def get_framegrabber_lut(acq_handle: HHandle) -> Tuple[Sequence[int], Sequence[int], Sequence[int]]

Description

The operator get_framegrabber_lutget_framegrabber_lutGetFramegrabberLutGetFramegrabberLutget_framegrabber_lut queries the look-up table (LUT) of the image acquisition device specified by AcqHandleAcqHandleAcqHandleacqHandleacq_handle. Note that this operation is not supported for all kinds of image acquisition devices.

Attention

For a multithreaded application, info_framegrabberinfo_framegrabberInfoFramegrabberInfoFramegrabberinfo_framegrabber, open_framegrabberopen_framegrabberOpenFramegrabberOpenFramegrabberopen_framegrabber, and close_framegrabberclose_framegrabberCloseFramegrabberCloseFramegrabberclose_framegrabber are executed exclusively.

get_framegrabber_lutget_framegrabber_lutGetFramegrabberLutGetFramegrabberLutget_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.

Parameters

AcqHandleAcqHandleAcqHandleacqHandleacq_handle (input_control)  framegrabber → HFramegrabber, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of the acquisition device to be used.

Result

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