Possible to intercept application paint and paint to framebuffer instead of desktop?
I am trying to paint a window offscreen into a framebuffer. So I can then access this data (I.E: Save image of application even though it is non existant onscreen. I want to launch notepad and have the machine intercept the window before it paints and redirect it to a framebuffer(offscreen surface). Does anyone know how this can be done?
I was thinking of maybe creating a virtual display device and just run the application on that device. Does anyone have any insight on this?
