ABSTRACT:
A method and system for use in phototypesetting. A type font character is scanned and character data representative of the font character is generated. The scan data is encoded in accordance with a first predetermined sequence of steps to have the form of an ordered succession of code words. The stored encoded font data is processed in conjunction with character selection control signals to specify a line-to-be-typeset. The selected character data is decoded in accordance with a second predetermined sequence of steps. The first (encoding) and second (decoding) sequences of steps are related so that the format of the stored encoded data is specifically ordered so that it may be utilized in the decoding process as that data is presented. The decoded selected character data is then converted to video signals for an output cathode ray tube. The decoding sequence may be performed to generate stroke signals for the output cathode ray tube (CRT) of a conventional phototypesetting system during the corresponding strokes in the raster pattern of that output CRT operation. The encoding sequence of steps is adapted so that the decoding sequence may be selectively modified to provide selective scaling of the reproduction of the selected characters.
