309 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
310 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't
311 work here since we are using the raw file descriptor. So, we call lseek()
312 on the fileno(f) before using it. (#60840).

372 - four valid ppm's, eight invalid (matthiasc@poet.de)
373 - one invalid xpm (matthiasc@poet.de)
374 - one valid tga, one invalid (sandmann@daimi.au.dk)
375 - one invalid tiff (sandmann@daimi.au.dk
377 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
379 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
380 fail - detect it when it happens
382 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
385 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
388 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
390 * Makefile.am: don't used BUILT_SOURCES to build marshal
391 files, as in conjunction with stamp files, this can
392 lead to endless rebuilding loops.

442 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
443 function, so that's what I did.

553 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
554 and fix behavior to still subst color if the original image
557 2001-06-04 Havoc Pennington <hp@redhat.com>
559 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
562 2001-06-01 Havoc Pennington <hp@redhat.com>
564 Apply patch from sandmann@daimi.au.dk, with some tweaks.
565 Makes things a bit more robust, and adds test-loaders.c
566 which is good for finding further robustness bugs to fix.
568 * io-tiff.c: Try to work around libtiff suckiness a bit;
569 put a giant thread lock on the whole loader,
570 paranoically check both whether error handlers were called and
571 also whether functions return false. Handle case where width or
572 height is 0. Various cleanups.
574 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
576 (png_error_callback): apparently libpng expects you to longjmp out
579 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
580 (lzw_read_byte): change "Mail jrb if this fails" g_warning
582 (gif_get_lzw): check for out-of-memory
583 (gif_prepare_lzw): catch/report an error
584 (new_context): use try_malloc, since GifContext is nearly 70K
585 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
586 so we don't crash later.
588 * Makefile.am: Add test-loaders
590 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
593 2001-05-29 Darin Adler <darin@eazel.com>
595 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
597 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
599 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
600 fix up bmp decoder to:
601 - adds 16 bpp bmp support (bug #53884)
602 - adds OS/2 1.x format bmp support (bug #54964)
603 - adds 4 bpp RLE compressed bmp support
604 - adds 1 bpp colormap support
605 - fixes negative height (top down) bmp support
607 2001-05-25 Hans Breuer <hans@breuer.org>
609 * gdk_pixbuf.def : reflect Havoc's recent api change
611 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
613 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
616 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
618 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
620 2001-05-04 Havoc Pennington <hp@redhat.com>
622 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
623 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
626 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
627 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
628 confusion of using "src" instead of "p".
629 (pixops_composite_color_nearest): Use a more accurate (and
630 correct, to begin with) compositing method. This cures checks
631 showing through on images with no alpha.
633 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
636 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
638 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
639 area_updated signal to use signed ints. Removed animation-related
642 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
645 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
646 all the pesky details. Remove old frame-based API. Make
647 GdkPixbufAnimation an abstract base class, derived by the loaders.
649 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
651 * Makefile.am (LDADDS): Add $(MATH_LIB).
653 2001-04-18 Havoc Pennington <hp@redhat.com>
655 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
658 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
660 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
661 so we don't try to get <gtk/gtkobject.h> from standard search
664 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
665 add gdk-pixbuf-marshal.list to EXTRA_DIST.
666 take gdk-pixbuf-marshal.h out of _la sources.
668 2001-03-19 Tor Lillqvist <tml@iki.fi>
670 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
672 * gdk_pixbuf.def: Update.
674 * pixbufloader_*.def: Just export the fill_vtable functions now.
676 2001-03-18 Mike Kestner <mkestner@ameritech.net>
678 * make-inline-pixbuf.c (main): Added logic to remove output when
681 2001-03-14 Havoc Pennington <hp@redhat.com>
683 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
684 from gdk-pixbuf-marshal.h, fixes parallel makes.
686 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
688 * test-gdk-pixbuf.c: fixed includes.
690 2001-02-18 Havoc Pennington <hp@pobox.com>
692 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
693 (gdk_pixbuf_get_named_module): prepend underscore
694 (gdk_pixbuf_get_module): prepend underscore
696 2001-02-19 Havoc Pennington <hp@redhat.com>
698 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
700 2001-02-17 Havoc Pennington <hp@pobox.com>
702 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
704 2001-02-07 Alexander Larsson <alexl@redhat.com>
706 * io-xpm.c (free_buffer):
707 Use g_free, since the buffer is allocated with g_try_alloc().
709 2001-02-06 Christophe Merlet <redfox@eikonex.org>
711 * gdk-pixbuf-data.c: Fixes a minor typo.
713 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
715 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
716 we finally need the gobject->gruntime rename.
718 * *.c: scratched calls to g_type_init(), there's simply no point in
719 doing that, use gtk_init().
721 2001-02-01 Havoc Pennington <hp@pobox.com>
723 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
724 in struct to "priv" for C++
726 2001-01-31 Havoc Pennington <hp@pobox.com>
728 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
730 2001-01-26 Havoc Pennington <hp@redhat.com>
732 * gdk-pixbuf-io.c (mname): fix included modules case.
734 2001-01-22 Havoc Pennington <hp@redhat.com>
736 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
737 from gdk_pixbuf_load_module
739 2001-01-22 Havoc Pennington <hp@redhat.com>
741 * Makefile.am: Add built marshaller files to support
742 GdkPixbufLoader signals
744 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
745 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
746 module location, rather than acting as a fallback, because we are
747 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
749 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
751 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
752 from gtk, and add error to close(), because stop_load may do
753 parsing of the image.
755 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
757 * io-*.c: make individual operations static, and add fill_vtable
758 functions which are exported. Fix the collection of type warnings
759 that surfaced, including a number of functions that didn't
760 properly take a GError and some that weren't
761 const-correct. Involved adding error handling for a few loaders.
763 * gdk-pixbuf-io.h: Add error reporting to stop_load function
765 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
766 a function that fills in the GdkPixbufModule vtable, instead of
767 looking up all the image functions individually; this means we
768 can get type safety within modules for the loader functions.
769 Also it means you don't have to keep the statically compiled and
770 GModule versions in sync.
772 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
774 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
776 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
778 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
781 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
783 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
786 2001-01-20 John Harper <jsh@eazel.com>
788 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
789 collision between Xlib's RdBitF.c and io-tiff.c
791 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
794 [ merged from stable gdk-pixbuf module. Untested, but it
795 compiles, and works fine in the stable module ]
797 2001-01-18 Tor Lillqvist <tml@iki.fi>
799 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
800 g_win32_get_package_installation_subdirectory() function. No need
801 to include windows.h.
802 (gtk_win32_get_installation_directory): Remove this then.
804 2001-01-01 Havoc Pennington <hp@redhat.com>
806 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
807 @LIBTOOL_EXPORT_OPTIONS@
809 2000-12-30 Tor Lillqvist <tml@iki.fi>
811 * gdk_pixbuf.def: Update.
813 2000-12-16 Havoc Pennington <hp@pobox.com>
815 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
816 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
817 (gdk_pixbuf_frame_copy): new function
818 (gdk_pixbuf_frame_free): new function
819 (gdk_pixbuf_frame_get_type): new function
820 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
822 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
824 * Makefile.am: Add -avoid-version for all modules.
826 2000-11-13 Havoc Pennington <hp@redhat.com>
828 * io-png.c (png_simple_error_callback): fix error message to not
829 say "save" since it's used for loading
831 2000-11-11 Hans Breuer <Hans@Breuer.Org>
833 * gdk-pixbuf-io.c : Fix all function prototype macros for self
834 contained image handlers (!USE_G_MODULE). Files to save should
835 be opened in binary mode, fopen(s, "wb").
837 * io-xpm.c : added HAVE_UNISTD_H condition
839 2000-11-11 Tor Lillqvist <tml@iki.fi>
841 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
843 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
844 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
845 mktemp() and open()).
847 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
849 2000-11-01 Havoc Pennington <hp@pobox.com>
851 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
852 a pixbuf pointing to a subregion of another pixbuf.
854 2000-10-16 Tor Lillqvist <tml@iki.fi>
856 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
858 2000-10-16 Havoc Pennington <hp@redhat.com>
860 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
861 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
862 add error reporting here also
864 * make-inline-pixbuf.c (main): use GError
866 * io-xpm.c: include unistd.h
868 * gdk-pixbuf-util.c: include string.h
870 * io-*.c: add error reporting
872 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
875 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
877 * gdk-pixbuf-io.h: Add GError** to load_increment and load
880 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
881 a G_FILE_ERROR if we fail to write or close the file.
883 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
884 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
885 the GError naming rules. Add GError** to load functions.
887 2000-10-06 Havoc Pennington <hp@redhat.com>
889 * gdk-pixbuf.h: add GdkPixbufAlphaMode
891 2000-10-06 Havoc Pennington <hp@redhat.com>

