i am writing an application, which captures every 100ms desktop, and then shows in a small window. (like windows zoom) With + and - you can zoom in or out it. I want to get the pixel data from screendc (after some zooms) and save it to an array.(i will change pixels and draw it again). I tried to get it with twice calling of GetDIBits, but didn t get succeed.
Has anyone read pixels in an array from a screendc?
