set_framegrabber_lut — Set look-up table of the image acquisition device.
The operator set_framegrabber_lut sets the look-up table (LUT) of the image acquisition device specified by AcqHandle. Note that this operation is not supported for all kinds of image acquisition devices.
Basically an image acquisition handle AcqHandle cannot be used in multiple threads. However, possible exceptions are described in the specific reference documentation of the respective image acquisition interface. Different image acquisition handles can be used safely with different threads for each handle.
For a multithreaded application all image acquisition operators (as listed in open_framegrabber) are an own group in which info_framegrabber, open_framegrabber, close_framegrabber and close_all_framegrabbers are executed exclusively.
set_framegrabber_lut runs in parallel with all non-exclusive operators inside and outside of this group.
Handle of the acquisition device to be used.
Red level of the LUT entries.
Green level of the LUT entries.
Blue level of the LUT entries.
The operator set_framegrabber_lut returns the value 2 (H_MSG_TRUE) if the specified LUT is correct and the image acquisition device is open.
