Tools for extracting data from font binaries into UFO objects.

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:

>>> 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):

$ 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:

$ pip install ufo-extractor

To install with support for extracting from vfb files:

$ 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:

$ pip install ufo-extractor[script]

The options may also be combined:

$ 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.
