Color dithering using Sierra error diffusion.

Namespace:  AForge.Imaging.ColorReduction
Assembly:  AForge.Imaging (in AForge.Imaging.dll) Version: 2.2.5.0 (2.2.5.0)

Syntax

C#
public sealed class SierraColorDithering : ColorErrorDiffusionToAdjacentNeighbors

Remarks

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:

Copy 
        | * | 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:

CopyC#
// create dithering routine (use default color table)
SierraColorDithering dithering = new SierraColorDithering( );
// apply the dithering routine
Bitmap newImage = dithering.Apply( image );
