Abstract

A character generator and method which requires reduced storage memory space for a character memory by virtue of generating bit fill patterns that fill character borders. The borders are, in turn, generated from partial borders that are local to the starting, ending, and any middle coordinate points of an imaginary baseline roughly drawn along the centerlines of strokes making up the character. As especially applied to Japanese and Chinese character sets, the character generator and method further improve on memory storage savings by separating basic characters from compound characters. The compound characters are then generated in terms of reshaped and repositioned basic characters, thus eliminating the redundancies that would otherwise exist.
