        (gdk_pixbuf_loader_class_init): Add size_prepared signal.
        (gdk_pixbuf_loader_set_size): New function.

        * io-tiff.c (tiff_set_error): Handle global_error == NULL
        better.
        (tiff_image_parse): Don't trust TIFFRGBAImageBegin to set
        the "put" routine.  (Fixes #87384)
        (gdk_pixbuf__tiff_image_stop_load): Don't call TIFFClose too 
        early.

2002-07-02  Matthias Clasen  <maclas@gmx.de>

        Miscellaneous bmp loader fixes (#85448, #86286, #86287):
        
        * io-bmp.c (grow_buffer): New function to avoid crashes
        on unchecked reallocs. 
        (DecodeHeader, DecodeColormap, decode_bitmasks,
        DoCompressed): Use grow_buffer instead of g_realloc 
        throughout. Change signatures where necessary to pass the
        errors up.
        (OneLine16): Fix loading of 16bpp BI_RGB bmps. 
        (DoCompressed): Rewritten to properly support BI_RLE4 and

        (gdk_pixbuf__ras_image_load_increment): Handle compressed ras
        images.

        Better colorspace support for the jpeg loader (#61211):

        (gdk_pixbuf__jpeg_image_load,
        gdk_pixbuf__jpeg_image_load_increment): Allocate a pixbuf with
        alpha for 4-channel jpegs and call convert_cmyk_to_rgb for these.

        All of this needs to be merged to GNOME 1.4 gdk-pixbuf.
        
2002-06-28  Sven Neumann  <sven@gimp.org>

        * gdk-pixbuf-csource.c (print_blurb): converted a Tab to spaces.

Thu Jun 13 18:11:11 2002  Owen Taylor  <otaylor@redhat.com>

        * pixops/pixops.c: Fix problem where when no alpha was
        involved, we scaled rather than composited, but then
        went ahead and composited anyways. (#76958, Patch
        from Matthias Clasen). Needs to be merged to GNOME
        1.4 gdk-pixbuf.

2002-06-13  Matthias Clasen  <maclas@gmx.de>

        * io-jpeg.c: Use libjpeg in buffered-image mode in order to
        incrementally display incrementally loaded progressive jpegs.

2002-06-07  Federico Mena Quintero  <federico@ximian.com>

        * io-bmp.c (lsb_32):
        (lsb_16): New functions to fetch 32 or 16-bit little-endian values
        starting at a specific memory location.  We do this instead of
        GINT32_FROM_LE() as the latter is simply dereferences a cast,
        which doesn't work on platforms with alignment requirements.
        Fixes #84083.

2002-06-01  Matthias Clasen  <maclas@gmx.de>

        * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting
        with a C comment - those seem to be not uncommon, e.g. the Gimp 
        produces them.  (#82706)

        * io-xbm.c (read_bitmap_file_data): Don't leak memory on certain
        invalid inputs.
        (gdk_pixbuf__xbm_image_load_real): Don't leak memory on valid inputs.

2002-05-22  Tor Lillqvist  <tml@iki.fi>

        * gdk-pixbuf-io.c (get_libdir): Use GTK_BINARY_VERSION (and not
        GTK_VERSION) in the path to the loaders on Win32, too.

        * Makefile.am: Pass GTK_BINARY_VERSION.

2002-05-22  Federico Mena Quintero  <federico@ximian.com>

        * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
        account!!!  Fixes #82515.

        [This bug is not present in the GNOME 1.4 branch as its XPM loader
        does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
        no row padding and then uses gdk_pixbuf_new_from_data() on it.]

        [IMPORTANT: The comment above is to make my life easier when
        merging stuff across branches.  If you make changes to gdk-pixbuf
        in either branch, please include a comment in the ChangeLog that
        indicates whether this should be merged into the other branch.
        Thanks!]

2002-05-18  Matthias Clasen  <maclas@gmx.de>

        * io-tiff.c (tiff_image_parse): fix packing order on bigendian 
        systems.  (#81702)

        (#78258)

2002-05-07  Michael Natterer  <mitch@gimp.org>

        * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
        conditionally like the dynamic ones so --without-lib<foo> is
        honored when building with --disable-modules. (#66867)

Sun May  5 02:27:01 2002  Soeren Sandmann  <sandmann@daimi.au.dk>

        * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to
        gtk+/tests/)
        * test-loaders.c, test-images.h: remove 

2002-04-24  Matthias Clasen  <maclas@gmx.de>

        * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
        restriction from the description of png tEXt parameters.

        (gdk_pixbuf__png_image_save): If libpng supports it,
        store and retrieve non-ISO8859-1 text as UTF-8.  (#76172)

2002-04-11  Matthias Clasen  <maclas@gmx.de>

        More fixes for #77807:
        
        * io-tga.c (get_contiguous_pixbuf): Helper function to create
        a pixbuf with a contiguous pixel array while being careful about
        overflow. 

        * io-tga.c (fill_in_context, get_image_pseudocolor,
        get_image_truecolor, get_image_grayscale): Use 
        get_contiguous_pixbuf instead of manually allocating image
        storage. 

        * io-xpm.c (pixbuf_create_from_xpm): 
        * io-pnm.c (gdk_pixbuf__pnm_image_load):
        * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
        instead of manually allocating image storage.

2002-04-09  Matthias Clasen  <maclas@gmx.de>

        * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use 
        priv->image_module->module_name instead of image_type which may 
        be NULL.

2002-04-06  Matthias Clasen  <maclas@gmx.de>

        * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
        gdk_pixbuf_new instead of manually allocating image storage. This
        gives us a good rowstride and overflow checks.  (#77807)

2002-04-05  Matthias Clasen  <maclas@gmx.de>

        * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
        the image by using a TIFFRGBAImage{Begin,Get,End} with suitable
        put functions instead of TIFFRGBAImage. And check image dimensions
        for overflow. 

2002-04-03  Matthias Clasen  <maclas@gmx.de>

        * gdk-pixbuf-loader.c (gdk_pixbuf_loader_get_type): Fix a doc typo.

2002-03-29  Matthias Clasen  <maclas@gmx.de>

        * io-png.c (png_simple_error_callback): libpng error handlers must
        not return to their callers, thus longjmp out. This prevents
        annoying stderr output from the default error handler.

2002-03-27  Matthias Clasen  <maclas@gmx.de>

        * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.

        * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
        end_info. Also call png_read_end to check proper ending of the png
        file and catch text chunks after the image data.

2002-03-27  Matthias Clasen  <maclas@gmx.de>

        * io-png.c (gdk_pixbuf__png_image_load,
        gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
        instead of system malloc. 

2002-03-26  Matthias Clasen  <maclas@gmx.de>

        * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.

        * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
        context->buf on error.

        * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
        stop_load even for short images to prevent memleaks.

2002-03-25  Matthias Clasen  <maclas@gmx.de>

        * io-png.c (setup_png_transformations): Changed signature to
        return success and set a GError parameter, adjusted all callers.
        Also work around a possible FPE in libpng and always check that
        the new info is sane.

2002-03-23  Matthias Clasen  <maclas@gmx.de>

        * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
        context->updated_func is NULL during a nonincremental load.
        (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.

2002-03-18  Matthias Clasen  <maclas@gmx.de>

        * io-tga.c: Fix assumptions on rowstride by manually allocating a
        contiguous pixel buffer. Catch buffer overruns in RLE-modi. 
        Support grayscale + alpha (which can be written, but not read (!)
        by the Gimp). 

2002-03-15  Matthias Clasen  <maclas@gmx.de>

        * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.

2002-03-13  Matthias Clasen  <maclas@gmx.de>

        * test-images.h: Add valid_ras_test and invalid_bmp_1.

        * test-loaders.c (main): Add random tests for ras and pnm and an
        invalid bmp which was a crasher until my 2002-03-12 commit.

        * io-pnm.c (gdk_pixbuf__pnm_image_load_increment): Don't unref the
        pixbuf on errors.

        * io-ras.c: Handle some errors.

2002-03-12  Sven Neumann  <sven@gimp.org>

        * gdk-pixbuf.c (gdk_pixbuf_fill): use sequential writes instead of
        calling memcpy(). Simpler and potentially faster. (#70332)

2002-03-12  Matthias Clasen  <maclas@gmx.de>

        * io-bmp.c (DecodeHeader): Replace a g_assert_not_reached ()
        which could actually be reached by a proper error status return.

2002-03-05  Matthias Clasen  <maclas@gmx.de>

        * test-loaders.c, test-images.h: More random tests. 

        * io-bmp.c (DecodeHeader): Fail gracefully on OOM here.

        * Makefile.am (loaderdir): Put the modules into the
        GTK_BINARY_VERSION directory for consistency with
        immodules and theme engines.

Sat Mar  2 22:11:10 2002  Owen Taylor  <otaylor@redhat.com>

        * gdk-pixbuf-io.c (_gdk_pixbuf_load_module): If we
        can't load the module using the g_module_build_path()
        filename, try loading it as a .la file.

        * test-loaders.c: Look for modules in current directory
        rather than .libs, so we find the right .la files.

        * test-loaders.c: Back out some accidental commits.

Sat Mar  2 21:28:03 2002  Owen Taylor  <otaylor@redhat.com>

        * gdk-pixbuf.c (gdk_pixbuf_new): Bullet-proof against integer
        overflow.

2002-03-03  Tor Lillqvist  <tml@iki.fi>

        * gtk-pixbuf.rc.in: Remove.

        * gdk_pixbuf.rc.in: Name like this instead (wrong name used by
        mistake by Hans).

        * makefile.msc: Corresponding changes.

        * Makefile.am: Use gdk_pixbuf.rc on Win32. Distribute it.

