Dr. Halo was a line of raster image editing software for MS-DOS. It has a well-known device-independent .CUT image format, which uses RLE compression (in a way which is similar to, but not the same as, PackBits). CUT files are sometimes accompanied by .PAL palette files.
There is also a device-dependent .PIC image format. We have not located any details about PIC format.
All CUT images have exactly 8 bits per pixel, but all 8 bits might not be used. It is common for the only color codes used by an image to be 0 and 1.
It is not clear what to do if no palette file is present. Interpreting the image as grayscale, with black=0, seems to be standard practice. But different viewers use different logic for guessing the code that should be interpreted as white.