919 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
921 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
922 last nights code was still "broken". Should now properly handle
923 all error conditions gracefully.
925 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
927 * gdk-pixbuf/io-pnm.c: Rewrote.

938 2000-08-05 Larry Ewing <lewing@helixcode.com>
940 * gdk-pixbuf/io-tiff.c: stop leaking context->tempname.
942 * gdk-pixbuf/io-xpm.c: same as above.
944 2000-07-26 Michael Meeks <michael@helixcode.com>
946 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
949 2000-07-21 Larry Ewing <lewing@helixcode.com>
951 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
952 xpm at least supports the progressive interface like the one in
953 io-tiff.c. This should be reimplemented as an actual progressive
956 2000-07-19 Jonathan Blandford <jrb@redhat.com>
958 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
960 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
961 meeks to handle errors better.
963 2000-10-07 Tor Lillqvist <tml@iki.fi>

977 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
979 2000-10-05 Havoc Pennington <hp@redhat.com>
981 Pixbuf saving, patch from David Welton.
983 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
984 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h
986 * gdk-pixbuf-i18n.h: Add _() to gdk-pixbuf

998 * gdk-pixbuf.h: Add public save routines; add pixbuf error
1001 * gdk-pixbuf-io.h: Add save function to GdkPixbufModule
1003 2000-10-05 Dan Winship <danw@helixcode.com>
1005 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
1006 all three of these files are the JPEG image loader. (From
1009 2000-10-03 Tor Lillqvist <tml@iki.fi>
1011 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
1012 gdk-pixbuf's version number in the rule for makefile.mingw itself.
1014 * gdk_pixbuf.def: Add new entry points.
1016 2000-09-26 Havoc Pennington <hp@redhat.com>
1018 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
1019 function here, instead of putting it in a private GTK+ file.
1021 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
1022 enum here for the known formats of inlined pixbufs.
1023 Also, #define our file magic here.
1025 2000-06-23 Havoc Pennington <hp@redhat.com>
1027 * make-inline-pixbuf.c: Small program that creates C variable
1028 declarations of inline pixbuf data. This can be read
1029 by gdk_pixbuf_new_from_inline.
1031 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
1032 inline pixbuf data and create a pixbuf from it.
1034 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
1036 2000-09-07 Tor Lillqvist <tml@iki.fi>
1038 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
1041 2000-08-12 Tor Lillqvist <tml@iki.fi>
1043 * gdk_pixbuf.def: Add missing entry point.
1045 2000-08-10 Havoc Pennington <hp@redhat.com>
1047 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
1048 (s/pixbuf_/pixbufloader_)
1050 2000-08-02 Tor Lillqvist <tml@iki.fi>
1056 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1058 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1059 one. Fix names of DLLs to have '-' instead of '_'.
1061 2000-07-31 Elliot Lee <sopwith@redhat.com>
1062 * io-wbmp.c: Some bug fixes - now tested to work.
1064 2000-07-27 Elliot Lee <sopwith@redhat.com>
1066 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1067 gdk_pixbuf_get_named_module() function to facilitate above change
1068 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1069 Implement loader for WBMP format.
1070 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1072 2000-07-23 Tor Lillqvist <tml@iki.fi>
1077 * pixops/makefile.mingw.in
1078 * pixbuf_*.def: New files.
1081 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1083 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1084 New function, to get the GTK+ installation directory from
1085 the Windows Registry, where the installation program
1086 for whatever software includes GTK+ has stored it.
1088 Used to avoid having hardcoding the directory where to look for
1089 loaders. This function is needed by gtk, too, so it should
1090 really be just in one place. Maybe a small static library
1091 one level up from here?
1093 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1094 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1095 Open file in binary mode. This *is* standard C. (No-op on Unix,
1098 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1100 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1101 mktemp() and open().
1102 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1104 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1105 pseudo-op. Conditionalise on __MINGW32__, but probably
1106 should conditionalise on Gas version instead? Or could we
1107 do without .type on all systems?
1109 * pixops/timescale.c: Use g_get_current_time()
1110 instead of gettimeofday().
1112 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1114 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1116 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1118 * gdk-pixbuf.c: Add <string.h> include.
1120 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1122 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1123 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1124 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1125 use g_object_new() instead of g_type_create_instance() which
1126 is a private function for fundamental type implementations.
1128 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1130 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1131 soname scheme for gdk-pixbuf.
1133 2000-06-21 Havoc Pennington <hp@pobox.com>
1135 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1136 (i.e. derivation is not allowed, and there are no virtual methods
1138 (gdk_pixbuf_preinit): Call g_type_init() here.
1139 (gdk_pixbuf_init): Add a user-friendly init function, for users
1140 of standalone gdk-pixbuf
1142 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1143 way GdkPixbufAnimation was done.
1145 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1146 gdk_pixbuf_finalize() from API, since these are broken and don't
1147 make sense with new GObject stuff.
1149 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1151 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1152 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1155 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1157 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1158 so I needed something to warm my thighs. Running plain infinite
1159 loops on your laptop to make it hot is not very much fun. A demo
1160 of the gdk-pixbuf scaling functions is way better, and looks
1163 * configure.in (AC_OUTPUT): Added the demo Makefile.
1165 * Makefile.am (SUBDIRS): Added the demo directory.
1167 2000-06-09 Larry Ewing <lewing@helixcode.com>
1169 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1170 setjmp for the png error handler. It seems setting the error
1171 handling functions does not avoid the jump, and so not calling
1172 setjmp was causing the incremental loader to jump into lala land.
1173 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1174 not sure this one is actually required but the docs say it must be
1175 set for every call to a png_* function.
1176 Also changed the comment to reflect the fact that setting the
1177 error handlers does _not_ avoid the longjmp.
1179 2000-06-06 Larry Ewing <lewing@helixcode.com>
1181 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1182 take frame offest into account when trying to calculate the
