This article describes an underscoring feature of a baseline character generator that can be used to generate a raster image of a page from a memory that contains a coded and ordered representation of the page. The design implements underscoring on a baseline character gener ator which prints in 8 scan directions, and has the ability to print variable height and width characters. The design allows underscore (and/or double underscore) to be associated with each character regardless of which of the 8 print scan orientations are being used. Underscore is considered in two different printing modes: normal and rotated. A normal underscore is an underscore which is perpendicular to the scan direction while a rotated underscore is parallel to, or in the, scan direction.
