiff">CHANGES IN LIBTIFF:</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 tiffiop.h has
 been replaced by <TT>__WIN32__</TT>
</UL>

<A NAME="tools">CHANGES IN THE TOOLS:</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 for Big-Endian byte order, -L
 for Little-Endian byte order; a -M option to disable the
 use of memory-mapped files, and a -C option to disable the
 use of strip chopping
<LI>bugs were fixed in <TT>tiffcp</TT>'s handling of codec-specific tags
</UL>

<A NAME="configure">CHANGES IN THE SOFTWARE CONFIGURATION:</A>

<UL>
<LI>configure now captures significantly more information
 in the config.log 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 /usr/include
 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>
</UL>

<A NAME="libtiff">CHANGES IN LIBTIFF:</A>

<UL>
<LI>the Deflate support has been revised: it requires version 0.99 of
 the zlib software distribution, the output format has changed and
 is incompatible with previous versions of this library (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
 library version
</UL>

<A NAME="man">CHANGES IN THE MANUAL PAGES:</A>

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

* 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/tiffiop.h: First cut at supporting large files under
	Microsoft Windows using tif_unix.c and the libtiff tools.  This
	only works if the Windows CDK is new enough to support the APIs
	used (Visual C++ 2005 or later).  Support for large files is not
	actually tested yet.

* libtiff/tif_config.vc.h: Make adjustments to match the new
	definitions that configure produces, including for WIN64.  Still
	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.

* libtiff/libtiff.def: Added exports for TIFFGetConfiguredCODECs,
	TIFFReadRGBAImageOriented, TIFFSetCompressionScheme,
	TIFFSwabArrayOfTriples, TIFFVGetFieldDefaulted, _TIFFCheckRealloc,
	TIFFRasterScanline, TIFFSetErrorHandlerExt,
	TIFFSetWarningHandlerExt, TIFFNumberOfDirectories,
	TIFFCreateCustomDirectory, TIFFCreateEXIFDirectory,
	TIFFWriteCustomDirectory, _TIFFRewriteField as recommended by
	Roger Leigh and justified by use in libtiff tests, documentation,
	and changelog notes.  Also sorted symbol list and removed
	duplicate entries.

* 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.

	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.

* 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>

	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.

	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>

* 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

	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
	http://bugzilla.maptools.org/show_bug.cgi?id=2207

* tools/{tiff2bw.c, thumbnail.c, pal2rgb.c}: Fix the count for
	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>

* tools/tiffgt.c: Properly check the raster buffer allocations for
	integer overflows. As per bug
	http://bugzilla.maptools.org/show_bug.cgi?id=2108

* m4/acinclude.m4: Update GL/GLU/GLUt/Pthread macros from the
	upstream.

* libtiff/{tif_aux.c, tif_strip.c, tif_tile.c, tiffiop.h}: Move
	multiply_32() and multiply_64() functions into tif_aux.c file and
	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>

	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>

* libtiff/tif_ojpeg.c (OJPEGWriteHeaderInfo): IJG JPEG 7 needs
	do_fancy_upsampling=FALSE in order to read raw data.  Resolves
	"Bug 2090 - OJPEG crash with libjpeg v7".
	http://bugzilla.maptools.org/show_bug.cgi?id=2090

	utilities tests.

2009-08-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

* tools/tiffinfo.c: tiffinfo should return error status to the
	caller.  Register a private error callback to accomplish that.

* test/Makefile.am (TIFFIMAGES): Add test images in BMP, GIF, and

	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)

	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.

	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>

* tools/tiff2pdf.c: Fix problem with alpha setting in some cases
	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
	SetFilePointerEx, as per bug

	_TIFFUInt64ToDouble() functions.

2007-07-18 Andrey Kiselev <dron@ak4719.spb.edu>

* libtiff/tif_dirread.c: Handle the case of MSVC 6 when using 64-bit

	use standard C++ library size types and attempt to detect overflow
	cases.

2007-07-08 Andrey Kiselev <dron@ak4719.spb.edu>

* libtiff/{tif_jpeg.c, tif_dir.h, tif_dir.c, tif_dirinfo.c, tiffio.h,
	tif_ojpeg.c, tif_print.c, tif_fax3.c, tif_dirread.c}: More work on new
	tag extending scheme. Use the new scheme everywhere.

* libtiff/{tif_zip.c, tif_predict.c, tif_pixarlog.c, tif_luv.c,

	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.

2007-06-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

* port/strtoull.c: New porting function in case strtoull() is not
	available on the target system.
	* configure.ac: Add configure support for determining sized types
	in a portable way and performing necessary substitutions in
	tif_config.h and tiffconf.h.  Updated tiff.h to use the new
	definitions.

2007-04-27 Andrey Kiselev <dron@ak4719.spb.edu>

* tools/tiff2pdf.c: Check the tmpfile() return status as per bug

http://bugzilla.remotesensing.org/show_bug.cgi?id=154

2007-04-07 Andrey Kiselev <dron@ak4719.spb.edu>

* libtiff/{tif_dir.h, tif_dirread.c, tif_dirinfo.c, tif_jpeg.c,
	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

	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.

2001-03-29 Frank Warmerdam <warmerdam@pobox.com>

* 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/tiffio.h: Changed "#if LOGLUV_PUBLIC" to
	"#ifdef LOGLUV_PUBLIC" so it will work with VisualAge on AIX.

http://bugzilla.remotesensing.org/show_bug.cgi?id=39

2001-03-16 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>

	  not supported by default.

2000-12-22 Frank Warmerdam <warmerdam@pobox.com>

* updated html/libtiff.html to not point at Niles' old JPL web site
	for the man pages, point at www.libtiff.org.

2000-12-21 Frank Warmerdam <warmerdam@pobox.com>

* libtiff/tif_apple.c: Applied "Carbon" support patches supplied by
	Leonard Rosenthol <leonardr@lazerware.com>. May interfere

	Example file at: ftp://ftp.remotesensing.org/pub/libtiff/eofb_396.tif

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
	I have updated the win32 detection rules in tiffcomp.h.

	See http://bugzilla.remotesensing.org/show_bug.cgi?id=20
	Some patches from Rick LaMont of Dot C Software.

* 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>

* 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.

* 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

2000-10-12 Frank Warmerdam <warmerda@cs46980-c>

* Modified tiff2bw to ensure portions add to 100%, and that

See bug http://bugzilla.remotesensing.org/show_bug.cgi?id=15
	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>

* Added GNULDdso target an`d switched linux and freebsd to use it.

	of EXPAND1D() as per bug 11 (from Roman).

2000-09-25 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

* 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.

2000-09-18 Frank Warmerdam <warmerda@cs46980-c>

* tif_flush.c: Changed so that TIFFFlushData() doesn't return an
	error when TIFF_BEENWRITING is not set.  This ensures that the
	directory contents can still be flushed by TIFFFlush().

2000-08-14 Frank Warmerdam <warmerda@rommel.atlsci.com>

* tif_open.c: Don't set MMAP for O_RDWR files.

* 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.

	the strips per separation fix done a few weeks ago.

2000-07-17 Frank Warmerdam <warmerda@cs46980-c>

	rows for strips that are the last strip in a separation but
	not the last strip of all in TIFFReadEncodedStrip().

* Applied 16/32 bit fix to tif_fax3.c. Fix supplied by
	Peter Skarpetis <peters@serendipity-software.com.au>

2000-06-15 Frank Warmerdam <warmerda@rommel.atlsci.com>
