Claim Text:
1. A method of identifying regions in a line drawing to fill with a graphical style, comprising: parsing the line drawing to identify a collection of closed regions present in the line drawing, wherein the line drawing includes a plurality of line segments, and each line segment is associated with one of a plurality of layers of the line drawing; generating a planar graph representation of the collection of closed regions present in the line drawing, wherein the planar graph includes information that indicates a correspondence between each line segment in the line drawing and the associated layer of the line drawing; receiving a selection of a graphical style, a selection of matching criteria, and a selection of a seed region present in the line drawing; identifying one or more regions in the collection of closed regions matching the seed region based on the matching criteria and the planar graph representation; and applying, via a processor, the graphical style to the one or more identified regions.
