How can I serialize the state of the canvas and redraw later on?

[johncrossman]

Hello and thank you in advance.

I will use the "Stick Man" canvas to illustrate what I want to do.

1. Load "Stick Man" canvas in browser
2. Change the position of the arms
3. Save the state of the canvas to database
4. Come back later, load the canvas state from the database
5. The "Stick Man" renders with the modified arm position

Is there a simple way to do this?

Thanks again, John (Software developer at UC Berkeley)
