public class Dither
extends java.lang.Object
```
The Dither provides the dithering capability for reducing colors of an image to 2, 4, 8, 16, 32, 64, 128 or 256 colors. The real number of colors at the end of color reduction depends on the color profile of the image under reduction.
Currently the following two dithering algorithm's are supported :

    Analize and reduce the number of colors of the given image. Depending on the image and the algorithm, the result may be a new BufferedImage or the same simply returned. If the number of colors in the image is less than required number, no image manipulation is done and the same image is returned.
    
    Parameters:
    
    image - The BufferedImage to analize for color reduction
    
    nCol - The maximum number of colors allowed in the result
    
    transparency - The transparency color of the image or -1 if there is no specific transparency color.
    
    bgcolor - The background color. This - if not -1 - is mixed into the image before reducing colors.
    
    algorithm - Indicate the dithering algorithm to use. Take one of the above constants
    
    Returns:
    
    The same image if no color reduction is needed or a new one if color reduction was needed.
