All Implemented Interfaces:

java.awt.image.BufferedImageOp
```
public class GaussianBlurFilter
extends AbstractConvolver
```
A filter that applies a Gaussian blur to the source image.
In-place filtering: Unless otherwise noted, filters based on this class support in-place filtering (the source and destination images can be the same).

    Description copied from class: AbstractConvolver
    
    Returns the convolution kernel(s) that should be applied to execute this filter. Typically, array is either length one (non-separable) or length two (separable).
    
    Specified by:
    
    getKernels in class AbstractConvolver
    
    Returns:
    
    an array of non-null convolution kernels
