ABSTRACT:
A method for improving the quality of raster imaging in which an array of pels is selected having a pattern of filled and unfilled pel positions. In the selected array, an assumed line is determined based on its pel pattern by comparing the pel pattern of the selected array with respect to a plurality of predetermined pel patterns each having a predetermined associated line and angle. When a match is found, the assumed line of the selected array is determined as the associated line of the matched predetermined array. The intensity of the pel at the center of array is selected in accordance with the angle of the line. The line, at the predetermined angle, is positioned to bisect the pel to be enhanced. Intensity is determined by the relative areas of the portions of the bisected pel.
