272 Thu Sep 20 17:22:48 2001 Owen Taylor <otaylor@redhat.com>
274 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
275 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't
276 work here since we are using the raw file descriptor. So, we call lseek()
277 on the fileno(f) before using it. (#60840).
279 2001-09-20 James Henstridge <james@daa.com.au>
281 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,
282 so that flags types are registered as flags rather than enums (not

287 * Makefile.am (gdk_pixbuf_headers): Don't include
288 gkd-pixbuf-features.h here since is in builddir

333 All of the above from Matthias Clasen <matthiasc@poet.de>,
334 the remaining from Soeren Sandmann <sandmann@daimi.au.dk>.
336 * test-images.h: add tests:
337 - four valid ppm's, eight invalid (matthiasc@poet.de)
338 - one invalid xpm (matthiasc@poet.de)
339 - one valid tga, one invalid (sandmann@daimi.au.dk)
340 - one invalid tiff (sandmann@daimi.au.dk
342 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
344 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
345 fail - detect it when it happens
347 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
350 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
353 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
355 * Makefile.am: don't used BUILT_SOURCES to build marshal
356 files, as in conjunction with stamp files, this can
357 lead to endless rebuilding loops.
359 Tue Sep 4 00:22:07 2001 Owen Taylor <otaylor@redhat.com>
361 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1

402 * pixops/pixops.c: applied some simple but effective optimizations
403 to pixops_composite_nearest() and pixops_composite_color_nearest().
405 2001-08-07 Sven Neumann <sven@gimp.org>
407 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
408 function, so that's what I did.
410 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
412 * gdk-pixdata.c: Fix a typo.

461 * gdk-pixdata.c: <string.h>
463 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
464 also leaking memory here from g_strdup_printf?)
466 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
468 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf

529 Apply patch from sandmann@daimi.au.dk, with some tweaks.
530 Makes things a bit more robust, and adds test-loaders.c
531 which is good for finding further robustness bugs to fix.
533 * io-tiff.c: Try to work around libtiff suckiness a bit;
534 put a giant thread lock on the whole loader,
535 paranoically check both whether error handlers were called and
536 also whether functions return false. Handle case where width or
537 height is 0. Various cleanups.

