PixbufAlphaMode
===================================================================

.. currentmodule:: gi.repository.GdkPixbuf





.. deprecated:: 2.42

   There is no user of GdkPixbufAlphaMode in GdkPixbuf,
     and the Xlib utility functions have been split out to their own
     library, gdk-pixbuf-xlib


.. class:: PixbufAlphaMode
   :no-contents-entry:






Control the alpha channel for drawables.

These values can be passed to gdk_pixbuf_xlib_render_to_drawable_alpha()
in gdk-pixbuf-xlib 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.
