Abstract

A workstation performs one or more application programs which generate text rendering commands identifying characters. A font cache stores font bitmaps for a plurality of different fonts and these are used to render characters on a display . New font bitmaps are generated when different fonts are identified in a text rendering command and the new font bitmaps are added to the font cache or replace less used font bitmaps.
