<H4>NBIT</H4>
<PRE>
  Valid Values:   1 &lt;= x &lt;= 8
  Default:        6
</PRE>
Specifies the number of high-order bits used per byte of data in
constructing the histogram table. The default of 6 is recommended
for normal 8-bit data. Note that in general, using more bits per
byte does not correspond to increased accuracy; instead, it may make
the clustering unstable.
