--- Comment #13 from Fabian Maurer dark.shadow4@web.de --- Yeah, it's slower since it renders into an temporary HDC and then blends the result onto the image. Thing is, the function for that uses "GdipBitmapGetPixel" and "GdipBitmapSetPixel" internally, so it's not too performant. But it looks a lot better.
