What is this?
~~~~~~~~~~~~~
| fontTools is a library for manipulating fonts, written in Python. The
project includes the TTX tool, that can convert TrueType and OpenType
fonts to and from an XML text format, which is also called TTX. It
supports TrueType, OpenType, AFM and to an extent Type 1 and some
Mac-specific formats. The project has an `MIT open-source
licence <LICENSE>`__.
| Among other things this means you can use it free of charge.
Installation
~~~~~~~~~~~~
FontTools requires `Python <http://www.python.org/download/>`__ 2.7, 3.4
or later.
**NOTE** After January 1 2019, until no later than June 30 2019, the support
for *Python 2.7* will be limited to only bug fixes, and no new features will
be added to the ``py27`` branch. The upcoming FontTools 4.x series will require
*Python 3.5* or above. You can read more `here <https://python3statement.org>`__
and `here <https://github.com/fonttools/fonttools/issues/765>`__ for the
reasons behind this decision.
The package is listed in the Python Package Index (PyPI), so you can
install it with `pip <https://pip.pypa.io>`__:
.. code:: sh
pip install fonttools
If you would like to contribute to its development, you can clone the
repository from GitHub, install the package in 'editable' mode and
modify the source code in place. We recommend creating a virtual
environment, using `virtualenv <https://virtualenv.pypa.io>`__ or
Python 3 `venv <https://docs.python.org/3/library/venv.html>`__ module.
.. code:: sh
# download the source code to 'fonttools' folder
git clone https://github.com/fonttools/fonttools.git
cd fonttools
# create new virtual environment called e.g. 'fonttools-venv', or anything you like
python -m virtualenv fonttools-venv
# source the `activate` shell script to enter the environment (Un*x); to exit, just type `deactivate`
. fonttools-venv/bin/activate
# to activate the virtual environment in Windows `cmd.exe`, do
fonttools-venv\Scripts\activate.bat
# install in 'editable' mode
pip install -e .
TTX – From OpenType and TrueType to XML and Back
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Once installed you can use the ``ttx`` command to convert binary font
files (``.otf``, ``.ttf``, etc) to the TTX XML format, edit them, and
convert them back to binary format. TTX files have a .ttx file
extension.
.. code:: sh
ttx /path/to/font.otf
ttx /path/to/font.ttx
The TTX application can be used in two ways, depending on what
platform you run it on:
- As a command line tool (Windows/DOS, Unix, macOS)
- By dropping files onto the application (Windows, macOS)
TTX detects what kind of files it is fed: it will output a ``.ttx`` file
when it sees a ``.ttf`` or ``.otf``, and it will compile a ``.ttf`` or
``.otf`` when the input file is a ``.ttx`` file. By default, the output
file is created in the same folder as the input file, and will have the
same name as the input file but with a different extension. TTX will
*never* overwrite existing files, but if necessary will append a unique
number to the output filename (before the extension) such as
``Arial#1.ttf``
When using TTX from the command line there are a bunch of extra options.
These are explained in the help text, as displayed when typing
``ttx -h`` at the command prompt. These additional options include:
- specifying the folder where the output files are created
- specifying which tables to dump or which tables to exclude
- merging partial ``.ttx`` files with existing ``.ttf`` or ``.otf``
files
- listing brief table info instead of dumping to ``.ttx``
- splitting tables to separate ``.ttx`` files
- disabling TrueType instruction disassembly
The TTX file format
-------------------
The following tables are currently supported:
.. begin table list
.. code::
BASE, CBDT, CBLC, CFF, CFF2, COLR, CPAL, DSIG, EBDT, EBLC, FFTM,
Feat, GDEF, GMAP, GPKG, GPOS, GSUB, Glat, Gloc, HVAR, JSTF, LTSH,
MATH, META, MVAR, OS/2, SING, STAT, SVG, Silf, Sill, TSI0, TSI1,
TSI2, TSI3, TSI5, TSIB, TSID, TSIJ, TSIP, TSIS, TSIV, TTFA, VDMX,
VORG, VVAR, ankr, avar, bsln, cidg, cmap, cvar, cvt, feat, fpgm,
fvar, gasp, gcid, glyf, gvar, hdmx, head, hhea, hmtx, kern, lcar,
loca, ltag, maxp, meta, mort, morx, name, opbd, post, prep, prop,
sbix, trak, vhea and vmtx
.. end table list
Other tables are dumped as hexadecimal data.
