描述
create_drawing_object_circle_sectorcreate_drawing_object_circle_sectorCreateDrawingObjectCircleSectorCreateDrawingObjectCircleSectorCreateDrawingObjectCircleSectorcreate_drawing_object_circle_sector 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 RowRowRowRowrowrow and
ColumnColumnColumnColumncolumncolumn of the center point, the RadiusRadiusRadiusRadiusradiusradius, and the start and end angle
StartAngleStartAngleStartAngleStartAnglestartAnglestart_angle and EndAngleEndAngleEndAngleEndAngleendAngleend_angle.
These parameters can be queried any time 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 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 RadiusRadiusRadiusRadiusradiusradius 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 该算子 draw_circledraw_circleDrawCircleDrawCircleDrawCircledraw_circle, this interaction does not block the
calling thread.
运行信息
- 多线程类型:可重入(与非独占操作符并行运行)。
- 多线程作用域:全局(可以从任何线程调用)。
- 未经并行化处理。
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.
