create_drawing_object_circlecreate_drawing_object_circleCreateDrawingObjectCirclecreate_drawing_object_circleCreateDrawingObjectCircleCreateDrawingObjectCircle — Create a circle which can be modified interactively.
create_drawing_object_circlecreate_drawing_object_circleCreateDrawingObjectCirclecreate_drawing_object_circleCreateDrawingObjectCircleCreateDrawingObjectCircle creates a circular region which can be
interactively modified in a HALCON window by the user. The circle is defined
by the coordinates RowRowRowRowRowrow and ColumnColumnColumnColumnColumncolumn of its center, and
by its RadiusRadiusRadiusRadiusRadiusradius. The created circle is returned in the handle
DrawIDDrawIDDrawIDDrawIDDrawIDdrawID.
These parameters can be queried any time with get_drawing_object_paramsget_drawing_object_paramsGetDrawingObjectParamsget_drawing_object_paramsGetDrawingObjectParamsGetDrawingObjectParams,
as well as its corresponding HALCON object with get_drawing_object_iconicget_drawing_object_iconicGetDrawingObjectIconicget_drawing_object_iconicGetDrawingObjectIconicGetDrawingObjectIconic.
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_paramsSetDrawingObjectParamsset_drawing_object_paramsSetDrawingObjectParamsSetDrawingObjectParams 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_windowAttachDrawingObjectToWindowattach_drawing_object_to_windowAttachDrawingObjectToWindowAttachDrawingObjectToWindow
for further details. Once attached, the circle is editable by the user
through interaction within the window.
There are two possible transformations for a circle object: resizing and displacement.
By clicking close to the circular arc you can modify the RadiusRadiusRadiusRadiusRadiusradius of
the circle. By clicking on the center, the circle can be dragged
across the HALCON window.
In contrast to the operator draw_circledraw_circleDrawCircledraw_circleDrawCircleDrawCircle, this interaction does not
block the calling thread.
Note that since internal structures are allocated during create_drawing_object_circlecreate_drawing_object_circleCreateDrawingObjectCirclecreate_drawing_object_circleCreateDrawingObjectCircleCreateDrawingObjectCircle
and the following operators the drawing object should be explicitly
freed if it is no longer needed.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
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.
Row coordinate of the center.
Default value: 100
Column coordinate of the center.
Default value: 100
Radius of the circle.
Default value: 80
Handle of the drawing object.
If the parameter values are correct the operator create_drawing_object_circlecreate_drawing_object_circleCreateDrawingObjectCirclecreate_drawing_object_circleCreateDrawingObjectCircleCreateDrawingObjectCircle
returns the value 2 (H_MSG_TRUE). Otherwise an exception is raised.
