Abstract
Systems and methods are provided for improved filtering and correcting of glyphs on a GPU. The computational intensity required for filtering and/or rendering can be reduced by pre-calculating some or all of the calculations needed for converting coverage data into corrected pixel values. Additional efficiencies may be realized in some embodiments by transferring data from a CPU to a GPU in an improved format. The improvements can be realized in a variety of graphics formats.
