Description

create_drawing_object_rectangle2create_drawing_object_rectangle2CreateDrawingObjectRectangle2CreateDrawingObjectRectangle2create_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 RowRowRowrowrow and ColumnColumnColumncolumncolumn of its center, its orientation PhiPhiPhiphiphi, and the lengths of its half axis, Length1Length1Length1length1length_1 and Length2Length2Length2length2length_2 respectively. The created rectangle is returned in the handle DrawIDDrawIDDrawIDdrawIDdraw_id.

These parameters can be queried any time with get_drawing_object_paramsget_drawing_object_paramsGetDrawingObjectParamsGetDrawingObjectParamsget_drawing_object_params, as well as its corresponding HALCON object with get_drawing_object_iconicget_drawing_object_iconicGetDrawingObjectIconicGetDrawingObjectIconicget_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_paramsSetDrawingObjectParamsSetDrawingObjectParamsset_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_windowAttachDrawingObjectToWindowAttachDrawingObjectToWindowattach_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_rectangle2DrawRectangle2DrawRectangle2draw_rectangle2, this interaction does not block the calling thread.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

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.

Parameters

Default: 150

Result

If the parameter values are correct the operator create_drawing_object_rectangle2create_drawing_object_rectangle2CreateDrawingObjectRectangle2CreateDrawingObjectRectangle2create_drawing_object_rectangle2 returns the value 2 ( H_MSG_TRUE) . Otherwise an exception is raised.
