Abstract

A software package is described which resides in a color printing system and which automatically intercepts and colorizes black and white documents (or re-colors color documents, if desired) that are sent to the color printer. The description includes pictorial flow charts and segments of code from an existing implementation in a Pascal-like language, implemented for documents expressed in a high-level page description language (PDL). The functionality of each major process in the software is explained in detail, including as examples the process of capturing and parsing user-specified modifications to the automatic coloring instructions, the process of coloring graphical objects according to their existing fill patterns, the process of coloring text and adding textual features such as dropshadows, and the process of coloring bitmaps.
