1994.09.28 21:40 "v3.3beta020 available", by Sam Leffler
I've placed a new version out on sgi.com:~ftp/graphics/tiff. There are many changes for portability to smaller platforms (mainly from S|ren Pingel Dalsgaard <pingel@daimi.aau.dk>) and to larger platforms (the MIPS R8000, a 64-bit machine). I've also added some new functionality, support for the SubIFD tag, that I'm using in my fax software; folks may also encounter this tag if they work with Kodak's new CCD camera. I've made an effort to overhaul the tools so that they have a more consistent command line interface. The manual pages for the tools have been updated, but I've yet to update the man3 section. Still to be done before a "release" is to complete the integration of S|ren's Windows support for machines with segmented architectures and to update the remainder of the documentation. I believe this version is stable and usable (it's exercised regularly through my fax software). Changes include: o update to CHANGES-v3.3 document o optional support for SubIFD tag (for storing thumbnail images); define SUBIFD_SUPPORT when building the library o contrib/fax2ps is updated and should again build o VMS support is updated (though probably again out of date 'cuz of new changes to the library) o numerous changes to libtiff+tools for portability to 64-bit and 16-bit platforms o libtiff now uses _TIFFmalloc, _TIFFrealloc, and _TIFFfree for memory management; this needs to change so that functions are public so that users can pass dynamically allocated memory in to the library (needed for support of segmented architectures) o libtiff now uses _TIFFmemset, _TIFFmemcpy, and _TIFFmemcmp wrappers to hide requirements of machines with segmented architectures o the default error and warning handlers are now system-specific o libtiff has a new TIFFSetSubDirectory interface mainly intended for use with the SubIFD tag o libtiff has a new TIFFUnlinkDirectory interface to unlink the last/current directory created (mainly for my fax software that wants to remove an IFD for a page that's received with unacceptable copy quality) o the Group 3 and Group 4 decoder has been sped up thanks to work by Doug Orr (doug@engin.umich.edu) o TIFFPrintDirectory now prints ASCII strings more carefully: it shows unprintable stuff in C \-style and uses the string length rather than \0-termination to decide what should be printed o libtiff can now append to files written with a byte order opposite to the host platform (not well tested) o tools/thumbnail is a new program that shows one way to use the SubIFD support in the library o most programs in tools now use "-c scheme" to specify a compression scheme to use, "-p config" to specify a planar configuration, and "-f order" to specify a fillorder o all programs in tools should display useful usage messages o tiff2bw now accepts Palette images o lots of tools now have a -o option that can be used to specify a file offset for the starting directory (see the manual pages); this is especially useful for files that use the SubIFD tag As usual there is a patch file (v3.3.0.patch-02) to go from v3.3beta015 and the source distribution (v3.3beta020.src.tar.*). Send bugs to me or the mailing list.