1183 animation bbox. Also set the width to the width not the height.
1184 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1185 calculate bbox because now we finally have all the offset
1186 information for each frame.
1188 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
1190 * configure.in: add some gtk parameters to the
1191 GDK_PIXBUF_LIB²S and GDK_PIXBUG_INCLUDEDIR vars. One more
1192 fight in my crusade for strange prefix compile...
1194 2000-05-30 Not Zed <NotZed@HelixCode.com>
1196 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
1197 Initialise the error handler exit routine to our own. Note this
1198 means that every function that accesses the jpeg lib on this
1199 object MUST do a setjmp.
1200 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
1201 lib for handling fatal error.
1202 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
1203 your applications dont quit if there's a jpeg error!
1205 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
1207 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
1208 from Frank de Lange <frank@unternet.org>.
1210 2000-05-09 Darin Adler <darin@eazel.com>
1212 * gdk-pixbuf/test-gdk-pixbuf.c:
1213 Fixed includes to get rid of accidental GNOME dependency.
1215 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
1216 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
1218 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
1220 * configure.in: Bumped version number to 0.8.0.
1222 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
1223 file was not being distributed.
1225 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
1227 2000-05-09 Darin Adler <darin@eazel.com>
1229 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
1230 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
1231 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
1232 formats to 32-bit formats to re-use the high bits of the color values
1233 so that white maps to full white.
1235 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
1237 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
1238 detailed information about the structure and algorithms
1239 of pixops so people can fix it instead of breaking it.
1241 2000-05-04 Darin Adler <darin@eazel.com>
1243 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
1244 (composite_pixel), (composite_line):
1245 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
1246 Now that Owen explained the algorithm, I think I implemented it
1247 right for the cases where the destination pixbuf is not opaque.
1248 The test does seem to confirm it.
1250 2000-05-04 Darin Adler <darin@eazel.com>
1252 * gdk-pixbuf/.cvsignore:
1253 * gdk-pixbuf/Makefile.am:
1254 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
1255 (load_pixel), (simple_composite_test_one),
1256 (simple_composite_test_one_type), (simple_composite_test), (main):
1257 Added some tests of composite to highlight problems in the old
1258 implementation. These tests run without any user interaction.
1259 Just do "make check".
1261 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
1262 (composite_pixel), (composite_line): Fix composite to do a textbook
1263 "A over B" composite. This was clearly the intent, and it was easy
1264 to fix the code to do it. (Note to those that read my earlier tries
1265 at a patch; this version fixes typos that were present in all
1266 my patch attempts. I checked the final version by adding more tests.)
1268 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
1270 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
1271 offset y coordinate accordining to render_y0.
1273 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
1276 2000-04-22 James Henstridge <james@daa.com.au>
1278 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
1279 package to the devel package. The only file installed in bin is
1280 gdk-pixbuf-config, which belongs in -devel. This should allow having
1281 multiple versions of the main gdk-pixbuf package installed.
1283 2000-04-17 Karl Eichwalder <ke@suse.de>
1285 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
1286 Reported by Jens Finke.
1288 2000-04-14 Tomasz K³opczko <kloczek@pld.org.pl>
1290 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
1291 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
1293 2000-04-13 James Henstridge <james@daa.com.au>
1295 * configure.in: when performing the configure check to see if
1296 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
1297 rather than the other way round. Also, call AC_MSG_RESULT in the
1298 even that dynamic modules were not supported.
1300 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
1302 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
1303 hook to the last unref operation.
1305 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
1306 function to set the last unref handler for a pixbuf.
1307 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
1308 It calls the pixbuf's destroy notification function and frees the
1309 GdkPixbuf structure itself.
1310 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
1313 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
1314 for the last unref handler and its user data.
1316 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
1317 g_new0() to allocate the pixbuf.
1319 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
1320 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
1321 was not specifying the `frame' argument.
1323 * gdk-pixbuf/gdk-pixbuf-animation.c
1324 (gdk_pixbuf_animation_get_width): Fixed docstring.
1325 (gdk_pixbuf_animation_get_height): Likewise.
1326 (gdk_pixbuf_animation_get_num_frames): Likewise.
1327 (gdk_pixbuf_animation_get_frames): Likewise.
1329 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
1332 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
1334 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
1336 * doc/tmpl/refcounting.sgml: Updated with the information about
1337 the last unref handler.
1339 * doc/tmpl/*.sgml: Markup tweaks.
1341 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
1342 update the libtool version number for libgnomecanvaspixbuf as
1344 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
1345 as well, or the old ones won't work with the new stuff. Also,
1346 renamed the modules as follows.
1348 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
1349 modules are called "libpixbufloader-<format>.so" instead of
1350 "libpixbuf-<format>.so". They needed renaming so that the new
1351 loaders won't overwrite the old ones; even with the versioning
1352 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
1355 2000-04-12 Paolo Molaro <lupus@debian.org>
1357 * .cvsignore, src/.cvsignore: shut up cvs.
1359 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
1361 Most of this patch is based on a patch by Havoc Pennington
1362 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
1363 remove the libart dependency.
1365 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
1366 (GdkColorspace): New enum that for now only contains
1368 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
1369 notification function.
1370 (GdkInterpType): New num with interpolation types.
1372 * *.[ch]: Replace the libart stuff with our own stuff.
1374 * pixops/*.[ch]: Likewise.
1376 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
1377 declarations of the GdkPixbuf structures.
1379 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
1381 (gdk_pixbuf_get_format): Constify.
1382 (gdk_pixbuf_get_n_channels): Constify.

