Abstract
Disclosed is a method of rasterizing a page comprising a plurality of graphic objects. The method obtains a plurality of pixel-aligned object edges (302,303) of the graphic objects (203), and determining a pixel generation path (402) for the plurality of graphic objects. The method determines a plurality of crossing locations (420-424) based on the pixel aligned object edges and the pixel generation path, at least one of the crossing locations being a vertical crossing location and at least one other crossing location being a horizontal crossing location, rasterizes the page according to the pixel generation path by updating a fill sequence (620-623) upon encountering said determined crossing locations.
