+          Processing this record will enable Offset and Scale calculations, and set the Offset=-min(Array)
+          and Scale=MaxScale/(max(Array)-min(Array)), where MaxScale is the maximum value
+          of the output data type. The output array will thus be scaled to completely fill
+          the range of the output data type. Note that the calculation of the offset and scale
+          factors is only done once when this record is processed, and these values are used
+          for subsequent array callbacks, i.e. it does not autoscale on each array callback.
+          Thanks to Tom Cobb for this addition.
