Name
get_framegrabber_lutT_get_framegrabber_lutGetFramegrabberLutGetFramegrabberLutget_framegrabber_lut — Query look-up table of the image acquisition device.
Signature
def get_framegrabber_lut(acq_handle: HHandle) -> Tuple[Sequence[int], Sequence[int], Sequence[int]]
Description
The operator get_framegrabber_lutget_framegrabber_lutGetFramegrabberLutGetFramegrabberLutGetFramegrabberLutget_framegrabber_lut queries the look-up table (LUT) of
the image acquisition device specified by AcqHandleAcqHandleAcqHandleAcqHandleacqHandleacq_handle. Note that
this operation is not supported for all kinds of image acquisition devices.
Attention
For a multithreaded application,
info_framegrabberinfo_framegrabberInfoFramegrabberInfoFramegrabberInfoFramegrabberinfo_framegrabber, open_framegrabberopen_framegrabberOpenFramegrabberOpenFramegrabberOpenFramegrabberopen_framegrabber, and
close_framegrabberclose_framegrabberCloseFramegrabberCloseFramegrabberCloseFramegrabberclose_framegrabber are executed exclusively.
get_framegrabber_lutget_framegrabber_lutGetFramegrabberLutGetFramegrabberLutGetFramegrabberLutget_framegrabber_lut 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.
