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

None
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.
