NAME

       gpiv_fft - Fast Fourier Transformation of image .

SYNOPSIS

       gpiv_fft [-h | --help] [-p | --print] [-v | --version] [filename] < stdin > stdout

DESCRIPTION

       gpiv_fft converts an image to its Fourier Transform using FFT.

       The parameters read from the configuration resources (containing the key GPIV_IMGPROC) may
       be overruled by the command line options, as explained below.

Options

       -h | --help
              On-line help

       -v | --version
              Print version information on standard output, then exit successfully.

       filename
              Input image filename. Overrides stdin and stdout with  the  full  filename  of  the
              image.   Output   will  be  written  to  filename.png.  Parameters  are  stored  in
              filename.par and may be used for future use by including them in ./gpivrc. If stdin
              and stdout are used, the input is expected to be a PNG formatted image.