1387 (gdk_pixbuf_get_height): Constify.
1388 (gdk_pixbuf_get_rowstride): Constify.
1390 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
1393 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
1394 bits_per_sample argument; currently only 8 bits per sample are
1397 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
1399 (gdk_pixbuf_frame_get_x_offset): New accessor.
1400 (gdk_pixbuf_frame_get_y_offset): New accessor.
1401 (gdk_pixbuf_frame_get_delay_time): New accessor.
1402 (gdk_pixbuf_frame_get_action): New accessor.
1404 * gdk-pixbuf/gdk-pixbuf-render.c
1405 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
1406 mask rectangle for pixbufs without an alpha channel, set the
1407 *mask_return to NULL.
1409 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
1411 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
1413 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
1414 preconditions. Maybe we should also check for the colorspace,
1415 bits per pixel, and such.
1416 (gdk_pixbuf_composite): Likewise.
1417 (gdk_pixbuf_composite_color): Likewise.
1418 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
1419 cannot allocate the new pixbuf.
1420 (gdk_pixbuf_composite_color_simple): Likewise.
1422 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
1423 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
1426 * gdk-pixbuf/io-bmp.c: Fix includes.
1428 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
1433 * configure.in: Removed checks for libart.
1435 * gdk-pixbuf/Makefile.am: Removed references to libart.
1436 (noinst_HEADERS): Added gdk-pixbuf-private.h.
1438 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
1439 the version number of the libtool library to indicate that this
1440 definitely is not compatible with the old usage. I know you love
1443 * configure.in: Bumped version number to 0.7.0.
1447 * gdk-pixbuf-config.in (--libs): We no longer require libart.
1449 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
1451 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
1453 2000-04-06 Jonathan Blandford <jrb@redhat.com>
1455 * gdk-pixbuf/testanimation.c (main): add more info to the
1456 testanimation frames.
1458 2000-04-04 Ettore Perazzoli <ettore@helixcode.com>
1460 * gdk-pixbuf/gdk-pixbuf-animation.c
1461 (gdk_pixbuf_animation_get_width): New accessor function.

1464 (gdk_pixbuf_animation_get_frames): New accessor function.
1466 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
1468 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
1469 is private information, and the art_pixbuf will go away soon.
1471 2000-03-31 Mark Crichton <crichton@gimp.org>
1473 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
1474 and gdk_pixbuf_get_artpixbuf accessor functions.
1476 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
1478 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
1479 gboolean instead of int.
1481 2000-03-29 Radek Doulik <rodo@helixcode.com>
1483 * gdk-pixbuf/gdk-pixbuf-animation.c
1484 (gdk_pixbuf_animation_new_from_file): same as below
1486 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
1487 height in GdkPixbufAnimation
1489 2000-03-28 Radek Doulik <rodo@helixcode.com>
1491 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
1492 context->frame_done_func and context->anim_done_func to make
1493 progressive animation loading work
1495 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1496 added priv->pixbuf = NULL as pixbuf is now in frame (and to make
1497 gdk_pixbuf_loader_prepare happy)
1498 (gdk_pixbuf_loader_frame_done): update animation bbox
1500 * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to
1503 2000-03-27 Radek Doulik <rodo@helixcode.com>
1505 * gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width
1506 instead of width and height
1508 2000-03-27 Owen Taylor <otaylor@redhat.com>
1510 * gdk-pixbuf/pixops/pixops.c: Fix problem with
1511 precendence of >> and & which was keeping composite_color
1512 from working with non-gray images.
1514 2000-03-08 Jonathan Blandford <jrb@redhat.com>
1516 * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context.
1517 (gdk_pixbuf__gif_image_load_animation): free the context.
1519 2000-03-06 Arjan van de Ven <arjan@fenrus.demon.nl>
1521 * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a
1522 mis-interpretation of the Microsoft documentation. Now
1523 it can load .BMP files that are not generated by The Gimp
1526 2000-03-01 Mark Crichton <crichton@gimp.org>
1528 * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
1529 fix the last auto* build bug (where we have libart, but no
1532 * gdk-pixbuf/Makefile.am: Same.
1534 2000-02-28 Matt Wilson <msw@redhat.com>
1536 * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,
1537 s/unsigned short/guint16/g, s/unsigned char/guint8/g
1539 2000-02-26 Federico Mena Quintero <federico@helixcode.com>
1541 * README: We don't require libgif/ungif nor libXpm.
1543 * NEWS: This was outdated, so updated it.
1545 2000-02-25 Federico Mena Quintero <federico@helixcode.com>
1547 * gdk-pixbuf.m4: Use the correct name for
1548 gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing
1551 2000-02-21 Federico Mena Quintero <federico@helixcode.com>
1553 * configure.in (GDK_PIXBUF_MINOR): Bumped version number to 0.6.0.
1555 * doc/compiling.sgml: New appendix documenting the gdk-pixbuf
1556 library's particular options to configure.in.
1558 * doc/gdk-pixbuf.sgml: Include compiling.sgml appendix via an
1561 * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml.
1563 * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment):
1564 Fixed typo in prototype name.
1566 * configure.in: Changed duplicated AC_MSG_CHECKING message to
1567 something more meaningful; now it is "checking whether dynamic
1570 * gdk-pixbuf/pixops/Makefile.am (noinst_PROGRAMS): Do not install
1571 the timescale program.
1573 Integrated Miguel de Icaza's <miguel@gnu.org> patch for optionally
1574 creating a single static library with all the image format modules

