334 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
335 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't

397 - four valid ppm's, eight invalid (matthiasc@poet.de)
398 - one invalid xpm (matthiasc@poet.de)
399 - one valid tga, one invalid (sandmann@daimi.au.dk)
400 - one invalid tiff (sandmann@daimi.au.dk
402 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
404 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
405 fail - detect it when it happens
407 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
410 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
413 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
415 * Makefile.am: don't used BUILT_SOURCES to build marshal
416 files, as in conjunction with stamp files, this can
417 lead to endless rebuilding loops.

421 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1

465 2001-08-07 Sven Neumann <sven@gimp.org>
467 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
468 function, so that's what I did.

549 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
550 already includes top_builddir
552 2001-06-08 Havoc Pennington <hp@redhat.com>
554 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
555 bogus g_return_if_fail
557 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
558 likely timeout resolution, set it to an arbitrarily-chosen short
560 Fixes bug #55953 from warmenhoven@yahoo.com
562 2001-06-07 Havoc Pennington <hp@redhat.com>
564 * Makefile.am: use Owen's new way of doing stampfiles/generated
567 2001-06-07 Havoc Pennington <hp@redhat.com>
569 * Makefile.am (gdk-pixbuf-marshal.c): fix up the glib-genmarshal path
571 2001-06-05 Havoc Pennington <hp@redhat.com>
573 * test-loaders.c (main): use putenv not setenv, reported by
576 2001-05-08 Havoc Pennington <hp@redhat.com>
578 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
579 and fix behavior to still subst color if the original image
582 2001-06-04 Havoc Pennington <hp@redhat.com>
584 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
587 2001-06-01 Havoc Pennington <hp@redhat.com>
589 Apply patch from sandmann@daimi.au.dk, with some tweaks.
590 Makes things a bit more robust, and adds test-loaders.c
591 which is good for finding further robustness bugs to fix.
593 * io-tiff.c: Try to work around libtiff suckiness a bit;
594 put a giant thread lock on the whole loader,
595 paranoically check both whether error handlers were called and
596 also whether functions return false. Handle case where width or
597 height is 0. Various cleanups.
599 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
601 (png_error_callback): apparently libpng expects you to longjmp out
604 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
605 (lzw_read_byte): change "Mail jrb if this fails" g_warning
607 (gif_get_lzw): check for out-of-memory
608 (gif_prepare_lzw): catch/report an error
609 (new_context): use try_malloc, since GifContext is nearly 70K
610 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
611 so we don't crash later.
613 * Makefile.am: Add test-loaders
615 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
618 2001-05-29 Darin Adler <darin@eazel.com>
620 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
622 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
624 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
625 fix up bmp decoder to:
626 - adds 16 bpp bmp support (bug #53884)
627 - adds OS/2 1.x format bmp support (bug #54964)
628 - adds 4 bpp RLE compressed bmp support
629 - adds 1 bpp colormap support
630 - fixes negative height (top down) bmp support
632 2001-05-25 Hans Breuer <hans@breuer.org>
634 * gdk_pixbuf.def : reflect Havoc's recent api change
636 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
638 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
641 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
643 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
645 2001-05-04 Havoc Pennington <hp@redhat.com>
647 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
648 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
651 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
652 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
653 confusion of using "src" instead of "p".
654 (pixops_composite_color_nearest): Use a more accurate (and
655 correct, to begin with) compositing method. This cures checks
656 showing through on images with no alpha.
658 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
661 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
663 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
664 area_updated signal to use signed ints. Removed animation-related
667 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
670 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
671 all the pesky details. Remove old frame-based API. Make
672 GdkPixbufAnimation an abstract base class, derived by the loaders.
674 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
676 * Makefile.am (LDADDS): Add $(MATH_LIB).
678 2001-04-18 Havoc Pennington <hp@redhat.com>
680 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
683 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
685 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
686 so we don't try to get <gtk/gtkobject.h> from standard search
689 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
690 add gdk-pixbuf-marshal.list to EXTRA_DIST.
691 take gdk-pixbuf-marshal.h out of _la sources.
693 2001-03-19 Tor Lillqvist <tml@iki.fi>
695 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
697 * gdk_pixbuf.def: Update.
699 * pixbufloader_*.def: Just export the fill_vtable functions now.
701 2001-03-18 Mike Kestner <mkestner@ameritech.net>
703 * make-inline-pixbuf.c (main): Added logic to remove output when
706 2001-03-14 Havoc Pennington <hp@redhat.com>
708 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
709 from gdk-pixbuf-marshal.h, fixes parallel makes.
711 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
713 * test-gdk-pixbuf.c: fixed includes.
715 2001-02-18 Havoc Pennington <hp@pobox.com>
717 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
718 (gdk_pixbuf_get_named_module): prepend underscore
719 (gdk_pixbuf_get_module): prepend underscore
721 2001-02-19 Havoc Pennington <hp@redhat.com>
723 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
725 2001-02-17 Havoc Pennington <hp@pobox.com>
727 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
729 2001-02-07 Alexander Larsson <alexl@redhat.com>
731 * io-xpm.c (free_buffer):
732 Use g_free, since the buffer is allocated with g_try_alloc().
734 2001-02-06 Christophe Merlet <redfox@eikonex.org>
736 * gdk-pixbuf-data.c: Fixes a minor typo.
738 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
740 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
741 we finally need the gobject->gruntime rename.
743 * *.c: scratched calls to g_type_init(), there's simply no point in
744 doing that, use gtk_init().
746 2001-02-01 Havoc Pennington <hp@pobox.com>
748 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
749 in struct to "priv" for C++
751 2001-01-31 Havoc Pennington <hp@pobox.com>
753 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
755 2001-01-26 Havoc Pennington <hp@redhat.com>
757 * gdk-pixbuf-io.c (mname): fix included modules case.
759 2001-01-22 Havoc Pennington <hp@redhat.com>
761 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
762 from gdk_pixbuf_load_module
764 2001-01-22 Havoc Pennington <hp@redhat.com>
766 * Makefile.am: Add built marshaller files to support
767 GdkPixbufLoader signals
769 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
770 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
771 module location, rather than acting as a fallback, because we are
772 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
774 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
776 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
777 from gtk, and add error to close(), because stop_load may do
778 parsing of the image.
780 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
782 * io-*.c: make individual operations static, and add fill_vtable
783 functions which are exported. Fix the collection of type warnings
784 that surfaced, including a number of functions that didn't
785 properly take a GError and some that weren't
786 const-correct. Involved adding error handling for a few loaders.
788 * gdk-pixbuf-io.h: Add error reporting to stop_load function
790 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
791 a function that fills in the GdkPixbufModule vtable, instead of
792 looking up all the image functions individually; this means we
793 can get type safety within modules for the loader functions.
794 Also it means you don't have to keep the statically compiled and
795 GModule versions in sync.
797 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
799 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
801 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
803 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
806 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
808 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
811 2001-01-20 John Harper <jsh@eazel.com>
813 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
814 collision between Xlib's RdBitF.c and io-tiff.c
816 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
819 [ merged from stable gdk-pixbuf module. Untested, but it
820 compiles, and works fine in the stable module ]
822 2001-01-18 Tor Lillqvist <tml@iki.fi>
824 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
825 g_win32_get_package_installation_subdirectory() function. No need
826 to include windows.h.
827 (gtk_win32_get_installation_directory): Remove this then.
829 2001-01-01 Havoc Pennington <hp@redhat.com>
831 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
832 @LIBTOOL_EXPORT_OPTIONS@
834 2000-12-30 Tor Lillqvist <tml@iki.fi>
836 * gdk_pixbuf.def: Update.
838 2000-12-16 Havoc Pennington <hp@pobox.com>
840 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
841 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
842 (gdk_pixbuf_frame_copy): new function
843 (gdk_pixbuf_frame_free): new function
844 (gdk_pixbuf_frame_get_type): new function
845 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
847 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
849 * Makefile.am: Add -avoid-version for all modules.
851 2000-11-13 Havoc Pennington <hp@redhat.com>
853 * io-png.c (png_simple_error_callback): fix error message to not
854 say "save" since it's used for loading
856 2000-11-11 Hans Breuer <Hans@Breuer.Org>
858 * gdk-pixbuf-io.c : Fix all function prototype macros for self
859 contained image handlers (!USE_G_MODULE). Files to save should
860 be opened in binary mode, fopen(s, "wb").
862 * io-xpm.c : added HAVE_UNISTD_H condition
864 2000-11-11 Tor Lillqvist <tml@iki.fi>
866 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
868 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
869 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
870 mktemp() and open()).
872 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
874 2000-11-01 Havoc Pennington <hp@pobox.com>
876 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
877 a pixbuf pointing to a subregion of another pixbuf.
879 2000-10-16 Tor Lillqvist <tml@iki.fi>
881 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
883 2000-10-16 Havoc Pennington <hp@redhat.com>
885 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
886 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
887 add error reporting here also
889 * make-inline-pixbuf.c (main): use GError
891 * io-xpm.c: include unistd.h
893 * gdk-pixbuf-util.c: include string.h
895 * io-*.c: add error reporting
897 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
900 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
902 * gdk-pixbuf-io.h: Add GError** to load_increment and load
905 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
906 a G_FILE_ERROR if we fail to write or close the file.
908 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
909 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
910 the GError naming rules. Add GError** to load functions.
912 2000-10-06 Havoc Pennington <hp@redhat.com>
914 * gdk-pixbuf.h: add GdkPixbufAlphaMode
916 2000-10-06 Havoc Pennington <hp@redhat.com>