TrueType fonts use glyph indices (GlyphIDs) to refer to glyphs in most
places. While this is fine in binary form, it is really hard to work
with for humans. Therefore we use names instead.
The glyph names are either extracted from the ``CFF`` table or the
``post`` table, or are derived from a Unicode ``cmap`` table. In the
latter case the Adobe Glyph List is used to calculate names based on
Unicode values. If all of these methods fail, names are invented based
on GlyphID (eg ``glyph00142``)
It is possible that different glyphs use the same name. If this happens,
we force the names to be unique by appending ``#n`` to the name (``n``
being an integer number.) The original names are being kept, so this has
no influence on a "round tripped" font.
Because the order in which glyphs are stored inside the binary font is
important, we maintain an ordered list of glyph names in the font.
Other Tools
~~~~~~~~~~~
Commands for merging and subsetting fonts are also available:
.. code:: sh
pyftmerge
pyftsubset
fontTools Python Module
~~~~~~~~~~~~~~~~~~~~~~~
The fontTools Python module provides a convenient way to
programmatically edit font files.
.. code:: py
>>> from fontTools.ttLib import TTFont
>>> font = TTFont('/path/to/font.ttf')
>>> font
<fontTools.ttLib.TTFont object at 0x10c34ed50>
>>>
A selection of sample Python programs is in the
`Snippets <https://github.com/fonttools/fonttools/blob/master/Snippets/>`__
directory.
Optional Requirements
---------------------
The ``fontTools`` package currently has no (required) external dependencies
besides the modules included in the Python Standard Library.
However, a few extra dependencies are required by some of its modules, which
are needed to unlock optional features.
The ``fonttools`` PyPI distribution also supports so-called "extras", i.e. a
set of keywords that describe a group of additional dependencies, which can be
used when installing via pip, or when specifying a requirement.
For example:
.. code:: sh
pip install fonttools[ufo,lxml,woff,unicode]
This command will install fonttools, as well as the optional dependencies that
are required to unlock the extra features named "ufo", etc.
- ``Lib/fontTools/misc/etree.py``
The module exports a ElementTree-like API for reading/writing XML files, and
allows to use as the backend either the built-in ``xml.etree`` module or
`lxml <https://http://lxml.de>`__. The latter is preferred whenever present,
as it is generally faster and more secure.
*Extra:* ``lxml``
- ``Lib/fontTools/ufoLib``
Package for reading and writing UFO source files; it requires:
* `fs <https://pypi.org/pypi/fs>`__: (aka ``pyfilesystem2``) filesystem
abstraction layer.
* `enum34 <https://pypi.org/pypi/enum34>`__: backport for the built-in ``enum``
module (only required on Python < 3.4).
*Extra:* ``ufo``
- ``Lib/fontTools/ttLib/woff2.py``
Module to compress/decompress WOFF 2.0 web fonts; it requires:
* `brotli <https://pypi.python.org/pypi/Brotli>`__: Python bindings of
the Brotli compression library.
*Extra:* ``woff``
- ``Lib/fontTools/ttLib/sfnt.py``
To better compress WOFF 1.0 web fonts, the following module can be used
instead of the built-in ``zlib`` library:
* `zopfli <https://pypi.python.org/pypi/zopfli>`__: Python bindings of
the Zopfli compression library.
*Extra:* ``woff``
- ``Lib/fontTools/unicode.py``
To display the Unicode character names when dumping the ``cmap`` table
with ``ttx`` we use the ``unicodedata`` module in the Standard Library.
The version included in there varies between different Python versions.
To use the latest available data, you can install:
* `unicodedata2 <https://pypi.python.org/pypi/unicodedata2>`__:
``unicodedata`` backport for Python 2.7 and 3.5 updated to the latest
Unicode version 9.0. Note this is not necessary if you use Python 3.6
as the latter already comes with an up-to-date ``unicodedata``.
*Extra:* ``unicode``
- ``Lib/fontTools/varLib/interpolatable.py``
Module for finding wrong contour/component order between different masters.
