JavaFX GaussianBlur

Introduction

The JavaFX GaussianBlur Effect is very similar to the JavaFX BoxBlur Effect. The only difference between the two is that the GaussianBlur effect blurs the nodes using a Gaussian convolution kernel. To implement GaussianBlur on the nodes, JavaFX provides the class javafx.scene.effect.GaussianBlur. This class is instantiated in order to have an effect on the node.

Properties

The following table describes the class's properties as well as the setter methods.

🔥 Property 
    → Description
    → Setter Methods
 

🔥 input

This is an effect property. It represents the effect's input.

setInput(Effect value)

🔥 radius

This property has two types. It represents the blur kernel's radius.

setRadius(Double value)

Constructors

There are two constructors in the class.

🌻 public GaussianBlur() :creates a new instance with the default parameter values.

🌻 public GaussianBlur(double radius): This creates a new instance with the parameters specified.

         message .setUnderline(true);  
         GaussianBlur g = new GaussianBlur();

         Group root = new Group();  
         root.getChildren().add(text);  
         Scene scene = new Scene(root,450,200);  
         primaryStage.setScene(scene);  
         primaryStage.setTitle("GaussianBlur Example");  
         primaryStage.show();  
    }
