Well, that's what you're telling to do (stay the original size, that is).
Try looking at the API docs for BufferedImage (and Graphics2D) and see if there is something there that can help you.

No one told you to override paintComponent.
Load the image into a BufferedImage, get the Graphics2D, modify it, then create a ImageIcon from that.

You should be overriding paintComponent(), not paint(), in your "NewClass" class.
(And find a new name for that class because NewClass is an awful name for a component)

hay man It solved by following code it not works because Paint method not initialized public class NewJFrame extends javax.swing.JFrame {
LoadImg imgobj;
Container con;
/** Creates new form NewJFrame */
public NewJFrame() {
initComponents();
//Pan1 obj=new Pan1();]
BufferedImage bimg = null;
try
{
// Track the image to completion.
bimg = ImageIO.read(new File("D:\\Books\\1.jpg"));
JPanel cont = (JPanel) getContentPane();
//cont.setLayout(new BorderLayout());
imgobj = new LoadImg(bimg);
imgobj.setBounds(50,100, 200, 200);
cont = new NewClass(bimg);
imgobj.setImage(bimg);
Image img = imgobj.getImage(bimg);
imgobj.prepareImage(imgobj.getImage(bimg), this.getHeight(),this.getWidth(), null);
System.out.println("Image Readed...");
getContentPane().add(imgobj,BorderLayout.CENTER);
}
catch(Exception e)
{
System.out.println("the error in frame..."+e);
}
}
}
class LoadImg extends JPanel implements Serializable {
Image image = null;
public LoadImg() {
}
public LoadImg(Image image) {
this.image = image;
System.out.println("Class Panel Constructed...");
}
public void LoadImg(Image image){
this.image = image;
System.out.println("Image set...");
}
public Image LoadImg(Image image){
return image;
}
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g); //paint background
if (image != null) { //there is a picture: draw it
int height = this.getSize().height;
int width = this.getSize().width;
g.drawImage(image,0,0, width, height, this);
System.out.println("paint Component method ...");
//g.drawImage(image, 0, 0, this); //original image size
} //end if
} //end paint
} //end classBut now i want to chang Image at runtime
fetching record to database at runtime. but the image can't drown
