Abstract
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.
