C# Класс ImageManipulation.Quantizer

Summary description for Class1.

Открытые методы

Метод	Описание
Quantize ( Image source ) : Bitmap	Quantize an image and return the resulting output bitmap.

Защищенные методы

Метод	Описание
FirstPass ( BitmapData sourceData, int width, int height ) : void	Execute the first pass through the pixels in the image.
GetPalette ( System.Drawing.Imaging.ColorPalette original ) : System.Drawing.Imaging.ColorPalette	Retrieve the palette for the quantized image.
InitialQuantizePixel ( Color32 pixel ) : void	Override this to 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.
Quantizer ( bool singlePass ) : System	Construct the quantizer. If you construct this class with a true value for singlePass, then the code will, when quantizing your image, only call the 'QuantizeImage' function. If two passes are required, the code will call 'InitialQuantizeImage' and then 'QuantizeImage'.
SecondPass ( BitmapData sourceData, Bitmap output, int width, int height, Rectangle bounds ) : void	Execute a second pass through the bitmap.

Описание методов

FirstPass() защищенный Метод

Execute the first pass through the pixels in the image.

protected FirstPass ( BitmapData sourceData, int width, int height ) : void
sourceData	System.Drawing.Imaging.BitmapData	The source data.
width	int	The width in pixels of the image.
height	int	The height in pixels of the image.
Результат	void

GetPalette() защищенный абстрактный Метод

Retrieve the palette for the quantized image.

protected abstract GetPalette ( System.Drawing.Imaging.ColorPalette original ) : System.Drawing.Imaging.ColorPalette
original	System.Drawing.Imaging.ColorPalette	Any old palette, this is overwritten.
Результат	System.Drawing.Imaging.ColorPalette

InitialQuantizePixel() защищенный Метод

Override this to 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

Quantize() публичный Метод

Quantize an image and return the resulting output bitmap.

public Quantize ( Image source ) : Bitmap
source	Image	The image to quantize.
Результат	System.Drawing.Bitmap

QuantizePixel() защищенный абстрактный Метод

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

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

Quantizer() защищенный Метод

Construct the quantizer.

If you construct this class with a true value for singlePass, then the code will, when quantizing your image, only call the 'QuantizeImage' function. If two passes are required, the code will call 'InitialQuantizeImage' and then 'QuantizeImage'.

protected Quantizer ( bool singlePass ) : System
singlePass	bool	If true, the quantization only needs to loop through the source pixels once.
Результат	System

SecondPass() защищенный Метод

Execute a second pass through the bitmap.

protected SecondPass ( BitmapData sourceData, Bitmap output, int width, int height, Rectangle bounds ) : void
sourceData	System.Drawing.Imaging.BitmapData	The source bitmap, locked into memory.
output	System.Drawing.Bitmap	The output bitmap.
width	int	The width in pixels of the image.
height	int	The height in pixels of the image.
bounds	System.Drawing.Rectangle	The bounding rectangle.
Результат	void
