getBlue</H3>
<PRE>
public int <B>getBlue</B>(<A HREF="../../../java/lang/Object.html">Object</A>&nbsp;inData)</PRE>
<DL>
<DD>Returns the blue 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 <CODE>pixel</CODE> value is 
 specified by an array of data elements of type <CODE>transferType</CODE> 
 passed in as an object reference. The returned value is a non pre-multiplied 
 value. If the alpha is premultiplied, this method divides it out before
 returning the value (if the alpha value is 0, the blue value will be 0).
 Since <code>ComponentColorModel</code> can be subclassed,
 subclasses inherit the implementation of this method and if they
 don't override it then they throw an exception if they use an
 unsupported <code>transferType</code>.<DD><DL>
