How to save an image in a set location?

I am trying to save a resized picture to the user's desktop but not sure how to do that.

Here's my code so far:

mi.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            String userhome = System.getProperty("user.home");
            fileChooser = new JFileChooser(userhome + "\\Desktop");
            fileChooser.setAutoscrolls(true);
            switch (fileChooser.showOpenDialog(f)) {
            case JFileChooser.APPROVE_OPTION:
                BufferedImage img = null;
                try {
                    img = ImageIO.read(fileChooser.getSelectedFile());
                } catch (IOException e1) {
                    e1.printStackTrace();
                }
                Image dimg = img.getScaledInstance(f.getWidth(),
                        f.getHeight(), Image.SCALE_SMOOTH);

                path = new ImageIcon(dimg);
                configProps.setProperty("Path", fileChooser
                        .getSelectedFile().getPath());
                imBg.setIcon(path);

                break;
            }
        }
    });

The code above resizes the imaged selected to fit the size of the JFrame then sets it to the JLabel.

This all works well but I also want to output the file to a set location lets say to the users desktop to make it easier. I'm currently looking at output stream but can't quite get my head around it.

Any help would be great.

Solution

Get the current Icon from the JLabel...

Icon icon = imgBg.getIcon();

Paint the icon to a BufferedImage...

BufferedImage img = new BufferedImage(icon.getIconWidth(), icon.getIconHeight(), BufferedImage.TYPE_INT_ARGB);
Graphics2D g2d = img.createGraphics();
icon.paintIcon(null, g2d, 0, 0);
g2d.dispose();

Save the image to a file...

ImageIO.write(img, "png", new File("ResizedIcon.png"));

(and yes, you could use a JFileChooser to pick the file location/name)

You should also take a look at this for better examples of scaling an image, this way, you could scale the BufferedImage to another BufferedImage and save the hassle of having to re-paint the Icon
