UFO Extractor
=============

Tools for extracting data from font binaries into UFO objects.

Supported input formats
-----------------------

The following font formats are supported:

- CFF or TrueType-flavored OpenType fonts (``*.otf``, ``*.ttf``)
- `FontTools `__ TTX files
(``*.ttx``)
- WOFF 1.0/2.0 (``*.woff``, ``*.woff2``)
- PostScript Type1 fonts (``*.pfa``, ``*.pfb``, etc.)
- FontLab files (``*.vfb``, when installed with optional dependency "vfb")

Note however, that what data will (or even could) be exported will depend on
input file format and the file itself.

Python module
-------------

The example below demonstrates how one can import data into
a `ufoLib2 `__
or `Defcon `__ ``Font`` instance:

.. code:: python

>>> import extractor
>>> from ufoLib2 import Font # alternatively: from defcon import Font
>>> ufo = Font()
>>> extractor.extractUFO("/path/to/MyFont.ttf", ufo)
>>> ufo.save("/path/to/MyFont.ufo")

Console script
--------------

A console script for one-off conversion is also provided
(note: see Installation below):

.. code::

$ extractufo -h
usage: extractufo [-h] [-m {ufoLib2,defcon}] [-z] FONT_FILE [FONT_FILE ...]

Extract data from font binaries and build UFO objects from them.

positional arguments:
FONT_FILE Input font path

options:
-h, --help show this help message and exit
-m {ufoLib2,defcon}, --ufo-module {ufoLib2,defcon}
Select the default library for writing UFOs (default: autodetect, prefer ufoLib2)
-z, --zip Output UFO ZIP

Each resulting UFO will be saved as FONT_FILE.ufo(z) in the same directory as the original FONT_FILE.
If destination file or directory already exists, conversion for that source file will be skipped and the application exit code will indicate an error.

Installation
------------

You can install ``extractor`` with ``pip``:

.. code::

$ pip install ufo-extractor

To install with support for extracting from vfb files:

.. code::

$ pip install ufo-extractor[vfb]

If you want to use the console script and have neither `ufoLib2` nor `defcon`
installed (or aren't sure), running the following will install `ufoLib2` as well
to ensure that the script works:

.. code::

$ pip install ufo-extractor[script]

The options may also be combined:

.. code::

$ pip install ufo-extractor[vfb][script]

Note that, for historical reasons, the package is listed on the
`Python Package Index `__ under the name
``ufo-extractor``, to disambiguate it from another package also called "extractor".
However, the import name for the package remains ``extractor``, without prefix.
