gpiv_fft - Fast Fourier Transformation of image .
gpiv_fft [-h | --help] [-p | --print] [-v | --version] [filename] < stdin > stdout
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.
-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. SEE ALSO gpivtools
