Quantize using an Octree

Наследование: Quantizer

Открытые методы

Метод	Описание
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

Метод	Описание
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
Результат	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
Результат	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
Результат	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
Результат	byte
