Description

create_drawing_object_circle_sectorcreate_drawing_object_circle_sectorCreateDrawingObjectCircleSectorCreateDrawingObjectCircleSectorCreateDrawingObjectCircleSector creates a circle sector region which can be modified interactively in a HALCON window by the user. The circle sector is defined by the coordinates RowRowRowRowrow and ColumnColumnColumnColumncolumn of the center point, the RadiusRadiusRadiusRadiusradius, and the start and end angle StartAngleStartAngleStartAngleStartAnglestartAngle and EndAngleEndAngleEndAngleEndAngleendAngle.

These parameters can be queried any time with get_drawing_object_paramsget_drawing_object_paramsGetDrawingObjectParamsGetDrawingObjectParamsGetDrawingObjectParams, as well as its corresponding HALCON object with get_drawing_object_iconicget_drawing_object_iconicGetDrawingObjectIconicGetDrawingObjectIconicGetDrawingObjectIconic.

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_paramsSetDrawingObjectParamsSetDrawingObjectParamsSetDrawingObjectParams 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_windowAttachDrawingObjectToWindowAttachDrawingObjectToWindowAttachDrawingObjectToWindow for further details. Once attached, the circle is editable by the user through interaction with the window. There are three possible transformations for a circle sector object: resizing, displacement and changing the arc angle. The RadiusRadiusRadiusRadiusradius of the circle can be modified by dragging the circular arc. By clicking on the center, the circle sector can be moved across the HALCON window. The angle arc can be modified by dragging the handles of the circle sector.

In contrast to the operator draw_circledraw_circleDrawCircleDrawCircleDrawCircle, 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.

Parameters

RowRowRowRowrow (input_control)  coordinates.y HTupleHTupleHtuple (real) (double) (double) (double)

Row coordinate of the center.

Default value: 100

ColumnColumnColumnColumncolumn (input_control)  coordinates.x HTupleHTupleHtuple (real) (double) (double) (double)

Column coordinate of the center.

Default value: 100

RadiusRadiusRadiusRadiusradius (input_control)  number HTupleHTupleHtuple (real) (double) (double) (double)

Radius of the circle.

Default value: 80

StartAngleStartAngleStartAngleStartAnglestartAngle (input_control)  angle.rad HTupleHTupleHtuple (real) (double) (double) (double)

Start angle of the arc.

Default value: 0

EndAngleEndAngleEndAngleEndAngleendAngle (input_control)  angle.rad HTupleHTupleHtuple (real) (double) (double) (double)

End angle of the arc.

Default value: 3.14159

Result

If the parameter values are correct the operator create_drawing_object_circle_sectorcreate_drawing_object_circle_sectorCreateDrawingObjectCircleSectorCreateDrawingObjectCircleSectorCreateDrawingObjectCircleSector returns the value 2 (H_MSG_TRUE). Otherwise an exception is raised.
