Abstract: A method of synthesizing multi-level raster shapes directly from outlines describing ideal shapes is disclosed. A raster shape suitable for approximating the ideal shape in a raster display device is synthesized by dividing a plane into a plurality of pixel areas according to a pixel grid, then by representing the shape as one or more arcs in the plane, where the arcs collectively, and in conjunction with an insideness criterium, divide the plane into an inside region and an outside region, and then by separating the pixels into inside pixels, outside pixels, and boundary pixels. The raster shape comprises coverage values assigned to each pixel in the plane, where inside pixels are assigned a coverage value of 1, outside pixels a coverage value of 0 and the boundary pixels a coverage value between 0 and 1 approximating the degree to which the boundary pixel is covered by the inside of the outline.
