Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=88 2002-04-09 Andrey Kiselev * libtiff/: tif_dirwrite.c, tif_write.c, tiffio.h: TIFFCheckpointDirectory() routine added. Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=124 * man/: TIFFWriteDirectory.3t, Makefile.in: Added description for the new function. 2002-04-08 Andrey Kiselev * 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). * libtiff/tif_getimage.c: The way of codecs checking in TIFFRGBAImageOK 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). * libtiff/: tif_dirinfo.c, tif_dirread.c: Somebody makes a bug in tif_dirread.c when TIFFCreateAnonFieldInfo was introduced. Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=119 in case of _cvs_00000-00.tif, _cvs_00000-01.tif and _cvs_00000-02.tif. 2002-04-04 Andrey Kiselev * libtiff/: tif_lzw.c: Assertions in LZWDecode and LZWDecodeCompat replaced by warnings.

Added PHOTOMETRIC tag value from TIFF technote 4 ICCLAB (=9). 2002-03-26 Andrey Kiselev * 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 * libtiff/: tif_getimage.c: Additional check for supported codecs added in TIFFRGBAImageOK and TIFFReadRGBAImage now uses TIFFRGBAImageOK before reading. Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=110 2002-03-15 Andrey Kiselev * 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 * libtiff/tif_getimage.c: Added support for correct handling `Orientation' tag in gtTileContig. Should be added in other gt* functions as well, but I have not images for testing yet. Partially resolves http://bugzilla.remotesensing.org/show_bug.cgi?id=23 2002-03-10 Andrey Kiselev * libtiff/: tif_dirinfo.c, tif_dirwrite.c: Added possibility to read broken TIFFs with LONG type used for TIFFTAG_COMPRESSION, TIFFTAG_BITSPERSAMPLE, TIFFTAG_PHOTOMETRIC. Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=99 2002-03-08 Andrey Kiselev * libtiff/Makefile.in, tools/Makefile.in: Shared library will not be stripped when installing, utility binaries will do.

Apparently the problem was incorporated since 3.5.5, presumably during the OJPEG/JPEG work recently. 2001-12-15 Frank Warmerdam * 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 * libtiff/tif_jpeg.c: allow jpeg data stream sampling values to override those from tiff directory.

Updated TIFFWriteDirectory man page to include TIFFRewriteDirectory. 2001-09-24 Frank Warmerdam * libtiff/tif_lzw.c: Avoid MS VC++ 5.0 optimization bug. http://bugzilla.remotesensing.org/show_bug.cgi?id=78 * libtiff/tif_lzw.c: added dummy LZWSetupEncode() to report an error about LZW not being available. * libtiff/tif_dir.c: propagate failure to initialize compression 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 * libtiff/tif_ojpeg.c: new update from Scott. 2001-09-09 Frank Warmerdam * libtif/tif_fax3.c: Removed #ifdef PURIFY logic, and modified to always use the "safe" version, even if there is a very slight cost in performance. http://bugzilla.remotesensing.org/show_bug.cgi?id=54 * libtiff/Makefile.in: Fixed @DSOSUB_VERSION to be @DSOSUF_VERSION@ in two places. * libtiff/tif_getimage.c: Fixed problem with reading strips or tiles that don't start on a tile boundary. Fix contributed by Josep Vallverdu (from HP), and further described in bug 47. http://bugzilla.remotesensing.org/show_bug.cgi?id=47 * tools/tiff2ps.c: added OJPEG YCbCr to RGB support. * libtiff/tif_ojpeg.c: Applied substantial patch from Scott. 2001-09-06 Frank Warmerdam * libtiff/tif_packbits.c: fixed memory overrun error. http://bugzilla.remotesensing.org/show_bug.cgi?id=77 2001-08-31 Frank Warmerdam * libtiff/tif_getimage.c: relax handling of contig case where there are extra samples that are supposed to be ignored. This should now work for 8bit greyscale or palletted images. http://bugzilla.remotesensing.org/show_bug.cgi?id=75 2001-08-28 Frank Warmerdam * libtiff/tif_getimage.c: Don't complain for CMYK (separated) images with more than four samples per pixel. See: http://bugzilla.remotesensing.org/show_bug.cgi?id=73 2001-08-10 Frank Warmerdam * 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 * libtiff/tiff.h, libtiff/tif_fax3.c: added check for __LP64__ when checking for 64 bit architectures as per bugzilla bug 67. 2001-07-27 Frank Warmerdam * man/Makefile.in: add TIFFClientOpen link as per debian submitted bug 66. 2001-07-20 Frank Warmerdam * libtiff/tif_jpeg.c: Define HAVE_BOOLEAN on windows if RPCNDR.H has been included. 2001-07-19 Frank Warmerdam * libtiff/tif_open.c: Seek back to zero after failed read, before writing header. 2001-07-18 Frank Warmerdam * libtiff/tif_ojpeg.c: updates from Scott. Handles colors much better. Now depends on having patched libjpeg as per patch in contrib/ojpeg/*. 2001-07-17 Frank Warmerdam * */Makefile.in: added DESTDIR support. http://bugzilla.remotesensing.org/show_bug.cgi?id=60 2001-07-16 Frank Warmerdam * configure, libtiff/Makefile.in: applied OpenBSD patches as per: http://bugzilla.remotesensing.org/show_bug.cgi?id=61 2001-06-28 Frank Warmerdam * libtiff/tif_getimage.c: Fixed so that failure is properly reported by gtTileContig, gtStripContig, gtTileSeparate and gtStripSeparate.

