System and method for improving an appearance of a raster image comprising glyph shapes |
摘要 |
A system and method for improving the appearance of a raster image that includes glyph shapes is provided. A pair of glyph shapes is defined. Each glyph shape is differentiated two-dimensional machine readable data of relatively uniform appearance. Each of the glyph shapes is assigned to a different bit value. Digital data from an input source is encoded into a bitmap image space by representing a bit value for each item of the digital data as the glyph shape corresponding to that bit value. A raster image of the encoded glyph shapes is generated from the bitmap image space.
