Re: gdk pixbuf animation

[Cody Russell <bratsche dfw net>]

You'll have to manually add each frame from the animation at this point.
The next major gnome-libs release will support adding frames from a
GdkPixbufAnimation, but gnome-libs 1.0.x does not.

Try something to this effect:


{
   GdkPixbufAnimation *a_pixbuf;
   GtkWidget *animator;

   a_pixbuf = gdk_pixbuf_animation_new_from_file(filename);
   if(a_pixbuf)
   {
      GList *list;
      GdkPixmap *pixmap;
      GdkBitmap *mask;
      GdkImlibImage *im;

      for(list = a_pixbuf->frames; list; list = list->next)
      {
         /* This sort of sucks, but I can't think of a better way to
          * convert from a pixbuf into something GnomeAnimator 1.0 will
          * recognize.
          */
         gdk_pixbuf_render_pixmap_and_mask(((GdkPixbufFrame *)list->data)->pixbuf,
                                           &pixmap, &mask, 0);
         im = gdk_imlib_create_image_from_drawable(pixmap, mask,
                                                   0, 0,
                                                   w, h);
         gnome_animator_append_frame_from_imlib(animator, im, 0, 0,
                                                ((GdkPixbufFrame *)list->data)->delay_time;
      }
   }
}

This isn't working code or anything, but you get the idea.  I've added
GdkPixbuf frame loading for gnome-libs 2.0, and it'll also have
GdkPixbufAnimation file loading as well.  But in the mean time, this hack
shouldn't be too bad.

Happy hacking,
   Cody
