Patent ID: 7978364

Claim:
An image processing apparatus comprising: an input unit adapted to input a rendering job which includes a single fixed object common to respective pages, and a plurality of variable objects which are allocated in front of the fixed object and are independent for respective pages; a designation unit adapted to designate an inclusion region that includes rendering regions respectively for the plurality of rendering objects; a transparent processing unit adapted to generate transparent processed images corresponding to a plurality of transparency attributes by executing transparent processing in correspondence with the plurality of transparency attributes for a region of the fixed object that overlaps the inclusion region; for each page included in the rendering job, a clipping image generation unit adapted to generate a clipping image by clipping a region corresponding to a shape of the variable object from the transparent processed image corresponding to the same transparency attribute as the transparency attribute designated for the variable object; and a generation unit adapted to generate rendering data by blending the clipping image and the fixed object.
