public interface Quantizer

The interface for an image quantizer. The addColor method is called (repeatedly if necessary) with all the image pixels. A color table can then be returned by calling the buildColorTable method.

Method Summary

void	addPixels(int[] pixels, int offset, int count) Add pixels to the quantizer.
int[]	buildColorTable()
int	getIndexForColor(int rgb)
void	setup(int numColors) Initialize the quantizer.

Method Detail

setup

void setup(int numColors)

Initialize the quantizer. This should be called before adding any pixels.

Parameters:

numColors - the number of colors we're quantizing to.

addPixels

void addPixels(int[] pixels,
               int offset,
               int count)

Add pixels to the quantizer.

Parameters:

pixels - the array of ARGB pixels

offset - the offset into the array
