JavaFX Multiple Transformations

Multiple Transformation

We can make use of the combined effect of all the transformations on a node. For this purpose, JavaFX provides the method addAll(Transform obj1, Transform obj2….) which can be called anonymously on the reference returned by <node-obj>.getTransforms() method.

The following example implements all transformations on a rectangle.

Example:

The following example illustrates implementation of all the transformation on an object. Here, we have created a rectangle and applied the transformations i.e. translation, rotation, scaling and shearing on it.

  package application;    import javafx.application.Application;  import javafx.scene.Group;  import javafx.scene.Scene;  import javafx.scene.paint.Color;  import javafx.scene.shape.Circle;  import javafx.scene.shape.Rectangle;  import javafx.scene.transform.Rotate;  import javafx.scene.transform.Scale;  import javafx.scene.transform.Shear;  import javafx.scene.transform.Translate;  import javafx.stage.Stage;  public class MultipleTransformations extends Application{  @Override  public void start(Stage primaryStage) throws Exception {  // TODO Auto-generated method stub  //creating Rectangle and circle   Rectangle rect = new Rectangle(50,10,200,250);  Circle c = new Circle(300,260,100);    //setting properties for the rectangle and circle   c.setFill(Color.LIGHTBLUE);  c.setStroke(Color.BLACK);  rect.setStroke(Color.BLACK);  rect.setFill(Color.LIMEGREEN);  rect.setStrokeWidth(2);    //creating the translate transform   Translate trans=new Translate();  trans.setX(100);  trans.setY(10);    //creating Rotate transform   Rotate rotate = new Rotate();  rotate.setAngle(30);  rotate.setPivotX(50);  rotate.setPivotY(100);    //Creating Scale Transform   Scale scale = new Scale();  scale.setX(1.5);  scale.setY(1.2);  scale.setPivotX(50);  scale.setPivotY(50);    //creating Shear Transform   Shear shear = new Shear();  shear.setX(0.3);    //applying all the transforms to the rectangle   rect.getTransforms().addAll(trans,rotate,scale,shear);    Group root = new Group();  root.getChildren().addAll(rect,c);  Scene scene = new Scene(root,550,500);  primaryStage.setScene(scene);  primaryStage.setTitle(“Multiple Transformation Example”);  primaryStage.show();    }  publicstaticvoid main(String[] args) {  launch(args);  }  }
