ABSTRACT:
A gray scaled data generation device which generates characters and figures of a size which is a fixed number of pixels as gray scaled data, based on outline data which includes outline information which expresses outlines of strokes included in characters and figures and stroke information which shows positions of horizontal and vertical strokes, wherein the gray scaled data generation device has optimizing means for optimizing a position of a stroke, said position being in a coordinate system in which the position is expressed in terms of fine pixels given by dividing every pixel of said size in both a horizontal and a vertical direction, by moving a position of every stroke expressed in the stroke information to a position which satisfies certain criteria related to distances from a border of each pixel; outline generation means for generating outlines in said coordinate system from the outline information, for each stroke which has had its position optimized; and gray scaled data generation means for generating gray scaled data for each pixel unit based on the generated outlines.
