<P>PROBLEM TO BE SOLVED: To improve raster image development processing efficiency in every page by enabling to reuse raster images already developed in storage means in image development processing for similar kinds of objects even when intermediate page description language data is complex. <P>SOLUTION: When a CPU 1 determines that the similar kinds of objects are included in the intermediate page description language data stored in a RAM 2, identification information is added to the objects and stored in the RAM 2, and the registered objects are developed in a raster image and registered onto the RAM 2. In page development processing, the registered identification information and identification information of the objects to be net developed are compared, and page development processing is performed using the developed raster image. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
