Examples of java.awt.image.PixelGrabber.grabPixels()

java.awt.image.PixelGrabber.grabPixels()
Request the Image or ImageProducer to start delivering pixels and wait for all of the pixels in the rectangle of interest to be delivered. @return true if the pixels were successfully grabbed, false onabort, error or timeout @exception InterruptedException Another thread has interrupted this thread.

   * @return <code>true</code> of <code>false</code>, according to the result
