Havoc Pennington 518f32d97e contrib subdir
2000-10-06  Havoc Pennington  <hp@redhat.com>

	* Makefile.am (SRC_SUBDIRS): contrib subdir

	* gdk/gdkpixbuf.h: Move GdkPixbufAlphaMode to gdk-pixbuf library,
	so it can be used in Xlib version

	* demos/testpixbuf.c (update_timeout): error checking from 1.0
	tree

	* gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_get_pixbuf): Sync
	change from 1.0 tree that returns first frame of animation
	if the loaded file is an animation.

        * contrib: add new directory to hold stuff that comes with GTK+
	but isn't really part of GTK+ (for now, gdk-pixbuf-xlib)

	* configure.in: add contrib/*

2000-10-06  Havoc Pennington  <hp@redhat.com>

	* gdk-pixbuf.h: add GdkPixbufAlphaMode

2000-10-06  Havoc Pennington  <hp@redhat.com>

        This entry is a summary of the merged-in changes from 1.0.
	Relevant original ChangeLog entries are spliced in after
	this entry; the files they refer to are from the 1.0
	gdk-pixbuf sources.

	* pixops/pixops.c (pixops_composite_nearest): sync a small fix
	from 1.0

	* io-xpm.c (xpm_seek_string): add fscanf error check from 1.0
	Add progressive loader from 1.0

	* io-tiff.c (gdk_pixbuf__tiff_image_begin_load): mem leak fixes
	from 1.0 tree

	* io-pnm.c: new version from 1.0 tree

	* io-jpeg.c (gdk_pixbuf__jpeg_image_load): sync from 1.0, use
	malloc not g_malloc

	* io-gif.c (lzw_read_byte): sync from 1.0, change a g_error to
	g_warning
	(gif_get_next_step): return 0 here, sync from 1.0

	* gdk-pixbuf-util.c: sync email address change for Cody
	Russell

2000-09-11  Jeffrey Stedfast  <fejj@helixcode.com>

	* gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
	last nights code was still "broken". Should now properly handle
	all error conditions gracefully.

2000-09-10  Jeffrey Stedfast  <fejj@helixcode.com>

	* gdk-pixbuf/io-pnm.c: Rewrote.

2000-09-09  Federico Mena Quintero  <federico@helixcode.com>

	* gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute
	the correct dest offset.

2000-08-25  Federico Mena Quintero  <federico@helixcode.com>

	* gdk-pixbuf/io-xpm.c: #include <unistd.h>

2000-08-05  Larry Ewing  <lewing@helixcode.com>

	* gdk-pixbuf/io-tiff.c: stop leaking context->tempname.

	* gdk-pixbuf/io-xpm.c: same as above.

2000-07-26  Michael Meeks  <michael@helixcode.com>

	* gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
	g_malloc a malloc.

2000-07-21  Larry Ewing  <lewing@helixcode.com>

	* gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
	xpm at least supports the progressive interface like the one in
	io-tiff.c. This should be reimplemented as an actual progressive
	loader.

2000-07-19  Jonathan Blandford  <jrb@redhat.com>

	* demo/pixbuf-demo.c (update_timeout): changed scaling level to
	make it look better.
	* gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
	meeks to handle errors better.
