Comment (by nbruin):
OK, I'm afraid the following if a bit of distraction of your core goal.
Without reading any documentation, I would expect G.img() to return an
"image object", rather than the G.save_as_bitmap("filename"). Of course
save_as_bitmap still needs to be told in what format the bitmap should be
saved.
I'm not sure we have an appropriate "image object". We do have PIL in
sage. Try `import Image`. Would it make sense to interface with their
types for an "img" return value?
Obviously, having a "convert to bitmap object" protocol implemented for
all graphics-type objects, together with a save-to-file option on the
bitmap object, would give you the required infrastructure to produce
animations. It may not be the most efficient (or even sufficiently
efficient) way of doing it, though ...
I can understand if you don't want to mess with bitmap objects (whatever
they should be) and just settle for a way to dump a bitmap representation
of objects into a file. However, you might not want to use "img" then,
reserving that word for when someone does want to do that.
