Also if your image was the exact size as specified in the <Image> tag, then it wouldn't have to scale it and should render it crisply.

I'm not sure this will have the desired effect at a different DPI

Beardo, both the source graphic and the <Image> are both 20 pixels by 20 pixels. As I understand it, the issue comes from WPF. It sort-of wants to disregard the pixel grid of the monitor, so it's logical grid usually won't perfectly line up with the physical grid.

@Zack Width="20" does not mean 20 pixels. It means 20/96 of an inch. If your OS is configured to run at 96 DPI then it is 20 pixels. Now how will your nearest neighbor look on a good monitor, 160 DPI for instance? And how will it look when you print at 300 DPI? You shouldn't optimize for your dev machine.

I also found that for pixel-sized images NearestNeighbor is much better than HighQuality, especially if you combine it with img.Width = imgSource.PixelWidth; img.Height = imgSource.PixelHeight. My client provided some images with different crazy DPI values and I couldn't ask the client to convert them all, so I had to use this hack.
