Description

The operator set_framegrabber_lutset_framegrabber_lutSetFramegrabberLutSetFramegrabberLutset_framegrabber_lut sets 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.

set_framegrabber_lutset_framegrabber_lutSetFramegrabberLutSetFramegrabberLutset_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.

This operator modifies the state of the following input parameter:

• AcqHandleAcqHandleAcqHandleacqHandleacq_handle

During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.

Parameters

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

Handle of the acquisition device to be used.

ImageRedImageRedImageRedimageRedimage_red (input_control)  integer-array → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Red level of the LUT entries.

ImageGreenImageGreenImageGreenimageGreenimage_green (input_control)  integer-array → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Green level of the LUT entries.

ImageBlueImageBlueImageBlueimageBlueimage_blue (input_control)  integer-array → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Blue level of the LUT entries.

Result

The operator set_framegrabber_lutset_framegrabber_lutSetFramegrabberLutSetFramegrabberLutset_framegrabber_lut returns the value 2 ( H_MSG_TRUE) if the specified LUT is correct and the image acquisition device is open.
