RandomNoiseDitherer Class

public sealed class RandomNoiseDitherer : IDitherer

Public NotInheritable Class RandomNoiseDitherer
	Implements IDitherer

public ref class RandomNoiseDitherer sealed : IDitherer

[<SealedAttribute>]
type RandomNoiseDitherer =  
    class
        interface IDitherer
    end

The RandomNoiseDitherer type exposes the following members.

	Name	Description
	RandomNoiseDitherer	Initializes a new instance of the RandomNoiseDitherer class. See the Examples section for some examples.

	Name	Description
	InitializeAsync	Gets an IDitheringSession instance potentially asynchronously that can be used to dither the result of the specified IQuantizingSession applied to the specified source. If ditherer is a known ditherer that can be evaluated quickly, then this method might be executed synchronously. This method is available in.NET Framework 4.0 and above. (Defined by DithererExtensions.)

The RandomNoiseDitherer generates some random white noise to the quantized source.

Tip
There are also a couple of ditherers with non-random noise-like patterns in this library. See also the OrderedDitherer.BlueNoise property and the InterleavedGradientNoiseDitherer class.

To get always the same result for the same source image and quantizer you can specify a seed when initializing a RandomNoiseDitherer instance. Please note though that specifying a seed prevents parallel processing, which makes performance worse on multi-core systems.

The following table demonstrates the effect of the dithering:
