SystemFont
==========

**Inherits:** :ref:`Font<class_Font>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

A font loaded from a system font. Falls back to a default theme font if not implemented on the host OS.

.. rst-class:: classref-introduction-group

Description
-----------

**SystemFont** loads a font from a system font with the first matching name from :ref:`font_names<class_SystemFont_property_font_names>`.

It will attempt to match font style, but it's not guaranteed.

The returned font might be part of a font collection or be a variable font with OpenType "weight", "width" and/or "italic" features set.

You can create :ref:`FontVariation<class_FontVariation>` of the system font for fine control over its features.

\ **Note:** This class is implemented on iOS, Linux, macOS and Windows, on other platforms it will fallback to default theme font.

----

.. _class_SystemFont_property_oversampling:

.. rst-class:: classref-property

:ref:`float<class_float>` **oversampling** = ``0.0``

.. rst-class:: classref-property-setget

- void **set_oversampling** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_oversampling** **(** **)**

Font oversampling factor, if set to ``0.0`` global oversampling factor is used instead.

.. rst-class:: classref-item-separator

----

.. _class_SystemFont_property_subpixel_positioning:

.. rst-class:: classref-property

:ref:`SubpixelPositioning<enum_TextServer_SubpixelPositioning>` **subpixel_positioning** = ``1``

.. rst-class:: classref-property-setget

- void **set_subpixel_positioning** **(** :ref:`SubpixelPositioning<enum_TextServer_SubpixelPositioning>` value **)**
- :ref:`SubpixelPositioning<enum_TextServer_SubpixelPositioning>` **get_subpixel_positioning** **(** **)**

Font glyph subpixel positioning mode. Subpixel positioning provides shaper text and better kerning for smaller font sizes, at the cost of memory usage and font rasterization speed. Use :ref:`TextServer.SUBPIXEL_POSITIONING_AUTO<class_TextServer_constant_SUBPIXEL_POSITIONING_AUTO>` to automatically enable it based on the font size.
