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