736 * gdk-pixbuf-io.h (ModuleSizeFunc): New.
737 (_GdkPixbufModule): Prepend a ModuleSizeFunc to the

739 * gdk-pixbuf-loader.c (struct GdkPixbufLoaderPrivate): Add
740 fields width, height, size_fixed, need_scale.
741 (gdk_pixbuf_loader_class_init): Add size_prepared signal.
742 (gdk_pixbuf_loader_set_size): New function.
743 (gdk_pixbuf_loader_size_func): ModuleSizeFunc which gets
744 passed to the module, emits size_prepared.
745 (gdk_pixbuf_loader_prepare): Call gdk_pixbuf_loader_size_func
746 if necessary, only emit area_prepared if no separate scaling
748 (gdk_pixbuf_loader_update): Only emit area_updated if no
749 separate scaling is required.
750 (gdk_pixbuf_loader_load_module): Add size_func as first argument.
751 (gdk_pixbuf_loader_close): If necessary scale the image
752 to the desired size and emit area_prepared and area_updated.

754 size_prepared signal.
755 (gdk_pixbuf_loader_set_size) New API.
756 * gdk-pixbuf-marshal.list: Add VOID:INT,INT.
757 * io-jpeg.c: User cinfo->output_width/height instead of
758 cinfo->image_width/height throughout when adressing the pixbuf.
759 (gdk_pixbuf__jpeg_image_load_increment): Call size_func, and
760 find the nearest possible output size which libjpeg can produce
761 that is still larger than the desired size.
763 2002-07-06 Matthias Clasen <maclas@gmx.de>
765 * io-tiff.c (tiff_set_error): Handle global_error == NULL
767 (tiff_image_parse): Don't trust TIFFRGBAImageBegin to set

772 2002-07-02 Matthias Clasen <maclas@gmx.de>
774 Miscellaneous bmp loader fixes (#85448, #86286, #86287):
776 * io-bmp.c (grow_buffer): New function to avoid crashes
777 on unchecked reallocs.
778 (DecodeHeader, DecodeColormap, decode_bitmasks,
779 DoCompressed): Use grow_buffer instead of g_realloc
780 throughout. Change signatures where necessary to pass the
782 (OneLine16): Fix loading of 16bpp BI_RGB bmps.
783 (DoCompressed): Rewritten to properly support BI_RLE4 and
786 Support for compressed ras images (#84994):
788 * io-ras.c (RAS2State): Error on unsupported ras variations.
789 (OneLine8): Fix colormap indexing.
790 (OneLine): Call updated_func with proper region.
791 (DoCompressed): New function, handles compressed ras data.
792 (gdk_pixbuf__ras_image_load_increment): Handle compressed ras
795 Better colorspace support for the jpeg loader (#61211):
797 * io-jpeg.c (convert_cmyk_to_rgb): New function.
798 (gdk_pixbuf__jpeg_image_load,
799 gdk_pixbuf__jpeg_image_load_increment): Allocate a pixbuf with
800 alpha for 4-channel jpegs and call convert_cmyk_to_rgb for these.
802 All of this needs to be merged to GNOME 1.4 gdk-pixbuf.
804 2002-06-28 Sven Neumann <sven@gimp.org>
806 * gdk-pixbuf-csource.c (print_blurb): converted a Tab to spaces.
808 Thu Jun 13 18:11:11 2002 Owen Taylor <otaylor@redhat.com>
810 * pixops/pixops.c: Fix problem where when no alpha was
811 involved, we scaled rather than composited, but then
812 went ahead and composited anyways. (#76958, Patch
813 from Matthias Clasen). Needs to be merged to GNOME
816 2002-06-13 Matthias Clasen <maclas@gmx.de>
818 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
819 incrementally display incrementally loaded progressive jpegs.
821 2002-06-07 Federico Mena Quintero <federico@ximian.com>
824 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
825 starting at a specific memory location. We do this instead of
826 GINT32_FROM_LE() as the latter is simply dereferences a cast,
827 which doesn't work on platforms with alignment requirements.
830 2002-06-01 Matthias Clasen <maclas@gmx.de>
832 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting
833 with a C comment - those seem to be not uncommon, e.g. the Gimp
834 produces them. (#82706)
836 * io-xbm.c (read_bitmap_file_data): Don't leak memory on certain
838 (gdk_pixbuf__xbm_image_load_real): Don't leak memory on valid inputs.
840 2002-05-22 Tor Lillqvist <tml@iki.fi>
842 * gdk-pixbuf-io.c (get_libdir): Use GTK_BINARY_VERSION (and not
843 GTK_VERSION) in the path to the loaders on Win32, too.
845 * Makefile.am: Pass GTK_BINARY_VERSION.
847 2002-05-22 Federico Mena Quintero <federico@ximian.com>
849 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
850 account!!! Fixes #82515.
852 [This bug is not present in the GNOME 1.4 branch as its XPM loader
853 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
854 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
856 [IMPORTANT: The comment above is to make my life easier when
857 merging stuff across branches. If you make changes to gdk-pixbuf
858 in either branch, please include a comment in the ChangeLog that
859 indicates whether this should be merged into the other branch.
862 2002-05-18 Matthias Clasen <maclas@gmx.de>

877 2002-05-07 Michael Natterer <mitch@gimp.org>
879 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
880 conditionally like the dynamic ones so --without-lib<foo> is
881 honored when building with --disable-modules. (#66867)
883 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
885 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to
887 * test-loaders.c, test-images.h: remove
889 2002-04-24 Matthias Clasen <maclas@gmx.de>
891 * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
892 restriction from the description of png tEXt parameters.
894 * io-png.c (png_text_to_pixbuf_option):
895 (gdk_pixbuf__png_image_save): If libpng supports it,
896 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)
898 2002-04-11 Matthias Clasen <maclas@gmx.de>
900 More fixes for #77807:
902 * io-tga.c (get_contiguous_pixbuf): Helper function to create
903 a pixbuf with a contiguous pixel array while being careful about
906 * io-tga.c (fill_in_context, get_image_pseudocolor,
907 get_image_truecolor, get_image_grayscale): Use
908 get_contiguous_pixbuf instead of manually allocating image
911 * io-xpm.c (pixbuf_create_from_xpm):
912 * io-pnm.c (gdk_pixbuf__pnm_image_load):
913 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
914 instead of manually allocating image storage.
916 2002-04-09 Matthias Clasen <maclas@gmx.de>
918 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
919 priv->image_module->module_name instead of image_type which may
922 2002-04-06 Matthias Clasen <maclas@gmx.de>
924 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
925 gdk_pixbuf_new instead of manually allocating image storage. This
926 gives us a good rowstride and overflow checks. (#77807)
928 2002-04-05 Matthias Clasen <maclas@gmx.de>
930 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
931 the image by using a TIFFRGBAImage{Begin,Get,End} with suitable
932 put functions instead of TIFFRGBAImage. And check image dimensions