944 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
946 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
947 last nights code was still "broken". Should now properly handle
948 all error conditions gracefully.
950 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
952 * gdk-pixbuf/io-pnm.c: Rewrote.

965 * gdk-pixbuf/io-tiff.c: stop leaking context->tempname.
967 * gdk-pixbuf/io-xpm.c: same as above.
969 2000-07-26 Michael Meeks <michael@helixcode.com>

974 2000-07-21 Larry Ewing <lewing@helixcode.com>
976 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
977 xpm at least supports the progressive interface like the one in
978 io-tiff.c. This should be reimplemented as an actual progressive
981 2000-07-19 Jonathan Blandford <jrb@redhat.com>
983 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
985 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
986 meeks to handle errors better.
988 2000-10-07 Tor Lillqvist <tml@iki.fi>

1002 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
1004 2000-10-05 Havoc Pennington <hp@redhat.com>
1006 Pixbuf saving, patch from David Welton.
1008 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
1009 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h

1030 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
1031 all three of these files are the JPEG image loader. (From
1034 2000-10-03 Tor Lillqvist <tml@iki.fi>
1036 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
1037 gdk-pixbuf's version number in the rule for makefile.mingw itself.
1039 * gdk_pixbuf.def: Add new entry points.
1041 2000-09-26 Havoc Pennington <hp@redhat.com>
1043 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
1044 function here, instead of putting it in a private GTK+ file.
1046 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
1047 enum here for the known formats of inlined pixbufs.
1048 Also, #define our file magic here.
1050 2000-06-23 Havoc Pennington <hp@redhat.com>
1052 * make-inline-pixbuf.c: Small program that creates C variable
1053 declarations of inline pixbuf data. This can be read
1054 by gdk_pixbuf_new_from_inline.
1056 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
1057 inline pixbuf data and create a pixbuf from it.
1059 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
1061 2000-09-07 Tor Lillqvist <tml@iki.fi>
1063 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
1066 2000-08-12 Tor Lillqvist <tml@iki.fi>
1068 * gdk_pixbuf.def: Add missing entry point.
1070 2000-08-10 Havoc Pennington <hp@redhat.com>
1072 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
1073 (s/pixbuf_/pixbufloader_)
1075 2000-08-02 Tor Lillqvist <tml@iki.fi>
1081 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1083 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1084 one. Fix names of DLLs to have '-' instead of '_'.
1086 2000-07-31 Elliot Lee <sopwith@redhat.com>
1087 * io-wbmp.c: Some bug fixes - now tested to work.
1089 2000-07-27 Elliot Lee <sopwith@redhat.com>
1091 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1092 gdk_pixbuf_get_named_module() function to facilitate above change
1093 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1094 Implement loader for WBMP format.
1095 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1097 2000-07-23 Tor Lillqvist <tml@iki.fi>
1102 * pixops/makefile.mingw.in
1103 * pixbuf_*.def: New files.
1106 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1108 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1109 New function, to get the GTK+ installation directory from
1110 the Windows Registry, where the installation program
1111 for whatever software includes GTK+ has stored it.
1113 Used to avoid having hardcoding the directory where to look for
1114 loaders. This function is needed by gtk, too, so it should
1115 really be just in one place. Maybe a small static library
1116 one level up from here?
1118 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1119 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1120 Open file in binary mode. This *is* standard C. (No-op on Unix,
1123 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1125 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1126 mktemp() and open().
1127 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1129 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1130 pseudo-op. Conditionalise on __MINGW32__, but probably
1131 should conditionalise on Gas version instead? Or could we
1132 do without .type on all systems?
1134 * pixops/timescale.c: Use g_get_current_time()
1135 instead of gettimeofday().
1137 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1139 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1141 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1143 * gdk-pixbuf.c: Add <string.h> include.
1145 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1147 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1148 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1149 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1150 use g_object_new() instead of g_type_create_instance() which
1151 is a private function for fundamental type implementations.
1153 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1155 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1156 soname scheme for gdk-pixbuf.
1158 2000-06-21 Havoc Pennington <hp@pobox.com>
1160 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1161 (i.e. derivation is not allowed, and there are no virtual methods
1163 (gdk_pixbuf_preinit): Call g_type_init() here.
1164 (gdk_pixbuf_init): Add a user-friendly init function, for users
1165 of standalone gdk-pixbuf
1167 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1168 way GdkPixbufAnimation was done.
1170 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1171 gdk_pixbuf_finalize() from API, since these are broken and don't
1172 make sense with new GObject stuff.
1174 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1176 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1177 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1180 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1182 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1183 so I needed something to warm my thighs. Running plain infinite
1184 loops on your laptop to make it hot is not very much fun. A demo
1185 of the gdk-pixbuf scaling functions is way better, and looks
1188 * configure.in (AC_OUTPUT): Added the demo Makefile.
1190 * Makefile.am (SUBDIRS): Added the demo directory.
1192 2000-06-09 Larry Ewing <lewing@helixcode.com>
1194 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1195 setjmp for the png error handler. It seems setting the error
1196 handling functions does not avoid the jump, and so not calling
1197 setjmp was causing the incremental loader to jump into lala land.
1198 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1199 not sure this one is actually required but the docs say it must be
1200 set for every call to a png_* function.
1201 Also changed the comment to reflect the fact that setting the
