I need to create an on-screen shape (circle) that has a fill color, which will blink every X seconds (go from fill color, to white, back to fill color). This is trivial to do...BUT... i want to do it in my own class, so that I can instantiate it numerous times passing it unique coordinates for each instantiation.
How do I do it? Can a class have its own "timer control" in it independent from the form? How would I draw a shape from a class?

This problem is occuring because you are interpolating your image data to a new size, but along the edges there are no pixels to interpolate and .NET uses black pixels for these edges by default. To fix this you need to use an ImageAttributes class in your DrawImage call....
