210 * gdk-pixbuf.h, gdk-pixdata.c: Rename gdk_pixbuf_new_from_stream()
211 back to gdk_pixbuf_new_from_inline(). Rework docs to try

216 * gdk-pixbuf/gdk-pixbuf-io.c
217 * gdk-pixbuf/gdk-pixbuf-private.h
218 * gdk-pixbuf/gdk-pixbuf.c

252 Thu Sep 20 17:22:48 2001 Owen Taylor <otaylor@redhat.com>
254 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
255 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't
256 work here since we are using the raw file descriptor. So, we call lseek()
257 on the fileno(f) before using it. (#60840).
259 2001-09-20 James Henstridge <james@daa.com.au>
261 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,
262 so that flags types are registered as flags rather than enums (not

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

278 2001-09-17 Matt Wilson <msw@redhat.com>

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

376 error if buffer allocation fails.
377 * io-ico.c: Make .ICO loader more robust.
378 All of these are due to sandmann@daimi.au.dk (#50187)

382 * pixops/pixops.c: applied some simple but effective optimizations
383 to pixops_composite_nearest() and pixops_composite_color_nearest().
385 2001-08-07 Sven Neumann <sven@gimp.org>
387 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
388 function, so that's what I did.
390 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
392 * gdk-pixdata.c: Fix a typo.
394 2001-07-30 Hans Breuer <hans@breuer.org>

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

510 Makes things a bit more robust, and adds test-loaders.c
511 which is good for finding further robustness bugs to fix.
513 * io-tiff.c: Try to work around libtiff suckiness a bit;
514 put a giant thread lock on the whole loader,
515 paranoically check both whether error handlers were called and
516 also whether functions return false. Handle case where width or
517 height is 0. Various cleanups.

554 * gdk_pixbuf.def : reflect Havoc's recent api change
556 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
558 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
561 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
563 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
565 2001-05-04 Havoc Pennington <hp@redhat.com>
567 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
568 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
571 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
572 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
573 confusion of using "src" instead of "p".
574 (pixops_composite_color_nearest): Use a more accurate (and
575 correct, to begin with) compositing method. This cures checks
576 showing through on images with no alpha.
578 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
581 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
583 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
584 area_updated signal to use signed ints. Removed animation-related
587 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
590 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
591 all the pesky details. Remove old frame-based API. Make
592 GdkPixbufAnimation an abstract base class, derived by the loaders.
594 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
596 * Makefile.am (LDADDS): Add $(MATH_LIB).
598 2001-04-18 Havoc Pennington <hp@redhat.com>
600 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
603 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
605 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
606 so we don't try to get <gtk/gtkobject.h> from standard search
609 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
610 add gdk-pixbuf-marshal.list to EXTRA_DIST.
611 take gdk-pixbuf-marshal.h out of _la sources.
613 2001-03-19 Tor Lillqvist <tml@iki.fi>
615 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
617 * gdk_pixbuf.def: Update.
619 * pixbufloader_*.def: Just export the fill_vtable functions now.
621 2001-03-18 Mike Kestner <mkestner@ameritech.net>
623 * make-inline-pixbuf.c (main): Added logic to remove output when
626 2001-03-14 Havoc Pennington <hp@redhat.com>
628 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
629 from gdk-pixbuf-marshal.h, fixes parallel makes.
631 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
633 * test-gdk-pixbuf.c: fixed includes.
635 2001-02-18 Havoc Pennington <hp@pobox.com>
637 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
638 (gdk_pixbuf_get_named_module): prepend underscore
639 (gdk_pixbuf_get_module): prepend underscore
641 2001-02-19 Havoc Pennington <hp@redhat.com>
643 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
645 2001-02-17 Havoc Pennington <hp@pobox.com>
647 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
649 2001-02-07 Alexander Larsson <alexl@redhat.com>
651 * io-xpm.c (free_buffer):
652 Use g_free, since the buffer is allocated with g_try_alloc().
654 2001-02-06 Christophe Merlet <redfox@eikonex.org>
656 * gdk-pixbuf-data.c: Fixes a minor typo.
658 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
660 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
661 we finally need the gobject->gruntime rename.
663 * *.c: scratched calls to g_type_init(), there's simply no point in
664 doing that, use gtk_init().
666 2001-02-01 Havoc Pennington <hp@pobox.com>
668 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
669 in struct to "priv" for C++
671 2001-01-31 Havoc Pennington <hp@pobox.com>
673 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
675 2001-01-26 Havoc Pennington <hp@redhat.com>
677 * gdk-pixbuf-io.c (mname): fix included modules case.
679 2001-01-22 Havoc Pennington <hp@redhat.com>
681 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
682 from gdk_pixbuf_load_module
684 2001-01-22 Havoc Pennington <hp@redhat.com>
686 * Makefile.am: Add built marshaller files to support
687 GdkPixbufLoader signals
689 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
690 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
691 module location, rather than acting as a fallback, because we are
692 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
694 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
696 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
697 from gtk, and add error to close(), because stop_load may do
698 parsing of the image.
700 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
702 * io-*.c: make individual operations static, and add fill_vtable
703 functions which are exported. Fix the collection of type warnings
704 that surfaced, including a number of functions that didn't
705 properly take a GError and some that weren't
706 const-correct. Involved adding error handling for a few loaders.
708 * gdk-pixbuf-io.h: Add error reporting to stop_load function
710 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
711 a function that fills in the GdkPixbufModule vtable, instead of
712 looking up all the image functions individually; this means we
713 can get type safety within modules for the loader functions.
714 Also it means you don't have to keep the statically compiled and
715 GModule versions in sync.
717 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
719 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
721 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
723 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
726 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
728 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
731 2001-01-20 John Harper <jsh@eazel.com>
733 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
734 collision between Xlib's RdBitF.c and io-tiff.c
736 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
739 [ merged from stable gdk-pixbuf module. Untested, but it
740 compiles, and works fine in the stable module ]
742 2001-01-18 Tor Lillqvist <tml@iki.fi>
744 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
745 g_win32_get_package_installation_subdirectory() function. No need
746 to include windows.h.
747 (gtk_win32_get_installation_directory): Remove this then.
749 2001-01-01 Havoc Pennington <hp@redhat.com>
751 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
752 @LIBTOOL_EXPORT_OPTIONS@
754 2000-12-30 Tor Lillqvist <tml@iki.fi>
756 * gdk_pixbuf.def: Update.
758 2000-12-16 Havoc Pennington <hp@pobox.com>
760 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
761 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
762 (gdk_pixbuf_frame_copy): new function
763 (gdk_pixbuf_frame_free): new function
764 (gdk_pixbuf_frame_get_type): new function
765 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
767 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
769 * Makefile.am: Add -avoid-version for all modules.
771 2000-11-13 Havoc Pennington <hp@redhat.com>
773 * io-png.c (png_simple_error_callback): fix error message to not
774 say "save" since it's used for loading
776 2000-11-11 Hans Breuer <Hans@Breuer.Org>
778 * gdk-pixbuf-io.c : Fix all function prototype macros for self
779 contained image handlers (!USE_G_MODULE). Files to save should
780 be opened in binary mode, fopen(s, "wb").
782 * io-xpm.c : added HAVE_UNISTD_H condition
784 2000-11-11 Tor Lillqvist <tml@iki.fi>
786 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
788 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
789 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
790 mktemp() and open()).
792 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
794 2000-11-01 Havoc Pennington <hp@pobox.com>
796 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
797 a pixbuf pointing to a subregion of another pixbuf.
799 2000-10-16 Tor Lillqvist <tml@iki.fi>
801 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
803 2000-10-16 Havoc Pennington <hp@redhat.com>
805 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
806 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
807 add error reporting here also
809 * make-inline-pixbuf.c (main): use GError
811 * io-xpm.c: include unistd.h
813 * gdk-pixbuf-util.c: include string.h
815 * io-*.c: add error reporting
817 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
820 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
822 * gdk-pixbuf-io.h: Add GError** to load_increment and load
825 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
826 a G_FILE_ERROR if we fail to write or close the file.
828 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
829 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
830 the GError naming rules. Add GError** to load functions.
832 2000-10-06 Havoc Pennington <hp@redhat.com>
834 * gdk-pixbuf.h: add GdkPixbufAlphaMode
836 2000-10-06 Havoc Pennington <hp@redhat.com>

