Paints this component.

Usage

From source file:Main.java

public static Image getImage(Component c) {
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice gd = ge.getDefaultScreenDevice();
    GraphicsConfiguration gc = gd.getDefaultConfiguration();

    // Create an image that supports transparent pixels
    BufferedImage bImage = gc.createCompatibleImage(c.getWidth(), c.getHeight(), Transparency.BITMASK);

    /*/*w ww  .  j av a 2s .  co m*/
     * And now this is how we get an image of the component
     */
    Graphics2D g = bImage.createGraphics();

    // Then use the current component we're in and call paint on this
    // graphics object
    c.paint(g);
    return bImage;
