Abstract
A method for generating a binary representation of an image represented in half-tone form is described in which the image is scanned and sampled, and in which each pixel corresponding to a sample of the image is assigned one of two colors. The method comprises, for each group of abutting and non-overlapping sampled pixels, determining the number of pixels in the group which are to be assigned to each of the two colors (step 13); allocating a unique sequence to the pixels (step 15); and assigning one of the two colors to pixels in sequential order until the predetermined number of pixels of that color has been assigned (step 16) and thereafter assigning the other color to the remaining pixels in the group (step 17).