551 so we don't crash later.
553 * Makefile.am: Add test-loaders
555 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
558 2001-05-29 Darin Adler <darin@eazel.com>
560 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
562 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
564 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
565 fix up bmp decoder to:
566 - adds 16 bpp bmp support (bug #53884)
567 - adds OS/2 1.x format bmp support (bug #54964)
568 - adds 4 bpp RLE compressed bmp support
569 - adds 1 bpp colormap support
570 - fixes negative height (top down) bmp support
572 2001-05-25 Hans Breuer <hans@breuer.org>
574 * gdk_pixbuf.def : reflect Havoc's recent api change
576 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
578 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
581 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
583 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
585 2001-05-04 Havoc Pennington <hp@redhat.com>
587 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
588 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
591 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
592 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
593 confusion of using "src" instead of "p".
594 (pixops_composite_color_nearest): Use a more accurate (and
595 correct, to begin with) compositing method. This cures checks
596 showing through on images with no alpha.
598 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
601 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
603 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
604 area_updated signal to use signed ints. Removed animation-related
607 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
610 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
611 all the pesky details. Remove old frame-based API. Make
612 GdkPixbufAnimation an abstract base class, derived by the loaders.
614 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
616 * Makefile.am (LDADDS): Add $(MATH_LIB).
618 2001-04-18 Havoc Pennington <hp@redhat.com>
620 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
623 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
625 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
626 so we don't try to get <gtk/gtkobject.h> from standard search
629 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
630 add gdk-pixbuf-marshal.list to EXTRA_DIST.
631 take gdk-pixbuf-marshal.h out of _la sources.
633 2001-03-19 Tor Lillqvist <tml@iki.fi>
635 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
637 * gdk_pixbuf.def: Update.
639 * pixbufloader_*.def: Just export the fill_vtable functions now.
641 2001-03-18 Mike Kestner <mkestner@ameritech.net>
643 * make-inline-pixbuf.c (main): Added logic to remove output when
646 2001-03-14 Havoc Pennington <hp@redhat.com>
648 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
649 from gdk-pixbuf-marshal.h, fixes parallel makes.
651 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
653 * test-gdk-pixbuf.c: fixed includes.
655 2001-02-18 Havoc Pennington <hp@pobox.com>
657 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
658 (gdk_pixbuf_get_named_module): prepend underscore
659 (gdk_pixbuf_get_module): prepend underscore
661 2001-02-19 Havoc Pennington <hp@redhat.com>
663 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
665 2001-02-17 Havoc Pennington <hp@pobox.com>
667 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
669 2001-02-07 Alexander Larsson <alexl@redhat.com>
671 * io-xpm.c (free_buffer):
672 Use g_free, since the buffer is allocated with g_try_alloc().
674 2001-02-06 Christophe Merlet <redfox@eikonex.org>
676 * gdk-pixbuf-data.c: Fixes a minor typo.
678 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
680 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
681 we finally need the gobject->gruntime rename.
683 * *.c: scratched calls to g_type_init(), there's simply no point in
684 doing that, use gtk_init().
686 2001-02-01 Havoc Pennington <hp@pobox.com>
688 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
689 in struct to "priv" for C++
691 2001-01-31 Havoc Pennington <hp@pobox.com>
693 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
695 2001-01-26 Havoc Pennington <hp@redhat.com>
697 * gdk-pixbuf-io.c (mname): fix included modules case.
699 2001-01-22 Havoc Pennington <hp@redhat.com>
701 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
702 from gdk_pixbuf_load_module
704 2001-01-22 Havoc Pennington <hp@redhat.com>
706 * Makefile.am: Add built marshaller files to support
707 GdkPixbufLoader signals
709 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
710 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
711 module location, rather than acting as a fallback, because we are
712 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
714 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
716 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
717 from gtk, and add error to close(), because stop_load may do
718 parsing of the image.
720 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
722 * io-*.c: make individual operations static, and add fill_vtable
723 functions which are exported. Fix the collection of type warnings
724 that surfaced, including a number of functions that didn't
725 properly take a GError and some that weren't
726 const-correct. Involved adding error handling for a few loaders.
728 * gdk-pixbuf-io.h: Add error reporting to stop_load function
730 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
731 a function that fills in the GdkPixbufModule vtable, instead of
732 looking up all the image functions individually; this means we
733 can get type safety within modules for the loader functions.
734 Also it means you don't have to keep the statically compiled and
735 GModule versions in sync.
737 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
739 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
741 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
743 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
746 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
748 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
751 2001-01-20 John Harper <jsh@eazel.com>
753 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
754 collision between Xlib's RdBitF.c and io-tiff.c
756 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
759 [ merged from stable gdk-pixbuf module. Untested, but it
760 compiles, and works fine in the stable module ]
762 2001-01-18 Tor Lillqvist <tml@iki.fi>
764 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
765 g_win32_get_package_installation_subdirectory() function. No need
766 to include windows.h.
767 (gtk_win32_get_installation_directory): Remove this then.
769 2001-01-01 Havoc Pennington <hp@redhat.com>
771 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
772 @LIBTOOL_EXPORT_OPTIONS@
774 2000-12-30 Tor Lillqvist <tml@iki.fi>
776 * gdk_pixbuf.def: Update.
778 2000-12-16 Havoc Pennington <hp@pobox.com>
780 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
781 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
782 (gdk_pixbuf_frame_copy): new function
783 (gdk_pixbuf_frame_free): new function
784 (gdk_pixbuf_frame_get_type): new function
785 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
787 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
789 * Makefile.am: Add -avoid-version for all modules.
791 2000-11-13 Havoc Pennington <hp@redhat.com>
793 * io-png.c (png_simple_error_callback): fix error message to not
794 say "save" since it's used for loading
796 2000-11-11 Hans Breuer <Hans@Breuer.Org>
798 * gdk-pixbuf-io.c : Fix all function prototype macros for self
799 contained image handlers (!USE_G_MODULE). Files to save should
800 be opened in binary mode, fopen(s, "wb").
802 * io-xpm.c : added HAVE_UNISTD_H condition
804 2000-11-11 Tor Lillqvist <tml@iki.fi>
806 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
808 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
809 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
810 mktemp() and open()).
812 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
814 2000-11-01 Havoc Pennington <hp@pobox.com>
816 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
817 a pixbuf pointing to a subregion of another pixbuf.
819 2000-10-16 Tor Lillqvist <tml@iki.fi>
821 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
823 2000-10-16 Havoc Pennington <hp@redhat.com>
825 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
826 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
827 add error reporting here also
829 * make-inline-pixbuf.c (main): use GError
831 * io-xpm.c: include unistd.h
833 * gdk-pixbuf-util.c: include string.h
835 * io-*.c: add error reporting
837 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
840 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
842 * gdk-pixbuf-io.h: Add GError** to load_increment and load
845 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
846 a G_FILE_ERROR if we fail to write or close the file.
848 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
849 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
850 the GError naming rules. Add GError** to load functions.
852 2000-10-06 Havoc Pennington <hp@redhat.com>
854 * gdk-pixbuf.h: add GdkPixbufAlphaMode
856 2000-10-06 Havoc Pennington <hp@redhat.com>

884 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
886 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
887 last nights code was still "broken". Should now properly handle
888 all error conditions gracefully.
890 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
892 * gdk-pixbuf/io-pnm.c: Rewrote.

914 2000-07-21 Larry Ewing <lewing@helixcode.com>
916 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
917 xpm at least supports the progressive interface like the one in
918 io-tiff.c. This should be reimplemented as an actual progressive
921 2000-07-19 Jonathan Blandford <jrb@redhat.com>
923 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
925 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
926 meeks to handle errors better.
928 2000-10-07 Tor Lillqvist <tml@iki.fi>

939 consistent with gdk_pixbuf_loader_new_with_type().
940 Return runtime error if a module is missing.
942 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
944 2000-10-05 Havoc Pennington <hp@redhat.com>
946 Pixbuf saving, patch from David Welton.
948 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS

