Cannot Load Image in Javafx

Cannot load image in JavaFX

Simply replace this code:

Image img = new Image("logo.png");

with this

Image img = new Image("file:logo.png");

Docu reference.
https://docs.oracle.com/javase/8/javafx/api/javafx/scene/image/Image.html

When you pass a String to the Image class it can be handled in four different ways (copied from docu):

// The image is located in default package of the classpath
Image image1 = new Image("/flower.png");

// The image is located in my.res package of the classpath
Image image2 = new Image("my/res/flower.png");

// The image is downloaded from the supplied URL through http protocol
Image image3 = new Image("http://sample.com/res/flower.png");

// The image is located in the current working directory
Image image4 = new Image("file:flower.png");

The file: prefix is simply an URI scheme, or in other words the counterpart to the http: protocol classifier. This also works in the file browser, or in the web browser... ;)

For further reference, you can take a look at the wiki page of the file URI scheme: https://en.wikipedia.org/wiki/File_URI_scheme

Happy Coding,

Javafx can't load new added image

This works for me.

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class FxTemp extends Application {

    public static void main(String[] args){
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        Image image = new Image("file:///home/username/Desktop/test.png");
        primaryStage.setTitle("animated");
        ImageView imageView = new ImageView(image);
        imageView.addEventHandler(MouseEvent.MOUSE_CLICKED, evt->{
            System.out.println("click");
            Image imager = new Image("file:///home/username/Desktop/test.png");
            imageView.setImage(imager);
        });
        StackPane root = new StackPane();
        root.getChildren().add(imageView);
        primaryStage.setScene(new Scene(root, 512, 512));
        primaryStage.show();
    }
}

If I change the test.png and click on the view, I see the new image.

You're not really supposed to be added files to your 'resources', those are files you provide before execution. Intellij will copy the files to a location and use that location on your class path. Then you can access them via getResource.

If you're going to have a folder that you add files to, then you want to access those files, you can do something like.

String nextImage = new File("./res/image.png").toURI().toString();

Then you should be able to load your new image provided your path is correct.