2002-02-28  Matthias Clasen  <maclas@gmx.de>

        * pixops/pixops.c (tile_make_weights): Move the call to
        correct_total() to the right spot. (#72732)

        * gdk-pixdata.c (gdk_pixdata_to_csource): Use {} not
        () to group around string assigned to char[]. (#72767,
        Tomas Ögren)

2002-02-21  Havoc Pennington  <hp@pobox.com>

        * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
        C++-commented debug spew, reported by David L. Cooper

2002-02-15  Matthias Clasen  <maclas@gmx.de>

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

2002-02-10  Matthias Clasen  <maclas@gmx.de>

        * test-images.h (tiff1_test_3), test-loaders.c (main): Add a
        (#ifdef 0'ed) test provoking a segfault in TIFFReadDirectory(). 
        
        * io-ico.c (DecodeHeader): Check that pixbuf could be allocated.

        * test-images.h (ico_test_2), test-loaders.c (main): Test the 
        previous change.

        * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment): Don't write 
        beyond the end of buffer if width % 8 != 0.

        * io-tga.c (try_preload): Enforce that ctx->hdr->type is one of
        the supported types, otherwise parse_data_for_row () will not make
        any progress, leading to an infinite loop.

Mon Feb 11 14:31:53 2002  Owen Taylor  <otaylor@redhat.com>

        * pixops/pixops.c (bilinear_make_weights): Fix handing of

        * io-tga.c (try_preload): Detect invalid image dimensions.
        (gdk_pixbuf__tga_stop_load): Don't try to unref NULL pointers.

        * io-ico.c (DecodeHeader): Detect some invalid headers and

Fri Feb  8 23:11:15 2002  Owen Taylor  <otaylor@redhat.com>

        * pixops/pixops.c: Force all weight arrays to sum exactly
        to 65535. (Fixes #70971, reported by Federico Mena Quintero)

        * Makefile.am (libgdk_pixbuf_1_3_la_DEPENDENCIES): Add
        libpixops.la.

2002-02-08  Federico Mena Quintero  <federico@ximian.com>

        assorted G_OBJECT casts where unnecessary.

        * gdk-pixbuf-loader.c: Call g_object_ref and g_object_unref

2001-11-18  Hans Breuer  <hans@breuer.org>

        * io-xbm.c (gdk_pixbuf__xbm_image_begin_load): Use

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

2001-10-05  Sven Neumann  <sven@gimp.org>

        * gdk-pixbuf/gdk-pixbuf-io.c
        * gdk-pixbuf/gdk-pixbuf-private.h
        * gdk-pixbuf/gdk-pixbuf.c
        * gdk-pixbuf/gdk-pixbuf.h
        * gdk-pixbuf/io-jpeg.c
        * gdk-pixbuf/io-png.c: changed GDK_PIXBUF_ERROR_BAD_OPTION_VALUE to
        GDK_PIXBUF_ERROR_BAD_OPTION to we can use it for bad keys too. Added

Thu Sep 20 17:22:48 2001  Owen Taylor  <otaylor@redhat.com>

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

2001-09-20  James Henstridge  <james@daa.com.au>

        * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,
        so that flags types are registered as flags rather than enums (not
        that there are any flags here at the moment).

Wed Sep 19 00:28:24 2001  Owen Taylor  <otaylor@redhat.com>

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

        * Makefile.am: Don't += variables before they have values,
        automake-1.5 doesn't like it.

        * Makefile.am: Fix srcdir != builddir for gdk-pixbuf-enum-types.c.

        * Makefile.am: The whitespace strikes back.
        
2001-09-17  Matt Wilson  <msw@redhat.com>

        * Makefile.am (libpixbufloader_xbm_la_LDFLAGS): removed duplicate
        LDFLAGS definition, use the -avoid-version one.
        (libpixbufloader_tga_la_LDFLAGS): likewise

Mon Sep 17 11:49:02 2001  Owen Taylor  <otaylor@redhat.com>

        * pixops/*: Mirror GdkInterpType to PixopsInterpType
        to avoid including gdk-pixbuf headers.

2001-09-16  James Henstridge  <james@daa.com.au>

        * .cvsignore: add generated files to ignore list.

        out-of-memory situation better.

        * io-pnm.c: Robustness fixes for pnm loader

        * io-gif.c: Make gif loader survive TEST_RANDOMLY_MODIFY

        * io-xpm.c (parse_color): detect very long color strings

        All of the above from Matthias Clasen <matthiasc@poet.de>,
        the remaining from Soeren Sandmann <sandmann@daimi.au.dk>.

        * test-images.h: add tests:
                - four valid ppm's, eight invalid (matthiasc@poet.de)
                - one invalid xpm (matthiasc@poet.de)
                - one valid tga, one invalid (sandmann@daimi.au.dk)
                - one invalid tiff (sandmann@daimi.au.dk

        * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
        fail - detect it when it happens

        * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
        much data in file
        
        * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
        positives
        
Fri Sep 14 00:30:48 2001  Tim Janik  <timj@gtk.org>

        * Makefile.am: don't used BUILT_SOURCES to build marshal
        files, as in conjunction with stamp files, this can
        lead to endless rebuilding loops.

Tue Sep  4 00:22:07 2001  Owen Taylor  <otaylor@redhat.com>

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

Tue Sep  4 03:09:52 2001  Tim Janik  <timj@gtk.org>

        * gdk-pixbuf-csource.1: new file, manual page for
        the publically installed gdk-pixbuf-csource utility.

        io-tga.c: Add tga loader, patch by Nicola Girardi. (#56067)

2001-08-20  Matthias Clasen  <matthiasc@poet.de>

        * test-images.h, test-loaders.c: Add ico and wbmp tests.
        * io-jpeg.c (gdk_pixbuf__jpeg_image_save): Fail with a suitable
        error if buffer allocation fails.
        * io-ico.c: Make .ICO loader more robust.
        All of these are due to sandmann@daimi.au.dk (#50187)

2001-08-19  Sven Neumann  <sven@gimp.org>

        * pixops/pixops.c: applied some simple but effective optimizations 
        to pixops_composite_nearest() and pixops_composite_color_nearest().

2001-08-07  Sven Neumann  <sven@gimp.org>

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

2001-08-06  Kjartan Maraas  <kmaraas@gnome.org>

        * gdk-pixdata.c: Fix a typo.
        
2001-07-30  Hans Breuer  <hans@breuer.org>

        * makefile.msc : use it to complete the build

2001-07-20  Hans Breuer  <hans@breuer.org>

        * gdk-pixdata.c : don't 'g_tohl (*istream++)', but move
        pointer increment out of the macro, because  at least one
        compiler (msvc 5.0) gets confused otherwise (applies the
        wrong increment).

        * gdk_pixbuf.def : updated exports

        * makefile.msc : reflect gdk-pixbuf-csource changes
 
2001-07-17  Darin Adler  <darin@bentspoon.com>

        const.
        * io-wbmp.c: (getin), (get_mbi): Add a missing const.
        * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
        unused locals and add an initial value to quiet the compiler's
        unintialized variable warning.
        * pixops/pixops.c: Put an ifdef around some dead code.

Thu Jul  5 10:17:15 2001  Owen Taylor  <otaylor@redhat.com>

        * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
        over to the new include flags AC_SUBST(). (Problem

        * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf

        instead from gdk_pixbuf_new_from_inline().

        * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
        installed API for applications that need to serialize/deserialize
        on their own (gimp, BEAST).
        
        * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
        program that can dump images in CSource format and Pixbuf
        stream format. supports RLE encoding, MACRO formatting etc...
        invoke with --help.

Mon Jun 25 00:28:11 2001  Owen Taylor  <otaylor@redhat.com>

        * Makefile.am: Actually update timestamps, so rules don't
        constantly run.

2001-06-11  Havoc Pennington  <hp@redhat.com>

        * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
        already includes top_builddir

2001-06-08  Havoc Pennington  <hp@redhat.com>

        * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
        bogus g_return_if_fail  

        * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
        likely timeout resolution, set it to an arbitrarily-chosen short
        delay.
        Fixes bug #55953 from warmenhoven@yahoo.com

2001-06-07  Havoc Pennington  <hp@redhat.com>

        * Makefile.am: use Owen's new way of doing stampfiles/generated
        sources

2001-06-07  Havoc Pennington  <hp@redhat.com>

        * Makefile.am (gdk-pixbuf-marshal.c): fix up the glib-genmarshal path

2001-06-05  Havoc Pennington  <hp@redhat.com>

        * test-loaders.c (main): use putenv not setenv, reported by 
         Armin Theissen

2001-05-08  Havoc Pennington  <hp@redhat.com>

        * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup, 
        and fix behavior to still subst color if the original image 
        had alpha

2001-06-04  Havoc Pennington  <hp@redhat.com>

        * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
        bug #52560

2001-06-01  Havoc Pennington  <hp@redhat.com>

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

        * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
        if it existed
        (png_error_callback): apparently libpng expects you to longjmp out
        of this thing?

        * io-gif.c (struct _GifContext): remove unused "pixbuf" field
        (lzw_read_byte): change "Mail jrb if this fails" g_warning 
        to a g_set_error()
        (gif_get_lzw): check for out-of-memory
        (gif_prepare_lzw): catch/report an error
        (new_context): use try_malloc, since GifContext is nearly 70K
        (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
        so we don't crash later.

        * Makefile.am: Add test-loaders

        * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
        NULL due to errors
        
2001-05-29  Darin Adler  <darin@eazel.com>

        * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".

