<p>A video display system is disclosed for use in fitting advertising copy or other text matter in a desired final layout prior to typesetting. The original text is read into a video display terminal from a tape reader, for display on a CRT screen. Changes in the size, location and other parameters of the displayed text are made by typing characters and instructions from a keyboard and control panel at the terminal. The layout instructions and text data are encoded in digital format, modified by computer processing programs in accordance with the layout instructions, and the modified data drives character generating and position logic units for displaying the updated layout on the screen. The layout instructions, in the form of parameter messages, are displayed in an area or field adjacent to the text on the screen. Changes in any portion of the text are initiated by directing a test cursor or a parameter cursor to the appropriate element of text or the associated parameter message to be changed in the display, followed by keyboarding or keying in the desired changes. Following copy layout, the text and associated layout instructions are processed by the system into a format suitable for directly driving a photocomposing machine, and outputted to paper tape, magnetic tape or an electrical connection to a computer system.</p> |
