  • Method for reducing pixel density along a plurality of axes of a multiple dimension image representation
    Patent number: 5748856
    Abstract: Techniques are disclosed for depleting raster data to provide for faster printing and also to allow printing of the depleted raster data, with a printed dot size that is larger that would otherwise be utilized with the undepleted raster data, on a pixel grid having the resolution of the undepleted raster data. Also disclosed is a technique for up scaling raster data at a particular resolution (e.g., 300 dpi) is scaled in such a manner that the upscaled raster data includes only printed pixels that correspond one-to-one with the printed pixels of the original data and wherein the relative locations of the printed pixels of the original data are maintained in the up scaled raster data. Further disclosed is a technique for printing a pixel array having a particular resolution with a print element array having print elements disposed for printing at a lesser resolution.
