ParmDescription
FROM
File name for image to be listed.
EX:  DU5:IMAGE.PIC
PAGE
List the DN values on one listed output page.  The entire
image is shown by displaying only occasional lines and
samples so that it will fit on a page.  Fifty lines will
fit on one page of print out and the number of samples
is dependent on the bit type; 8 bit = 25, 16 bit = 20, 32
bit = 10. For instance a 1000 by 1000 8 bit image would
display one line in every 20 and one sample in every 40.
This option should only be used when the entire image is
to be listed.
LINC
Line increment.  The default for most programs is 1.0 which
will process each line of the image.  LINC=2.0 will process
every other line and the output image will have half as many
lines as the input.  LINC=.5 will process each line twice
and the output image will have twice as many lines as the
input.
NL
Number of lines.  The default for all programs is 0 which
will process all lines of the image.
NS
Number of samples.  The default for all programs is 0 which
will process all samples of the image.
SL
Starting line.  The default is 1 for all programs which will
start the processing with the first line or top of the
image.  Fifty lines fit on one page.  The number of samples
which fit on a page vary with bit type;  8 BIT = 25 samples,
16 BIT = 20, 32 BIT = 10. Think about the number of pages it
will take to print all of the area requested.  LINC and
SINC can be used so the whole area wanted can still be
listed, but only showing every fourth line and sample which
will reduce the amount of paper by 16, or if every pixel is
needed perhaps a smaller area would do.
SS
Starting sample.  The default is 1 for all programs which
will start the processing with the first sample or left
side of the image.
SINC
Sample increment.  The default for most programs is 1.0
which will process each sample of the image.  SINC=2.0 will
process every other sample and the output image will have
half as many samples as the input.  SINC=.5 will process
each sample twice and the output image will have twice as
many samples as the input.
