Creating semi-transparent pie slices on top of pic


Recommended Posts

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.

Hi @Rumpelstiltskin and smileys-smiley-with-sign-580722.gif    

There is a Plugin to make a pie chart, if that helps at all?  And a great tutorial for 'blending' images into each other can be found here.

 

How to install Plugins can be found here.

I think Rumpelstiltskin needs a single pie generator. One that will take into account the various angles at wich a sprinkler sprinks and the distance at which it throws the water. The opacity can be changed in the layers mode. The Cone Shape type proposed by Iron67 has limitations.

@Eli That was only an additional (simplified) suggestion. The pie slice in my first picture is made by the Pie Chart plugin.

This is very easy to do, as the .NET Framework provides an api to create pie slices.

That is what I wanted to say a "pie slice". Thanks toe_head2001 for taking on Rumplestiltskin request. I am sure that there will be other users other than drawing sprinklers. :)
