Abstract
A digital typesetter for imaging graphics quality characters of a specified font. The typesetter includes an electronic data processing system which receives first digital data defining the identity, form, size and placement of characters to be typeset; receives second digital data defining the contour of each character to be typeset with respect to a normalized encoding set of first and second coordinates; and produces third digital data defining the character boundaries intersecting a raster (scan) line. This third digital data, for at least a portion of the raster line extending the width of several characters, is temporarily stored in a raster line storage buffer. A character imaging device, connected to the line storage buffer, is provided to image successive raster lines on a print medium. Drive means are also provided for moving the print medium in a direction transverse to the direction of the raster (scan) line.
