xref: /libtiff-4.0.7/ChangeLog (revision abcd47ae)

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>

	we are done access data thanks to bug report from:
	Michael Eckstein <[email protected]>.

	* 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__.

2000-05-11  Frank Warmerdam  <warmerda@cs46980-c>

	* README: update to mention www.libtiff.org, don't list Sam's old

	  Jan Van Buggenhout <[email protected]>.

	* libtiff/tif_dirread.c: Don't use estimate strip byte count for
	one tile/strip images with an offset, and byte count of zero. These
	could be "unpopulated" images.

2000-04-18  Frank Warmerdam  <[email protected]>

	* contrib/addtiffo: Added "averaging" resampling option.
