描述
create_drawing_object_xldcreate_drawing_object_xldCreateDrawingObjectXldCreateDrawingObjectXldCreateDrawingObjectXldcreate_drawing_object_xld creates an XLD contour which can be modified
interactively in a HALCON window by the user. The contour is defined by the
coordinates RowRowRowRowrowrow and ColumnColumnColumnColumncolumncolumn of its points.
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 contour is editable by the user through interaction
with the window.
Further points can be added by left clicking on the window.
When clicking the contour segment between two consecutive points,
a new point is added between those points.
Each contour point can be moved by dragging its point handle.
A single contour point can be deleted by dragging it over one of the
neighboring contour points directly connected to it.
The contour can be closed by moving the last point onto the first
contour point. The contour can be moved as a whole by dragging it by the
handle in the center.
In addition, it is possible to assign a new contour to a drawing object with
set_drawing_object_xldset_drawing_object_xldSetDrawingObjectXldSetDrawingObjectXldSetDrawingObjectXldset_drawing_object_xld。
In contrast to the operator draw_xlddraw_xldDrawXldDrawXldDrawXlddraw_xld, this interaction does not block
the calling thread.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
此算子返回一个句柄。请注意，即使该句柄被用作特定算子的输入参数，这些算子仍可能改变此句柄类型的实例状态。
参数
RowRowRowRowrowrow (输入控制) coordinates.y-array → HTupleSequence[Union[float, int]]HTupleHtuple (real / integer) (double / int / long) (double / Hlong) (double / Hlong)
