> Native bindings to [fonttools][1] to decompile and compile fonts.

How It Works

[fonttools][1] (also known as TTX) is a library for manipulating fonts,
written in Python. It supports TrueType, OpenType, AFM and to an extent Type 1,
and some Mac-specific formats. Using [Addons][2] it's possible to bridge Python
to Node, natively, using C++ and Python's [Python/C API][3]—which is
exactly what node-fontools does.

Current Status

So far, the only functions that have been bridged are the abilities to decompile
fonts to XML and compile XML to font binary.

$3

Python 2.7 is the only supported version at the moment.

How To Use

``js
import fonttools from 'fonttools';
import { readFileSync } from 'fs';

// Get the decompile and compile methods
const { decompile, compile } = fonttools();

// Read a font file as a buffer
const fontBuffer = readFileSync('font.ttf');

// Decompile the font to another buffer
const fontXMLBuffer = decompile(fontBuffer);

// Insert logic here to manipulate font

// Compile font from an XML file as a buffer
const fontBinaryBuffer = compile(fontXMLBuffer);

// Insert logic to save font file buffer here
`

$3

A function that takes a path to [fonttools/Lib][4] and returns an object with
two methods: decompile and compile. By default it uses the [included
submodule][5].

#### decompile

Takes a font file buffer and returns another buffer with the XML of the
decompiled font.

#### compile`

Takes an XML file buffer and returns another buffer with the compiled font file
binary.
