To construct a font, use :py:func:`pyglet.font.load`, which will instantiate the platform-specific font class. Internally, this class is used by the platform classes to manage the set of textures into which glyphs are written. Attributes: texture_width: Default Texture width to use if ``optimize_glyph`` is False. texture_height: Default Texture height to use if ``optimize_glyph`` is False. optimize_fit: Determines max texture size by the ``glyph_fit`` attribute. If False, ``texture_width`` and ``texture_height`` are used. glyph_fit: Standard keyboard characters amount to around ~100 alphanumeric characters. This value is used to pre-calculate how many glyphs can be saved into a single texture atlas. Increase this if you plan to support more than this standard scenario. Performance is increased the less textures are used. However, it does consume more video memory. texture_internalformat: Determines how textures are stored in internal format. By default, ``GL_RGBA``. texture_min_filter: The default minification filter for glyph textures. By default, ``GL_LINEAR``. Can be changed to ``GL_NEAREST`` to prevent aliasing with pixelated fonts. texture_mag_filter: The default magnification filter for glyph textures. By default, ``GL_LINEAR``. Can be changed to ``GL_NEAREST`` to prevent aliasing with pixelated fonts. z(dict[str | int | tuple[Any, int], Glyph]glyphsirEr|r}T optimize_fitd glyph_fittexture_internalformattexture_min_filtertexture_mag_filterrascentrzClassVar[type[GlyphRenderer]]glyph_renderer_classzClassVar[type[GlyphTextureBin]]rfz list[Font] fallbackszGlyphRenderer | None_glyph_rendererz Glyph | None_missing_glyph _zero_glyphfloat pixel_sizer(rTchd|_d|_d|_d|_d|_i|_g|_dS)z/Initialize a font that can be used with Pyglet.N) texture_bin hb_resourcerrrrrrXs rrez Font.__init__+s@ ##  rc|jsY|||_|jd|_|j|_dSdS)zInitialize the glyph renderer and cache it on the Font.

If the entire text is larger than 'width', as much as possible will be used while breaking after a space or zero-width space character. If a newline is encountered in text, only text up to that newline will be used. If no break opportunities (newlines or spaces) occur within `width`, the text up to the first break opportunity will be used (this will exceed `width`). If there are no break opportunities, the entire text will be used. You can assume that each character of the text is represented by exactly one glyph; so the amount of text "used up" can be determined by examining the length of the returned glyph list.
