SYNOPSIS

       gpiv_clip  [-h | --help] [-p | --print] [-t N | --threshold N] [-v | --version] [filename]

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.
