Img Software Set

Img Software Set is an image processing toolkit developed by Paul Raveling. It has a native image format, which often uses multiple files per image.


 * .p: Colormapped image
 * .a: Image attributes
 * .r, .g, .b: Red, green, blue components

Image files may be compressed, and have an extra .Z extension.

It seems that this software, or an earlier manifestation of it, was also called the Img-whatnot toolkit. We have not been able to confirm or explain this name.

Identification
At least some files begin with ASCII "".

Files contain segments tagged with " ", " ", and " ".
