Protected Member Functions inherited from ImageManipulation.Quantizer
	Quantizer (bool singlePass)
	Construct the quantizer.

void	FirstPass (BitmapData sourceData, int width, int height)

Constructor & Destructor Documentation

ImageManipulation.OctreeQuantizer.OctreeQuantizer	(	int	maxColors,
		int	maxColorBits
	)

Construct the octree quantizer.

The Octree quantizer is a two pass algorithm. The initial pass sets up the octree, the second pass quantizes a color based on the nodes in the tree.

Parameters

maxColors	The maximum number of colors to return.
maxColorBits	The number of significant bits.

Member Function Documentation

override ColorPalette ImageManipulation.OctreeQuantizer.GetPalette ( ColorPalette original )

protectedvirtual

Retrieve the palette for the quantized image.

Parameters

original Any old palette, this is overrwritten.

override void ImageManipulation.OctreeQuantizer.InitialQuantizePixel ( Color32 * pixel )

protectedvirtual

Process the pixel in the first pass of the algorithm.

Parameters

pixel The pixel to quantize.

This function need only be overridden if your quantize algorithm needs two passes, such as an Octree quantizer.

override byte ImageManipulation.OctreeQuantizer.QuantizePixel ( Color32 * pixel )

protectedvirtual

Override this to process the pixel in the second pass of the algorithm.

Parameters

pixel The pixel to quantize.
