Remarks

The filter represents binarization filter, which is based on error diffusion dithering with Floyd-Steinberg coefficients. Error is diffused on 4 neighbor pixels with next coefficients:

    | * | 7 |
| 3 | 5 | 1 |

/ 16

The filter accepts 8 bpp grayscale images for processing.

Sample usage:

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

Initial image:
