US 6,583,789 B1 · Method and system for processing glyph-based quality variability requests

Abstract

A user of a data processing system may specify variability in the generation of data for data-presentation, either by displaying or printing, on an output device. The variability specification may be applied on a glyph-by-glyph basis to the presentation of glyphs. The data processing system provides processing of glyph-based quality variability requests in the following manner. The system receives a request for data-presentation of a series of glyphs and determines, for each glyph in the series of glyphs, whether quality variability is applicable to each glyph. If quality variability is applicable to each glyph, then the system determines a quality variance to be applied to each glyph according to predetermined data-presentation variability data and performs data-presentation of each glyph on an output device in accordance with the quality variance. By providing quality variability on a glyph-by-glyph basis, a relatively simple glyph, such as those used for Latin characters, may be presented using low quality. However, a more complex glyph which may require a clear presentation of its more intricate detail for a proper comprehension of the glyph, such as various Chinese characters, are presented using high quality. In this manner, computing resources may be preserved or tailored on a glyph-by-glyph basis.
