Description
gen_cross_contour_xldgen_cross_contour_xldGenCrossContourXldGenCrossContourXldGenCrossContourXldgen_cross_contour_xld generates an XLD contour in the shape of a
cross for each input point (RowRowRowRowrowrow,ColColColColcolcol).
Conceptually, the contour consists of two lines of length SizeSizeSizeSizesizesize,
which intersect exactly in the input point. Their orientation is determined
by AngleAngleAngleAngleangleangle. The cross is returned in CrossCrossCrossCrosscrosscross. If there are
multiple points to be processed, their coordinates must be passed as tuples.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
