- * GdkPixbufAlphaMode:
- * @GDK_PIXBUF_ALPHA_BILEVEL: A bilevel clipping mask (black and white)
- *  will be created and used to draw the image.  Pixels below 0.5 opacity
- *  will be considered fully transparent, and all others will be
- *  considered fully opaque.
- * @GDK_PIXBUF_ALPHA_FULL: For now falls back to #GDK_PIXBUF_ALPHA_BILEVEL.
- *  In the future it will do full alpha compositing.
- * 
- * These values can be passed to
- * gdk_pixbuf_xlib_render_to_drawable_alpha() to control how the alpha
- * channel of an image should be handled.  This function can create a
- * bilevel clipping mask (black and white) and use it while painting
- * the image.  In the future, when the X Window System gets an alpha
- * channel extension, it will be possible to do full alpha
- * compositing onto arbitrary drawables.  For now both cases fall
- * back to a bilevel clipping mask.
