JavaFX | SepiaTone Class

SepiaTone class is a part of JavaFX. SepiaTone class is used to add a sepia tone effect to the image which is similar to the antique photographs. On applying SepiaTone effect a reddish brown tone appears on the image.

Constructors of the class:

1. SepiaTone(): Creates a new object of SepiaTone class.
2. SepiaTone(double l): Creates a new SepiaTone object with specified level.

Commonly Used Methods:

Method	Explanation
getInput()	Returns the value of property input.
setInput(Effect v)	Sets the value of property input.
setLevel(double v)	Sets the value of level of Sepia Tone object.
getLevel()	Returns the value of level of Sepia Tone object.

Below programs illustrate the use of SepiaTone class:

1. Java program to import an image and add SepiaTone 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 file input stream. From the image a 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 SepiaTone 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 SepiaTone 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 sepia_tone_1 extends Application {
   
       // launch the application
       public void start(Stage stage) throws Exception
       {
   
           // set title for the stage
           stage.setTitle("SepiaTone 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 sepia_tone effect
           SepiaTone sepia_tone = new SepiaTone(0.5);
   
           // set effect
           imageview.setEffect(sepia_tone);
   
           // 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 set SepiaTone effect to it. The Level of the SepiaTone effect can be controlled using the button: 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 SepiaTone effect is created with a specified level passed as parameters and the effect is set to the image view using setEffect() function. A Button named button is created which is used to increase the SepiaTone of the image. The button is also added to the VBox. The SepiaTone of the image is increased using the setLevel() function.The events related to button is handled using EventHandler.

   // SepiaTone effect to it. The Level of the
   // SepiaTone effect can be controlled
   // using the button

       public void start(Stage stage) throws Exception
       {
   
           // set title for the stage
           stage.setTitle("SepiaTone Example");
   
           // create a input stream
           FileInputStream input = new FileInputStream("D:\\GFG.png");

           Image image = new Image(input);

           // create a sepia_tone effect
           SepiaTone sepia_tone = new SepiaTone(level);
   
           // create a button
           Button button = new Button("increase");
   
           // action event
           EventHandler<ActionEvent> event = new EventHandler<ActionEvent>() {
               public void handle(ActionEvent e)
               {
   
                   // increase the level
                   level += 0.1;
                   if (level > 1)
                       level = 0.0;
   
                   // set Level for sepia_tone
                   sepia_tone.setLevel(level);
               }
           };
   
           // set on action of button
           button.setOnAction(event);
   
           // set effect
           imageview.setEffect(sepia_tone);
   
           // create a VBox
           VBox vbox = new VBox(imageview, button);
   
           // create a scene
           Scene scene = new Scene(vbox, 300, 300);
   
           // set the scene
           stage.setScene(scene);
   
           stage.show();
       }
   
       // Main Method
       public static void main(String args[])
       {
   
           // launch the application
