xref: /libtiff-4.0.7/ChangeLog (revision aefe065e)

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]>

	* html/libtiff.html: Fixed arguments in example for TIFFRGBAImageGet()
	as per bug report by Patrick Connor.

2000-12-28  Frank Warmerdam  <[email protected]>

	* Added RELEASE-DATE file to release file list.

	* Fixed libtiff/makefile.vc to make tiffvers.h not version.h.

2000-12-22  Mike Welles <[email protected]>
        * added link to CVS mirror from index.html

	* updated html/internals.html to note that LZW compression is
	  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

2000-12-01  Frank Warmerdam  <[email protected]>

	* Added patches for EOFB support in tif_fax3.c and tif_fax3.h.
	Patches supplied by Frank Cringle <[email protected]>
	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>

	* tif_dir.c: Clear TIFF_ISTILED flag in TIFFDefaultDirectory
	as per http://bugzilla.remotesensing.org/show_bug.cgi?id=18
	from [email protected].

	* Modified tif_packbits.c decoding to avoid overrunning the
	output buffer, and to issue a warning if data needs to be
	discarded.  See http://bugzilla.remotesensing.org/show_bug.cgi?id=18

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

	* Modified tiff2bw to ensure portions add to 100%, and that
	white is properly recovered.

	See bug http://bugzilla.remotesensing.org/show_bug.cgi?id=15
	Patch c/o Stanislav Brabec <[email protected]>

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>

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

2000-09-25  Frank Warmerdam  <warmerda@cs46980-c>
	* Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
	cygwin compatibility.

	* Applied patch from Roman Shpount to tif_fax3.c.  This seems to
	be a proper fix to the buffer sizing problem.  See
	http://bugzilla.remotesensing.org/show_bug.cgi?id=11

	* Fixed tif_getimage.c to fix overrun bug with YCbCr images without
	downsampling.  http://bugzilla.remotesensing.org/show_bug.cgi?id=10
	Thanks to Nick Lamb <[email protected]> for reporting the
	bug and proving the patch.

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

	* 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  <[email protected]>

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

	* tif_open.c: Set STRIPCHOP_DEFAULT for O_RDWR as well as O_RDONLY
	so that files opened for update can be strip chopped too.

	the strips per separation fix done a few weeks ago.

	* index.html, bugs.html: added bugzilla info.

2000-07-12  Frank Warmerdam  <[email protected]>

	* tif_read.c: fix subtle bug with determining the number of
	rows for strips that are the last strip in a separation but
	not the last strip of all in TIFFReadEncodedStrip().

	* Applied 16/32 bit fix to tif_fax3.c.  Fix supplied by
	Peter Skarpetis <[email protected]>

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

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

	  The original work on all these 2-4GB changes was done by
	  Peter Smith ([email protected]).
