Signature
void LineOrientation(const HTuple& RowBegin, const HTuple& ColBegin, const HTuple& RowEnd, const HTuple& ColEnd, HTuple* Phi)
static HTuple HMisc::LineOrientation(const HTuple& RowBegin, const HTuple& ColBegin, const HTuple& RowEnd, const HTuple& ColEnd)
static double HMisc::LineOrientation(double RowBegin, double ColBegin, double RowEnd, double ColEnd)
static void HOperatorSet.LineOrientation(HTuple rowBegin, HTuple colBegin, HTuple rowEnd, HTuple colEnd, out HTuple phi)

def line_orientation(row_begin: MaybeSequence[Union[int, float]], col_begin: MaybeSequence[Union[int, float]], row_end: MaybeSequence[Union[int, float]], col_end: MaybeSequence[Union[int, float]]) -> Sequence[float]
def line_orientation_s(row_begin: MaybeSequence[Union[int, float]], col_begin: MaybeSequence[Union[int, float]], row_end: MaybeSequence[Union[int, float]], col_end: MaybeSequence[Union[int, float]]) -> float
Description
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.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
