GaussianBlur is a part of JavaFX. GaussianBlur is an implementation of a blur effect using a Gaussian convolution kernel, with a configurable radius.

Constructors of the class:

1. GaussianBlur(): Creates an new object of GaussianBlur.
2. GaussianBlur(double r): Creates a new Object of GaussianBlur with a specified radius.

Commonly Used Methods:

Below programs illustrate the use of GaussianBlur class:

1. Java program to import an image and add GaussianBlur 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 GaussianBlur effect is created with a specified level passed as parameters and the effect is set to the image view using setEffect() function.
   
   

   
   
   

   // Java program to import an image  // and add Gaussian Blur effect to it import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.*; import javafx.scene.layout.*; import javafx.stage.Stage; import javafx.scene.image.*; import javafx.scene.effect.*; import java.io.*; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.scene.Group;    public class gaussian_blur_1 extends Application {        // launch the application     public void start(Stage stage) throws Exception     {            // set title for the stage         stage.setTitle("GussianBlur Example");            // create a input stream         FileInputStream input = new FileInputStream("D:\\GFG.png");            // create a image         Image image = new Image(input);            // create a image View         ImageView imageview = new ImageView(image);            // create a gaussian blur effect         GaussianBlur gaussian_blur = new GaussianBlur();            // set effect         imageview.setEffect(gaussian_blur);            // create a VBox         VBox vbox = new VBox(imageview);            // create a scene         Scene scene = new Scene(vbox, 200, 200);            // set the scene         stage.setScene(scene);            stage.show();     }        // Main Method     public static void main(String args[])     {            // launch the application         launch(args);     } }

2. Java program to import an image and add GaussianBlur effect to it with a specified radius: 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 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 GaussianBlur effect is created with a specified level passed as parameters and the effect is set to the image view using setEffect() function. The radius of the GaussianBlur is specified using the setRadius() function.
