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