968 2000-10-05 Dan Winship <danw@helixcode.com>
970 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
971 all three of these files are the JPEG image loader. (From
974 2000-10-03 Tor Lillqvist <tml@iki.fi>
976 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
977 gdk-pixbuf's version number in the rule for makefile.mingw itself.
979 * gdk_pixbuf.def: Add new entry points.
981 2000-09-26 Havoc Pennington <hp@redhat.com>
983 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
984 function here, instead of putting it in a private GTK+ file.
986 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
987 enum here for the known formats of inlined pixbufs.
988 Also, #define our file magic here.
990 2000-06-23 Havoc Pennington <hp@redhat.com>
992 * make-inline-pixbuf.c: Small program that creates C variable
993 declarations of inline pixbuf data. This can be read
994 by gdk_pixbuf_new_from_inline.
996 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
997 inline pixbuf data and create a pixbuf from it.
999 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
1001 2000-09-07 Tor Lillqvist <tml@iki.fi>
1003 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
1006 2000-08-12 Tor Lillqvist <tml@iki.fi>
1008 * gdk_pixbuf.def: Add missing entry point.
1010 2000-08-10 Havoc Pennington <hp@redhat.com>
1012 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
1013 (s/pixbuf_/pixbufloader_)
1015 2000-08-02 Tor Lillqvist <tml@iki.fi>
1021 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1023 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1024 one. Fix names of DLLs to have '-' instead of '_'.
1026 2000-07-31 Elliot Lee <sopwith@redhat.com>
1027 * io-wbmp.c: Some bug fixes - now tested to work.
1029 2000-07-27 Elliot Lee <sopwith@redhat.com>
1031 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1032 gdk_pixbuf_get_named_module() function to facilitate above change
1033 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1034 Implement loader for WBMP format.
1035 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1037 2000-07-23 Tor Lillqvist <tml@iki.fi>
1042 * pixops/makefile.mingw.in
1043 * pixbuf_*.def: New files.
1046 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1048 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1049 New function, to get the GTK+ installation directory from
1050 the Windows Registry, where the installation program
1051 for whatever software includes GTK+ has stored it.
1053 Used to avoid having hardcoding the directory where to look for
1054 loaders. This function is needed by gtk, too, so it should
1055 really be just in one place. Maybe a small static library
1056 one level up from here?
1058 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1059 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1060 Open file in binary mode. This *is* standard C. (No-op on Unix,
1063 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1065 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1066 mktemp() and open().
1067 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1069 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1070 pseudo-op. Conditionalise on __MINGW32__, but probably
1071 should conditionalise on Gas version instead? Or could we
1072 do without .type on all systems?
1074 * pixops/timescale.c: Use g_get_current_time()
1075 instead of gettimeofday().
1077 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1079 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1081 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1083 * gdk-pixbuf.c: Add <string.h> include.
1085 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1087 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1088 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1089 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1090 use g_object_new() instead of g_type_create_instance() which
1091 is a private function for fundamental type implementations.
1093 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1095 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1096 soname scheme for gdk-pixbuf.
1098 2000-06-21 Havoc Pennington <hp@pobox.com>
1100 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1101 (i.e. derivation is not allowed, and there are no virtual methods
1103 (gdk_pixbuf_preinit): Call g_type_init() here.
1104 (gdk_pixbuf_init): Add a user-friendly init function, for users
1105 of standalone gdk-pixbuf
1107 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1108 way GdkPixbufAnimation was done.
1110 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1111 gdk_pixbuf_finalize() from API, since these are broken and don't
1112 make sense with new GObject stuff.
1114 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1116 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1117 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1120 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1122 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1123 so I needed something to warm my thighs. Running plain infinite
1124 loops on your laptop to make it hot is not very much fun. A demo
1125 of the gdk-pixbuf scaling functions is way better, and looks
1128 * configure.in (AC_OUTPUT): Added the demo Makefile.
1130 * Makefile.am (SUBDIRS): Added the demo directory.
1132 2000-06-09 Larry Ewing <lewing@helixcode.com>
1134 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1135 setjmp for the png error handler. It seems setting the error
1136 handling functions does not avoid the jump, and so not calling
1137 setjmp was causing the incremental loader to jump into lala land.
1138 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1139 not sure this one is actually required but the docs say it must be
1140 set for every call to a png_* function.
1141 Also changed the comment to reflect the fact that setting the
1142 error handlers does _not_ avoid the longjmp.
1144 2000-06-06 Larry Ewing <lewing@helixcode.com>
1146 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1147 take frame offest into account when trying to calculate the
1148 animation bbox. Also set the width to the width not the height.
1149 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1150 calculate bbox because now we finally have all the offset
1151 information for each frame.
1153 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
1155 * configure.in: add some gtk parameters to the
1156 GDK_PIXBUF_LIB²S and GDK_PIXBUG_INCLUDEDIR vars. One more
1157 fight in my crusade for strange prefix compile...
1159 2000-05-30 Not Zed <NotZed@HelixCode.com>
1161 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
1162 Initialise the error handler exit routine to our own. Note this
1163 means that every function that accesses the jpeg lib on this
1164 object MUST do a setjmp.
1165 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
1166 lib for handling fatal error.
1167 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
1168 your applications dont quit if there's a jpeg error!
1170 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
1172 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
1173 from Frank de Lange <frank@unternet.org>.
1175 2000-05-09 Darin Adler <darin@eazel.com>
1177 * gdk-pixbuf/test-gdk-pixbuf.c:
1178 Fixed includes to get rid of accidental GNOME dependency.
1180 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
1181 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
1183 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
1185 * configure.in: Bumped version number to 0.8.0.
1187 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
1188 file was not being distributed.
1190 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
1192 2000-05-09 Darin Adler <darin@eazel.com>
1194 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
1195 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
1196 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
1197 formats to 32-bit formats to re-use the high bits of the color values
1198 so that white maps to full white.
1200 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
1202 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
1203 detailed information about the structure and algorithms
1204 of pixops so people can fix it instead of breaking it.
1206 2000-05-04 Darin Adler <darin@eazel.com>
1208 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
1209 (composite_pixel), (composite_line):
1210 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
1211 Now that Owen explained the algorithm, I think I implemented it
1212 right for the cases where the destination pixbuf is not opaque.
1213 The test does seem to confirm it.
1215 2000-05-04 Darin Adler <darin@eazel.com>
1217 * gdk-pixbuf/.cvsignore:
1218 * gdk-pixbuf/Makefile.am:
1219 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
1220 (load_pixel), (simple_composite_test_one),
1221 (simple_composite_test_one_type), (simple_composite_test), (main):
1222 Added some tests of composite to highlight problems in the old
1223 implementation. These tests run without any user interaction.
1224 Just do "make check".
1226 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
1227 (composite_pixel), (composite_line): Fix composite to do a textbook
1228 "A over B" composite. This was clearly the intent, and it was easy
1229 to fix the code to do it. (Note to those that read my earlier tries
1230 at a patch; this version fixes typos that were present in all
1231 my patch attempts. I checked the final version by adding more tests.)
1233 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
1235 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
1236 offset y coordinate accordining to render_y0.
1238 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
1241 2000-04-22 James Henstridge <james@daa.com.au>
1243 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
1244 package to the devel package. The only file installed in bin is
1245 gdk-pixbuf-config, which belongs in -devel. This should allow having
1246 multiple versions of the main gdk-pixbuf package installed.
1248 2000-04-17 Karl Eichwalder <ke@suse.de>
1250 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
1251 Reported by Jens Finke.
1253 2000-04-14 Tomasz K³opczko <kloczek@pld.org.pl>
1255 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
1256 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
1258 2000-04-13 James Henstridge <james@daa.com.au>
1260 * configure.in: when performing the configure check to see if
1261 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
1262 rather than the other way round. Also, call AC_MSG_RESULT in the
1263 even that dynamic modules were not supported.
1265 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
1267 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
1268 hook to the last unref operation.
1270 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
1271 function to set the last unref handler for a pixbuf.
1272 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
1273 It calls the pixbuf's destroy notification function and frees the
1274 GdkPixbuf structure itself.
1275 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
1278 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
1279 for the last unref handler and its user data.
1281 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
1282 g_new0() to allocate the pixbuf.
1284 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
1285 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
1286 was not specifying the `frame' argument.
1288 * gdk-pixbuf/gdk-pixbuf-animation.c
1289 (gdk_pixbuf_animation_get_width): Fixed docstring.
1290 (gdk_pixbuf_animation_get_height): Likewise.
1291 (gdk_pixbuf_animation_get_num_frames): Likewise.
1292 (gdk_pixbuf_animation_get_frames): Likewise.
1294 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
1297 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
1299 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
1301 * doc/tmpl/refcounting.sgml: Updated with the information about
1302 the last unref handler.
1304 * doc/tmpl/*.sgml: Markup tweaks.
1306 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
1307 update the libtool version number for libgnomecanvaspixbuf as
1309 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
1310 as well, or the old ones won't work with the new stuff. Also,
1311 renamed the modules as follows.
1313 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
1314 modules are called "libpixbufloader-<format>.so" instead of
1315 "libpixbuf-<format>.so". They needed renaming so that the new
1316 loaders won't overwrite the old ones; even with the versioning
1317 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
1320 2000-04-12 Paolo Molaro <lupus@debian.org>
1322 * .cvsignore, src/.cvsignore: shut up cvs.
1324 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
1326 Most of this patch is based on a patch by Havoc Pennington
1327 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
1328 remove the libart dependency.
1330 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
1331 (GdkColorspace): New enum that for now only contains
1333 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
1334 notification function.
1335 (GdkInterpType): New num with interpolation types.
1337 * *.[ch]: Replace the libart stuff with our own stuff.
1339 * pixops/*.[ch]: Likewise.
1341 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
1342 declarations of the GdkPixbuf structures.

