-> PredefinedColorsQuantizer Parameters
- pixelFormat PixelFormat
- The PixelFormat to get a quantizer for.
- backColor Color (Optional)
- Colors with alpha (transparency), which are considered opaque will be blended with this color before quantization.
The Color.A property of the background color is ignored. This parameter is optional.
Default value: The bitwise zero instance of Color, which has the same RGB values as Black. - alphaThreshold Byte (Optional)
- Specifies a threshold value for the Color.A property,
under which a quantized color is considered completely transparent. This parameter is optional.
Default value: 128.
Return Value
PredefinedColorsQuantizerA PredefinedColorsQuantizer instance that is compatible with the specified pixelFormat.
