ABSTRACT:
Method and apparatus for automatically closing gaps prior to painting a cel in a vector-based computer-aided drawing system. A drawing is processed, as it is entered by a user, to generate a stored planar map containing geometric and topological characteristics of the drawing. The planar map is searched to identify gaps and updated to store synthesized gap-closing vectors for those gaps smaller than a selectable size. The gaps are closed before the painting of the cel, or coloring of the drawing, so as to prevent unintended spill-over of the color into adjacent regions.
