参数签名
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.
运行信息
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.

结果
shape_trans_xldshape_trans_xldShapeTransXldShapeTransXldShapeTransXldshape_trans_xld returns 2 (
H_MSG_TRUE)
if all parameters are correct.
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>).
If necessary, an exception is raised.
