Image Number 10 for United States Patent #6956584.
An image processing method converts line vectors of an input graphic path and an input clip path into run sets in dot coordinates passed by the line vectors, and generates a region run describing a closed region represented by the entire path from the run sets, so as to obtain a graphic region run and a clip region run, and extracts an overlapping portion of the graphic region run and the clip region run to generate a plot region run. The scan line conversion and the clipping form a rasterizing process.