1358 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
1359 bits_per_sample argument; currently only 8 bits per sample are
1362 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
1364 (gdk_pixbuf_frame_get_x_offset): New accessor.
1365 (gdk_pixbuf_frame_get_y_offset): New accessor.
1366 (gdk_pixbuf_frame_get_delay_time): New accessor.
1367 (gdk_pixbuf_frame_get_action): New accessor.
1369 * gdk-pixbuf/gdk-pixbuf-render.c
1370 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
1371 mask rectangle for pixbufs without an alpha channel, set the
1372 *mask_return to NULL.
1374 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
1376 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
1378 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
1379 preconditions. Maybe we should also check for the colorspace,
1380 bits per pixel, and such.
1381 (gdk_pixbuf_composite): Likewise.
1382 (gdk_pixbuf_composite_color): Likewise.
1383 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
1384 cannot allocate the new pixbuf.
1385 (gdk_pixbuf_composite_color_simple): Likewise.
1387 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
1388 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
1391 * gdk-pixbuf/io-bmp.c: Fix includes.
1393 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
1398 * configure.in: Removed checks for libart.
1400 * gdk-pixbuf/Makefile.am: Removed references to libart.
1401 (noinst_HEADERS): Added gdk-pixbuf-private.h.
1403 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
1404 the version number of the libtool library to indicate that this
1405 definitely is not compatible with the old usage. I know you love
1408 * configure.in: Bumped version number to 0.7.0.
1412 * gdk-pixbuf-config.in (--libs): We no longer require libart.
1414 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
1416 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.

1420 * gdk-pixbuf/testanimation.c (main): add more info to the
1421 testanimation frames.

