```
public class GreyscaleFilter
extends AbstractPixelwiseFilter
```
A filter that converts images to greyscale, completely desaturating the colours.
In-place filtering: This class supports in-place filtering (the source and destination image may be the same).

    Description copied from class: AbstractPixelwiseFilter
    
    This method is called with a block of ARGB values to be filtered. Subclasses must override this method to implement the actual filtering algorithm by replacing each pixel value in the range argb[start] ... argb[end-1] with the filtered value.
    
    Specified by:
    
    filterPixels in class AbstractPixelwiseFilter
    
    Parameters:
    
    argb - an array of pixel data to filter
    
    start - the index of the first pixel to filter
    
    end - the index of the last pixel to filter, plus one