1202 error handlers does _not_ avoid the longjmp.
1204 2000-06-06 Larry Ewing <lewing@helixcode.com>
1206 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1207 take frame offest into account when trying to calculate the
1208 animation bbox. Also set the width to the width not the height.
1209 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1210 calculate bbox because now we finally have all the offset
1211 information for each frame.
1213 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
1215 * configure.in: add some gtk parameters to the
1216 GDK_PIXBUF_LIB²S and GDK_PIXBUG_INCLUDEDIR vars. One more
1217 fight in my crusade for strange prefix compile...
1219 2000-05-30 Not Zed <NotZed@HelixCode.com>
1221 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
1222 Initialise the error handler exit routine to our own. Note this
1223 means that every function that accesses the jpeg lib on this
1224 object MUST do a setjmp.
1225 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
1226 lib for handling fatal error.
1227 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
1228 your applications dont quit if there's a jpeg error!
1230 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
1232 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
1233 from Frank de Lange <frank@unternet.org>.
1235 2000-05-09 Darin Adler <darin@eazel.com>
1237 * gdk-pixbuf/test-gdk-pixbuf.c:
1238 Fixed includes to get rid of accidental GNOME dependency.
1240 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
1241 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
1243 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
1245 * configure.in: Bumped version number to 0.8.0.
1247 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
1248 file was not being distributed.
1250 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
1252 2000-05-09 Darin Adler <darin@eazel.com>
1254 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
1255 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
1256 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
1257 formats to 32-bit formats to re-use the high bits of the color values
1258 so that white maps to full white.
1260 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
1262 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
1263 detailed information about the structure and algorithms
1264 of pixops so people can fix it instead of breaking it.
1266 2000-05-04 Darin Adler <darin@eazel.com>
1268 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
1269 (composite_pixel), (composite_line):
1270 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
1271 Now that Owen explained the algorithm, I think I implemented it
1272 right for the cases where the destination pixbuf is not opaque.
1273 The test does seem to confirm it.
1275 2000-05-04 Darin Adler <darin@eazel.com>
1277 * gdk-pixbuf/.cvsignore:
1278 * gdk-pixbuf/Makefile.am:
1279 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
1280 (load_pixel), (simple_composite_test_one),
1281 (simple_composite_test_one_type), (simple_composite_test), (main):
1282 Added some tests of composite to highlight problems in the old
1283 implementation. These tests run without any user interaction.
1284 Just do "make check".
1286 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
1287 (composite_pixel), (composite_line): Fix composite to do a textbook
1288 "A over B" composite. This was clearly the intent, and it was easy
1289 to fix the code to do it. (Note to those that read my earlier tries
1290 at a patch; this version fixes typos that were present in all
1291 my patch attempts. I checked the final version by adding more tests.)
1293 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
1295 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
1296 offset y coordinate accordining to render_y0.
1298 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
1301 2000-04-22 James Henstridge <james@daa.com.au>
1303 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
1304 package to the devel package. The only file installed in bin is
1305 gdk-pixbuf-config, which belongs in -devel. This should allow having
1306 multiple versions of the main gdk-pixbuf package installed.
1308 2000-04-17 Karl Eichwalder <ke@suse.de>
1310 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
1311 Reported by Jens Finke.
1313 2000-04-14 Tomasz K³opczko <kloczek@pld.org.pl>
1315 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
1316 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
1318 2000-04-13 James Henstridge <james@daa.com.au>
1320 * configure.in: when performing the configure check to see if
1321 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
1322 rather than the other way round. Also, call AC_MSG_RESULT in the
1323 even that dynamic modules were not supported.
1325 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
1327 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
1328 hook to the last unref operation.
1330 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
1331 function to set the last unref handler for a pixbuf.
1332 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
1333 It calls the pixbuf's destroy notification function and frees the
1334 GdkPixbuf structure itself.
1335 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
1338 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
1339 for the last unref handler and its user data.
1341 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
1342 g_new0() to allocate the pixbuf.
1344 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
1345 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
1346 was not specifying the `frame' argument.
1348 * gdk-pixbuf/gdk-pixbuf-animation.c
1349 (gdk_pixbuf_animation_get_width): Fixed docstring.
1350 (gdk_pixbuf_animation_get_height): Likewise.
1351 (gdk_pixbuf_animation_get_num_frames): Likewise.
1352 (gdk_pixbuf_animation_get_frames): Likewise.
1354 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
1357 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
1359 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
1361 * doc/tmpl/refcounting.sgml: Updated with the information about
1362 the last unref handler.
1364 * doc/tmpl/*.sgml: Markup tweaks.
1366 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
1367 update the libtool version number for libgnomecanvaspixbuf as
1369 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
1370 as well, or the old ones won't work with the new stuff. Also,
1371 renamed the modules as follows.
1373 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
1374 modules are called "libpixbufloader-<format>.so" instead of
1375 "libpixbuf-<format>.so". They needed renaming so that the new
1376 loaders won't overwrite the old ones; even with the versioning
1377 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
1380 2000-04-12 Paolo Molaro <lupus@debian.org>
1382 * .cvsignore, src/.cvsignore: shut up cvs.
1384 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
1386 Most of this patch is based on a patch by Havoc Pennington
