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
