490 a problem with util/gifspnge processing this image, so it will not
491 be added to test-unx yet.
493 1999 05 Mar Michael R Brown <michael@arrakeen.demon.co.uk>
494 * lib/getarg.c: Lines 107 and 189
495 Added ifdef's to use stdarg when available. On dec-alpha the
496 default code was causing programs to crash, probably because
497 it assumes a stack that grows-up.
499 1999 24 Feb Michael R Brown <michael@arrakeen.demon.co.uk>
500 * lib/dgif_lib.c: Lines 363 and 367
501 Bug reported by Steve Sanders, where &'s where causing the
502 memcpy to overwrite the pointers. Fixed by removing the &'s
503 so that memcpy overwrote the memory pointed to.

518 here. FILE_STATE_READ is now 0x08 instead of 0x00.
519 - configure.in: Update version to 4.1.0
520 - lib/Makefile.am: Update libtool version to 5:0:1 (libtool)
521 - giflib.spec: Update for version 4.1.0 (Add libungif-4.1
522 compatibility stuff and change version.)
523 - giflib.lsm: Update for version 4.1.0
524 - lib/egif_lib.c: (WRITE) change from a function to a macro.
525 - lib/dgif_lib.c: (DGifOpenFileName) close FileHandle on error.
526 - lib/dgif_lib.c: (DGifOpenFileHandle) make sure the FILE stream is
527 closed if we hit an error.
528 - lib/dev2gif.c, lib/quantize.c, lib/gif_err.c, lib/gif_lib_private.h:
529 Reflect Eric's copyright notice rather than Gershon's
531 1999 14 Jan Michael R Brown <michael@arrakeen.demon.co.uk>
532 * lib/gif_lib.h: Add OutputFunc type
533 * lib/gif_lib.h: Add EGifOpen for user supplied output function
534 * lib/egif_lib.c: (EGifOpenFileName) Fixed wasted memory when an
535 error occurs in EGifOpenFileHandle
536 * lib/egif_lib.c: Add EGifOpen, WRITE, and lots of changes to
537 support user supplied output function. Basically changing
538 all fwrite's to WRITE, and then all of the knock on effects.
540 1998 17 Dec Toshio Kuratomi <badger@prtr-13.ucsc.edu>
541 * configure.in: Change references to libungif to giflib.
542 * libungif.lsm: Rename to giflib.lsm and change to reflect giflib
543 rather than libungif.
544 * libungif.spec: Rename to giflib.spec and change to reflect giflib
545 rather than libungif.
546 * UNCOMPRESSED_GIF: Removed from this branch.
547 * PATENT_PROBLEMS: Add file explaining Unisys's patent claims.
548 * Makefile.am: Replace libungif with giflib.
549 * README: Adapted language to giflib.
550 * lib/Makefile.am: Changed references to libungif to libgif.
551 * util/Makefile.am: Changed references to libungif to libgif.
553 1998 17 Dec Toshio Kuratomi <badger@prtr-13.ucsc.edu>
554 * lib/egif_lib.c: Merge LZW stuff into this branch of the library.
555 This includes numerous changes to initialize the hash table as well
556 as the code forthe encoder.
557 * lib/gif_hash.c: Functions needed for the LZW encoder.
558 * lib/gif_hash.h: Functions needed for the LZW encoder.
559 * lib/Makefile.am: Add gif_hash.c gif_hash.h to the list of sources.
561 1998 15 Dec Toshio Kuratomi <badger@prtr-13.ucsc.edu>
562 * lib/dgif_lib.c: (DGifSlurp) Fix a Seg Fault when an image contains
565 1998 14 Dec Toshio Kuratomi <badger@prtr-13.ucsc.edu>
566 * configure.in: Update version to 4.0
567 * lib/Makefile.am: Update libtool version to 4:0:0 (libtool)
568 * libungif.spec: Update for version 4.0 (not binary compatible with
569 giflib, change version.)
570 * lib/gif_lib_private.h: (PrivateType) New header for common stuff
571 private to the library. Currently, this is only the Private struct.
572 * lib/dgif_lib.c: (PrivateType) Extract the Private struct to
574 * lib/egif_lib.c: (PrivateType) Extract the Private struct to
576 * lib/Makefile.am: Add gif_lib_private.h to the list of source files.
577 * lib/gif_lib.h: (ExtensionBlock) Add a Function entry to the
578 ExtensionBlock record. Note that this is not entirely correct:
579 the GifLib ExtensionBlock structure is actually a data sub-block
580 record. By adding the function entry here, we are pushing the
581 ExtensionBlockType in with the DataSubBlock.
582 Sometime in the future, we need to change the API to have true
583 ExtensionBlocks which have DataSubBlocks belonging to them.
584 * lib/gif_lib.h: (ExtensionBlock) Deprecate the use of Function in
585 the SavedImage struct. Use ExtensionBlock's Function instead.
