11056f564b Welcome aboard, gdk-pixbuf.
Wed Jun 21 16:38:13 2000  Owen Taylor  <otaylor@redhat.com>

        * gdk-pixbuf/* docs/reference/gdk-pixbuf/*: Welcome aboard,
	gdk-pixbuf.

	* gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
	fixups for GObject.

	* gdk/Makefile.am gdk/gdkpixbuf-render.[ch] gdk/gdkpixbuf.[ch]: Bits of
	gdk-pixbuf with GDK dependencies moved into GDK.

	* gtk/Makefile.am gtk/gdk-pixbuf-loader.[ch]: Temporarily
	move gdk-pixbuf-loader here until GObject has signals.

	* demos/: New directory of demos. Move demos from
	gdk-pixbuf here.

	* demos/pixbuf-init.c: Small bit of code to check for
	loaders in ../gdk-pixbuf/.libs/gdk-pixbuf, and if found,
	set GDK_PIXBUF_MODULEDIR appropriately.

	* gdk/gdkcompat.h: Remove GDK_DRAWABLE_PIXMAP compat
	define which no longer makes sense.

* 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.

	* 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.)

	* 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.

2000-04-11  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.

	* gdk-pixbuf/pixops/pixops.c: Fix problem with

	from working with non-gray images.
