以下是演示绽放效果的示例。我们将绘制一个文本“Welcome to Tutorialspoint”,并使用阈值 1.0 对其应用泛光效果。
将此代码保存在名称为的文件中 BloomEffectExample.java.
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.effect.Bloom;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;
import javafx.scene.text.Font;
import javafx.scene.text.FontWeight;
import javafx.scene.text.Text;
public class BloomEffectExample extends Application {
@Override
public void start(Stage stage) {
//Creating a Text object
Text text = new Text();
//Setting font to the text
text.setFont(Font.font(null, FontWeight.BOLD, 40));
//setting the position of the text
text.setX(60);
text.setY(150);
//Setting the text to be embedded.
text.setText("Welcome to Tutorialspoint");
//Setting the color of the text
text.setFill(Color.DARKSEAGREEN);
//Instantiating the Rectangle class
Rectangle rectangle = new Rectangle();
//Setting the position of the rectangle
rectangle.setX(50.0f);
rectangle.setY(80.0f);
//Setting the width of the rectangle
rectangle.setWidth(500.0f);
//Setting the height of the rectangle
rectangle.setHeight(120.0f);
//Setting the color of the rectangle
rectangle.setFill(Color.TEAL);
//Instantiating the Bloom class
Bloom bloom = new Bloom();
//setting threshold for bloom
bloom.setThreshold(0.1);
//Applying bloom effect to text
text.setEffect(bloom);
//Creating a Group object
Group root = new Group(rectangle, text);
//Creating a scene object
Scene scene = new Scene(root, 600, 300);
//Setting title to the Stage
stage.setTitle("Sample Application");
//Adding scene to the stage
stage.setScene(scene);
//Displaying the contents of the stage
stage.show();
}
public static void main(String args[]){
launch(args);
}
}
