Abstract
Provided is a method for converting an input vector outline image to an output monochrome raster image consisting of only corner-contiguous pixels in a checkerboard pattern. Using a combination of a monochrome checkerboard raster image and a vector-based diamond grid, a determination is made as to which output raster pixels are activated. Efficiencies in file size and computational complexity are realized by using a checkerboard pattern and only half the possible number of raster output pixels. The method improves monitor and printer raster displays for any personal computing or related device, reducing the need for anti-aliasing and font hinting.
