java.awt.image.PixelGrabber (JDK 1.0)

This class is an ImageConsumer that extracts a specified rectangular array of pixels (in the default RGB color model) from a specified Image or ImageProducer and stores them into a specified array (using the specified offset into the array and specified scanline size). Use this class when you want to inspect or manipulate the data of an image or some rectangular portion of an image.

The method grabPixels() makes the PixelGrabber start grabbing pixels. status() returns the status of the pixel-grabbing process. The return value uses the same flag value constants as the ImageObserver class does. The remaining methods are the standard ImageConsumer methods and should not be called directly.
