## F2QLimit

the script call is:-

## vcm.F2QLimit(clip,int fspec = [] [, int grid = 10][,int inner = grid / 10][,int warn = 1])

clip: input clip must have constant dimensions and of RGB or YUV or Grey format only. All 3 planes of RGB, and YUV formats are processed.
fspec[]: Array of x and y frequency value pairs for limiting.
grid: checks for max value within + grid and -grid square.value range 1 to 50
inner: limits values in a square of -inner to inner around maximum detected. value range 0 to grid
warn: 0 no warning, 1 if search includes origin warns, 2 if search includes any axis warns.

This transforms data into frequency domain utilising libfftw3f-3.dll ( or, FFTW3 dll, or fftw.dll) of fftw.org being available in path. Searches for maximum value within (-grid to grid) around given coordinates and zeroes out the (-inner to inner) square