1943 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
1944 animation functions here.
1945 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
1946 animation if the loader does not support multiframe loading and
1947 the single-frame load returned NULL. Check that the filename is
1948 not NULL. Updated inline documentation.

1950 (gdk_pixbuf_animation_unref): New function.
1951 Removed gdk_pixbuf_animation_destroy() in favor of reference

1987 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
1988 set to NULL here (specifically context->animation) was not being
1989 set to NULL. use g_new0() to alloc the struct.
1991 1999-12-20 Jonathan Blandford <jrb@redhat.com>
1993 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
1994 correctly. Progressive loading needs some work, but that all
1995 needs doing from the gdk-pixbuf-loader end, not here.
1997 1999-12-17 Jonathan Blandford <jrb@redhat.com>
1999 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2000 moved the file here. It seems natural to put this function here,
2001 as that's where the gdk_pixbuf_new_from_file function is, but it's
2002 still a little convoluted. The source files might be played with
2005 1999-12-14 Jonathan Blandford <jrb@redhat.com>

2051 Filled in body of function.
2052 (rgbconvert): Added GdkColormap parameter, and to all conversion
2054 (convert_real_slow): New function - should convert ANY visual/data
2055 format properly, but it aint fast. Used as a fallback when an
2056 optimised routine wont match.
2057 (rgbconvert): Do very specific tests on the data format to verify
2058 properly if the optimised version will do, otherwise use the
2059 fallback function for all other data formats.
2061 * gdk-pixbuf/Makefile.am: Re-enabled building of
2062 textpixbuf-drawable.
2064 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use

2077 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2078 checks and API definition. The body needs filling in and it needs
2079 to do the Right Thing(tm) for pixmaps plus the given colormap and
2080 windows and their own colormaps.
2082 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2083 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.

2120 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2121 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2122 want, send me a patch to do the conditional stuff properly.
2123 Otherwise, please read the GNOME Programming Guidelines,
2124 especially the "CVS policies" section.
2126 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>

2156 * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to
2157 explain this function better.
2159 1999-12-02 Federico Mena Quintero <federico@redhat.com>
2161 Source files moved from src/ to gdk-pixbuf/, to be consistent with

2234 * doc/tmpl/util.sgml: Documentation for the utility functions.
2236 1999-11-29 Owen Taylor <otaylor@redhat.com>
2238 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
2239 Keep the mask around until after we draw ... since
2240 the GC changes aren't flushed to the X server until we
2241 draw, destroying it before that may result in BadPixmap
2244 1999-11-30 Havoc Pennington <hp@pobox.com>
2246 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
2248 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
2250 1999-11-29 Federico Mena Quintero <federico@redhat.com>
2252 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
2253 should be made conditional, not blindly commented out.
2255 1999-11-29 Jonathan Blandford <jrb@redhat.com>
2257 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
2258 handle .ico files. Cool.
2260 1999-11-24 Jonathan Blandford <jrb@redhat.com>
2262 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
2265 1999-11-24 James Henstridge <james@daa.com.au>
2267 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
2268 top builddir rather than src. This still builds fine, and does not
2269 get gtk-doc into an infinite loop when trying to find all the source
2272 1999-11-23 Jonathan Blandford <jrb@redhat.com>
2274 * Removed #PRAGMA } from headers. Also, make compile if you don't
2275 have it installed, already.
2277 1999-11-22 Federico Mena Quintero <federico@redhat.com>
2279 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
2280 temporary buffer to the size of the interesction of the bounding
2281 box and the expose area, not the whole expose area. This speeds
2284 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
2285 not paint black on the mask, since we already cleared it in a
2286 single gdk_draw_rectangle() operation.
2288 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
2290 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
2292 1999-11-22 Havoc Pennington <hp@pobox.com>
2294 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
2295 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
2296 dependencies to LIBADD variables for loadable modules. Necessary
2297 for a Java dynamic loading thing to be able to figure it out.
2299 1999-11-22 Havoc Pennington <hp@pobox.com>
2301 * src/io-png.c (image_load_increment): Call the update_area
2302 callback depending on the number of rows loaded in this increment.
2304 * src/testpixbuf.c (main): slow down the progressive load demo
2306 1999-11-16 Havoc Pennington <hp@pobox.com>
2308 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
2310 1999-11-22 Jonathan Blandford <jrb@redhat.com>
2312 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
2313 for srcdir != buildir != . Beats me why; I can't figure it out.
2314 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
2316 1999-11-21 Jonathan Blandford <jrb@redhat.com>
2318 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
2319 <arjan@fenrus.demon.nl>
2321 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2323 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
2324 Rework/reorder of the code. Each case has been separated into
2325 another function; its big but it should be quick.
2326 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
2327 opaque alpha information. Not all depths/formats have been
2328 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
2330 1999-11-17 Larry Ewing <lewing@gimp.org>
2332 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
2333 implement the bounds method correctly.
2334 (compute_viewport_affine): compute the affine need to fit the
2335 image within the viewport given by the args.
2336 (compute_render_affine): call compute_viewport_affine.
2338 1999-11-16 Havoc Pennington <hp@pobox.com>
2340 * src/gdk-pixbuf-drawable.h: Use includes from the current
2341 directory, not the system directory.
2343 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
2345 * src/testpixbuf-drawable.c: use includes from the current directory
2346 rather then from the system include directory as gdk-pixbuf
2347 includes are not yet installed when this is compiled.
2349 1999-11-13 Cody Russell <bratsche@dfw.net>
2350 * src/testpixbuf-drawable.c: Added a test program for drawable
2353 * src/Makefile.am: Build testpixbuf-drawable.
2355 1999-11-12 Cody Russell <bratsche@dfw.net>
2357 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.