937 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_get_type): Fix a doc typo.
939 2002-03-29 Matthias Clasen <maclas@gmx.de>
941 * io-png.c (png_simple_error_callback): libpng error handlers must
942 not return to their callers, thus longjmp out. This prevents
943 annoying stderr output from the default error handler.
945 2002-03-27 Matthias Clasen <maclas@gmx.de>
947 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
949 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
950 end_info. Also call png_read_end to check proper ending of the png
951 file and catch text chunks after the image data.
953 2002-03-27 Matthias Clasen <maclas@gmx.de>
955 * io-png.c (gdk_pixbuf__png_image_load,
956 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
957 instead of system malloc.
959 2002-03-26 Matthias Clasen <maclas@gmx.de>
961 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
963 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
964 context->buf on error.
966 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
967 stop_load even for short images to prevent memleaks.
969 2002-03-25 Matthias Clasen <maclas@gmx.de>
971 * io-png.c (setup_png_transformations): Changed signature to
972 return success and set a GError parameter, adjusted all callers.
973 Also work around a possible FPE in libpng and always check that
974 the new info is sane.
976 2002-03-23 Matthias Clasen <maclas@gmx.de>
978 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
979 context->updated_func is NULL during a nonincremental load.
980 (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.
982 2002-03-18 Matthias Clasen <maclas@gmx.de>
984 * io-tga.c: Fix assumptions on rowstride by manually allocating a
985 contiguous pixel buffer. Catch buffer overruns in RLE-modi.
986 Support grayscale + alpha (which can be written, but not read (!)
989 2002-03-15 Matthias Clasen <maclas@gmx.de>
991 * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.
993 2002-03-13 Matthias Clasen <maclas@gmx.de>
995 * test-images.h: Add valid_ras_test and invalid_bmp_1.
997 * test-loaders.c (main): Add random tests for ras and pnm and an
998 invalid bmp which was a crasher until my 2002-03-12 commit.
1000 * io-pnm.c (gdk_pixbuf__pnm_image_load_increment): Don't unref the
1003 * io-ras.c: Handle some errors.
1005 2002-03-12 Sven Neumann <sven@gimp.org>
1007 * gdk-pixbuf.c (gdk_pixbuf_fill): use sequential writes instead of
1008 calling memcpy(). Simpler and potentially faster. (#70332)
1010 2002-03-12 Matthias Clasen <maclas@gmx.de>
1012 * io-bmp.c (DecodeHeader): Replace a g_assert_not_reached ()
1013 which could actually be reached by a proper error status return.
1015 2002-03-05 Matthias Clasen <maclas@gmx.de>
1017 * test-loaders.c, test-images.h: More random tests.
1019 * io-bmp.c (DecodeHeader): Fail gracefully on OOM here.
1021 Tue Mar 5 10:39:03 2002 Owen Taylor <otaylor@redhat.com>
1023 * Makefile.am (loaderdir): Put the modules into the
1024 GTK_BINARY_VERSION directory for consistency with
1025 immodules and theme engines.
1027 Sat Mar 2 22:11:10 2002 Owen Taylor <otaylor@redhat.com>
1029 * gdk-pixbuf-io.c (_gdk_pixbuf_load_module): If we
1030 can't load the module using the g_module_build_path()
1031 filename, try loading it as a .la file.
1033 * test-loaders.c: Look for modules in current directory
1034 rather than .libs, so we find the right .la files.
1036 * test-loaders.c: Back out some accidental commits.
1038 Sat Mar 2 21:28:03 2002 Owen Taylor <otaylor@redhat.com>
1040 * gdk-pixbuf.c (gdk_pixbuf_new): Bullet-proof against integer

1054 2002-02-28 Matthias Clasen <maclas@gmx.de>
1056 * pixops/pixops.c (tile_make_weights): Move the call to
1057 correct_total() to the right spot. (#72732)
1059 Wed Feb 27 18:33:04 2002 Owen Taylor <otaylor@redhat.com>
1061 * gdk-pixdata.c (gdk_pixdata_to_csource): Use {} not
1062 () to group around string assigned to char[]. (#72767,
1065 2002-02-21 Havoc Pennington <hp@pobox.com>
1067 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove

1072 * pixops/pixops.c (correct_total): New function to make sure
1073 that the weights sum up to the correct total without introducing
1075 (tile_make_weights, bilinear_make_fast_weights,
1076 bilinear_make_weights): Use correct_total.

1359 * gdk-pixbuf.h, gdk-pixdata.c: Rename gdk_pixbuf_new_from_stream()
1360 back to gdk_pixbuf_new_from_inline(). Rework docs to try

1403 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
1404 works in some on-demand way, so the fseek
1405 gdk_pixbuf_new_from_file() doesn't work here since we are using
1406 the raw file descriptor. So, we call lseek() on the fileno(f)
1407 before using it. (#60840).
1409 2001-09-20 James Henstridge <james@daa.com.au>
1411 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,
1412 so that flags types are registered as flags rather than enums (not

1417 * Makefile.am (gdk_pixbuf_headers): Don't include
1418 gkd-pixbuf-features.h here since is in builddir

1422 automake-1.5 doesn't like it.
1424 * Makefile.am: Fix srcdir != builddir for gdk-pixbuf-enum-types.c.
1426 * Makefile.am: The whitespace strikes back.
1428 2001-09-17 Matt Wilson <msw@redhat.com>
1430 * Makefile.am (libpixbufloader_xbm_la_LDFLAGS): removed duplicate
1431 LDFLAGS definition, use the -avoid-version one.

1461 * io-xpm.c (parse_color): detect very long color strings
1463 All of the above from Matthias Clasen <matthiasc@poet.de>,
1464 the remaining from Soeren Sandmann <sandmann@daimi.au.dk>.
1466 * test-images.h: add tests:
1467 - four valid ppm's, eight invalid (matthiasc@poet.de)
1468 - one invalid xpm (matthiasc@poet.de)
1469 - one valid tga, one invalid (sandmann@daimi.au.dk)
1470 - one invalid tiff (sandmann@daimi.au.dk
1472 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
1474 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
1475 fail - detect it when it happens
1477 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
1480 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
1483 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
1485 * Makefile.am: don't used BUILT_SOURCES to build marshal
1486 files, as in conjunction with stamp files, this can
1487 lead to endless rebuilding loops.
1489 Tue Sep 4 00:22:07 2001 Owen Taylor <otaylor@redhat.com>
1491 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1

1530 2001-08-19 Sven Neumann <sven@gimp.org>
1532 * pixops/pixops.c: applied some simple but effective optimizations
1533 to pixops_composite_nearest() and pixops_composite_color_nearest().
1535 2001-08-07 Sven Neumann <sven@gimp.org>
1537 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
1538 function, so that's what I did.
1540 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
1542 * gdk-pixdata.c: Fix a typo.

