public int <B>getHeight</B>()</PRE>
<DL>
<DD>Get the height of the pixel buffer (after adjusting for image height).
 If no width was specified for the rectangle of pixels to grab then
 then this information will only be available after the image has
 delivered the dimensions.<DD><DL>

 is not yet known<DT><B>See Also: </B><DD><A HREF="../../../java/awt/image/PixelGrabber.html#getStatus()"><CODE>getStatus()</CODE></A></DL>

getPixels</H3>
<PRE>
public <A HREF="../../../java/lang/Object.html">Object</A> <B>getPixels</B>()</PRE>
<DL>
<DD>Get the pixel buffer.  If the PixelGrabber was not constructed
 with an explicit pixel buffer to hold the pixels then this method
 will return null until the size and format of the image data is
 known.
 Since the PixelGrabber may fall back on accumulating the data
 in the default RGB ColorModel at any time if the source image
 uses more than one ColorModel to deliver the data, the array
 object returned by this method may change over time until the
 image grab is complete.<DD><DL>

<PRE>
public <A HREF="../../../java/awt/image/ColorModel.html">ColorModel</A> <B>getColorModel</B>()</PRE>
<DL>
<DD>Get the ColorModel for the pixels stored in the array.  If the
 PixelGrabber was constructed with an explicit pixel buffer then
 this method will always return the default RGB ColorModel,
 otherwise it may return null until the ColorModel used by the
 ImageProducer is known.
 Since the PixelGrabber may fall back on accumulating the data
 in the default RGB ColorModel at any time if the source image
 uses more than one ColorModel to deliver the data, the ColorModel
 object returned by this method may change over time until the
 image grab is complete and may not reflect any of the ColorModel
 objects that was used by the ImageProducer to deliver the pixels.<DD><DL>
