Chapter 13, Problem 11SA

Program Plan Intro

BoxBlur class:

• The class “BoxBlur” blurs pixels of an image.
• The smoothness of “BoxBlur” effect could be increased by increasing iterations count.
• The “setIterations” method could be used to set iteration count.

Example:

The example for “BoxBlur” class is given below:

BoxBlur bx = new BoxBlur();

Bx.setIterations(3);

Here, “bx” denotes objects of “BoxBlur” class. The given code defines a constructor and sets count of iterations.

GaussianBlur class:

• The class “GaussianBlur” blurs pixels in an image.
• The blurriness of “GaussianBlur” could be increased or reduced by changing blur radius.
• The blurring effect would increase with radius.

Example:

The example for “GaussianBlur” class is given below:

BoxBlur bx = new GaussianBlur();

Bx.setRadius(10.0);

Here, “bx” denotes object of “GaussianBlur” class. The given code defines a constructor and sets blur radius.

MotionBlur class:

• The class “MotionBlur” blurs pixels in an image.
• It blurs pixels in a certain direction.
• The “setAngle” method can change direction.
• The blurriness of “MotionBlur” could be increased or decreased by changing blur radius.
• The blurring effect would increase with radius.

Example:

The example for “MotionBlur” class is given below:

MotionBlur bx = new MotionBlur();

bx.setRadius(10.0);

bx.setAngle(45.0);

Here, “bx” denotes object of “MotionBlur” class. The given code defines a constructor and sets blur radius and angle.
