Character font memory and character pattern generator using the character font memory

摘要

A pattern processing apparatus comprises: a first memory which has character pattern data as coordinate array points and stores data indicating whether the coordinate points are the points constructing an outline of a character pattern or not; a second memory which stores absolute coordinate values as a reference point in the case where the coordinate points are not the points constructing the outline of the character pattern and also stores relative coordinate values from the reference point or another outline point or the absolute coordinate values as a reference point in the case where the coordinate points are the points constructing the outline of the character pattern; a reading device for receiving a character code and for reading out the coordiante data corresponding to the character code from the first or second memory on the basis of the character code; and a pattern forming device to form a character pattern corresponding to the character code from the coordiante data. Not only thicknesses of line segments of an outline constructing a character pattern but also stroke shapes of the line segments can be controlled, so that a character pattern can be generated at a high quality.
