【问题描述】:
我试图从文件系统加载图像,但我没有错误并且不显示图像。图片的文件位于 Package 文件夹 ../src/application/a.png 中,我尝试以不同的方式加载图片,如下所示:
图像 image = new Image("file:a.png");
Image image = new Image(new File("a.png").toURI().toString());
package application;
import java.io.File;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.effect.ColorAdjust;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage stage) {
Image image = new Image(new File("/a.png").toURI().toString());
// Setting the image view
ImageView imageView = new ImageView(image);
// Setting the position of the image
imageView.setX(0);
imageView.setY(0);
// setting the fit height and width of the image view
imageView.setFitHeight(200);
imageView.setFitWidth(400);
// Setting the preserve ratio of the image view
imageView.setPreserveRatio(true);
// Creating a Group object
Group root = new Group(imageView);
// Creating a scene object
Scene scene = new Scene(root, 600, 300);
// Setting title to the Stage
stage.setTitle("Coloradjust effect example");
// Adding scene to the stage
stage.setScene(scene);
// Displaying the contents of the stage
stage.show();
}
public static void main(String args[]) {
launch(args);
}
}
