Invoked by Swing to draw components.

Usage

From source file:Utils.java

/** 
 * Renders a component into an image, which is useful for playing with the component's 
 * resultant image in special effects or transitions
 *
 * @param component The component to render
 * @return A buffered image with the rendered component. 
 *//*from w w w  . j av  a 2s.c o m*/
public static BufferedImage renderComponentToImage(JComponent component) {
    //Create the image
    BufferedImage image = createCompatibleImage(component.getWidth(), component.getHeight());

    //Render the component onto the image
    Graphics graphics = image.createGraphics();
    //      component.update(graphics);
    component.paint(graphics);
    graphics.dispose();
    return image;