1431 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
1433 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
1434 is private information, and the art_pixbuf will go away soon.
1436 2000-03-31 Mark Crichton <crichton@gimp.org>
1438 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
1439 and gdk_pixbuf_get_artpixbuf accessor functions.
1441 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
1443 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
1444 gboolean instead of int.
1446 2000-03-29 Radek Doulik <rodo@helixcode.com>
1448 * gdk-pixbuf/gdk-pixbuf-animation.c
1449 (gdk_pixbuf_animation_new_from_file): same as below
1451 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and

1454 2000-03-28 Radek Doulik <rodo@helixcode.com>
1456 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
1457 context->frame_done_func and context->anim_done_func to make
1458 progressive animation loading work
1460 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1461 added priv->pixbuf = NULL as pixbuf is now in frame (and to make

1463 (gdk_pixbuf_loader_frame_done): update animation bbox
1465 * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to
1468 2000-03-27 Radek Doulik <rodo@helixcode.com>
1470 * gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width
1471 instead of width and height
1473 2000-03-27 Owen Taylor <otaylor@redhat.com>
1475 * gdk-pixbuf/pixops/pixops.c: Fix problem with
1476 precendence of >> and & which was keeping composite_color
1477 from working with non-gray images.
1479 2000-03-08 Jonathan Blandford <jrb@redhat.com>
1481 * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context.
1482 (gdk_pixbuf__gif_image_load_animation): free the context.
1484 2000-03-06 Arjan van de Ven <arjan@fenrus.demon.nl>
1486 * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a
1487 mis-interpretation of the Microsoft documentation. Now
1488 it can load .BMP files that are not generated by The Gimp
1491 2000-03-01 Mark Crichton <crichton@gimp.org>
1493 * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
1494 fix the last auto* build bug (where we have libart, but no
1497 * gdk-pixbuf/Makefile.am: Same.
1499 2000-02-28 Matt Wilson <msw@redhat.com>
1501 * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,
1502 s/unsigned short/guint16/g, s/unsigned char/guint8/g
1504 2000-02-26 Federico Mena Quintero <federico@helixcode.com>
1506 * README: We don't require libgif/ungif nor libXpm.
1508 * NEWS: This was outdated, so updated it.
1510 2000-02-25 Federico Mena Quintero <federico@helixcode.com>
1512 * gdk-pixbuf.m4: Use the correct name for
1513 gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing
1516 2000-02-21 Federico Mena Quintero <federico@helixcode.com>
1518 * configure.in (GDK_PIXBUF_MINOR): Bumped version number to 0.6.0.
1520 * doc/compiling.sgml: New appendix documenting the gdk-pixbuf
1521 library's particular options to configure.in.
1523 * doc/gdk-pixbuf.sgml: Include compiling.sgml appendix via an
1526 * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml.
1528 * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment):
1529 Fixed typo in prototype name.
1531 * configure.in: Changed duplicated AC_MSG_CHECKING message to
1532 something more meaningful; now it is "checking whether dynamic
1535 * gdk-pixbuf/pixops/Makefile.am (noinst_PROGRAMS): Do not install
1536 the timescale program.

1598 prefix for the modules to load the information.
1600 * configure.in (GDK_PIXBUF_VERSION): New option --disable-modules
1601 lets the user specify that gdk-pixbuf should link all image loader
1602 code into the library instaed of creating shared library modules.

1903 * gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference

1905 copy of an animated GIF if it appears multiple times in a web
1908 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
1909 animation functions here.
1910 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
1911 animation if the loader does not support multiframe loading and
1912 the single-frame load returned NULL. Check that the filename is
1913 not NULL. Updated inline documentation.
1914 (gdk_pixbuf_animation_ref): New function.
1915 (gdk_pixbuf_animation_unref): New function.
1916 Removed gdk_pixbuf_animation_destroy() in favor of reference

1924 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
1927 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
1928 with a reference count of 1.
1930 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
1931 gdk-pixbuf-animation.c.
1933 * doc/tmpl/animation.sgml: Populated. It is still missing a
1934 description of the overlay modes.

1950 1999-12-23 Havoc Pennington <hp@pobox.com>
1952 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
1953 set to NULL here (specifically context->animation) was not being
1954 set to NULL. use g_new0() to alloc the struct.
1956 1999-12-20 Jonathan Blandford <jrb@redhat.com>
1958 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
1959 correctly. Progressive loading needs some work, but that all
1960 needs doing from the gdk-pixbuf-loader end, not here.
1962 1999-12-17 Jonathan Blandford <jrb@redhat.com>
1964 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
1965 moved the file here. It seems natural to put this function here,
1966 as that's where the gdk_pixbuf_new_from_file function is, but it's
1967 still a little convoluted. The source files might be played with
1970 1999-12-14 Jonathan Blandford <jrb@redhat.com>
1972 * gdk-pixbuf/gdk-pixbuf-loader.c
1973 (gdk_pixbuf_loader_get_animation): Gets the animation from the

1984 * gdk-pixbuf/gnome-canvas-pixbuf.c
1985 (gnome_canvas_pixbuf_class_init): Renamed arguments to
1986 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for

2016 Filled in body of function.
2017 (rgbconvert): Added GdkColormap parameter, and to all conversion
2019 (convert_real_slow): New function - should convert ANY visual/data
2020 format properly, but it aint fast. Used as a fallback when an
2021 optimised routine wont match.
2022 (rgbconvert): Do very specific tests on the data format to verify
2023 properly if the optimised version will do, otherwise use the
2024 fallback function for all other data formats.
2026 * gdk-pixbuf/Makefile.am: Re-enabled building of
2027 textpixbuf-drawable.
2029 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
2030 gdk_pixbuf_get_from_drawable().
2032 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
2034 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red

2041 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
2042 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2043 checks and API definition. The body needs filling in and it needs
2044 to do the Right Thing(tm) for pixmaps plus the given colormap and
2045 windows and their own colormaps.
2047 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2048 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
2050 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.

