2020-10-16  Even Rouault  <even.rouault@spatialys.com>

	Add support for optional building against libdeflate for faster Zip/Deflate compression/decompression.
	So we can have 2 kind of builds with the Zip/Deflate codec:
	- zlib only
	- zlib + libdeflate

	Speed improvements in the 35%-50% range can be expected when libdeflate is used.
	Compression level up to 12 is now supported (capped to 9 when zlib is used).
	Still requires zlib for situations where libdeflate cannot be used (that
	is for scanline access, since libdeflate has no streaming mode)

	Pseudo-tag TIFFTAG_DEFLATE_SUBCODEC=DEFLATE_SUBCODEC_ZLIB/DEFLATE_SUBCODEC_LIBDEFLATE
	is added to control which subcodec (zlib or libdeflate) should be used (it defaults
	of course to libdeflate, when it is available).
	This is mostly aimed at being used on the writing side, to be able to reproduce
	output of previous libtiff versions at a binary level, in situations where this would
	be really needed. Or as a safety belt in case there would be unforeseen issues
	with using libdeflate.
	It can be used to know when libdeflate is available at runtime (DEFLATE_SUBCODEC_LIBDEFLATE
	will be the default value in that situation).

	Of course, deflate codestreams produced by libdeflate can be read by zlib, and vice-versa.

	Make pointers returned via TIFFGetField const.
	According to http://bugzilla.maptools.org/show_bug.cgi?id=2125#c6
	callers are not allowed to modify pointer or array values returned from
	TIFFGetField or the like. So, make this explicit in the documentation
	by specifying these things as const. Note that this is not an ABI
	change, since C does not encode const in libraries. Also, this is
	not really an API change, since the varargs call strips away all
	the types anyway. So it really is more of a documentation change.

	Rational with Double Precision Upgrade

	See merge request libtiff/libtiff!100

2020-02-27  Su_Laus  <sulau@freenet.de>

	Rational with Double Precision Upgrade.
	Unfortunately, custom rational tags (TIFF_RATIONAL with field_bit=FIELD_CUSTOM) are defined as TIFF_SETGET_DOUBLE
	but for the reading interface and LibTiff internally they are stored ALWAYS as floating point SINGLE precision.
	Double precision custom rational tags are not supported by LibTiff.

	For the GPS tags in WGS84 a higher accuracy / precision is needed.
	Therefore, this upgrade is made, keeping the old interface for the already defined tags and allowing a double precision definition,
	as well as calculating rationals with higher accuracy / precision.
	This higher accuracy can be used for newly defined tags like that in EXIF/GPS.

	Refer also to the very old Bugzilla issue 2542 (#69)

	A test file rational_precision2double.c is added, which shows prevention of the old interface to the already defined custom rational tags
	with the standard library as well as with the upgraded library.

	Also TIFFTAG_XRESOLUTION, TIFFTAG_YRESOLUTION, TIFFTAG_XPOSITION, TIFFTAG_YPOSITION amended from TIFF_SETGET_DOUBLE to TIFF_SETGET_FLOAT and testcase inserted in rational_precision2double.c

	Simplify nmake configuration for building port directory.  Now there is only one boolean setting to enable building strtoll() and strtoull() port functions.  The boolean setting enables the necessary port files to be built, but the remainder of the logic is via pre-processor code in the common tif_config.h, which was prepared before entering the port directory to do a build.

2020-01-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	Make sure that tif_config.h is produced prior to entering the port directory and add an include path so that the port files can include tif_config.h.  Do not actually include tif_config.h at this time since CMake and Autotools builds are not prepared for that.  This issue could be handled by updating the CMake and Autotools builds or by adding a define which directs libport.h to include tif_config.h.

2020-01-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	nmake.opt:

	  Provide defaults suitable for MSVC prior to 14.0.

	libport.h:

	  The sense of the pre-processor logic was inverted from what it
	  should be.  The intention is to only provide the prototype if the
	  function is missing.

2020-01-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

2019-08-13  Even Rouault  <even.rouault@spatialys.com>

	Fix integer overflow in _TIFFCheckMalloc() and other implementation-defined behaviour (CVE-2019-14973)
	_TIFFCheckMalloc()/_TIFFCheckRealloc() used a unsafe way to detect overflow
	in the multiplication of nmemb and elem_size (which are of type tmsize_t, thus
	signed), which was especially easily triggered on 32-bit builds (with recent
	enough compilers that assume that signed multiplication cannot overflow, since
	this is undefined behaviour by the C standard). The original issue which lead to
	this fix was triggered from tif_fax3.c

	There were also unsafe (implementation defied), and broken in practice on 64bit
	builds, ways of checking that a uint64 fits of a (signed) tmsize_t by doing
	(uint64)(tmsize_t)uint64_var != uint64_var comparisons. Those have no known
	at that time exploits, but are better to fix in a more bullet-proof way.
	Or similarly use of (int64)uint64_var <= 0.

2019-08-04  Su Laus  <sulau@freenet.de>

	Reading of Tiff tags with ID = 0 (like GPSVERSIONID) corrected.
	  IGNORE placeholder in tif_dirread.c is now replaced by a field dir_ignore in the TIFFDirEntry structure

	  Currently, in tif_dirread.c a special IGNORE value for the tif tags is defined
	  in order to flag status preventing already processed tags from further processing.
	  This irrational behaviour prevents reading of custom tags with id code 0 - like tag GPSVERSIONID from EXIF 2.31 definition.

	  An additional field 'tdir_ignore' is now added to the TIFFDirEntry structure and code is changed
	  to allow tags with id code 0 to be read correctly.

	  This change was already proposed as pending improvement in tif_dirread.c around line 32.

	Add TIFFDeferStrileArrayWriting() and TIFFForceStrileArrayWriting()
	Those advanced writing functions must be used in a particular sequence
	to make their intended effect. Their aim is to control when/where
	the [Strip/Tile][Offsets/ByteCounts] arrays are written into the file.

	The purpose of this is to generate 'cloud-optimized geotiff' files where
	the first KB of the file only contain the IFD entries without the potentially
	large strile arrays. Those are written afterwards.

	The typical sequence of calls is:
	TIFFOpen()
	[ TIFFCreateDirectory(tif) ]
	Set fields with calls to TIFFSetField(tif, ...)
	TIFFDeferStrileArrayWriting(tif)
	TIFFWriteCheck(tif, ...)
	 TIFFWriteDirectory(tif)
	 ... potentially create other directories and come back to the above directory
	TIFFForceStrileArrayWriting(tif): emit the arrays at the end of file

	See test/defer_strile_writing.c for a practical example.

	Make defer strile offset/bytecount loading available at runtime.
	... and add per-strile offset/bytecount loading capabilities.

	Part of this commit makes the behaviour that was previously met when
	libtiff was compiled with -DDEFER_STRILE_LOAD available for default builds
	when specifying the new 'D' (Deferred) TIFFOpen() flag. In that mode, the [Tile/Strip][ByteCounts/Offsets]
	arrays are only loaded when first accessed. This can speed-up the opening
	of files stored on the network when just metadata retrieval is needed.
	This mode has been used for years by the GDAL library when compiled with
	its embedded libtiff copy.

	To avoid potential out-of-tree code (typically codecs) that would use
	the td_stripbytecount and td_stripoffset array inconditionnaly assuming they
	have been loaded, those have been suffixed with _p (for protected). The
	use of the new functions mentioned below is then recommended.

