描述
create_drawing_object_rectangle1create_drawing_object_rectangle1CreateDrawingObjectRectangle1CreateDrawingObjectRectangle1CreateDrawingObjectRectangle1create_drawing_object_rectangle1 creates a rectangle aligned along the
coordinate axis which can be modified interactively in a HALCON window by the
user. The rectangle is defined by the coordinates Row1Row1Row1Row1row1row_1, Column1Column1Column1Column1column1column_1,
Row2Row2Row2Row2row2row_2, and Column2Column2Column2Column2column2column_2 of its upper left and lower
right corner. The created rectangle is returned in the
handle DrawIDDrawIDDrawIDDrawIDdrawIDdraw_id。
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 rectangle is editable by the user through interaction
with the window.
There are two possible transformations for a rectangle1 object:
resizing and displacement.
The rectangle can be moved by dragging in the middle of the rectangle
and resized by dragging the handles of the corners.
In contrast to the operator draw_rectangle1draw_rectangle1DrawRectangle1DrawRectangle1DrawRectangle1draw_rectangle1, this interaction
does not block the calling thread.
