Semi transparent polygon


I have an image in my mobile screen. I would like to paint over at a certain area with a
semi transparent polygon. How can I do that?


Hey @bhegedus,

You could try using a shape control, and changing the opacity. Or you could use a rectangle control if you wanted to eliminate the border as well.

Let me know if that helps!


Depending on the shape of the polygon, you may need to create it in a vector paint app, give it a semi-transparent fill, and then export as PNG. Then you can place it as an image in Balsamiq.
