	* libtiff/: tif_codec.c, tif_compress.c, tiffiop.h: 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).

	changed. Now it has used tif->tif_decodestatus and
	tif->tif_encodestatus.
	Should fix http://bugzilla.remotesensing.org/show_bug.cgi?id=119 (in
	case of __cvs_8.tif test image).

	files by skipping bad strips.
	Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=100

2002-04-03  Frank Warmerdam  <[email protected]>

	http://bugzilla.remotesensing.org/show_bug.cgi?id=111

	* tif_print.c: Fixed so that ASCII FIELD_CUSTOM values with
	passcount set FALSE can be printed (such as TIFFTAG_SOFTWARE).

	* libtiff/tif_dir.c,tif_dirinfo.c,tif_dir.h,tif_ojpeg.c: modified so
	that TIFFTAG_SOFTWARE uses FIELD_CUSTOM as an example.

2002-03-26  Dwight Kelly  <[email protected]>

	* libtiff/: tiff.h, tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c,
	tif_dirwrite.c: Added get/put code for new tag XMLPACKET as defined

	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).

2002-03-26  Andrey Kiselev  <[email protected]>

	* libtiff/: tif_getimage.c: TIFFReadRGBAStrip and TIFFReadRGBATile
	now also uses TIFFRGBAImageOK before reading. This is additional fix
	for http://bugzilla.remotesensing.org/show_bug.cgi?id=110

2002-03-25  Andrey Kiselev  <[email protected]>

	* libtiff/: tif_getimage.c: Additional check for supported

	* libtiff/: tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c,
	tif_dirwrite.c: Added routine TIFFDataWidth for detrmining
	TIFFDataType sizes instead of working with tiffDataWidth array
	directly. Should prevent out-of-borders bugs in case of unknown or
	broken data types.  EstimateStripByteCounts routine modified, so it
	won't work when tags with uknown sizes founded.
	Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=109

2002-03-13  Andrey Kiselev  <[email protected]>

	* libtiff/tif_getimage.c: Added support for correct handling

	* configure: Modify CheckForBigEndian so it can work in a cross
	compiled situation.

2002-01-16  Frank Warmerdam  <[email protected]>

	* tools/tiffdump.c: include TIFFTAG_JPEGTABLES in tag list.

2002-01-04  Frank Warmerdam  <[email protected]>

	* 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.

2001-12-15  Frank Warmerdam  <[email protected]>

	* 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.

	http://bugzilla.remotesensing.org/show_bug.cgi?id=93
	http://bugzilla.remotesensing.org/show_bug.cgi?id=65

2001-12-12  Frank Warmerdam  <[email protected]>

	http://bugzilla.remotesensing.org/show_bug.cgi?id=90

2001-10-10  Frank Warmerdam  <[email protected]>

	* libtiff/tiff.h: I have created COMPRESSION_CCITT_T4,
	COMPRESSION_CCITT_T6, TIFFTAG_T4OPTIONS and TIFFTAG_T6OPTIONS aliases
	in keeping with TIFF 6.0 standard in tiff.h

	http://bugzilla.remotesensing.org/show_bug.cgi?id=83

	back from TIFFSetField() as an error status, so applications can
	detect failure.

	* libtiff/tif_dir.c: removed the auto replacement of
	COMPRESSION_LZW with COMPRESSION_NONE in _TIFFVSetField().

	* Removed Makefile, tools/Makefile, port/install.sh, man/Makefile
	from CVS as they are all supposed to be auto-generated by configure.

2001-09-22  Frank Warmerdam  <[email protected]>

2001-08-10  Frank Warmerdam  <[email protected]>

	* libtiff/tif_getimage.c: Use memmove() instead of TIFFmemcpy()
	in TIFFReadRGBATile() to avoid issues in cases of overlapping
	buffers.  See Bug 69 in Bugzilla.

	http://bugzilla.remotesensing.org/show_bug.cgi?id=69

	* tools/tiff2rgba.c: fixed getopt() call so that -b works again.

2001-08-09  Frank Warmerdam  <[email protected]>

2001-05-02  Frank Warmerdam  <[email protected]>

	* 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.

	* libtiff/tif_dirwrite.c: Added support for TIFF_VARIABLE2 in the
	case of writing TIFF_BYTE/TIFF_SBYTE fields.

	http://bugzilla.remotesensing.org/show_bug.cgi?id=43

2001-03-29  Frank Warmerdam  <[email protected]>

	* configure, Makefile.in, etc: added support for OPTIMIZER being
	set from config.site.

2001-03-28  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* tif_dirinfo.c: moved definition of copyright tag in field list.
	Apparently they have to be in sorted order by tag id.

2001-03-13  Frank Warmerdam  <[email protected]>

	* tif_getimage.c: Added support for 16bit minisblack/miniswhite
	images in RGBA interface.

2001-03-02  Frank Warmerdam  <[email protected]>

	* Added TIFFTAG_COPYRIGHT support.

2001-02-19  Frank Warmerdam  <[email protected]>

	* 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.

2001-02-16  Frank Warmerdam  <[email protected]>

	* 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
	([email protected]).  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  <[email protected]>

	* 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 <[email protected]>

	* Makefile.in:  Now cleaning up after itself after creating the .tar.gz and .zip

2001-01-07  Frank Warmerdam  <[email protected]>

	  not supported by default.

2000-12-22  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* libtiff/tif_apple.c: Applied "Carbon" support patches supplied by
	Leonard Rosenthol <[email protected]>.  May interfere
	with correct building on older systems.  If so, please let me know.

2000-12-19 Mike Welles <[email protected]>

	* Took out LZW Encoding from tif_lzw.c

	* Created HOWTO-RELEASE

	* Created html/v3.5.6.html

	* updated index.html

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

2000-11-24  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* I have applied a patch from Steffen Moeller <[email protected]> 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>

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>

2000-08-14  Frank Warmerdam  <[email protected]>

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

	Peter Skarpetis <[email protected]>

2000-06-15  Frank Warmerdam  <[email protected]>

	* Modified tiffio.h logic with regard to including windows.h.  It
