Error
Gets an ErrorDiffusionDitherer instance using the filter proposed by Jarvis, Judice and Ninke in 1976.
Uses a 5x3 matrix so the processing is slower than by the original Floyd-Steinberg filter but distributes errors in a wider range.

ErrorDiffusionDithererExamples
The following example demonstrates how to use the ditherer returned by this property:
C#
public static IReadWriteBitmapData ToDitheredJarvisJudiceNinke(IReadWriteBitmapData source, IQuantizer quantizer)
{
IDitherer ditherer = ErrorDiffusionDitherer.JarvisJudiceNinke;
// a.) this solution returns a new bitmap data and does not change the original one:
return source.Clone(quantizer.PixelFormatHint, quantizer, ditherer);
// b.) alternatively, you can perform the dithering directly on the source bitmap data:
source.Dither(quantizer, ditherer);
return source;
}The example above may produce the following results:
Original image | Quantized and dithered image |