1387 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
1388 remove the libart dependency.
1390 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
1391 (GdkColorspace): New enum that for now only contains
1393 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
1394 notification function.
1395 (GdkInterpType): New num with interpolation types.
1397 * *.[ch]: Replace the libart stuff with our own stuff.
1399 * pixops/*.[ch]: Likewise.
1401 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
1402 declarations of the GdkPixbuf structures.
1404 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
1406 (gdk_pixbuf_get_format): Constify.
1407 (gdk_pixbuf_get_n_channels): Constify.
1408 (gdk_pixbuf_get_has_alpha): Constify.
1409 (gdk_pixbuf_get_bits_per_sample): Constify.
1410 (gdk_pixbuf_get_pixels): Constify.
1411 (gdk_pixbuf_get_width): Constify.
1412 (gdk_pixbuf_get_height): Constify.
1413 (gdk_pixbuf_get_rowstride): Constify.
1415 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
1418 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
1419 bits_per_sample argument; currently only 8 bits per sample are
1422 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
1424 (gdk_pixbuf_frame_get_x_offset): New accessor.
1425 (gdk_pixbuf_frame_get_y_offset): New accessor.
1426 (gdk_pixbuf_frame_get_delay_time): New accessor.
1427 (gdk_pixbuf_frame_get_action): New accessor.
1429 * gdk-pixbuf/gdk-pixbuf-render.c
1430 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
1431 mask rectangle for pixbufs without an alpha channel, set the
1432 *mask_return to NULL.
1434 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
1436 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
1438 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
1439 preconditions. Maybe we should also check for the colorspace,
1440 bits per pixel, and such.
1441 (gdk_pixbuf_composite): Likewise.
1442 (gdk_pixbuf_composite_color): Likewise.
1443 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
1444 cannot allocate the new pixbuf.
1445 (gdk_pixbuf_composite_color_simple): Likewise.
1447 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
1448 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
1451 * gdk-pixbuf/io-bmp.c: Fix includes.
1453 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
1458 * configure.in: Removed checks for libart.
1460 * gdk-pixbuf/Makefile.am: Removed references to libart.
1461 (noinst_HEADERS): Added gdk-pixbuf-private.h.
1463 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
1464 the version number of the libtool library to indicate that this
1465 definitely is not compatible with the old usage. I know you love
1468 * configure.in: Bumped version number to 0.7.0.
1472 * gdk-pixbuf-config.in (--libs): We no longer require libart.
1474 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
1476 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
1478 2000-04-06 Jonathan Blandford <jrb@redhat.com>
1480 * gdk-pixbuf/testanimation.c (main): add more info to the
1481 testanimation frames.
1483 2000-04-04 Ettore Perazzoli <ettore@helixcode.com>
1485 * gdk-pixbuf/gdk-pixbuf-animation.c
1486 (gdk_pixbuf_animation_get_width): New accessor function.
1487 (gdk_pixbuf_animation_get_height): New accessor function.
1488 (gdk_pixbuf_animation_get_num_frames): New accessor function.
1489 (gdk_pixbuf_animation_get_frames): New accessor function.
1491 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
1493 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
1494 is private information, and the art_pixbuf will go away soon.
1496 2000-03-31 Mark Crichton <crichton@gimp.org>
1498 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
1499 and gdk_pixbuf_get_artpixbuf accessor functions.
1501 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
1503 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
1504 gboolean instead of int.
1506 2000-03-29 Radek Doulik <rodo@helixcode.com>
1508 * gdk-pixbuf/gdk-pixbuf-animation.c
1509 (gdk_pixbuf_animation_new_from_file): same as below
1511 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
1512 height in GdkPixbufAnimation
1514 2000-03-28 Radek Doulik <rodo@helixcode.com>
1516 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
1517 context->frame_done_func and context->anim_done_func to make
1518 progressive animation loading work
1520 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1521 added priv->pixbuf = NULL as pixbuf is now in frame (and to make
1522 gdk_pixbuf_loader_prepare happy)
1523 (gdk_pixbuf_loader_frame_done): update animation bbox
1525 * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to
1528 2000-03-27 Radek Doulik <rodo@helixcode.com>
1530 * gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width
1531 instead of width and height
1533 2000-03-27 Owen Taylor <otaylor@redhat.com>
1535 * gdk-pixbuf/pixops/pixops.c: Fix problem with
1536 precendence of >> and & which was keeping composite_color
1537 from working with non-gray images.
1539 2000-03-08 Jonathan Blandford <jrb@redhat.com>
1541 * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context.
1542 (gdk_pixbuf__gif_image_load_animation): free the context.
1544 2000-03-06 Arjan van de Ven <arjan@fenrus.demon.nl>
1546 * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a
1547 mis-interpretation of the Microsoft documentation. Now
1548 it can load .BMP files that are not generated by The Gimp
1551 2000-03-01 Mark Crichton <crichton@gimp.org>
1553 * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
1554 fix the last auto* build bug (where we have libart, but no
1557 * gdk-pixbuf/Makefile.am: Same.
1559 2000-02-28 Matt Wilson <msw@redhat.com>
1561 * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,
1562 s/unsigned short/guint16/g, s/unsigned char/guint8/g
1564 2000-02-26 Federico Mena Quintero <federico@helixcode.com>
1566 * README: We don't require libgif/ungif nor libXpm.
1568 * NEWS: This was outdated, so updated it.
1570 2000-02-25 Federico Mena Quintero <federico@helixcode.com>
1572 * gdk-pixbuf.m4: Use the correct name for
1573 gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing
1576 2000-02-21 Federico Mena Quintero <federico@helixcode.com>
1578 * configure.in (GDK_PIXBUF_MINOR): Bumped version number to 0.6.0.
1580 * doc/compiling.sgml: New appendix documenting the gdk-pixbuf
1581 library's particular options to configure.in.
1583 * doc/gdk-pixbuf.sgml: Include compiling.sgml appendix via an
1586 * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml.
1588 * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment):
1589 Fixed typo in prototype name.
1591 * configure.in: Changed duplicated AC_MSG_CHECKING message to
1592 something more meaningful; now it is "checking whether dynamic
1595 * gdk-pixbuf/pixops/Makefile.am (noinst_PROGRAMS): Do not install
1596 the timescale program.
1598 Integrated Miguel de Icaza's <miguel@gnu.org> patch for optionally
1599 creating a single static library with all the image format modules
1602 2000-02-20 Miguel de Icaza <miguel@gnu.org>

