1. A method for transforming image data from a first representation having first pixels to a second representation having second pixels wherein the first pixels of the first representation do not all map to the second pixels of the second representation on a one-to-one basis, comprising: determining, for each pixel location of the second representation, a corresponding set of at least two pixels in the first representation; determining whether a color distance among the color values of the at least two pixels in the first representation indicates threshold color similarity; if the color distance among the at least two pixels indicates threshold color similarity, setting the color values for the pixel location of the second representation to the color values of one of the at least two pixels in the first representation; and if the color distance does not indicate the threshold color similarity, performing at least one alternative process for setting color values for the pixel location of the second representation.
