/*
GENERAL
This program converts pbm (B/W) images, 2-bit pgm (grayscale), and
1-bit- or 2-bit-per-pixel cmyk images (all produced by ghostscript)
to Oak Technolgies JBIG format.
With this utility, you can print to some HP printers, such as these:
- HP LaserJet 1500
- Kyocera Mita KM-1635: -z1 (rotate 90)
- Kyocera Mita KM-2035: -z1 (rotate 90)
BUGS AND DEFICIENCIES
- Needs to do color correction
- Needs to support a better input color file format which includes
explicit page boundary indications.
