描述
create_drawing_object_rectangle2create_drawing_object_rectangle2CreateDrawingObjectRectangle2CreateDrawingObjectRectangle2CreateDrawingObjectRectangle2create_drawing_object_rectangle2 creates an oriented rectangle which can be
modified interactively in a HALCON window by the user. The rectangle is defined
by the coordinates RowRowRowRowrowrow and ColumnColumnColumnColumncolumncolumn of its center,
its orientation PhiPhiPhiPhiphiphi, and the lengths of its half axis,
Length1Length1Length1Length1length1length_1 and Length2Length2Length2Length2length2length_2 respectively. 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 three possible transformations for a rectangle2 object:
resizing, displacement and rotation.
The rectangle can be moved by dragging its center.
By dragging the side handles, the size of the rectangle can be modified.
The rectangle's orientation can only be changed by gripping a side
perpendicular to the first half axis.
In contrast to the operator draw_rectangle2draw_rectangle2DrawRectangle2DrawRectangle2DrawRectangle2draw_rectangle2, this interaction does not
block the calling thread.
执行信息
