Are there a implementation (API) of Alpha Compositing for .NET. The Wikipedia means that Windows has a native implementation of it. Of course it can be do with pixel manipulation but this will be a bad performance. If there are a native implementation then we should use it.
If there is no native implementation that can be used from .NET then there is a library that implement it already?
In Java there is a class AlphaComposite and is very simple.
Windows GDI+ does provide some alpha blending. In .NET, it’s exposed by the
Graphicsclass, which is quite well documented. For alpha blending specifically, start with Alpha Blending Lines and Fills.