	Another addition of this commit is the capability of loading only the
	values of the offset/bytecount of the strile of interest instead of the
	whole array. This is enabled with the new 'O' (Ondemand) flag of TIFFOpen()
	(which implies 'D'). That behaviour has also been used by GDAL, which hacked
	into the td_stripoffset/td_stripbytecount arrays directly. The new code
	added in the _TIFFFetchStrileValue() and _TIFFPartialReadStripArray() internal
	functions is mostly a port of what was in GDAL GTiff driver previously.

	Related to that, the public TIFFGetStrileOffset[WithErr]() and TIFFGetStrileByteCount[WithErr]()
	functions have been added to API. They are of particular interest when
	using sparse files (with offset == bytecount == 0) and you want to detect
	if a strile is present or not without decompressing the data, or updating
	an existing sparse file.
	They will also be used to enable a future enhancement where client code can entirely
	skip bytecount loading in some situations

	A new test/defer_strile_loading.c test has been added to test the above
	capabilities.

2019-05-10  Even Rouault  <even.rouault@spatialys.com>

	Creation: use SHORT type when possible for StripByteCounts/TileByteCounts
	This follows the same logic as previous commit.

2019-05-09  Even Rouault  <even.rouault@spatialys.com>

	BigTIFF creation: write TileByteCounts/StripByteCounts tag with LONG when possible
	In most situations of BigTIFF file, the tile/strip sizes are of reasonable size,
	that is they fit on a 4-byte LONG. So in that case, use LONG instead of LONG8
	to save some space. For uncompressed file, it is easy to detect such situations
	by checking at the TIFFTileSize64()/TIFFStripSize64() return. For compressed file,
	we must take into account the fact that compression may sometimes result in
	larger compressed data. So we allow this optimization only for a few select
	compression times, and take a huge security margin (10x factor). We also only
	apply this optimization on multi-strip files, so as to allow easy on-the-fly
	growing of single-strip files whose strip size could grow above the 4GB threshold.

	This change is compatible with the BigTIFF specification. According to
	https://www.awaresystems.be/imaging/tiff/bigtiff.html:
	"The StripOffsets, StripByteCounts, TileOffsets, and TileByteCounts tags are
	allowed to have the datatype TIFF_LONG8 in BigTIFF. Old datatypes TIFF_LONG,
	and TIFF_SHORT where allowed in the TIFF 6.0 specification, are still valid in BigTIFF, too. "
	On a practical point of view, this is also compatible on reading/writing of
	older libtiff 4.X versions.

	The only glitch I found, which is rather minor, is when using such a BigTIFF
	file with TileByteCounts/StripByteCounts written with TIFF_LONG, and updating
	it with an older libtiff 4.X version with a change in the
	[Tile/Strip][ByteCounts/Offsets] array. In that case the _TIFFRewriteField()
	function will rewrite the directory and array with TIFF_LONG8, instead of updating
	the existing array (this is an issue fixed by this commit). The file will
	still be valid however, hence the minor severity of this.

	tif_dir: unset transferfunction field if necessary.
	The number of entries in the transfer table is determined as following:

	This means that whenever td->td_samplesperpixel or td->td_extrasamples are
	modified we also need to make sure that the number of required entries in
	the transfer table didn't change.

	If it changed and the number of entries is higher than before we should
	invalidate the transfer table field and free previously allocated values.
	In the other case there's nothing to do, additional tf entries won't harm
	and properly written code will just ignore them since spp - es < 1.

	For instance this situation might happen when reading an OJPEG compressed
	image with missing SamplesPerPixel tag. In this case the SamplesPerPixel
	field might be updated after setting the transfer table.

	Fix NULL pointer dereference in TIFFPrintDirectory (bugzilla 2778/CVE-2018-7456)

	See merge request libtiff/libtiff!27

2018-04-11  Hugo Lefeuvre  <hle@debian.org>

	Fix NULL pointer dereference in TIFFPrintDirectory.
	The TIFFPrintDirectory function relies on the following assumptions,
	supposed to be guaranteed by the specification:

	(a) A Transfer Function field is only present if the TIFF file has
	    photometric type < 3.

	(b) If SamplesPerPixel > Color Channels, then the ExtraSamples field
	    has count SamplesPerPixel - (Color Channels) and contains
	    information about supplementary channels.

	While respect of (a) and (b) are essential for the well functioning of
	TIFFPrintDirectory, no checks are realized neither by the callee nor
	by TIFFPrintDirectory itself. Hence, following scenarios might happen
	and trigger the NULL pointer dereference:

	(1) TIFF File of photometric type 4 or more has illegal Transfer
	    Function field.

	(2) TIFF File has photometric type 3 or less and defines a
	    SamplesPerPixel field such that SamplesPerPixel > Color Channels
	    without defining all extra samples in the ExtraSamples fields.

	In this patch, we address both issues with respect of the following
	principles:

	(A) In the case of (1), the defined transfer table should be printed
	    safely even if it isn't 'legal'. This allows us to avoid expensive
	    checks in TIFFPrintDirectory. Also, it is quite possible that
	    an alternative photometric type would be developed (not part of the
	    standard) and would allow definition of Transfer Table. We want
	    libtiff to be able to handle this scenario out of the box.

	(B) In the case of (2), the transfer table should be printed at its
	    right size, that is if TIFF file has photometric type Palette
	    then the transfer table should have one row and not three, even
	    if two extra samples are declared.

	In order to fulfill (A) we simply add a new 'i < 3' end condition to
	the broken TIFFPrintDirectory loop. This makes sure that in any case
	where (b) would be respected but not (a), everything stays fine.

	(B) is fulfilled by the loop condition
	'i < td->td_samplesperpixel - td->td_extrasamples'. This is enough as
	long as (b) is respected.

	Naturally, we also make sure (b) is respected. This is done in the
	TIFFReadDirectory function by making sure any non-color channel is
	counted in ExtraSamples.

	This commit addresses CVE-2018-7456.

	Fix for bug 2772.
	It is possible to craft a TIFF document where the IFD list is circular,
	leading to an infinite loop while traversing the chain. The libtiff
	directory reader has a failsafe that will break out of this loop after
	reading 65535 directory entries, but it will continue processing,
	consuming time and resources to process what is essentially a bogus TIFF
	document.

	This change fixes the above behavior by breaking out of processing when
	a TIFF document has >= 65535 directories and terminating with an error.

	Add ZSTD compression codec.
	From https://github.com/facebook/zstd
	"Zstandard, or zstd as short version, is a fast lossless compression
	algorithm, targeting real-time compression scenarios at zlib-level
	and better compression ratios. It's backed by a very fast entropy stage,
	provided by Huff0 and FSE library."

	We require libzstd >= 1.0.0 so as to be able to use streaming compression
	and decompression methods.

	The default compression level we have selected is 9 (range goes from 1 to 22),
	which experimentally offers equivalent or better compression ratio than
	the default deflate/ZIP level of 6, and much faster compression.

	For example on a 6600x4400 16bit image, tiffcp -c zip runs in 10.7 seconds,
	while tiffcp -c zstd runs in 5.3 seconds. Decompression time for zip is
	840 ms, and for zstd 650 ms. File size is 42735936 for zip, and
	42586822 for zstd. Similar findings on other images.

	tiff2pdf: Fix apparent incorrect type for transfer table.

