Patent ID: 7616203

Claim:
A method, comprising: identifying a first region from a first frame of animation; identifying a second region from a second frame of animation; and automatically assigning a fill to the second region using a processor, including: overlaying the first frame and the second frame; identifying a merging set of two or more subregions that are included in the second region, wherein the two or more subregions includes an overlapping subregion that overlaps with the first region; computing a geometric area of each of the subregions in the merging set; determining which subregion has a greatest geometric area; selecting, as the assigned fill, a fill of the subregion that has the greatest geometric area; merging the merging set of subregions into the second region; and filling the second region, including the overlapping subregion, with only the assigned fill; and displaying the second region on a display.
