ABSTRACT:
A digital character generator method and system encode characters based on a normalized quad in accordance with coordinates of initial starting points of outlines of the character and variational parameters defining changes in those outlines such as slope and curvature. All characters of all formats are encoded for a maximum point size display. Vertical scaling factors permit character generation at any desired point size display. Horizontal scaling factors are employed both for transforming computations based on the encoded parameters for the normalized quad to a desired point size of display and also to adapt cyclic computations to the stroking density of a display CRT.
