ABSTRACT:
A character pattern generating method and apparatus which enables storage of a large amount of font data with a small memory capacity and increase pattern-bitmapping speed. The apparatus stores element information representing common elements for constructing patterns and construction information indicating the construction of each pattern in a font data memory such as a ROM. The sets of element information corresponding to a specified pattern are developed into bitmap data in an element bitmap area. The bitmapped data are synthesized in accordance with construction information for the pattern to be generated.
