C# Class Accord.Imaging.ColorReduction.BurkesColorDithering

Color dithering using Burkes error diffusion.

The image processing routine represents color dithering algorithm, which is based on error diffusion dithering with Burkes coefficients. Error is diffused on 7 neighbor pixels with next coefficients:

| * | 8 | 4 | | 2 | 4 | 8 | 4 | 2 | / 32

The image processing routine accepts 24/32 bpp color images for processing. As a result this routine produces 4 bpp or 8 bpp indexed image, which depends on size of the specified color table - 4 bpp result for color tables with 16 colors or less; 8 bpp result for larger color tables.

Sample usage:

// create color image quantization routine ColorImageQuantizer ciq = new ColorImageQuantizer( new MedianCutQuantizer( ) ); // create 8 colors table Color[] colorTable = ciq.CalculatePalette( image, 8 ); // create dithering routine BurkesColorDithering dithering = new BurkesColorDithering( ); dithering.ColorTable = colorTable; // apply the dithering routine Bitmap newImage = dithering.Apply( image );