864 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
866 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
867 last nights code was still "broken". Should now properly handle
868 all error conditions gracefully.
870 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
872 * gdk-pixbuf/io-pnm.c: Rewrote.

883 2000-08-05 Larry Ewing <lewing@helixcode.com>
885 * gdk-pixbuf/io-tiff.c: stop leaking context->tempname.
887 * gdk-pixbuf/io-xpm.c: same as above.
889 2000-07-26 Michael Meeks <michael@helixcode.com>

894 2000-07-21 Larry Ewing <lewing@helixcode.com>
896 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
897 xpm at least supports the progressive interface like the one in
898 io-tiff.c. This should be reimplemented as an actual progressive
901 2000-07-19 Jonathan Blandford <jrb@redhat.com>
903 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
905 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
906 meeks to handle errors better.
908 2000-10-07 Tor Lillqvist <tml@iki.fi>
911 * pixbufloader_jpeg.def
912 * pixbufloader_png.def: Add new entry points.
914 * makefile.mingw.in: Use libintl.
916 2000-10-06 Havoc Pennington <hp@redhat.com>
918 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
919 consistent with gdk_pixbuf_loader_new_with_type().
920 Return runtime error if a module is missing.
922 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
924 2000-10-05 Havoc Pennington <hp@redhat.com>
926 Pixbuf saving, patch from David Welton.
928 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
929 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h
931 * gdk-pixbuf-i18n.h: Add _() to gdk-pixbuf