Mon May 28 14:21:35 2001  Jonathan Blandford  <jrb@redhat.com>

        * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
        fix up bmp decoder to: 
         - adds 16 bpp bmp support (bug #53884)
         - adds OS/2 1.x format bmp support (bug #54964)
         - adds 4 bpp RLE compressed bmp support
         - adds 1 bpp colormap support
         - fixes negative height (top down) bmp support

2001-05-25  Hans Breuer  <hans@breuer.org>

        * gdk_pixbuf.def : reflect Havoc's recent api change

Sun May 20 12:53:49 2001  Owen Taylor  <otaylor@redhat.com>

        * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
        excess $(GLIB_LIBS).

Sun May 13 11:59:11 2001  Owen Taylor  <otaylor@redhat.com>

        * Makefile.am: Make modules depend on libgdk_pixbuf.la.

2001-05-04  Havoc Pennington  <hp@redhat.com>

        * pixops/pixops.c (pixops_process): merge fix from stable: Patch
         from hoshem@mel.comcen.com.au to fix nonzero X offsets.  Fixes
         bug #50371.
        
        * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
        from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
        confusion of using "src" instead of "p".
        (pixops_composite_color_nearest): Use a more accurate (and
        correct, to begin with) compositing method.  This cures checks
        showing through on images with no alpha.

        * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
        bytes unfilled.

        * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints

        * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
        area_updated signal to use signed ints.  Removed animation-related
        signals.

        * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
        rewrite action

        * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
        all the pesky details. Remove old frame-based API. Make
        GdkPixbufAnimation an abstract base class, derived by the loaders.

Sun Apr 22 15:51:32 2001  Owen Taylor  <otaylor@redhat.com>

        * Makefile.am (LDADDS): Add $(MATH_LIB).

2001-04-18  Havoc Pennington  <hp@redhat.com>

        * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
        given color.

Wed Apr  4 01:41:02 2001  Tim Janik  <timj@gtk.org>

        * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
        so we don't try to get <gtk/gtkobject.h> from standard search
        paths.

        * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
        add gdk-pixbuf-marshal.list to EXTRA_DIST.
        take gdk-pixbuf-marshal.h out of _la sources.

2001-03-19  Tor Lillqvist  <tml@iki.fi>

        * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.

        * gdk_pixbuf.def: Update.

        * pixbufloader_*.def: Just export the fill_vtable functions now.

2001-03-18  Mike Kestner  <mkestner@ameritech.net>

        * make-inline-pixbuf.c (main): Added logic to remove output when
        failures occur.

2001-03-14  Havoc Pennington  <hp@redhat.com>

        * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
        from gdk-pixbuf-marshal.h, fixes parallel makes.

Thu Mar  1 04:01:57 2001  Tim Janik  <timj@gtk.org>

        * test-gdk-pixbuf.c: fixed includes.

2001-02-18  Havoc Pennington  <hp@pobox.com>

        * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
        (gdk_pixbuf_get_named_module): prepend underscore
        (gdk_pixbuf_get_module): prepend underscore

2001-02-19  Havoc Pennington  <hp@redhat.com>

        * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix

2001-02-17  Havoc Pennington  <hp@pobox.com>

        * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs

2001-02-07  Alexander Larsson  <alexl@redhat.com>

        * io-xpm.c (free_buffer):
        Use g_free, since the buffer is allocated with g_try_alloc().

2001-02-06  Christophe Merlet  <redfox@eikonex.org>

        * gdk-pixbuf-data.c: Fixes a minor typo.

Sun Feb  4 07:59:57 2001  Tim Janik  <timj@gtk.org>

        * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
        we finally need the gobject->gruntime rename.

        * *.c: scratched calls to g_type_init(), there's simply no point in
        doing that, use gtk_init().

2001-02-01  Havoc Pennington  <hp@pobox.com>

        * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
        in struct to "priv" for C++

2001-01-31  Havoc Pennington  <hp@pobox.com>

        * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h

2001-01-26  Havoc Pennington  <hp@redhat.com>

        * gdk-pixbuf-io.c (mname): fix included modules case.

2001-01-22  Havoc Pennington  <hp@redhat.com>

        * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors 
        from gdk_pixbuf_load_module

2001-01-22  Havoc Pennington  <hp@redhat.com>

        * Makefile.am: Add built marshaller files to support
        GdkPixbufLoader signals

        * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
        GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
        module location, rather than acting as a fallback, because we are
        using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.

        * gdk-pixbuf.h: include gdk-pixbuf-loader.h

        * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
        from gtk, and add error to close(), because stop_load may do
        parsing of the image.
        
        * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file

        * io-*.c: make individual operations static, and add fill_vtable
        functions which are exported. Fix the collection of type warnings
        that surfaced, including a number of functions that didn't
        properly take a GError and some that weren't
        const-correct. Involved adding error handling for a few loaders.

        * gdk-pixbuf-io.h: Add error reporting to stop_load function
        
        * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
        a function that fills in the GdkPixbufModule vtable, instead of 
        looking up all the image functions individually; this means we 
        can get type safety within modules for the loader functions.
        Also it means you don't have to keep the statically compiled and 
        GModule versions in sync. 

        * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()

        * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()

        * gdk-pixbuf.h: nuke gdk_pixbuf_init()
        
        * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
        () here

        * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here

        * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
        g_type_init() here

2001-01-20  John Harper  <jsh@eazel.com>

        * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
        collision between Xlib's RdBitF.c and io-tiff.c

        * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
        io-xbm.c support

        [ merged from stable gdk-pixbuf module. Untested, but it
        compiles, and works fine in the stable module ]

2001-01-18  Tor Lillqvist  <tml@iki.fi>

        * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
        g_win32_get_package_installation_subdirectory() function.  No need
        to include windows.h.
        (gtk_win32_get_installation_directory): Remove this then.

2001-01-01  Havoc Pennington  <hp@redhat.com>

        * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
        @LIBTOOL_EXPORT_OPTIONS@

2000-12-30  Tor Lillqvist  <tml@iki.fi>

        * gdk_pixbuf.def: Update.

2000-12-16  Havoc Pennington  <hp@pobox.com>

        * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
        the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
        (gdk_pixbuf_frame_copy): new function
        (gdk_pixbuf_frame_free): new function
        (gdk_pixbuf_frame_get_type): new function
        (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame

Tue Nov 14 11:51:26 2000  Owen Taylor  <otaylor@redhat.com>

        * Makefile.am: Add -avoid-version for all modules.

2000-11-13  Havoc Pennington  <hp@redhat.com>

        * io-png.c (png_simple_error_callback): fix error message to not
        say "save" since it's used for loading

2000-11-11  Hans Breuer <Hans@Breuer.Org>

        * gdk-pixbuf-io.c : Fix all function prototype macros for self 
        contained image handlers (!USE_G_MODULE). Files to save should
        be opened in binary mode, fopen(s, "wb").

        * io-xpm.c : added HAVE_UNISTD_H condition

2000-11-11  Tor Lillqvist  <tml@iki.fi>

        * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.

        * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
        g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
        mktemp() and open()).
        
        * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.

2000-11-01  Havoc Pennington  <hp@pobox.com>

        * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create 
        a pixbuf pointing to a subregion of another pixbuf.

2000-10-16  Tor Lillqvist  <tml@iki.fi>

        * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).

2000-10-16  Havoc Pennington  <hp@redhat.com>

        * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
        (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module): 
        add error reporting here also

        * make-inline-pixbuf.c (main): use GError

        * io-xpm.c: include unistd.h

        * gdk-pixbuf-util.c: include string.h

        * io-*.c: add error reporting
        
        * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
        error reporting

        * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting

        * gdk-pixbuf-io.h: Add GError** to load_increment and load 
        methods

        * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return 
        a G_FILE_ERROR if we fail to write or close the file.

        * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
        G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
        the GError naming rules. Add GError** to load functions.

2000-10-06  Havoc Pennington  <hp@redhat.com>

        * gdk-pixbuf.h: add GdkPixbufAlphaMode

2000-10-06  Havoc Pennington  <hp@redhat.com>

2000-09-11  Jeffrey Stedfast  <fejj@helixcode.com>

        * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
        last nights code was still "broken". Should now properly handle
        all error conditions gracefully.

2000-09-10  Jeffrey Stedfast  <fejj@helixcode.com>

        * gdk-pixbuf/io-pnm.c: Rewrote.

        g_malloc a malloc.

2000-07-21  Larry Ewing  <lewing@helixcode.com>

        * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
        xpm at least supports the progressive interface like the one in
        io-tiff.c. This should be reimplemented as an actual progressive
        loader.

2000-07-19  Jonathan Blandford  <jrb@redhat.com>

        * demo/pixbuf-demo.c (update_timeout): changed scaling level to
        make it look better.

        gdk-pixbuf module.)

2000-10-03  Tor Lillqvist  <tml@iki.fi>

        * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
        gdk-pixbuf's version number in the rule for makefile.mingw itself.

        * gdk_pixbuf.def: Add new entry points.

2000-09-26  Havoc Pennington  <hp@redhat.com>

        * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
        function here, instead of putting it in a private GTK+ file.

        * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an 
        enum here for the known formats of inlined pixbufs.
        Also, #define our file magic here.

2000-06-23  Havoc Pennington  <hp@redhat.com>

        * make-inline-pixbuf.c: Small program that creates C variable
        declarations of inline pixbuf data. This can be read 
        by gdk_pixbuf_new_from_inline.

        * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
        inline pixbuf data and create a pixbuf from it. 

        * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here

2000-09-07  Tor Lillqvist  <tml@iki.fi>

        * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
        like on Unix.

2000-08-12  Tor Lillqvist  <tml@iki.fi>

        * gdk_pixbuf.def: Add missing entry point.