1969 animation functions here.
1970 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
1971 animation if the loader does not support multiframe loading and

2012 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
2013 set to NULL here (specifically context->animation) was not being

2016 1999-12-20 Jonathan Blandford <jrb@redhat.com>
2018 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
2019 correctly. Progressive loading needs some work, but that all
2020 needs doing from the gdk-pixbuf-loader end, not here.
2022 1999-12-17 Jonathan Blandford <jrb@redhat.com>
2024 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2025 moved the file here. It seems natural to put this function here,
2026 as that's where the gdk_pixbuf_new_from_file function is, but it's
2027 still a little convoluted. The source files might be played with
2030 1999-12-14 Jonathan Blandford <jrb@redhat.com>

2044 * gdk-pixbuf/gnome-canvas-pixbuf.c
2045 (gnome_canvas_pixbuf_class_init): Renamed arguments to

2077 (rgbconvert): Added GdkColormap parameter, and to all conversion
2079 (convert_real_slow): New function - should convert ANY visual/data
2080 format properly, but it aint fast. Used as a fallback when an
2081 optimised routine wont match.
2082 (rgbconvert): Do very specific tests on the data format to verify
2083 properly if the optimised version will do, otherwise use the
2084 fallback function for all other data formats.
2086 * gdk-pixbuf/Makefile.am: Re-enabled building of
2087 textpixbuf-drawable.
2089 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use

2102 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2103 checks and API definition. The body needs filling in and it needs
2104 to do the Right Thing(tm) for pixmaps plus the given colormap and
2105 windows and their own colormaps.
2107 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2108 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.

2145 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2146 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2147 want, send me a patch to do the conditional stuff properly.

2172 except for the signature and 2 extra fields for the hotspot.
2174 1999-12-03 Federico Mena Quintero <federico@redhat.com>
2176 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):

2182 explain this function better.
2184 1999-12-02 Federico Mena Quintero <federico@redhat.com>
2186 Source files moved from src/ to gdk-pixbuf/, to be consistent with

2259 * doc/tmpl/util.sgml: Documentation for the utility functions.
2261 1999-11-29 Owen Taylor <otaylor@redhat.com>
2263 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
2264 Keep the mask around until after we draw ... since
2265 the GC changes aren't flushed to the X server until we
2266 draw, destroying it before that may result in BadPixmap
2269 1999-11-30 Havoc Pennington <hp@pobox.com>
2271 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
2273 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
2275 1999-11-29 Federico Mena Quintero <federico@redhat.com>
2277 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
2278 should be made conditional, not blindly commented out.
2280 1999-11-29 Jonathan Blandford <jrb@redhat.com>
2282 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
2283 handle .ico files. Cool.
2285 1999-11-24 Jonathan Blandford <jrb@redhat.com>
2287 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
2290 1999-11-24 James Henstridge <james@daa.com.au>
2292 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
2293 top builddir rather than src. This still builds fine, and does not
2294 get gtk-doc into an infinite loop when trying to find all the source
2297 1999-11-23 Jonathan Blandford <jrb@redhat.com>
2299 * Removed #PRAGMA } from headers. Also, make compile if you don't
2300 have it installed, already.
2302 1999-11-22 Federico Mena Quintero <federico@redhat.com>
2304 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
2305 temporary buffer to the size of the interesction of the bounding
2306 box and the expose area, not the whole expose area. This speeds
2309 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
2310 not paint black on the mask, since we already cleared it in a
2311 single gdk_draw_rectangle() operation.
2313 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
2315 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
2317 1999-11-22 Havoc Pennington <hp@pobox.com>
2319 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
2320 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
2321 dependencies to LIBADD variables for loadable modules. Necessary
2322 for a Java dynamic loading thing to be able to figure it out.
2324 1999-11-22 Havoc Pennington <hp@pobox.com>
2326 * src/io-png.c (image_load_increment): Call the update_area
2327 callback depending on the number of rows loaded in this increment.
2329 * src/testpixbuf.c (main): slow down the progressive load demo
2331 1999-11-16 Havoc Pennington <hp@pobox.com>
2333 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
2335 1999-11-22 Jonathan Blandford <jrb@redhat.com>
2337 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
2338 for srcdir != buildir != . Beats me why; I can't figure it out.
2339 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
2341 1999-11-21 Jonathan Blandford <jrb@redhat.com>
2343 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
2344 <arjan@fenrus.demon.nl>
2346 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2348 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
2349 Rework/reorder of the code. Each case has been separated into
2350 another function; its big but it should be quick.
2351 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
2352 opaque alpha information. Not all depths/formats have been
2353 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
2355 1999-11-17 Larry Ewing <lewing@gimp.org>
2357 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
2358 implement the bounds method correctly.
2359 (compute_viewport_affine): compute the affine need to fit the
2360 image within the viewport given by the args.
2361 (compute_render_affine): call compute_viewport_affine.
2363 1999-11-16 Havoc Pennington <hp@pobox.com>
2365 * src/gdk-pixbuf-drawable.h: Use includes from the current
2366 directory, not the system directory.
2368 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
2370 * src/testpixbuf-drawable.c: use includes from the current directory
2371 rather then from the system include directory as gdk-pixbuf
2372 includes are not yet installed when this is compiled.
2374 1999-11-13 Cody Russell <bratsche@dfw.net>
2375 * src/testpixbuf-drawable.c: Added a test program for drawable
2378 * src/Makefile.am: Build testpixbuf-drawable.
2380 1999-11-12 Cody Russell <bratsche@dfw.net>
2382 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.

