Abstract: For an area fill technique, a digital image in a digital storage is defined by contour lines (e.g. P6-P7) that have an even number of intersections with each horizontal line in a digital storage; for this purpose, horizontal parts in the contour line are ignored, as well as the start points of contour line segments (e.g.P5) that are generated from vector data. Furthermore picture elements (pixels) of contour lines are written by an exclusive OR operation into their corresponding storage location. The area fill operation proceeds then line by line to start writing in filling characters at an odd pixel and ending at the next even pixel. Filling is preferrably performed by exclusive-ORing adjacent storage locations during the line scanning process.
