get_framegrabber_lutT_get_framegrabber_lutGetFramegrabberLutGetFramegrabberLut (Operator)
Name
get_framegrabber_lutT_get_framegrabber_lutGetFramegrabberLutGetFramegrabberLut — Query look-up table of the image acquisition device.
Signature
Description
The operator get_framegrabber_lutget_framegrabber_lutGetFramegrabberLutGetFramegrabberLutGetFramegrabberLut queries the look-up table (LUT) of
the image acquisition device specified by AcqHandleAcqHandleAcqHandleAcqHandleacqHandle. Note that
this operation is not supported for all kinds of image acquisition devices.
Attention
For a multithreaded application the image acquisition operators
(as listed in open_framegrabberopen_framegrabberOpenFramegrabberOpenFramegrabberOpenFramegrabber) are
an own group in which info_framegrabberinfo_framegrabberInfoFramegrabberInfoFramegrabberInfoFramegrabber, open_framegrabberopen_framegrabberOpenFramegrabberOpenFramegrabberOpenFramegrabber,
close_framegrabberclose_framegrabberCloseFramegrabberCloseFramegrabberCloseFramegrabber and close_all_framegrabbersclose_all_framegrabbersCloseAllFramegrabbersCloseAllFramegrabbersCloseAllFramegrabbers are
executed exclusively.
get_framegrabber_lutget_framegrabber_lutGetFramegrabberLutGetFramegrabberLutGetFramegrabberLut runs in parallel with all non-exclusive
operators inside and outside of this group.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters

Result
The operator get_framegrabber_lutget_framegrabber_lutGetFramegrabberLutGetFramegrabberLutGetFramegrabberLut returns the value 2 (H_MSG_TRUE)
if the image acquisition device is open.
