Abstract
For page data containing shadow-casting objects, trap graphics are generated according to the following procedure. First, an ID drawing process is performed for all objects within a page, and based on the process result, a related graphic list indicating relative positional relationships between the objects is generated. Thereafter, an ID drawing process is performed for all objects in the area of each shadow-casting object, excluding the shadow-casting object. The result of the ID drawing process in the shadow-casting object area is reflected in the related graphic list, and thereafter, trap graphics are generated based on settings information in the related graphic list.