It requires one of the following packages in order to solve the so-called
"minimum weight perfect matching problem in bipartite graphs", or
the Assignment problem:
* `scipy <https://pypi.python.org/pypi/scipy>`__: the Scientific Library
for Python, which internally uses `NumPy <https://pypi.python.org/pypi/numpy>`__
arrays and hence is very fast;
* `munkres <https://pypi.python.org/pypi/munkres>`__: a pure-Python
module that implements the Hungarian or Kuhn-Munkres algorithm.
*Extra:* ``interpolatable``
- ``Lib/fontTools/varLib/plot.py``
Module for visualizing DesignSpaceDocument and resulting VariationModel.
* `matplotlib <https://pypi.org/pypi/matplotlib>`__: 2D plotting library.
*Extra:* ``plot``
- ``Lib/fontTools/misc/symfont.py``
Advanced module for symbolic font statistics analysis; it requires:
* `sympy <https://pypi.python.org/pypi/sympy>`__: the Python library for
symbolic mathematics.
*Extra:* ``symfont``
- ``Lib/fontTools/t1Lib.py``
To get the file creator and type of Macintosh PostScript Type 1 fonts
on Python 3 you need to install the following module, as the old ``MacOS``
module is no longer included in Mac Python:
* `xattr <https://pypi.python.org/pypi/xattr>`__: Python wrapper for
extended filesystem attributes (macOS platform only).
*Extra:* ``type1``
- ``Lib/fontTools/pens/cocoaPen.py``
Pen for drawing glyphs with Cocoa ``NSBezierPath``, requires:
* `PyObjC <https://pypi.python.org/pypi/pyobjc>`__: the bridge between
Python and the Objective-C runtime (macOS platform only).
- ``Lib/fontTools/pens/qtPen.py``
Pen for drawing glyphs with Qt's ``QPainterPath``, requires:
* `PyQt5 <https://pypi.python.org/pypi/PyQt5>`__: Python bindings for
the Qt cross platform UI and application toolkit.
- ``Lib/fontTools/pens/reportLabPen.py``
Pen to drawing glyphs as PNG images, requires:
* `reportlab <https://pypi.python.org/pypi/reportlab>`__: Python toolkit
for generating PDFs and graphics.
Testing
~~~~~~~
To run the test suite, you need to install `pytest <http://docs.pytest.org/en/latest/>`__.
When you run the ``pytest`` command, the tests will run against the
installed ``fontTools`` package, or the first one found in the
``PYTHONPATH``.
You can also use `tox <https://tox.readthedocs.io/en/latest/>`__ to
automatically run tests on different Python versions in isolated virtual
environments.
.. code:: sh
pip install tox
tox
Note that when you run ``tox`` without arguments, the tests are executed
for all the environments listed in tox.ini's ``envlist``. In our case,
this includes Python 2.7 and 3.7, so for this to work the ``python2.7``
and ``python3.7`` executables must be available in your ``PATH``.
You can specify an alternative environment list via the ``-e`` option,
or the ``TOXENV`` environment variable:
.. code:: sh
tox -e py27
TOXENV="py36-cov,htmlcov" tox

line-endings. Fix that.
3.37.2 (released 2019-02-05)
----------------------------
- [varLib] Temporarily revert the fix to ``load_masters()``, which caused a
crash in ``interpolate_layout()`` when ``deepcopy``-ing OTFs.
3.37.1 (released 2019-02-05)
----------------------------
- [varLib] ``load_masters()`` now actually assigns the fonts it loads to the
source.font attributes.
- [varLib] Fixed an MVAR table generation crash when sparse masters were
involved.
- [voltLib] ``parse_coverage_()`` returns a tuple instead of an ast.Enum.
- [feaLib] A MarkClassDefinition inside a block is no longer doubly indented
compared to the rest of the block.

----------------------------
- [svgLib] Added support for converting elliptical arcs to cubic bezier curves
(#1464).
- [py23] Added backport for ``math.isfinite``.

3.36.0 (released 2019-01-17)
----------------------------
- [ttx] Added ``--no-recalc-timestamp`` option to keep the original font's
``head.modified`` timestamp (#1455, #46).
- [ttx/psCharStrings] Fixed issues while dumping and round-tripping CFF2 table
with ttx (#1451, #1452, #1456).
