foo2oak.c

Linux下的无线网卡通用驱动程序

/*

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

BUGS AND DEFICIENCIES
    - Needs to do color correction
    - Needs to support a better input color file format which includes
      explicit page boundary indications.
