GPIV_ROT180(1)						      General Commands Manual						    GPIV_ROT180(1)

NAME

       gpiv_rot180 - Simple data manipulation tool for PIV data.

SYNOPSIS

       gpiv_rot180 [-h | --help] [-p | --print] [-p | --version] [filename] < stdin > stdout

DESCRIPTION

       gpiv_rot180  rotates  the  data	over 180 degrees.  As rotating over 180 degrees is identic to flipping over x as well as over y-direction,
       flipx and flipy may be used instead of gpiv_rot180.

       The parameters read from the configuration resources (containing the key POST) may be overruled by the command line options,  as  explained
       below.

Options
       -h | --help
	      On-line help.

       -p | --print
	      Prints  parameters,  command  line  options  and	input  and  output  filenames  to  stdout. The output may be used as parameters of
	      gpiv_rot180 for future use by re-directing stdout to gpiv_rot180.par.

       -v | --version
	      Print version information on standard output, then exits successfully.

       filename
	      Input PIV file. Overrides stdin and stdout. Output will be written to filename.ma.piv. The parameters will be written or appended to
	      filename.par.