- [voltLib] Fixed check for duplicate anchors (#1450). Don't try to read past
the ``END`` operator in .vtp file (#1453).
- [varLib] Use sentinel value -0x8000 (-32768) to ignore post.underlineThickness
and post.underlinePosition when generating MVAR deltas (#1449,
googlei18n/ufo2ft#308).
- [subset] Added ``--retain-gids`` option to subset font without modifying the
current glyph indices (#1443, #1447).
- [ufoLib] Replace deprecated calls to ``getbytes`` and ``setbytes`` with new
equivalent ``readbytes`` and ``writebytes`` calls. ``fs`` >= 2.2 no required.
- [varLib] Allow loading masters from TTX files as well (#1441).
3.35.2 (released 2019-01-14)
----------------------------
- [hmtx/vmtx]: Allow to compile/decompile ``hmtx`` and ``vmtx`` tables even
without the corresponding (required) metrics header tables, ``hhea`` and
``vhea`` (#1439).
- [varLib] Added support for localized axes' ``labelname`` and named instances'

3.35.1 (released 2019-01-09)
----------------------------
- [_m_a_x_p] Include ``maxComponentElements`` in ``maxp`` table's recalculation.
3.35.0 (released 2019-01-07)
----------------------------
- [psCharStrings] In ``encodeFloat`` function, use float's "general format" with
8 digits of precision (i.e. ``%8g``) instead of ``str()``. This works around
a macOS rendering issue when real numbers in CFF table are too long, and
also makes sure that floats are encoded with the same precision in python 2.7
and 3.x (#1430, googlei18n/ufo2ft#306).
- [_n_a_m_e/fontBuilder] Make ``_n_a_m_e_table.addMultilingualName`` also add
Macintosh (platformID=1) names by default. Added options to ``FontBuilder``
``setupNameTable`` method to optionally disable Macintosh or Windows names.
(#1359, #1431).
- [varLib] Make ``build`` optionally accept a ``DesignSpaceDocument`` object,
instead of a designspace file path. The caller can now set the ``font``
attribute of designspace's sources to a TTFont object, thus allowing to
skip filenames manipulation altogether (#1416, #1425).
- [sfnt] Allow SFNTReader objects to be deep-copied.
- Require typing>=3.6.4 on py27 to fix issue with singledispatch (#1423).
- [designspaceLib/t1Lib/macRes] Fixed some cases where pathlib.Path objects were
not accepted (#1421).
- [varLib] Fixed merging of multiple PairPosFormat2 subtables (#1411).
- [varLib] The default STAT table version is now set to 1.1, to improve
compatibility with legacy applications (#1413).
3.34.2 (released 2018-12-17)
----------------------------
- [merge] Fixed AssertionError when none of the script tables in GPOS/GSUB have
a DefaultLangSys record (#1408, 135a4a1).
3.34.1 (released 2018-12-17)
----------------------------
- [varLib] Work around macOS rendering issue for composites without gvar entry (#1381).
3.34.0 (released 2018-12-14)
----------------------------
- [varLib] Support generation of CFF2 variable fonts. ``model.reorderMasters()``
now supports arbitrary mapping. Fix handling of overlapping ranges for feature
variations (#1400).
- [cffLib, subset] Code clean-up and fixing related to CFF2 support.
- [ttLib.tables.ttProgram] Use raw strings for regex patterns (#1389).
- [fontbuilder] Initial support for building CFF2 fonts. Set CFF's
``FontMatrix`` automatically from unitsPerEm.
- [plistLib] Accept the more general ``collections.Mapping`` instead of the
specific ``dict`` class to support custom data classes that should serialize
to dictionaries.
3.33.0 (released 2018-11-30)
----------------------------
- [subset] subsetter bug fix with variable fonts.
- [varLib.featureVar] Improve FeatureVariations generation with many rules.
- [varLib] Enable sparse masters when building variable fonts:
https://github.com/fonttools/fonttools/pull/1368#issuecomment-437257368
- [varLib.mutator] Add IDEF for GETVARIATION opcode, for handling hints in an
instance.
- [ttLib] Ignore the length of kern table subtable format 0
3.32.0 (released 2018-11-01)
----------------------------
- [ufoLib] Make ``UFOWriter`` a subclass of ``UFOReader``, and use mixins
for shared methods (#1344).
