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.

README 

This package contains the reference documentation
for GTK+. For more information about GTK+
see:

 http://www.gtk.org

For information about contributing to the
GLib/GTK+ reference documentation project, see:

 http://www.gtk.org/rdp/

The GTK+ reference documentation is freely redistributable,
see the file COPYING for details.


REQUIREMENTS
============

To build the documentation, you must have the gtk-doc
package installed. To rebuild the template files,
you must have the current version of the GTK+
header files installed.


BUILD
=====

First, run configure to generate the makefiles for this
module. There is one option specific to this package

  --with-html-dir=DIR   top of installed HTML documentation tree


The Makefiles in the gdk/ and gtk/ subdirs each define three targets:

 templates:
  
  Scan the headers and merge the results with the current 
  template files

 sgml:

  Generate SGML files using the DocBook DTD from
  the template files

 html:

  Generate HTML from the SGML files.

To build the documentation, do:

 make sgml
 make html

You should only run the 'make templates' step if you
need to regenerate the templates for a more recent
version of the GTK+ sources.

INSTALLATION
============

 make install
