ABSTRACT:
Method and apparatus, implementing and using techniques for processing a character for display on a raster output device having a resolution defined by a set of output pixel positions. A stem of the character is aligned to a best sub-pixel boundary. The character is rendered at a resolution higher than the resolution of the raster output device. The aligned character is downsampled to the raster output device resolution.