586 * lib/egif_lib.c: (EGifSpew) Changes to use the new Function variable.
587 * lib/dgif_lib.c: (DGifSlurp) Changes to put data into the new
590 1998 3 Dec Toshio Kuratomi <badger@prtr-13.ucsc.edu>
591 * lib/dgif_lib.c: (DGifSlurp) Three changes:
592 - No longer allocate SaveImage in this function. All allocations
593 of SaveImage take place in DGifGetImageDesc.
594 - Extension blocks are now associated with the Image Block that is
595 read in subsequent to them, not before. This should now be
596 conformant to the gif89a specification.
597 - Fix an off-by-one error when copying extension data from structure
599 * lib/dgif_lib.c: (DGifGetImageDesc) Change the function to do its own
600 allocation of space for the SavedImage structure no matter what.
601 * lib/egif_lib.c: (EGifSpew) The function now spits out
602 ExtensionBlocks before the associated Image Block to conform with
603 the gif89a specification.
604 * lib/egif_lib.c: (EGifOpenFileHandle) Move the write of the
605 GifVersion (gif87a or gif89a) from this function into
606 EGifPutScreenDesc so that it can be controlled by EGifSpew. Note
607 that this is still a hack as the GifVersion write doesn't really
608 belong in either of these functions.
609 * lib/egif_lib.c: (EGifPutScreenDesc) Moved writing the version
610 (gif87a or gif89a) into the file into this function from
612 * test-unx: Now test the extension code.
613 * pic/x-trans.gif: New image with Comments and transparency to test
614 the extension code with.
616 1998 29 Nov Toshio Kuratomi <badger@prtr-13.ucsc.edu>
617 * lib/dgif_lib.c: (DGifSlurp) Fix a few of the minor bugs plaguing
618 this function. At this point, the function should no longer cause
619 a Seg Fault. It is now losing all extension data however. I know
620 how to hack a fix in, but I need to commit these changes first.
621 * lib/dgif_lib.c: (DGifGetImageDesc) Fix my bug fix: the colormap is
622 now only copied if it exists :-).
624 1998 10 Nov Toshio Kuratomi <badger@prtr-13.ucsc.edu>
625 * test-unx: Add a test for DGifSlurp and EGifSpew
627 1998 14 Oct Toshio Kuratomi <badger@prtr-13.ucsc.edu>
628 * lib/dgif_lib.c: (DGifGetImageDesc) Fix a bug where the Colormap for
629 the image description and the SaveImage were pointers to the same
630 structure, causing a SegV when DGifClosing the file.
632 1998 9 Oct Toshio Kuratomi <badger@prtr-13.ucsc.edu>
633 * lib/dgif_lib.c: (DGifSlurp) memory for the extensions was not being
634 allocated. Now I call AddExtensionBlock when I add an extension to
635 the structure. Additionally, fix a memory leak here.
636 * configure.in, NEWS, lib/Makefile.am: Update to version 3.1.1
637 * ltmain.sh, ltconfig: removed from the cvs repository
638 * BUGS: add the BUGS file to list unresolved BUGS.
640 1998 9 Sep Toshio Kuratomi <badger@prtr-13.ucsc.edu>
641 * libungif.spec: Fix wrong version in %files and %install section.
643 1998 8 Sep Toshio Kuratomi <badger@prtr-13.ucsc.edu>
644 * lib/gif_hash.c, lib/gif_hash.h: Removed these because a hash table
645 is not needed to create uncompressed gifs.
646 * lib/egif_lib.c: Remove all references to the hash functions.
647 * lib/Makefile.am: Remove gif_hash.c gif_hash.h from the source files.
648 * libungif.lsm: added this file
650 1998 7 Sep Toshio Kuratomi <badger@prtr-13.ucsc.edu>
651 * lib/dgif_lib.c, lib/gif_lib.h: (DGifOpen) Add callback to read gif
652 image through user supplied function (Peter Mehlitz).
654 1998 6 Sep Toshio Kuratomi <badger@prtr-13.ucsc.edu>
655 * util/*.{gif.rle}: removed files that were left by my testing
656 process and shouldn't have been in the distribution.
657 * UNCOMPRESSED_GIF: add section on why software that can decode
658 LZW compressed gifs (but not write them) is legal.
659 * .cvsignore: added .cvsignore files to ignore Makefiles and other
660 generated files in my cvs repository.
661 * Makefile.am's: Fixes to allow the dist* family of targets to work
662 correctly. Preliminary support for make check as well.
663 * configure.in: Update version to 3.1.0
664 * lib/Makefile.am: Update libtool version to 4:0:1 libtool)
665 * libungif-3.0.spec: Update from Marc Ewing.
666 * Add int/pointer Alpha fixes from Dick Porter to many source files.
