Quantizer

All Known Implementing Classes:

OctTreeQuantizer
```
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

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`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
    
    count - the count of pixels
  - buildColorTable
```
int[] buildColorTable()
```
  - getIndexForColor
```
int getIndexForColor(int rgb)
```
