Thread: drawImage help! :(

I'm trying to draw an image inside a jScrollPane, or in any other scrollable type of panel... can someone please give me a VERY simple method as I'm new to java.. I have read all about jScrollPane on Oracle and about drawImage but can't find a way to do it ... :/ can someone please explain whats wrong?

BufferedImage img;
img = ImageIO.read(new File("C:\\apple.png"));
Graphics g = jScrollPane1.getGraphics();
g.drawImage(img, 0, 0, 100, 100, rootPane);

//I also tried to use paintComponents... but .. not successful.

It looks correct to me. What is the error message?

I don't get an image showing... the directory is good.. no error message.. it runs, but empty.. :s I've been trying for hours .. just frustrated heh.

I also tried to use paintComponents.

Remove the s from the method name.
Can you post the code where you override the paintComponent method of a JPanel and call drawImage there?

I wrote an article on Image processing a few months ago. It may be worth while checking out.

This is a stripped down version of the JPanel

 
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import javax.swing.JPanel;
import java.io.File;
import java.io.IOException;
import javax.imageio.*;
 
public class ImageJPanel extends JPanel {
 
public BufferedImage image;
 
public void loadImage(File imageFile) {
	try {
		image = ImageIO.read(imageFile);
	} catch (IOException ex) {
		String directory = new File(".").getAbsolutePath();
		System.err.println("Could not open " + imageFile.getAbsolutePath() + " at " + directory);
		System.exit(-1);
	}	
}
 
public void paintComponent(Graphics g)
{
    super.paintComponent(g);
    g.drawImage(image, 0, 0, null);  //draws the image
}
 
 
public ImageJPanel() {
        String filename = "myFile.jpg";
        File imageFile = new File(filename);
	loadImage(imageFile);
}

ChristopherLowe but then how do you put that into the JPanel you want? or how do you trigger it I tried adding for example:

ImageJPanel jPanelNew = new ImageJPanel();
jPanelNew.loadImage("C:\\apple.png");

also tried: jPanel1.add(jPanelNew); (in netbeans to get the things from that.. but nothing aswell)

and turned some things around so it does that but still nothing comes up :s.. am I calling it wrong? :s Iam using netbeans, and have a jPanel1 on the gui but.. have no idea how to declare it.. :s

IF you are getting error messages, please copy the full text and paste them here

You add the JPanel to a JFrame.
