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.
An image acquisition handle AcqHandleAcqHandleAcqHandleAcqHandleAcqHandleacqHandle cannot be shared between
multiple threads. Different image acquisition handles can be used
independently and safely in different threads.
For a multithreaded application the image acquisition operators 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.
