描述
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.
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。
