ABSTRACT:
A method and apparatus for generating fonts that can be used for digital halftoning comprising: providing a computational element capable of performing digital halftoning algorithms; inputting a digitized version of a continuous toned image into the computational element; dividing the digitized image into a series of macropixel elements, where each macropixel is made up of N micropixels; identifying central feature areas and dispersed micropixel areas within each macropixel; generating an integral number of micropixels to represent dispersed micropixel areas, where the integral number is a fraction of a central feature area total; representing the macropixel with a font generated from the central area feature and a reconstituted dispersed area feature, the reconstituted dispersed area feature employing the fraction to determine density of the dispersed area.
