Description

create_drawing_object_ellipsecreate_drawing_object_ellipseCreateDrawingObjectEllipseCreateDrawingObjectEllipseCreateDrawingObjectEllipsecreate_drawing_object_ellipse creates an ellipse which can be modified interactively in a HALCON window by the user. The ellipse is defined by the coordinates of its center point, RowRowRowRowrowrow and ColumnColumnColumnColumncolumncolumn, the lengths of its respective half axis, Radius1Radius1Radius1Radius1radius1radius_1 and Radius2Radius2Radius2Radius2radius2radius_2, and its orientation PhiPhiPhiPhiphiphi.

The parameters can be queried with get_drawing_object_paramsget_drawing_object_paramsGetDrawingObjectParamsGetDrawingObjectParamsGetDrawingObjectParamsget_drawing_object_params, as well as its corresponding HALCON object with get_drawing_object_iconicget_drawing_object_iconicGetDrawingObjectIconicGetDrawingObjectIconicGetDrawingObjectIconicget_drawing_object_iconic.

In addition to those parameters, every drawing object has a number of parameters which determine the appearance of the object in the HALCON window. See set_drawing_object_paramsset_drawing_object_paramsSetDrawingObjectParamsSetDrawingObjectParamsSetDrawingObjectParamsset_drawing_object_params for details on the number and meaning of those parameters.

In order to enable the interactive modification with the drawing object, the object must be attached to an existing window. See attach_drawing_object_to_windowattach_drawing_object_to_windowAttachDrawingObjectToWindowAttachDrawingObjectToWindowAttachDrawingObjectToWindowattach_drawing_object_to_window for further details. Once attached, the ellipse is editable by the user through interaction with the window. There are three possible transformations for an ellipse object: resizing, displacement and rotation. The ellipse can be resized by clicking close to the vertex handles. The orientation and thus the rotation of the ellipse can be modified by dragging on a vertex of the first half axis. The ellipse can be moved in the HALCON window by dragging the center.

In contrast to the operator draw_ellipsedraw_ellipseDrawEllipseDrawEllipseDrawEllipsedraw_ellipse, this interaction does not block the calling thread.

Execution Information

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Result

If the parameter values are correct the operator create_drawing_object_ellipsecreate_drawing_object_ellipseCreateDrawingObjectEllipseCreateDrawingObjectEllipseCreateDrawingObjectEllipsecreate_drawing_object_ellipse returns the value TRUE. Otherwise an exception is raised.
