Level 2 Help for MAXMIN

Name of a single input file.

Name of a single output file.

The size parameter determines the boundaries in the input
file from which the MAXMIN is to take place.  It is specified
as  (SL,SS,NL,NS), where
	SL is the starting line 
	SS is the starting sample
	NL is the number of lines to be copied
	NS is the number of samples (pixels) in each line

The bands parameter determines the bands in the input
file from which the MAXMIN is to take place.  It is specified
as (SB,NB), where
	SB is the starting band
	NB is the number of bands to be copied

The execution time of MAXMIN can be reduced by specifying a LINC parameter
value greater than 1.  In this case, only one out of every LINC lines
in the image is examined.  This may produce acceptable results if the image
data is fairly continuous and if an approximate minimum and maximum are
acceptable.  The default for LINC is 1.

An EXCLUDE value can be specified to exclude a particular value in the
search for the minimum and maximum.   The EXCLUDE parameter is a REAL*4 value,
and is rounded to the nearest integer for images with integral pixel values.
For images of the complex data type, EXCLUDE is REAL*4, and it is the 
magnitudes of the pixel values that are compare against EXCLUDE.

In MAXMIN, the minimum and maximum are set to EXCLUDE if all of
the values in the image are equal to EXCLUDE.  (That would be a flat image.)

The default is to not exclude any values

MAXMIN optionally returns the minimum pixel value (DN) in the image into
a TCL variable (of type real).  The command line syntax for this parameter
is MINIVAL=var1, where 'var1' represents the TCL variable of type real
in which the minimum value is returned.
The minimum value is returned if and only if this parameter is specified.

MAXMIN optionally returns the maximum pixel value (DN) in the image into
a TCL variable (of type real).  The command line syntax for this parameter
is MAXIVAL=var1, where 'var1' represents the TCL variable of type real
in which the maximum value is returned.
The maximum value is returned if and only if this parameter is specified.
