示例1: checkImage
import java.awt.peer.ComponentPeer; //导入方法依赖的package包/类
/**
* Returns the status of the construction of a screen representation
* of the specified image.
* <p>
* This method does not cause the image to begin loading. An
* application must use the <code>prepareImage</code> method
* to force the loading of an image.
* <p>
* The <code>checkImage</code> method of <code>Component</code>
* calls its peer's <code>checkImage</code> method to calculate
* the flags. If this component does not yet have a peer, the
* component's toolkit's <code>checkImage</code> method is called
* instead.
* <p>
* Information on the flags returned by this method can be found
* with the discussion of the <code>ImageObserver</code> interface.
* @param image the <code>Image</code> object whose status
* is being checked
* @param width the width of the scaled version
* whose status is to be checked
* @param height the height of the scaled version
* whose status is to be checked
* @param observer the <code>ImageObserver</code> object
* to be notified as the image is being prepared
* @return the bitwise inclusive <b>OR</b> of
* <code>ImageObserver</code> flags indicating what
* information about the image is currently available
* @see #prepareImage(Image, int, int, java.awt.image.ImageObserver)
* @see Toolkit#checkImage(Image, int, int, java.awt.image.ImageObserver)
