Also add a few other entry points 473e457fdbSFrank Warmerdamlater. 483e457fdbSFrank Warmerdam 493e457fdbSFrank Warmerdam<li> configure, Makefile.in, etc: added support for OPTIMIZER being 503e457fdbSFrank Warmerdam set from config.site. 513e457fdbSFrank Warmerdam<li> config.guess: updated wholesale to an FSF version apparently 523e457fdbSFrank Warmerdam from 1998 (as opposed to 1994). This is mainly inspired by 533e457fdbSFrank Warmerdam providing for MacOS X support. 543e457fdbSFrank Warmerdam 553e457fdbSFrank Warmerdam<li> configure/config.site: modified to check if -lm is needed for 563e457fdbSFrank Warmerdam MACHDEPLIBS if not supplied by config.site. Needed for Darwin. 573e457fdbSFrank Warmerdam<li> libtiff/tiff.h: Applied hac to try and resolve the problem 583e457fdbSFrank Warmerdam with the inttypes.h include file on AIX. (Bug 39) 593e457fdbSFrank Warmerdam 603e457fdbSFrank Warmerdam<li> configure, *Makefile.in: Various changes to improve configuration 613e457fdbSFrank Warmerdam for HP/UX specifically, and also in general. (Bug 40) They include: 623e457fdbSFrank Warmerdam<ul> 633e457fdbSFrank Warmerdam <li> Try to handle /usr/bin/sh instead of /bin/sh where necessary. 643e457fdbSFrank Warmerdam <li> Upgrade to HP/UX 10.x+ compiler, linker and dso options. 653e457fdbSFrank Warmerdam <li> Fixed mmap() test to avoid MMAP_FIXED ... it isn't available on HP 663e457fdbSFrank Warmerdam <li> Use -${MAKEFLAGS} in sub makes from makefiles. 673e457fdbSFrank Warmerdam <li> Fixed SCRIPT_SH/SHELL handling. 683e457fdbSFrank Warmerdam</ul> 693e457fdbSFrank Warmerdam<li> configure: Changes for DSO generation on AIX provided by 703e457fdbSFrank Warmerdam John Marquart <[email protected]>. 713e457fdbSFrank Warmerdam 723e457fdbSFrank Warmerdam<li> configure, libtiff/Makefile.in: Modified to build DSOs properly 733e457fdbSFrank Warmerdam on Darwin thanks to Robert Krajewski ([email protected]) and 743e457fdbSFrank Warmerdam Keisuke Fujii ([email protected]). 753e457fdbSFrank Warmerdam 763e457fdbSFrank Warmerdam<li> configure, libtiff/Makefile.in: applied OpenBSD patches as per bug 61. 773e457fdbSFrank Warmerdam 783e457fdbSFrank Warmerdam<li> Makefile.in: added DESTDIR support as per bug 60. 793e457fdbSFrank Warmerdam 803e457fdbSFrank Warmerdam<li> libtiff/tif_jpeg.c: Define HAVE_BOOLEAN on windows if RPCNDR.H 813e457fdbSFrank Warmerdam has been included. 823e457fdbSFrank Warmerdam<li> man/Makefile.in: add TIFFClientOpen link as per debian submitted 833e457fdbSFrank Warmerdam bug 66. 843e457fdbSFrank Warmerdam<li> libtiff/Makefile.in: Fixed @DSOSUB_VERSION to be @DSOSUF_VERSION@ 853e457fdbSFrank Warmerdam in two places. 863e457fdbSFrank Warmerdam</UL> 873e457fdbSFrank Warmerdam 883e457fdbSFrank Warmerdam<P><HR WIDTH=65% ALIGN=left> 893e457fdbSFrank Warmerdam 903e457fdbSFrank Warmerdam<!---------------------------------------------------------------------------> 913e457fdbSFrank Warmerdam 923e457fdbSFrank Warmerdam<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> 933e457fdbSFrank Warmerdam 943e457fdbSFrank Warmerdam 953e457fdbSFrank Warmerdam<UL> 963e457fdbSFrank Warmerdam<li> tif_fax3.c: keep rw_mode flag internal to fax3 state to remember 973e457fdbSFrank Warmerdam whether we are encoding or decoding. This is to ensure graceful 983e457fdbSFrank Warmerdam recovery if TIFFClientOpen() discovers an attempt to open a compressed 993e457fdbSFrank Warmerdam file for "r+" access, and subsequently close it, as it resets the 1003e457fdbSFrank Warmerdam tif_mode flag to