Abstract
Abstract Aspects for achieving enhanced glyphs of a font are presented. In a method aspect, the method includes determining a glyph layer description for a selected glyph, and accessing at least one contour for the selected glyph. The method further includes accessing at least one layer style for the at least one contour of the selected glyph, and rendering the selected glyph in accordance with the at least one layer style to produced an enhanced glyph. In a system aspect, the system includes a mechanism for providing a hinted path. A glyph layer processor is coupled to the mechanism for providing and receives the hinted path. The glyph layer processor outputs enhanced glyph data. A drawing client for receiving the enhanced glyph data from the glyph layer processor for output from a computer system is further included.
