Saving images after opening

Question

I have been having trouble finding a way to save images after I have them open into the program I am building. If anyone has an idea how to do this any info would be very much appreciated. Thanks

Answer 1

Heres a silly example:
import java.awt.Color;
import java.awt.Graphics2D;
import java.awt.geom.AffineTransform;
import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
import javax.swing.JOptionPane;

public class LoadAndSaveImage {
    public static void main(String[] args) throws Exception {
        BufferedImage bi = ImageIO.read(new File(args[0]));
        Graphics2D g2 = bi.createGraphics();
        g2.setColor(Color.RED);
        g2.setFont(g2.getFont().deriveFont(48f));
        g2.setTransform(AffineTransform.getRotateInstance(Math.PI/4));
        g2.drawString("I maded it better",48,48);
        g2.dispose();
        JLabel l = new JLabel(new ImageIcon(bi));
        javax.swing.JFrame f = new javax.swing.JFrame();
        f.setDefaultCloseOperation(f.EXIT_ON_CLOSE);
        f.getContentPane().add(l);
        f.pack();
        f.setVisible(true);
        if (JOptionPane.showConfirmDialog(f,"Should I save my excellent work?") == JOptionPane.OK_OPTION) {
            File out = new File("yourimagebutbetter.jpg");
            ImageIO.write(bi,"jpg",out);
            System.out.println("vandalized image saved at : " + out);
}Hopefully that will send you on your way.
I am new at this Then ignore my bad example of putting everything in main.
