Thanks Michael,
On my paintComponent function I am doing like this...
Here
Image img;
ImagePlus implus;
Public void paintComponent(Graphicd g)
{
if (implus == null)
{
return;
}
img = null;
//getting current image from imageplus
img = implus.getImage();
if (img != null)
{
g.drawImage(img, drawx, drawy, drawx1, drawy1, null);
}
}
After any change in window level I call below method.
implus.updateImage();
repaint();
thanks

Hi,
to me it looks like a problem with the
public void paint(Graphics g)
method of your viewer. Probably it does not paint the image (g.drawImage)
except on the first call, so any repaint operation will leave it white.
E.g., do you have the bufferedImage in a class variable, so that it
remains accessible in a separate (repaint) thread)?
Michael