938 (gdk_pixbuf_savev): Implement pixbuf saving routines
940 * gdk-pixbuf.c (gdk_pixbuf_error_quark): pixbuf error quark
943 * gdk-pixbuf.h: Add public save routines; add pixbuf error
946 * gdk-pixbuf-io.h: Add save function to GdkPixbufModule
948 2000-10-05 Dan Winship <danw@helixcode.com>
950 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
951 all three of these files are the JPEG image loader. (From
954 2000-10-03 Tor Lillqvist <tml@iki.fi>
956 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
957 gdk-pixbuf's version number in the rule for makefile.mingw itself.
959 * gdk_pixbuf.def: Add new entry points.
961 2000-09-26 Havoc Pennington <hp@redhat.com>
963 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
964 function here, instead of putting it in a private GTK+ file.
966 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
967 enum here for the known formats of inlined pixbufs.
968 Also, #define our file magic here.
970 2000-06-23 Havoc Pennington <hp@redhat.com>
972 * make-inline-pixbuf.c: Small program that creates C variable
973 declarations of inline pixbuf data. This can be read
974 by gdk_pixbuf_new_from_inline.
976 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
977 inline pixbuf data and create a pixbuf from it.
979 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
981 2000-09-07 Tor Lillqvist <tml@iki.fi>
983 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
986 2000-08-12 Tor Lillqvist <tml@iki.fi>
988 * gdk_pixbuf.def: Add missing entry point.
990 2000-08-10 Havoc Pennington <hp@redhat.com>
992 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
993 (s/pixbuf_/pixbufloader_)
995 2000-08-02 Tor Lillqvist <tml@iki.fi>
1001 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1003 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1004 one. Fix names of DLLs to have '-' instead of '_'.
1006 2000-07-31 Elliot Lee <sopwith@redhat.com>
1007 * io-wbmp.c: Some bug fixes - now tested to work.
1009 2000-07-27 Elliot Lee <sopwith@redhat.com>
1011 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1012 gdk_pixbuf_get_named_module() function to facilitate above change
1013 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1014 Implement loader for WBMP format.
1015 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1017 2000-07-23 Tor Lillqvist <tml@iki.fi>
1022 * pixops/makefile.mingw.in
1023 * pixbuf_*.def: New files.
1026 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1028 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1029 New function, to get the GTK+ installation directory from
1030 the Windows Registry, where the installation program
1031 for whatever software includes GTK+ has stored it.
1033 Used to avoid having hardcoding the directory where to look for
1034 loaders. This function is needed by gtk, too, so it should
1035 really be just in one place. Maybe a small static library
1036 one level up from here?
1038 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1039 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1040 Open file in binary mode. This *is* standard C. (No-op on Unix,
1043 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1045 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1046 mktemp() and open().
1047 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1049 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1050 pseudo-op. Conditionalise on __MINGW32__, but probably
1051 should conditionalise on Gas version instead? Or could we
1052 do without .type on all systems?
1054 * pixops/timescale.c: Use g_get_current_time()
1055 instead of gettimeofday().
1057 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1059 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1061 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1063 * gdk-pixbuf.c: Add <string.h> include.
1065 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1067 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1068 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1069 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1070 use g_object_new() instead of g_type_create_instance() which
1071 is a private function for fundamental type implementations.
1073 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1075 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1076 soname scheme for gdk-pixbuf.
1078 2000-06-21 Havoc Pennington <hp@pobox.com>
1080 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1081 (i.e. derivation is not allowed, and there are no virtual methods
1083 (gdk_pixbuf_preinit): Call g_type_init() here.
1084 (gdk_pixbuf_init): Add a user-friendly init function, for users
1085 of standalone gdk-pixbuf
1087 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1088 way GdkPixbufAnimation was done.
1090 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1091 gdk_pixbuf_finalize() from API, since these are broken and don't
1092 make sense with new GObject stuff.
1094 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1096 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1097 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1100 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1102 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1103 so I needed something to warm my thighs. Running plain infinite
1104 loops on your laptop to make it hot is not very much fun. A demo
1105 of the gdk-pixbuf scaling functions is way better, and looks
1108 * configure.in (AC_OUTPUT): Added the demo Makefile.
1110 * Makefile.am (SUBDIRS): Added the demo directory.
1112 2000-06-09 Larry Ewing <lewing@helixcode.com>
1114 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1115 setjmp for the png error handler. It seems setting the error
1116 handling functions does not avoid the jump, and so not calling
1117 setjmp was causing the incremental loader to jump into lala land.
1118 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1119 not sure this one is actually required but the docs say it must be
1120 set for every call to a png_* function.
1121 Also changed the comment to reflect the fact that setting the
1122 error handlers does _not_ avoid the longjmp.
1124 2000-06-06 Larry Ewing <lewing@helixcode.com>
1126 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1127 take frame offest into account when trying to calculate the
1128 animation bbox. Also set the width to the width not the height.
1129 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1130 calculate bbox because now we finally have all the offset
1131 information for each frame.
1133 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
1135 * configure.in: add some gtk parameters to the
1136 GDK_PIXBUF_LIB²S and GDK_PIXBUG_INCLUDEDIR vars. One more
1137 fight in my crusade for strange prefix compile...
1139 2000-05-30 Not Zed <NotZed@HelixCode.com>
1141 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
1142 Initialise the error handler exit routine to our own. Note this
1143 means that every function that accesses the jpeg lib on this
1144 object MUST do a setjmp.
1145 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
1146 lib for handling fatal error.
1147 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
1148 your applications dont quit if there's a jpeg error!
1150 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
1152 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
1153 from Frank de Lange <frank@unternet.org>.
1155 2000-05-09 Darin Adler <darin@eazel.com>
1157 * gdk-pixbuf/test-gdk-pixbuf.c:
1158 Fixed includes to get rid of accidental GNOME dependency.
1160 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
1161 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
1163 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
1165 * configure.in: Bumped version number to 0.8.0.
1167 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
1168 file was not being distributed.
1170 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
1172 2000-05-09 Darin Adler <darin@eazel.com>
1174 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
1175 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
1176 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
1177 formats to 32-bit formats to re-use the high bits of the color values
1178 so that white maps to full white.
1180 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
1182 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
1183 detailed information about the structure and algorithms
1184 of pixops so people can fix it instead of breaking it.
1186 2000-05-04 Darin Adler <darin@eazel.com>
1188 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
1189 (composite_pixel), (composite_line):
1190 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
1191 Now that Owen explained the algorithm, I think I implemented it
1192 right for the cases where the destination pixbuf is not opaque.
1193 The test does seem to confirm it.
1195 2000-05-04 Darin Adler <darin@eazel.com>
1197 * gdk-pixbuf/.cvsignore:
1198 * gdk-pixbuf/Makefile.am:
1199 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
1200 (load_pixel), (simple_composite_test_one),
1201 (simple_composite_test_one_type), (simple_composite_test), (main):
1202 Added some tests of composite to highlight problems in the old
1203 implementation. These tests run without any user interaction.
1204 Just do "make check".
1206 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
1207 (composite_pixel), (composite_line): Fix composite to do a textbook
1208 "A over B" composite. This was clearly the intent, and it was easy
1209 to fix the code to do it. (Note to those that read my earlier tries
1210 at a patch; this version fixes typos that were present in all
1211 my patch attempts. I checked the final version by adding more tests.)
1213 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
1215 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
1216 offset y coordinate accordining to render_y0.
1218 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
1221 2000-04-22 James Henstridge <james@daa.com.au>
1223 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
1224 package to the devel package. The only file installed in bin is
1225 gdk-pixbuf-config, which belongs in -devel. This should allow having
1226 multiple versions of the main gdk-pixbuf package installed.
1228 2000-04-17 Karl Eichwalder <ke@suse.de>
1230 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
1231 Reported by Jens Finke.
1233 2000-04-14 Tomasz K³opczko <kloczek@pld.org.pl>
1235 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
1236 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
1238 2000-04-13 James Henstridge <james@daa.com.au>
1240 * configure.in: when performing the configure check to see if
1241 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
1242 rather than the other way round. Also, call AC_MSG_RESULT in the
1243 even that dynamic modules were not supported.
1245 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
1247 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
1248 hook to the last unref operation.
1250 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
1251 function to set the last unref handler for a pixbuf.
1252 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
1253 It calls the pixbuf's destroy notification function and frees the
1254 GdkPixbuf structure itself.
1255 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
1258 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
1259 for the last unref handler and its user data.
1261 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
1262 g_new0() to allocate the pixbuf.
1264 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
1265 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
1266 was not specifying the `frame' argument.
1268 * gdk-pixbuf/gdk-pixbuf-animation.c
1269 (gdk_pixbuf_animation_get_width): Fixed docstring.
1270 (gdk_pixbuf_animation_get_height): Likewise.
1271 (gdk_pixbuf_animation_get_num_frames): Likewise.
1272 (gdk_pixbuf_animation_get_frames): Likewise.
1274 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
1277 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
1279 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
1281 * doc/tmpl/refcounting.sgml: Updated with the information about
1282 the last unref handler.
1284 * doc/tmpl/*.sgml: Markup tweaks.
1286 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
1287 update the libtool version number for libgnomecanvaspixbuf as
1289 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
1290 as well, or the old ones won't work with the new stuff. Also,
1291 renamed the modules as follows.
1293 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
1294 modules are called "libpixbufloader-<format>.so" instead of
1295 "libpixbuf-<format>.so". They needed renaming so that the new
1296 loaders won't overwrite the old ones; even with the versioning
1297 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
1300 2000-04-12 Paolo Molaro <lupus@debian.org>
1302 * .cvsignore, src/.cvsignore: shut up cvs.
1304 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
1306 Most of this patch is based on a patch by Havoc Pennington
1307 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
1308 remove the libart dependency.
1310 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
1311 (GdkColorspace): New enum that for now only contains
1313 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
1314 notification function.
1315 (GdkInterpType): New num with interpolation types.
1317 * *.[ch]: Replace the libart stuff with our own stuff.
1319 * pixops/*.[ch]: Likewise.

