ABSTRACT:
A method for reducing the obtrusiveness of artifacts appearing in a glyph shape code image space includes encoding digital data values as a glyph shape code, such that the shape code is composed of glyphs having shapes that encode digital data values. Each distinct data value that is encoded is represented by the shape of a glyph, and these glyphs are spatially distributed in a bitmap image space. The bitmap image space is analyzed to determine the presence of artifacts within the bitmap image space, and a raster image is generated in which at least a single dot is placed within at least one of the artifacts in the image space.
