Abstract
A method for interactively viewing a vector image, including indicating a request for a desired portion of a vector image, for display at a specified resolution, determining local rectangular regions of a pre-processed vector image that was generated from the vector image, from among a plurality of local rectangular regions, that are appropriate for generating the desired portion of the vector image therefrom, wherein the pre-processed vector image includes a plurality of local rectangular regions and a plurality of local vector objects, each local vector object being associated with one of the local rectangular regions, requesting at least one rectangular region of the pre-processed vector image from a server computer, receiving local vector objects associated with the requested at least one rectangular region of the pre-processed vector image from the server computer, and generating the desired portion of the vector image using the received local vector objects.
