If you just want rendering functions which support translucency, use Cairo (you can use XRender directly, but there's unlikely to be any advantage to doing so). The core X protocol doesn't support alpha blending; apart from anything else, it's only meaningful with StaticGray and TrueColor visuals. -- Glynn Clements <gl...@gclements.plus.com> _______________________________________________ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
