原文:https://www.geeksforgeeks.org/javafx-motionblur-class/

MotionBlur 是 JavaFX 的一部分。运动模糊类使用高斯卷积核实现运动模糊效果，具有可配置的半径和角度。运动模糊类继承效果类。

类的构造函数:

运动模糊():创建一个运动模糊的新对象。
运动模糊(双 a，双 r) :用指定的角度和半径创建一个新的运动模糊对象。

常用方法:

方法	说明
getAngle()	返回运动模糊对象的角度
跟踪半径()	返回运动模糊对象的半径
getInput()	返回运动模糊对象的输入
设置角度(双 v)	设置运动模糊对象的角度
轨迹半径(双 v)	设置运动模糊对象的半径
设置输入(效果五)	设置运动模糊对象的输入

下面的程序说明了运动模糊类的使用:

Java program to import an image and add Motion Blur 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 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 MotionBlur effect is created with a specified level passed as parameters and the effect is set to the image view using setEffect() function.

```java // Java program to import an image and // add Motion Blur 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 motion_blur_1 extends Application {

// launch the application     public void start(Stage stage) throws Exception     {

// set title for the stage         stage.setTitle("MotionBlur 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 Motion blur effect         MotionBlur motion_blur = new MotionBlur();

// set effect         imageview.setEffect(motion_blur);

// 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);     } } ```

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 MotionBlur effect is created with a specified level passed as parameters and the effect is set to the image view using setEffect() function. The radius and the angle for the motion blur is specified using the setRadius() and setAngle() function.
