Abstract
A process of displaying images on output displays, incompatible with the input format, is disclosed. In particular, a process of displaying RGB input on a screen having Red, Green, Blue and White bi-level pixel elements defines a convex hull of the output points and maps the input data into the convex hull. Those values are moved outside the convex hull so that they lie on the surface of the convex hull and the mapped values are halftoned to produce output pixel elements corresponding to an approximation of the input pixels.
