PIXRANGE
Type: Adverb  (Array(2))
Use:   Range of image values used for various tasks and verbs.
       The first element represents a minimum value and the
       second element represents a maximum value.  The units
       are the same as those of the image.  The values may
       exceed the values in the image up to a fairly extreme
       limit.  If, for example, PIXRANGE(2) > 100 * map max,
       however, the map max is used as PIXRANGE(2).
Null Value:  (0,0)
       Null value assignment usually map min to map max.
       PIXRANGE(2) <= PIXRANGE(1) taken as "null value".
