Apparently it might also be possible to do it via AppleScript
(according to http://preserve.mactech.com/articles/mactech/Vol.21/21.03/BasicImageManipulation/index.html)
But both of those seem to focus on image manipulation and completely
skip describing the case of a PDF (or GIF, ...) that contains several
images/pages.
So yes, it might be doable but someone will have to play with
it to see exactly what can be done.
If it can only convert a whole document at a time, I think doc-view
could be adapted to accommodate that requirement.
