<DL>
<DD>Constructs a <CODE>ComponentColorModel</CODE> from the specified 
 parameters. Color components will be in the specified 
 <CODE>ColorSpace</CODE>.  The <CODE>bits</CODE> array specifies the 
 number of significant bits per color and alpha component.  Its
 length should be the number of components in the 
 <CODE>ColorSpace</CODE> if there is no alpha 
 information in the pixel values, or one more than this number if 
 there is alpha information.  An <CODE>IllegalArgumentException</CODE> 
 is thrown if the length of the array does not match the number of 
 components.  <CODE>hasAlpha</CODE> indicates whether alpha
 information is present.  If <CODE>hasAlpha</CODE> is true, then 
 the boolean <CODE>isAlphaPremultiplied</CODE> 
 specifies how to interpret color and alpha samples in pixel values.  
 If the boolean is true, color samples are assumed to have been 
 multiplied by the alpha sample. The <CODE>transparency</CODE> 
 specifies what alpha values can be represented by this color model.
 The acceptable <code>transparency</code> values are
 <CODE>OPAQUE</CODE>, <CODE>BITMASK</CODE> or <CODE>TRANSLUCENT</CODE>.
  The <CODE>transferType</CODE> is the type of primitive array used
 to represent pixel values.  Note that the <CODE>bits</CODE> array
 contains the number of significant bits per 
 color/alpha component after the translation from pixel values.<DD><DL>

<DL>
<DD>Returns the red color component for the specified pixel, scaled

 it out before returning the value (if the alpha value is 0,
 the red value will be 0).<DD><DL>
