PURPOSE

Adds the value in the first image times a factor to the value in the second image times a second factor i.e. P3 = P1 * factor1 + P2 * factor2. The sum is placed in an output file.   Example.

USAGE

.OPERATION: ADD F

.INPUT FILE: PIC001
[Enter name of the first file to be added. (Header positions from this file are transferred to output.)]

.NEXT INPUT FILE: PIC002
[Enter name of the next file to be added. Can be same as first input file.]

.FACTORS FOR FIRST & SECOND FILES: 7.1, 8.6
[Multiplicative factors.]

.OUTPUT FILE: PIC999
[Enter the name of the output file. Can be same as either input file]

NOTES

1. Only works for files with the same dimensions.

2. Does not work for Fourier files.
