DESCRIPTION
pamflip is mostly backward compatible with pnmflip, but works on PAM
images too.
One way pamflip is not backward compatible with pnmflip is that pnmflip
lets you specify any number of basic flip options, whereas pamflip
requires exactly one. (pamflip provides the -xform option for request‐
ing multiple transformations, though). Because of this incompatibil‐
ity, pnmflip still exists as a separate program, and all it does is
translate its options to pamflip style and run pamflip.
You should not make any new use of pnmflip and if you modify an exist‐
ing use, you should upgrade to pamflip.
