Loading and displaying an image

Question

I have been able to do this with an applet quite easily
import java.applet.Applet;
import java.awt.Graphics;
import java.awt.Image;
// This is a simple example applet that loads an image and
// displays it.
public class DrawImage extends Applet
     Image image;
     public void init()
          image = getImage(getDocumentBase(), "cow1.jpg");
     public void paint(Graphics g)
          g.drawImage(image, 10, 10, this);
}I haven't been able to find a good source that explains how to do it just using swing and awt. The ones I have found are complicated or don't work. I am trying to program a tester program that will load an jpg image and redraw the panel then load another jpg image so it looks like its moving. I know you can do this just using the graphic in java but I would like to do it with a jpg image files. Can anyone help with simple code for this?

Answer 1

After lots of trial and error with certain classes and not knowing how to use certain methods correctly, I have this below code:
public class image_load extends Frame
     Image img;
     public static void main (String args[])
          Toolkit toolkit = Toolkit.getDefaultToolkit();
          img = toolkit.createImage("cow1.jpg");
          img = ImageIO.read();
          ImageIcon icon = new ImageIcon("cow1.jpg",
                                 "cow pic");
          JLabel label1 = new JLabel("Image and Text", icon, JLabel.CENTER);
          JFrame frame = new JFrame();
          //set frame to exit when closed
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.add(label1);     //add panel to frame
          frame.setSize(25,25);     //set size of frame to 300pix x300pix
          frame.setVisible(true);     //make frame visable
     public void paint(Graphics graphics) {
          graphics.drawImage(img, 0, 0, null);
}I get these errors from the code:
image_load.java:21: non-static variable img cannot be referenced from a static c
ontext
                img = toolkit.createImage("cow1.jpg");
                ^
image_load.java:23: non-static variable img cannot be referenced from a static c
ontext
                img = ImageIO.read();
                ^
image_load.java:23: cannot find symbol
symbol  : method read()
location: class javax.imageio.ImageIO
                img = ImageIO.read();
                             ^
3 errorsI have tried a contructor and other things. As for the imageIO.read error that only accepts in Buffered Images. For this I have this odd bit of code that needs changing to be able to work. Any more suggestions?
BufferedImage bufferedImage = new BufferedImage ( imageWidth,
                                                  imageHeight,
                                                  BufferedImage.TYPE_INT_BGR  );
          bufferedImage.createGraphics().drawImage( image, 0, 0, this);
