How to resize image to maximize their dimensions into a panel without changing aspect ratio

Question

I want to draw some images into a panel, I need that the images conserves their aspect ratio with the biggest dimensions to be drawn over a panel. So given the panel dimensions I must create a Java code to maximize that dimensions. The only ideas that I had needed to solve some linear programming, and I don't know how to do it in Java. Which should be the easiest way to do what I need?

Answer 1

Here is the method to get a re-sized BufferedImage.

private BufferedImage resizeImage(BufferedImage originalImage, int width, int height)
        throws IOException {
    BufferedImage resizedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
    Graphics2D g = resizedImage.createGraphics();
    g.drawImage(originalImage, 0, 0, width, height, null);
    g.dispose();
    return resizedImage;
}
