1. A method for expanding features of an image represented by a plurality of binary pixels at a state transition portion of the image without affecting resolution of the image, a state transition defined by pixels at a first state adjacent to pixels at a second state, the method comprising the steps of: storing a group of pixels representing a portion of the image which overlies said state transition in a first storage; isolating a window in said group of pixels, said window including a pixel formation comprising first and second correctable pixels and pixels surrounding said first and second correctable pixels, said first and second correctable pixels being adjacent to said state transition; for said first correctable pixel, determining a corrected binary pixel state according to a first set of state determination rules, said first set of state determination rules being based on binary states of said pixels in said pixel formation; and for said second correctable pixel, determining a corrected binary pixel state according to a second set of state determination rules, said second set of state determination rules being based on binary states of said pixels in said pixel formation and on said corrected binary pixel state of said first correctable pixel.
