USAGE: lpfltr inimg outimg [-f CUTOFF <0.50>] [-s FLTRSIZE <odd>]
                           [-q QUICK_FLAG] [-L]

lpfltr performs low-pass filtering upon image
using filter window of chosen size; the default is to use
a Gaussian-shaped filter window.

ARGUMENTS:
    inimg: input image filename (TIF)
   outimg: output image filename (TIF)

OPTIONS:
     -f CUTOFF: <0.0 to 0.5> is the fraction of the passband;
                the default is 0.25, that is half of original passband.
  -s FLTR_SIZE: is the size of the filter; this will override
                the size that would otherwise be automatically set from
                the cutoff frequency; this size must be odd.
 -q QUICK_FLAG: for quick (and dirty) rectangular filtering;
                NOTE: specifying both cutoff frequency and filter
                size are redundant for the rectangular filter;
                the cutoff is used if both are specified.
