update canvas object !

If you just want to use elipses to cut out holes in a canvas I'd strongly recommend you use sprites, because you can made the holes in the scenery look more realistic and stuff.

I put together a nice little example that uses a combination of multiply and erase to create holes that leave a darkish shadow

The effect is more pleasing than an aliased perfect circle in my opinion.

What did you want to use elipses for ?

Another version of the above but adds a light shine to the bottom right of the holes to give depth

You don't need a knife on your hammer to drive nails.

And anyway, you can never find the hammer when you need it.

just add a save/load that supports the canvas and ill be happy.

You can save an image from the canvas by copying it from the canvas to the image manipulator and saving it from there. It even retains alphas for pngs. Or did you mean with the system save function?

Welp, I guess you're right... the Copy From Sprite action works on the Canvas object. I guess I just didn't bother trying before because the Canvas isn't a sprite.