1338 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
1339 bits_per_sample argument; currently only 8 bits per sample are
1342 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
1344 (gdk_pixbuf_frame_get_x_offset): New accessor.
1345 (gdk_pixbuf_frame_get_y_offset): New accessor.
1346 (gdk_pixbuf_frame_get_delay_time): New accessor.
1347 (gdk_pixbuf_frame_get_action): New accessor.
1349 * gdk-pixbuf/gdk-pixbuf-render.c
1350 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
1351 mask rectangle for pixbufs without an alpha channel, set the
1352 *mask_return to NULL.
1354 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
1356 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
1358 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
1359 preconditions. Maybe we should also check for the colorspace,
1360 bits per pixel, and such.
1361 (gdk_pixbuf_composite): Likewise.
1362 (gdk_pixbuf_composite_color): Likewise.
1363 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
1364 cannot allocate the new pixbuf.
1365 (gdk_pixbuf_composite_color_simple): Likewise.
1367 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
1368 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
1371 * gdk-pixbuf/io-bmp.c: Fix includes.
1373 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
1378 * configure.in: Removed checks for libart.
1380 * gdk-pixbuf/Makefile.am: Removed references to libart.
1381 (noinst_HEADERS): Added gdk-pixbuf-private.h.
1383 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
1384 the version number of the libtool library to indicate that this
1385 definitely is not compatible with the old usage. I know you love
1388 * configure.in: Bumped version number to 0.7.0.
1392 * gdk-pixbuf-config.in (--libs): We no longer require libart.
1394 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
1396 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.

1400 * gdk-pixbuf/testanimation.c (main): add more info to the
1401 testanimation frames.

