Grab screen image


I’m new to openCL, I would love to know if there is any way to extract the screen image from the GPU before it displays it on screen. I need to find a way to get those pixels and convert it to anaglyph(Red-green).




OpenCL doesn’t support any operations for screen’s image.


Thank you for your answer, do you familiar with a tool that can assist?


Hi, @dudidhn, it depends of platform and graphics api.
