ABSTRACT:
A font storage system for use in a typesetter having an electronically controlled character imaging device. The storage system, which preferably includes a floppy disk, has digital information stored thereon defining each character to be typeset by at least two outlines on a normalized X-Y grid. The digital information defining each character includes (1) digital numbers defining the X and Y coordinates of the initial start points of the outline and (2) digital numbers defining a plurality of straight line vectors extending successively along the character outlines. Each vector has a first digital number representing the X coordinate distance and a second digital number representing the Y coordinate distance from one end of the vector to the other.
