John, Also, the pbm2ap C converter also has the following (not in MAKEAP.BA):
1. A way of detecting repeated patterns and creating a small (I think up to 8 entry) dictionary of single character replacements on arbitrary length "duplicated strings". 2. Scanning to see if an image is "mostly black" or "mostly white" an changing the encoding accordingly. 3. The ability to adapt to 6,-11 pixel runs where there are 2-4 pixels the same color prior to the encoded 6-pixel pattern (i.e. a normal 6-pixel ASCII byte can represent up to 11 pixels if there are only a "few" pixels that match the first bit represented by the encoded value.
