Abstract
A method for processing binary image data in preparation for further compression in accordance with a table based upon distances between transitions in successive lines. Advantageously, three lines are considered at one time and the spatial relationship between the transitions in the first and second lines and said second and third lines controls the amount of data compression to be accomplished.
