ABSTRACT:
A font data generator provides bit map font data free from blurs and thickening in character strokes from data expressing outline segments. The font data generator includes an outline data generating unit for providing pixel data representing the entire outline of a character. A selected outline data generating unit generates, from the pixel data representing the entire outline of a character, pixel data representing only some outline segments. In one embodiment, outline segments are seleced if, when the entire outline is traced counter-clockwise, the segments must be traced in either left or down directions. A filling data generating unit generates, from data expressing the outline segments of a character, pixel data to fill in the area surrounded by the outine segments. A data synthesizing means synthesizes the selected outline pixel data and the filling pixel data to form a character. In another embodiment, instead of generating selected outline data, the generator identifies pixel data that represents more than one outline segment of a character. This pixel data is then synthesized with filling pixel data to form a character.
