999748e922 Remove the ISO8859-1 restriction from the description of png tEXt
* gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
	restriction from the description of png tEXt parameters.

	* io-png.c (png_text_to_pixbuf_option):
	(gdk_pixbuf__png_image_save): If libpng supports it,
	store and retrieve non-ISO8859-1 text as UTF-8.  (#76172)

71e0ad8d9e Restructured to use gdk_pixbuf_new instead of manually allocating image
* io-png.c (gdk_pixbuf__png_image_load): Restructured to use
	gdk_pixbuf_new instead of manually allocating image storage. This
	gives us a good rowstride and overflow checks.  (#77807)

5c16742258 libpng error handlers must not return to their callers, thus longjmp out.
* io-png.c (png_simple_error_callback): libpng error handlers must
	not return to their callers, thus longjmp out. This prevents
	annoying stderr output from the default error handler.

* io-png.c (setup_png_transformations): Changed signature to
	return success and set a GError parameter, adjusted all callers.

1530c14531 Made sure all the error cases involving jpeg or png load/saves clean
Sat Jan 19 20:49:20 2002  Manish Singh  <yosh@gimp.org>

        * io-jpeg.c, io-png.c: Made sure all the error cases involving
        jpeg or png load/saves clean themselves up properly. Marked some
        variables needed for cleanup volatile so they aren't clobbered by
        setjmp.

	 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.

e0fee22e78 Add built marshaller files to support GdkPixbufLoader signals
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

	* gtk/gtktextiter.c, gtk/gtktextiter.h: add sentence equivalents
	to all the word functions

	* gtk/gtktextview.c (gtk_text_view_start_cursor_blink): return
	before doing anything on NULL layout or if we don't have the focus

	* gtk/testtext.c (fill_example_buffer): "justification"

	* gtk/gtktexttag.h, gtk/gtktexttag.c: change the tag attribute
	to be called "justification" not "justify"

	* demos/gtk-demo/textview.c (create_tags): "justification"

	* gtk/gtktextlayout.c (set_para_values): Handle char-wise wrapping

2000-11-13  Havoc Pennington  <hp@redhat.com>

	* gtk/gtktextdisplay.c (gtk_text_render_state_update): fix bug
	where GC didn't always get updated properly

	* demos/gtk-demo/textview.c (create_tags): Use subattributes
	of fonts instead of setting the entire font

	* gtk/testtext.c (fill_example_buffer): Use "size" instead of
	setting entire font

	* gtk/gtkdialog.c (gtk_dialog_add_button): Fix some warnings

	* gtk/gtktexttag.h, gtk/gtktexttag.c: Explode font_desc into
	a bunch of individually-settable font attributes. You can still
	use the "font" and "font_desc" args, they just set all the font
	attributes at once.

2000-06-09  Larry Ewing  <lewing@helixcode.com>

	* gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
	setjmp for the png error handler.  It seems setting the error
	handling functions does not avoid the jump, and so not calling
	setjmp was causing the incremental loader to jump into lala land.
	(gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
	not sure this one is actually required but the docs say it must be
	set for every call to a png_* function.
	Also changed the comment to reflect the fact that setting the
	error handlers does _not_ avoid the longjmp.

829ed02435 Most of this patch is based on a patch by Havoc Pennington (hp@redhat.com)
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_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_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.

	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.
