// If an image is on the system clipboard, this method returns it;

Toolkit.getDefaultToolkit().getSystemClipboard().setContents(imgSel, null);
} // This class is used to hold an image while on the clipboard.
public static class ImageSelection implements Transferable {
private Image image; public ImageSelection(Image image) {
this.image = image;
} // Returns supported flavors
public DataFlavor[] getTransferDataFlavors() {
return new DataFlavor[]{DataFlavor.imageFlavor};
} // Returns true if flavor is supported
public boolean isDataFlavorSupported(DataFlavor flavor) {
return DataFlavor.imageFlavor.equals(flavor);
} // Returns image
public Object getTransferData(DataFlavor flavor) throws UnsupportedFlavorException, IOException {
if (!DataFlavor.imageFlavor.equals(flavor)) {
throw new UnsupportedFlavorException(flavor);
