Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`float`	`get(float x, float y)`	Get value of the filter at offset (x, y).
`float`	`getSize()`	Width in pixels of the filter extents.

- Method Detail
  - getSize
```
float getSize()
```
    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.
    
    Returns:
    
    width in pixels
  - get
```
float get(float x,
          float y)
```
    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.
    
    Parameters:
    
    x - x offset in pixels
    
    y - y offset in pixels
    
    Returns:
    
    value of the filter at the specified location
