Your eyes are bloodshot. Your mouth starts to foam. Your hands are shaking. You know your need your fix. NEED MORE ABSTRACTION! 2000-04-12 Federico Mena Quintero <federico@helixcode.com> 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. * doc/gdk-pixbuf-sections.txt: Updated with the new functions and types. * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace. * doc/tmpl/scaling.sgml: Added the description for GdkInterpType. * doc/tmpl/refcounting.sgml: Updated with the information about the last unref handler. * doc/tmpl/*.sgml: Markup tweaks. * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh, update the libtool version number for libgnomecanvaspixbuf as well. (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.

These functions provide miscellaneous utilities for manipulating
|
|
pixbufs. The pixel data in pixbufs may of course be manipulated
|
|
directly by applications, but several common operations can be
|
|
performed by these functions instead.
