Here's a simple example for displaying a BufferedImage:
import java.awt.Color;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class BufferedImageTest {
public static void main(String[] args) {
try {
JFrame frame = new JFrame();
BufferedImage image = new BufferedImage(300, 300, BufferedImage.TYPE_INT_RGB);
Graphics g = image.createGraphics();
g.setColor(Color.WHITE);
g.fillRect(0, 0, image.getWidth(), image.getHeight());
g.setColor(Color.BLUE);
g.drawRect(50, 50, 200, 200);
g.dispose();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(new JLabel(new ImageIcon(image)));
frame.pack();
frame.setVisible(true);
} catch (Exception e) {e.printStackTrace();}
}
}
