ABSTRACT:
Dither patterns are generated for use in converting a gray-scale image to a bi-level image. The dither patterns simulate halftone screen patterns with arbitrary screen angles. The dither patterns are made up of unit patterns, and have sizes calculated so that the unit patterns match up at the edges of the dither pattern.
