impl<I: TeXInt, D: TeXDimen + Numeric<I>, CS: CSName<u8>> FontSystem for TfmFontSystem<I, D, CS>

Source§

type Char = u8

The type of Characters used by this font system.
Source§

type Int = I

The type of TeXInts used by this font system, for e.g. \skewchar, \hyphenchar etc. - these numbers may escape the actual character range of the font, so we use TeXInts instead of Characters.

The type of Fonts provided by this font system.
Source§

type Dim = D

The type of TeXDimens used by this font system, for e.g. \fontdimen, \fontcharwd etc.
Source§

type CS = CS

The type of control sequences used to give a name to a font; returned by e.g. \the when followed by a font.
Source§

fn new<ET: EngineTypes<Char = Self::Char, CSName = Self::CS>>( aux: &mut EngineAux<ET>, ) -> Self

Creates a new font system.
Source§

fn new_font<S: AsRef<str>, F: FileSystem>( &mut self, path: S, macroname: CS, fs: &mut F, ) -> Self::Font

Creates a new font with the given macroname and filepath (in plain TeX a .tfm-file).
Source§

fn null(&self) -> Self::Font

Returns the \nullfont.
