MAD - Perform algebra on 8 bit images
PROGRAMMER:EELIASON
MAD performs simple algebra on one or two input files to create a
single output file.   The equations shown below are applied to the
input files. The parameters MUL1, MUL2, and ADD are input parameters.

OUT(i,j) = MUL1*IN1(i,j) + ADD (one input file)
                   or
OUT(i,j) = MUL1*IN1(i,j) + MUL2*IN2(i,j) + ADD (two input files)

This program works on 8-bit data only.

ADDITIONAL NOTES:

Parm	Description
MUL1	Multiplied to every pixel in first input image
MUL2	Multiplied to every pixel in second input image
ADD	Additive constant. This parameter applied after MUL1 and MUL2 have been applied.
NL	Number of lines. The default is 0 which will process all lines of the image.
NS	Number of samples. The default is 0 which will process all samples of the image.
SL	Starting line. The default is 1 which will start the processing with the first line or top of the image.
SS	Starting sample. The default is 1 which will start the processing with the first sample or left side of the image.
LINC	Line increment. The default 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 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.
