I've used paint.net in the past to do very simple image manipulation (resize, crop, etc). Now I want to do something advanced (for me anyway): I'd like to overlay semi-transparent pie slices on top of an overhead property pic to show sprinkler head locations (apex of pie shape) and the water throw (radius of slice) of each head. I've been unable to find a way in paint.net to draw pie slices or an option for opaqueness(?). Can someone point me to some relevant how-tos or give me some ideas on how I might accomplish this?
Thanks.
