MotionBlur is a part of JavaFX. MotionBlur class implements motion blur effect using a Gaussian convolution kernel, with a configurable radius and angle. MotionBlur class inherits Effect class.
Constructors of the class:
- MotionBlur(): Creates a new object of MotionBlur.
- MotionBlur(double a, double r): Creates a new object of MotionBlur with specified angle and radius.
Commonly Used Methods:
Method | Explanation |
---|---|
getAngle() | Return the angle of the MotionBlur object |
getRadius() | Return the radius of the MotionBlur object |
getInput() | Return the input of the MotionBlur object |
setAngle(double v) | Sets the angle of the MotionBlur object |
getRadius(double v) | Set the radius of the MotionBlur object |
setInput(Effect v) | Sets the input of the MotionBlur object |
Below programs illustrate the use of MotionBlur class:
- Java program to import an image and add Motion Blur effect to it: In this program a FileInputStream is created and an image is taken as input from a file. Image named image is created using the input from the file input stream. From the image, an image view object is created and it is added to the VBox. The VBox is then added to the scene and the scene is added to the stage. A MotionBlur effect is created with a specified level passed as parameters and the effect is set to the image view using setEffect() function.
