Thread: java gui menu , saveing

hello , im trying to get my save function on my menu bar to work right. when i hit save on the menu bar , it creates the file and everything. but the picture is blank. i cant seem to find what i did wrong.


heres my save method, it supposed to save an image of my GUI canvas , but like i said i comes up blank.

 
public void SaveToDisk(String file) {
		file = "save.png";
		// need a buffered image to save the image
		BufferedImage bufferedImage = 
			new BufferedImage(150, 
					150, 
					BufferedImage.TYPE_INT_ARGB); 
 
 
		Graphics g = bufferedImage.createGraphics();
 
		this.paint(g);
 
 
		g.dispose();
 
 
		System.out.println("Saving file to disk:" + file); 
		try {
			ImageIO.write(bufferedImage, "png", new File(file));
		} catch (Exception e) {
			System.out.println("[e] cannot save");
		}		
	}
 
	public void loadImage() {
	      try {                
	    	  image = ImageIO.read(new File("save.png"));
	       } catch (IOException ex) {
	    	   System.out.println("[e] cannot load");
	       }
	}

just incase here the action listener for my save button , which im pretty sure is right

save.addActionListener(new ActionListener() {
 
			@Override
			public void actionPerformed(ActionEvent e) {
				System.out.println(e.getActionCommand());
				canvas.SaveToDisk("");
			}
 
		});
