Question

I have the following snippet that loads the images:

    String imgName = "/assets/" + name;
    URL imgURL = Groovy.class.getResource(imgName);
            System.out.println(imgURL.getPath());
    Toolkit tk = Toolkit.getDefaultToolkit();
    Image image = tk.getImage(imgURL);
    return image;

And where the image is drawn:

        Graphics2D g = (Graphics2D) strategy.getDrawGraphics();
        g.setColor(Color.black);
        g.fillRect(0,0,screenWidth,screenHeight);
        g.drawImage(background, 0, 0, null);
        System.out.println(background.getWidth(null));
        if (background.getWidth(null) < 0)
            System.exit(1);

However imgURL always returns null. I’m using Eclipse (and fresh to it, blegh), and running the classes with run or debug option. If I change the path, it gives a file not found exception.

File structure is as followed:

Project -> src and assets -> src has Groovy, assets has image -> Groovy has Groovy.class

Edit: I switched back to Netbeans. The imgURL is now loading fine and getPath returns it’s correct path. However the image width / height return -1. This is the actual problem now.

Edit: -1 means that the width is not yet known, however displaying the image shows a white screen.

Answer 1

The problem resided in the use the toolkit to get the image, possibly because I’m using OpenJDK? Anyway, using ImageIO.read(imgURL) fixed this.