2017-12-10  Brian May  <brian@linuxpenguins.xyz>

	tiff2pdf: Fix CVE-2017-9935.
	Fix for http://bugzilla.maptools.org/show_bug.cgi?id=2704

	This vulnerability - at least for the supplied test case - is because we
	assume that a tiff will only have one transfer function that is the same
	for all pages. This is not required by the TIFF standards.

	We than read the transfer function for every page.  Depending on the
	transfer function, we allocate either 2 or 4 bytes to the XREF buffer.
	We allocate this memory after we read in the transfer function for the
	page.

	For the first exploit - POC1, this file has 3 pages. For the first page
	we allocate 2 extra extra XREF entries. Then for the next page 2 more
	entries. Then for the last page the transfer function changes and we
	allocate 4 more entries.

	When we read the file into memory, we assume we have 4 bytes extra for
	each and every page (as per the last transfer function we read). Which
	is not correct, we only have 2 bytes extra for the first 2 pages. As a
	result, we end up writing past the end of the buffer.

	There are also some related issues that this also fixes. For example,
	TIFFGetField can return uninitialized pointer values, and the logic to
	detect a N=3 vs N=1 transfer function seemed rather strange.

	It is also strange that we declare the transfer functions to be of type
	float, when the standard says they are unsigned 16 bit values. This is
	fixed in another patch.

	This patch will check to ensure that the N value for every transfer
	function is the same for every page. If this changes, we abort with an
	error. In theory, we should perhaps check that the transfer function
	itself is identical for every page, however we don't do that due to the
	confusion of the type of the data in the transfer function.

	* tools/tiffcrop.c: fix various out-of-bounds write vulnerabilities
	in heap or stack allocated buffers. Reported as MSVR 35093,
	MSVR 35096 and MSVR 35097. Discovered by Axel Souchet and Vishal
	Chauhan from the MSRC Vulnerabilities & Mitigations team.
	* tools/tiff2pdf.c: fix out-of-bounds write vulnerabilities in
	heap allocate buffer in t2p_process_jpeg_strip(). Reported as MSVR
	35098. Discovered by Axel Souchet and Vishal Chauhan from the MSRC
	Vulnerabilities & Mitigations team.
	* 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.
	* 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.

	with BSD make and to make use of cmake in 'distcheck' target
	conditional on if cmake is available.

	* CMakeLists.txt, Makefile.am, configure.ac: Applied patches by
	Roger Leigh (via tiff mailing list on 2015-09-01).

	CMake build is now included in 'distcheck' target.

	Builds with CMake 2.8.9 and newer.

	Tar is now resquested to use POSIX PAX format.

2015-08-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* 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).

2015-08-31  Even Rouault <even.rouault at spatialys.com>

	* libtiff/tif_predict.c: pedantic change to add explicit masking
	with 0xff before casting to uchar in floating-point horizontal
	differencing and accumulation routines.

2015-08-31  Even Rouault <even.rouault at spatialys.com>

	* libtiff/tif_predict.c: fix generation of output with 16 bit
	or 32 bit integer, when byte swapping is needed, in
	horizontal predictor (#2521). Also fixes decoding when there is
	a single pixel to code (unlikely case...) and byte swapping is
	involved.

2015-08-30  Even Rouault <even.rouault at spatialys.com>

	* libtiff/tif_lzw.c: make nextdata a unsigned type to avoid
	undefined behaviour with shifts (gcc -fsanitize=shift)

	to match autoconf.  Note: defaults to 'on' to be ABI-compatible by
	default with common Linux distribution builds.  Note that the
	autoconf configure script defaults to 'off'.

2015-08-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/tiffiop.h: For MinGW comiles, make sure that build
	supports necessary __MSVCRT_VERSION__ (at least at least 0x800).
	Otherwise large files can not be supported for POSIX-style I/O.

	* tools/fax2tiff.c (main): Eliminate a compiler warning in 64-bit
	builds about cast to thandle_t.

	* test/rewrite_tag.c (main): Does not require any arguments.

2015-08-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	changes.

2015-08-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* 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.

2015-08-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/tif_jpeg.c: Applied patch by Räisä Olli to assure that

	* CMakeLists.txt: Add CMake patchset by Roger Leigh as posted to
	libtiff mailing list on Mon, 22 Jun 2015 21:21:01 +0100. Several
	corrections to ensure that the autotools build still works were
	added by me.  I have not yet tested the build using 'cmake' or
	MSVC with 'nmake'.

2015-06-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* test/Makefile.am: tiff2rgba-quad-tile.jpg.sh depends on the JPEG
	library so only execute if JPEG is available.

	* libtiff 4.0.4 released.

	* configure.ac: Add a HAVE_FOO Automake conditional for each
	add-on library.

	* test/Makefile.am (JPEG_DEPENDENT_CHECK_PROG): raw_decode
	requires JPEG support to compile.  Use Automake conditional to
	only include it when JPEG support is available.

	* html/build.html: Try to improve the nmake-based VC++ build
	description.

	* libtiff/tiffconf.vc.h: Build fixes based on testing.

	* libtiff/tif_config.vc.h: Build fixes based on testing.

	* libtiff/libtiff.def: TIFFRasterScanline does not exist so remove
	export for it.

2015-06-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* 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 interpreted 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.

 	deprecate use of sprintf().

2013-03-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Applied patch by Brad Smith to improve pkg-config
	static linking by adding -lm to Libs.private when needed.

2013-03-05  Tom Lane  <tgl@sss.pgh.pa.us>

	* html/man/tiff2ps.1.html, html/man/tiffcp.1.html,
 	html/man/tiffdither.1.html, man/tiff2ps.1, man/tiffcp.1,
 	man/tiffdither.1, tools/tiff2ps.c, tools/tiffcp.c,
 	tools/tiffdither.c: Sync tool usage printouts and man pages with
 	reality (quite a few options had escaped being documented in one
 	or both places).  Per an old report from Miroslav Vadkerti.

2013-01-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tools/tiff2ps.c:Fix bug in auto rotate option code. Once a
	rotation angle was set by the auto rotate check, it was retained
	for all pages that followed instead ofa being retested for each
	page.  Patch by Richard Nolde.

2013-01-18  Frank Warmerdam  <warmerdam@google.com>

	* libtiff/tif_write.c: tmsize_t related casting warning fixed for
	64bit linux.

	* libtiff/tif_read.c: uint64/tmsize_t change for MSVC warnings.
	http://bugzilla.maptools.org/show_bug.cgi?id=2427

2012-12-20  Tom Lane  <tgl@sss.pgh.pa.us>

	* test/raw_decode.c: Relax raw_decode's pixel-value checks so that
	it will pass with more versions of libjpeg.  (There are at least
	three in active use now, and JPEG_LIB_VERSION doesn't tell us
	enough to uniquely identify expected results.)

2012-12-12  Tom Lane  <tgl@sss.pgh.pa.us>

	* libtiff/tif_print.c: Fix TIFFPrintDirectory's handling of
	field_passcount fields: it had the TIFF_VARIABLE and
	TIFF_VARIABLE2 cases backwards.

2012-12-10  Tom Lane  <tgl@sss.pgh.pa.us>

	* tools/ppm2tiff.c: Improve previous patch for CVE-2012-4564:
 	check the linebytes calculation too, get the max() calculation
 	straight, avoid redundant error messages, check for malloc
 	failure.

