Display Image using Java2D

One of the most important capabilities of Java2D API is to display image. An image is an array of pixels. Each pixel represents a color at a given position. We can use components like JLabel to display an image, or we can draw it using the Java 2D API.

Example :

Given below example will display image on panel :

package corejava;

import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Image;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class Java2DImage extends JPanel {
	public void paintComponent(Graphics g) {
		super.paintComponent(g);

		Graphics2D g2d = (Graphics2D) g;
		Image image = new ImageIcon(
				

"E:/ankit_tutorial/java/beautiful-nature-photographs.jpeg")
				.getImage();
		g2d.drawImage(image, 0, 0, null);
	}

	public static void main(String[] args) {

		Java2DImage image = new Java2DImage();
		JFrame frame = new JFrame("Java2D Image");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.add(image);
		frame.setSize(380, 320);
		frame.setLocationRelativeTo(null);
		frame.setVisible(true);
	}
