Description🔗

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

Attention🔗

For a multithreaded application, info_framegrabberInfoFramegrabber, open_framegrabberOpenFramegrabber, and close_framegrabberCloseFramegrabber are executed exclusively.

get_framegrabber_lutGetFramegrabberLut runs in parallel with all non-exclusive operators inside and outside of this group.

Execution information🔗

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🔗

AcqHandleacqHandleacq_handle (input_control) framegrabber → (handle)HTuple (HHandle)HFramegrabber, HTuple (IntPtr)HHandleHtuple (handle)

Handle of the acquisition device to be used.

ImageRedimageRedimage_red (output_control) integer-array → (integer)HTuple (Hlong)HTuple (int / long)Sequence[int]Htuple (Hlong)

Red level of the LUT entries.

ImageGreenimageGreenimage_green (output_control) integer-array → (integer)HTuple (Hlong)HTuple (int / long)Sequence[int]Htuple (Hlong)

Green level of the LUT entries.

Blue level of the LUT entries.

Result🔗

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