- DMD bitmap to PostScript translator. Much of the code came from abm,
- which was written by Guy Riddle.
- By default 6 byte patterns are used to encode the output bitmap. Use
- the -b option to change the pattern size. Bitmaps are unpacked one
- scanline at a time and re-encoded in a format that looks like,
- bytes patterns count
- where bytes and count are decimal integers and patterns is a series
- of hex digits. Bytes is the number of bytes represented by the hex
- pattern, and count is the number of additional times the pattern
- should be repeated. For example,
- 2 FFFF 4
- 5 FFFFFFFFFF 1
- 10 FFFFFFFFFFFFFFFFFFFF 0
- all represent 10 consecutive bytes of ones. Scanlines are terminated
- by a 0 on a line by itself.
