Try XINTERANIMATE first. There's an example in the documentation. (At
an IDLDE prompt, type ?xinteranimate and go from there.)

XINTERANIMATE won't do this OOTB. It might not be too hard to hack it
so it will. XINTERANIMATE (which is based on the CW_ANIMATE compound
widget function) keeps its images in a series of off-screen
pixmaps. If you can get a handle to these (not using the term handle
in its technical sense here) you can manipulate them any way you want
via command-line operations. But adding this functionality to the user
interface would not be non-trivial, and not a good thing to do IMHO.

I have an image-loop viewer that could be modified to do what you
want. It's object-based and so relatively easily extensible. If you
want I can dig it up.

There may be other solutions around. Check the usual WWW sites,
starting with David Fanning's:
