Abstract

Laser scanners as used with xerographic machines are capable of producing very well defined horizontal and vertical lines. However, slanted lines are subject to "jaggies" as in the example shown in Figure 1. This is because of the very high content of lines at small angles off perpendicular when the font being generated is slanted, which results in low frequency "jaggies" which can be very visible and objectionable. The source of the difficulty is attempting to produce such slants with a square character matrix.
