BoxBlur class is used to create box blur effect using a simple box filter kernel, with separately configurable sizes in both dimensions, and an iteration parameter that controls the quality of the resulting blur.

 

BoxBlur class provides following constructors to define BoxBlur instance.

 

public BoxBlur()

public BoxBlur(double width, double height, int iterations)

width: the horizontal dimension of the blur effect. Width specifies horizontal blurness.

height: the vertical dimension of the blur effect. ‘height’ specifies vertical blurness.

iterations: the number of times to iterate the blur effect to improve its "quality" or "smoothness"
