Method and apparatus for expanding point matrix characters. For each member of a character set there is stored a basic character matrix defining the character in its lowest magnification. A shape code is assigned to each point of the basic character matrix based upon the configuration of blacks and whites in a neighborhood centering on the point. Quantized versions of the shape codes are used as templates for assigning expanded point arrays to each point in the basic matrix. The method is advantageously implemented by logic circuitry for a matrix printer or the like. The user may vary the aspect ratio of the expanded characters, and may design the shape codes to produce a pleasing character appearance. |
