ErrorDiffusionDithererSierraLite Property

Gets an ErrorDiffusionDitherer instance using a small two-line filter proposed by Frankie Sierra. Uses a 3x2 matrix so it has the same performance as the Floyd-Steinberg algorithm and also produces a quite similar result.

C#

public static ErrorDiffusionDitherer SierraLite { get; }

VB

Public Shared ReadOnly Property SierraLite As ErrorDiffusionDitherer
	Get

C++

public:
static property ErrorDiffusionDitherer^ SierraLite {
	ErrorDiffusionDitherer^ get ();
}

F#

static member SierraLite : ErrorDiffusionDitherer with get

Property Value

ErrorDiffusionDitherer

Examples

The following example demonstrates how to use the ditherer returned by this property:

C#

public static IReadWriteBitmapData ToDitheredSierraLite(IReadWriteBitmapData source, IQuantizer quantizer)
{
    IDitherer ditherer = ErrorDiffusionDitherer.SierraLite;

    // a.) this solution returns a new bitmap data and does not change the original one:
    return source.Clone(quantizer.PixelFormatHint, quantizer, ditherer);

    // b.) alternatively, you can perform the dithering directly on the source bitmap data:
    source.Dither(quantizer, ditherer);
    return source;
}

The example above may produce the following results:

Original image	Quantized and dithered image
Color hues with alpha gradient	Quantizing with system default 8 BPP palette
Grayscale color shades	Quantizing with black and white palette

Tip
