ABSTRACT:
A first forming means forms a first line segment along an edge of a polygon which has been delineated on a picture memory. A second forming means forms a plurality of second line segments along the length of the first line segment. The second line segments are comprised of a plurality of pixels and are generally perpendicular to the direction of the first line segment. The values of the second-line-segment pixels may be found using the values of pixels lying on the first line segment. Alternatively, the values of the second-line-segment pixels may be found by interpolation using the values of pixels adjacent the pixels lying on the first line segment.
