<p><P>PROBLEM TO BE SOLVED: To perform composition by forming a clipping channel corresponding to the shape of a group of objects regarding drawing of a duplication group of graphical objects. <P>SOLUTION: A method (1000) of compositing a group of graphical objects (B), the method (1000) forms the group of objects (B) in a temporary buffer (W). For each object (C, D) in the group of objects (B), a corresponding clipping path is provided. A resultant clipping path (Z) defined by a union of the clipping paths is calculated. The group of objects from the temporary buffer (W) is composited to a main buffer (V) through the resultant clipping path (Z). <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