2395 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
2398 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
2399 correctly. Patch from Arjan to do so.
2401 1999-11-10 Michael Fulbright <drmike@redhat.com>
2403 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
2406 * src/testpixbuf.c: Added final queued draw when done loading image.
2408 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2410 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
2413 1999-11-10 Federico Mena Quintero <federico@redhat.com>
2415 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
2418 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2420 * src/io-png.c: Fixed some incompatible pointer initializations.
2422 * src/io-jpeg.c (image_load_increment): Remove unused variable.
2424 1999-11-09 Michael Fulbright <drmike@redhat.com>
2426 * src/testpixbuf.c: Fixed it to use timeout to read from file
2427 for progressive loading. Set TBF_KBPS=n, where n is the number of
2428 kilobytes/second to simulate in downloading. n has to be an integer.
2430 * src/io-jpeg.c: Slight cosmetic cleanup.
2432 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
2433 PBM loading has a similar problem and will address tomorrow.
2435 1999-11-09 Havoc Pennington <hp@pobox.com>
2437 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
2438 gdk-pixbuf-drawable stuff.
2440 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2442 * configure.in: Bumped version number to 0.4.
2444 1999-11-09 Michael Fulbright <drmike@redhat.com>
2446 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
2447 all types of PNM files now.
2449 * src/io-jpeg.c (image_load_increment): Figured out problem with
2450 loading Progressive JPEG's progressively (say that 10 times fast).
2451 Currently for Progressive JPEG's the entire image is loaded before
2452 it is displayed. libjpeg supports a fancier mechanism which I may
2455 With these changes all JPEG formats appear to load properly for me.
2457 1999-11-08 Jonathan Blandford <jrb@redhat.com>
2459 * src/io-ras.c (image_load_increment): Final patch from Arjan.
2460 Seems to do progressive loading.
2462 1999-11-08 Michael Fulbright <drmike@redhat.com>
2464 * src/io-pnm.c image_load (): Fixed so we do not create a separate
2465 pixel buffer when reading in image - we reuse the pixel data in
2466 the GdkPixbuf structure instead.
2468 1999-11-08 Michael Fulbright <drmike@redhat.com>
2470 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
2471 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
2472 I can't seem to find a utility to convert into this format.
2473 Next is to add progressive loading support for the PNM format.
2475 1999-11-07 Federico Mena Quintero <federico@redhat.com>
2477 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
2478 of the width, height, x, and y setting and pixels arguments.
2480 1999-11-05 Jonathan Blandford <jrb@redhat.com>
2482 * src/io-ras.c (image_load): third patch. Now it seems to load.

2485 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
2487 * src/io-ras.c (image_load): new file from Arjan van de Ven
2488 <arjan@fenrus.demon.nl> to begin the ras loader.
2490 1999-11-05 Federico Mena Quintero <federico@redhat.com>
2492 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
2493 for internal use only.
2495 * doc/gdk-pixbuf.sgml: Likewise.
2497 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
2499 1999-11-05 Michael Fulbright <drmike@redhat.com>

2503 then incremental loading.
2505 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2507 * Makefile.am: Added doc to SUBDIRS.
2509 1999-11-04 Michael Fulbright <drmike@redhat.com>
2511 * src/io-jpeg.c: Prettied up code slightly.
2512 * src/io-pnm.c: Start of pnm loader (from file and progressively).
2513 Doesn't do much yet (will finish tomorrow).
2514 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
2516 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2518 * doc/tmpl/rendering.sgml: Populated.
2520 * doc/Makefile.am: Added the template files.
2522 1999-11-04 Havoc Pennington <hp@pobox.com>
2524 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
2525 docs, explain what a dither offset is for.
2526 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
2527 this function vs. gdk_pixbuf_render_to_drawable().
2529 1999-11-04 Havoc Pennington <hp@pobox.com>
2531 * configure.in: Use libart-config correctly; find gnome-config
2532 separately. Fix GNOME_LIBS to be correct in "no gnome installed
2535 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
2538 Patch untested in the inside-gnome-libs case, I need to commit
2539 then check out to the gnome-libs I'm using.
2541 1999-11-04 Michael Fulbright <drmike@redhat.com>
2543 * src/io-jpeg.c (image_begin_load): Add update_func callback.
2544 * src/io-jpeg.c (image_load_increment): Call updated callback when
2545 new graphic data decoded.
2547 1999-11-04 Jonathan Blandford <jrb@redhat.com>

2589 * src/io-jpeg.c (image_load_increment): Further removal of
2590 bugginess in local buffering code. Handles grayscale jpegs
2593 * src/io-jpeg.c (image_load_stop): Was freeing local context
2594 for jpeg library before calling jpeg_decompres_finish ().
2596 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2598 * src/io-gif.c (image_load_increment): now handle arbitrary buffer

