InversionFilter (Strange Eons API)

  - - ca.cgjennings.graphics.filters.InversionFilter

All Implemented Interfaces:

java.awt.image.BufferedImageOp
```
public class InversionFilter
extends AbstractPixelwiseFilter
```
An image filter that inverts the pixel values of the source image, producing a negative image. The alpha channel is unaffected. For more fine-grained control over which channels are affected, use a ChannelSwapFilter instead. Or, to invert just the alpha channel, use an AlphaInversionFilter.
In-place filtering: This class supports in-place filtering (the source and destination images 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
