Abstract
A data compressing device for preparing compressed outline data from normal outline data representative of an outline of a character which consists of a plurality of segments connected end to end so as to form a closed loop. The normal outline data includes coordinate data representative of X and Y coordinate of segment specifying points which determine positions of the segments, and segment type data indicative of a type of each segments. The device is adapted to determine whether or not all of a plurality of successive points of the segment specifying points which successive points are successively located along the closed loop have a same X or Y coordinate, and omits the X or Y coordinate for at least one of those successive points, to thereby prepare the compressed outline data, if all of the successive points have the same X or Y coordinate which is equal to the X or Y coordinate to be omitted. Also disclosed is a device adapted to convert the compressed outline data into the normal outline data, by restoring the X and Y coordinates omitted in the compressed outline data.
