<DL>
<DD>Constructs an <code>IndexColorModel</code> from an 
 <code>int</code> array where each <code>int</code> is 
 comprised of red, green, blue, and alpha            
 components in the default RGB color model format.  
 The array must have enough values in it to fill all
 of the needed component arrays of the specified size.
 The <code>ColorSpace</code> is the default sRGB space.  
 The transfer type is the smallest of
 DataBuffer.TYPE_BYTE, DataBuffer.TYPE_USHORT, or DataBuffer.TYPE_INT
 that can hold a single pixel.
 The <code>BigInteger</code> object specifies the valid/invalid pixels
 in the <code>cmap</code> array.  A pixel is valid if the 
 <code>BigInteger</code> value at that index is set, and is invalid
 if the <code>BigInteger</code> bit  at that index is not set.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>bits</CODE> - the number of bits each pixel occupies<DD><CODE>size</CODE> - the size of the color component array<DD><CODE>cmap</CODE> - the array of color components<DD><CODE>start</CODE> - the starting offset of the first color component<DD><CODE>transferType</CODE> - the specified data type<DD><CODE>validBits</CODE> - a <code>BigInteger</code> object.  If a bit is
    set in the BigInteger, the pixel at that index is valid.
    If a bit is not set, the pixel at that index
    is considered invalid.  If null, all pixels are valid.
    Only bits from 0 to map_size will be considered.</DL>
