NAME
gpiv_process-chain - Processes a pipe of Gpiv-tool command’s.
SYNOPSIS
gpiv_process-chain [-af string] [-h | -help] [-n | -none] [-c | -clean]
[-fik] [-p | -print] [-pf -string] [-proc_*] [-t format] [-v |
-version] filename
DESCRIPTION
Gpiv_process-chain processes a pipe of gpiv commands. Image
evaluation/interrogation with gpiv_rr is always included, image
recording may be prepended before interrogation, validation and post-
processes may be appended to the chain. The filename represents the
name of the image to be evaluated. The file naming conventions are
idententic to the output of the individual Gpivtools programs: in case
the output are (validated/scaled) PIV data, the data will be directed
to filename.piv, with -proc_vorty the output will be called
filename.vor, with -proc_nstrain the output will be called
filename.nstr and, finally, with with -proc_sstrain the output will be
called filename.sstr.
This program does not use the parameter resources from libgpiv.
Options
-af string Append string to file-base name.
-h | --help
On-line help.
-n | --none
Suppresses real execution.
-c | -clean
Cleans up: removes raw image data and header.
-fik Use fi-keyline for filtering gpiv parms from README.
-p | --print
Prints parameters, command line options and input and output
filenames to stdout.
-pf string
Prepend string to file-base name.
-proc_*
Defines processes to be included in the chain. * is substituted
by: imgrec, valid, scale, manipiv, flipx, flipy, revert, rot90,
rot180 and vorty or nstrain or sstrain. Vorty, nstrain and
sstrain may not be used in combination with -t gpi.
-t format
Image type or format: hdf (.hdf), dav (.IMG) or a type as
defined by ImageMagic’s convert. Default is raw binary image
(.r).
-v | --version
Prints version information to standard output, then exits
successfully.
filename
Input image filename. Format may be: .r, .hdf (hdf), .IMG
(davis), .png, .gif, .tif or.bmp.
EXAMPLES
invoking: ’gpiv_process-chain -proc_valid -proc_scale testfile.png’
will actually perform: gpiv_rr < image.png | gpiv_errvec > testfile.piv
invoking: ’gpiv_process-chain -proc_imgrec -proc_valid -proc_scale
testfile.png’ will do: gpiv_recimg | gpiv_rr | gpiv_errvec | gpiv_scale
> testfile.piv
