ABSTRACT:
Methods, apparatus, including computer program products, and systems implement and use techniques for rendering glyphs. A representation of a glyph is generated, the glyph to be rendered at a size on an output device having a device resolution. A bitmap representation of the glyph is generated using a first anti-aliasing process in a first direction and using a different second anti-aliasing process in a second direction.
