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.

	* gdk-pixbuf/io-gif.c: finished work to make animated gifs load
	correctly.  Progressive loading needs some work, but that all
	needs doing from the gdk-pixbuf-loader end, not here.

	* gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
	moved the file here.  It seems natural to put this function here,
	as that's where the gdk_pixbuf_new_from_file function is, but it's
	still a little convoluted.  The source files might be played with
	in a bit.

	* gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
	(gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
	checks and API definition.  The body needs filling in and it needs
	to do the Right Thing(tm) for pixmaps plus the given colormap and
	windows and their own colormaps.

	* gdk-pixbuf/gdk-pixbuf.h: Added prototype for

	alpha information and takes in a GC.

	and a clipping mask for alpha pixbufs.

blank pixbuf.

* src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Check all
three progressive load funcs are non-NULL, rather than checking
begin_load three times. Also, check whether begin_load returns
NULL on failure.

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.

6423183a63 Ok minor changes.
Ok minor changes.

No longer make a version.h, and cleaned up some code here and there, and added
a quickie dirty-hack rotation function.  However, it rotates at the origin.
Is this what we want?  Or do we want a rotate w.r.t. the center of the pixbuf?

Anyone.
