* 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.

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.

* 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.
2000-01-05 Jonathan Blandford <jrb@redhat.com>
* gdk-pixbuf/gdk-pixbuf-io.h: Change the order of the update func
to make it more compatible with the rest of GTK. Added animation
framework for progressive loading.

system.
* gdk-pixbuf/io-ico.c (image_begin_load): ditto
* gdk-pixbuf/io-png.c (image_begin_load): ditto
* gdk-pixbuf/io-ras.c (image_begin_load): ditto
* gdk-pixbuf/io-jpeg.c (image_begin_load): ditto

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
1999-11-22 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.
1999-10-27 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.

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*
* src/io-png.c: Progressive loading stuff compiles, untested.
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.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.
(image_load): Some memory management fixes.
* src/io-tiff.c (image_load): Ditto.
* src/io-xpm.c (pixbuf_create_from_xpm): Ditto.
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.
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.
io-gif.c, io-png.c: Actually put the licencing terms in the code now...
io-xpm.c: XPM parser baed off of gdk's, but this does something with the
transparent colors.
