public class FastBlurFilter extends AbstractFilter
A fast blur filter can be used to blur pictures quickly. This filter is an implementation of the box blur algorithm. The blurs generated by this algorithm might show square artifacts, especially on pictures containing straight lines (rectangles, text, etc.) On most pictures though, the result will look very good.
The force of the blur can be controlled with a radius and the default radius is 3. Since the blur clamps values on the edges of the source picture, you might need to provide a picture with empty borders to avoid artifacts at the edges. The performance of this filter are independant from the radius.
