Public Function Threshold( _
   ByVal Min As Single, _
   ByVal Max As Single _
) As DicomLabel

The DicomLabel to which this method is applied must be of a type which defines an area, i.e. doLabelRectangle, doLabelEllipse, doLabelPolygon, or doLabelBitmap.
The result is a new label (unattached to any collection) of type doLabelBitmap, which consists of all those points in the original label whose values (after applying scaling if necessary) fall with the range Min to Max inclusive.
