ABSTRACT:
A window clipping method and device for processing data with arbitrarily shaped clipping windows, wherein arbitrarily shaped clipping windows and graphic data are stored in separate bit mapped memories, employing a graphic processor and a controller. The drawing graph is drawn only inside the clipping window, and patterns of the clipping window can also be mixed with the graph. Intersection calculations of the drawing graph and the boundary of the clipping window are not employed.
