Claim One:
1. An image processing method for generating a gray level rendered pixel value comprising the steps of: providing a digitized image that has a plurality of pixels with each of the pixels being rendered into a halftoned microdot having a density, the microdot existing within one of a plurality of halftoning planes, wherein the halftoning planes are indicative of an intensity value for the pixels; forming a plurality of tiles from the microdots in accordance with a screen angle and a line ruling from a halftone screen used to converted the pixels into the microdots, wherein each of the tiles comprises a repetitive sequence of microdots; associating each of the microdots within the tiles by a coordinate position as well as the density value; storing the tiles into a buffer having a length and a width; and placing into the buffer an offset determined by the tile geometry, wherein the offset acts as a pointer to read data out offset by a predetermined amount in order to generate the repetitive sequence of microdots; and reading the buffer to retrieve stored image data comprising density value.