2621 render_affine calculation for x,y offsets.
2622 (gnome_canvas_pixbuf_set_arg): add x,y args.
2623 (gnome_canvas_pixbuf_get_arg): add x,y args.
2624 (recompute_bounding_box): simply code using ArtDrect and the
2625 render_affine. Removed compute_xform_vectors as it was no longer
2628 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2630 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
2631 doofus. Return a distance, not a boolean, for opaque images.
2633 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
2634 rounding of bounding box coordinates.
2635 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
2636 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
2638 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2640 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
2642 1999-11-03 Michael Fulbright <drmike@redhat.com>
2644 * src/io-jpg.c (image_load_increment): Fixed code which moved
2645 buffer around as new data comes in to work properly. JPEG progressive
2646 loading should be working now except for grayscale JPEG's, which I
2647 will look into next.
2649 1999-11-03 <sopwith@redhat.com>
2650 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
2651 Also put dot printing back in.
2653 1999-11-03 <jrb@redhat.com>
2655 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
2658 1999-11-02 Cody Russell <bratsche@dfw.net>
2659 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
2660 if part of the requested image is offscreen, rather than clipping
2663 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2665 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
2666 for interlacing and progressive loading.
2668 1999-11-02 Cody Russell <bratsche@dfw.net>
2669 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
2670 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
2672 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2674 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
2675 It's a little slow though. )-:

2683 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
2684 Implemented the ::point() method. We do a simple containment test
2685 instead of a full distance calculation since the canvas is going
2686 to change to that scheme, anyways.
2688 1999-11-02 Elliot Lee <sopwith@redhat.com>
2690 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
2691 that are read from the input file.
2693 1999-11-02 Larry Ewing <lewing@gimp.org>
2695 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
2697 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
2700 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2702 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
2703 affine computation code from ::draw() to here, since it is needed
2704 by ::point() as well.
2706 1999-11-02 Elliot Lee <sopwith@redhat.com>
2708 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
2709 three functions, and eliminate duplication of code from write()
2710 and close(). Also fix bug where the 128-byte header was being
2713 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2714 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
2715 bounding box computation.
2717 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2719 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
2720 Drawing affines seem to work. Bounding box is fubared. ::point()
2721 is not implemented. This is a work in progress.
2723 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
2726 * configure.in: Sigh. We need to link in libgnomeui for the
2727 canvas stuff. This mess will disappear when gdk-pixbuf gets
2728 folded into gnome-libs.
2730 1999-10-30 Jonathan Blandford <jrb@redhat.com>
2732 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
2733 the right size, at a minimum, even if the image is squished and
2735 (ReadImage): lets get the offset right. This will let transparent
2738 1999-10-29 Michael Fulbright <drmike@redhat.com>
2740 * src/io-jpeg.c: image_load_increment(): Fixed bug when
2741 image width was not a multiple of 4 - always use the
2742 gdk_pixbuf rowstride to increment pointers!
2744 1999-10-29 Michael Fulbright <drmike@redhat.com>
2746 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
2747 Currently does not handle either progressive jpeg files (jpeg
2748 files with multiple scans at different quality settings), but
2749 I plan on adding this support soon. These are fairly rare in
2750 my experience, so it shouldn't slow people down too much.
2751 Grayscale jpegs also don't work but that should be easy to fix.
2753 1999-10-29 Michael Fulbright <drmike@redhat.com>
2755 * src/testpixbuf.c: Added title to windows so you can identify
2756 progressive and file windows.
2758 1999-10-29 Michael Fulbright <drmike@redhat.com>
2760 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
2761 load the image handler when we determine the image type.
2763 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
2764 previously static function load_image_handler () to
2765 a public function gdk_pixbuf_load_module (). It is needed in
2766 gdk-pixbuf-loader.c to load image handler modules. This function
2767 is different from gdk_pixbuf_get_module (), which only returns
2768 a reference to the required handler, because it actually loads
2769 the handler into memory. Both actions should possibly be combined
2770 in a convenience function since one w/o the other doesn't seem to
2773 1999-10-28 Jonathan Blandford <jrb@redhat.com>
2775 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a

2780 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
2781 function to render a portion of a pixbuf to a drawable. Ignores
2782 alpha information and takes in a GC.
2783 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
2784 portion of a pixbuf to a drawable. It automatically creates a GC
2785 and a clipping mask for alpha pixbufs.
2787 1999-10-28 Jonathan Blandford <jrb@redhat.com>
2789 * src/gdk-pixbuf.h: turned convenience macros into convenience
2790 functions so some error checking could be added.
2792 * src/io-tiff.c (image_load_increment): started work on the tiff
2793 non-incremental loader.
2794 (image_begin_load): Finished the incremental loader.

2801 1999-10-27 Federico Mena Quintero <federico@redhat.com>
2803 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
2804 function to threshold a pixbuf's alpha channel into a bitmap.
2806 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
2807 contemplate future extensions to ArtPixBuf's formats.
2809 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
2811 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
2812 macros to fetch the ArtPixBuf's fields.
2814 1999-10-27 Havoc Pennington <hp@pobox.com>

2819 code into separate function
2820 (png_info_callback): Use setup_png_transformations
2822 1999-10-27 Havoc Pennington <hp@pobox.com>
2824 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
2825 properly whether the XPM module has already been loaded
2826 (gdk_pixbuf_new_from_file): Check properly if loader module
2827 was already loaded (was checking if load symbol was present
2828 in order to decide whether to re-load; should check module !=
2829 NULL, then load != NULL)
2830 (image_handler_load): Check in present working directory,
2831 makes it easier to debug for now
2832 (file_formats): This array initializer was seriously on crack,
2833 was assigning a function pointer to a GModule*
2835 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
2837 1999-10-27 Havoc Pennington <hp@pobox.com>

2841 (gdk_pixbuf_loader_destroy): ditto
2843 1999-10-27 Federico Mena Quintero <federico@redhat.com>
2845 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
2846 GdkPixbufLoader, not a GtkObject.
2847 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
2848 (gdk_pixbuf_loader_get_type): Documented.
2849 (gdk_pixbuf_loader_class_init): Initialize the parent class
2851 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
2852 class destroy function.
2853 (gdk_pixbuf_loader_new): Documented.
2854 (gdk_pixbuf_loader_finalize): Call the parent class finalize
2856 (gdk_pixbuf_loader_write): Use size_t for count.
2858 1999-10-27 Michael Fulbright <drmike@redhat.com>
2860 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
2861 logic so we only try to close loader if it wasn't previously closed.
2863 1999-10-27 Michael Fulbright <drmike@redhat.com>
2865 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of

2892 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
2894 1999-10-22 Havoc Pennington <hp@pobox.com>
2896 * src/io-xpm.c (mem_buffer): Clean up stupid
2897 increment-inside-array-dereference thing
2899 * src/testpixbuf.c: Add XPM data tests.
2901 * src/io-xpm.c: Make the XPM data buffer const, fix const
2902 correctness throughout the code.
2904 1999-10-22 Havoc Pennington <hp@pobox.com>
2906 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()
2908 1999-10-22 Havoc Pennington <hp@pobox.com>
2910 * src/io-xpm.c (image_load_xpm_data): Export this symbol for
2911 loading an XPM from memory.

