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.
A method for encoding characters in relation to a normalized encoding set of first and second coordinates, wherein a character is defined by at least one outline, with storing of the encoded characters for subsequent generation of desired characters from the corresponding, encoded and stored characters, comprising:
A font storage system for generation of random size characters, said storage system having digital information stored thereon defining each character by at least two outlines on a normalized encoding set of first and second coordinates;
