Member Variables
----------------

  .. _class_BitmapFont_ascent:

- :ref:`float<class_float>` **ascent** - Ascent (number of pixels above the baseline).

  .. _class_BitmapFont_distance_field:

- :ref:`bool<class_bool>` **distance_field** - If ``true`` distance field hint is enabled.

  .. _class_BitmapFont_fallback:

- :ref:`BitmapFont<class_bitmapfont>` **fallback** - The fallback font.

  .. _class_BitmapFont_height:

- :ref:`float<class_float>` **height** - Total font height (ascent plus descent) in pixels.


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

Renders text using ``*.fnt`` fonts containing texture atlases. Supports distance fields. For using vector font files like TTF directly, see :ref:`DynamicFont<class_dynamicfont>`.

Member Function Description
---------------------------

.. _class_BitmapFont_add_char:

- void **add_char** **(** :ref:`int<class_int>` character, :ref:`int<class_int>` texture, :ref:`Rect2<class_rect2>` rect, :ref:`Vector2<class_vector2>` align=Vector2( 0, 0 ), :ref:`float<class_float>` advance=-1 **)**

Adds a character to the font, where ``character`` is the unicode value, ``texture`` is the texture index, ``rect`` is the region in the texture (in pixels!), ``align`` is the (optional) alignment for the character and ``advance`` is the (optional) advance.

.. _class_BitmapFont_add_kerning_pair:

- void **add_kerning_pair** **(** :ref:`int<class_int>` char_a, :ref:`int<class_int>` char_b, :ref:`int<class_int>` kerning **)**

Adds a kerning pair to the ``BitmapFont`` as a difference. Kerning pairs are special cases where a typeface advance is determined by the next character.

.. _class_BitmapFont_add_texture:

- void **add_texture** **(** :ref:`Texture<class_texture>` texture **)**

Adds a texture to the ``BitmapFont``.

.. _class_BitmapFont_clear:

- void **clear** **(** **)**

Clears all the font data and settings.

.. _class_BitmapFont_create_from_fnt:

- :ref:`int<class_int>` **create_from_fnt** **(** :ref:`String<class_string>` path **)**

Creates a BitmapFont from the ``*.fnt`` file at ``path``.

.. _class_BitmapFont_get_char_size:

- :ref:`Vector2<class_vector2>` **get_char_size** **(** :ref:`int<class_int>` char, :ref:`int<class_int>` next=0 **)** const

Returns the size of a character, optionally taking kerning into account if the next character is provided.

.. _class_BitmapFont_get_kerning_pair:

- :ref:`int<class_int>` **get_kerning_pair** **(** :ref:`int<class_int>` char_a, :ref:`int<class_int>` char_b **)** const

Returns a kerning pair as a difference.

.. _class_BitmapFont_get_texture:

- :ref:`Texture<class_texture>` **get_texture** **(** :ref:`int<class_int>` idx **)** const

Returns the font atlas texture at index ``idx``.

.. _class_BitmapFont_get_texture_count:

- :ref:`int<class_int>` **get_texture_count** **(** **)** const

Returns the number of textures in the BitmapFont atlas.
