Display Image on JDesktopPane

In this section, you will learn how to retrieve an image from the database and display it on the JDesktopPane. You can see in the given example, we have retrieved an image in the form of bytes and the method createImage() get these bytes and allowed the retrieved image to be displayed on the JDesktoPane.

Here is the code:

import java.sql.*;
import java.awt.*;
import javax.swing.*;

public class RetrieveImage {
	public static void main(String argv[]) {
		try {
			Class.forName("com.mysql.jdbc.Driver").newInstance();
			Connection con = DriverManager.getConnection(
					"jdbc:mysql://localhost:3306/test", "root", "root");
			Statement stmt = con.createStatement();
			ResultSet rs = stmt
					.executeQuery("select image from image where image_id='3'");
			byte[] bytes = null;
			if (rs.next()) {
				bytes = rs.getBytes(1);
			}
			rs.close();
			stmt.close();
			con.close();
			if (bytes != null) {
				JFrame f = new JFrame();
				f.setTitle("Display Image From database");
				Image image = f.getToolkit().createImage(bytes);
				f.getContentPane().add(new Pane(image));
				f.setSize(300, 100);
				f.setVisible(true);
			}
		} catch (Exception e) {
		}
	}
}

class Pane extends JDesktopPane {
	private Image image;

	public Pane(Image image) {
		this.image = image;
	}

	public void paintComponent(Graphics g) {
		super.paintComponent(g);
		g.drawImage(image, 0, 0, this);
	}
}

Output:

In this tutorial you learned how to display image on JDesktopPane in a Swing application.
