摘要: A graphic display system capable of cutting out a partial image according to the invention includes storage means, outline drawing means for an be cut out, mask data generator generating outline, and write writing into only portion source which is not masked by data. The all point addressable (APA) memory in area storing image, work dot pattern representing destination areas are allocated. generates data, whereby region enclosed with put non-masked state, while rest state. may predetermined combining them.
