- Reads two portable anymaps as input. Performs the specified
- arithmetic operation, and produces a portable anymap as
- output. The two input anymaps must be the same width and
- height.
-
- The arithmetic is performed between corresponding pixels in
- the two anymaps, as if maxval was 1.0, black was 0.0, and a
- linear scale in between. Results that fall outside of
- [0..1) are truncated.
-
- All flags can be abbreviated to their shortest unique
- prefix.
