USAGE: powspec inimg outimg [-l] [-p] [-w] [-c] [-L]

powspec performs 2-D FFT to produce
image of power spectrum.
ARGUMENTS:
    inimg: input image filename (TIF)
   outimg: output image filename (TIF)

OPTIONS:
    -l: if set, displays linear scale for power in
        power spectrum, instead of logarithmic default.
    -p: if set, and image row or column is
        not a power of 2, image size is increased by zero-.
        padding; otherwise image size is decreased (default).
    -w: if set, no smoothing window is applied
        to initial image; default is to apply window.
    -c: display cross section of power spectrum
        of horizontal line through (0,0).
    -L: print Software License for this module
 

Example:
