描述
算子 diameter_xlddiameter_xldDiameterXldDiameterXldDiameterXlddiameter_xld calculates the
maximum distance between two points of each input contour or polygon.
The coordinates of these two extremes
and the distance between them will be returned. The input contour or polygon
must not intersect itself, otherwise the resulting parameters are not
meaningful (Whether the input contour or polygon intersects itself or not
can be determined with test_self_intersection_xldtest_self_intersection_xldTestSelfIntersectionXldTestSelfIntersectionXldTestSelfIntersectionXldtest_self_intersection_xld). If
the input contour or polygon is not closed it will be closed automatically.
如果传递多个轮廓或多边形，结果将按其在 XLDXLDXLDXLDXLDxld 中的顺序存储为元组。
注意
If the contour or polygon is empty, the results of Row1Row1Row1Row1row1row_1,
Column1Column1Column1Column1column1column_1, Row2Row2Row2Row2row2row_2 and Column2Column2Column2Column2column2column_2 (all of them = 0) may
lead to confusion.
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）。
- 在元组级别上自动并行化。

, if the input
is not empty. The reaction to empty input (no input contours are
available) may be determined with the help of the operator