2368 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2370 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
2373 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
2374 correctly. Patch from Arjan to do so.
2376 1999-11-10 Michael Fulbright <drmike@redhat.com>
2378 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
2381 * src/testpixbuf.c: Added final queued draw when done loading image.
2383 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2385 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
2388 1999-11-10 Federico Mena Quintero <federico@redhat.com>
2390 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
2393 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2395 * src/io-png.c: Fixed some incompatible pointer initializations.
2397 * src/io-jpeg.c (image_load_increment): Remove unused variable.
2399 1999-11-09 Michael Fulbright <drmike@redhat.com>
2401 * src/testpixbuf.c: Fixed it to use timeout to read from file
2402 for progressive loading. Set TBF_KBPS=n, where n is the number of
2403 kilobytes/second to simulate in downloading. n has to be an integer.
2405 * src/io-jpeg.c: Slight cosmetic cleanup.
2407 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
2408 PBM loading has a similar problem and will address tomorrow.
2410 1999-11-09 Havoc Pennington <hp@pobox.com>
2412 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
2413 gdk-pixbuf-drawable stuff.
2415 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2417 * configure.in: Bumped version number to 0.4.
2419 1999-11-09 Michael Fulbright <drmike@redhat.com>
2421 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
2422 all types of PNM files now.
2424 * src/io-jpeg.c (image_load_increment): Figured out problem with
2425 loading Progressive JPEG's progressively (say that 10 times fast).
2426 Currently for Progressive JPEG's the entire image is loaded before
2427 it is displayed. libjpeg supports a fancier mechanism which I may
2430 With these changes all JPEG formats appear to load properly for me.
2432 1999-11-08 Jonathan Blandford <jrb@redhat.com>
2434 * src/io-ras.c (image_load_increment): Final patch from Arjan.
2435 Seems to do progressive loading.
2437 1999-11-08 Michael Fulbright <drmike@redhat.com>
2439 * src/io-pnm.c image_load (): Fixed so we do not create a separate
2440 pixel buffer when reading in image - we reuse the pixel data in
2441 the GdkPixbuf structure instead.
2443 1999-11-08 Michael Fulbright <drmike@redhat.com>
2445 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
2446 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
2447 I can't seem to find a utility to convert into this format.
2448 Next is to add progressive loading support for the PNM format.
2450 1999-11-07 Federico Mena Quintero <federico@redhat.com>
2452 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
2453 of the width, height, x, and y setting and pixels arguments.
2455 1999-11-05 Jonathan Blandford <jrb@redhat.com>
2457 * src/io-ras.c (image_load): third patch. Now it seems to load.
2459 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
2460 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
2462 * src/io-ras.c (image_load): new file from Arjan van de Ven
2463 <arjan@fenrus.demon.nl> to begin the ras loader.
2465 1999-11-05 Federico Mena Quintero <federico@redhat.com>
2467 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
2468 for internal use only.
2470 * doc/gdk-pixbuf.sgml: Likewise.
2472 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
2474 1999-11-05 Michael Fulbright <drmike@redhat.com>
2476 * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
2477 files from a file. Next step is support for ASCII files, and
2478 then incremental loading.
2480 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2482 * Makefile.am: Added doc to SUBDIRS.
2484 1999-11-04 Michael Fulbright <drmike@redhat.com>
2486 * src/io-jpeg.c: Prettied up code slightly.
2487 * src/io-pnm.c: Start of pnm loader (from file and progressively).
2488 Doesn't do much yet (will finish tomorrow).
2489 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
2491 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2493 * doc/tmpl/rendering.sgml: Populated.
2495 * doc/Makefile.am: Added the template files.
2497 1999-11-04 Havoc Pennington <hp@pobox.com>
2499 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
2500 docs, explain what a dither offset is for.
2501 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
2502 this function vs. gdk_pixbuf_render_to_drawable().
2504 1999-11-04 Havoc Pennington <hp@pobox.com>
2506 * configure.in: Use libart-config correctly; find gnome-config
2507 separately. Fix GNOME_LIBS to be correct in "no gnome installed
2510 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
2513 Patch untested in the inside-gnome-libs case, I need to commit
2514 then check out to the gnome-libs I'm using.
2516 1999-11-04 Michael Fulbright <drmike@redhat.com>
2518 * src/io-jpeg.c (image_begin_load): Add update_func callback.
2519 * src/io-jpeg.c (image_load_increment): Call updated callback when
2520 new graphic data decoded.
2522 1999-11-04 Jonathan Blandford <jrb@redhat.com>
2524 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_update): handle the
2526 * src/io-png.c (image_begin_load): add a update_func callback.
2527 * src/io-gif.c (image_begin_load): add a update_func callback.
2528 (gif_get_lzw): added the update_func ability

2532 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2534 * doc/tmpl/gdk-pixbuf.sgml: Populated.
2536 * doc/tmpl/refcounting.sgml: Populated.
2538 * doc/tmpl/file-loading.sgml: Populated.
2540 * src/gdk-pixbuf.c: Added documentation comments.