2000-08-10  Havoc Pennington  <hp@redhat.com>

        * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
        (s/pixbuf_/pixbufloader_)
        
2000-08-02  Tor Lillqvist  <tml@iki.fi>

        * io-bmp.c
        * io-ico.c
        * io-ras.c
        * io-tiff.c
        * io-wbmp.c: Conditionalise inclusion of <unistd.h>.

        * makefile.mingw.in: List loaders alphabetically. Add the wbmp
        one. Fix names of DLLs to have '-' instead of '_'.

2000-07-31  Elliot Lee  <sopwith@redhat.com>
        * io-wbmp.c: Some bug fixes - now tested to work.

2000-07-27  Elliot Lee  <sopwith@redhat.com>

        * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
        gdk_pixbuf_get_named_module() function to facilitate above change
        * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
        Implement loader for WBMP format.
        * io-bmp.c: Don't malloc a temporary buffer - use stack instead.

2000-07-23  Tor Lillqvist  <tml@iki.fi>

        Win32 build setup:
        
        * makefile.mingw.in
        * pixops/makefile.mingw.in
        * pixbuf_*.def: New files.

        * Makefile.am
        * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.

        * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
        New function, to get the GTK+ installation directory from
        the Windows Registry, where the installation program
        for whatever software includes GTK+ has stored it.

        Used to avoid having hardcoding the directory where to look for
        loaders. This function is needed by gtk, too, so it should
        really be just in one place. Maybe a small static library
        one level up from here?

        * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
        * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): 
        Open file in binary mode. This *is* standard C. (No-op on Unix,
        of course.)

        * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().

        * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
        mktemp() and open().
        (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.

        * pixops/*.S: The Gas from mingw32 doesn't like the .type
        pseudo-op. Conditionalise on __MINGW32__, but probably
        should conditionalise on Gas version instead? Or could we
        do without .type on all systems?

        * pixops/timescale.c: Use g_get_current_time()
        instead of gettimeofday().

Sat Jul 22 10:57:22 2000  Owen Taylor  <otaylor@redhat.com>

        * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule

Tue Jul 11 11:26:42 2000  Owen Taylor  <otaylor@redhat.com>

        * gdk-pixbuf.c: Add <string.h> include.

Tue Jul 11 06:20:14 2000  Tim Janik  <timj@gtk.org>

        * io-gif.c (gdk_pixbuf__gif_image_load_animation): 
        * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): 
        * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): 
        use g_object_new() instead of g_type_create_instance() which
        is a private function for fundamental type implementations.
        
Thu Jul  6 11:49:47 2000  Owen Taylor  <otaylor@redhat.com>

        * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
        soname scheme for gdk-pixbuf.
        
2000-06-21  Havoc Pennington  <hp@pobox.com>

        * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
        (i.e. derivation is not allowed, and there are no virtual methods
        anyway).
        (gdk_pixbuf_preinit): Call g_type_init() here.
        (gdk_pixbuf_init): Add a user-friendly init function, for users
        of standalone gdk-pixbuf

        * gdk-pixbuf-animation.c: Convert to GObject, in the same
        way GdkPixbufAnimation was done.
        
        * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
        gdk_pixbuf_finalize() from API, since these are broken and don't
        make sense with new GObject stuff.

Wed Jun 21 16:02:48 2000  Owen Taylor  <otaylor@redhat.com>

        * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
        support a GDK_PIXBUF_MODULEDIR env variable as a secondary
        load location.

2000-06-10  Federico Mena Quintero  <federico@helixcode.com>

        * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
        so I needed something to warm my thighs.  Running plain infinite
        loops on your laptop to make it hot is not very much fun.  A demo
        of the gdk-pixbuf scaling functions is way better, and looks
        prettier, too.

        * configure.in (AC_OUTPUT): Added the demo Makefile.

        * Makefile.am (SUBDIRS): Added the demo directory.

2000-06-09  Larry Ewing  <lewing@helixcode.com>

        * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
        setjmp for the png error handler.  It seems setting the error
        handling functions does not avoid the jump, and so not calling
        setjmp was causing the incremental loader to jump into lala land.
        (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
        not sure this one is actually required but the docs say it must be
        set for every call to a png_* function.
        Also changed the comment to reflect the fact that setting the
        error handlers does _not_ avoid the longjmp.

2000-06-06  Larry Ewing  <lewing@helixcode.com>

        * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
        take frame offest into account when trying to calculate the
        animation bbox.  Also set the width to the width not the height.
        (gdk_pixbuf_loader_animation_done): cycle over the frames to
        calculate bbox because now we finally have all the offset
        information for each frame.

2000-06-05      Mathieu Lacage  <mathieu@gnome.org>

        * configure.in: add some gtk parameters to the
        GDK_PIXBUF_LIBÃ�²S and GDK_PIXBUG_INCLUDEDIR vars. One more
        fight in my crusade for strange prefix compile...

2000-05-30  Not Zed  <NotZed@HelixCode.com>

        * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
        Initialise the error handler exit routine to our own.  Note this
        means that every function that accesses the jpeg lib on this
        object MUST do a setjmp.
        (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
        lib for handling fatal error.
        (gdk_pixbuf__jpeg_image_load_increment): And here too.  So now
        your applications dont quit if there's a jpeg error!

2000-05-30  Federico Mena Quintero  <federico@helixcode.com>

        * gdk-pixbuf.spec.in: Include all the loader libraries.  Patch
        from Frank de Lange <frank@unternet.org>.

2000-05-09  Darin Adler  <darin@eazel.com>

        * gdk-pixbuf/test-gdk-pixbuf.c:
        Fixed includes to get rid of accidental GNOME dependency.

2000-05-26  Cody Russell  <car0969@gamma2.uta.edu>
        * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST

2000-05-22  Federico Mena Quintero  <federico@helixcode.com>

        * configure.in: Bumped version number to 0.8.0.

        * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
        file was not being distributed.

        * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.

2000-05-09  Darin Adler  <darin@eazel.com>

        * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
        (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
        (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
        formats to 32-bit formats to re-use the high bits of the color values
        so that white maps to full white.

Fri May  5 12:16:32 2000  Owen Taylor  <otaylor@redhat.com>

        * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with 
        detailed information about the structure and algorithms
        of pixops so people can fix it instead of breaking it.

2000-05-04  Darin Adler  <darin@eazel.com>

        * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
        (composite_pixel), (composite_line):
        * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
        Now that Owen explained the algorithm, I think I implemented it
        right for the cases where the destination pixbuf is not opaque.
        The test does seem to confirm it.

2000-05-04  Darin Adler  <darin@eazel.com>

        * gdk-pixbuf/.cvsignore:
        * gdk-pixbuf/Makefile.am:
        * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
        (load_pixel), (simple_composite_test_one),
        (simple_composite_test_one_type), (simple_composite_test), (main):
        Added some tests of composite to highlight problems in the old
        implementation. These tests run without any user interaction.
        Just do "make check".

        * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
        (composite_pixel), (composite_line): Fix composite to do a textbook
        "A over B" composite. This was clearly the intent, and it was easy
        to fix the code to do it. (Note to those that read my earlier tries
        at a patch; this version fixes typos that were present in all
        my patch attempts. I checked the final version by adding more tests.)

2000-04-22 05:27:43 2000  Owen Taylor  <otaylor@redhat.com>

        * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
        offset y coordinate accordining to render_y0.

        * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
        dest_x, dest_y.

2000-04-22  James Henstridge  <james@daa.com.au>

        * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
        package to the devel package.  The only file installed in bin is
        gdk-pixbuf-config, which belongs in -devel.  This should allow having
        multiple versions of the main gdk-pixbuf package installed.

2000-04-17  Karl Eichwalder  <ke@suse.de>

        * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
        Reported by Jens Finke.

2000-04-14 Tomasz KÃ�³opczko <kloczek@pld.org.pl>

        * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by 
        $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.

2000-04-13  James Henstridge  <james@daa.com.au>

        * configure.in: when performing the configure check to see if
        gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
        rather than the other way round.  Also, call AC_MSG_RESULT in the
        even that dynamic modules were not supported.

2000-04-12  Federico Mena Quintero  <federico@helixcode.com>

        This comes from an excellent idea by Tim Janik (timj@gtk.org) to
        hook to the last unref operation.

        * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
        function to set the last unref handler for a pixbuf.
        (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
        It calls the pixbuf's destroy notification function and frees the
        GdkPixbuf structure itself.
        (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
        available.

        * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
        for the last unref handler and its user data.

        * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
        g_new0() to allocate the pixbuf.

        * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
        Fixed the call to gtk_signal_new() for the "frame_done" signal; it
        was not specifying the `frame' argument.

        * gdk-pixbuf/gdk-pixbuf-animation.c
        (gdk_pixbuf_animation_get_width): Fixed docstring.
        (gdk_pixbuf_animation_get_height): Likewise.
        (gdk_pixbuf_animation_get_num_frames): Likewise.
        (gdk_pixbuf_animation_get_frames): Likewise.

        * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
        types.

        * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.

        * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.

        * doc/tmpl/refcounting.sgml: Updated with the information about
        the last unref handler.

        * doc/tmpl/*.sgml: Markup tweaks.

        * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
        update the libtool version number for libgnomecanvaspixbuf as
        well.
        (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
        as well, or the old ones won't work with the new stuff.  Also,
        renamed the modules as follows.

        * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
        modules are called "libpixbufloader-<format>.so" instead of
        "libpixbuf-<format>.so".  They needed renaming so that the new
        loaders won't overwrite the old ones; even with the versioning
        stuff, the new .so symlink to the .so.1.0.0 would overwrite the
        old real .so file.

2000-04-12  Paolo Molaro <lupus@debian.org>

        * .cvsignore, src/.cvsignore: shut up cvs.

