描述
test_closed_xldtest_closed_xldTestClosedXldTestClosedXldTestClosedXldtest_closed_xld tests each contour or polygon in
XLDXLDXLDXLDXLDxld, whether it is closed and returns the result in
IsClosedIsClosedIsClosedIsClosedisClosedis_closed. If the contour contour or polygon is closed, the
respective return value is 1, otherwise 0. A contour or polygon is
closed, if its last point is equal to its first point.
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。
