<DD>Constructs a <code>DirectColorModel</code> from the specified masks 
 that indicate which bits in an <code>int</code> pixel representation 
 contain the red, green and blue color samples.  As pixel values do not
 contain alpha information, all pixels are treated as opaque, which
 means that alpha&nbsp;=&nbsp;1.0.  All of the bits
 in each mask must be contiguous and fit in the specified number
 of least significant bits of an <code>int</code> pixel representation.
  The <code>ColorSpace</code> is the default sRGB space. The

<DD>Constructs a <code>DirectColorModel</code> from the specified masks

 contain the red, green and blue color samples and the alpha sample, 
 if present.  If <code>amask</code> is 0, pixel values do not contain

<DL>
<DD>Constructs a <code>DirectColorModel</code> from the specified
 parameters.  Color components are in the specified 
 <code>ColorSpace</code>, which must be of type ColorSpace.TYPE_RGB.
 The masks specify which bits in an <code>int</code> pixel 
 representation contain the red, green and blue color samples and
 the alpha sample, if present.  If <code>amask</code> is 0, pixel
 values do not contain alpha information and all pixels are treated 
 as opaque, which means that alpha&nbsp;=&nbsp;1.0.  All of the
 bits in each mask must be contiguous and fit in the specified number
 of least significant bits of an <code>int</code> pixel 
 representation.  If there is alpha, the <code>boolean</code>
 <code>isAlphaPremultiplied</code> specifies how to interpret
 color and alpha samples in pixel values.  If the <code>boolean</code>
 is <code>true</code>, color samples are assumed to have been
 multiplied by the alpha sample.  The transparency value is
 Transparency.OPAQUE, if no alpha is present, or
 Transparency.TRANSLUCENT otherwise.  The transfer type
 is the type of primitive array used to represent pixel values and
 must be one of DataBuffer.TYPE_BYTE, DataBuffer.TYPE_USHORT, or
 DataBuffer.TYPE_INT.<DD><DL>
