ABSTRACT:
There is described method and apparatus for use in phototypesetting operations wherein a character is scanned by a plurality of scans or strokes of a light spot output of a cathode ray tube (CRT) of the phototypesetting apparatus, and output signals derived from a photosensor device in response to the light spot, are compacted to be stored in a magnetic storage device. In particular, each stroke is examined to determine which method of a plurality of compacting methods will produce the smallest quantity of image data, thus requiring the minimum storage area within the storage device.