2914 function, loads pixbuf from xpm data
2915 (image_handler_load): Add g_return_if_fail() to ensure the same
2916 module isn't loaded twice. Add g_module_symbol() to scan for XPM
2919 1999-10-22 Federico Mena Quintero <federico@redhat.com>
2921 * src/io-png.c (image_load): Patch from Kristian Hogsberg
2922 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
2923 buffers; the rows can be read in directly into the main pixel
2926 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2928 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
2930 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2932 * configure.in: Bumped version number to 0.3.
2934 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
2935 version number for the library.
2937 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2939 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
2940 all memory management of the buffer is done by libart.
2942 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
2943 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
2945 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
2946 terms of the libart functions. Removed the old code.
2948 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
2949 symbols. Saving will not be implemented in GdkPixbuf.
2951 * src/io-gif.c: Removed the saving stub.
2952 (image_load): Fixed memory management to fail gracefully if we run
2953 out of memory while loading the image. Close the gif file when we
2954 are done. This still needs more error handling for the DGif
2957 * src/io-jpeg.c (image_load): Some robustness fixes.
2959 * src/io-png.c: Removed the saving stuff.
2960 (image_load): Some memory management fixes.

2970 * autogen.sh: use subautogen.sh
2972 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2974 * src/*: Reindented to use the GNOME Indentation. Renamed
2975 GdkPixBuf to GdkPixbuf, for consistency with the function names
2976 (and it is also easier to type) :-)
2978 1999-10-18 Havoc Pennington <hp@pobox.com>
2980 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
2982 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
2984 1999-10-18 Havoc Pennington <hp@pobox.com>
2986 * Makefile.am (SUBDIRS): Remove "macros"
2988 * configure.in: Don't use GNOME_INIT, handle case where we are
2989 inside gnome-libs. AM_PATH_GTK for the GIF test
2991 * src/Makefile.am: Change flags to work without libgnomeui,
2992 comment out testpixbuf for now
2994 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2996 * configure.in: Use $GTK_LIBS as the extra libs when checking for
2997 libgif/libungif, as they need the X libraries. Fixes bug #2472.
2999 1999-10-10 Cody Russell <bratsche@dfw.net>
3000 * src/gdk-pixbuf-drawable.c: core function now determines whether
3001 the requested geometry is on screen or not, and if some is not
3002 then the request is clamped to geometry that is on the screen.
3004 Changed 'pixbuf' to 'art_pixbuf' in core function.
3006 1999-10-08 Michael Fulbright <drmike@redhat.com>
3008 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

3011 if no filename given to test program.
3013 1999-10-07 Cody Russell <bratsche@dfw.net>
3014 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
3015 them, but I wrote them).
3017 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
3020 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
3021 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

3041 * src/io-tiff.c (image_load): ditto + fix leak
3043 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
3044 crashes this module ( add warning :-)
3046 * src/io-bmp.c (image_load): ditto.
3048 * src/io-gif.c (image_load): ditto.
3050 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
3052 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
3053 it doesn't crash scaling with alpha.
3055 1999-09-17 Federico Mena Quintero <federico@redhat.com>
3057 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
3059 * src/io-gif.c (image_load): Likewise.
3061 * src/io-jpeg.c (image_load): Likewise.
3063 * src/io-png.c (image_load): Likewise.

3078 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
3079 to unallocated memory (row_ptr), and fixed its type as well. Take
3080 into account the ArtPixbuf's rowstride when assigning the row
3083 * src/gdk-pixbuf.c: Fixup includes.
3085 * src/gdk-pixbuf-io.c: Likewise.
3087 Sat Jul 31 19:19:47 CEST 1999

3092 1999-07-29 Mark Crichton <crichton@gimp.org>
3094 * src/io-png.c (image_save): Added PNG saving function
3096 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
3097 image_save(GdkPixBuf *p, FILE *f, ...)
3100 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
3102 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3103 require extra libraries if we actually have those libraries.
3105 1999-07-23 Richard Hestilow <hestgray@ionet.net>
3107 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
3108 * gdk_pixbufConf.sh.in: Added for gnome-config
3110 * configure.in: Modified to generate gdk_pixbufConf.sh
3112 1999-07-20 Mark Crichton <crichton@gimp.org>
3114 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3115 calculation needs to be done.
3117 1999-07-18 Larry Ewing <lewing@gimp.org>
3122 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3123 error cases but one or two in the common case. There are probably
3124 a few small ones left.
3126 1999-07-18 Mark Crichton <crichton@gimp.org>
3128 * configure.in: removed version.h.
3130 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
3133 1999-07-17 Mark Crichton <crichton@gimp.org>
3135 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
3136 (gdk_pixbuf_rotate): Added pixbuf rotation code.
3137 (gdk_pixbuf_scale): Changed // comments to /* */
3139 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
3142 1999-07-16 Larry Ewing <lewing@gimp.org>
3144 * src/testpixbuf.c (expose_func): reverted the expose everything
3145 changes, I'm not sure why these went in.
3146 (config_func): bring this up to date with the new pixbuf_scale
3149 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3150 loading code so that poeple can diagnose problems better.
3152 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3153 no longer allocates a new pixbuf, which make things nicer for the
3154 rest of the code. Unfortunately there is still a problem with
3155 scaling rgba images.
3157 1999-07-16 Mark Crichton <crichton@gimp.org>
3159 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3160 calls gdk_pixbuf_scale. However, something is not working.
3161 N.B.: current pixmap is now stored in user_data with a key of
3164 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
3165 Something is still borked, however.
