A fork of nQuant, specifically Phillipecp's nQuant Leaner And Faster fork. This fork may be used in exactly the same way as the original version, with two additional WuQuantizerBase.QuantizeImage() overloads:

• public Image QuantizeImage(Bitmap image, int alphaThreshold, int alphaFader, int colorCount) - the colorCount parameter indicates the maximum number of colors allowed. Must be between 2 and 256 inclusive.
• public Image QuantizeImage(Bitmap image, int alphaThreshold, int alphaFader, ref int colorCount) - the same, except that when this method returns, colorCount will be changed to the actual computed maximum number of colors in the quantized image.

It also includes a second library, nQuantWpf.Core with a corresponding nQuantWpf command-line program, which performs the same operations using the Windows Presentation Foundation.
