JavaFX | Reflection Class

Reflection class is a part of JavaFX. The Reflection class is used to add a reflected image below the actual image of the input value. The Reflected image will not respond to mouse events or the containment methods on the input.

Constructors of the class:

1. Reflection(): Creates a new Reflection Object.
2. Reflection(double topOffset, double fraction, double topOpacity, double bottomOpacity): Creates a new Reflection object with the specified topOffset, fraction, topOpacity and bottomOpacity.

Commonly Used Methods:

Below programs illustrate the use of Reflection class:

1. Java program to add a reflection to the image using the reflection class: In this program a FileInputStream is created and an image is taken as input from a file. An 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 Reflection effect is created and the effect is set to the image view using setEffect() function.

   
   

   
   
   

   // Java program to add a reflection to  // the image using the reflection class 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 reflection_1 extends Application {        // launch the application     public void start(Stage stage) throws Exception     {            // set title for the stage         stage.setTitle("reflection 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 reflection effect         Reflection reflection = new Reflection();            // set effect         imageview.setEffect(reflection);            // 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);     } }

   Output:
   

2. Java program to add a reflection to the image using the reflection class and set the top offset, top opacity, bottom opacity and fraction of image which will appear as a reflection: 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 Reflection effect is created and the effect is set to the image view using setEffect() function. The bottom Opacity, top Opacity, top offset, and fraction are set using the setBottomOpacity(), setTopOpacity(), setFraction(), and setTopOffset() function respectively.

   
   

   
   
   

   // Java program to add a reflection to the image // using the reflection class and set the top  // offset, top opacity bottom opacity and fraction // of image which will appear as reflection 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 reflection_2 extends Application {        // launch the application     public void start(Stage stage) throws Exception     {            // set title for the stage         stage.setTitle("reflection 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 reflection effect         Reflection reflection = new Reflection();            // set fraction         reflection.setFraction(0.6);            // set top Opacity         reflection.setTopOpacity(0.3);            // set bottom Opacity         reflection.setBottomOpacity(0.1);            // set top offset         reflection.setTopOffset(0.5);            // set effect         imageview.setEffect(reflection);            // 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);     } }
