Méthodes publiques

Méthode Description
OctreeQuantizer ( ) : System

Initializes a new instance of the OctreeQuantizer class.

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.

Defaults to return a maximum of 255 colors plus transparency with 8 significant bits.

OctreeQuantizer ( int maxColors, int maxColorBits ) : System

Initializes a new instance of the OctreeQuantizer class.

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

Méthodes protégées

Méthode Description
GetPalette ( System.Drawing.Imaging.ColorPalette original ) : System.Drawing.Imaging.ColorPalette

Retrieve the palette for the quantized image
InitialQuantizePixel ( ImageProcessor.Imaging.Colors.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 ( ImageProcessor.Imaging.Colors.Color32 pixel ) : byte

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