ABSTRACT:
A system for displaying, performing positioning, sizing, and performing supportive composition functions for newspaper advertising layout in which characters and symbols are displayed with a height and width closely approximating the height and width of the actual printed characters. Characters are displayed as rows and columns of dots. Preselected rows and columns are deleted or repeated to decrease or increase the size of a character from a standard fixed size. 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 including the character dot patterns directly to minimize the response time of the system to operator inputs. An arithmetic unit is disclosed which produces lines which also accurately represent the final copy.
