JavaFX Reflection
In the JavaFX application, in order to apply various reflection effect, we use this class. It has the ability to create the reflection of the given object. This effect adds the reflection at the bottom of the node. All methods needed for this purpose are present in the javafx.scene.effect.Reflection class.
Properties and corresponding methods to create Reflection Effect:
1. bottomOpacity
This property is of double type. It is used to represent the bottom opacity of the refelction and the setBottomOpacity( Double value ) method is used to set it.
2. topOffset
This is double type property. It is used to represent the distance between top and bottom side of the reflection and the setTopOffset( Double value ) method is used to set it.
3. input
This is object type property. It is used to represent the input for the effect and the setInput( Effect value ) method is used to set it.
4. fraction
This is double type property. It is used to represent the fraction of input which is to be shown in the reflection and the setFraction( Double value ) method is used to set it.
5. topOpacity
This is double type property. It is used to represent the top opacity of the refelction and the setTopOpacity( Double value ) method is used to set it.
Constructors to create Reflection Effect:
- public Reflection() :
This constructor is used to create the new empty constructor with the default parameters.
- public Reflection(double topOffset, double fraction, double topOpacity, double bottomOpacity) :
This constructor is used to create the new constructor with the specified topOffset, fraction, topOpacity and bottomOpacity parameters.
JavaFX Effect – Image with and without Inner Shadow Effect:
Example:
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.effect.Reflection;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.stage.Stage;
public class EffectUI extends Application {
@Override
public void start(Stage stage) throws Exception
{
Image newimage = new Image("https://icons.iconarchive.com/icons/custom-icon-design/pretty-office-4/256/home-icon.png");
ImageView newimageView = new ImageView(newimage);
Image newimage2 = new Image("https://icons.iconarchive.com/icons/custom-icon-design/pretty-office-4/256/home-icon.png");
ImageView newimageView2 = new ImageView(newimage);
newimageView.setX(140);
newimageView.setY(40);
newimageView2.setX(440);
newimageView2.setY(40);
newimageView.setFitHeight(200);
newimageView.setFitWidth(400);
newimageView2.setFitHeight(200);
newimageView2.setFitWidth(400);
newimageView.setPreserveRatio(true);
newimageView2.setPreserveRatio(true);
Reflection ref = new Reflection();
ref.setBottomOpacity(0.2);
ref.setFraction(12);
ref.setTopOffset(10);
ref.setTopOpacity(0.2);
newimageView2.setEffect(ref);
Group root = new Group(newimageView,newimageView2);
Scene scene = new Scene(root,800,500);
stage.setScene(scene);
stage.setTitle(" JavaFx Reflection Effect example ");
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Output:
In order to create image with and without Reflection in JavaFX, we have to import all the required libraries such as javafx.application.Application, javafx.scene.Group, javafx.scene.Scene, javafx.scene.effect.Reflection, javafx.scene.paint.Color, javafx.scene.effect.BlurType, javafx.scene.image.Image, javafx.scene.image.ImageView, javafx.stage.Stage.
Then we have created one class named EffectUI extending the Application class. Also, we have to override the start method to provide implementation details. This method creates an object of Stage as primaryStage. For the container to hold the image with and without Reflection Effect, a Group object is created which is then passed to the Scene class object.
The image is created using the constructor and various properties are set using setters. The Reflection constructor is created and then using the setEffect, the effect is applied on one image and the other image is kept as it is.
The stage is prepared, the title is set and the show() method is called to display output. In order to run the application, the launch(args) method is called in the main() method. In output Frame like container is displayed with the title, " JavaFX Reflection Effect example”. Also, it displays the image with and without Reflection Effect.
JavaFX Effect – Text with Reflection Effect:
Example:
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.effect.Reflection;
import javafx.scene.paint.Color;
import javafx.scene.text.Font;
import javafx.scene.text.FontPosture;
import javafx.scene.text.FontWeight;
import javafx.scene.text.Text;
import javafx.stage.Stage;
public class EffectUI extends Application {
@Override
public void start(Stage stage) throws Exception
{
Text text = new Text();
text.setText(" Text With Reflection Effect ");
text.setX(100);
text.setY(100);
text.setFont(Font.font("Times New Roman",FontWeight.BLACK,FontPosture.ITALIC,40));
text.setFill(Color.BLACK);
text.setStroke(Color.BROWN);
text.setUnderline(true);
Reflection ref = new Reflection();
ref.setBottomOpacity(0.2);
ref.setFraction(12);
ref.setTopOffset(10);
ref.setTopOpacity(0.2);
text.setEffect(ref);
Group root = new Group(text);
Scene scene = new Scene(root,800,300);
stage.setScene(scene);
stage.setTitle(" JavaFx Reflection Effect example ");
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
