ABSTRACT:
A method for use in a bit-mapped presentation display system for ascertaining the boundary of an arbitrarily-shaped closed polygon filled with a first color-coded pel pattern and then filling the ascertained polygon with a second color-coded pel pattern. The method steps comprise identifying the first color-coded pattern; determining all unique raster runs of said identified first pattern, and creating a counterpart data representation thereof; and filling in at least a portion of the raster color-coded domain with the second pattern as controlled by the data representation.
