outlin - outline distinct DN sections in an image
PROGRAMMER: KBECKER

 OUTLIN will draw a border around distinct image sections that have
different DN values.  The user is allowed to specify the DN value to
use to outline each section.  This DN value should be chosen carefully.
The DN parameter must be a unique value not found in the input image.
This program performs the opposite function of the FILBND program which
replaces only values of the border DN.

ADDITIONAL NOTES:

Parm	Description
FROM	The input image that is to be outlined. This file may be 8 or 16 bit. The file is assumed to contain distinguishable areas of specific DN. Each of these areas will be outlined with the pixel value specified by the DN parameter.
TO	The image file created by OUTLIN. This is the result of the outlining process of the input file. All distinguishable areas of a specific DN value will be outlined with the value found in the DN parameter.
DN	This is the unique value of the outline boundary DN. It defaults to 1. It is up to the user to choose a value that does not previously exist in the file BEFORE processing.
SL	Starting line. The default is 1 for all programs which will start the processing with the first line or top of the image.
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.
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.
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.
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.
