摘要： PROBLEM TO BE SOLVED: To reduce a size of outline font data by approximating a part of a Bezier curve constituting the outline font data in such level that persons cannot recognize difference of design. SOLUTION: With respect to the Bezier curve, one curve is expressed with coordinate values of four points in total of a start point, an end point, and another two control points. The curve can be expressed with coordinates of two points of the start point and the end point by linear approximation and be expressed with coordinates of three points of the start point, an intersection of two lines, and the end point by bilinear approximation. When 32 curve patterns are prepared for curve pattern approximation, the curve patterns can be expressed with 5-bit data as coordinates of two points of the start point and the end point and pattern numbers, and the Bezier curve can be expressed with a small data amount by effectively using three processes.

摘要： PROBLEM TO BE SOLVED: To provide a character generation processing method which is high in speed of modification character generation processing, is small in memory use size and font size required for a character pattern development region and enables character expression having designability assuring character quality. SOLUTION: The outline font data corresponding to character codes is read for every one character (S1), and the low-order bits of the gradation value relating to the outline font data are operated to compute the end information of a contour (S2).

A main body portion of the character and a contour portion bordered by the flag for modification are simultaneously generated for every one line (S4). Finally, painting-out processing is performed to generate the modification character (S5). COPYRIGHT: (C)2007,JPO&INPIT