2085 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2086 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2087 want, send me a patch to do the conditional stuff properly.
2088 Otherwise, please read the GNOME Programming Guidelines,
2089 especially the "CVS policies" section.
2091 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>

2184 since it is not finished.
2186 * src/gdk-pixbuf.h: Removed unused transformation prototypes.
2188 * src/gdk-pixbuf-util.c: New file with utility and convenience
2189 functions for pixbufs.
2191 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-util.c.
2193 * doc/gdk-pixbuf-sections.txt: Added section for utility functions.
2195 * doc/Makefile.am (tmpl_sources): Added tmpl/util.sgml.
2197 * doc/gdk-pixbuf.sgml: Added the utilities section.
2199 * doc/tmpl/util.sgml: Documentation for the utility functions.
2201 1999-11-29 Owen Taylor <otaylor@redhat.com>
2203 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
2204 Keep the mask around until after we draw ... since
2205 the GC changes aren't flushed to the X server until we
2206 draw, destroying it before that may result in BadPixmap
2209 1999-11-30 Havoc Pennington <hp@pobox.com>
2211 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
2213 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
2215 1999-11-29 Federico Mena Quintero <federico@redhat.com>
2217 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
2218 should be made conditional, not blindly commented out.
2220 1999-11-29 Jonathan Blandford <jrb@redhat.com>
2222 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
2223 handle .ico files. Cool.
2225 1999-11-24 Jonathan Blandford <jrb@redhat.com>
2227 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
2230 1999-11-24 James Henstridge <james@daa.com.au>
2232 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
2233 top builddir rather than src. This still builds fine, and does not
2234 get gtk-doc into an infinite loop when trying to find all the source
2237 1999-11-23 Jonathan Blandford <jrb@redhat.com>
2239 * Removed #PRAGMA } from headers. Also, make compile if you don't
2240 have it installed, already.
2242 1999-11-22 Federico Mena Quintero <federico@redhat.com>
2244 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
2245 temporary buffer to the size of the interesction of the bounding
2246 box and the expose area, not the whole expose area. This speeds
2249 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
2250 not paint black on the mask, since we already cleared it in a
2251 single gdk_draw_rectangle() operation.
2253 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
2255 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
2257 1999-11-22 Havoc Pennington <hp@pobox.com>
2259 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
2260 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
2261 dependencies to LIBADD variables for loadable modules. Necessary
2262 for a Java dynamic loading thing to be able to figure it out.
2264 1999-11-22 Havoc Pennington <hp@pobox.com>
2266 * src/io-png.c (image_load_increment): Call the update_area
2267 callback depending on the number of rows loaded in this increment.
2269 * src/testpixbuf.c (main): slow down the progressive load demo
2271 1999-11-16 Havoc Pennington <hp@pobox.com>
2273 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
2275 1999-11-22 Jonathan Blandford <jrb@redhat.com>
2277 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
2278 for srcdir != buildir != . Beats me why; I can't figure it out.
2279 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
2281 1999-11-21 Jonathan Blandford <jrb@redhat.com>
2283 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
2284 <arjan@fenrus.demon.nl>
2286 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2288 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
2289 Rework/reorder of the code. Each case has been separated into
2290 another function; its big but it should be quick.
2291 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
2292 opaque alpha information. Not all depths/formats have been
2293 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
2295 1999-11-17 Larry Ewing <lewing@gimp.org>
2297 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
2298 implement the bounds method correctly.
2299 (compute_viewport_affine): compute the affine need to fit the
2300 image within the viewport given by the args.
2301 (compute_render_affine): call compute_viewport_affine.
2303 1999-11-16 Havoc Pennington <hp@pobox.com>
2305 * src/gdk-pixbuf-drawable.h: Use includes from the current
2306 directory, not the system directory.
2308 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
2310 * src/testpixbuf-drawable.c: use includes from the current directory
2311 rather then from the system include directory as gdk-pixbuf
2312 includes are not yet installed when this is compiled.
2314 1999-11-13 Cody Russell <bratsche@dfw.net>
2315 * src/testpixbuf-drawable.c: Added a test program for drawable
2318 * src/Makefile.am: Build testpixbuf-drawable.
2320 1999-11-12 Cody Russell <bratsche@dfw.net>
2322 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.
2324 1999-11-10 Federico Mena Quintero <federico@redhat.com>
2326 * doc/tmpl/gdk-pixbuf-loader.sgml: Populated.
2328 * doc/gdk-pixbuf.signals: Put in the real names of signal
2331 * src/gdk-pixbuf-loader.c: Improved documentation comments.
2333 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2335 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
2338 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
2339 correctly. Patch from Arjan to do so.
2341 1999-11-10 Michael Fulbright <drmike@redhat.com>
2343 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
2346 * src/testpixbuf.c: Added final queued draw when done loading image.
2348 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2350 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
2353 1999-11-10 Federico Mena Quintero <federico@redhat.com>
2355 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
2358 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2360 * src/io-png.c: Fixed some incompatible pointer initializations.
2362 * src/io-jpeg.c (image_load_increment): Remove unused variable.
2364 1999-11-09 Michael Fulbright <drmike@redhat.com>
2366 * src/testpixbuf.c: Fixed it to use timeout to read from file
2367 for progressive loading. Set TBF_KBPS=n, where n is the number of
2368 kilobytes/second to simulate in downloading. n has to be an integer.
2370 * src/io-jpeg.c: Slight cosmetic cleanup.
2372 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
2373 PBM loading has a similar problem and will address tomorrow.
2375 1999-11-09 Havoc Pennington <hp@pobox.com>
2377 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
2378 gdk-pixbuf-drawable stuff.
2380 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2382 * configure.in: Bumped version number to 0.4.
2384 1999-11-09 Michael Fulbright <drmike@redhat.com>
2386 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
2387 all types of PNM files now.
2389 * src/io-jpeg.c (image_load_increment): Figured out problem with
2390 loading Progressive JPEG's progressively (say that 10 times fast).
2391 Currently for Progressive JPEG's the entire image is loaded before
2392 it is displayed. libjpeg supports a fancier mechanism which I may
2395 With these changes all JPEG formats appear to load properly for me.
2397 1999-11-08 Jonathan Blandford <jrb@redhat.com>
2399 * src/io-ras.c (image_load_increment): Final patch from Arjan.
2400 Seems to do progressive loading.
2402 1999-11-08 Michael Fulbright <drmike@redhat.com>
2404 * src/io-pnm.c image_load (): Fixed so we do not create a separate
2405 pixel buffer when reading in image - we reuse the pixel data in
2406 the GdkPixbuf structure instead.
2408 1999-11-08 Michael Fulbright <drmike@redhat.com>
2410 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
2411 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
2412 I can't seem to find a utility to convert into this format.
2413 Next is to add progressive loading support for the PNM format.
2415 1999-11-07 Federico Mena Quintero <federico@redhat.com>
2417 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
2418 of the width, height, x, and y setting and pixels arguments.
2420 1999-11-05 Jonathan Blandford <jrb@redhat.com>
2422 * src/io-ras.c (image_load): third patch. Now it seems to load.
2424 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
2425 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
2427 * src/io-ras.c (image_load): new file from Arjan van de Ven
2428 <arjan@fenrus.demon.nl> to begin the ras loader.
2430 1999-11-05 Federico Mena Quintero <federico@redhat.com>
2432 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
2433 for internal use only.
2435 * doc/gdk-pixbuf.sgml: Likewise.
2437 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
2439 1999-11-05 Michael Fulbright <drmike@redhat.com>
2441 * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
2442 files from a file. Next step is support for ASCII files, and
2443 then incremental loading.
2445 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2447 * Makefile.am: Added doc to SUBDIRS.
