Also add a few other entry points +later. + +<li> configure, Makefile.in, etc: added support for OPTIMIZER being + set from config.site. +<li> 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. + +<li> configure/config.site: modified to check if -lm is needed for + MACHDEPLIBS if not supplied by config.site. Needed for Darwin. +<li> libtiff/tiff.h: Applied hac to try and resolve the problem + with the inttypes.h include file on AIX. (Bug 39) + +<li> configure, *Makefile.in: Various changes to improve configuration + for HP/UX specifically, and also in general. (Bug 40) They include: +<ul> + <li> Try to handle /usr/bin/sh instead of /bin/sh where necessary. + <li> Upgrade to HP/UX 10.x+ compiler, linker and dso options. + <li> Fixed mmap() test to avoid MMAP_FIXED ... it isn't available on HP + <li> Use -${MAKEFLAGS} in sub makes from makefiles. + <li> Fixed SCRIPT_SH/SHELL handling. +</ul> +<li> configure: Changes for DSO generation on AIX provided by + John Marquart <jomarqua@indiana.edu>. + +<li> configure, libtiff/Makefile.in: Modified to build DSOs properly + on Darwin thanks to Robert Krajewski (rpk@alum.mit.edu) and + Keisuke Fujii (fujiik@jlcuxf.kek.jp). + +<li> configure, libtiff/Makefile.in: applied OpenBSD patches as per bug 61. + +<li> Makefile.in: added DESTDIR support as per bug 60. + +<li> libtiff/tif_jpeg.c: Define HAVE_BOOLEAN on windows if RPCNDR.H + has been included. +<li> man/Makefile.in: add TIFFClientOpen link as per debian submitted + bug 66. +<li> libtiff/Makefile.in: Fixed @DSOSUB_VERSION to be @DSOSUF_VERSION@ + in two places. +</UL> + +<P><HR WIDTH=65% ALIGN=left> + +<!---------------------------------------------------------------------------> + +<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> + + +<UL> +<li> 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. +<li> tif_luv.c/tiff.h/tiffio.h: + New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward + (greg@shutterfly.com). He writes: + +<ol> + <li> 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. + + <li> 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. + + <li> 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. +</ol> + +<li> libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS. + +<li> Added TIFFTAG_COPYRIGHT support. +<li> tif_getimage.c: Added support for 16bit minisblack/miniswhite + images in RGBA interface. +<li> libtiff/tif_dirinfo.c: removed duplicate TIFFTAG_PHOTOSHOP as per + bug 44. +<li> libtiff/tif_dirwrite.c: Added support for TIFF_VARIABLE2 in the + case of writing TIFF_BYTE/TIFF_SBYTE fields as per bug 43. + +<li> 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. + +<li> libtiff/tif_dirinfo.c: moved pixar and copyright flags to + ensure everything is in order. + +<li> Integrated experimental OJPEG support from Scott Marovich of HP. + +<li> libtiff/tif_open.c: Seek back to zero after failed read, + before writing header. + +<li> libtiff/tiff.h, libtiff/tif_fax3.c: added check for __LP64__ + when checking for 64 bit architectures as per bugzilla bug 67. +<li> libtiff/tif_getimage.c: Use memmove() instead of TIFFmemcpy() + in TIFFReadRGBATile() to avoid issues in cases of overlapping + buffers. See Bug 69 in Bugzilla. +<li> libtiff/tif_getimage.c: Don't complain for CMYK (separated) + images with more than four samples per pixel as per bug 73. + +<li> libtiff/tif_getimage.c: relax handling of contig case where +there are extra samples that are supposed to be ignored as per bug 75. This +should now work for 8bit greyscale or palletted images. + +<li> libtiff/tif_packbits.c: fixed memory overrun error as per bug 77. + +<li> 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. + +<li> 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 as per bug 54. +<li> libtiff/tif_lzw.c: added dummy LZWSetupEncode() to report an + error about LZW not being available. + +<li> libtiff/tif_dir.c: propagate failure to initialize compression + back from TIFFSetField() as an error status, so applications can + detect failure. + +<li> libtiff/tif_lzw.c: Avoid MS VC++ 5.0 optimization bug as per bug 78. + +<li> libtiff/tif_dirwrite.c: added TIFFRewriteDirectory() function. +Updated TIFFWriteDirectory man page to include TIFFRewriteDirectory. + +<li> 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 as per bug 83. + +<li> Added PHOTOMETRIC_ITULAB as per bug 90. + +</UL> + +<P><HR WIDTH=65% ALIGN=left> + +<!--------------------------------------------------------------------------> + +<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A> + +<UL> +<li> 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. +<li> tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by + Bruce A. Mallett, including a faster encoder, fixes for level + 2 PostScript, and support for the imagemask operator. +<li> fax2ps.c: Helge (libtiff at oldach.net) submitted fix +that corrects behaviour for non-Letter paper +sizes. (Bug 35) It fixes two problems: +<br> + 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. +<br> + + Second, scaling now preserves aspect ratio, which makes unusual faxes + (in particular short ones) print properly. + +<li> thumbnail.c: changed default output compression + to packbits from LZW since LZW isn't generally available. +<li> tiff2rgba.c: added -n flag to avoid emitting alpha component. Also added +a man page for tiff2rgba. + +<li> tiffcmp.c: Fixed multi samples per pixel support for ContigCompare +as per bug 53. +Updated bug section of tiffcmp.1 to note tiled file issues. + +<li> libtiff/tif_getimage.c: Fixed so that failure is properly + reported by gtTileContig, gtStripContig, gtTileSeparate and + gtStripSeparate as per bug 51. + + +</UL> + +<P><HR WIDTH=65% ALIGN=left> + +<!---------------------------------------------------------------------------> + +<A NAME="lzwkit"><B><FONT SIZE=+3>C</FONT>HANGES IN THE LZW COMPRESSION KIT:</B></A> +<UL> + <LI> Rewrote lzw patching process so that is required to enable full + LZW support is to drop the tif_lzw.c from the + libtiff-lzw-compression-kit over the one in the libtiff directory. + + <LI> Some changes were made to make recovery from failure to + initialize the LZW compressor more graceful. + + <LI> Note that as distributed libtiff support LZW decompression, but + not LZW compression. +</UL> + +<!---------------------------------------------------------------------------> + +<A NAME="contrib"><B><FONT SIZE=+3>C</FONT>HANGES IN THE CONTRIB AREA:</B></A> +<UL> +<li> Fixed distribution to include contrib/addtiffo/tif_ovrcache.{c,h}. +</UL> + +<A HREF="index.html"><IMG SRC="images/back.gif"></A> TIFF home page.<BR> + +<HR> + +Last updated $Date: 2004-11-26 14:37:20 $. + +</BODY> +</HTML> |
