以下程序是演示高斯模糊效果的示例。在此,我们绘制了一个填充了 DARKSEAGREEN 颜色的文本“Welcome to Tutorialspoint”,并对其应用了高斯模糊效果。
将此代码保存在名称为的文件中 GaussianBlurEffectExample.java.
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
import javafx.scene.text.Font;
import javafx.scene.text.FontWeight;
import javafx.scene.text.Text;
import javafx.scene.effect.GaussianBlur;
public class GaussianBlurEffectExample 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 added.
text.setText("Welcome to Tutorialspoint");
//Setting the color of the text
text.setFill(Color.DARKSEAGREEN);
//Instantiating the GaussianBlur class
GaussianBlur gaussianBlur = new GaussianBlur();
//Setting the radius to apply the Gaussian Blur effect
gaussianBlur.setRadius(10.5);
//Applying Gaussian Blur effect to the text
text.setEffect(gaussianBlur);
//Creating a Group object
Group root = new Group(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);
}
}
