Embodiments of the present invention include a method for generating
a halftone image. This method comprises the steps of choosing a set of allowed
colors, processing a color value, quantizing color value, and outputting a halftone
pixel according to quantizing step. In one embodiment, a look up table is utilized
to provide significant speedup over conventional implementations, especially in
when implemented in software. The result is high quality imaging with excellent
color smoothness and sharpness.