2449 1999-11-04 Michael Fulbright <drmike@redhat.com>
2451 * src/io-jpeg.c: Prettied up code slightly.
2452 * src/io-pnm.c: Start of pnm loader (from file and progressively).
2453 Doesn't do much yet (will finish tomorrow).
2454 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
2456 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2458 * doc/tmpl/rendering.sgml: Populated.
2460 * doc/Makefile.am: Added the template files.
2462 1999-11-04 Havoc Pennington <hp@pobox.com>
2464 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
2465 docs, explain what a dither offset is for.
2466 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
2467 this function vs. gdk_pixbuf_render_to_drawable().
2469 1999-11-04 Havoc Pennington <hp@pobox.com>
2471 * configure.in: Use libart-config correctly; find gnome-config
2472 separately. Fix GNOME_LIBS to be correct in "no gnome installed
2475 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
2478 Patch untested in the inside-gnome-libs case, I need to commit
2479 then check out to the gnome-libs I'm using.
2481 1999-11-04 Michael Fulbright <drmike@redhat.com>
2483 * src/io-jpeg.c (image_begin_load): Add update_func callback.
2484 * src/io-jpeg.c (image_load_increment): Call updated callback when
2485 new graphic data decoded.
2487 1999-11-04 Jonathan Blandford <jrb@redhat.com>
2489 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_update): handle the
2491 * src/io-png.c (image_begin_load): add a update_func callback.
2492 * src/io-gif.c (image_begin_load): add a update_func callback.
2493 (gif_get_lzw): added the update_func ability
2495 * src/io-tiff.c (image_begin_load): add a update_func callback.
2497 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2499 * doc/tmpl/gdk-pixbuf.sgml: Populated.
2501 * doc/tmpl/refcounting.sgml: Populated.
2503 * doc/tmpl/file-loading.sgml: Populated.
2505 * src/gdk-pixbuf.c: Added documentation comments.
2507 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Added
2508 documentation comments.
2510 * doc/: Finished integrating the documentation framework.
2512 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2514 * configure.in: Removed libgif stuff now that we do not depend on it.
2515 Added the necessary cruft for gtk-doc.
2517 * src/Makefile.am: Unconditionally build the GIF loader.
2519 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2521 * src/io-gif.c (gif_read): renamed ReadOK to gif_read.
2522 Added a lot of comments to the file.
2524 * src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on
2527 1999-11-03 Michael Fulbright <drmike@redhat.com>
2529 * src/io-jpeg.c (image_load_increment): Further removal of
2530 bugginess in local buffering code. Handles grayscale jpegs
2533 * src/io-jpeg.c (image_load_stop): Was freeing local context
2534 for jpeg library before calling jpeg_decompres_finish ().
2536 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2538 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
2540 (gif_get_lzw): set the transparency to the right val.
2542 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2544 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
2545 Initiailize the x and y fields.
2546 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
2547 (PixbufPrivate): Renamed need_size_update to need_xform_update.
2548 (recompute_bounding_box): Do not use temporary values.
2550 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2552 * src/io-gif.c (set_gif_lzw_clear_code): new state. Fixes
2555 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): remove
2556 unneeded x,y,h,w vars.
2558 1999-11-03 Larry Ewing <lewing@gimp.org>
2560 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
2561 render_affine calculation for x,y offsets.
2562 (gnome_canvas_pixbuf_set_arg): add x,y args.
2563 (gnome_canvas_pixbuf_get_arg): add x,y args.
2564 (recompute_bounding_box): simply code using ArtDrect and the
2565 render_affine. Removed compute_xform_vectors as it was no longer
2568 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2570 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
2571 doofus. Return a distance, not a boolean, for opaque images.
2573 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
2574 rounding of bounding box coordinates.
2575 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
2576 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
2578 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2580 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
2582 1999-11-03 Michael Fulbright <drmike@redhat.com>
2584 * src/io-jpg.c (image_load_increment): Fixed code which moved
2585 buffer around as new data comes in to work properly. JPEG progressive
2586 loading should be working now except for grayscale JPEG's, which I
2587 will look into next.
2589 1999-11-03 <sopwith@redhat.com>
2590 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
2591 Also put dot printing back in.
2593 1999-11-03 <jrb@redhat.com>
2595 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
2598 1999-11-02 Cody Russell <bratsche@dfw.net>
2599 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
2600 if part of the requested image is offscreen, rather than clipping
2603 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2605 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
2606 for interlacing and progressive loading.
2608 1999-11-02 Cody Russell <bratsche@dfw.net>
2609 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
2610 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
2612 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2614 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
2615 It's a little slow though. )-:
2617 1999-11-02 Elliot Lee <sopwith@redhat.com>
2618 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
2619 write/load_increment operations const-correct.
2621 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2623 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
2624 Implemented the ::point() method. We do a simple containment test
2625 instead of a full distance calculation since the canvas is going
2626 to change to that scheme, anyways.
2628 1999-11-02 Elliot Lee <sopwith@redhat.com>
2630 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
2631 that are read from the input file.
2633 1999-11-02 Larry Ewing <lewing@gimp.org>
2635 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
2637 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
2640 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2642 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
2643 affine computation code from ::draw() to here, since it is needed
2644 by ::point() as well.
2646 1999-11-02 Elliot Lee <sopwith@redhat.com>
2648 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
2649 three functions, and eliminate duplication of code from write()
2650 and close(). Also fix bug where the 128-byte header was being
2653 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2654 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
2655 bounding box computation.
2657 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2659 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
2660 Drawing affines seem to work. Bounding box is fubared. ::point()
2661 is not implemented. This is a work in progress.
2663 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
2666 * configure.in: Sigh. We need to link in libgnomeui for the
2667 canvas stuff. This mess will disappear when gdk-pixbuf gets
2668 folded into gnome-libs.
2670 1999-10-30 Jonathan Blandford <jrb@redhat.com>
2672 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
2673 the right size, at a minimum, even if the image is squished and
2675 (ReadImage): lets get the offset right. This will let transparent
2678 1999-10-29 Michael Fulbright <drmike@redhat.com>
2680 * src/io-jpeg.c: image_load_increment(): Fixed bug when
2681 image width was not a multiple of 4 - always use the
2682 gdk_pixbuf rowstride to increment pointers!
2684 1999-10-29 Michael Fulbright <drmike@redhat.com>
2686 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
2687 Currently does not handle either progressive jpeg files (jpeg
2688 files with multiple scans at different quality settings), but
2689 I plan on adding this support soon. These are fairly rare in
2690 my experience, so it shouldn't slow people down too much.
2691 Grayscale jpegs also don't work but that should be easy to fix.
2693 1999-10-29 Michael Fulbright <drmike@redhat.com>
2695 * src/testpixbuf.c: Added title to windows so you can identify
2696 progressive and file windows.
2698 1999-10-29 Michael Fulbright <drmike@redhat.com>
2700 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
2701 load the image handler when we determine the image type.
2703 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
2704 previously static function load_image_handler () to
2705 a public function gdk_pixbuf_load_module (). It is needed in
2706 gdk-pixbuf-loader.c to load image handler modules. This function
2707 is different from gdk_pixbuf_get_module (), which only returns
2708 a reference to the required handler, because it actually loads
2709 the handler into memory. Both actions should possibly be combined
2710 in a convenience function since one w/o the other doesn't seem to

