Saving an image in a png format

Question

Hi,
I am creating a simple applet for avatar-making. You can choose face, hair, eyes, etc and then save it to a disc as a png file. The simple version (without the interface for the simplicity purpose) looks like this:
import java.awt.*;
import java.applet.*;
import java.net.*;
public class Example extends Applet
     Image my_gif;
     Image my_gif2;
     URL base;
     MediaTracker mt;
     public void init()
            mt = new MediaTracker(this);
         try {
                 base = getDocumentBase();
         catch (Exception e) {}
           my_gif = getImage(base,"1.gif");
           my_gif2 = getImage(base,"2.gif");
           mt.addImage(my_gif,1);
           mt.addImage(my_gif2,2);
          try {
               mt.waitForAll();
          catch (InterruptedException  e) {}
     public void paint(Graphics g)
           g.drawImage(my_gif,0,0,this);
         g.drawImage(my_gif2,0,0,this);
}This example consists of two files. When run they are visible in a correct way. Now I would like to save it to a disc - I can save one image using BufferedImage but I want to "flatten" two or more images and save it. Any help would be greatly appreciated. I also agree that perhaps my approach is not the right one and would be grateful for any corrections.

Answer 1

If you can draw what you want out to the screen properly, then do the same thing to a BufferedImage's GraphicsContext, once you have the BufferedImage, then use ImageIO to write your image to a file.