2562 1999-11-03 Michael Fulbright <drmike@redhat.com>
2564 * src/io-jpeg.c (image_load_increment): Further removal of
2565 bugginess in local buffering code. Handles grayscale jpegs
2568 * src/io-jpeg.c (image_load_stop): Was freeing local context
2569 for jpeg library before calling jpeg_decompres_finish ().
2571 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2573 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
2575 (gif_get_lzw): set the transparency to the right val.
2577 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2579 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
2580 Initiailize the x and y fields.
2581 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
2582 (PixbufPrivate): Renamed need_size_update to need_xform_update.
2583 (recompute_bounding_box): Do not use temporary values.
2585 1999-11-03 Jonathan Blandford <jrb@redhat.com>

2595 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
2596 render_affine calculation for x,y offsets.
2597 (gnome_canvas_pixbuf_set_arg): add x,y args.
2598 (gnome_canvas_pixbuf_get_arg): add x,y args.
2599 (recompute_bounding_box): simply code using ArtDrect and the
2600 render_affine. Removed compute_xform_vectors as it was no longer
2603 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2605 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
2606 doofus. Return a distance, not a boolean, for opaque images.
2608 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
2609 rounding of bounding box coordinates.
2610 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
2611 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
2613 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2615 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
2617 1999-11-03 Michael Fulbright <drmike@redhat.com>
2619 * src/io-jpg.c (image_load_increment): Fixed code which moved
2620 buffer around as new data comes in to work properly. JPEG progressive
2621 loading should be working now except for grayscale JPEG's, which I
2622 will look into next.
2624 1999-11-03 <sopwith@redhat.com>
2625 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
2626 Also put dot printing back in.
2628 1999-11-03 <jrb@redhat.com>
2630 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
2633 1999-11-02 Cody Russell <bratsche@dfw.net>
2634 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
2635 if part of the requested image is offscreen, rather than clipping
2638 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2640 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
2641 for interlacing and progressive loading.
2643 1999-11-02 Cody Russell <bratsche@dfw.net>
2644 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
2645 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
2647 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2649 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
2650 It's a little slow though. )-:
2652 1999-11-02 Elliot Lee <sopwith@redhat.com>
2653 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
2654 write/load_increment operations const-correct.
2656 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2658 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
2659 Implemented the ::point() method. We do a simple containment test
2660 instead of a full distance calculation since the canvas is going
2661 to change to that scheme, anyways.
2663 1999-11-02 Elliot Lee <sopwith@redhat.com>
2665 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
2666 that are read from the input file.
2668 1999-11-02 Larry Ewing <lewing@gimp.org>
2670 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
2672 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
2675 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2677 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
2678 affine computation code from ::draw() to here, since it is needed
2679 by ::point() as well.
2681 1999-11-02 Elliot Lee <sopwith@redhat.com>
2683 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
2684 three functions, and eliminate duplication of code from write()
2685 and close(). Also fix bug where the 128-byte header was being
2688 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2689 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
2690 bounding box computation.
2692 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2694 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
2695 Drawing affines seem to work. Bounding box is fubared. ::point()
2696 is not implemented. This is a work in progress.
2698 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
2701 * configure.in: Sigh. We need to link in libgnomeui for the
2702 canvas stuff. This mess will disappear when gdk-pixbuf gets
2703 folded into gnome-libs.
2705 1999-10-30 Jonathan Blandford <jrb@redhat.com>
2707 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
2708 the right size, at a minimum, even if the image is squished and
2710 (ReadImage): lets get the offset right. This will let transparent
2713 1999-10-29 Michael Fulbright <drmike@redhat.com>
2715 * src/io-jpeg.c: image_load_increment(): Fixed bug when
2716 image width was not a multiple of 4 - always use the
2717 gdk_pixbuf rowstride to increment pointers!
2719 1999-10-29 Michael Fulbright <drmike@redhat.com>
2721 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
2722 Currently does not handle either progressive jpeg files (jpeg
2723 files with multiple scans at different quality settings), but
2724 I plan on adding this support soon. These are fairly rare in
2725 my experience, so it shouldn't slow people down too much.
2726 Grayscale jpegs also don't work but that should be easy to fix.
2728 1999-10-29 Michael Fulbright <drmike@redhat.com>
2730 * src/testpixbuf.c: Added title to windows so you can identify
2731 progressive and file windows.
2733 1999-10-29 Michael Fulbright <drmike@redhat.com>
2735 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
2736 load the image handler when we determine the image type.
2738 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
2739 previously static function load_image_handler () to
2740 a public function gdk_pixbuf_load_module (). It is needed in
2741 gdk-pixbuf-loader.c to load image handler modules. This function
2742 is different from gdk_pixbuf_get_module (), which only returns
2743 a reference to the required handler, because it actually loads
2744 the handler into memory. Both actions should possibly be combined
2745 in a convenience function since one w/o the other doesn't seem to
2748 1999-10-28 Jonathan Blandford <jrb@redhat.com>
2750 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a

2755 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
2756 function to render a portion of a pixbuf to a drawable. Ignores
2757 alpha information and takes in a GC.
2758 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
2759 portion of a pixbuf to a drawable. It automatically creates a GC
2760 and a clipping mask for alpha pixbufs.
2762 1999-10-28 Jonathan Blandford <jrb@redhat.com>
2764 * src/gdk-pixbuf.h: turned convenience macros into convenience
2765 functions so some error checking could be added.
2767 * src/io-tiff.c (image_load_increment): started work on the tiff
2768 non-incremental loader.
2769 (image_begin_load): Finished the incremental loader.

2779 function to threshold a pixbuf's alpha channel into a bitmap.
2781 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
2782 contemplate future extensions to ArtPixBuf's formats.
2784 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
2786 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
2787 macros to fetch the ArtPixBuf's fields.
2789 1999-10-27 Havoc Pennington <hp@pobox.com>

2797 1999-10-27 Havoc Pennington <hp@pobox.com>
2799 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
2800 properly whether the XPM module has already been loaded
2801 (gdk_pixbuf_new_from_file): Check properly if loader module
2802 was already loaded (was checking if load symbol was present
2803 in order to decide whether to re-load; should check module !=
2804 NULL, then load != NULL)
2805 (image_handler_load): Check in present working directory,
2806 makes it easier to debug for now
2807 (file_formats): This array initializer was seriously on crack,
2808 was assigning a function pointer to a GModule*
2810 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
2812 1999-10-27 Havoc Pennington <hp@pobox.com>

2820 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
2821 GdkPixbufLoader, not a GtkObject.
2822 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
2823 (gdk_pixbuf_loader_get_type): Documented.
2824 (gdk_pixbuf_loader_class_init): Initialize the parent class
2826 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
2827 class destroy function.
2828 (gdk_pixbuf_loader_new): Documented.
2829 (gdk_pixbuf_loader_finalize): Call the parent class finalize
2831 (gdk_pixbuf_loader_write): Use size_t for count.
2833 1999-10-27 Michael Fulbright <drmike@redhat.com>
2835 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
2836 logic so we only try to close loader if it wasn't previously closed.
2838 1999-10-27 Michael Fulbright <drmike@redhat.com>
2840 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of