2915 GdkPixBuf to GdkPixbuf, for consistency with the function names
2916 (and it is also easier to type) :-)
2918 1999-10-18 Havoc Pennington <hp@pobox.com>
2920 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
2922 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS

2932 comment out testpixbuf for now
2934 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2936 * configure.in: Use $GTK_LIBS as the extra libs when checking for
2937 libgif/libungif, as they need the X libraries. Fixes bug #2472.
2939 1999-10-10 Cody Russell <bratsche@dfw.net>
2940 * src/gdk-pixbuf-drawable.c: core function now determines whether
2941 the requested geometry is on screen or not, and if some is not
2942 then the request is clamped to geometry that is on the screen.
2944 Changed 'pixbuf' to 'art_pixbuf' in core function.
2946 1999-10-08 Michael Fulbright <drmike@redhat.com>
2948 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

2954 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
2955 them, but I wrote them).
2957 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
2960 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
2961 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

3042 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3043 require extra libraries if we actually have those libraries.
3045 1999-07-23 Richard Hestilow <hestgray@ionet.net>

3057 1999-07-18 Larry Ewing <lewing@gimp.org>
3062 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3063 error cases but one or two in the common case. There are probably
3064 a few small ones left.
3066 1999-07-18 Mark Crichton <crichton@gimp.org>
3068 * configure.in: removed version.h.
3070 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability

3090 loading code so that poeple can diagnose problems better.
3092 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3093 no longer allocates a new pixbuf, which make things nicer for the
3094 rest of the code. Unfortunately there is still a problem with
3095 scaling rgba images.
3097 1999-07-16 Mark Crichton <crichton@gimp.org>
3099 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3100 calls gdk_pixbuf_scale. However, something is not working.
3101 N.B.: current pixmap is now stored in user_data with a key of
