Abstract
A system for filling at least one of a plurality of different object based rasterized images includes comparing each pixel position along a raster line with pixel edge intersection data of the plurality of different objects to determine if an edge exists at the pixel position, comparing, in the case no edge exists, a next pixel along the raster line while maintaining a currently displayed pixel fill level, and selecting fill level data for each possible one of the plurality of different objects to be represented at the pixel having an edge. A priority fill level of each of the plurality of different objects is determined based on the selected fill level data and one of the plurality of the different objects having the highest priority fill level data is displayed as the current pixel fill level.
