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!

2000-04-11  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/gdk-pixbuf-io.h: Change the order of the update func

* 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.

999-10-29  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.

1999-10-20  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.
