NAME 3color - 3 color combination SYNOPSIS 3color <red> <green> <blue> <outname> DESCRIPTION 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 levels before conversion to a single 24 bit image file. Example: > 3color h2.fits feII.fits brg.fits orion.ppm OPTIONS 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.