1598 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
1600 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
1601 instead from gdk_pixbuf_new_from_inline().
1603 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
1604 installed API for applications that need to serialize/deserialize
1605 on their own (gimp, BEAST).
1607 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
1608 program that can dump images in CSource format and Pixbuf
1609 stream format. supports RLE encoding, MACRO formatting etc...
1612 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
1614 * Makefile.am: Actually update timestamps, so rules don't
1617 2001-06-11 Havoc Pennington <hp@redhat.com>
1619 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
1620 already includes top_builddir
1622 2001-06-08 Havoc Pennington <hp@redhat.com>
1624 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
1625 bogus g_return_if_fail
1627 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
1628 likely timeout resolution, set it to an arbitrarily-chosen short
1630 Fixes bug #55953 from warmenhoven@yahoo.com
1632 2001-06-07 Havoc Pennington <hp@redhat.com>
1634 * Makefile.am: use Owen's new way of doing stampfiles/generated
1637 2001-06-07 Havoc Pennington <hp@redhat.com>
1639 * Makefile.am (gdk-pixbuf-marshal.c): fix up the glib-genmarshal path
1641 2001-06-05 Havoc Pennington <hp@redhat.com>
1643 * test-loaders.c (main): use putenv not setenv, reported by
1646 2001-05-08 Havoc Pennington <hp@redhat.com>
1648 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
1649 and fix behavior to still subst color if the original image
1652 2001-06-04 Havoc Pennington <hp@redhat.com>
1654 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
1657 2001-06-01 Havoc Pennington <hp@redhat.com>
1659 Apply patch from sandmann@daimi.au.dk, with some tweaks.
1660 Makes things a bit more robust, and adds test-loaders.c
1661 which is good for finding further robustness bugs to fix.
1663 * io-tiff.c: Try to work around libtiff suckiness a bit;
1664 put a giant thread lock on the whole loader,
1665 paranoically check both whether error handlers were called and
1666 also whether functions return false. Handle case where width or
1667 height is 0. Various cleanups.
1669 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
1671 (png_error_callback): apparently libpng expects you to longjmp out
1674 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
1675 (lzw_read_byte): change "Mail jrb if this fails" g_warning
1677 (gif_get_lzw): check for out-of-memory
1678 (gif_prepare_lzw): catch/report an error
1679 (new_context): use try_malloc, since GifContext is nearly 70K
1680 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
1681 so we don't crash later.
1683 * Makefile.am: Add test-loaders
1685 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
1688 2001-05-29 Darin Adler <darin@eazel.com>
1690 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
1692 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
1694 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
1695 fix up bmp decoder to:
1696 - adds 16 bpp bmp support (bug #53884)
1697 - adds OS/2 1.x format bmp support (bug #54964)
1698 - adds 4 bpp RLE compressed bmp support
1699 - adds 1 bpp colormap support
1700 - fixes negative height (top down) bmp support
1702 2001-05-25 Hans Breuer <hans@breuer.org>
1704 * gdk_pixbuf.def : reflect Havoc's recent api change
1706 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
1708 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
1709 excess $(GLIB_LIBS).
1711 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
1713 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
1715 2001-05-04 Havoc Pennington <hp@redhat.com>
1717 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
1718 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
1721 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
1722 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
1723 confusion of using "src" instead of "p".
1724 (pixops_composite_color_nearest): Use a more accurate (and
1725 correct, to begin with) compositing method. This cures checks
1726 showing through on images with no alpha.
1728 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
1731 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
1733 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
1734 area_updated signal to use signed ints. Removed animation-related
1737 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
1740 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
1741 all the pesky details. Remove old frame-based API. Make
1742 GdkPixbufAnimation an abstract base class, derived by the loaders.
1744 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
1746 * Makefile.am (LDADDS): Add $(MATH_LIB).
1748 2001-04-18 Havoc Pennington <hp@redhat.com>
1750 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
1753 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
1755 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
1756 so we don't try to get <gtk/gtkobject.h> from standard search
1759 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
1760 add gdk-pixbuf-marshal.list to EXTRA_DIST.
1761 take gdk-pixbuf-marshal.h out of _la sources.
1763 2001-03-19 Tor Lillqvist <tml@iki.fi>
1765 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
1767 * gdk_pixbuf.def: Update.
1769 * pixbufloader_*.def: Just export the fill_vtable functions now.
1771 2001-03-18 Mike Kestner <mkestner@ameritech.net>
1773 * make-inline-pixbuf.c (main): Added logic to remove output when
1776 2001-03-14 Havoc Pennington <hp@redhat.com>
1778 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
1779 from gdk-pixbuf-marshal.h, fixes parallel makes.
1781 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
1783 * test-gdk-pixbuf.c: fixed includes.
1785 2001-02-18 Havoc Pennington <hp@pobox.com>
1787 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
1788 (gdk_pixbuf_get_named_module): prepend underscore
1789 (gdk_pixbuf_get_module): prepend underscore
1791 2001-02-19 Havoc Pennington <hp@redhat.com>
1793 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
1795 2001-02-17 Havoc Pennington <hp@pobox.com>
1797 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
1799 2001-02-07 Alexander Larsson <alexl@redhat.com>
1801 * io-xpm.c (free_buffer):
1802 Use g_free, since the buffer is allocated with g_try_alloc().
1804 2001-02-06 Christophe Merlet <redfox@eikonex.org>
1806 * gdk-pixbuf-data.c: Fixes a minor typo.
1808 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
1810 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
1811 we finally need the gobject->gruntime rename.
1813 * *.c: scratched calls to g_type_init(), there's simply no point in
1814 doing that, use gtk_init().
1816 2001-02-01 Havoc Pennington <hp@pobox.com>
1818 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
1819 in struct to "priv" for C++
1821 2001-01-31 Havoc Pennington <hp@pobox.com>
1823 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
1825 2001-01-26 Havoc Pennington <hp@redhat.com>
1827 * gdk-pixbuf-io.c (mname): fix included modules case.
1829 2001-01-22 Havoc Pennington <hp@redhat.com>
1831 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
1832 from gdk_pixbuf_load_module
1834 2001-01-22 Havoc Pennington <hp@redhat.com>
1836 * Makefile.am: Add built marshaller files to support
1837 GdkPixbufLoader signals
1839 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
1840 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
1841 module location, rather than acting as a fallback, because we are
1842 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
1844 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
1846 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
1847 from gtk, and add error to close(), because stop_load may do
1848 parsing of the image.
1850 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
1852 * io-*.c: make individual operations static, and add fill_vtable
1853 functions which are exported. Fix the collection of type warnings
1854 that surfaced, including a number of functions that didn't
1855 properly take a GError and some that weren't
1856 const-correct. Involved adding error handling for a few loaders.
1858 * gdk-pixbuf-io.h: Add error reporting to stop_load function
1860 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
1861 a function that fills in the GdkPixbufModule vtable, instead of
1862 looking up all the image functions individually; this means we
1863 can get type safety within modules for the loader functions.
1864 Also it means you don't have to keep the statically compiled and
1865 GModule versions in sync.
1867 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
1869 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
1871 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
1873 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
1876 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
1878 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
1881 2001-01-20 John Harper <jsh@eazel.com>
1883 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
1884 collision between Xlib's RdBitF.c and io-tiff.c
1886 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
1889 [ merged from stable gdk-pixbuf module. Untested, but it
1890 compiles, and works fine in the stable module ]
1892 2001-01-18 Tor Lillqvist <tml@iki.fi>
1894 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
1895 g_win32_get_package_installation_subdirectory() function. No need
1896 to include windows.h.
1897 (gtk_win32_get_installation_directory): Remove this then.
1899 2001-01-01 Havoc Pennington <hp@redhat.com>
1901 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
1902 @LIBTOOL_EXPORT_OPTIONS@
1904 2000-12-30 Tor Lillqvist <tml@iki.fi>
1906 * gdk_pixbuf.def: Update.
1908 2000-12-16 Havoc Pennington <hp@pobox.com>
1910 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
1911 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
1912 (gdk_pixbuf_frame_copy): new function
1913 (gdk_pixbuf_frame_free): new function
1914 (gdk_pixbuf_frame_get_type): new function
1915 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
1917 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
1919 * Makefile.am: Add -avoid-version for all modules.
1921 2000-11-13 Havoc Pennington <hp@redhat.com>
1923 * io-png.c (png_simple_error_callback): fix error message to not
1924 say "save" since it's used for loading
1926 2000-11-11 Hans Breuer <Hans@Breuer.Org>
1928 * gdk-pixbuf-io.c : Fix all function prototype macros for self
1929 contained image handlers (!USE_G_MODULE). Files to save should
1930 be opened in binary mode, fopen(s, "wb").
1932 * io-xpm.c : added HAVE_UNISTD_H condition
1934 2000-11-11 Tor Lillqvist <tml@iki.fi>
1936 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
1938 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
1939 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
1940 mktemp() and open()).
1942 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
1944 2000-11-01 Havoc Pennington <hp@pobox.com>
1946 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
1947 a pixbuf pointing to a subregion of another pixbuf.
1949 2000-10-16 Tor Lillqvist <tml@iki.fi>
1951 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
1953 2000-10-16 Havoc Pennington <hp@redhat.com>
1955 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
1956 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
1957 add error reporting here also

