FontVariation
=============

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

A variation of a font with additional settings.

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

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

Provides OpenType variations, simulated bold / slant, and additional font settings like OpenType features and extra spacing.

To use simulated bold font variant:


.. tabs::

 .. code-tab:: gdscript

    var fv = FontVariation.new()
    fv.base_font = load("res://BarlowCondensed-Regular.ttf")
    fv.variation_embolden = 1.2
    $Label.add_theme_font_override("font", fv)
    $Label.add_theme_font_size_override("font_size", 64)

 .. code-tab:: csharp

    var fv = new FontVariation();
    fv.SetBaseFont(ResourceLoader.Load<FontFile>("res://BarlowCondensed-Regular.ttf"));
    fv.SetVariationEmbolden(1.2);
    GetNode("Label").AddThemeFontOverride("font", fv);
    GetNode("Label").AddThemeFontSizeOverride("font_size", 64);



To set the coordinate of multiple variation axes:

::

    var fv = FontVariation.new();
    var ts = TextServerManager.get_primary_interface()
    fv.base_font = load("res://BarlowCondensed-Regular.ttf")
    fv.variation_opentype = { ts.name_to_tag("wght"): 900, ts.name_to_tag("custom_hght"): 900 }

Font OpenType variation coordinates. More info: `OpenType variation tags <https://docs.microsoft.com/en-us/typography/opentype/spec/dvaraxisreg>`__.

\ **Note:** This :ref:`Dictionary<class_Dictionary>` uses OpenType tags as keys. Variation axes can be identified both by tags (:ref:`int<class_int>`, e.g. ``0x77678674``) and names (:ref:`String<class_String>`, e.g. ``wght``). Some axes might be accessible by multiple names. For example, ``wght`` refers to the same axis as ``weight``. Tags on the other hand are unique. To convert between names and tags, use :ref:`TextServer.name_to_tag()<class_TextServer_method_name_to_tag>` and :ref:`TextServer.tag_to_name()<class_TextServer_method_tag_to_name>`.

\ **Note:** To get available variation axes of a font, use :ref:`Font.get_supported_variation_list()<class_Font_method_get_supported_variation_list>`.

- :ref:`Transform2D<class_Transform2D>` **get_variation_transform**\ (\ )

2D transform, applied to the font outlines, can be used for slanting, flipping and rotating glyphs.

For example, to simulate italic typeface by slanting, apply the following transform ``Transform2D(1.0, slant, 0.0, 1.0, 0.0, 0.0)``.
