C# Class ImageManipulation.OctreeQuantizer

Quantize using an Octree

Inheritance: Quantizer

Public Methods

Method	Description
OctreeQuantizer ( int maxColors, int maxColorBits ) : System	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.

Method	Description
GetPalette ( System.Drawing.Imaging.ColorPalette original ) : System.Drawing.Imaging.ColorPalette	Retrieve the palette for the quantized image.
InitialQuantizePixel ( Color32 pixel ) : void	Process the pixel in the first pass of the algorithm. This function need only be overridden if your quantize algorithm needs two passes, such as an Octree quantizer.
QuantizePixel ( Color32 pixel ) : byte	Override this to process the pixel in the second pass of the algorithm.

Retrieve the palette for the quantized image.

protected GetPalette ( System.Drawing.Imaging.ColorPalette original ) : System.Drawing.Imaging.ColorPalette
original	System.Drawing.Imaging.ColorPalette	Any old palette, this is overrwritten.
return	System.Drawing.Imaging.ColorPalette

Process the pixel in the first pass of the algorithm.

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

protected InitialQuantizePixel ( Color32 pixel ) : void
pixel	Color32	The pixel to quantize.
return	void

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.

public OctreeQuantizer ( int maxColors, int maxColorBits ) : System
maxColors	int	The maximum number of colors to return.
maxColorBits	int	The number of significant bits.
return	System

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

protected QuantizePixel ( Color32 pixel ) : byte
pixel	Color32	The pixel to quantize.
return	byte
