Chapter 13.3, Problem 13.22CP

Explanation of Solution

effect class:

• The class “effect” is used to apply special effects for nodes in scene graph.
• The images are filtered by adding effects such as blurs as well as color adjustments.
• The “effect” classes includes:
  • DropShadow:
    • It creates a shadow appearing behind a node.
    • The attributes like radius, color as well as offset of shadow could be defined.
  • InnerShadow:
    • It creates a shadow appearing inside node edges.
    • The attributes like radius, color as well as offset of shadow could be defined.
  • ColorAdjust:
    • The hue, brightness, saturation as well as contrast of images could be adjusted.
  • BoxBlur:
    • It creates a blurring effect using box blur algorithm.
  • GaussianBlur:
    • It creates a blurring effect using Gaussian algorithm.
  • MotionBlur:
    • It blurs image pixels in a particular direction...
