<DL>
<DD>Returns the number of bits for the specified color/alpha component.
 Color components are indexed in the order specified by the 
 <code>ColorSpace</code>.  Typically, this order reflects the name
 of the color space type. For example, for TYPE_RGB, index 0
 corresponds to red, index 1 to green, and index 2
 to blue.  If this <code>ColorModel</code> supports alpha, the alpha
 component corresponds to the index following the last color
 component.<DD><DL>

 An <code>IllegalArgumentException</code> thrown if pixel values
 for this <code>ColorModel</code> are not conveniently representable

getRed</H3>
<PRE>
public int <B>getRed</B>(<A HREF="../../../java/lang/Object.html">Object</A>&nbsp;inData)</PRE>
<DL>
<DD>Returns the red color component for the specified pixel, scaled
 from 0 to 255 in the default RGB <code>ColorSpace</code>, sRGB.  A
 color conversion is done if necessary.  The pixel value is
 specified by an array of data elements of type transferType passed
 in as an object reference.  The returned value is a non
 pre-multiplied value.  For example, if alpha is premultiplied,
 this method divides it out before returning
 the value.  If the alpha value is 0, the red value is 0.
 If <code>inData</code> is not a primitive array of type
 transferType, a <code>ClassCastException</code> is thrown.  An
 <code>ArrayIndexOutOfBoundsException</code> is thrown if 
 <code>inData</code> is not large enough to hold a pixel value for
 this <code>ColorModel</code>.
 If this <code>transferType</code> is not supported, a       
 <code>UnsupportedOperationException</code> will be
 thrown.  Since
 <code>ColorModel</code> is an abstract class, any instance
 must be an instance of a subclass.  Subclasses inherit the
 implementation of this method and if they don't override it, this
 method throws an exception if the subclass uses a
 <code>transferType</code> other than
 <code>DataBuffer.TYPE_BYTE</code>,
