Dithering using Sierra error diffusion.

The filter represents binarization filter, 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 filter accepts 8 bpp grayscale images for processing.

Sample usage:

// create filter SierraDithering filter = new SierraDithering( ); // apply the filter filter.ApplyInPlace( image );

Initial image:
