NAME
gpiv_piv2hdf - Converts PIV-data HDF5 format.
SYNOPSIS
gpiv_piv2hdf [-e] [-h | --help] [-p | --print] [-v | --version] [-V | --verbose] filename
DESCRIPTION
gpiv_piv2hdf converts ASCII-formattd PIV-data (filename.piv), derived data, like vorticities (filename.vor), strain (filename.sstr, file-

analysis and post processing are included in filename.hdf.
This program does not use the parameter resources from libgpiv. The parameters may be defined by the command line options as explained
below.
Options
-e Exclude PIV data and data from post-processes.
-h | --help
On-line help.
-i Includes image data.
-p | --print
Prints parameters, command line options and input and output filenames to stdout. The output may be used as parameters of fasty for
future use by re-directing stdout to fasty.par.
-v | --version
Print version information on standard output, then exits successfully.
-V | --verbose
Program behaves more verbose by printing messages to stdout.
filename
Input PIV data filename, including .piv extension.
