Summary:A method of developing a configuration for encoding a data glyph block such that the data capacity of the data glyph block is maximized or made optimal. The method of forming an encoded configuration for a data glyph block containing one or more occlusions includes performing one or more of cut off of one or more occlusions, enlargement of one or more occlusions and merger of two or more occlusions, and encoding the cut off, enlarged or merged occlusions with synchronization lines, and encoding any remaining occlusions by error correction, thereby forming the encoded configuration. A method of embedding a data glyph block containing occlusions into an image by halftone rendering of glyph marks, again preferably with the data glyph block having maximal or optimal data capacity, is also set forth.
