def select_shape_xld(xld: HObject, features: MaybeSequence[str], operation: str, min: MaybeSequence[Union[int, float, str]], max: MaybeSequence[Union[int, float, str]]) -> HObject
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
).
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

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.