2867 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
2869 1999-10-22 Havoc Pennington <hp@pobox.com>
2871 * src/io-xpm.c (mem_buffer): Clean up stupid
2872 increment-inside-array-dereference thing
2874 * src/testpixbuf.c: Add XPM data tests.
2876 * src/io-xpm.c: Make the XPM data buffer const, fix const
2877 correctness throughout the code.
2879 1999-10-22 Havoc Pennington <hp@pobox.com>

2889 function, loads pixbuf from xpm data
2890 (image_handler_load): Add g_return_if_fail() to ensure the same
2891 module isn't loaded twice. Add g_module_symbol() to scan for XPM
2894 1999-10-22 Federico Mena Quintero <federico@redhat.com>
2896 * src/io-png.c (image_load): Patch from Kristian Hogsberg
2897 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
2898 buffers; the rows can be read in directly into the main pixel
2901 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2903 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
2905 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2907 * configure.in: Bumped version number to 0.3.
2909 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
2910 version number for the library.
2912 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2914 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
2915 all memory management of the buffer is done by libart.
2917 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
2918 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
2920 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
2921 terms of the libart functions. Removed the old code.
2923 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
2924 symbols. Saving will not be implemented in GdkPixbuf.
2926 * src/io-gif.c: Removed the saving stub.
2927 (image_load): Fixed memory management to fail gracefully if we run
2928 out of memory while loading the image. Close the gif file when we
2929 are done. This still needs more error handling for the DGif
2932 * src/io-jpeg.c (image_load): Some robustness fixes.
2934 * src/io-png.c: Removed the saving stuff.
2935 (image_load): Some memory management fixes.

2945 * autogen.sh: use subautogen.sh
2947 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2949 * src/*: Reindented to use the GNOME Indentation. Renamed
2950 GdkPixBuf to GdkPixbuf, for consistency with the function names
2951 (and it is also easier to type) :-)
2953 1999-10-18 Havoc Pennington <hp@pobox.com>
2955 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
2957 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
2959 1999-10-18 Havoc Pennington <hp@pobox.com>
2961 * Makefile.am (SUBDIRS): Remove "macros"
2963 * configure.in: Don't use GNOME_INIT, handle case where we are
2964 inside gnome-libs. AM_PATH_GTK for the GIF test
2966 * src/Makefile.am: Change flags to work without libgnomeui,
2967 comment out testpixbuf for now
2969 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2971 * configure.in: Use $GTK_LIBS as the extra libs when checking for
2972 libgif/libungif, as they need the X libraries. Fixes bug #2472.
2974 1999-10-10 Cody Russell <bratsche@dfw.net>
2975 * src/gdk-pixbuf-drawable.c: core function now determines whether
2976 the requested geometry is on screen or not, and if some is not
2977 then the request is clamped to geometry that is on the screen.
2979 Changed 'pixbuf' to 'art_pixbuf' in core function.
2981 1999-10-08 Michael Fulbright <drmike@redhat.com>
2983 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

2988 1999-10-07 Cody Russell <bratsche@dfw.net>
2989 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
2990 them, but I wrote them).
2992 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
2995 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
2996 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.
2998 * src/gdk-pixbuf-drawable.c: Added #include "gdk-pixbuf-drawable.h"
3001 * src/gdk-pixbuf-drawable.[ch]: Changed functions to return
3002 GdkPixBuf* instead of ArtPixBuf*.

3016 * src/io-tiff.c (image_load): ditto + fix leak
3018 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
3019 crashes this module ( add warning :-)
3021 * src/io-bmp.c (image_load): ditto.
3023 * src/io-gif.c (image_load): ditto.
3025 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
3027 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
3028 it doesn't crash scaling with alpha.
3030 1999-09-17 Federico Mena Quintero <federico@redhat.com>
3032 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
3034 * src/io-gif.c (image_load): Likewise.
3036 * src/io-jpeg.c (image_load): Likewise.

3053 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
3054 to unallocated memory (row_ptr), and fixed its type as well. Take
3055 into account the ArtPixbuf's rowstride when assigning the row
3058 * src/gdk-pixbuf.c: Fixup includes.
3060 * src/gdk-pixbuf-io.c: Likewise.
3062 Sat Jul 31 19:19:47 CEST 1999

3069 * src/io-png.c (image_save): Added PNG saving function
3071 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
3072 image_save(GdkPixBuf *p, FILE *f, ...)
3075 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
3077 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3078 require extra libraries if we actually have those libraries.
3080 1999-07-23 Richard Hestilow <hestgray@ionet.net>
3082 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
3083 * gdk_pixbufConf.sh.in: Added for gnome-config
3085 * configure.in: Modified to generate gdk_pixbufConf.sh
3087 1999-07-20 Mark Crichton <crichton@gimp.org>
3089 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3090 calculation needs to be done.
3092 1999-07-18 Larry Ewing <lewing@gimp.org>
3097 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3098 error cases but one or two in the common case. There are probably
3099 a few small ones left.
3101 1999-07-18 Mark Crichton <crichton@gimp.org>
3103 * configure.in: removed version.h.
3105 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
3108 1999-07-17 Mark Crichton <crichton@gimp.org>
3110 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
3111 (gdk_pixbuf_rotate): Added pixbuf rotation code.

3117 1999-07-16 Larry Ewing <lewing@gimp.org>
3119 * src/testpixbuf.c (expose_func): reverted the expose everything
3120 changes, I'm not sure why these went in.
3121 (config_func): bring this up to date with the new pixbuf_scale
3124 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3125 loading code so that poeple can diagnose problems better.
3127 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3128 no longer allocates a new pixbuf, which make things nicer for the
3129 rest of the code. Unfortunately there is still a problem with
3130 scaling rgba images.
3132 1999-07-16 Mark Crichton <crichton@gimp.org>
3134 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3135 calls gdk_pixbuf_scale. However, something is not working.
3136 N.B.: current pixmap is now stored in user_data with a key of
3139 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
