shape_trans_xldshape_trans_xldshape_trans_xldShapeTransXldShapeTransXld (Operator)

Name

shape_trans_xldshape_trans_xldshape_trans_xldShapeTransXldShapeTransXld — Transform the shape of contours or polygons.

Signature

Description

shape_transshape_transshape_transShapeTransShapeTrans transforms the input contours or polygons depending on the parameter TypeTypeTypeTypetype:

'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_xldtest_self_intersection_xldTestSelfIntersectionXldTestSelfIntersectionXld).

'outer_circle'

Smallest enclosing circle.

'rectangle1'

Smallest enclosing rectangle parallel to the coordinate axes.

'rectangle2'

Smallest enclosing rectangle.

Parallelization

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

Parameters

Result

shape_trans_xldshape_trans_xldshape_trans_xldShapeTransXldShapeTransXld 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>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). If necessary, an exception is raised.
