Description

create_drawing_object_textcreate_drawing_object_textCreateDrawingObjectTextCreateDrawingObjectTextcreate_drawing_object_text creates a text object which can be moved interactively across a HALCON window. The coordinates RowRowRowrowrow and ColumnColumnColumncolumncolumn define the position of the text.

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 text 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. The text will be displayed with the current font settings of the HALCON window by default. However, the font setting can be adjusted with set_drawing_object_paramsset_drawing_object_paramsSetDrawingObjectParamsSetDrawingObjectParamsset_drawing_object_params. Once attached, the text can be moved by the user through interaction with the window.
