Save Image to system's ClipBoard .PLEASE HELP!!!!!

Question

Hi,
I'm trying to save an Image from my GUI to the System's ClipBoard but I just can't get it to work.
I've overriden a JPanel's paint() method where I draw my own stuff.
I've used the following code which I found in the forum :
class ImageSelection implements Transferable,ClipboardOwner
private DataFlavor ImageFlavor;
private DataFlavor[] flavors = new DataFlavor[1];
private Image image;
public ImageSelection(Image an_image)
this.image = an_image;
try
ImageFlavor = new DataFlavor(Class.forName("java.awt.Image"),"AWT Image");
flavors[0] = ImageFlavor;
catch(ClassNotFoundException e)
e.printStackTrace();
public synchronized DataFlavor[] getTransferDataFlavors()
return flavors;
public boolean isDataFlavorSupported(DataFlavor flavor)
return flavor.equals(ImageFlavor);
public synchronized Object getTransferData(DataFlavor flavor) throws UnsupportedFlavorException, IOException
if(flavor.equals(ImageFlavor))
return image;
else throw new UnsupportedFlavorException(flavor);
public void lostOwnership(Clipboard c, Transferable t)
When I want to save my Graphics into the clipboard I do the following:
ImageSelection temp = new ImageSelection(my_graphics.offImage);
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
clipboard.setContents(temp,temp);
You may also need the following :
class My_Stuff extends JPanel
Graphics2D offGraphics2D = null;
Image offImage = null;
void init_graphics()
offImage = this.createImage(100,100);
offGraphics2D = offImage.getGraphics();
void paint(Graphics g)
Graphics2D g2 = (Graphics2D)g;
offGraphics2D.fillRect(0,0,200,200);
// bla bla bla .........................
g2.drawImage(offImage,0,0,null);
and finally : My_Stuff my_graphics = new My_Stuff();
As you observe variable my_graphics is of type My_Stuff , so I pass its field : offImage , as the argument for the ImageSelection 's Constructor which in turn expects an Image...
I am "saving" the Image to the system's ClipBoard and I try to Paste it in MS Word but the 'Paste' feature is inactive ( I guess Clipboard is empty... )
Can you please help me out in this one???
I use JDK 1.4.0 and Win2000.
Thank you my friends!

If you use JDK1.4, simply use DataFlavor.imageFlavor insteads
of your own. Java will do the rest. Word cannot paste because
it does not recognise the flavor you put on the clipboard!
You can use this code that does it fine for me (JDK1.4.1)!
public class ImageSelection implements Transferable
private java.awt.Image image;
public ImageSelection(Image i) {
image = i;
public Object getTransferData(DataFlavor flavor)
throws UnsupportedFlavorException
if (flavor.equals(DataFlavor.imageFlavor)) {
return image;
throw new UnsupportedFlavorException(flavor);
public boolean isDataFlavorSupported(DataFlavor flavor) {
if (flavor.equals(DataFlavor.imageFlavor)) {
return true;
return false;
public DataFlavor[] getTransferDataFlavors() {
return new DataFlavor[] {DataFlavor.imageFlavor};
}
