Abstract

A stand-alone, interactive processor and display system for displaying, performing positioning, sizing, and performing supportive composition functions for newspaper ad layout. Interactive work stations position copy, edit and correct text, adjust style and point sizes, to accomplish accurate composition functions. A Bit Image Memory digitally stores all displayed patterns directly to minimize the response time of the system to operator inputs. An arithmetic unit and character generator are disclosed which produce lines and character which accurately represent the final copy.