1411 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
1413 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
1414 is private information, and the art_pixbuf will go away soon.
1416 2000-03-31 Mark Crichton <crichton@gimp.org>
1418 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
1419 and gdk_pixbuf_get_artpixbuf accessor functions.
1421 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
1423 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
1424 gboolean instead of int.
1426 2000-03-29 Radek Doulik <rodo@helixcode.com>

1437 context->frame_done_func and context->anim_done_func to make
1438 progressive animation loading work
1440 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):

1456 precendence of >> and & which was keeping composite_color
1457 from working with non-gray images.
1459 2000-03-08 Jonathan Blandford <jrb@redhat.com>
1461 * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context.

1466 * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a
1467 mis-interpretation of the Microsoft documentation. Now
1468 it can load .BMP files that are not generated by The Gimp
1471 2000-03-01 Mark Crichton <crichton@gimp.org>
1473 * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
1474 fix the last auto* build bug (where we have libart, but no
1477 * gdk-pixbuf/Makefile.am: Same.
1479 2000-02-28 Matt Wilson <msw@redhat.com>
1481 * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,
1482 s/unsigned short/guint16/g, s/unsigned char/guint8/g
1484 2000-02-26 Federico Mena Quintero <federico@helixcode.com>
1486 * README: We don't require libgif/ungif nor libXpm.
1488 * NEWS: This was outdated, so updated it.
1490 2000-02-25 Federico Mena Quintero <federico@helixcode.com>
1492 * gdk-pixbuf.m4: Use the correct name for
1493 gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing

1506 * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml.
1508 * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment):
1509 Fixed typo in prototype name.
1511 * configure.in: Changed duplicated AC_MSG_CHECKING message to
1512 something more meaningful; now it is "checking whether dynamic

1888 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
1889 animation functions here.
1890 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
1891 animation if the loader does not support multiframe loading and
1892 the single-frame load returned NULL. Check that the filename is
1893 not NULL. Updated inline documentation.
1894 (gdk_pixbuf_animation_ref): New function.
1895 (gdk_pixbuf_animation_unref): New function.
1896 Removed gdk_pixbuf_animation_destroy() in favor of reference

1904 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
1907 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
1908 with a reference count of 1.
1910 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
1911 gdk-pixbuf-animation.c.
1913 * doc/tmpl/animation.sgml: Populated. It is still missing a
1914 description of the overlay modes.

1932 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
1933 set to NULL here (specifically context->animation) was not being
1934 set to NULL. use g_new0() to alloc the struct.
1936 1999-12-20 Jonathan Blandford <jrb@redhat.com>
1938 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
1939 correctly. Progressive loading needs some work, but that all
1940 needs doing from the gdk-pixbuf-loader end, not here.
1942 1999-12-17 Jonathan Blandford <jrb@redhat.com>
1944 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
1945 moved the file here. It seems natural to put this function here,
1946 as that's where the gdk_pixbuf_new_from_file function is, but it's
1947 still a little convoluted. The source files might be played with
1950 1999-12-14 Jonathan Blandford <jrb@redhat.com>
1952 * gdk-pixbuf/gdk-pixbuf-loader.c
1953 (gdk_pixbuf_loader_get_animation): Gets the animation from the

1964 * gdk-pixbuf/gnome-canvas-pixbuf.c
1965 (gnome_canvas_pixbuf_class_init): Renamed arguments to
1966 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for

1996 Filled in body of function.
1997 (rgbconvert): Added GdkColormap parameter, and to all conversion
1999 (convert_real_slow): New function - should convert ANY visual/data
2000 format properly, but it aint fast. Used as a fallback when an
2001 optimised routine wont match.
2002 (rgbconvert): Do very specific tests on the data format to verify
2003 properly if the optimised version will do, otherwise use the
2004 fallback function for all other data formats.
2006 * gdk-pixbuf/Makefile.am: Re-enabled building of
2007 textpixbuf-drawable.
2009 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
2010 gdk_pixbuf_get_from_drawable().

2022 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2023 checks and API definition. The body needs filling in and it needs
2024 to do the Right Thing(tm) for pixmaps plus the given colormap and
2025 windows and their own colormaps.
2027 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2028 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.

2065 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2066 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2067 want, send me a patch to do the conditional stuff properly.
2068 Otherwise, please read the GNOME Programming Guidelines,
2069 especially the "CVS policies" section.
2071 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>

