Herror shape_trans_xld(const Hobject XLD, Hobject* XLDTrans, const char* Type)
Herror T_shape_trans_xld(const Hobject XLD, Hobject* XLDTrans, const Htuple Type)
def shape_trans_xld(xld: HObject, type: str) -> HObject
描述
shape_transshape_transShapeTransShapeTransShapeTransshape_trans transforms the input contours or polygons
depending on the parameter TypeTypeTypeTypetypetype:
- 'convex'
Convex hull.
- 'ellipse'
Ellipse with the same moments and area as the input contour or polygon. The
closed input contour or polygon must not intersect itself, otherwise the
resulting ellipse is 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).
- 'outer_circle'
Smallest enclosing circle.
- 'rectangle1'
Smallest enclosing rectangle parallel to the coordinate axes.
- 'rectangle2'
Smallest enclosing rectangle.
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。

结果
shape_trans_xldshape_trans_xldShapeTransXldShapeTransXldShapeTransXldshape_trans_xld 在所有参数正确时返回 2 ( H_MSG_TRUE )。
The behavior in case of empty input (no contours given) can be set
via 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>)。如有必要，则抛出异常。
