test_closed_xldtest_closed_xldTestClosedXldTestClosedXldtest_closed_xld (Operator)
Name
test_closed_xldtest_closed_xldTestClosedXldTestClosedXldtest_closed_xld — Test whether contours or polygons are closed.
Signature
Herror test_closed_xld(const Hobject XLD, Hlong* IsClosed)
Herror T_test_closed_xld(const Hobject XLD, Htuple* IsClosed)
def test_closed_xld(xld: HObject) -> Sequence[int]
def test_closed_xld_s(xld: HObject) -> int
Description
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.
