I thought the same thing (also gimp and zgv), but I noticed the subject read,
"CLI app", i.e. command-line interface app.  I don't know of any off the top
of my head.  Maybe 'man -k pnm' will turn up something useful?

The GIMP has a batch mode for running off the command line.

ImageMagick (http://www.wizards.dupont.com/cristy/ImageMagick.html)
