Abstract: A method, computer graphical user interface tool, and computer-readable medium for generating a set of characters for display in gray scale are provided, wherein each character comprises one or more strokes/glyphs, and each stroke/glyph is defined in silhouette-oriented representation. The method includes generally six steps. First, a set of characters is displayed, wherein each character comprises one or more strokes/glyphs, and all of the strokes/glyphs are represented by a set of basic strokes/glyphs, each basic stroke/glyph topographically representing a set of similarly-shaped strokes/glyphs. Second, each basic stroke/glyph is defined in silhouette-oriented representation. Third, each stroke/glyph forming each character is defined in silhouette-oriented representation. Fourth, the set of characters is rendered in gray scale. Fifth, the proper appearance of the characters is verified.
