How can I let the user paint an area and test if it is done?

Hi John!

I just posted an example that might be roughly (maybe too roughly ) what You are looking for - or at least in the ballpark - but there is no check to see if any painting is done. You could add that "feature" by having the desired clicked element(s) register the click and check to see if the element(s) qualified as having finished painting the area. This scenario would of course take JavaScript to implement.

@Luciano Here is a thread on the Forum that appears to be similar to what You are asking. In particular look at the very last Hype project on the page by @strmiska. This example uses SVGs but You may see a way to shift it to “.pngs” - or decide that SVGs are the better route.
