Question

如何将图像设置为第一个场景中的矩形。当我单击“相机”按钮时，第二个场景打开时第一个场景仍处于打开状态。在第二个场景中，当我单击“捕获”按钮时，图像首先从第二个场景开始场景，但没有显示。我检查了图像是否单击，但唯一的问题是它没有以矩形显示。

提供场景控制器代码Java代码

package application;
import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.fxml.Initializable;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.image.Image;
import javafx.scene.layout.AnchorPane;
import javafx.scene.paint.ImagePattern;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;
import javafx.stage.StageStyle;

public class Controller implements Initializable{
@FXML
private Rectangle imageView;
@FXML
private Button button;
@FXML
private AnchorPane rootpane;
@FXML
void click(ActionEvent event) throws IOException {
    Parent root=FXMLLoader.load(getClass().getResource("Selfi.fxml"));
    Scene scene=new Scene(root);
    Stage stage=new Stage();
    stage.initStyle(StageStyle.TRANSPARENT);
    stage.setScene(scene);
    stage.show();


}
public void setImage(Image img)
{
    imageView.setFill(new ImagePattern(img));
}

@Override
public void initialize(URL location, ResourceBundle resources) {
    // TODO Auto-generated method stub 
}}

第一个场景的Fxml代码：-

<?xml version="1.0" encoding="UTF-8"?>

<?import de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.shape.Rectangle?>

<AnchorPane fx:id="rootpane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8.0.171" xmlns:fx="http://javafx.com/fxml/1" fx:controller="application.Controller">
<children>
   <Rectangle fx:id="imageView" arcHeight="5.0" arcWidth="5.0" fill="WHITE" height="200.0" layoutX="177.0" layoutY="14.0" stroke="BLACK" strokeType="INSIDE" width="200.0" />
  <Button fx:id="button" layoutX="246.0" layoutY="227.0" mnemonicParsing="false" onAction="#click">
     <graphic>
        <FontAwesomeIconView glyphName="CAMERA" />
     </graphic>
  </Button>
</children>
</AnchorPane>

第二个场景控制器（用于图像删除）

图片链接：-Image Cliker scene

public class selfiController implements Initializable {

Webcam webcam;
@FXML
private Rectangle videofeddback;
double x,y;

@Override
public void initialize(URL location, ResourceBundle resources) {
    // TODO Auto-generated method stub
    webcam=Webcam.getDefault();
    webcam.setViewSize(new Dimension(640,480));
    webcam.open();
    new videoFeedback().start();
}
@FXML
public void dragged(MouseEvent event)
{
    Stage stage =(Stage)((Node)event.getSource()).getScene().getWindow();
    stage.setX(event.getScreenX()-x);
    stage.setY(event.getScreenY()-y);
}
@FXML
public void pressed(MouseEvent event)
{
    x=event.getSceneX();
    y=event.getSceneY();
}
@FXML
public void close(MouseEvent event)
{
    Stage stage =(Stage)((Node)event.getSource()).getScene().getWindow();
    stage.close();
    webcam.close();
}

@FXML
public void min(MouseEvent event)
{
    Stage stage =(Stage)((Node)event.getSource()).getScene().getWindow();
    stage.setIconified(true);
}

@FXML
void capture(ActionEvent event) throws IOException {
    BufferedImage image=webcam.getImage();
    Image im = SwingFXUtils.toFXImage(image, null);
    FXMLLoader loader=new FXMLLoader(selfiController.class.getResource("Demo.fxml"));
    AnchorPane an = (AnchorPane) loader.load();
    Controller secController=loader.getController();
    secController.setImage(im);
    webcam.close();
}

class videoFeedback extends Thread
{
    @Override
    public void run()
    {
        while(true)
        {
            try 
            {
                BufferedImage image=webcam.getImage();
                Image im = SwingFXUtils.toFXImage(image, null);
                videofeddback.setFill(new ImagePattern(im));
                Thread.sleep(40);
            }
            catch(Exception e)
            {

            }
        }
    }

}}
