3color combines three FITS images of equal size to a single 24 bit
image in PPM format. All input files are first scaled to 256 gray lev-
els before conversion to a single 24 bit image file.

Files
Input files shall all comply with FITS format. The output file is in
PPM (Portable PixMap) format, which should be fairly easy to convert to
any kind of more convenient image format for export. As PPM images are
portable, they are bulky and usually not suitable for export.
