示例1: createVolatileImage

import java.awt.peer.ComponentPeer; //导入方法依赖的package包/类
/**
 * Creates a volatile off-screen drawable image
 *     to be used for double buffering.
 * @param     width the specified width.
 * @param     height the specified height.
 * @return    an off-screen drawable image, which can be used for double
 *    buffering.  The return value may be <code>null</code> if the
 *    component is not displayable.  This will always happen if
 *    <code>GraphicsEnvironment.isHeadless()</code> returns
 *    <code>true</code>.
 * @see java.awt.image.VolatileImage
 * @see #isDisplayable
 * @see GraphicsEnvironment#isHeadless
 * @since     1.4