2012-12-10  Tom Lane  <tgl@sss.pgh.pa.us>

	* libtiff/tif_pixarlog.c: Improve previous patch for CVE-2012-4447
 	(to enlarge tbuf for possible partial stride at end) so that
 	overflow in the integer addition is detected.  Per gripe from
 	Huzaifa Sidhpurwala.

2012-12-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tools/tiffset.c: tiffset now supports a -u option to unset a
	tag.  Patch by Zach Baker. See
	http://bugzilla.maptools.org/show_bug.cgi?id=2419

2012-11-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* automake: Update Automake to 1.12.5 release.

	* libtiff/tif_{unix,vms,win32}.c (_TIFFmalloc): ANSI C does not
	require malloc() to return NULL pointer if requested allocation
	size is zero.  Assure that _TIFFmalloc does.

2012-11-01  Frank Warmerdam  <warmerdam@pobox.com>

	* tools/ppm2tiff.c: avoid zero size buffer vulnerability.
	CVE-2012-4564 - Thanks to Huzaifa Sidhpurwala of the
	Red Hat Security Response team for the fix.

2012-10-18  Frank Warmerdam  <warmerdam@google.com>

	* tif_zip.c: Avoid crash on NULL error messages.

2012-09-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff 4.0.3 released.

2012-09-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am: Update to Automake 1.12.4

2012-08-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.in: Update to Automake 1.12.3

	* libtiff{tiff.h, tif_print.c, tif_dirinfo.c, tif_dirread.c}: Add
	some TIFF/FX support in libtiff.  Add the tag definitions to
	tiff.h.  Add the related TIFF field definitions to tif_dirinfo.c,
	and also fixes an error in a comment.  Adds the photometric values
	to tif_print.c, and fixes a bug.  These changes are by Steve
	Underwood.

2012-08-13  Frank Warmerdam  <warmerdam@google.com>

	* libtiff/tif_write.c: Fix bug rewriting image tiles in a
	compressed file: http://trac.osgeo.org/gdal/ticket/4771

2012-08-02  Frank Warmerdam  <warmerdam@google.com>

	* libtiff/tif_dirread.c: report error in case of mismatch value
	counts for tags (ie. DotRange).

2012-07-26  Tom Lane  <tgl@sss.pgh.pa.us>

	* libtiff/{tiffio.h, tif_dirinfo.c, libtiff.def}: Add six new
 	functions TIFFFieldTag(), TIFFFieldName(), TIFFFieldDataType(),
	TIFFFieldPassCount(), TIFFFieldReadCount(), TIFFFieldWriteCount()
	as external accessors for the opaque type TIFFField.

	* tools/tiffset.c: Make tiffset use the above functions instead of
	relying on library private headers.

2012-07-19  Tom Lane  <tgl@sss.pgh.pa.us>

	* tools/tiff2pdf.c: Fix two places where t2p_error didn't get set
	after a malloc failure.  No crash risk AFAICS, but the program
	might not report exit code 1 as desired.  h/t mancha@mac.hush.com

2012-07-18  Tom Lane  <tgl@sss.pgh.pa.us>

	* tools/tiff2pdf.c: Fail when TIFFSetDirectory() fails.  This
	prevents core dumps or perhaps even arbitrary code execution when
	processing a corrupt input file (CVE-2012-3401).

2012-07-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* test/raw_decode.c (main): Test fixes to work with IJG JPEG 7+.
	IJG JPEG 7+ uses a different upsampling algorithm which produces
	different numeric results.

	* libtiff/tif_jpeg.c (JPEGPreDecode): Patch from Even Rouault to
	work with IJG JPEG 7+.

2012-07-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* test/raw_decode.c: Add changes so that test can run with build
	directory outside of source directory.

2012-07-02  Frank Warmerdam  <warmerdam@google.com>

	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.

	* libtiff/tif_pixarlog.c: Make sure tbuf is large enough for one
	full "stride" past the end.

2012-06-19  Frank Warmerdam  <warmerdam@google.com>

	* libtiff/tif_packbits.c: fix read past end of data buffer.

2012-06-15  Frank Warmerdam  <warmerdam@google.com>

	*  libtiff 4.0.2 released.

	* tools/tif2pdf.c, tools/tifdump.c: avoid uninitialized variable
	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 retrieve the value of unsupported tags.

2012-03-30  Frank Warmerdam  <warmerdam@google.com>

	* tif_getimage.c: Fix size overflow (zdi-can-1221,CVE-2012-1173)
	care of Tom Lane @ Red Hat.

2012-02-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff 4.0.1 released.

	* Update automake used to 1.11.3.

	* libtiff/tiffio.h: Use double-underbar syntax in GCC printf
	attribute specification to lessen the risk of accidental macro
	substitution.  Patch from Vincent Torri.

2012-01-31  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_dir.c, libtiff/tif_dirread.c: Extra caution around
	assumption tag fetching is always successful.

	* libtiff/tif_jpeg.c: Extra caution for case where sp is NULL.

2012-01-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Add support for using library symbol versioning on
	ELF systems with the GNU linker.  Support is enabled via
	--enable-ld-version-script.  Disabled by default for now until
	there is a decision for how to deploy a libtiff with versioned
	symbols after libtiff 4.0.0 was already released.

2011-12-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/tif_win32.c: Eliminate some minor 64-bit warnings in

	tif_win32.c.  Patch by Edward Lam.

	* configure.ac: Add libtiff private dependency on -llzma for
	pkg-config.  Patch by Mark Brand.
	Updated Automake to 1.11.2.

2011-12-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff 4.0.0 released.

2011-12-08  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_dirread.c, libtiff/tif_read.c: more cautious checking
	of _TIFFFillStriles() results (#gdal 4372)

2011-12-07  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_dirread.c: fixes to deal with invalid files where
	_TIFFFillStriles() fails, and we try to chop up strips (gdal #4372)

	* libtiff/tif_dirread.c: fix error reporting when there is no
	tag information struct and name (gdal #4373)

2011-10-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Update GNU libtool to 2.4.2.

	* tools/tiffsplit.c (tiffcp): TIFFGetField count field should be
	uint32 type for TIFFTAG_JPEGTABLES.  Patch by Christophe
	Deroulers.

2011-06-21  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/libtiff.def: Restore TIFFMergeFieldInfo.

2011-05-31  Jim Meyering  <meyering@redhat.com>

	* libtiff/tif_dirread.c (TIFFFetchStripThing): Free "data" also
	upon failure to allocate "resizeddata".
	* tools/tiff2ps.c (PSDataBW): Zero buffer *after* checking for
	allocation failure, not before.
	* libtiff/tif_ojpeg.c: plug leaks on OJPEG read failure path
	* tools/rgb2ycbcr.c (cvtRaster): unchecked malloc
	* libtiff/tif_jpeg.c, tools/tiff2pdf.c, tools/tiff2ps.c: mark
	NULL-deref and possible overflow
	* tools/tiff2pdf.c: remove decl+set of set-but-not-used local, "written"
	* libtiff/tif_jpeg.c (JPEGInitializeLibJPEG): Remove declaration
	and set of otherwise unused local, data_is_empty.
	* libtiff/tif_jpeg.c (JPEGDecodeRaw) [JPEG_LIB_MK1_OR_12BIT]:
	Diagnose out-of-memory failure and return 0 rather than
	dereferencing NULL.

2011-05-24  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_dirread.c: produce special error message for zero tag
	directories instead of error out on the malloc(0) failure.

