Font
====
Font objects can be created from TrueType, OpenType,
Type1 or CFF fonts. In PDF there are also special
Type3 fonts.
Constructors
------------
.. class::
Font(name, data, index)
Font(name, filename, index)
Create a new font. Either from a buffer, a file name, or a
built-in font name.
The built-in standard PDF fonts are:
- ``"Times-Roman"``
- ``"Times-Italic"``
- ``"Times-Bold"``
- ``"Times-BoldItalic"``
- ``"Helvetica"``
- ``"Helvetica-Oblique"``
- ``"Helvetica-Bold"``
- ``"Helvetica-BoldOblique"``
- ``"Courier"``
- ``"Courier-Oblique"``
- ``"Courier-Bold"``
- ``"Courier-BoldOblique"``
- ``"Symbol"``
- ``"ZapfDingbats"``
The built-in CJK fonts are referenced by language code:
``"zh-Hant"``, ``"zh-Hans"``, ``"ja"``, ``"ko"``.
:param string name: Font name.
:param Buffer | ArrayBuffer | Uint8Array data: The font data if loaded from a buffer.
:param string filename: The name of the font file to load.
:param number index: Subfont index (only used for TTC fonts).
.. code-block::
var font1 = new mupdf.Font("Times-Roman")
var font2 = new mupdf.Font("ko")
var font3 = new mupdf.Font("Comic Sans", "/usr/share/fonts/truetype/msttcorefonts/Comic_Sans_MS.ttf")
var font4 = new mupdf.Font("Comic Sans", "/usr/share/fonts/truetype/msttcorefonts/Comic_Sans_MS.ttf", 1)
var font5 = new mupdf.Font("Freight Sans", fs.readFileSync("DroidSansFallbackFull.ttf"))

Instance methods
----------------
.. method:: Font.prototype.getName()
Get the font name.
:returns: string
.. code-block::
var name = font.getName()
.. method:: Font.prototype.encodeCharacter(unicode)
Get the glyph index for a unicode character. Glyph ``0`` is returned if the font does not have a glyph for the character.
:param number | string unicode: The unicode character, or the first unicode character of a string.
:returns: number.
.. code-block::
var index = font.encodeCharacter(0x42)
.. method:: Font.prototype.advanceGlyph(glyph , wmode)
Return advance width for a glyph in either horizontal or vertical writing mode.
:param number glyph: The glyph as unicode character.
:param number wmode: ``0`` for horizontal writing, and ``1`` for vertical writing, defaults to horizontal.
:returns: number
.. code-block::
var width = font.advanceGlyph(0x42)
.. method:: Font.prototype.isBold()
