Enum DitheringMethod

Namespace: Aspose.Imaging
Assembly: Aspose.Imaging.dll (25.2.0)

Dithering method.

public enum DitheringMethod

Fields

FloydSteinbergDithering = 1

The Floyd-Steinberg dithering. A more complex dithering algorithm, uses nearest neighbors intensity values.

ThresholdDithering = 0

Threshold dithering. Simplest and fastest dithering algorithm.

Examples

The following example loads a raster image and performs threshold and floyd dithering using different palette depth.```csharp [C#]
