描述
The operator line_orientationline_orientationLineOrientationLineOrientationLineOrientationline_orientation returns the orientation
(-pi/2 < PhiPhiPhiPhiphiphi <= pi/2) of the given lines. If more
than one line is to be treated the line and column indices can be
passed as tuples. In this case PhiPhiPhiPhiphiphi is, of course, also
a tuple and contains the corresponding orientations.
运行信息
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
