Abstract

A clipping processor capable of setting a clipping area, which has a shape not restricted to a rectangle and is defined in the processing of transferring data on a part of a clipping area in each raster by computing data defining the clipping area by two function generation circuits or by reading the data defining the clipping area from the clipping area memory, in which data defining a part of the clipping area in each raster is preliminarily stored, every time the raster is updated.