1972 * gdk-pixbuf-io.h: Add GError** to load_increment and load
1975 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
1976 a G_FILE_ERROR if we fail to write or close the file.
1978 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
1979 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
1980 the GError naming rules. Add GError** to load functions.
1982 2000-10-06 Havoc Pennington <hp@redhat.com>
1984 * gdk-pixbuf.h: add GdkPixbufAlphaMode
1986 2000-10-06 Havoc Pennington <hp@redhat.com>

2151 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
2153 * makefile.mingw.in: List loaders alphabetically. Add the wbmp

2159 2000-07-27 Elliot Lee <sopwith@redhat.com>
2161 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
2162 gdk_pixbuf_get_named_module() function to facilitate above change
2163 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
2164 Implement loader for WBMP format.
2165 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
2167 2000-07-23 Tor Lillqvist <tml@iki.fi>
2172 * pixops/makefile.mingw.in
2173 * pixbuf_*.def: New files.
2176 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
2178 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
2179 New function, to get the GTK+ installation directory from
2180 the Windows Registry, where the installation program
2181 for whatever software includes GTK+ has stored it.
2183 Used to avoid having hardcoding the directory where to look for
2184 loaders. This function is needed by gtk, too, so it should
2185 really be just in one place. Maybe a small static library
2186 one level up from here?
2188 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
2189 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
2190 Open file in binary mode. This *is* standard C. (No-op on Unix,
2193 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
2195 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
2196 mktemp() and open().
2197 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
2199 * pixops/*.S: The Gas from mingw32 doesn't like the .type
2200 pseudo-op. Conditionalise on __MINGW32__, but probably
2201 should conditionalise on Gas version instead? Or could we
2202 do without .type on all systems?
2204 * pixops/timescale.c: Use g_get_current_time()
2205 instead of gettimeofday().
2207 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
2209 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
2211 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
2213 * gdk-pixbuf.c: Add <string.h> include.
2215 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
2217 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
2218 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
2219 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
2220 use g_object_new() instead of g_type_create_instance() which
2221 is a private function for fundamental type implementations.
2223 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
2225 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
2226 soname scheme for gdk-pixbuf.
2228 2000-06-21 Havoc Pennington <hp@pobox.com>
2230 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
2231 (i.e. derivation is not allowed, and there are no virtual methods
2233 (gdk_pixbuf_preinit): Call g_type_init() here.
2234 (gdk_pixbuf_init): Add a user-friendly init function, for users
2235 of standalone gdk-pixbuf
2237 * gdk-pixbuf-animation.c: Convert to GObject, in the same
2238 way GdkPixbufAnimation was done.
2240 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
2241 gdk_pixbuf_finalize() from API, since these are broken and don't
2242 make sense with new GObject stuff.
2244 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
2246 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
2247 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
2250 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
2252 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
2253 so I needed something to warm my thighs. Running plain infinite
2254 loops on your laptop to make it hot is not very much fun. A demo
2255 of the gdk-pixbuf scaling functions is way better, and looks
2258 * configure.in (AC_OUTPUT): Added the demo Makefile.
2260 * Makefile.am (SUBDIRS): Added the demo directory.
2262 2000-06-09 Larry Ewing <lewing@helixcode.com>
2264 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
2265 setjmp for the png error handler. It seems setting the error
2266 handling functions does not avoid the jump, and so not calling
2267 setjmp was causing the incremental loader to jump into lala land.
2268 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
2269 not sure this one is actually required but the docs say it must be
2270 set for every call to a png_* function.
2271 Also changed the comment to reflect the fact that setting the
2272 error handlers does _not_ avoid the longjmp.
2274 2000-06-06 Larry Ewing <lewing@helixcode.com>
2276 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
2277 take frame offest into account when trying to calculate the
2278 animation bbox. Also set the width to the width not the height.
2279 (gdk_pixbuf_loader_animation_done): cycle over the frames to
2280 calculate bbox because now we finally have all the offset
2281 information for each frame.
2283 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
2285 * configure.in: add some gtk parameters to the
2286 GDK_PIXBUF_LIBÃ�²S and GDK_PIXBUG_INCLUDEDIR vars. One more
2287 fight in my crusade for strange prefix compile...
2289 2000-05-30 Not Zed <NotZed@HelixCode.com>
2291 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
2292 Initialise the error handler exit routine to our own. Note this
2293 means that every function that accesses the jpeg lib on this
2294 object MUST do a setjmp.
2295 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
2296 lib for handling fatal error.
2297 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
2298 your applications dont quit if there's a jpeg error!
2300 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
2302 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
2303 from Frank de Lange <frank@unternet.org>.
2305 2000-05-09 Darin Adler <darin@eazel.com>
2307 * gdk-pixbuf/test-gdk-pixbuf.c:
2308 Fixed includes to get rid of accidental GNOME dependency.
2310 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
2311 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
2313 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
2315 * configure.in: Bumped version number to 0.8.0.
2317 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
2318 file was not being distributed.
2320 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
2322 2000-05-09 Darin Adler <darin@eazel.com>
2324 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
2325 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
2326 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
2327 formats to 32-bit formats to re-use the high bits of the color values
2328 so that white maps to full white.
2330 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
2332 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
2333 detailed information about the structure and algorithms
2334 of pixops so people can fix it instead of breaking it.
2336 2000-05-04 Darin Adler <darin@eazel.com>
2338 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
2339 (composite_pixel), (composite_line):
2340 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
2341 Now that Owen explained the algorithm, I think I implemented it
2342 right for the cases where the destination pixbuf is not opaque.
2343 The test does seem to confirm it.
2345 2000-05-04 Darin Adler <darin@eazel.com>
2347 * gdk-pixbuf/.cvsignore:
2348 * gdk-pixbuf/Makefile.am:
2349 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
2350 (load_pixel), (simple_composite_test_one),
2351 (simple_composite_test_one_type), (simple_composite_test), (main):
2352 Added some tests of composite to highlight problems in the old
2353 implementation. These tests run without any user interaction.
2354 Just do "make check".
2356 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
2357 (composite_pixel), (composite_line): Fix composite to do a textbook
2358 "A over B" composite. This was clearly the intent, and it was easy
2359 to fix the code to do it. (Note to those that read my earlier tries
2360 at a patch; this version fixes typos that were present in all
2361 my patch attempts. I checked the final version by adding more tests.)
2363 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
2365 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
2366 offset y coordinate accordining to render_y0.
2368 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
2371 2000-04-22 James Henstridge <james@daa.com.au>
2373 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
2374 package to the devel package. The only file installed in bin is
2375 gdk-pixbuf-config, which belongs in -devel. This should allow having
2376 multiple versions of the main gdk-pixbuf package installed.
2378 2000-04-17 Karl Eichwalder <ke@suse.de>
2380 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
2381 Reported by Jens Finke.
2383 2000-04-14 Tomasz KÃ�³opczko <kloczek@pld.org.pl>
2385 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
2386 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
2388 2000-04-13 James Henstridge <james@daa.com.au>
2390 * configure.in: when performing the configure check to see if
2391 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
2392 rather than the other way round. Also, call AC_MSG_RESULT in the
2393 even that dynamic modules were not supported.
2395 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
