	* 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

b4e4a0ed9d fix some shell typos
2001-05-04  Havoc Pennington  <hp@redhat.com>

	* configure.in: fix some shell typos

	* gtk/gtkcolorsel.c (gtk_color_selection_destroy): warning fix

	* gtk/gtkimage.c: handle animations

	* gtk/gtkcheckbutton.c (gtk_check_button_size_request): request
	border_width * 2, not just border_width

	* gtk/gtkscale.c: add "format_value" signal to allow people
	to override the way values are drawn.
	(gtk_scale_get_value_size): fix width/height mistake,
	and compute size from actual displayed text, not
	from made-up text.

	* gtk/gtktexttag.c (gtk_text_tag_class_init): fix return type in
	signal registration

	* tests/testtext.c: Add "Remove all tags" menu item for testing

	* gtk/gtktextbuffer.c (gtk_text_buffer_remove_all_tags): implement

	* demos/gtk-demo/main.c (main): add hack so we can find modules
	without installing gtk

	* demos/gtk-demo/textview.c (insert_text): demo font scaling

	* gtk/gtkcellrenderertext.c: Add "scale" property (font scaling
	factor)
	(gtk_cell_renderer_text_set_property): remove some bogus
	g_object_notify

	* gtk/gtktexttag.c: add "scale" property which is a font scaling
	factor

	* gtk/gtktextlayout.c (add_text_attrs): add font scale attribute
	to layout

	* gtk/gtktextiter.c (gtk_text_iter_is_start): rename from

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.

e0fee22e78 Add built marshaller files to support GdkPixbufLoader signals
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

	* demos/testpixbuf.c: fix to reflect gdk-pixbuf changes

	* gtk/gdk-pixbuf-loader.c, gtk/gdk-pixbuf-loader.h:
	Remove, move back to gdk-pixbuf

	* gtk/gtktextiter.c, gtk/gtktextiter.h: add sentence equivalents
	to all the word functions

	* gtk/gtktextview.c (gtk_text_view_start_cursor_blink): return
	before doing anything on NULL layout or if we don't have the focus

	* gtk/testtext.c (fill_example_buffer): "justification"

	* gtk/gtktexttag.h, gtk/gtktexttag.c: change the tag attribute
	to be called "justification" not "justify"

	* demos/gtk-demo/textview.c (create_tags): "justification"

	* gtk/gtktextlayout.c (set_para_values): Handle char-wise wrapping

	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.

2000-06-21  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.

829ed02435 Most of this patch is based on a patch by Havoc Pennington (hp@redhat.com)
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_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.

	* 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.

2000-01-01  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.

	gifs work.


Right now, gifs with transparency, both interlaced and non-interlaced,
seem to work perfectly fine.  I haven't tried grayscale gifs yet, and I
seem to be getting offset in my RGB buffer with non-alpha gifs. )-:
This leads to pretty, but incorrect, images.
