Question

Can anyone tell me : how to get BufferedImage of a JPanel

Answer 1

I've done something like this:
import java.awt.Graphics;
import java.awt.LayoutManager;
import java.awt.Dimension;
import java.awt.image.BufferedImage;
import java.io.InputStream;
import java.io.FileInputStream;
import javax.swing.JPanel;
import com.sun.image.codec.jpeg.JPEGCodec;
import com.sun.image.codec.jpeg.JPEGImageDecoder;

public class JBackgroundImagePanel extends JPanel {
     private BufferedImage mImage = null;
     private InputStream mImageStream = null;
     public  String mImageFilename = null;
     public JBackgroundImagePanel( String ImageFilename ) {
          super();
          mImageFilename = ImageFilename;
          initialize();
     public JBackgroundImagePanel( BufferedImage ImageFilename ) {
          super();
          mImage = ImageFilename;
          initialize();
     public JBackgroundImagePanel( InputStream ImageStream ) {
          super();
          mImageStream= ImageStream;
          initialize();
     private  void initialize() {
          if(mImage == null)
               try {
                    ClassLoader Loader = this.getClass().getClassLoader();
                    if( mImageStream == null )
                         mImageStream = Loader.getResourceAsStream(mImageFilename);
                         if( mImageStream == null )
                             mImageStream = new FileInputStream( mImageFilename );     
                    JPEGImageDecoder decoder = JPEGCodec.createJPEGDecoder( mImageStream );
                    mImage = decoder.decodeAsBufferedImage();
                    mImageStream.close();
               catch(Exception e){
                    System.out.print("Image could not be loaded in JBackgroundImagePanel.");
          this.setSize(mImage.getWidth(),mImage.getHeight());
     public void paintComponent(Graphics g) {
          super.paintComponent(g);
          g.drawImage(mImage, 0, 0, null);
}Hope this helps.
