Abstract

A processor controlled character box display is provided with apparatus which permits the display of curvilinear graphics. The characters used to generate the graphics display are selected from a limited character set in read only storage (46), but by shifting the characters up or down by less than a full line index to provide additional character positions, it is possible to produce curvilinear graphics without the need for further character generation. Since the graphics display is a low resolution display, it is necessary to make a best dot selection in order to map the print bit map into the character box display.