2156 * src/gdk-pixbuf-data.c: Fix includes.
2158 * src/gdk-pixbuf-loader.c: #include <config.h>
2160 * src/gdk-pixbuf-loader.h: Use angle brackets for the gdk-pixbuf
2163 * src/Makefile.am: Commented out the gdk-pixbuf-drawable stuff,
2164 since it is not finished.
2166 * src/gdk-pixbuf.h: Removed unused transformation prototypes.
2168 * src/gdk-pixbuf-util.c: New file with utility and convenience
2169 functions for pixbufs.
2171 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-util.c.
2173 * doc/gdk-pixbuf-sections.txt: Added section for utility functions.
2175 * doc/Makefile.am (tmpl_sources): Added tmpl/util.sgml.
2177 * doc/gdk-pixbuf.sgml: Added the utilities section.
2179 * doc/tmpl/util.sgml: Documentation for the utility functions.
2181 1999-11-29 Owen Taylor <otaylor@redhat.com>
2183 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
2184 Keep the mask around until after we draw ... since
2185 the GC changes aren't flushed to the X server until we
2186 draw, destroying it before that may result in BadPixmap
2189 1999-11-30 Havoc Pennington <hp@pobox.com>
2191 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
2193 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
2195 1999-11-29 Federico Mena Quintero <federico@redhat.com>
2197 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
2198 should be made conditional, not blindly commented out.
2200 1999-11-29 Jonathan Blandford <jrb@redhat.com>
2202 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
2203 handle .ico files. Cool.
2205 1999-11-24 Jonathan Blandford <jrb@redhat.com>
2207 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
2210 1999-11-24 James Henstridge <james@daa.com.au>
2212 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
2213 top builddir rather than src. This still builds fine, and does not
2214 get gtk-doc into an infinite loop when trying to find all the source
2217 1999-11-23 Jonathan Blandford <jrb@redhat.com>
2219 * Removed #PRAGMA } from headers. Also, make compile if you don't
2220 have it installed, already.
2222 1999-11-22 Federico Mena Quintero <federico@redhat.com>
2224 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
2225 temporary buffer to the size of the interesction of the bounding
2226 box and the expose area, not the whole expose area. This speeds
2229 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
2230 not paint black on the mask, since we already cleared it in a
2231 single gdk_draw_rectangle() operation.
2233 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
2235 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
2237 1999-11-22 Havoc Pennington <hp@pobox.com>
2239 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
2240 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
2241 dependencies to LIBADD variables for loadable modules. Necessary
2242 for a Java dynamic loading thing to be able to figure it out.
2244 1999-11-22 Havoc Pennington <hp@pobox.com>
2246 * src/io-png.c (image_load_increment): Call the update_area
2247 callback depending on the number of rows loaded in this increment.
2249 * src/testpixbuf.c (main): slow down the progressive load demo
2251 1999-11-16 Havoc Pennington <hp@pobox.com>
2253 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
2255 1999-11-22 Jonathan Blandford <jrb@redhat.com>
2257 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
2258 for srcdir != buildir != . Beats me why; I can't figure it out.
2259 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
2261 1999-11-21 Jonathan Blandford <jrb@redhat.com>
2263 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
2264 <arjan@fenrus.demon.nl>
2266 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2268 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
2269 Rework/reorder of the code. Each case has been separated into
2270 another function; its big but it should be quick.
2271 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
2272 opaque alpha information. Not all depths/formats have been
2273 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
2275 1999-11-17 Larry Ewing <lewing@gimp.org>
2277 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
2278 implement the bounds method correctly.
2279 (compute_viewport_affine): compute the affine need to fit the
2280 image within the viewport given by the args.
2281 (compute_render_affine): call compute_viewport_affine.
2283 1999-11-16 Havoc Pennington <hp@pobox.com>
2285 * src/gdk-pixbuf-drawable.h: Use includes from the current
2286 directory, not the system directory.
2288 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
2290 * src/testpixbuf-drawable.c: use includes from the current directory
2291 rather then from the system include directory as gdk-pixbuf
2292 includes are not yet installed when this is compiled.
2294 1999-11-13 Cody Russell <bratsche@dfw.net>
2295 * src/testpixbuf-drawable.c: Added a test program for drawable
2298 * src/Makefile.am: Build testpixbuf-drawable.
2300 1999-11-12 Cody Russell <bratsche@dfw.net>
2302 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.
2304 1999-11-10 Federico Mena Quintero <federico@redhat.com>
2306 * doc/tmpl/gdk-pixbuf-loader.sgml: Populated.
2308 * doc/gdk-pixbuf.signals: Put in the real names of signal
2311 * src/gdk-pixbuf-loader.c: Improved documentation comments.
2313 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2315 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
2318 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
2319 correctly. Patch from Arjan to do so.
2321 1999-11-10 Michael Fulbright <drmike@redhat.com>
2323 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
2326 * src/testpixbuf.c: Added final queued draw when done loading image.
2328 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2330 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
2333 1999-11-10 Federico Mena Quintero <federico@redhat.com>
2335 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
2338 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2340 * src/io-png.c: Fixed some incompatible pointer initializations.
2342 * src/io-jpeg.c (image_load_increment): Remove unused variable.
2344 1999-11-09 Michael Fulbright <drmike@redhat.com>
2346 * src/testpixbuf.c: Fixed it to use timeout to read from file
2347 for progressive loading. Set TBF_KBPS=n, where n is the number of
2348 kilobytes/second to simulate in downloading. n has to be an integer.
2350 * src/io-jpeg.c: Slight cosmetic cleanup.
2352 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
2353 PBM loading has a similar problem and will address tomorrow.
2355 1999-11-09 Havoc Pennington <hp@pobox.com>
2357 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
2358 gdk-pixbuf-drawable stuff.
2360 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2362 * configure.in: Bumped version number to 0.4.
2364 1999-11-09 Michael Fulbright <drmike@redhat.com>
2366 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
2367 all types of PNM files now.
2369 * src/io-jpeg.c (image_load_increment): Figured out problem with
2370 loading Progressive JPEG's progressively (say that 10 times fast).
2371 Currently for Progressive JPEG's the entire image is loaded before
2372 it is displayed. libjpeg supports a fancier mechanism which I may
2375 With these changes all JPEG formats appear to load properly for me.
2377 1999-11-08 Jonathan Blandford <jrb@redhat.com>
2379 * src/io-ras.c (image_load_increment): Final patch from Arjan.
2380 Seems to do progressive loading.
2382 1999-11-08 Michael Fulbright <drmike@redhat.com>
2384 * src/io-pnm.c image_load (): Fixed so we do not create a separate
2385 pixel buffer when reading in image - we reuse the pixel data in
2386 the GdkPixbuf structure instead.
2388 1999-11-08 Michael Fulbright <drmike@redhat.com>
2390 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
2391 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
2392 I can't seem to find a utility to convert into this format.
2393 Next is to add progressive loading support for the PNM format.
2395 1999-11-07 Federico Mena Quintero <federico@redhat.com>
2397 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
2398 of the width, height, x, and y setting and pixels arguments.
2400 1999-11-05 Jonathan Blandford <jrb@redhat.com>
2402 * src/io-ras.c (image_load): third patch. Now it seems to load.
2404 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
2405 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
2407 * src/io-ras.c (image_load): new file from Arjan van de Ven
2408 <arjan@fenrus.demon.nl> to begin the ras loader.
2410 1999-11-05 Federico Mena Quintero <federico@redhat.com>
2412 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
2413 for internal use only.
2415 * doc/gdk-pixbuf.sgml: Likewise.
2417 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
2419 1999-11-05 Michael Fulbright <drmike@redhat.com>
2421 * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
2422 files from a file. Next step is support for ASCII files, and
2423 then incremental loading.
2425 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2427 * Makefile.am: Added doc to SUBDIRS.
2429 1999-11-04 Michael Fulbright <drmike@redhat.com>
2431 * src/io-jpeg.c: Prettied up code slightly.
2432 * src/io-pnm.c: Start of pnm loader (from file and progressively).
2433 Doesn't do much yet (will finish tomorrow).
2434 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