2000-04-11  Federico Mena Quintero  <federico@helixcode.com>

        Most of this patch is based on a patch by Havoc Pennington
        (hp@redhat.com) to make GdkPixbuf's structures opaque and to
        remove the libart dependency.

        * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
        (GdkColorspace): New enum that for now only contains
        GDK_COLORSPACE_RGB.
        (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
        notification function.
        (GdkInterpType): New num with interpolation types.

        * *.[ch]: Replace the libart stuff with our own stuff.

        * pixops/*.[ch]: Likewise.

        * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
        declarations of the GdkPixbuf structures.

        * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
        Removed function.
        (gdk_pixbuf_get_format): Constify.
        (gdk_pixbuf_get_n_channels): Constify.
        (gdk_pixbuf_get_has_alpha): Constify.
        (gdk_pixbuf_get_bits_per_sample): Constify.
        (gdk_pixbuf_get_pixels): Constify.
        (gdk_pixbuf_get_width): Constify.
        (gdk_pixbuf_get_height): Constify.
        (gdk_pixbuf_get_rowstride): Constify.

        * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
        a pixbuf.

        * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
        bits_per_sample argument; currently only 8 bits per sample are
        supported.

        * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
        New accessor.
        (gdk_pixbuf_frame_get_x_offset): New accessor.
        (gdk_pixbuf_frame_get_y_offset): New accessor.
        (gdk_pixbuf_frame_get_delay_time): New accessor.
        (gdk_pixbuf_frame_get_action): New accessor.

        * gdk-pixbuf/gdk-pixbuf-render.c
        (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
        mask rectangle for pixbufs without an alpha channel, set the
        *mask_return to NULL.

        * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.

        * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.

        * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
        preconditions.  Maybe we should also check for the colorspace,
        bits per pixel, and such.
        (gdk_pixbuf_composite): Likewise.
        (gdk_pixbuf_composite_color): Likewise.
        (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
        cannot allocate the new pixbuf.
        (gdk_pixbuf_composite_color_simple): Likewise.

        * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
        Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
        have an ArtPixBuf.

        * gdk-pixbuf/io-bmp.c: Fix includes.

        * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
        an lvalue.

        * TODO: Populated.

        * configure.in: Removed checks for libart.

        * gdk-pixbuf/Makefile.am: Removed references to libart.
        (noinst_HEADERS): Added gdk-pixbuf-private.h.

        * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
        the version number of the libtool library to indicate that this
        definitely is not compatible with the old usage.  I know you love
        me.  I know you do.

        * configure.in: Bumped version number to 0.7.0.

        * README: Updated.

        * gdk-pixbuf-config.in (--libs): We no longer require libart.

        * DEPENDS.libgdk_pixbuf: We no longer depend on libart.

        * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.

2000-04-06  Jonathan Blandford  <jrb@redhat.com>

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

2000-04-04  Ettore Perazzoli  <ettore@helixcode.com>

        * gdk-pixbuf/gdk-pixbuf-animation.c
        (gdk_pixbuf_animation_get_width): New accessor function.
        (gdk_pixbuf_animation_get_height): New accessor function.
        (gdk_pixbuf_animation_get_num_frames): New accessor function.
        (gdk_pixbuf_animation_get_frames): New accessor function.

2000-04-01  Federico Mena Quintero  <federico@helixcode.com>

        * gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference
        counting to animations.  A web browser may want to share a single
        copy of an animated GIF if it appears multiple times in a web
        page, for example.

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

        * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
        Prettified.  Made ref_count assertion more paranoid.  Check that
        the filename is not NULL.
        (gdk_pixbuf_get_module): Use guchar * and guint for buffer and
        size, respectively.
        (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
        const char **.

        * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
        with a reference count of 1.

        * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
        gdk-pixbuf-animation.c.

        * doc/tmpl/animation.sgml: Populated.  It is still missing a
        description of the overlay modes.

        * doc/gdk-pixbuf-sections.txt: Added the animation section.  Moved
        the canvas item section to the end, as it will be moved later to
        gnome-libs.

        * doc/gdk-pixbuf.sgml: Added the animation section.

        * doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.

1999-12-26  Peter Teichman  <pat@gnu.org>

        * gdk-pixbuf/Makefile.am (libpixbuf_tiff_la_LIBADD): add
        $(LIBTIFF) to libpixbuf_tiff_la_LIBADD, proxying for mmarker.
        This closes bug #4676.

1999-12-23  Havoc Pennington  <hp@pobox.com>

        * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
        set to NULL here (specifically context->animation) was not being
        set to NULL. use g_new0() to alloc the struct.

1999-12-20  Jonathan Blandford  <jrb@redhat.com>

        * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
        correctly.  Progressive loading needs some work, but that all
        needs doing from the gdk-pixbuf-loader end, not here.

1999-12-17  Jonathan Blandford  <jrb@redhat.com>

        * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
        moved the file here.  It seems natural to put this function here,
        as that's where the gdk_pixbuf_new_from_file function is, but it's
        still a little convoluted.  The source files might be played with
        in a bit.

1999-12-14  Jonathan Blandford  <jrb@redhat.com>

        * gdk-pixbuf/gdk-pixbuf-loader.c
        (gdk_pixbuf_loader_get_animation):  Gets the animation from the
        loader.

1999-12-16  Federico Mena Quintero  <federico@redhat.com>

        * doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB
        before using the GdkPixbuf rendering functions.  Thanks to Joe
        Shaw <joe@off.net> for pointing this out.

1999-12-13  Federico Mena Quintero  <federico@redhat.com>

        * gdk-pixbuf/gnome-canvas-pixbuf.c
        (gnome_canvas_pixbuf_class_init): Renamed arguments to
        width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
        consistency with the new canvas.
        (PixbufPrivate): Do the same renaming in the structure fields, for
        consistency.

        * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names.

1999-12-12  Federico Mena Quintero  <federico@redhat.com>

        * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a
        conditional to see whether to link $(GNOME_LIBS) or not.

1999-12-10  Jonathan Blandford  <jrb@redhat.com>

        * gdk-pixbuf/gdk-pixbuf-io.h: thinking about the new loading API.

        * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
        make a warning go away.

        * gdk-pixbuf/gdk-pixbuf.h: added new prototypes for animations.

        * gdk-pixbuf/gdk-pixbuf-loader.h: added new prototypes for
        animations.

1999-12-09  Michael Zucchi  <zucchi@zedzone.mmc.com.au>

        * gdk-pixbuf/gdk-pixbuf.h: Enable gdk_pixbuf_get_from_drawable()
        api call.

        * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
        Filled in body of function.
        (rgbconvert): Added GdkColormap parameter, and to all conversion
        functions also.
        (convert_real_slow): New function - should convert ANY visual/data
        format properly, but it aint fast.  Used as a fallback when an
        optimised routine wont match.
        (rgbconvert): Do very specific tests on the data format to verify
        properly if the optimised version will do, otherwise use the
        fallback function for all other data formats.

        * gdk-pixbuf/Makefile.am: Re-enabled building of
        textpixbuf-drawable.

        * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
        gdk_pixbuf_get_from_drawable().

1999-12-08  Arjan van de Ven <arjan@fenrus.demon.nl>

        * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red
        bug on two occasions.
        * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu
        function to the generic glib one.

1999-12-08  Federico Mena Quintero  <federico@redhat.com>

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

        * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
        gdk_pixbuf_get_from_drawable().  Killed gdk-pixbuf-drawable.h.

        * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.

        * doc/tmpl/from-drawables.sgml: Populated.

        * doc/gdk-pixbuf.sgml: Added the from-drawables section.

        * doc/Makefile.am (tmpl_sources): Added tmpl/from-drawables.sgml.

        * doc/gdk-pixbuf-sections.txt: Added a section for getting pixbufs
        from drawables.

1999-12-07  Federico Mena Quintero  <federico@redhat.com>

        * doc/tmpl/gnome-canvas-pixbuf.sgml: Added clarification about
        reference counting for GdkPixbuf structures.

1999-12-07  Martin Baulig  <martin@home-of-linux.org>

        * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
        include $(GNOME_LIBS) here.

1999-12-05  Arjan van de Ven <arjan@fenrus.demon.nl>

        Added missing "include <string.h>" to:
        * gdk-pixbuf/io-ras.c
        * gdk-pixbuf/io-bmp.c
        * gdk-pixbuf/io-ico.c

1999-12-06  Federico Mena Quintero  <federico@redhat.com>

        * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
        fix an initializer.

1999-12-05  Federico Mena Quintero  <federico@redhat.com>

        * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
        $(GNOME_LIBS).  This must compile outside of gnome-libs.  If you
        want, send me a patch to do the conditional stuff properly.
        Otherwise, please read the GNOME Programming Guidelines,
        especially the "CVS policies" section.

1999-12-05  Jaka Mocnik  <jaka.mocnik@kiss.uni-lj.si>

        * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.

1999-12-05  Arjan van de Ven <arjan@fenrus.demon.nl>

        * gdk-pixbuf/io-ico.c: Bug in palet-size
        calculation fixed

1999-12-04  Arjan van de Ven <arjan@fenrus.demon.nl>

        * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
        32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.

        * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint

        * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
        ran through lclint.

        * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
        (Windows Cursor files). These are identical to .ICO files,
        except for the signature and 2 extra fields for the hotspot.

1999-12-03  Federico Mena Quintero  <federico@redhat.com>

        * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):
        Removed unused variable `item'.

1999-12-03  Jonathan Blandford  <jrb@redhat.com>

        * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to
        explain this function better.

1999-12-02  Federico Mena Quintero  <federico@redhat.com>

        Source files moved from src/ to gdk-pixbuf/, to be consistent with
        other libraries.

