* 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/.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.)

* gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
$(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
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.
2000-03-27 Owen Taylor <otaylor@redhat.com>
* gdk-pixbuf/pixops/pixops.c: Fix problem with
precendence of >> and & which was keeping composite_color
from working with non-gray images.
Mon Jan 31 12:38:50 2000 Owen Taylor <otaylor@redhat.com>
* gdk-pixbuf/pixops/pixops.c (scale_line): Fix from Peter
Wainwright to fix 4a => 4a scaling.
2000-01-22 Federico Mena Quintero <federico@helixcode.com>
* configure.in: Bumped version number to 0.5.0.
* gdk-pixbuf/pixops/timescale.c (dump_array): Removed unused variable.
(main): Return 0.
* gdk-pixbuf/pixops/pixops.c (pixops_composite_color_nearest): Put
parentheses around + in a shift to remove a compiler warning.
(pixops_process): Likewise.
Patch from Ross Golder <rossigee@bigfoot.com> to create an RPM
specfile:

* Makefile.am (EXTRA_DIST): Added gdk-pixbuf.spec.in
2000-01-05 Owen Taylor <otaylor@redhat.com>
* gdk-pixbuf/pixops/pixops.c: Fixed src_channels/dest_channels
confusion. (Again caught by Tomas Ogren's Purify)
2000-01-05 Owen Taylor <otaylor@redhat.com>
* gdk-pixbuf/pixops/pixops.c (pixops_process): Fix computation of end of run indices.
* gdk-pixbuf/pixops/pixops.c: Fix double increments when dest_channels == 4.
(Pointed out by Tomas Ogren)

* gdk-pixbuf/pixops/README: Added a README with a TODO

to reduce flashing when resizing.
2000-01-05 Owen Taylor <otaylor@redhat.com>
* gdk-pixbuf/pixops/: Directory full of pixel data scaling
code that will eventually migrate into libart.
* configure.in acconfig.h: Add checks for MMX compiler support
* gdk-pixbuf/gdk-pixbuf.h gdk-pixbuf/gdk-pixbuf-scale.c:
Nice wrapper routines for the code in pixops that operate
on pixbufs instead of raw data.
* gdk-pixbuf/testpixbuf-scale: Test program for scaling
routines.
