OCR program for pnm files
GNU Ocrad is an OCR (Optical Character Recognition) program based on a
feature extraction method. It reads images in pbm (bitmap), pgm
(greyscale) or ppm (color) formats and produces text in byte (8-bit) or
UTF-8 formats.  The pbm, pgm and ppm formats are collectively known as
pnm.