2011-05-16  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_dirinfo.c: Restore TIFFMergeFieldInfo() and
	related declarations as they are in active use by libraries
	such as libgeotiff, and work just fine.  (#2315)

2011-04-20  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_dirinfo.c,tiffio.h: Remove the obsolete
	TIFFMergeFieldInfo/TIFFFindFieldInfo/TIFFFindFieldInfoByName API.
	http://bugzilla.maptools.org/show_bug.cgi?id=2315

	* libtiff/libtiff.def: add some missing (64bit) APIs.
	http://bugzilla.maptools.org/show_bug.cgi?id=2316

2011-04-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff 4.0.0beta7 released.

2011-04-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Should use AC_CANONICAL_HOST since host specifies
	the run-time target whereas target is used to specify the final
	output target if the package is a build tool (like a compiler),
	which libtiff is not.  Resolves libtiff bug 2307 "Use
	AC_CANONICAL_HOST macro".

2011-04-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Support configuring TIFF_INT64_FORMAT and
	TIFF_UINT64_FORMAT appropriately for MinGW32.

	* tools/tiffdump.c (ReadDirectory): MinGW32 needs to use WIN32
	printf conventions for 64-bit types because it uses the WIN32 CRT.

	* libtiff/{tif_dumpmode.c,tif_luv.c,tif_lzw.c,tif_print.c,
	tif_read.c,tif_strip.c,tif_thunder.c}: MinGW32 needs to use WIN32
	printf conventions for 64-bit types because it uses the WIN32 CRT.

	* tools/tiff2pdf.c (t2p_write_pdf_string): Fix printf syntax not
	understood by WIN32 CRT.

	* libtiff/tif_ojpeg.c: Fixes to compile with MinGW32 GCC.

	* tools/fax2ps.c (main): Use tmpfile() rather than mkstemp() since
	it is much more portable.  Tmpfile is included in ISO/IEC
	9899:1990 and the WIN32 CRT.

2011-03-26  Frank Warmerdam  <warmerdam@pobox.com>

	* tools/tiffset.c: add -d and -sd switches to allow operation on
	a particular directory, not just the first (jef).

2011-03-21  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_thunder.c: Correct potential buffer overflow with
	thunder encoded files with wrong bitspersample set.  The libtiff
	development team would like to thank Marin Barbella and TippingPoint's
	Zero Day Initiative for reporting this vulnerability (ZDI-CAN-1004,
	CVE-2011-1167).
	http://bugzilla.maptools.org/show_bug.cgi?id=2300

2011-03-10  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_fax3.h: Fix to last change allowing zero length
	runs at the start of a scanline - needed for legal cases.

2011-03-02  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_fax3.h: Protect against a fax VL(n) codeword commanding
	a move left.  Without this, a malicious input file can generate an
	indefinitely large series of runs without a0 ever reaching the right
	margin, thus overrunning our buffer of run lengths.  Per CVE-2011-0192.
	This is a modified version of a patch proposed by Drew Yao of Apple
	Product Security.  It adds an unexpected() report, and disallows the
	equality case, since emitting a run without increasing a0 still allows
	buffer overrun.

2011-02-23  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_jpeg.c: avoid divide by zero in degenerate case (#2296)

	* tools/tiff2rgba.c: close source file on error to make leak
	detection easier.

	* libtiff/tif_getimage.c: avoid leaks if TIFFRGBAImageBegin() fails.

	_SUPPORT)

2011-02-18  Frank Warmerdam  <warmerdam@pobox.com>

	* configure.ac, configure: Added support for --enable-chunky-strip-read
	configure option to enable the experimental feature from a couple
	months ago for reading big strips in chunks.

	* configure.ac, tif_read.c, tif_readdir.c, tif_dir.h, tiffiop.h,
	tif_write.c, tif_print.c, tif_jpeg.c, tif_dirwrite.c, tif_write.c:
	Implement optional support for deferring the load of strip/tile
	offset and size tags for optimized scanning of directories.  Enabled
	with the --enable-defer-strile-load configure option (DEFER_STRILE_LOAD
	#define in tif_config.h).

2011-02-11  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_print.c: remove unused variable.

2011-02-09  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_win32.c: avoid error/warning buffer overrun problem
	with non-console (popup message) builds on win32.

	http://bugzilla.maptools.org/show_bug.cgi?id=2293

2011-01-24  Olivier Paquet  <olivier.paquet@gmail.com>

	* libtiff/{tif_dir.{h,c}, tif_dirinfo.c, tif_dirread.c, tif_dirwrite.c,
	tif_print.c, tiff.h, tiffiop.h} : Added support for
	TIFFTAG_SMINSAMPLEVALUE and TIFFTAG_SMAXSAMPLEVALUE to have different
	values for each sample. Presents the min/max of all samples by default for
	compatibility. TIFFSetField/TIFFGetField can be made to handle those tags
	as arrays by changing the new TIFFTAG_PERSAMPLE pseudo tag.
	http://www.asmail.be/msg0055458208.html

2011-01-06  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_pixarlog.c: Note that tif_rawcc/tif_rawcp are not
	maintained.

	* libtiff/tif_zip.c: Maintain tif_rawcc/tif_rawcp when decoding
	for CHUNKY_STRIP_READ_SUPPORT.

	* libtiff/tif_jpeg.c: ensure that rawcc and rawcp are maintained
	during JPEGPreDecode and JPEGDecode calls.
	* libtiff/tif_read.c: larger read ahead for CHUNKY_STRIP_READ_SUPPORT,
	as compression formats like JPEG keep 16 lines interleaved in a sense
	and might need to touch	quite a bit of data.

	http://trac.osgeo.org/gdal/ticket/3894

2011-01-03  Lee Howard <faxguy@howardsilvan.com>

	* libtiff/tif_jpeg.c: Fix regressions with 2 and 3 band images

	* tools/tiffcp.c, man/tiffcp.1: Added support for specifying the
	compression level parameter (preset) for Deflate and LZMA encoders,
	e.g "-c lzma:p1" or "-c zip:p9".

	* libtiff/tif_lzma.c: Properly set the LZMA2 compression level
	(preset) in LZMAVSetField().

2010-12-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/Makefile.am (libtiff_la_SOURCES): Added tif_lzma.c to
	Makefile.

2010-12-14  Andrey Kiselev  <dron@ak4719.spb.edu>

	* configure.ac, libtiff/{tif_codec.c, tif_config.h.in, tiff.h,
	tiffiop.h, tif_lzma.c}, tools/tiffcp.c, man/tiffcp.1: Implement a new

	* tools/tiff2pdf.c: Fixed ID buffer filling in
	t2p_write_pdf_trailer(), thanks to Dmitry V. Levin.

2010-07-07  Andrey Kiselev  <dron@ak4719.spb.edu>

	* libtiff/tif_dirread.c: Really reset the tag count in CheckDirCount()
	to expected value as the warning message suggests. As per bug
	http://bugzilla.maptools.org/show_bug.cgi?id=1963

2010-07-06  Andrey Kiselev  <dron@ak4719.spb.edu>

	* tools/tiffset.c: Properly handle TIFFTAG_PAGENUMBER,
	TIFFTAG_HALFTONEHINTS, TIFFTAG_YCBCRSUBSAMPLING, TIFFTAG_DOTRANGE
	which should be set by value.

	* libtiff/tif_dirinfo.c: Don't use assertions in _TIFFFieldWithTag()
	and _TIFFFieldWithName() if the tag is not found in the tag table.
	This should be normal situation and returned NULL value should be
	properly handled by the caller.

