A method of repeatedly rendering to a page a group of objects represented by edges, by identifying a first occurrence of the group in a display list by an identifier, associating the identifier with a display list representation of the group, using the identifier to determine locations on the page where the group is to be repeated, determining if the display list representation of the group is to be used to repeat the group at the locations, repeating in the display list the occurrence of the display list representation of the group, the repeated display list representations comprising (a) transformations of the starting locations of the edges making up the group, shared by each of the repeated edges, and (b) fill and level information accessed by reference associated with each of the edges.
