Description

create_drawing_object_ellipse_sectorcreate_drawing_object_ellipse_sectorCreateDrawingObjectEllipseSectorCreateDrawingObjectEllipseSectorCreateDrawingObjectEllipseSector creates an ellipse sector which can be modified interactively in a HALCON window by the user. The ellipse sector is defined by the coordinates RowRowRowRowrow and ColumnColumnColumnColumncolumn of its center, the lengths of its respective half axis, Radius1Radius1Radius1Radius1radius1 and Radius2Radius2Radius2Radius2radius2, the start and end angles of the arc, StartAngleStartAngleStartAngleStartAnglestartAngle and EndAngleEndAngleEndAngleEndAngleendAngle, and its orientation PhiPhiPhiPhiphi.

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 ellipse sector is editable by the user through interaction with the window. There are four possible transformations for an ellipse sector object: resizing, displacement, rotation, and changing the arc angle. The ellipse sector can be moved in the HALCON window by dragging the center. The orientation and thus the rotation of the ellipse sector can also be modified by dragging on a vertex handle of the first half axis. The size and angles of the ellipse sector can be modified by dragging close to the vertex handles.

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

Note that since internal structures are allocated during create_drawing_object_ellipse_sectorcreate_drawing_object_ellipse_sectorCreateDrawingObjectEllipseSectorCreateDrawingObjectEllipseSectorCreateDrawingObjectEllipseSector and the following operators the draw object should be explicitly freed if it is no longer needed.

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_ellipse_sectorcreate_drawing_object_ellipse_sectorCreateDrawingObjectEllipseSectorCreateDrawingObjectEllipseSectorCreateDrawingObjectEllipseSector returns the value 2 (H_MSG_TRUE). Otherwise an exception is raised.