2010-07-02  Andrey Kiselev  <dron@ak4719.spb.edu>

	* libtiff/tif_getimage.c: Avoid wrong math du to the signed/unsigned
	integer type conversions. As per bug
	http://bugzilla.maptools.org/show_bug.cgi?id=2207

	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>

	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 every time
	JPEGSetupEncode() is called if the tables already seem to be
	established.  This prevents spurious updates and rewriting of
	directories with jpegtables when doing updates to existing images.
	http://trac.osgeo.org/gdal/ticket/3539

2010-04-20  Olivier Paquet  <olivier.paquet@gmail.com>

	* libtiff/tif_dirinfo.c: Use correct set_field_type for
	TIFFTAG_PIXAR_IMAGEFULLWIDTH, TIFFTAG_PIXAR_IMAGEFULLLENGTH,
	TIFFTAG_PIXAR_MATRIX_WORLDTOSCREEN and TIFFTAG_PIXAR_MATRIX_WORLDTOCAMERA.
	They were unreadable with TIFF_SETGET_UNDEFINED, a regression from 3.9.2.
	http://bugzilla.maptools.org/show_bug.cgi?id=2139

2010-04-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/tif_dir.c (_TIFFVSetField): Add a special error case for
	when the tag count value is zero.  Error handling is still a
	regression since in 3.9.2, empty tags are skipped (with a warning)
	rather than returning a hard error and refusing to read the file.

	* tools/ppm2tiff.c (main): While case for parsing comment line
	requires extra parenthesis to work as expected.  Reported by
	Thomas Sinclair.

2010-04-02  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_read.c (primarily): Add support for
	CHUNKY_STRIP_READ_SUPPORT where large strips are
	read in chunks for applications using TIFFReadScanline().
	This is intended to make it more practical work with very
	large compressed one-strip files.   Feature is off by default.
	Enable by defining CHUNK_STRIP_READ_SUPPORT as a macro.
	http://trac.osgeo.org/gdal/ticket/3514

2010-03-31  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_flush.c: Use TIFFRewriteDirectory() when flushing
	directories so previously placed directories will be migrated to
	the end of file if needed.

2010-03-30  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_lzw.c: change type of dec_bitsleft field to uint64
	to support operating on strips/tiles of more than 256MB.
	http://trac.osgeo.org/gdal/ticket/3512

2010-03-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/tif_aux.c (_TIFFCheckRealloc): Improve error message so
	that it is clearly a memory allocation error message, and also
	includes the size of the allocation request.

2010-02-22  Lee Howard  <faxguy@howardsilvan.com>

	* libtiff/tif_jpeg.c: Do not generate a JPEGTables tag when creating
	the JPEG TIFF as is is not required in order to prevent it from
	being unused and filled with invalid data.  (Leave it to be
	generated by later activity.)
	http://bugzilla.maptools.org/show_bug.cgi?id=2135
	* tools/tiff2pdf.c: Write the JPEG SOI headers into the TIFF strip
	data rather than skipping them.  This fixes the ability to view in
	Acrobat Reader, Evince, and Ghostscript.
	http://bugzilla.maptools.org/show_bug.cgi?id=2135
	* libtiff/tif_fax3.c: Don't return error on badly-terminated MMR
	strips.
	http://bugzilla.maptools.org/show_bug.cgi?id=2029

2009-12-03  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_jpeg.c: Made JPEGDecodeRaw() check for buffer overruns.
	Made so that when working with downsampled images a stub function
	reporting an error is used for tif_decoderow.  We cannot meaningfully
	support reading scanlines in this situation.  (#1936)

	* libtiff/tif_jpeg.c: Ensure that tif_scanlinesize is computed after
	resetting of the upsampling values (gdal:#3259).
	http://bugzilla.maptools.org/show_bug.cgi?id=1936

2009-11-30  Frank Warmerdam  <warmerdam@pobox.com>

	* contrib/dbs/tiff-grayscale.c, contrib/tif-palette.c,
	tools/ras2tiff.c: Fix resource leaks on error.
	http://bugzilla.maptools.org/show_bug.cgi?id=2121

	* libtiff/tif_{aux.c,dir.c,dir.h,dirinfo.c}: Return to handling
	TIFFTAG_REFERENCEBLACKWHITE as a field in the TIFF directory instead
	of as a custom(generic) field to avoid a potential reentrancy problem.
	http://bugzilla.maptools.org/show_bug.cgi?id=2125

	* libtiff/tif_color.c, libtiff/tif_getimage.c, libtiff/tiffio.h,
	man/TIFFcolor.3tiff: Make TIFFDisplay argument in TIFFCIELabToRGBInit
	const, and display_sRGB static and const.
	http://bugzilla.maptools.org/show_bug.cgi?id=2124

2009-11-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	Resolves "Bug 2067 - Visual Studio 2005 64-bit warnings in
	tif_lzw.c", http://bugzilla.maptools.org/show_bug.cgi?id=2067

	* libtiff/tif_pixarlog.c (PixarLogEncode): Fix non-important
	warning noticed in Visual Studio 2005 build. Resolves "Bug 2068 -
	Visual Studio 2005 64-bit warning in tif_pixarlog.c",
	http://bugzilla.maptools.org/show_bug.cgi?id=2068

2009-10-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/tif_dirread.c: Eliminate GCC "dereferencing type-punned
	pointer" warnings.

2009-10-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* html/tools.html: Add manual page links, and a summary
	description of tiffcrop.

2009-10-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

2009-09-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tools/tiffcrop.c, man/tiffcrop.1: New tiffcrop from Richard
	Nolde.  Major updates to add significant functionality for reading
	and writing tile based images with bit depths not a multiple of 8
	which cannot be handled by tiffcp.

2009-09-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/tif_ojpeg.c (OJPEGWriteHeaderInfo): IJG JPEG 7 needs
	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

2009-09-03  Frank Warmerdam  <warmerdam@pobox.com>

	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
	PNM formats so that we will be able to test more of the tools.
	While adding these test images I notice that bmp2tiff and gif2tiff
	only support ancient versions of their respective formats.

2009-08-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff 4.0.0alpha4 released.

	* HOWTO-RELEASE: Improved release instructions.

	* test/Makefile.am, test/tiffcrop*.sh: Split previously existing
	tiffcrop.sh into a collection of many specific tests.  Re-wrote
	all of the existing tests to be based on some simple shell
	functions.  Make distcheck works again.

	Export certain variables (MAKE, MAKEFLAGS, MEMCHECK) to tests and
	added 'memcheck' and 'ptrcheck' targets to make it easy to run the
	tests under valgrind.

2009-08-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* test/tiffcp-logluv.sh: Fix test so that it works with a VPATH
	build.

	* test/Makefile.am (AUTOMAKE_OPTIONS): Colorized tests was not
	actually activated since it needed to be enabled in this
	Makefile.am.  Also activated parallel-tests mode since it offers
	useful features such as per-test .log files and a summary test
	report .log file.

2009-08-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Updated autotools.  Autoconf 2.64, Automake 1.11,

	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 sought 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)
	with control logic to return runtime errors (c/o Even Rouault) (#1927).

2008-06-17  Frank Warmerdam  <warmerdam@pobox.com>

	* li2008-04-15  Andrey Kiselev  <dron@ak4719.spb.edu>

btiff/tif_win32.c: Replace custom Win32 memory api with generic
	POSIX one.  No apparent value to use of GlobalAlloc() in the modern
	age.  http://bugzilla.maptools.org/show_bug.cgi?id=1885

	* libtiff/tiffconf.vc.h: Added JBIG_SUPPORT and MDI_SUPPORT items
	in windows version (care of Edward Lam).