Scott Marovich supplied OJPEG support. 2001-05-11 Frank Warmerdam * tiff.h: removed, it duplicates libtiff/tiff.h. 2001-05-08 Frank Warmerdam * libtiff/tif_dirinfo.c: moved pixar and copyright flags to ensure everything is in order. * libtiff/libtiff.def: added TIFFCreateDirectory and TIFFDefaultStripSize as per: http://bugzilla.remotesensing.org/show_bug.cgi?id=46 2001-05-02 Frank Warmerdam * 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 2001-05-01 Frank Warmerdam * libtiff/tif_dirinfo.c: removed duplicate TIFFTAG_PHOTOSHOP as per bug report http://bugzilla.remotesensing.org/show_bug.cgi?id=44 2001-04-05 Frank Warmerdam * tiffio.h: removed C++ style comment. * configure: fixed up SCRIPT_SH/SHELL handling. * Makefile.in: Fixed SCRIPT_SH/SHELL handling. * config.guess: documented more variables as per bug 40. 2001-04-03 Frank Warmerdam * configure, *Makefile.in: Various changes to improve configuration for HP/UX specifically, and also in general. They include: - Try to handle /usr/bin/sh instead of /bin/sh where necessary. - Upgrade to HP/UX 10.x+ compiler, linker and dso options. - Fixed mmap() test to avoid MMAP_FIXED ... it isn't available on HP - Use -${MAKEFLAGS} in sub makes from makefiles. http://bugzilla.remotesensing.org/show_bug.cgi?id=40 2001-04-02 Frank Warmerdam * libtiff/tiff.h: Applied hac to try and resolve the problem with the inttypes.h include file on AIX. See http://bugzilla.remotesensing.org/show_bug.cgi?id=39 * VERSION: update to 3.5.7 beta in preparation for release. * configure/config.site: modified to check if -lm is needed for MACHDEPLIBS if not supplied by config.site. Needed for Darwin. * config.guess: updated wholesale to an FSF version apparently from 1998 (as opposed to 1994). This is mainly inspired by providing for MacOS X support. 2001-03-29 Frank Warmerdam * configure, Makefile.in, etc: added support for OPTIMIZER being set from config.site. 2001-03-28 Frank Warmerdam * 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 * 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 * 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 * tif_getimage.c: Added support for 16bit minisblack/miniswhite images in RGBA interface. 2001-03-02 Frank Warmerdam * Added TIFFTAG_COPYRIGHT support. 2001-02-19 Frank Warmerdam * 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 * libtiff/libtiff.def: Brent Roman submitted new version adding serveral missing entry points. * libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS. Some sort of weird VMS thing. http://bugzilla.remotesensing.org/show_bug.cgi?id=31 * tif_luv.c/tiff.h/tiffio.h: New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward (greg@shutterfly.com). He writes: 1) I improved the gamut-mapping function in tif_luv.c for imaginary colors, because some images were being super-saturated on the input side and this resulted in some strange color shifts in the output. 2) I added a psuedotag in tiff.h to control random dithering during LogLuv encoding. This is turned off by default for 32-bit LogLuv and on for 24-bit LogLuv output. Dithering improves the average color accuracy over the image. 3) I added a #define for LOG_LUV_PUBLIC, which is enabled by default in tiffio.h, to expose internal routines for converting between LogLuv and XYZ coordinates. This is helpful for writing more efficient, specialized conversion routines, especially for reading LogLuv files. Changes applied with minor edits. 2001-01-23 Frank Warmerdam * 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 * Makefile.in: Now cleaning up after itself after creating the .tar.gz and .zip 2001-01-07 Frank Warmerdam * html/libtiff.html: Fixed arguments in example for TIFFRGBAImageGet() as per bug report by Patrick Connor. 