2397 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
2398 hook to the last unref operation.
2400 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
2401 function to set the last unref handler for a pixbuf.
2402 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
2403 It calls the pixbuf's destroy notification function and frees the
2404 GdkPixbuf structure itself.
2405 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
2408 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
2409 for the last unref handler and its user data.
2411 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
2412 g_new0() to allocate the pixbuf.
2414 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
2415 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
2416 was not specifying the `frame' argument.
2418 * gdk-pixbuf/gdk-pixbuf-animation.c
2419 (gdk_pixbuf_animation_get_width): Fixed docstring.
2420 (gdk_pixbuf_animation_get_height): Likewise.
2421 (gdk_pixbuf_animation_get_num_frames): Likewise.
2422 (gdk_pixbuf_animation_get_frames): Likewise.
2424 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
2427 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
2429 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
2431 * doc/tmpl/refcounting.sgml: Updated with the information about
2432 the last unref handler.
2434 * doc/tmpl/*.sgml: Markup tweaks.
2436 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
2437 update the libtool version number for libgnomecanvaspixbuf as
2439 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
2440 as well, or the old ones won't work with the new stuff. Also,
2441 renamed the modules as follows.
2443 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
2444 modules are called "libpixbufloader-<format>.so" instead of
2445 "libpixbuf-<format>.so". They needed renaming so that the new
2446 loaders won't overwrite the old ones; even with the versioning
2447 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
2450 2000-04-12 Paolo Molaro <lupus@debian.org>
2452 * .cvsignore, src/.cvsignore: shut up cvs.
2454 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
2456 Most of this patch is based on a patch by Havoc Pennington
2457 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
2458 remove the libart dependency.
2460 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
2461 (GdkColorspace): New enum that for now only contains
2463 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
2464 notification function.
2465 (GdkInterpType): New num with interpolation types.
2467 * *.[ch]: Replace the libart stuff with our own stuff.
2469 * pixops/*.[ch]: Likewise.
2471 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
2472 declarations of the GdkPixbuf structures.
2474 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
2476 (gdk_pixbuf_get_format): Constify.
2477 (gdk_pixbuf_get_n_channels): Constify.
2478 (gdk_pixbuf_get_has_alpha): Constify.
2479 (gdk_pixbuf_get_bits_per_sample): Constify.
2480 (gdk_pixbuf_get_pixels): Constify.
2481 (gdk_pixbuf_get_width): Constify.
2482 (gdk_pixbuf_get_height): Constify.
2483 (gdk_pixbuf_get_rowstride): Constify.
2485 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
2488 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
2489 bits_per_sample argument; currently only 8 bits per sample are
2492 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
2494 (gdk_pixbuf_frame_get_x_offset): New accessor.
2495 (gdk_pixbuf_frame_get_y_offset): New accessor.
2496 (gdk_pixbuf_frame_get_delay_time): New accessor.
2497 (gdk_pixbuf_frame_get_action): New accessor.
2499 * gdk-pixbuf/gdk-pixbuf-render.c
2500 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
2501 mask rectangle for pixbufs without an alpha channel, set the
2502 *mask_return to NULL.
2504 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
2506 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
2508 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
2509 preconditions. Maybe we should also check for the colorspace,
2510 bits per pixel, and such.
2511 (gdk_pixbuf_composite): Likewise.
2512 (gdk_pixbuf_composite_color): Likewise.
2513 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
2514 cannot allocate the new pixbuf.
2515 (gdk_pixbuf_composite_color_simple): Likewise.
2517 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
2518 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
2521 * gdk-pixbuf/io-bmp.c: Fix includes.
2523 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
2528 * configure.in: Removed checks for libart.
2530 * gdk-pixbuf/Makefile.am: Removed references to libart.
2531 (noinst_HEADERS): Added gdk-pixbuf-private.h.
2533 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
2534 the version number of the libtool library to indicate that this
2535 definitely is not compatible with the old usage. I know you love
2538 * configure.in: Bumped version number to 0.7.0.
2542 * gdk-pixbuf-config.in (--libs): We no longer require libart.
2544 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
2546 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
2548 2000-04-06 Jonathan Blandford <jrb@redhat.com>
2550 * gdk-pixbuf/testanimation.c (main): add more info to the
2551 testanimation frames.
2553 2000-04-04 Ettore Perazzoli <ettore@helixcode.com>
2555 * gdk-pixbuf/gdk-pixbuf-animation.c
2556 (gdk_pixbuf_animation_get_width): New accessor function.
2557 (gdk_pixbuf_animation_get_height): New accessor function.
2558 (gdk_pixbuf_animation_get_num_frames): New accessor function.
2559 (gdk_pixbuf_animation_get_frames): New accessor function.
2561 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
2563 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
2564 is private information, and the art_pixbuf will go away soon.
2566 2000-03-31 Mark Crichton <crichton@gimp.org>
2568 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
2569 and gdk_pixbuf_get_artpixbuf accessor functions.
2571 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
2573 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
2574 gboolean instead of int.
2576 2000-03-29 Radek Doulik <rodo@helixcode.com>
2578 * gdk-pixbuf/gdk-pixbuf-animation.c
2579 (gdk_pixbuf_animation_new_from_file): same as below
2581 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
2582 height in GdkPixbufAnimation
2584 2000-03-28 Radek Doulik <rodo@helixcode.com>
2586 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
2587 context->frame_done_func and context->anim_done_func to make
2588 progressive animation loading work
2590 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
2591 added priv->pixbuf = NULL as pixbuf is now in frame (and to make
2592 gdk_pixbuf_loader_prepare happy)
2593 (gdk_pixbuf_loader_frame_done): update animation bbox
2595 * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to
2598 2000-03-27 Radek Doulik <rodo@helixcode.com>
2600 * gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width
2601 instead of width and height
2603 2000-03-27 Owen Taylor <otaylor@redhat.com>
2605 * gdk-pixbuf/pixops/pixops.c: Fix problem with
2606 precendence of >> and & which was keeping composite_color
2607 from working with non-gray images.
2609 2000-03-08 Jonathan Blandford <jrb@redhat.com>
2611 * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context.
2612 (gdk_pixbuf__gif_image_load_animation): free the context.
2614 2000-03-06 Arjan van de Ven <arjan@fenrus.demon.nl>
2616 * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a
2617 mis-interpretation of the Microsoft documentation. Now
2618 it can load .BMP files that are not generated by The Gimp
2621 2000-03-01 Mark Crichton <crichton@gimp.org>
2623 * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
2624 fix the last auto* build bug (where we have libart, but no
2627 * gdk-pixbuf/Makefile.am: Same.
2629 2000-02-28 Matt Wilson <msw@redhat.com>
2631 * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,
2632 s/unsigned short/guint16/g, s/unsigned char/guint8/g
2634 2000-02-26 Federico Mena Quintero <federico@helixcode.com>
2636 * README: We don't require libgif/ungif nor libXpm.
2638 * NEWS: This was outdated, so updated it.
2640 2000-02-25 Federico Mena Quintero <federico@helixcode.com>
2642 * gdk-pixbuf.m4: Use the correct name for
2643 gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing
2646 2000-02-21 Federico Mena Quintero <federico@helixcode.com>
2648 * configure.in (GDK_PIXBUF_MINOR): Bumped version number to 0.6.0.
2650 * doc/compiling.sgml: New appendix documenting the gdk-pixbuf
2651 library's particular options to configure.in.
2653 * doc/gdk-pixbuf.sgml: Include compiling.sgml appendix via an
2656 * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml.
2658 * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment):
2659 Fixed typo in prototype name.
2661 * configure.in: Changed duplicated AC_MSG_CHECKING message to
2662 something more meaningful; now it is "checking whether dynamic
2665 * gdk-pixbuf/pixops/Makefile.am (noinst_PROGRAMS): Do not install
2666 the timescale program.
2668 Integrated Miguel de Icaza's <miguel@gnu.org> patch for optionally
2669 creating a single static library with all the image format modules

3041 animation functions here.
3042 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
3043 animation if the loader does not support multiframe loading and

3056 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
3059 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
3060 with a reference count of 1.
3062 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
3063 gdk-pixbuf-animation.c.
3065 * doc/tmpl/animation.sgml: Populated. It is still missing a
3066 description of the overlay modes.

