-Function to get a curve from text and curve objects. It is typically used by exporters, render
-engines, and tools that need to access the curve representing the object.
-
-The function takes the evaluated dependency graph as a required parameter and optionally a boolean
-apply_modifiers which defaults to false. If apply_modifiers is true and the object is a curve object,
-the spline deform modifiers are applied on the control points. Note that constructive modifiers and
-modifiers that are not spline-enabled will not be applied. So modifiers like Array will not be applied
-and deform modifiers that have Apply On Spline disabled will not be applied.
-
-If the object is a text object. The text will be converted into a 3D curve and returned. Modifiers are
-never applied on text objects and apply_modifiers will be ignored. If the object is neither a curve nor
-a text object, an error will be reported.
-
-.. note:: The resulting curve is owned by the object. It can be freed by calling `object.to_curve_clear()`.
-.. note::
-   The resulting curve must be treated as temporary, and can not be referenced from objects in the main

+- Enable :ref:`Developer Extra <blender_manual:prefs-interface-dev-extras`
   and :ref:`Python Tooltips <blender_manual:prefs-interface-tooltips-python>`.
 - The :ref:`Python Console <blender_manual:bpy.types.SpaceConsole>`
   is great for testing one-liners; it has autocompletion so you can inspect the API quickly.
