I am doing 2D graphics using graphics.py. I wonder if there is a way I can access the display buffer after all the 2D geometries are drawn and before they show up on display. I need to do a post process on the drawn image. For example, tasks I am planning include anti-aliasing for a smoother transition on the edge and applying a geometry warp map for a correct projection on a curved screen, etc. Can anyone tell me how to access the display buffer? If I have to go down to tkinter Canvas, will it work and how?
