OK, this works.
But might it be a possible goal for Matplotlib to be able
to assemble these PNGs into an APNG?

Until then, this can be done with a FireFox 3 extension:

I don't think it makes sense for mpl to do this; it seems to me to be inherently a different sort of operation from plotting, and one that would be done best by something like gifsicle in a post-processing mode.

I agree with Eric, that it would be probably overextending matplotlib too much to support this natively.

However, it might be nice to have a self-contained function that would call out to mencoder or ImageMagick to create an animation from a list of PNGs. That would make it easier to automate the creation of animations directly from matplotlib scripts. Of course, there's nothing stopping anyone from doing that in their own scripts now -- it just might be more convenient and obvious to have it "built in" to matplotlib. I think it's fair to say though that this function should not add any build dependencies, and have only optional runtime dependencies (meaning only if you want to save animations).

But it needs someone to take it on, and most importantly be willing to support the numerous platform and installation issues that are likely to arise. Any takers?
