Abstract
A method of dealing with self-overlapping objects in a system for creating computerised images, which are made up of objects, by means of a scan line process is described. For each of the overlapping objects (1,2), a number of steps are performed. A first step (702) is to determine a directional border of the object (1). Another step (704) involves determining intersections of the directional border (8 to 10) with a current scan line (7). A further step is to determine, for each pixel within the scan line (7), a count of the number of preceding intersections, wherein the count is incremented for a directional border (8,9) crossing in a first direction and is decremented for a directional border crossing (10,11) in a second direction. Still, a further step (706) is to render each pixel of the object (1) a number of times equal to the count.