O_RDONLY in this case to avoid writes, confusing the 1013e457fdbSFrank Warmerdam compressor's concept of whether it is in encode or decode mode. 1023e457fdbSFrank Warmerdam<li> tif_luv.c/tiff.h/tiffio.h: 1033e457fdbSFrank Warmerdam New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward 1043e457fdbSFrank Warmerdam ([email protected]). He writes: 1053e457fdbSFrank Warmerdam 1063e457fdbSFrank Warmerdam<ol> 1073e457fdbSFrank Warmerdam <li> I improved the gamut-mapping function in tif_luv.c for imaginary 1083e457fdbSFrank Warmerdam colors, because some images were being super-saturated on the input 1093e457fdbSFrank Warmerdam side and this resulted in some strange color shifts in the output. 1103e457fdbSFrank Warmerdam 1113e457fdbSFrank Warmerdam <li> I added a psuedotag in tiff.h to control random dithering during 1123e457fdbSFrank Warmerdam LogLuv encoding. This is turned off by default for 32-bit LogLuv and 1133e457fdbSFrank Warmerdam on for 24-bit LogLuv output. Dithering improves the average color 1143e457fdbSFrank Warmerdam accuracy over the image. 1153e457fdbSFrank Warmerdam 1163e457fdbSFrank Warmerdam <li> I added a #define for LOG_LUV_PUBLIC, which is enabled by default in 1173e457fdbSFrank Warmerdam tiffio.h, to expose internal routines for converting between LogLuv and 1183e457fdbSFrank Warmerdam XYZ coordinates. This is helpful for writing more efficient, 1193e457fdbSFrank Warmerdam specialized conversion routines, especially for reading LogLuv files. 1203e457fdbSFrank Warmerdam</ol> 1213e457fdbSFrank Warmerdam 1223e457fdbSFrank Warmerdam<li> libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS. 1233e457fdbSFrank Warmerdam 1243e457fdbSFrank Warmerdam<li> Added TIFFTAG_COPYRIGHT support. 1253e457fdbSFrank Warmerdam<li> tif_getimage.c: Added support for 16bit minisblack/miniswhite 1263e457fdbSFrank Warmerdam images in RGBA interface. 1273e457fdbSFrank Warmerdam<li> libtiff/tif_dirinfo.c: removed duplicate TIFFTAG_PHOTOSHOP as per 1283e457fdbSFrank Warmerdam bug 44. 1293e457fdbSFrank Warmerdam<li> libtiff/tif_dirwrite.c: Added support for TIFF_VARIABLE2 in the 1303e457fdbSFrank Warmerdam case of writing TIFF_BYTE/TIFF_SBYTE fields as per bug 43. 1313e457fdbSFrank Warmerdam 1323e457fdbSFrank Warmerdam<li> libtiff/tif_dirinfo.c: Modified the TIFF_BYTE definition for 1333e457fdbSFrank Warmerdam TIFFTAG_PHOTOSHOP to use a writecount of TIFF_VARIABLE2 (-3) to 1343e457fdbSFrank Warmerdam force use of uint32 counts instead of short counts. 1353e457fdbSFrank Warmerdam 1363e457fdbSFrank Warmerdam<li> libtiff/tif_dirinfo.c: moved pixar and copyright flags to 1373e457fdbSFrank Warmerdam ensure everything is in order. 1383e457fdbSFrank Warmerdam 1393e457fdbSFrank Warmerdam<li> Integrated experimental OJPEG support from Scott Marovich of HP. 1403e457fdbSFrank Warmerdam 1413e457fdbSFrank Warmerdam<li> libtiff/tif_open.c: Seek back to zero after failed read, 1423e457fdbSFrank Warmerdam before writing header. 1433e457fdbSFrank Warmerdam 1443e457fdbSFrank Warmerdam<li> libtiff/tiff.h, libtiff/tif_fax3.c: added check for __LP64__ 1453e457fdbSFrank Warmerdam when checking for 64 bit architectures as per bugzilla bug 67. 1463e457fdbSFrank Warmerdam<li> libtiff/tif_getimage.c: Use memmove() instead of TIFFmemcpy() 1473e457fdbSFrank Warmerdam in TIFFReadRGBATile() to avoid issues in cases of overlapping 1483e457fdbSFrank Warmerdam buffers. See Bug 69 in Bugzilla. 1493e457fdbSFrank Warmerdam<li> libtiff/tif_getimage.c: Don't complain for CMYK (separated) 1503e457fdbSFrank Warmerdam images with more than four samples per pixel as per bug 73. 