NAME

       gpiv_clip - Image clipping program for PIV images.

SYNOPSIS

       gpiv_clip  [-h  |  --help]  [-p  |  --print] [-t N | --threshold N] [-v | --version] [filename] < stdin >
       stdout

DESCRIPTION

       gpiv_clip sets all pixels below a pre-defined value to zero

       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

       -t N | --threshold N
              Threshold value to be set to zero

       -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.