        * doc/Makefile.am: Modified for the new source directory.

        * configure.in: Likewise.

        * Makefile.am: Likewise.

        * autogen.sh: Likewise.

        * gdk-pixbuf/Makefile.am: Likewise.

1999-12-02  Federico Mena Quintero  <federico@redhat.com>

        * src/testpixbuf.c: #include <config.h>, and fix includes.

        * src/testpixbuf-drawable.c: #include <config.h>, and fix includes.

        * src/io-xpm.c: Fix includes.

        * src/io-tiff.c: Fix includes.

        * src/io-ras.c: Fix includes, and do not include more stuff than needed.

        * src/io-pnm.c: Fix inlcudes, and do not include more stuff than needed.

        * src/io-png.c: Fix includes.

        * src/io-ico.c: Fix includes, and do not include more stuff than needed.

        * src/io-gif.c: Fix includes, and do not include more stuff than needed.

        * src/io-bmp.c: Fix includes, and do not include more stuff than needed.

        * src/gnome-canvas-pixbuf.c: Fix includes.

        * src/gdk-pixbuf.c: Fix includes.

        * src/gdk-pixbuf-util.c: Fix includes.

        * src/gdk-pixbuf-render.c: Fix includes.

        * src/gdk-pixbuf-io.h: Fix includes.

        * src/gdk-pixbuf-drawable.c: Fix includes.

        * src/gdk-pixbuf-drawable.h: Use angle brackets for the gdk-pixbuf
        include files.

        * src/gdk-pixbuf-data.c: Fix includes.

        * src/gdk-pixbuf-loader.c: #include <config.h>

        * src/gdk-pixbuf-loader.h: Use angle brackets for the gdk-pixbuf
        include files.

        * src/Makefile.am: Commented out the gdk-pixbuf-drawable stuff,
        since it is not finished.

        * src/gdk-pixbuf.h: Removed unused transformation prototypes.

        * src/gdk-pixbuf-util.c: New file with utility and convenience
        functions for pixbufs.

        * src/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-util.c.

        * doc/gdk-pixbuf-sections.txt: Added section for utility functions.

        * doc/Makefile.am (tmpl_sources): Added tmpl/util.sgml.

        * doc/gdk-pixbuf.sgml: Added the utilities section.

        * doc/tmpl/util.sgml: Documentation for the utility functions.

1999-11-29  Owen Taylor  <otaylor@redhat.com>

        * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
        Keep the mask around until after we draw ... since
        the GC changes aren't flushed to the X server until we
        draw, destroying it before that may result in BadPixmap
        errors.

1999-11-30  Havoc Pennington  <hp@pobox.com>

        * configure.in: Add AM_CONDITIONAL for inside gnome-libs

        * src/Makefile.am: conditionalize GnomeCanvasPixbuf

1999-11-29  Federico Mena Quintero  <federico@redhat.com>

        * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources.  This
        should be made conditional, not blindly commented out.

1999-11-29  Jonathan Blandford  <jrb@redhat.com>

        * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
        handle .ico files.  Cool.

1999-11-24  Jonathan Blandford  <jrb@redhat.com>

        * src/io-bmp.c (OneLine24): new patch from Arjan to handle
        compressed bmps.

1999-11-24  James Henstridge  <james@daa.com.au>

        * configure.in (AC_OUTPUT): altered hack to place the symlink in the
        top builddir rather than src.  This still builds fine, and does not
        get gtk-doc into an infinite loop when trying to find all the source
        files.

1999-11-23  Jonathan Blandford  <jrb@redhat.com>

        * Removed #PRAGMA } from headers.  Also, make compile if you don't
        have it installed, already.

1999-11-22  Federico Mena Quintero  <federico@redhat.com>

        * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
        temporary buffer to the size of the interesction of the bounding
        box and the expose area, not the whole expose area.  This speeds
        up things a lot.

        * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
        not paint black on the mask, since we already cleared it in a
        single gdk_draw_rectangle() operation.

1999-11-22  Raja R Harinath  <harinath@cs.umn.edu>

        * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.

1999-11-22  Havoc Pennington  <hp@pobox.com>

        * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
        <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
        dependencies to LIBADD variables for loadable modules. Necessary
        for a Java dynamic loading thing to be able to figure it out.

1999-11-22  Havoc Pennington  <hp@pobox.com>

        * src/io-png.c (image_load_increment): Call the update_area
        callback depending on the number of rows loaded in this increment.

        * src/testpixbuf.c (main): slow down the progressive load demo

1999-11-16  Havoc Pennington  <hp@pobox.com>

        * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include

1999-11-22  Jonathan Blandford  <jrb@redhat.com>

        * configure.in (GDK_PIXBUF_DIR): make the symlink.  Does not work
        for srcdir != buildir != .  Beats me why; I can't figure it out.
        AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.

1999-11-21  Jonathan Blandford  <jrb@redhat.com>

        * src/gdk-pixbuf-io.c: added io-bmp from Arjan
        <arjan@fenrus.demon.nl>

1999-11-20  Michael Zucchi  <zucchi@zedzone.mmc.com.au>

        * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
        Rework/reorder of the code.  Each case has been separated into
        another function; its big but it should be quick.
        gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
        opaque alpha information.  Not all depths/formats have been
        tested, but 8, 15/16 and 24 (alinged 32) should work ok.

1999-11-17  Larry Ewing  <lewing@gimp.org>

        * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
        implement the bounds method correctly.
        (compute_viewport_affine): compute the affine need to fit the
        image within the viewport given by the args.
        (compute_render_affine): call compute_viewport_affine.

1999-11-16  Havoc Pennington  <hp@pobox.com>

        * src/gdk-pixbuf-drawable.h: Use includes from the current
        directory, not the system directory.

Mon Nov 15 17:18:28 1999  George Lebl <jirka@5z.com>

        * src/testpixbuf-drawable.c: use includes from the current directory
          rather then from the system include directory as gdk-pixbuf
          includes are not yet installed when this is compiled.

1999-11-13  Cody Russell  <bratsche@dfw.net>
        * src/testpixbuf-drawable.c: Added a test program for drawable
        code.

        * src/Makefile.am: Build testpixbuf-drawable.

1999-11-12  Cody Russell  <bratsche@dfw.net>

        * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.

1999-11-10  Federico Mena Quintero  <federico@redhat.com>

        * doc/tmpl/gdk-pixbuf-loader.sgml: Populated.

        * doc/gdk-pixbuf.signals: Put in the real names of signal
        arguments.

        * src/gdk-pixbuf-loader.c: Improved documentation comments.

1999-11-10  Jonathan Blandford  <jrb@redhat.com>

        * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
        closed signal.

        * src/io-ras.c (OneLineMapped_file): Now can handle indexing
        correctly.  Patch from Arjan to do so.

1999-11-10  Michael Fulbright  <drmike@redhat.com>

        * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
        files.

        * src/testpixbuf.c: Added final queued draw when done loading image.

1999-11-10  Jonathan Blandford  <jrb@redhat.com>

        * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
        print statements.

1999-11-10  Federico Mena Quintero  <federico@redhat.com>

        * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
        documentation.

1999-11-09  Federico Mena Quintero  <federico@redhat.com>

        * src/io-png.c: Fixed some incompatible pointer initializations.

        * src/io-jpeg.c (image_load_increment): Remove unused variable.

1999-11-09  Michael Fulbright  <drmike@redhat.com>

        * src/testpixbuf.c: Fixed it to use timeout to read from file
        for progressive loading. Set TBF_KBPS=n, where n is the number of
        kilobytes/second to simulate in downloading. n has to be an integer.

        * src/io-jpeg.c: Slight cosmetic cleanup.

        * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
        PBM loading has a similar problem and will address tomorrow.

1999-11-09  Havoc Pennington  <hp@pobox.com>

        * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
        gdk-pixbuf-drawable stuff.

1999-11-09  Federico Mena Quintero  <federico@redhat.com>

        * configure.in: Bumped version number to 0.4.

1999-11-09  Michael Fulbright  <drmike@redhat.com>

        * src/io-pnm.c : Finished progressive PNM loading code. Should handle
        all types of PNM files now.

        * src/io-jpeg.c (image_load_increment): Figured out problem with
        loading Progressive JPEG's progressively (say that 10 times fast).
        Currently for Progressive JPEG's the entire image is loaded before
        it is displayed. libjpeg supports a fancier mechanism which I may
        implement later.

        With these changes all JPEG formats appear to load properly for me.

1999-11-08  Jonathan Blandford  <jrb@redhat.com>

        * src/io-ras.c (image_load_increment): Final patch from Arjan.
        Seems to do progressive loading.

1999-11-08  Michael Fulbright  <drmike@redhat.com>

        * src/io-pnm.c image_load (): Fixed so we do not create a separate
        pixel buffer when reading in image - we reuse the pixel data in
        the GdkPixbuf structure instead.

1999-11-08  Michael Fulbright  <drmike@redhat.com>

        * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
        ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
        I can't seem to find a utility to convert into this format.
        Next is to add progressive loading support for the PNM format.

1999-11-07  Federico Mena Quintero  <federico@redhat.com>

        <arjan@fenrus.demon.nl> to begin the ras loader.

1999-11-05  Federico Mena Quintero  <federico@redhat.com>

        * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is

        * Makefile.am: Added doc to SUBDIRS.

1999-11-04  Michael Fulbright  <drmike@redhat.com>

        * src/io-jpeg.c: Prettied up code slightly.
        * src/io-pnm.c:  Start of pnm loader (from file and progressively).
                         Doesn't do much yet (will finish tomorrow).

        docs, explain what a dither offset is for.
        (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
        this function vs. gdk_pixbuf_render_to_drawable().

