<P>PROBLEM TO BE SOLVED: To perform color processing classified by object attribute at high speed by using a small quantity of memory, and to output the result on a printer device. <P>SOLUTION: A multivalued bitmap is generated following a drawing instruction (S3), and an attribute bitplane having a plane for drawing area determination corresponding to the attribute of an object included in the multivalued bitmap and having a flag bit set on an address corresponding to a coordinate value where the object of the multivalued bitmap of the plane exists is generated. Each attribute bitplane is scanned, and multivalued data corresponding to the multivalued bitmap are stored in an address of the attribute bitplane where the flag bit is set, and the color processing is performed to the stored multivalued data, and each attribute bitplane corresponding to each object subjected to the color processing is composed and transferred to a printer device. <P>COPYRIGHT: (C)2003,JPO |
