Title Body

I have a JPanel with a painted background image and a layout manager holding other smaller images, all of this inside a JFrame . The background image is pretty big and I want to be able to have it maintain its aspect ratio whether its on a big or small monitor. Eventually, I want to be able to have my LayoutManager and the smaller images in its cells "glued" to the background picture. I looked around for resources and it seems that many examples use a BufferedImage but I am not; will this pose a problem? I'll post my code below for painting the image, If I lack any information please let me know. public class MonitorPanel extends JPanel { Image img; public MonitorPanel() throws MalformedURLException { //add components try { img = ImageIO.read(new File("src/customer_vlans.jpg")); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } protected void paintComponent(Graphics g) { //paint background image super.paintComponent(g); //g.drawImage(img, 0, 0, getWidth(), getHeight(), this); g.drawImage(img, 0, 0, this); } } EDIT: I should mention that I know the aspect ratio formula: original height / original width x new width = new height However, I do not know how to use that correctly to my advantage.