1999-11-04  Havoc Pennington  <hp@pobox.com>

        * configure.in: Use libart-config correctly; find gnome-config
        separately. Fix GNOME_LIBS to be correct in "no gnome installed
        yet" case.

        * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
        library list.

        Patch untested in the inside-gnome-libs case, I need to commit
        then check out to the gnome-libs I'm using.

1999-11-04  Michael Fulbright  <drmike@redhat.com>

        documentation comments.

        * doc/: Finished integrating the documentation framework.

1999-11-03  Federico Mena Quintero  <federico@redhat.com>

        * configure.in: Removed libgif stuff now that we do not depend on it.
        Added the necessary cruft for gtk-doc.

        * src/Makefile.am: Unconditionally build the GIF loader.

1999-11-03  Jonathan Blandford  <jrb@redhat.com>

        * src/io-gif.c (gif_read): renamed ReadOK to gif_read.
        Added a lot of comments to the file.

        * src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on
        lib*gif!!!!

1999-11-03  Michael Fulbright  <drmike@redhat.com>

        * src/io-jpeg.c (image_load_increment): Further removal of
        bugginess in local buffering code. Handles grayscale jpegs
        correctly now.

        * src/io-jpeg.c (image_load_stop): Was freeing local context
        for jpeg library before calling jpeg_decompres_finish ().

1999-11-03  Jonathan Blandford  <jrb@redhat.com>

        * src/io-gif.c (image_load_increment): now handle arbitrary buffer
        sizes.
        (gif_get_lzw): set the transparency to the right val.

1999-11-03  Federico Mena Quintero  <federico@redhat.com>

        * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
        Initiailize the x and y fields.
        (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
        (PixbufPrivate): Renamed need_size_update to need_xform_update.
        (recompute_bounding_box): Do not use temporary values.

1999-11-03  Jonathan Blandford  <jrb@redhat.com>

        * src/io-gif.c (set_gif_lzw_clear_code): new state.  Fixes
        un-compressed gifs.

        * src/gnome-canvas-pixbuf.c (recompute_bounding_box): remove
        unneeded x,y,h,w vars.

1999-11-03  Larry Ewing  <lewing@gimp.org>

        * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
        render_affine calculation for x,y offsets.
        (gnome_canvas_pixbuf_set_arg): add x,y args.
        (gnome_canvas_pixbuf_get_arg): add x,y args.
        (recompute_bounding_box): simply code using ArtDrect and the
        render_affine.  Removed compute_xform_vectors as it was no longer
        needed.

1999-11-03  Federico Mena Quintero  <federico@redhat.com>

        * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
        doofus.  Return a distance, not a boolean, for opaque images.

        * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
        rounding of bounding box coordinates.
        (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
        (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.

1999-11-03  Jonathan Blandford  <jrb@redhat.com>

        * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g

1999-11-03  Michael Fulbright  <drmike@redhat.com>

        * src/io-jpg.c (image_load_increment): Fixed code which moved
        buffer around as new data comes in to work properly. JPEG progressive
        loading should be working now except for grayscale JPEG's, which I
        will look into next.

1999-11-03    <sopwith@redhat.com>
        * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
          Also put dot printing back in.

1999-11-03    <jrb@redhat.com>

        * src/io-gif.c (gif_get_extension): Read 'til the next empty block
        correctly, now.

1999-11-02  Cody Russell  <bratsche@dfw.net>
        * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
        if part of the requested image is offscreen, rather than clipping
        the image.

1999-11-02  Jonathan Blandford  <jrb@redhat.com>

        * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
        for interlacing and progressive loading.

1999-11-02  Cody Russell  <bratsche@dfw.net>
        * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
        calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().

1999-11-02  Jonathan Blandford  <jrb@redhat.com>

        * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
        It's a little slow though. )-:

1999-11-02 Elliot Lee <sopwith@redhat.com>
        * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
        write/load_increment operations const-correct.

1999-11-02  Federico Mena Quintero  <federico@redhat.com>

        * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
        Implemented the ::point() method.  We do a simple containment test
        instead of a full distance calculation since the canvas is going
        to change to that scheme, anyways.

1999-11-02 Elliot Lee <sopwith@redhat.com>

        * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
        that are read from the input file.

1999-11-02  Larry Ewing  <lewing@gimp.org>

        * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
        render function.
        (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
        to class.

1999-11-02  Federico Mena Quintero  <federico@redhat.com>

        * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
        affine computation code from ::draw() to here, since it is needed
        by ::point() as well.

1999-11-02 Elliot Lee <sopwith@redhat.com>

        * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
        three functions, and eliminate duplication of code from write()
        and close(). Also fix bug where the 128-byte header was being
        written twice.

1999-11-01  Federico Mena Quintero  <federico@redhat.com>
        * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
        bounding box computation.

1999-11-01  Federico Mena Quintero  <federico@redhat.com>

        * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
        Drawing affines seem to work.  Bounding box is fubared.  ::point()
        is not implemented.  This is a work in progress.

        * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
        sources.

        * configure.in: Sigh.  We need to link in libgnomeui for the
        canvas stuff.  This mess will disappear when gdk-pixbuf gets
        folded into gnome-libs.

1999-10-30  Jonathan Blandford  <jrb@redhat.com>

        * src/io-gif.c: Some more work.  Now it generates a gdk_pixbuf of
        the right size, at a minimum, even if the image is squished and
        the wrong color.
        (ReadImage): lets get the offset right.  This will let transparent
        gifs work.

1999-10-29  Michael Fulbright  <drmike@redhat.com>

        * src/io-jpeg.c: image_load_increment(): Fixed bug when
        image width was not a multiple of 4 - always use the
        gdk_pixbuf rowstride to increment pointers!

1999-10-29  Michael Fulbright  <drmike@redhat.com>

        * src/io-jpeg.c: Added first cut at progressive jpeg loading.
        Currently does not handle either progressive jpeg files (jpeg
        files with multiple scans at different quality settings), but
        I plan on adding this support soon. These are fairly rare in
        my experience, so it shouldn't slow people down too much.
        Grayscale jpegs also don't work but that should be easy to fix.

1999-10-29  Michael Fulbright  <drmike@redhat.com>

        * src/testpixbuf.c: Added title to windows so you can identify
        progressive and file windows.

1999-10-29  Michael Fulbright  <drmike@redhat.com>

        * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
        load the image handler when we determine the image type.

        * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
        previously static function load_image_handler () to
        a public function gdk_pixbuf_load_module (). It is needed in
        gdk-pixbuf-loader.c to load image handler modules.  This function
        is different from gdk_pixbuf_get_module (), which only returns
        a reference to the required handler, because it actually loads
        the handler into memory. Both actions should possibly be combined
        in a convenience function since one w/o the other doesn't seem to
        make much sense.

1999-10-28  Jonathan Blandford  <jrb@redhat.com>

        * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
        0 length buffer.

1999-10-28  Federico Mena Quintero  <federico@redhat.com>

        * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
        function to render a portion of a pixbuf to a drawable.  Ignores
        alpha information and takes in a GC.
        (gdk_pixbuf_render_to_drawable_alpha): New function to render a
        portion of a pixbuf to a drawable.  It automatically creates a GC
        and a clipping mask for alpha pixbufs.

1999-10-28  Jonathan Blandford  <jrb@redhat.com>

        * src/gdk-pixbuf.h: turned convenience macros into convenience
        functions so some error checking could be added.

        * src/io-tiff.c (image_load_increment): started work on the tiff
        non-incremental loader.
        (image_begin_load): Finished the incremental loader.

        * src/io-gif.c (image_load_increment): started work on the gif
        incremental loader.

        * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.

1999-10-27  Federico Mena Quintero  <federico@redhat.com>

        * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
        function to threshold a pixbuf's alpha channel into a bitmap.

        * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
        contemplate future extensions to ArtPixBuf's formats.

        * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().

        * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
        macros to fetch the ArtPixBuf's fields.

1999-10-27  Havoc Pennington  <hp@pobox.com>

        * src/testpixbuf.c (main): Display the progressive load

        * src/io-png.c (setup_png_transformations): Break transformation
        code into separate function
        (png_info_callback): Use setup_png_transformations

1999-10-27  Havoc Pennington  <hp@pobox.com>

        * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
        properly whether the XPM module has already been loaded
        (gdk_pixbuf_new_from_file): Check properly if loader module
        was already loaded (was checking if load symbol was present
        in order to decide whether to re-load; should check module !=
        NULL, then load != NULL)
        (image_handler_load): Check in present working directory,
        makes it easier to debug for now
        (file_formats): This array initializer was seriously on crack,
        was assigning a function pointer to a GModule*

        * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*

1999-10-27  Havoc Pennington  <hp@pobox.com>

        * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_finalize):
        Fix typo that prevented compilation
        (gdk_pixbuf_loader_destroy): ditto

1999-10-27  Federico Mena Quintero  <federico@redhat.com>

        * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
        GdkPixbufLoader, not a GtkObject.
        (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
        (gdk_pixbuf_loader_get_type): Documented.
        (gdk_pixbuf_loader_class_init): Initialize the parent class
        correctly.
        (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
        class destroy function.
        (gdk_pixbuf_loader_new): Documented.
        (gdk_pixbuf_loader_finalize): Call the parent class finalize
        function.
        (gdk_pixbuf_loader_write): Use size_t for count.

1999-10-27  Michael Fulbright  <drmike@redhat.com>

        * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
        logic so we only try to close loader if it wasn't previously closed.

1999-10-27  Michael Fulbright  <drmike@redhat.com>

        * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of
        pixbuf_loader properly initialized.

        * src/testpixbuf.c: Made sure we cleanup pixbuf_loader properly
        when done.