3082 1999-12-23 Havoc Pennington <hp@pobox.com>
3084 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
3085 set to NULL here (specifically context->animation) was not being
3086 set to NULL. use g_new0() to alloc the struct.
3088 1999-12-20 Jonathan Blandford <jrb@redhat.com>
3090 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
3091 correctly. Progressive loading needs some work, but that all
3092 needs doing from the gdk-pixbuf-loader end, not here.
3094 1999-12-17 Jonathan Blandford <jrb@redhat.com>
3096 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
3097 moved the file here. It seems natural to put this function here,
3098 as that's where the gdk_pixbuf_new_from_file function is, but it's
3099 still a little convoluted. The source files might be played with
3102 1999-12-14 Jonathan Blandford <jrb@redhat.com>
3104 * gdk-pixbuf/gdk-pixbuf-loader.c
3105 (gdk_pixbuf_loader_get_animation): Gets the animation from the

3112 Shaw <joe@off.net> for pointing this out.
3114 1999-12-13 Federico Mena Quintero <federico@redhat.com>
3116 * gdk-pixbuf/gnome-canvas-pixbuf.c
3117 (gnome_canvas_pixbuf_class_init): Renamed arguments to
3118 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for

3148 Filled in body of function.
3149 (rgbconvert): Added GdkColormap parameter, and to all conversion
3151 (convert_real_slow): New function - should convert ANY visual/data
3152 format properly, but it aint fast. Used as a fallback when an
3153 optimised routine wont match.
3154 (rgbconvert): Do very specific tests on the data format to verify
3155 properly if the optimised version will do, otherwise use the
3156 fallback function for all other data formats.
3158 * gdk-pixbuf/Makefile.am: Re-enabled building of
3159 textpixbuf-drawable.
3161 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
3162 gdk_pixbuf_get_from_drawable().
3164 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
3166 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red

3173 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
3174 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
3175 checks and API definition. The body needs filling in and it needs
3176 to do the Right Thing(tm) for pixmaps plus the given colormap and
3177 windows and their own colormaps.
3179 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for

3198 1999-12-07 Martin Baulig <martin@home-of-linux.org>
3200 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
3201 include $(GNOME_LIBS) here.
3203 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
3205 Added missing "include <string.h>" to:

3210 1999-12-06 Federico Mena Quintero <federico@redhat.com>
3212 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
3215 1999-12-05 Federico Mena Quintero <federico@redhat.com>
3217 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
3218 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
3219 want, send me a patch to do the conditional stuff properly.
3220 Otherwise, please read the GNOME Programming Guidelines,
3221 especially the "CVS policies" section.
3223 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
3225 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.

3235 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
3237 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
3239 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
3242 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files

3254 explain this function better.
3256 1999-12-02 Federico Mena Quintero <federico@redhat.com>
3258 Source files moved from src/ to gdk-pixbuf/, to be consistent with

3333 1999-11-29 Owen Taylor <otaylor@redhat.com>
3335 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
3336 Keep the mask around until after we draw ... since
3337 the GC changes aren't flushed to the X server until we
3338 draw, destroying it before that may result in BadPixmap
3341 1999-11-30 Havoc Pennington <hp@pobox.com>
3343 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
3345 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
3347 1999-11-29 Federico Mena Quintero <federico@redhat.com>
3349 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
3350 should be made conditional, not blindly commented out.
3352 1999-11-29 Jonathan Blandford <jrb@redhat.com>
3354 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
3355 handle .ico files. Cool.
3357 1999-11-24 Jonathan Blandford <jrb@redhat.com>
3359 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
3362 1999-11-24 James Henstridge <james@daa.com.au>
3364 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
3365 top builddir rather than src. This still builds fine, and does not
3366 get gtk-doc into an infinite loop when trying to find all the source
3369 1999-11-23 Jonathan Blandford <jrb@redhat.com>
3371 * Removed #PRAGMA } from headers. Also, make compile if you don't
3372 have it installed, already.
3374 1999-11-22 Federico Mena Quintero <federico@redhat.com>
3376 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
3377 temporary buffer to the size of the interesction of the bounding
3378 box and the expose area, not the whole expose area. This speeds
3381 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
3382 not paint black on the mask, since we already cleared it in a
3383 single gdk_draw_rectangle() operation.
3385 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
3387 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
3389 1999-11-22 Havoc Pennington <hp@pobox.com>
3391 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
3392 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
3393 dependencies to LIBADD variables for loadable modules. Necessary
3394 for a Java dynamic loading thing to be able to figure it out.
3396 1999-11-22 Havoc Pennington <hp@pobox.com>
3398 * src/io-png.c (image_load_increment): Call the update_area
3399 callback depending on the number of rows loaded in this increment.
3401 * src/testpixbuf.c (main): slow down the progressive load demo
3403 1999-11-16 Havoc Pennington <hp@pobox.com>
3405 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
3407 1999-11-22 Jonathan Blandford <jrb@redhat.com>
3409 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
3410 for srcdir != buildir != . Beats me why; I can't figure it out.
3411 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
3413 1999-11-21 Jonathan Blandford <jrb@redhat.com>
3415 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
3416 <arjan@fenrus.demon.nl>
3418 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
3420 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
3421 Rework/reorder of the code. Each case has been separated into
3422 another function; its big but it should be quick.
3423 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
3424 opaque alpha information. Not all depths/formats have been
3425 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
3427 1999-11-17 Larry Ewing <lewing@gimp.org>
3429 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
3430 implement the bounds method correctly.
3431 (compute_viewport_affine): compute the affine need to fit the
3432 image within the viewport given by the args.
3433 (compute_render_affine): call compute_viewport_affine.
3435 1999-11-16 Havoc Pennington <hp@pobox.com>
3437 * src/gdk-pixbuf-drawable.h: Use includes from the current
3438 directory, not the system directory.
3440 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
3442 * src/testpixbuf-drawable.c: use includes from the current directory
3443 rather then from the system include directory as gdk-pixbuf
3444 includes are not yet installed when this is compiled.
3446 1999-11-13 Cody Russell <bratsche@dfw.net>
3447 * src/testpixbuf-drawable.c: Added a test program for drawable
3450 * src/Makefile.am: Build testpixbuf-drawable.
3452 1999-11-12 Cody Russell <bratsche@dfw.net>
3454 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.

