create_drawing_object_textT_create_drawing_object_textCreateDrawingObjectTextCreateDrawingObjectText — Create a text object which can be moved interactively.
Herror T_create_drawing_object_text(const Htuple Row, const Htuple Column, const Htuple String, Htuple* DrawID)
create_drawing_object_textcreate_drawing_object_textCreateDrawingObjectTextCreateDrawingObjectTextCreateDrawingObjectText 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_paramsGetDrawingObjectParamsGetDrawingObjectParamsGetDrawingObjectParams,
as well as its corresponding HALCON object with get_drawing_object_iconicget_drawing_object_iconicGetDrawingObjectIconicGetDrawingObjectIconicGetDrawingObjectIconic.
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_paramsSetDrawingObjectParamsSetDrawingObjectParamsSetDrawingObjectParams 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_windowAttachDrawingObjectToWindowAttachDrawingObjectToWindowAttachDrawingObjectToWindow 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_paramsSetDrawingObjectParamsSetDrawingObjectParamsSetDrawingObjectParams.
Once attached, the text can be moved by the user through interaction
with the window.
- 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.
Row coordinate of the text position.
Default value: 12
Column coordinate of the text position.
Default value: 12
Character string to be displayed.
Default value:
'Text'

Handle of the drawing object.
If the parameter values are correct, the operator
create_drawing_object_textcreate_drawing_object_textCreateDrawingObjectTextCreateDrawingObjectTextCreateDrawingObjectText returns the value 2 (H_MSG_2 (H_MSG_TRUE)).
Otherwise an exception is raised.
