Description

The operator select_shape_xldselect_shape_xldSelectShapeXldSelectShapeXldSelectShapeXldselect_shape_xld selects contours or polygons according to their shape. For each input contour or polygon in XLDXLDXLDXLDXLDxld the indicated features (FeaturesFeaturesFeaturesFeaturesfeaturesfeatures) are calculated. If each (OperationOperationOperationOperationoperationoperation = 'and'"and""and""and""and""and") or at least one (OperationOperationOperationOperationoperationoperation = 'or'"or""or""or""or""or") of the calculated features is within the limits (MinMinMinMinminmin,MaxMaxMaxMaxmaxmax) the contour respectively polygon is copied into the output. The parameters MinMinMinMinminmin and MaxMaxMaxMaxmaxmax can be set to 'min'"min""min""min""min""min" or 'max'"max""max""max""max""max" in order to leave bottom and top limits, respectively, open.

If only one feature (FeaturesFeaturesFeaturesFeaturesfeaturesfeatures) is used the value of OperationOperationOperationOperationoperationoperation is meaningless. Several features are processed in the sequence in which they are entered.The use of some features requires that the input contour respectively polygon must not intersect itself, otherwise the results 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).

Result

The operator select_shape_xldselect_shape_xldSelectShapeXldSelectShapeXldSelectShapeXldselect_shape_xld returns the value 2 (H_MSG_TRUE) if the input is not empty. The behavior in case of empty input (no input objects available) is set via 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>)set_system("no_object_result",<Result>). If necessary an exception is raised.
