Subject: nvidia: how to use overlay
Date: Thu, 20 Jan 2005 04:18:19 -0800 [thread overview]
Message-ID: <E1CrbGV-0000Lj-Mi@sc8-pr-web1.sourceforge.net> (raw)
gongpu (gongp03@hotmail.com) has submitted this feedback
for nvidia
In my project which I\'m working on, I want to display two layer. One is for some video information. The other is for some symbols. I know how to use frame buffer to write directly to the video ram. But how to implement these two layers?
SDL sdk gives some overlay functions, but I think it was implemented in software. How to use hardware overlay?
Of course, I\'m sure that my video card surpport this kind of overlay.
I\'ll be very appreciated if you can tell me how to do it or where I can find relative information. Thanks for reading. Waiting for your answer.