3465 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3467 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
3470 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
3471 correctly. Patch from Arjan to do so.
3473 1999-11-10 Michael Fulbright <drmike@redhat.com>
3475 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
3478 * src/testpixbuf.c: Added final queued draw when done loading image.
3480 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3482 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
3485 1999-11-10 Federico Mena Quintero <federico@redhat.com>

3490 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3492 * src/io-png.c: Fixed some incompatible pointer initializations.
3494 * src/io-jpeg.c (image_load_increment): Remove unused variable.
3496 1999-11-09 Michael Fulbright <drmike@redhat.com>
3498 * src/testpixbuf.c: Fixed it to use timeout to read from file
3499 for progressive loading. Set TBF_KBPS=n, where n is the number of
3500 kilobytes/second to simulate in downloading. n has to be an integer.
3502 * src/io-jpeg.c: Slight cosmetic cleanup.
3504 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
3505 PBM loading has a similar problem and will address tomorrow.
3507 1999-11-09 Havoc Pennington <hp@pobox.com>
3509 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
3510 gdk-pixbuf-drawable stuff.
3512 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3514 * configure.in: Bumped version number to 0.4.
3516 1999-11-09 Michael Fulbright <drmike@redhat.com>
3518 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
3519 all types of PNM files now.
3521 * src/io-jpeg.c (image_load_increment): Figured out problem with
3522 loading Progressive JPEG's progressively (say that 10 times fast).
3523 Currently for Progressive JPEG's the entire image is loaded before
3524 it is displayed. libjpeg supports a fancier mechanism which I may
3527 With these changes all JPEG formats appear to load properly for me.
3529 1999-11-08 Jonathan Blandford <jrb@redhat.com>
3531 * src/io-ras.c (image_load_increment): Final patch from Arjan.
3532 Seems to do progressive loading.
3534 1999-11-08 Michael Fulbright <drmike@redhat.com>
3536 * src/io-pnm.c image_load (): Fixed so we do not create a separate
3537 pixel buffer when reading in image - we reuse the pixel data in
3538 the GdkPixbuf structure instead.
3540 1999-11-08 Michael Fulbright <drmike@redhat.com>
3542 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
3543 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
3544 I can't seem to find a utility to convert into this format.
3545 Next is to add progressive loading support for the PNM format.
3547 1999-11-07 Federico Mena Quintero <federico@redhat.com>
3549 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation

3559 * src/io-ras.c (image_load): new file from Arjan van de Ven
3560 <arjan@fenrus.demon.nl> to begin the ras loader.
3562 1999-11-05 Federico Mena Quintero <federico@redhat.com>

3583 * src/io-jpeg.c: Prettied up code slightly.
3584 * src/io-pnm.c: Start of pnm loader (from file and progressively).
3585 Doesn't do much yet (will finish tomorrow).
3586 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
3588 1999-11-04 Federico Mena Quintero <federico@redhat.com>

3597 docs, explain what a dither offset is for.
3598 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
3599 this function vs. gdk_pixbuf_render_to_drawable().
3601 1999-11-04 Havoc Pennington <hp@pobox.com>
3603 * configure.in: Use libart-config correctly; find gnome-config
3604 separately. Fix GNOME_LIBS to be correct in "no gnome installed
3607 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
3610 Patch untested in the inside-gnome-libs case, I need to commit
3611 then check out to the gnome-libs I'm using.

3662 bugginess in local buffering code. Handles grayscale jpegs
3665 * src/io-jpeg.c (image_load_stop): Was freeing local context
3666 for jpeg library before calling jpeg_decompres_finish ().

3714 1999-11-03 Michael Fulbright <drmike@redhat.com>
3716 * src/io-jpg.c (image_load_increment): Fixed code which moved
3717 buffer around as new data comes in to work properly. JPEG progressive
3718 loading should be working now except for grayscale JPEG's, which I
3719 will look into next.
3721 1999-11-03 <sopwith@redhat.com>
3722 * src/testpixbuf.c: A GtkFunction needs to return a value for
3723 deterministic behaviour. Also put dot printing back in.
3725 1999-11-03 <jrb@redhat.com>
3727 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
3730 1999-11-02 Cody Russell <bratsche@dfw.net>

3735 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3737 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
3738 for interlacing and progressive loading.

3742 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
3744 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3746 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
3747 It's a little slow though. )-:
3749 1999-11-02 Elliot Lee <sopwith@redhat.com>
3750 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the
3751 arguments to the write/load_increment operations const-correct.
3753 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3755 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
3756 Implemented the ::point() method. We do a simple containment test
3757 instead of a full distance calculation since the canvas is going
3758 to change to that scheme, anyways.
3760 1999-11-02 Elliot Lee <sopwith@redhat.com>
3762 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size
3763 of the chunks that are read from the input file.
3765 1999-11-02 Larry Ewing <lewing@gimp.org>
3767 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
3769 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
3772 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3774 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
3775 affine computation code from ::draw() to here, since it is needed
3776 by ::point() as well.
3778 1999-11-02 Elliot Lee <sopwith@redhat.com>
3780 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
3781 three functions, and eliminate duplication of code from write()
3782 and close(). Also fix bug where the 128-byte header was being
3785 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3786 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
3787 bounding box computation.
3789 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3791 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
3792 Drawing affines seem to work. Bounding box is fubared. ::point()
3793 is not implemented. This is a work in progress.
3795 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
3798 * configure.in: Sigh. We need to link in libgnomeui for the
3799 canvas stuff. This mess will disappear when gdk-pixbuf gets
3800 folded into gnome-libs.
3802 1999-10-30 Jonathan Blandford <jrb@redhat.com>
3804 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
3805 the right size, at a minimum, even if the image is squished and
3807 (ReadImage): lets get the offset right. This will let transparent
3810 1999-10-29 Michael Fulbright <drmike@redhat.com>
3812 * src/io-jpeg.c: image_load_increment(): Fixed bug when
3813 image width was not a multiple of 4 - always use the
3814 gdk_pixbuf rowstride to increment pointers!
3816 1999-10-29 Michael Fulbright <drmike@redhat.com>
3818 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
3819 Currently does not handle either progressive jpeg files (jpeg
3820 files with multiple scans at different quality settings), but
3821 I plan on adding this support soon. These are fairly rare in
3822 my experience, so it shouldn't slow people down too much.
3823 Grayscale jpegs also don't work but that should be easy to fix.
3825 1999-10-29 Michael Fulbright <drmike@redhat.com>
3827 * src/testpixbuf.c: Added title to windows so you can identify
3828 progressive and file windows.
3830 1999-10-29 Michael Fulbright <drmike@redhat.com>
3832 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
3833 load the image handler when we determine the image type.
3835 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
3836 previously static function load_image_handler () to
3837 a public function gdk_pixbuf_load_module (). It is needed in
3838 gdk-pixbuf-loader.c to load image handler modules. This function
3839 is different from gdk_pixbuf_get_module (), which only returns
3840 a reference to the required handler, because it actually loads
3841 the handler into memory. Both actions should possibly be combined
3842 in a convenience function since one w/o the other doesn't seem to
3845 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3847 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
3850 1999-10-28 Federico Mena Quintero <federico@redhat.com>
3852 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
3853 function to render a portion of a pixbuf to a drawable. Ignores
3854 alpha information and takes in a GC.
3855 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
3856 portion of a pixbuf to a drawable. It automatically creates a GC
3857 and a clipping mask for alpha pixbufs.
3859 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3861 * src/gdk-pixbuf.h: turned convenience macros into convenience
3862 functions so some error checking could be added.
3864 * src/io-tiff.c (image_load_increment): started work on the tiff
3865 non-incremental loader.
3866 (image_begin_load): Finished the incremental loader.
3868 * src/io-gif.c (image_load_increment): started work on the gif
3871 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
3873 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3875 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
3876 function to threshold a pixbuf's alpha channel into a bitmap.
3878 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
3879 contemplate future extensions to ArtPixBuf's formats.
3881 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
3883 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
3884 macros to fetch the ArtPixBuf's fields.
3886 1999-10-27 Havoc Pennington <hp@pobox.com>
3888 * src/testpixbuf.c (main): Display the progressive load
3890 * src/io-png.c (setup_png_transformations): Break transformation
3891 code into separate function
3892 (png_info_callback): Use setup_png_transformations
3894 1999-10-27 Havoc Pennington <hp@pobox.com>
3896 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
3897 properly whether the XPM module has already been loaded
3898 (gdk_pixbuf_new_from_file): Check properly if loader module
3899 was already loaded (was checking if load symbol was present
3900 in order to decide whether to re-load; should check module !=
3901 NULL, then load != NULL)
3902 (image_handler_load): Check in present working directory,
3903 makes it easier to debug for now
3904 (file_formats): This array initializer was seriously on crack,
3905 was assigning a function pointer to a GModule*
3907 * src/testpixbuf.c (main): Change type of pixbuf_loader to
3910 1999-10-27 Havoc Pennington <hp@pobox.com>

