A method for pre-processing a vector image, including: receiving data for a vector image, the vector image data including a list of descriptions of global vector objects that can be rasterized for display at arbitrary levels of resolution; for each local region from among a plurality of local rectangular regions of the vector image, the local rectangular regions being associated with levels of resolution, determining local vector objects that correspond to intersections of global vector objects with such local region; and for each local region from among the plurality of local rectangular regions, storing descriptions of its local vector objects within a computer memory.
