[Tutor] >> Best setup for animation? <<
Wed, 28 Feb 2001 16:04:11 -0600
Greetings Chris & All,
I hit this problem just this Sunday. Switching out images is much easier
with Label than Canvas. In fact, it's this easy:
LabelVar['image'] = OtherImage
The rub is you'll have to write all the event handling logic yourself. :-)
So, you can compose two or more images using PIL and switch them out on the
label. As long as they're almost identical, its fairly smooth.
I think Tkinter is fine for doing prototypes of this kind of work. That's
what I'm trying to do.
