NAME
gpiv_mktestimg - Generates a simplified image for image processing. SYNOPSIS
gpiv_mktestimg [-h | --help] [-p | --print] [-t N | --threshold N] [-w N] [-v | --version] [filename] < stdin > stdout DESCRIPTION
gpiv_mktestimg generates an image (pair) in order to be processed by the processing tools. This program is provided for developing and testing image processing tools. 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 -v | --version Print version information on standard output, then exit successfully. -w N window size (default: 15) filename Input image filename. Overrides stdin and stdout with the full filename of the image. Output will be written to filename.png. Param- eters 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.
