Re: post processing drawing

I have two layers.
On the bottom layer TV signal will be rendered.
On the upper layer (frame buffer) a GTK application will be rendered (WebKit browser).
To make transparent some area of the upper layer (browser) the area is filled with a certain colour (FF00FF). When this happens i need to make that area transparent, that the TV underneath will be visible.

Are you trying to use some kind of overlay feature of your video hardware?

Are you trying to create "shaped windows?"

What is your application?!
