摘要： In order to generate a character main body including a character outline from data in which character shape information is stored as a character outline and generate a character with a design, this method comprises steps of generating the outline of the character main body, setting decoration process contents to be applied to the character main body, operating in such a way that the lower-order bits of the character gradation of the generated outline can be outline end information, setting a decoration position in a character outer fringe on the basis of the outline end information for determining on which side of the main body is located the pixel, on the left or right side, generating character decoration by controlling the gradation value of a pixel in which the flag is set and painting out the character main body excluding the generated character decoration.

摘要： A Bezier curve constituting outline font data represents a curve by four coordinate values of a start point, an end point, and two control points. The curve is represented by two coordinates of the start point and the end point in collinear approximation, and by three coordinates of the start point, an intersecting point of two lines, and the end point in bi-linear approximation. In curve pattern approximation, when 32 curve patterns are prepared, the curve is represented by 5-bit data of two coordinates of the start point and the end point, and a pattern number. By effectively employing these three kinds of processes, it is possible to represent a Bezier curve constituting the outline font data with a reduced data volume.

摘要： A difference of coordinate values stored adjacent to each other is compressed by means of a statistical coding system when reading out outline font data storing coordinate values necessary for drawing a contour of a character in order of drawing the contour in a clockwise or counterclockwise direction and also a category of a line connecting a pair of coordinates simultaneously, followed by compressing the coordinate values of the outline font data. A value of a result of subtracting “A−1” from a difference of coordinate values is determined to be a difference value of coordinates if the difference of coordinate value is equal to or greater than a certain value A, and a code expressing the difference value of “0” is added in front of the codes of difference values that are smaller than the value A in the case of a category of line connecting adjacent coordinates to each other being a straight line.