1513e457fdbSFrank Warmerdam 1523e457fdbSFrank Warmerdam<li> libtiff/tif_getimage.c: relax handling of contig case where 1533e457fdbSFrank Warmerdamthere are extra samples that are supposed to be ignored as per bug 75. This 1543e457fdbSFrank Warmerdamshould now work for 8bit greyscale or palletted images. 1553e457fdbSFrank Warmerdam 1563e457fdbSFrank Warmerdam<li> libtiff/tif_packbits.c: fixed memory overrun error as per bug 77. 1573e457fdbSFrank Warmerdam 1583e457fdbSFrank Warmerdam<li> libtiff/tif_getimage.c: Fixed problem with reading strips or 1593e457fdbSFrank Warmerdamtiles that don't start on a tile boundary. Fix contributed by 1603e457fdbSFrank WarmerdamJosep Vallverdu (from HP), and further described in bug 47. 1613e457fdbSFrank Warmerdam 1623e457fdbSFrank Warmerdam<li> libtif/tif_fax3.c: Removed #ifdef PURIFY logic, and modified to 1633e457fdbSFrank Warmerdam always use the "safe" version, even if there is a very slight 1643e457fdbSFrank Warmerdam cost in performance as per bug 54. 1653e457fdbSFrank Warmerdam<li> libtiff/tif_lzw.c: added dummy LZWSetupEncode() to report an 1663e457fdbSFrank Warmerdam error about LZW not being available. 1673e457fdbSFrank Warmerdam 1683e457fdbSFrank Warmerdam<li> libtiff/tif_dir.c: propagate failure to initialize compression 1693e457fdbSFrank Warmerdam back from TIFFSetField() as an error status, so applications can 1703e457fdbSFrank Warmerdam detect failure. 1713e457fdbSFrank Warmerdam 1723e457fdbSFrank Warmerdam<li> libtiff/tif_lzw.c: Avoid MS VC++ 5.0 optimization bug as per bug 78. 1733e457fdbSFrank Warmerdam 1743e457fdbSFrank Warmerdam<li> libtiff/tif_dirwrite.c: added TIFFRewriteDirectory() function. 1753e457fdbSFrank WarmerdamUpdated TIFFWriteDirectory man page to include TIFFRewriteDirectory. 1763e457fdbSFrank Warmerdam 1773e457fdbSFrank Warmerdam<li> libtiff/tiff.h: I have created COMPRESSION_CCITT_T4, 1783e457fdbSFrank Warmerdam COMPRESSION_CCITT_T6, TIFFTAG_T4OPTIONS and TIFFTAG_T6OPTIONS aliases 1793e457fdbSFrank Warmerdam in keeping with TIFF 6.0 standard in tiff.h as per bug 83. 1803e457fdbSFrank Warmerdam 1813e457fdbSFrank Warmerdam<li> Added PHOTOMETRIC_ITULAB as per bug 90. 1823e457fdbSFrank Warmerdam 1833e457fdbSFrank Warmerdam</UL> 1843e457fdbSFrank Warmerdam 1853e457fdbSFrank Warmerdam<P><HR WIDTH=65% ALIGN=left> 1863e457fdbSFrank Warmerdam 1873e457fdbSFrank Warmerdam<!--------------------------------------------------------------------------> 1883e457fdbSFrank Warmerdam 1893e457fdbSFrank Warmerdam<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A> 1903e457fdbSFrank Warmerdam 1913e457fdbSFrank Warmerdam<UL> 1923e457fdbSFrank Warmerdam<li> Brent Roman contributed updated tiffcp utility (and tiffcp.1) 1933e457fdbSFrank Warmerdam with support for extracting subimages with the ,n syntax, and also 1943e457fdbSFrank Warmerdam adding the -b bias removal flag. 1953e457fdbSFrank Warmerdam<li> tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by 1963e457fdbSFrank Warmerdam Bruce A. Mallett, including a faster encoder, fixes for level 1973e457fdbSFrank Warmerdam 2 PostScript, and support for the imagemask operator. 