There is no build in function for that, only an undo function.
You can make an eraser yourselfe if you provide an erase button that sets the foreground color to the background color :)

That's sufficient if one is drawing on a solid background, however, I'd we great to have a proper eraser functionality, so for instance, it works when one is drawing over an image background. Any plans to implement this?

I've added support for erase mode. Note that it works only on transparent background color.

Simply set PainterController's eraseMode property to true.

Hi,
I already peaked at your code. If you would open a PR, Update the LICENSE file to add your name, and briefly explain in the PR how the erease mode works I would merge it :)

@EPNW
#18
Sorry for not supporting colored background, but I don't have enough time to implement that ATM.

This is finally implemented, seed #18 and 6251475
