```
public float get(float x,
                 float y)
```
    Description copied from interface: Filter
    
    Get value of the filter at offset (x, y). The filter should never be called with values beyond its extents but should return 0 in those cases anyway.
    
    Specified by:
    
    get in interface Filter
    
    Parameters:
    
    x - x offset in pixels
    
    y - y offset in pixels
    
    Returns:
    
    value of the filter at the specified location
  - getSize
```
public float getSize()
```
    Description copied from interface: Filter
    
    Width in pixels of the filter extents. The filter will be applied to the range of pixels within a box of +/- getSize() / 2 around the center of the pixel.
    
    Specified by:
    
    getSize in interface Filter
    
    Returns:
    
    width in pixels
