Description

The operator line_orientationline_orientationLineOrientationLineOrientationline_orientation returns the orientation (-pi/2 < PhiPhiPhiphiphi <= 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 PhiPhiPhiphiphi is, of course, also a tuple and contains the corresponding orientations.

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.
