bmptopnm - convert a BMP file into a portable anymap
Reads a Microsoft Windows or OS/2 BMP file as input. Produces a PBM, PGM, or PNM
image as output. If the input is colormapped and contains only black and
white, the output is PBM. If the input is colormapped and contains only black
white and gray, the output is PGM. Otherwise, the output is PPM.
This program cannot convert BMP files with compressed (run length encoded) image
data. It recognizes the compression and issues an error message.
This program cannot convert BMP files with 16 bits per pixel (only because the
author did not have a complete specification for them). It recognizes the
format and issues an error message.
