Saving Tkinter images?

[dustin lee]

I'm pretty new to Tkinter programming so bear with me.  I'm interested
if there is some way to save an image (eg. to a jpeg or png) that has
been drawn to a Tkinter canvas.  I'm guessing there isn't but I
thought I'd at least ask.  I know I can do a screen print if a get
desparate but I'd like to be able to create them programatically.  I
also know about (but haven't used) PIL and gdmodule, I just thought it
would be cool to go directly to an image from Tkinter.

thanks
