| USAGE |
add_rmg infile1 infile2 outfile width length sign conserve sign: 1 (add) or -1 (subtract) conserve: 1 makes out phase = zero if phase from either file is zero infiles must be of same width and length, in rmg format. rmg format contains alternating real and imaginary lines of real and imaginary pixels Lines contain width pixels. |
| FUNCTION |
Add or subtract rmg image files. |
| PROCESS |
From infile1 we have line in_amp1 and line in_phi1 with width pixels each. From infile2 we have line in_amp2 and line in_phi2 with width pixels each. print lines of out_ampand out_phi to outfile For each pixel: out_amp = in_amp1 out_phi = in_phi1 + sign*in_phi2 unless conserve = 1, then if in_phi1 = in_phi2 = 0, out_phi = 0; |
