BufferedImage to System Clipboard

[Gregg Bolinger]

Does anyone know how to transfer a BufferedImage to the System Clipboard? Or if it is even possible?

[Nathan Pruett]

Yep... it's possible...

public class ClipboardImage implements ClipboardOwner {
    public ClipboardImage() {
        try {
            Robot robot = new Robot();
            Dimension screenSize  = Toolkit.getDefaultToolkit().getScreenSize();
            Rectangle screen = new Rectangle( screenSize );
            BufferedImage i = robot.createScreenCapture( screen );
            TransferableImage trans = new TransferableImage( i );
            Clipboard c = Toolkit.getDefaultToolkit().getSystemClipboard();
            c.setContents( trans, this );
        }
        catch ( AWTException x ) {
            x.printStackTrace();
            System.exit( 1 );
        }
    }
    
    public static void main( String[] arg ) {
        ClipboardImage ci = new ClipboardImage();
    }
        
    public void lostOwnership( Clipboard clip, Transferable trans ) {
        System.out.println( "Lost Clipboard Ownership" );
    }
    
    private class TransferableImage implements Transferable {
        
        Image i;
        
        public TransferableImage( Image i ) {
            this.i = i;
        }
        
        public Object getTransferData( DataFlavor flavor ) 
        throws UnsupportedFlavorException, IOException {
            if ( flavor.equals( DataFlavor.imageFlavor ) && i != null ) {
                return i;
            }
            else {
                throw new UnsupportedFlavorException( flavor );
            }
        }
        
        public DataFlavor[] getTransferDataFlavors() {
            DataFlavor[] flavors = new DataFlavor[ 1 ];
            flavors[ 0 ] = DataFlavor.imageFlavor;
            return flavors;
        }
        
        public boolean isDataFlavorSupported( DataFlavor flavor ) {
            DataFlavor[] flavors = getTransferDataFlavors();
            for ( int i = 0; i < flavors.length; i++ ) {
                if ( flavor.equals( flavors[ i ] ) ) {
                    return true;
                }
            }
            
            return false;
        }
    }
}