2000-12-28 Frank Warmerdam * Added RELEASE-DATE file to release file list. * Fixed libtiff/makefile.vc to make tiffvers.h not version.h. 2000-12-22 Mike Welles * 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 * 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 * libtiff/tif_apple.c: Applied "Carbon" support patches supplied by Leonard Rosenthol . May interfere with correct building on older systems. If so, please let me know. 2000-12-19 Mike Welles * 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 * Added patches for EOFB support in tif_fax3.c and tif_fax3.h. Patches supplied by Frank Cringle Example file at: ftp://ftp.remotesensing.org/pub/libtiff/eofb_396.tif 2000-11-24 Frank Warmerdam * 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 * I have applied a patch from Steffen Moeller to the configure script so that it now accepts the --prefix, and --exec-prefix directives. 2000-11-13 Frank Warmerdam * 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 * 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 * 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 * tif_dir.c: Clear TIFF_ISTILED flag in TIFFDefaultDirectory as per http://bugzilla.remotesensing.org/show_bug.cgi?id=18 from vandrove@vc.cvut.cz. * Modified tif_packbits.c decoding to avoid overrunning the output buffer, and to issue a warning if data needs to be discarded. See http://bugzilla.remotesensing.org/show_bug.cgi?id=18 2000-10-12 Frank Warmerdam * 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 2000-09-30 Frank Warmerdam * 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 * Added GNULDdso target an`d switched linux and freebsd to use it. 2000-09-26 Frank Warmerdam * Applied patch for 0x0000 sequences in tif_fax3.h's definition of EXPAND1D() as per bug 11 (from Roman). 2000-09-25 Frank Warmerdam * 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 for reporting the bug and proving the patch. 2000-09-18 Frank Warmerdam * Fixed tif_jpeg.c so avoid destroying the decompressor before we are done access data thanks to bug report from: Michael Eckstein . * Reverted tif_flush change. 2000-09-14 Frank Warmerdam * 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 * 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. * tif_read.c: fixed up bug with files missing rowsperstrip and the strips per separation fix done a few weeks ago. 2000-07-17 Frank Warmerdam * Tentatively added support for SAMPLEFORMAT_COMPLEXIEEEFP, and SAMPLEFORMAT_COMPLEXINT. 2000-07-13 Mike Welles * index.html, bugs.html: added bugzilla info. 2000-07-12 Frank Warmerdam * 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 2000-06-15 Frank Warmerdam * Modified tiffio.h logic with regard to including windows.h. It won't include it when building with __CYGWIN__. 2000-05-11 Frank Warmerdam * README: update to mention www.libtiff.org, don't list Sam's old email address. * configure: Fixed DSO test for Linux as per patch from Jan Van Buggenhout . 2000-04-21 Frank Warmerdam * 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 * contrib/addtiffo: Added "averaging" resampling option. * tools/tiffsplit.c: Copy TIFFTAG_SAMPLEFORMAT. Tue Apr 18 16:18:08 2000 Frank Warmerdam * tools/Makefile.in: Modified to install properly on SGI. 2000-04-12 Mike Welles * configure: Fixed stupid mistake in libc6 test on Linux 2000-04-04 Mike Welles * tif_win32.c: Applied patch to fix overreads and ovverwrites caught by BoundsChecker. From Arvan Pritchard (untested). * tif_getimage.c: Applied patch to silence VC6 warnings. From Arvan Pritchard * tif_lzw.c: Applied patch to silence VC6 warnings.

Updated Makefile.in. 2000-03-17 Frank Warmerdam * tif_fax3.c: Fixed serious bug introduced during the uint16->uint32 conversion for the run arrays. 2000-03-03 Frank Warmerdam * Set td_sampleformat default to SAMPLEFORMAT_UINT instead of SAMPLEFORMAT_VOID in TIFFDefaultDirectory() in tif_dir.c. 2000-03-02 Frank Warmerdam * Added "GetDefaulted" support for TIFFTAG_SAMPLEFORMAT in tif_aux.c. * Patched tif_fax3.c so that dsp->runs is allocated a bit bigger to avoid overruns encountered with frle_bug.tif. Tue Feb 15 22:01:05 2000 Frank Warmerdam * Fixed tools/tiffcmp so that stopondiff testing works. Patch care of Joseph Orost . 2000-01-28 * 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.
