名称
create_drawing_object_lineT_create_drawing_object_lineCreateDrawingObjectLineCreateDrawingObjectLinecreate_drawing_object_line — Create a line which can be modified interactively.
参数签名
描述
create_drawing_object_linecreate_drawing_object_lineCreateDrawingObjectLineCreateDrawingObjectLineCreateDrawingObjectLinecreate_drawing_object_line creates a line which can be modified interactively
in a HALCON window by the user. The line is defined by the coordinates
of the first line point, Row1Row1Row1Row1row1row_1 and Column1Column1Column1Column1column1column_1, and the
second line point, Row2Row2Row2Row2row2row_2 and Column2Column2Column2Column2column2column_2.
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 line is editable by the user through interaction
with the window.
There are two possible transformations for a line object: resizing and
displacement.
A line point can be moved by dragging on the point handle. The whole
line can be moved by dragging the center of the line.
In contrast to 该算子 draw_linedraw_lineDrawLineDrawLineDrawLinedraw_line, 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.
