When I run the following code it triggers an error message. The error message is shown below the code.

What code changes, or changes to the image file, are needed to fix this error?

Help will be appreciated.

import java.awt.*;
import java.awt.datatransfer.*;

public class LoadToClipboard {
    public static void main( String [] args ) {
      Toolkit tolkit = Toolkit.getDefaultToolkit();
      Clipboard clip = tolkit.getSystemClipboard();        
      clip.setContents( new ImageSelection( tolkit.getImage("StackOverflowLogo.png")) , null );
    }
}

class ImageSelection implements Transferable {
    private Image image;

    public ImageSelection(Image image) {
        this.image = image;
    }

    // Returns supported flavors
    public DataFlavor[] getTransferDataFlavors() {
        return new DataFlavor[]{DataFlavor.imageFlavor};
    }

    // Returns true if flavor is supported
    public boolean isDataFlavorSupported(DataFlavor flavor) {
        return DataFlavor.imageFlavor.equals(flavor);
    }

    // Returns image
    public Object getTransferData(DataFlavor flavor) throws UnsupportedFlavorException {
        if (!DataFlavor.imageFlavor.equals(flavor)) {
            throw new UnsupportedFlavorException(flavor);
        }
        return image;
    }
}

I have tried to find a place in the code where width and height can be specified, but have not succeeded. I also examined the properties of the jpg file and the w and h are specified.enter code here