1983e457fdbSFrank Warmerdam<li> fax2ps.c: Helge (libtiff at oldach.net) submitted fix 1993e457fdbSFrank Warmerdamthat corrects behaviour for non-Letter paper 2003e457fdbSFrank Warmerdamsizes. (Bug 35) It fixes two problems: 2013e457fdbSFrank Warmerdam<br> 2023e457fdbSFrank Warmerdam Without scaling (-S) the fax is now centered on the page size specified 2033e457fdbSFrank Warmerdam with -H and/or -W. Before, fax2ps was using an obscure and practially 2043e457fdbSFrank Warmerdam useless algorithm to allocate the image relative to Letter sized paper 2053e457fdbSFrank Warmerdam which sometime sled to useless whitespace on the paper, while at the 2063e457fdbSFrank Warmerdam same time cutting of the faxes printable area at the opposite border. 2073e457fdbSFrank Warmerdam<br> 2083e457fdbSFrank Warmerdam 2093e457fdbSFrank Warmerdam Second, scaling now preserves aspect ratio, which makes unusual faxes 2103e457fdbSFrank Warmerdam (in particular short ones) print properly. 2113e457fdbSFrank Warmerdam 2123e457fdbSFrank Warmerdam<li> thumbnail.c: changed default output compression 2133e457fdbSFrank Warmerdam to packbits from LZW since LZW isn't generally available. 2143e457fdbSFrank Warmerdam<li> tiff2rgba.c: added -n flag to avoid emitting alpha component. Also added 2153e457fdbSFrank Warmerdama man page for tiff2rgba. 2163e457fdbSFrank Warmerdam 2173e457fdbSFrank Warmerdam<li> tiffcmp.c: Fixed multi samples per pixel support for ContigCompare 2183e457fdbSFrank Warmerdamas per bug 53. 2193e457fdbSFrank WarmerdamUpdated bug section of tiffcmp.1 to note tiled file issues. 2203e457fdbSFrank Warmerdam 2213e457fdbSFrank Warmerdam<li> libtiff/tif_getimage.c: Fixed so that failure is properly 2223e457fdbSFrank Warmerdam reported by gtTileContig, gtStripContig, gtTileSeparate and 2233e457fdbSFrank Warmerdam gtStripSeparate as per bug 51. 2243e457fdbSFrank Warmerdam 2253e457fdbSFrank Warmerdam 2263e457fdbSFrank Warmerdam</UL> 2273e457fdbSFrank Warmerdam 2283e457fdbSFrank Warmerdam<P><HR WIDTH=65% ALIGN=left> 2293e457fdbSFrank Warmerdam 2303e457fdbSFrank Warmerdam<!---------------------------------------------------------------------------> 2313e457fdbSFrank Warmerdam 2323e457fdbSFrank Warmerdam<A NAME="lzwkit"><B><FONT SIZE=+3>C</FONT>HANGES IN THE LZW COMPRESSION KIT:</B></A> 2333e457fdbSFrank Warmerdam<UL> 2343e457fdbSFrank Warmerdam <LI> Rewrote lzw patching process so that is required to enable full 2353e457fdbSFrank Warmerdam LZW support is to drop the tif_lzw.c from the 2363e457fdbSFrank Warmerdam libtiff-lzw-compression-kit over the one in the libtiff directory. 2373e457fdbSFrank Warmerdam 2383e457fdbSFrank Warmerdam <LI> Some changes were made to make recovery from failure to 2393e457fdbSFrank Warmerdam initialize the LZW compressor more graceful. 2403e457fdbSFrank Warmerdam 2413e457fdbSFrank Warmerdam <LI> Note that as distributed libtiff support LZW decompression, but 2423e457fdbSFrank Warmerdam not LZW compression. 2433e457fdbSFrank Warmerdam</UL> 2443e457fdbSFrank Warmerdam 2453e457fdbSFrank Warmerdam<!---------------------------------------------------------------------------> 2463e457fdbSFrank Warmerdam 2473e457fdbSFrank Warmerdam<A NAME="contrib"><B><FONT SIZE=+3>C</FONT>HANGES IN THE CONTRIB AREA:</B></A> 2483e457fdbSFrank Warmerdam<UL> 2493e457fdbSFrank Warmerdam<li> Fixed distribution to include contrib/addtiffo/tif_ovrcache.{c,h}. 2503e457fdbSFrank Warmerdam</UL> 2513e457fdbSFrank Warmerdam 2523e457fdbSFrank Warmerdam<A HREF="index.html"><IMG SRC="images/back.gif"></A> TIFF home page.<BR> 2533e457fdbSFrank Warmerdam 2543e457fdbSFrank Warmerdam<HR> 2553e457fdbSFrank Warmerdam 256*d4dd6cccSBob FriesenhahnLast updated $Date: 2016-09-25 20:05:45 $. 2573e457fdbSFrank Warmerdam 2583e457fdbSFrank Warmerdam</BODY> 2593e457fdbSFrank Warmerdam</HTML> 260