1999-10-26  Jonathan Blandford  <jrb@redhat.com>

        * src/gdk-pixbuf-loader.c: Finished initial cut at the object.

1999-10-26  Havoc Pennington  <hp@pobox.com>

        * src/gdk-pixbuf-loader.h: fix signals

        * src/gdk-pixbuf-io.h: add new vtable fields


1999-10-26  Jonathan Blandford  <jrb@redhat.com>

        * src/gdk-pixbuf-loader.h: New Class.  Beginning of progrssive
        loading.

1999-10-25  Federico Mena Quintero  <federico@redhat.com>

        * configure.in (CFLAGS): Patch from Uwe Koloska
        <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.

1999-10-22  Havoc Pennington  <hp@pobox.com>

        * src/io-xpm.c (mem_buffer): Clean up stupid
        increment-inside-array-dereference thing

        * src/testpixbuf.c: Add XPM data tests.

        * src/io-xpm.c: Make the XPM data buffer const, fix const
        correctness throughout the code.

1999-10-22  Havoc Pennington  <hp@pobox.com>

        * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

1999-10-22  Havoc Pennington  <hp@pobox.com>

        * src/io-xpm.c (image_load_xpm_data): Export this symbol for
        loading an XPM from memory.

        * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): New
        function, loads pixbuf from xpm data
        (image_handler_load): Add g_return_if_fail() to ensure the same
        module isn't loaded twice. Add g_module_symbol() to scan for XPM
        loader function.

1999-10-22  Federico Mena Quintero  <federico@redhat.com>

        * src/io-png.c (image_load): Patch from Kristian Hogsberg
        Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
        buffers; the rows can be read in directly into the main pixel
        buffer.

1999-10-20  Federico Mena Quintero  <federico@redhat.com>

        * src/gdk-pixbuf-io.c (image_handler_load): Free path.

1999-10-20  Federico Mena Quintero  <federico@redhat.com>

        * configure.in: Bumped version number to 0.3.

        * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
        version number for the library.

1999-10-20  Federico Mena Quintero  <federico@redhat.com>

        * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field.  Now
        all memory management of the buffer is done by libart.

        * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
        Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.

        * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
        terms of the libart functions.  Removed the old code.

        * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
        symbols.  Saving will not be implemented in GdkPixbuf.

        * src/io-gif.c: Removed the saving stub.
        (image_load): Fixed memory management to fail gracefully if we run
        out of memory while loading the image.  Close the gif file when we
        are done.  This still needs more error handling for the DGif
        functions.

        * src/io-jpeg.c (image_load): Some robustness fixes.

        * src/io-png.c: Removed the saving stuff.

        * src/*: Reindented to use the GNOME Indentation.  Renamed
        GdkPixBuf to GdkPixbuf, for consistency with the function names
        (and it is also easier to type) :-)

1999-10-18  Havoc Pennington  <hp@pobox.com>

        * configure.in: Use AM_PATH_GLIB instead of glib-config directly

        * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS

1999-10-18  Havoc Pennington  <hp@pobox.com>

        * Makefile.am (SUBDIRS): Remove "macros"

        * configure.in: Don't use GNOME_INIT, handle case where we are
        inside gnome-libs. AM_PATH_GTK for the GIF test

        * src/Makefile.am: Change flags to work without libgnomeui,
        comment out testpixbuf for now

1999-10-18  Federico Mena Quintero  <federico@redhat.com>

        * configure.in: Use $GTK_LIBS as the extra libs when checking for
        libgif/libungif, as they need the X libraries.  Fixes bug #2472.

1999-10-10  Cody Russell  <bratsche@dfw.net>
        * src/gdk-pixbuf-drawable.c: core function now determines whether
        the requested geometry is on screen or not, and if some is not
        then the request is clamped to geometry that is on the screen.

        Changed 'pixbuf' to 'art_pixbuf' in core function.

1999-10-08  Michael Fulbright  <drmike@redhat.com>

        * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

        * src/testpifbuf: Changed test program to display cdrom from rgb data
        if no filename given to test program.

1999-10-07  Cody Russell  <bratsche@dfw.net>
        * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
        them, but I wrote them).

        * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
        compile.

        * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
        libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

        * src/gdk-pixbuf-drawable.c: Added #include "gdk-pixbuf-drawable.h"
        to fix compilation.

        * src/gdk-pixbuf-drawable.[ch]: Changed functions to return
        GdkPixBuf* instead of ArtPixBuf*.

1999-09-22  Michael Meeks  <michael@nuclecu.unam.mx>

        * src/gdk-pixbuf.c (gdk_pixbuf_new): created.
        (gdk_pixbuf_scale): use gdk_pixbuf_new + return a new scaled image.

        * src/gdk-pixbuf.h (struct _GdkPixBuf): Re-organise struct, + add
        GdkPixBufUnrefFunc + gdk_pixbuf_new.

        * src/io-jpeg.c (image_load): clean to use gdk_pixbuf_new.

        * src/io-xpm.c (_pixbuf_create_from_xpm): ditto.

        * src/io-tiff.c (image_load): ditto + fix leak

        * src/io-png.c (image_load): ditto + add more exit points; monitor.png
        crashes this module ( add warning :-)

        * src/io-bmp.c (image_load): ditto.

        * src/io-gif.c (image_load): ditto.

1999-09-18  Michael Meeks  <michael@nuclecu.unam.mx>

        * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
        it doesn't crash scaling with alpha.

1999-09-17  Federico Mena Quintero  <federico@redhat.com>

        * src/io-bmp.c (image_load): Set the initial ref_count to 1.

        * src/io-gif.c (image_load): Likewise.

        * src/io-jpeg.c (image_load): Likewise.

        * src/io-png.c (image_load): Likewise.

        * src/io-tiff.c (image_load): Likewise.

        * src/io-xpm.c (_pixbuf_create_from_xpm): Likewise.

        * src/gdk-pixbuf-io.c (gdk_pixbuf_load_image): Added an assertion
        for the ref_count to be != 0.

        * src/gdk-pixbuf.c (gdk_pixbuf_ref): Be more paranoid with sanity
        checking.
        (gdk_pixbuf_unref): Fix incorrect sanity check and comparison.

1999-08-09  Federico Mena Quintero  <federico@nuclecu.unam.mx>

        * src/io-png.c (image_save): Fixed compiler warnings.  Fixed write
        to unallocated memory (row_ptr), and fixed its type as well.  Take
        into account the ArtPixbuf's rowstride when assigning the row
        pointers.

        * src/gdk-pixbuf.c: Fixup includes.

        * src/gdk-pixbuf-io.c: Likewise.

Sat Jul 31 19:19:47 CEST 1999

        * src/gdk-pixbuf-io.c:
        * src/io-png.c: Fixed two obvious C syntax bugs

1999-07-29  Mark Crichton  <crichton@gimp.org>

        * src/io-png.c (image_save): Added PNG saving function

        * src/gdk-pixbuf-io.c: Changed image_save function format.  Now it's
        image_save(GdkPixBuf *p, FILE *f, ...)


1999-07-26  Michael Zucchi  <mzucchi@denr.sa.gov.au>

        * src/Makefile.am (*_LIB): Only build the relevant loaders which
        require extra libraries if we actually have those libraries.

1999-07-23  Richard Hestilow  <hestgray@ionet.net>

        * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
        * gdk_pixbufConf.sh.in: Added for gnome-config
        * Makefile.am:
        * configure.in: Modified to generate gdk_pixbufConf.sh

1999-07-20  Mark Crichton  <crichton@gimp.org>

        * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation.  Now a bbox
        calculation needs to be done.

1999-07-18  Larry Ewing  <lewing@gimp.org>

        * src/io-xpm.c:
        * src/io-gif.c:
        * src/io-png.c:
        * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
        error cases but one or two in the common case.  There are probably
        a few small ones left.

1999-07-18  Mark Crichton  <crichton@gimp.org>

        * configure.in: removed version.h.

        * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
        improvements.

1999-07-17  Mark Crichton  <crichton@gimp.org>

        * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
        (gdk_pixbuf_rotate): Added pixbuf rotation code.
        (gdk_pixbuf_scale): Changed // comments to /* */

        * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
        function to header.

1999-07-16  Larry Ewing  <lewing@gimp.org>

        * src/testpixbuf.c (expose_func): reverted the expose everything
        changes, I'm not sure why these went in.
        (config_func): bring this up to date with the new pixbuf_scale
        semantics.

        * src/gdk-pixbuf-io.c: added a couple of warnings to the module
        loading code so that poeple can diagnose problems better.

        * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
        no longer allocates a new pixbuf, which make things nicer for the
        rest of the code.  Unfortunately there is still a problem with
        scaling rgba images.

1999-07-16  Mark Crichton  <crichton@gimp.org>

        * src/testpixbuf.c (config_func): ConfigureEvent handler.  This
        calls gdk_pixbuf_scale.  However, something is not working.
        N.B.: current pixmap is now stored in user_data with a key of
        "pixmap"

        * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
        Something is still borked, however.

1999-07-15  Larry Ewing  <lewing@gimp.org>

        * src/io-jpeg.c (image_load): add raph@gimp.org's fix to the jpeg
        indexing routine

        * src/testpixbuf.c (main): fix up the file routines a little so
        that you can load multiple files given the file names

1999-07-14  Larry Ewing  <lewing@gimp.org>

        * src/testpixbuf.c (expose_func): added an almost proper expose
        handler for testpixbuf

1999-07-13  Mark Crichton  <crichton@gimp.org>

        * configure.in: Fixed GIF check.  Replaced " with '
        * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale

1999-07-13  Mark Crichton  <crichton@gimp.org>

        * configure.in: I am a bonehead.  Added gif-lib check.