3918 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
3919 GdkPixbufLoader, not a GtkObject.
3920 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
3921 (gdk_pixbuf_loader_get_type): Documented.
3922 (gdk_pixbuf_loader_class_init): Initialize the parent class
3924 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
3925 class destroy function.
3926 (gdk_pixbuf_loader_new): Documented.
3927 (gdk_pixbuf_loader_finalize): Call the parent class finalize
3929 (gdk_pixbuf_loader_write): Use size_t for count.
3931 1999-10-27 Michael Fulbright <drmike@redhat.com>
3933 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
3934 logic so we only try to close loader if it wasn't previously closed.
3936 1999-10-27 Michael Fulbright <drmike@redhat.com>
3938 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of

3965 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
3967 1999-10-22 Havoc Pennington <hp@pobox.com>
3969 * src/io-xpm.c (mem_buffer): Clean up stupid
3970 increment-inside-array-dereference thing
3972 * src/testpixbuf.c: Add XPM data tests.
3974 * src/io-xpm.c: Make the XPM data buffer const, fix const
3975 correctness throughout the code.
3977 1999-10-22 Havoc Pennington <hp@pobox.com>
3979 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

3987 function, loads pixbuf from xpm data
3988 (image_handler_load): Add g_return_if_fail() to ensure the same
3989 module isn't loaded twice. Add g_module_symbol() to scan for XPM
3992 1999-10-22 Federico Mena Quintero <federico@redhat.com>
3994 * src/io-png.c (image_load): Patch from Kristian Hogsberg
3995 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
3996 buffers; the rows can be read in directly into the main pixel
3999 1999-10-20 Federico Mena Quintero <federico@redhat.com>
4001 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
4003 1999-10-20 Federico Mena Quintero <federico@redhat.com>
4005 * configure.in: Bumped version number to 0.3.
4007 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
4008 version number for the library.
4010 1999-10-20 Federico Mena Quintero <federico@redhat.com>
4012 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
4013 all memory management of the buffer is done by libart.
4015 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
4016 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
4018 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
4019 terms of the libart functions. Removed the old code.
4021 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
4022 symbols. Saving will not be implemented in GdkPixbuf.
4024 * src/io-gif.c: Removed the saving stub.
4025 (image_load): Fixed memory management to fail gracefully if we run
4026 out of memory while loading the image. Close the gif file when we
4027 are done. This still needs more error handling for the DGif
4030 * src/io-jpeg.c (image_load): Some robustness fixes.
4032 * src/io-png.c: Removed the saving stuff.
4033 (image_load): Some memory management fixes.

4043 * autogen.sh: use subautogen.sh
4045 1999-10-18 Federico Mena Quintero <federico@redhat.com>
4047 * src/*: Reindented to use the GNOME Indentation. Renamed
4048 GdkPixBuf to GdkPixbuf, for consistency with the function names
4049 (and it is also easier to type) :-)
4051 1999-10-18 Havoc Pennington <hp@pobox.com>
4053 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
4055 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
4057 1999-10-18 Havoc Pennington <hp@pobox.com>
4059 * Makefile.am (SUBDIRS): Remove "macros"
4061 * configure.in: Don't use GNOME_INIT, handle case where we are
4062 inside gnome-libs. AM_PATH_GTK for the GIF test
4064 * src/Makefile.am: Change flags to work without libgnomeui,
4065 comment out testpixbuf for now
4067 1999-10-18 Federico Mena Quintero <federico@redhat.com>
4069 * configure.in: Use $GTK_LIBS as the extra libs when checking for
4070 libgif/libungif, as they need the X libraries. Fixes bug #2472.
4072 1999-10-10 Cody Russell <bratsche@dfw.net>
4073 * src/gdk-pixbuf-drawable.c: core function now determines whether
4074 the requested geometry is on screen or not, and if some is not
4075 then the request is clamped to geometry that is on the screen.
4077 Changed 'pixbuf' to 'art_pixbuf' in core function.
4079 1999-10-08 Michael Fulbright <drmike@redhat.com>
4081 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.
4083 * src/testpifbuf: Changed test program to display cdrom from rgb data
4084 if no filename given to test program.
4086 1999-10-07 Cody Russell <bratsche@dfw.net>
4087 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
4088 them, but I wrote them).
4090 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
4093 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
4094 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

4114 * src/io-tiff.c (image_load): ditto + fix leak
4116 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
4117 crashes this module ( add warning :-)
4119 * src/io-bmp.c (image_load): ditto.
4121 * src/io-gif.c (image_load): ditto.
4123 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
4125 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
4126 it doesn't crash scaling with alpha.
4128 1999-09-17 Federico Mena Quintero <federico@redhat.com>
4130 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
4132 * src/io-gif.c (image_load): Likewise.
4134 * src/io-jpeg.c (image_load): Likewise.
4136 * src/io-png.c (image_load): Likewise.

4151 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
4152 to unallocated memory (row_ptr), and fixed its type as well. Take
4153 into account the ArtPixbuf's rowstride when assigning the row
4156 * src/gdk-pixbuf.c: Fixup includes.
4158 * src/gdk-pixbuf-io.c: Likewise.
4160 Sat Jul 31 19:19:47 CEST 1999

4163 * src/io-png.c: Fixed two obvious C syntax bugs
4165 1999-07-29 Mark Crichton <crichton@gimp.org>
4167 * src/io-png.c (image_save): Added PNG saving function
4169 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
4170 image_save(GdkPixBuf *p, FILE *f, ...)
4173 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
4175 * src/Makefile.am (*_LIB): Only build the relevant loaders which
4176 require extra libraries if we actually have those libraries.
4178 1999-07-23 Richard Hestilow <hestgray@ionet.net>
4180 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
4181 * gdk_pixbufConf.sh.in: Added for gnome-config

4185 1999-07-20 Mark Crichton <crichton@gimp.org>
4187 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
4188 calculation needs to be done.
4190 1999-07-18 Larry Ewing <lewing@gimp.org>
4195 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
4196 error cases but one or two in the common case. There are probably
4197 a few small ones left.
4199 1999-07-18 Mark Crichton <crichton@gimp.org>
4201 * configure.in: removed version.h.
4203 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
4206 1999-07-17 Mark Crichton <crichton@gimp.org>
4208 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
4209 (gdk_pixbuf_rotate): Added pixbuf rotation code.

4212 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
4215 1999-07-16 Larry Ewing <lewing@gimp.org>
4217 * src/testpixbuf.c (expose_func): reverted the expose everything
4218 changes, I'm not sure why these went in.
4219 (config_func): bring this up to date with the new pixbuf_scale
4222 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
4223 loading code so that poeple can diagnose problems better.
4225 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
4226 no longer allocates a new pixbuf, which make things nicer for the
4227 rest of the code. Unfortunately there is still a problem with
4228 scaling rgba images.
4230 1999-07-16 Mark Crichton <crichton@gimp.org>
4232 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
4233 calls gdk_pixbuf_scale. However, something is not working.
4234 N.B.: current pixmap is now stored in user_data with a key of
4237 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
4238 Something is still borked, however.
