Name
set_framegrabber_paramset_framegrabber_paramSetFramegrabberParamset_framegrabber_paramSetFramegrabberParamSetFramegrabberParam — Set specific parameters of an image acquistion device.
The operator set_framegrabber_paramset_framegrabber_paramSetFramegrabberParamset_framegrabber_paramSetFramegrabberParamSetFramegrabberParam sets specific parameters
for the image acquisition device specified by AcqHandleAcqHandleAcqHandleAcqHandleAcqHandleacqHandle.
Additional information for a specific image acquistion device is
available via info_framegrabberinfo_framegrabberInfoFramegrabberinfo_framegrabberInfoFramegrabberInfoFramegrabber. A comprehensive documentation
of all image acquistion device-specific parameters can be found in
the corresponding interface documentation in the directory
'doc/html/reference/acquisition'"doc/html/reference/acquisition""doc/html/reference/acquisition""doc/html/reference/acquisition""doc/html/reference/acquisition""doc/html/reference/acquisition".
Basically an image acquisition handle AcqHandleAcqHandleAcqHandleAcqHandleAcqHandleacqHandle cannot be used
in multiple threads. However, possible exceptions are described in the
specific reference documentation of the respective image acquisition interface.
Different image acquisition handles can be used safely with different threads
for each handle.
For a multithreaded application all image acquisition operators
(as listed in open_framegrabberopen_framegrabberOpenFramegrabberopen_framegrabberOpenFramegrabberOpenFramegrabber) are
an own group in which info_framegrabberinfo_framegrabberInfoFramegrabberinfo_framegrabberInfoFramegrabberInfoFramegrabber, open_framegrabberopen_framegrabberOpenFramegrabberopen_framegrabberOpenFramegrabberOpenFramegrabber,
close_framegrabberclose_framegrabberCloseFramegrabberclose_framegrabberCloseFramegrabberCloseFramegrabber and close_all_framegrabbersclose_all_framegrabbersCloseAllFramegrabbersclose_all_framegrabbersCloseAllFramegrabbersCloseAllFramegrabbers are
executed exclusively.
set_framegrabber_paramset_framegrabber_paramSetFramegrabberParamset_framegrabber_paramSetFramegrabberParamSetFramegrabberParam runs in parallel with all non-exclusive
operators inside and outside of this group.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Handle of the acquisition device to be used.

Parameter value to be set.
If the image acquisition device is open and the specified parameter /
parameter value is supported, the operator set_framegrabber_paramset_framegrabber_paramSetFramegrabberParamset_framegrabber_paramSetFramegrabberParamSetFramegrabberParam
returns the value 2 (H_MSG_TRUE). Otherwise an exception is raised.
