Specifies how images are dithered with a reduced color palette.
public enum class DitherTypepublic enum DitherTypetype DitherType = Public Enum DitherType- Inheritance
Fields
| Name | Value | Description |
|---|---|---|
| None | 0 | No dithering is performed. Pixels in the source bitmap are mapped to the nearest color in the palette specified by the palette parameter of the ConvertFormat(PixelFormat, DitherType, PaletteType, ColorPalette, Single) method. This algorithm can be used with any palette other than Custom. |
| Solid | 1 | No dithering is performed. Pixels in the source bitmap are mapped to the nearest color in the palette specified by the palette parameter of the ConvertFormat(PixelFormat, DitherType, PaletteType, ColorPalette, Single) method. This algorithm can be used with any palette. |
| Ordered4x4 | 2 | Algorithm to perform dithering based on the colors in one of the standard fixed palettes. This algorithm can also be used to convert a bitmap to a 16-bits-per-pixel format that has no palette. |
| Ordered8x8 | 3 | Dithering is performed using the colors in one of the standard fixed palettes. |
| Ordered16x16 | 4 | Dithering is performed using the colors in one of the standard fixed palettes. |
| Spiral4x4 | 5 | Dithering is performed using the colors in one of the standard fixed palettes. |
| Spiral8x8 | 6 | Dithering is performed using the colors in one of the standard fixed palettes. |
| DualSpiral4x4 | 7 | Dithering is performed using the colors in one of the standard fixed palettes. |
| DualSpiral8x8 | 8 | Dithering is performed using the colors in one of the standard fixed palettes. |
| ErrorDiffusion | 9 | Dithering is performed based on the palette specified by the palette parameter of the ConvertFormat(PixelFormat, DitherType, PaletteType, ColorPalette, Single) method. This algorithm can be used with any palette. |
Remarks
For information about the ordered and spiral dither types, see the remarks for the Win32 DitherType enumeration. The fixed palette types mentioned there correspond to the PaletteType enumeration.
