签名
def get_framegrabber_lut(acq_handle: HHandle) -> Tuple[Sequence[int], Sequence[int], Sequence[int]]
描述
算子 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.
注意
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.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