2436 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2438 * doc/tmpl/rendering.sgml: Populated.
2440 * doc/Makefile.am: Added the template files.
2442 1999-11-04 Havoc Pennington <hp@pobox.com>
2444 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
2445 docs, explain what a dither offset is for.
2446 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
2447 this function vs. gdk_pixbuf_render_to_drawable().
2449 1999-11-04 Havoc Pennington <hp@pobox.com>
2451 * configure.in: Use libart-config correctly; find gnome-config
2452 separately. Fix GNOME_LIBS to be correct in "no gnome installed
2455 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
2458 Patch untested in the inside-gnome-libs case, I need to commit
2459 then check out to the gnome-libs I'm using.
2461 1999-11-04 Michael Fulbright <drmike@redhat.com>
2463 * src/io-jpeg.c (image_begin_load): Add update_func callback.
2464 * src/io-jpeg.c (image_load_increment): Call updated callback when
2465 new graphic data decoded.
2467 1999-11-04 Jonathan Blandford <jrb@redhat.com>
2469 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_update): handle the
2471 * src/io-png.c (image_begin_load): add a update_func callback.
2472 * src/io-gif.c (image_begin_load): add a update_func callback.
2473 (gif_get_lzw): added the update_func ability
2475 * src/io-tiff.c (image_begin_load): add a update_func callback.
2477 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2479 * doc/tmpl/gdk-pixbuf.sgml: Populated.
2481 * doc/tmpl/refcounting.sgml: Populated.
2483 * doc/tmpl/file-loading.sgml: Populated.
2485 * src/gdk-pixbuf.c: Added documentation comments.
2487 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Added
2488 documentation comments.
2490 * doc/: Finished integrating the documentation framework.
2492 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2494 * configure.in: Removed libgif stuff now that we do not depend on it.
2495 Added the necessary cruft for gtk-doc.
2497 * src/Makefile.am: Unconditionally build the GIF loader.
2499 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2501 * src/io-gif.c (gif_read): renamed ReadOK to gif_read.
2502 Added a lot of comments to the file.
2504 * src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on
2507 1999-11-03 Michael Fulbright <drmike@redhat.com>
2509 * src/io-jpeg.c (image_load_increment): Further removal of
2510 bugginess in local buffering code. Handles grayscale jpegs
2513 * src/io-jpeg.c (image_load_stop): Was freeing local context
2514 for jpeg library before calling jpeg_decompres_finish ().
2516 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2518 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
2520 (gif_get_lzw): set the transparency to the right val.
2522 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2524 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
2525 Initiailize the x and y fields.
2526 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
2527 (PixbufPrivate): Renamed need_size_update to need_xform_update.
2528 (recompute_bounding_box): Do not use temporary values.
2530 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2532 * src/io-gif.c (set_gif_lzw_clear_code): new state. Fixes
2535 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): remove
2536 unneeded x,y,h,w vars.
2538 1999-11-03 Larry Ewing <lewing@gimp.org>
2540 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
2541 render_affine calculation for x,y offsets.
2542 (gnome_canvas_pixbuf_set_arg): add x,y args.
2543 (gnome_canvas_pixbuf_get_arg): add x,y args.
2544 (recompute_bounding_box): simply code using ArtDrect and the
2545 render_affine. Removed compute_xform_vectors as it was no longer
2548 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2550 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
2551 doofus. Return a distance, not a boolean, for opaque images.
2553 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
2554 rounding of bounding box coordinates.
2555 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
2556 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
2558 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2560 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
2562 1999-11-03 Michael Fulbright <drmike@redhat.com>
2564 * src/io-jpg.c (image_load_increment): Fixed code which moved
2565 buffer around as new data comes in to work properly. JPEG progressive
2566 loading should be working now except for grayscale JPEG's, which I
2567 will look into next.
2569 1999-11-03 <sopwith@redhat.com>
2570 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
2571 Also put dot printing back in.
2573 1999-11-03 <jrb@redhat.com>
2575 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
2578 1999-11-02 Cody Russell <bratsche@dfw.net>
2579 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
2580 if part of the requested image is offscreen, rather than clipping
2583 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2585 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
2586 for interlacing and progressive loading.
2588 1999-11-02 Cody Russell <bratsche@dfw.net>
2589 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
2590 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
2592 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2594 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
2595 It's a little slow though. )-:
2597 1999-11-02 Elliot Lee <sopwith@redhat.com>
2598 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
2599 write/load_increment operations const-correct.
2601 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2603 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
2604 Implemented the ::point() method. We do a simple containment test
2605 instead of a full distance calculation since the canvas is going
2606 to change to that scheme, anyways.
2608 1999-11-02 Elliot Lee <sopwith@redhat.com>
2610 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
2611 that are read from the input file.
2613 1999-11-02 Larry Ewing <lewing@gimp.org>
2615 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
2617 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
2620 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2622 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
2623 affine computation code from ::draw() to here, since it is needed
2624 by ::point() as well.
2626 1999-11-02 Elliot Lee <sopwith@redhat.com>
2628 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
2629 three functions, and eliminate duplication of code from write()
2630 and close(). Also fix bug where the 128-byte header was being
2633 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2634 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
2635 bounding box computation.
2637 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2639 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
2640 Drawing affines seem to work. Bounding box is fubared. ::point()
2641 is not implemented. This is a work in progress.
2643 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
2646 * configure.in: Sigh. We need to link in libgnomeui for the
2647 canvas stuff. This mess will disappear when gdk-pixbuf gets
2648 folded into gnome-libs.
2650 1999-10-30 Jonathan Blandford <jrb@redhat.com>
2652 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
2653 the right size, at a minimum, even if the image is squished and
2655 (ReadImage): lets get the offset right. This will let transparent
2658 1999-10-29 Michael Fulbright <drmike@redhat.com>
2660 * src/io-jpeg.c: image_load_increment(): Fixed bug when
2661 image width was not a multiple of 4 - always use the
2662 gdk_pixbuf rowstride to increment pointers!
2664 1999-10-29 Michael Fulbright <drmike@redhat.com>
2666 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
2667 Currently does not handle either progressive jpeg files (jpeg
2668 files with multiple scans at different quality settings), but
2669 I plan on adding this support soon. These are fairly rare in
2670 my experience, so it shouldn't slow people down too much.
2671 Grayscale jpegs also don't work but that should be easy to fix.
2673 1999-10-29 Michael Fulbright <drmike@redhat.com>
2675 * src/testpixbuf.c: Added title to windows so you can identify
2676 progressive and file windows.
2678 1999-10-29 Michael Fulbright <drmike@redhat.com>
2680 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
2681 load the image handler when we determine the image type.
2683 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
2684 previously static function load_image_handler () to
2685 a public function gdk_pixbuf_load_module (). It is needed in
2686 gdk-pixbuf-loader.c to load image handler modules. This function
2687 is different from gdk_pixbuf_get_module (), which only returns
2688 a reference to the required handler, because it actually loads
2689 the handler into memory. Both actions should possibly be combined
2690 in a convenience function since one w/o the other doesn't seem to
2693 1999-10-28 Jonathan Blandford <jrb@redhat.com>
2695 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
2698 1999-10-28 Federico Mena Quintero <federico@redhat.com>
2700 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
2701 function to render a portion of a pixbuf to a drawable. Ignores
2702 alpha information and takes in a GC.
2703 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
2704 portion of a pixbuf to a drawable. It automatically creates a GC
2705 and a clipping mask for alpha pixbufs.

