ABSTRACT:
Systems and methods for generating visual representations of graphical data and digital document processing, including:A method of redrawing a visual display of graphical data whereby a current display is replaced by an updated display, comprising, in response to a redraw request, immediately replacing the current display with a first approximate representation of the updated display, generating a final updated display, and replacing the approximate representation with the final updated display.A method of generating variable visual representations of graphical data, comprising dividing said graphical data into a plurality of bitmap tiles of fixed, predetermined size, storing said tiles in an indexed array and assembling a required visual representation of said graphical data from a selected set of said tiles.A method of processing a digital document, said document comprising a plurality of graphical objects arranged on at least one page, comprising dividing said document into a plurality of zones and, for each zone, generating a list of objects contained within and overlapping said zone.Digital document processing systems adapted to implement the methods.
