ShapedForms
http://www.c-sharpcorner.com/Graphics/Shaped1.jpg
Today Windows always appear with a rectangular shape. What if you could have a window that was shaped like a circle, a square or a triangle or any shape you want.
I discovered tonight you could use regions to in effect clip a window to any shape you want. The effect is almost to look like an active desktop component as you cannot move these shaped windows. Having done this and created some animation on your desktop I wonder if you could load a bitmap as the basis for your windows. Note you lose the titlebars etc but it looks like a useful technique.
Here is the source code. Apologies if its messy but its been a long night searching for how to do this. I have attached the exe as well for Beta 2
Enjoy