2008-05-24  Frank Warmerdam  <warmerdam@pobox.com>

	* tif_codec.c: Avoid NULL pointer dereferencing for exotic

2008-05-18  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_dirinfo.c: Use TIFF_SETGET_ASCII for PIXAR_TEXTUREFORMAT
	and PIXAR_WRAPMODES instead of TIFF_SETGET_UNDEFINED.  Not exactly clear
	why this is needed.

2008-05-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am (ACLOCAL_AMFLAGS): Libtool 2.2.4 does not like
	"ACLOCAL_AMFLAGS=-I ./m4".  It wants "ACLOCAL_AMFLAGS=-I m4".

2008-04-15  Andrey Kiselev  <dron@ak4719.spb.edu>

	* test/: Test suite updated. Everything is passed now.

	* libtiff/tif_dirinfo.c: Fixed description of the
	TIFFTAG_NUMBEROFINKS tag.

2008-04-14  Andrey Kiselev  <dron@ak4719.spb.edu>

	* libtiff/{tif_dirread.c, tif_dirwrite.c, tiffiop.h}:
	Get rid of some of "dereferencing type-punned" warnings by converting
	tdir_offset field of TIFFDirEntry structure into union.

2008-04-10  Andrey Kiselev  <dron@ak4719.spb.edu>

	* libtiff/{tif_flush.c, tif_dirwrite.c, tiffio.h, tiffiop.h}:
	TIFFRewriteField() renamed into _TIFFRewriteField() and moved out
	from the public interface. Type of its 'count' parameter changed
	from uint32 to tmsize_t.

	* /libtiff/tiffiop.h: Make tif_nfields and tif_nfieldscompat fields
	of the tiff structure have the size_t type instead of uint32.

2008-04-09  Andrey Kiselev  <dron@ak4719.spb.edu>

	* tools/tiffdump.c: Added support for MSVS 6.0.

	* libtiff/tif_dirread.c: Use custom functions _TIFFUInt64ToFloat()
	and _TIFFUInt64ToDouble() to convert 64-bit integers into floating
	point values on MSVS 6.0 platform.

2008-03-14  Frank Warmerdam  <warmerdam@pobox.com>

	* tif_dirread.c: Removed sanity checks on tags larger than 4MB in
	TIFFReadDirEntryArray() since they are interfering with seemingly
	legitimate files.  http://trac.osgeo.org/gdal/ticket/2005

2008-02-09  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* tif_dirread.c: Added handling for the case of number of values for
	PageNumber tag different from 2 (previously resulted in an assert
	indicating lack of handling and was forgotten about)

2008-02-01  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_jpeg.c: Do not try to fixup subsampling tags based on
	the actual jpeg data stream if the first strip/tile has zero size.
	This is the case when GDAL creates a new file with zero sizes, closes
	and reopens it.

2008-01-07  Frank Warmerdam  <warmerdam@pobox.com>

	* tools/tiff2ps.c: fix up 64bit issues (from Edward Lam).

2008-01-01  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_dirwrite.c: #ifdef out lots of unused functions.

	* Makefile.vc, libtiff/Makefile.vc, tools/Makefile.vc: Improve clean
	targets.

	* tools/tiffinfo.c, tools/tiffcmp.c, tools/gif2tiff.c, tools/bmp2tiff.c
	tools/tiff2pdf.c: Fix 64-bit warnings when compiling under MSVC 2005
	(x64).

	* tools/tiffset.c: Changes to reflect the fact that TIFFFieldWithTag()
	and TIFFFieldWithName() now return TIFFField pointers instead of
	TIFFFieldInfo pointers.

	* tools/tiffdump.c: Added ssize_t typedef on Windows since it doesn't
	exist. This makes it compile again on Windows

	* tif_aux.c, tif_getimage.c, tif_next.c, tif_predict.c, tif_win32.c,
	tiffconf.vc.h: Various 64bit fixes from Edward Lam identified on win64.

	* test/rewrite_tag.c: New test for TIFFRewriteField().

2007-12-31  Frank Warmerdam  <warmerdam@pobox.com>

	* tif_dirwrite.c: Added TIFFRewriteField().  This new function
	rewrites one field "on disk" updating an existing directory
	entry.  Lots of limitations still...

	* tiffiop.h, tif_write.c, tif_dirread.c, tif_flush.c: Keep track of
	TIFF_DIRTYSTRIP separately from TIFF_DIRTYDIRECT to indicate that
	the strip offset/size values are dirty but nothing else about the
	directory is dirty.  In flush handle "just stripmaps dirty" as a
	special case that just rewrites these values without otherwise
	modifying the directory on disk using TIFFRewriteField().

	We also modify logic so that in update mode the directory is not
	marked dirty on read, but only when something is changed.  This
	means we need to keep track of updates to the stripmap stuff in
	TIFFAppendToStrip().

2007-12-10  Frank Warmerdam  <warmerdam@pobox.com>

	* tif_jpeg.c: Improve ability to switch between encoding and decoding
	in the jpeg code (gdal bug #2033).

2007-11-23  Frank Warmerdam  <warmerdam@pobox.com>

	* tif_dir.c, tif_dirread.c, tif_dirwrite.c, tif_read.c, tif_write.c,
	tiffiop.h: Added TIFF_BUF4WRITE flag to indicate if contents of the
	rawcp/rawcc buffer are for writing and thus may require flushing.
	Necessary to distinguish whether they need to be written to disk when
	in mixed read/write mode and doing a mixture of writing followed by
	reading.  http://trac.osgeo.org/gdal/ticket/1758

2007-11-23  Andrey Kiselev  <dron@ak4719.spb.edu>

	* configure.com, libtiff/tif_vms.c: Better OpenVMS support. Patches
	from Alexey Chupahin.

2007-11-02  Frank Warmerdam  <warmerdam@pobox.com>

	* tif_write.c: Rip out the fancy logic in TIFFAppendToStrip() for
	establishing if an existing tile can be rewritten to the same location
	by comparing the current size to all the other blocks in the same
	directory.  This is dangerous in many situations and can easily
	corrupt a file.  (observed in esoteric GDAL situation that's hard to
	document).  This change involves leaving the stripbytecount[] values
	unaltered till TIFFAppendToStrip().  Now we only write a block back
	to the same location it used to be at if the new data is the same
	size or smaller - otherwise we move it to the end of file.

	* tif_dirwrite.c: Try to avoid writing out a full readbuffer of tile
	data when writing the directory just because we have BEENWRITING at
	some point in the past.  This was causing odd junk to be written out
	in a tile of data when a single tile had an interleaving of reading
	and writing with reading last.  (highlighted by gdal
	autotest/gcore/tif_write.py test 7.

