Hi All,

Thanks you for your kind suggesstions.
We tried as you said in yesterday's mail. We tried to
create a thread in the captureDialog() method, and in
that method convertGridToImage(File f) is called.
     We are able to create a jpeg file of the grid
but, the entire grid is not saved. We have a 6 X 11
grid. Only the Bottom line of the grid is saved and is
visible as jpeg file. We are not able to see the whole
grid.
      Our application generates whole grid using VisAD
and it is fully visible as 6 X 11 grid.But when it is
saved as jpeg file only bottom line is visible. Please
help us.

public  void convertGridToImage(File f) throws
FileNotFoundException, IOException, RemoteException,
VisADException {
        BufferedImage image = display.getImage();
        FileOutputStream fout;
        try {
            JPEGEncodeParam param
JPEGCodec.getDefaultJPEGEncodeParam(image);
            param.setQuality(100, true);
            fout = new FileOutputStream(f);
            JPEGImageEncoder encoder
JPEGCodec.createJPEGEncoder(fout);
            encoder.encode(image, param);
           fout.close();
        } 
        catch (NoClassDefFoundError err) {
            throw new VisADException("JPEG codec not
found");
        }
        
    } 
    
    public void captureDialog() throws VisADException,
RemoteException{
        final File f = new File("c:/jpegfile.jpeg");
        if (f == null) return;
        Runnable captureImage = new Runnable() {
            public void run() {
                String msg = "Could not save image
snapshot to file \"" + f.getName() +
                "\" in JPEG format. ";
                try {
                    convertGridToImage(f);
                }
                catch (VisADException exc) {
                    System.out.println("Error in image
saving");
                  
                }
                catch (IOException exc) {
                    System.out.println("Error in image
saving");
                
                }
            }
        };
        Thread t = new Thread(captureImage);
        t.start();
    }

=====================================================

with regards,
Karan Kapoor.
