def test_closed_xld(xld: HObject) -> Sequence[int]

def test_closed_xld_s(xld: HObject) -> int

Description

test_closed_xldtest_closed_xldTestClosedXldTestClosedXldtest_closed_xld tests each contour or polygon in XLDXLDXLDXLDxld, whether it is closed and returns the result in IsClosedIsClosedIsClosedisClosedis_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.

Execution Information

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