2001-05-08  Havoc Pennington  <hp@redhat.com>

	* gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,

	* io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,

2001-06-01  Havoc Pennington  <hp@redhat.com>

        Apply patch from sandmann@daimi.au.dk, with some tweaks.
	Makes things a bit more robust, and adds test-loaders.c 
	which is good for finding further robustness bugs to fix.
	
	* io-tiff.c: Try to work around libtiff suckiness a bit; 
	put a giant thread lock on the whole loader, 
	paranoically check both whether error handlers were called and
	also whether functions return false. Handle case where width or
	height is 0. Various cleanups.

	* io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
	if it existed
	(png_error_callback): apparently libpng expects you to longjmp out
	of this thing?

	* io-gif.c (struct _GifContext): remove unused "pixbuf" field
	(lzw_read_byte): change "Mail jrb if this fails" g_warning 
	to a g_set_error()
	(gif_get_lzw): check for out-of-memory
	(gif_prepare_lzw): catch/report an error
	(new_context): use try_malloc, since GifContext is nearly 70K
	(gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
	so we don't crash later.

	* Makefile.am: Add test-loaders

	* gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
	NULL due to errors

2001-05-29  Darin Adler  <darin@eazel.com>

	* gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".

Mon May 28 14:21:35 2001  Jonathan Blandford  <jrb@redhat.com>

	* io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
	fix up bmp decoder to: 
	 - adds 16 bpp bmp support (bug #53884)
	 - adds OS/2 1.x format bmp support (bug #54964)
	 - adds 4 bpp RLE compressed bmp support
	 - adds 1 bpp colormap support
	 - fixes negative height (top down) bmp support

2001-05-04  Havoc Pennington  <hp@redhat.com>

	* pixops/pixops.c (pixops_process): merge fix from stable: Patch
	 from hoshem@mel.comcen.com.au to fix nonzero X offsets.  Fixes
	 bug #50371.
	
        * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
	from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
	confusion of using "src" instead of "p".
        (pixops_composite_color_nearest): Use a more accurate (and
	correct, to begin with) compositing method.  This cures checks
	showing through on images with no alpha.

	* gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
	bytes unfilled.

	* gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints

	* gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
	area_updated signal to use signed ints.  Removed animation-related
	signals.

	* io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
	rewrite action

	* gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
	all the pesky details. Remove old frame-based API. Make
	GdkPixbufAnimation an abstract base class, derived by the loaders.

Wed Apr  4 01:41:02 2001  Tim Janik  <timj@gtk.org>

	* pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
	so we don't try to get <gtk/gtkobject.h> from standard search
	paths.

	* Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
	add gdk-pixbuf-marshal.list to EXTRA_DIST.

	* gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
	we finally need the gobject->gruntime rename.

	* *.c: scratched calls to g_type_init(), there's simply no point in
	doing that, use gtk_init().

2001-01-22  Havoc Pennington  <hp@redhat.com>

	* Makefile.am: Add built marshaller files to support
	GdkPixbufLoader signals

	* gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
	GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
	module location, rather than acting as a fallback, because we are
	using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.

	* gdk-pixbuf.h: include gdk-pixbuf-loader.h

        * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
	from gtk, and add error to close(), because stop_load may do
	parsing of the image.
	
	* pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file

        * io-*.c: make individual operations static, and add fill_vtable
	functions which are exported. Fix the collection of type warnings
	that surfaced, including a number of functions that didn't
	properly take a GError and some that weren't
	const-correct. Involved adding error handling for a few loaders.

	* gdk-pixbuf-io.h: Add error reporting to stop_load function
	
	* gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
	a function that fills in the GdkPixbufModule vtable, instead of 
	looking up all the image functions individually; this means we 
	can get type safety within modules for the loader functions.
	Also it means you don't have to keep the statically compiled and 
	GModule versions in sync. 

	* test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()

	* make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()

	* gdk-pixbuf.h: nuke gdk_pixbuf_init()
	
	* gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
	() here

	* gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here

	* gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
	g_type_init() here

2001-01-20  John Harper  <jsh@eazel.com>

	* io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
	collision between Xlib's RdBitF.c and io-tiff.c

	* gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
	io-xbm.c support

	[ merged from stable gdk-pixbuf module. Untested, but it
	compiles, and works fine in the stable module ]

	Win32 build setup:
	
	* makefile.mingw.in
	* pixops/makefile.mingw.in
	* pixbuf_*.def: New files.

	* Makefile.am
	* pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.

	* gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
	New function, to get the GTK+ installation directory from
	the Windows Registry, where the installation program
	for whatever software includes GTK+ has stored it.

	Used to avoid having hardcoding the directory where to look for
	loaders. This function is needed by gtk, too, so it should
	really be just in one place. Maybe a small static library
	one level up from here?

	* gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
	* gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): 
	Open file in binary mode. This *is* standard C. (No-op on Unix,
	of course.)

	* io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().

	* io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
	mktemp() and open().
	(gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.

	* pixops/*.S: The Gas from mingw32 doesn't like the .type
	pseudo-op. Conditionalise on __MINGW32__, but probably
	should conditionalise on Gas version instead? Or could we
	do without .type on all systems?

	* pixops/timescale.c: Use g_get_current_time()
	instead of gettimeofday().

	(gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm

	set for every call to a png_* function.
	Also changed the comment to reflect the fact that setting the

	This comes from an excellent idea by Tim Janik (timj@gtk.org) to
	hook to the last unref operation.

	* gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
	function to set the last unref handler for a pixbuf.
	(gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
	It calls the pixbuf's destroy notification function and frees the
	GdkPixbuf structure itself.
	(gdk_pixbuf_unref): Use the last unref function of the pixbuf if
	available.

	* gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
	for the last unref handler and its user data.

	* gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
	g_new0() to allocate the pixbuf.

	* gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
	Fixed the call to gtk_signal_new() for the "frame_done" signal; it
	was not specifying the `frame' argument.

	* gdk-pixbuf/gdk-pixbuf-animation.c
	(gdk_pixbuf_animation_get_width): Fixed docstring.
	(gdk_pixbuf_animation_get_height): Likewise.
	(gdk_pixbuf_animation_get_num_frames): Likewise.
	(gdk_pixbuf_animation_get_frames): Likewise.

	update the libtool version number for libgnomecanvaspixbuf as

	(libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
	as well, or the old ones won't work with the new stuff.  Also,
	renamed the modules as follows.

	* gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
	modules are called "libpixbufloader-<format>.so" instead of
	"libpixbuf-<format>.so".  They needed renaming so that the new
	loaders won't overwrite the old ones; even with the versioning
	stuff, the new .so symlink to the .so.1.0.0 would overwrite the
	old real .so file.

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.

	set to NULL. use g_new0() to alloc the struct.

	* 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.

1999-12-17  Jonathan Blandford  <jrb@redhat.com>

	* 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.
