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_has_alpha): Constify. (gdk_pixbuf_get_bits_per_sample): Constify. (gdk_pixbuf_get_pixels): Constify. (gdk_pixbuf_get_width): 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_delay_time): 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. * TODO: Populated. * configure.in: Removed checks for libart. * gdk-pixbuf/Makefile.am: Removed references to libart. (noinst_HEADERS): Added gdk-pixbuf-private.h. * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented the version number of the libtool library to indicate that this definitely is not compatible with the old usage. I know you love me. I know you do. * configure.in: Bumped version number to 0.7.0. * README: Updated. * gdk-pixbuf-config.in (--libs): We no longer require libart. * DEPENDS.libgdk_pixbuf: We no longer depend on libart. * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.

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.

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.

* </programlisting></informalexample>
*
* Currently only few parameters exist. JPEG images can be saved with a
* "quality" parameter; its value should be in the range [0,100].
* Text chunks can be attached to PNG images by specifying parameters of
* the form "tEXt::key", where key is an ASCII string of length 1-79.
* The values are UTF-8 encoded strings.

* ICO images can be saved in depth 16, 24, or 32, by using the "depth"
* parameter. When the ICO saver is given "x_hot" and "y_hot" parameters,
* it produces a CUR instead of an ICO.
