Retrieve frame buffer (get a screenshot of whole desktop) from CUDA.

Hi!

I’m trying to figure out if it is possible to retrieve the frame buffer data with CUDA - (a full screenshot of the desktop, not the current application window). I have searched the forums and I know that several people have asked about the same previously, but all of those threads are quite old, so I thought this might have been changed by now?

I find it kind of weird if the GPU don’t have direct read access to the frame buffer.

I use a Jetson TK1 for development if that makes any difference ;p

Thanks!

It’s not possible. Use a graphical API like OpenGL or DirectX instead.
