C# Class Accord.Imaging.ColorReduction.SierraColorDithering

Color dithering using Sierra error diffusion.

The image processing routine represents color dithering algorithm, which is based on error diffusion dithering with Sierra coefficients. Error is diffused on 10 neighbor pixels with next coefficients:

| * | 5 | 3 | | 2 | 4 | 5 | 4 | 2 | | 2 | 3 | 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 dithering routine (use default color table) SierraColorDithering dithering = new SierraColorDithering( ); // apply the dithering routine Bitmap newImage = dithering.Apply( image );