	* tif_predict.c: use working buffer in PredictorEncodeTile to avoid
	modifying callers buffer.
	http://trac.osgeo.org/gdal/ticket/1965

	* tif_predict.c/h: more fixes related to last item, keeping a
	distinct pfunc for encode and decode cases as these were getting
	mixed up sometimes.
	http://trac.osgeo.org/gdal/ticket/1948

2007-11-01  Frank Warmerdam  <warmerdam@pobox.com>

	* tif_predict.c/h, tif_lzw.c, tif_zip.c: Improvements so that
	predictor based encoding and decoding works in read-write update
	mode properly.
	http://trac.osgeo.org/gdal/ticket/1948

2007-10-24  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* tif_dirread.c: Fixed problem with bogus file triggering
	assert(td->td_planarconfig == PLANARCONFIG_CONTIG) in
	ChopUpSingleUncompressedStrip

2007-10-22  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* tif_jpeg.c: Resolved buffer incrementation bug that lead to faulty images
	at best, access violation at worst, when subsampled JPEG compressed imagery
	is decoded without the JPEG_COLORMODE feature

2007-10-11  Frank Warmerdam  <warmerdam@pobox.com>

	* html/index.html: Update "people responsible" section.

2007-10-05  Frank Warmerdam  <warmerdam@pobox.com>

	* 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.

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

	* libtiff/{tiffiop.h, tif_aux.c}:  Added _TIFFUInt64ToFloat() and
	_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
	integer constants.

	* libtiff/{Makefile.am, Makefile.v}: Do not distribute tiffconf.h,
	remove tif_config.h/tiffconf.h during cleaning. As per bug

	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,
	tif_fax3.c, tif_dirread.c, tif_dirwrite.c, tif_close.c, tif_ojpeg.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.

	http://bugzilla.remotesensing.org/show_bug.cgi?id=1566

	Patch from William Bader.

	* tools/tiff2pdf.c: Fix for TIFFTAG_JPEGTABLES tag fetching and
	significant upgrade of the whole utility as per bug

	http://bugzilla.remotesensing.org/show_bug.cgi?id=1560

	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.

	allow returning -1 for errors.
	* libtiff/tiffconf.vc.h: Add porting type definitions 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
	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.

2007-04-06  Andrey Kiselev  <dron@ak4719.spb.edu>

	* tools/tiffcrop.c, man/tiffcrop.1: Significant update in

	factor. This bug is mentioned in:
	http://bugzilla.remotesensing.org/show_bug.cgi?id=1390
	http://www.asmail.be/msg0054766825.html

2007-03-07  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* libtiff/tif_win32.c: made inclusion of windows.h unconditional

	* libtiff/tif_win32.c: replaced preprocessor indication for consiously
	unused arguments by standard C indication for the same

2007-02-27  Andrey Kiselev  <dron@ak4719.spb.edu>

2006-09-27  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_lzw.c, libtiff/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.
	http://bugzilla.remotesensing.org/show_bug.cgi?id=757

2006-09-20  Frank Warmerdam  <warmerdam@pobox.com>

	to bug report by Peng Gao with black strip at bottom of images.

2006-07-12  Frank Warmerdam  <warmerdam@pobox.com>

	* 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.

2006-07-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* {configure.ac, libtiff/tif_config.h.vc, libtiff/tif_jbig.c}
	(JBIGDecode): jbg_newlen is not available in older JBIG-KIT and
	its use does not appear to be required, so use it only when it is
	available.

	EstimateStripByteCounts() for case where entry 0 and 1 are unequal
	but one of them is zero.
	  http://bugzilla.remotesensing.org/show_bug.cgi?id=1204

2006-06-08  Andrey Kiselev  <dron@ak4719.spb.edu>

	_CRT_SECURE_NO_DEPRECATE to avoid noise on VS2005.

2006-04-12  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* libtiff/tif_getimage.c: Added support for planarconfig separate
	non-subsampled YCbCr (i.e. separate YCbCr with subsampling [1,1])

2006-04-11  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* libtiff/tif_getimage.c: Revision of all RGB(A) put routines
	- Conversion of unassociated alpha to associated alpha now done with
	  more performant LUT, and calculation more correct
	- Conversion of 16bit data to 8bit data now done with
	  more performant LUT, and calculation more correct
	- Bugfix of handling of 16bit RGB with unassociated alpha

2006-04-11  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* libtiff/tif_getimage.c:
	- When there is no alpha, gtTileSeparate and gtStripSeparate allocated
	  buffer for alpha strile and filled it, only to never read it back.
	  Removed allocation and fill.
	- Minor rename of vars in gtTileSeparate and gtStripSeparate
	  anticipating planned functionality extension

2006-04-08  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* libtiff/tif_getimage.c: renamed pickTileContigCase to PickContigCase
	and pickTileSeparateCase to PickSeparateCase as both work on strips as
	well

	* libtiff/tif_getimage.c: moved img->get selection from
	TIFFRGBAImageBegin into PickContigCase and PickSeparateCase to create
	logical hook for planned functionality extension

2006-04-08  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* libtiff/tif_ojpeg.c: resolved memory leak that was a consequence
	of inappropriate use of jpeg_abort instead of jpeg_destroy

2006-04-07  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* libtiff/tif_getimage.c: replaced usage of TIFFScanlineSize in
	gtStripContig with TIFFNewScanlineSize so as to fix buggy behaviour
	on subsampled images - this ought to get sorted when we feel brave
	enough to replace TIFFScanlineSize altogether

	* libtiff/tif_ojpeg.c: fixed bug in OJPEGReadSkip

2006-04-04  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	YCbCr and desubsampling

2006-03-29  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/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.

2006-03-25  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* libtiff/tif_jpeg.c: strip size related bugfix in encode raw

	* libtiff/tif_strip.c: temporarily added two new versions of
	TIFFScanlineSize
	  - TIFFNewScanlineSize: proposed new version, after all related
	    issues and side-effects are sorted out
	  - TIFFOldScanlineSize: old version, from prior to 2006-03-21 change
	This needs further sorting out.

2006-03-25  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* contrib/addtiffo/tif_ovrcache.c: bugfix to correctly pass size
	of last truncated strip data to TIFFWriteEncodedStrip

	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.

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

	the library, but makes it work better with RGBA files produced by
	lots of applications that don't mark the alpha values properly.

	detect failure.

	* libtiff/tif_dir.c: removed the auto replacement of

	* 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 practically
	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

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

2001-03-16  Frank Warmerdam  <warmerdam@pobox.com>

	* tif_dirinfo.c: moved definition of copyright tag in field list.

	* libtiff/libtiff.def: Brent Roman submitted new version adding
	several 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>

	* html/libtiff.html: Fixed arguments in example for TIFFRGBAImageGet()

2000-12-28  Frank Warmerdam  <warmerdam@pobox.com>

	* Added RELEASE-DATE file to release file list.

	  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
	with correct building on older systems.  If so, please let me know.

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.

2000-10-20  Frank Warmerdam  <warmerda@cs46980-c>

	* tif_getimage.c: Fixed RGBA translation for YCbCr images for which
	the strip/tile width and height aren't multiples of the sampling size.
	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>

	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
	white is properly recovered.

	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>

	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

	* Reverted tif_flush change.

2000-09-14  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.

	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>

	* Modified tiffio.h logic with regard to including windows.h.  It
	won't include it when building with __CYGWIN__.

	* Modified tif_unix.c to support 2-4GB seeks if USE_64BIT_API is
	  set to 1, and added default (off) setting in tiffconf.h.  This
	  should eventually be set by the configure script somehow.

	  The original work on all these 2-4GB changes was done by
	  Peter Smith (psmith@creo.com).

	* Modified tif_win32.c to support 2-4GB seeks.

	* tentatively changed toff_t to be unsigned instead of signed to
	  facilitate support for 2-4GB files.

	* Updated a variety of files to use toff_t.  Fixed some mixups
