The operator diameter_xlddiameter_xldDiameterXldDiameterXldDiameterXld 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_xldTestSelfIntersectionXldTestSelfIntersectionXldTestSelfIntersectionXld). If the input contour or polygon is not closed it will be closed automatically. If more than one contour or polygon is passed, the results are stored in tuples in the same order as the respective contours or polygons in XLDXLDXLDXLDXLD.


If the contour or polygon is empty, the results of Row1Row1Row1Row1row1, Column1Column1Column1Column1column1, Row2Row2Row2Row2row2 and Column2Column2Column2Column2column2 (all of them = 0) may lead to confusion.

The operator diameter_xlddiameter_xldDiameterXldDiameterXldDiameterXld returns the value 2 (H_MSG_TRUE), 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 set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). If necessary an exception is raised.