2895 GdkPixBuf to GdkPixbuf, for consistency with the function names
2896 (and it is also easier to type) :-)
2898 1999-10-18 Havoc Pennington <hp@pobox.com>
2900 * configure.in: Use AM_PATH_GLIB instead of glib-config directly

2912 comment out testpixbuf for now
2914 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2916 * configure.in: Use $GTK_LIBS as the extra libs when checking for
2917 libgif/libungif, as they need the X libraries. Fixes bug #2472.
2919 1999-10-10 Cody Russell <bratsche@dfw.net>
2920 * src/gdk-pixbuf-drawable.c: core function now determines whether
2921 the requested geometry is on screen or not, and if some is not
2922 then the request is clamped to geometry that is on the screen.
2924 Changed 'pixbuf' to 'art_pixbuf' in core function.
2926 1999-10-08 Michael Fulbright <drmike@redhat.com>
2928 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

2934 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
2935 them, but I wrote them).
2937 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
2940 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
2941 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

3022 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3023 require extra libraries if we actually have those libraries.
3025 1999-07-23 Richard Hestilow <hestgray@ionet.net>

3042 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3043 error cases but one or two in the common case. There are probably
3044 a few small ones left.
3046 1999-07-18 Mark Crichton <crichton@gimp.org>
3048 * configure.in: removed version.h.
3050 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability

3066 (config_func): bring this up to date with the new pixbuf_scale
3069 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3070 loading code so that poeple can diagnose problems better.
3072 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3073 no longer allocates a new pixbuf, which make things nicer for the
3074 rest of the code. Unfortunately there is still a problem with
3075 scaling rgba images.
3077 1999-07-16 Mark Crichton <crichton@gimp.org>
3079 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3080 calls gdk_pixbuf_scale. However, something is not working.
3081 N.B.: current pixmap is now stored in user_data with a key of
