VALUE=I The DN value "I" is used to specify
the primary DN value of the binary
mask. All values listed in the
QTABLE list will be stretched to
"I" DN.
BVALUE=J The Dn value "J" is used to specify
the background Dn value of the
binary mask. All values not listed
in the QTABLE list will be
stretched to "J" DN if BVALUE is
specified; otherwise the values are
not changed.
QTABLE= The QTABLE keyword is used to
(N1,N2, denote a list of DN values "N1 to
N3,... Nn" which are to be stretched to
Nn) the primary DN value "I" (see
VALUE). The sequence of DN values
is not restricted to any numerical
order. All values not listed with
QTABLE will be stretched to the
background BVALUE if specified, or
unchanged if BVALUE is defaulted.
TABLE= The TABLE keyword is used to denote
(01,N1, all input values "01 to 0n" to be
02,N2 stretched to corresponding output
... values "N1 to Nn". Data is entered
01,N1 as pairs 01,N1 where 01 denotes an
... old DN value to be stretched to a
On,Nn) new DN value, N1. ONLY THOSE DN
VALUES LISTED WILL BE STRETCHED,
AND ALL VALUES NOT LISTED WILL
REMAIN UNCHANGED. The order of
stretch pairs 01,N1 are not
restricted to any specific
numerical order.