- [featureVars] Fixed normalization error when a condition's minimum/maximum
attributes are missing in designspace ``<rule>`` (#1366).
- [setup.py] Added ``[plot]`` to extras, to optionally install ``matplotlib``,
needed to use the ``fonTools.varLib.plot`` module.
- [varLib] Take total bounding box into account when resolving model (7ee81c8).
If multiple axes have the same range ratio, cut across both (62003f4).
- [subset] Don't error if ``STAT`` has no ``AxisValue`` tables.
- [fontBuilder] Added a new submodule which contains a ``FontBuilder`` wrapper
class around ``TTFont`` that makes it easier to create a working TTF or OTF
font from scratch with code. NOTE: the API is still experimental and may
change in future versions.
3.31.0 (released 2018-10-21)
----------------------------
- [ufoLib] Merged the `ufoLib <https://github.com/unified-font-objects/ufoLib>`__
master branch into a new ``fontTools.ufoLib`` package (#1335, #1095).
Moved ``ufoLib.pointPen`` module to ``fontTools.pens.pointPen``.
Moved ``ufoLib.etree`` module to ``fontTools.misc.etree``.
Moved ``ufoLib.plistlib`` module to ``fontTools.misc.plistlib``.
To use the new ``fontTools.ufoLib`` module you need to install fonttools
with the ``[ufo]`` extra, or you can manually install the required additional
dependencies (cf. README.rst).
- [morx] Support AAT action type to insert glyphs and clean up compilation
of AAT action tables (4a1871f, 2011ccf).
- [subset] The ``--no-hinting`` on a CFF font now also drops the optional
hinting keys in Private dict: ``ForceBold``, ``LanguageGroup``, and
``ExpansionFactor`` (#1322).
- [subset] Include nameIDs referenced by STAT table (#1327).
- [loggingTools] Added ``msg=None`` argument to
``CapturingLogHandler.assertRegex`` (0245f2c).
- [varLib.mutator] Implemented ``FeatureVariations`` instantiation (#1244).
- [g_l_y_f] Added PointPen support to ``_TTGlyph`` objects (#1334).
3.30.0 (released 2018-09-18)
----------------------------
- [feaLib] Skip building noop class PairPos subtables when Coverage is NULL
(#1318).
- [ttx] Expose the previously reserved bit flag ``OVERLAP_SIMPLE`` of
glyf table's contour points in the TTX dump. This is used in some
implementations to specify a non-zero fill with overlapping contours (#1316).
- [ttLib] Added support for decompiling/compiling ``TS1C`` tables containing
VTT sources for ``cvar`` variation table (#1310).
- [varLib] Use ``fontTools.designspaceLib`` to read DesignSpaceDocument. The
``fontTools.varLib.designspace`` module is now deprecated and will be removed
in future versions. The presence of an explicit ``axes`` element is now
required in order to build a variable font (#1224, #1313).
- [varLib] Implemented building GSUB FeatureVariations table from the ``rules``
element of DesignSpace document (#1240, #713, #1314).
- [subset] Added ``--no-layout-closure`` option to not expand the subset with
the glyphs produced by OpenType layout features. Instead, OpenType features
will be subset to only rules that are relevant to the otherwise-specified
glyph set (#43, #1121).
3.29.1 (released 2018-09-10)
----------------------------
- [feaLib] Fixed issue whereby lookups from DFLT/dflt were not included in the
DFLT/non-dflt language systems (#1307).
- [graphite] Fixed issue on big-endian architectures (e.g. ppc64) (#1311).
- [subset] Added ``--layout-scripts`` option to add/exclude set of OpenType
layout scripts that will be preserved. By default all scripts are retained
(``'*'``) (#1303).
3.29.0 (released 2018-07-26)
----------------------------
- [feaLib] In the OTL table builder, when the ``name`` table is excluded
from the list of tables to be build, skip compiling ``featureNames`` blocks,
as the records referenced in ``FeatureParams`` table don't exist (68951b7).
- [otBase] Try ``ExtensionLookup`` if other offset-overflow methods fail
(05f95f0).
- [feaLib] Added support for explicit ``subtable;`` break statements in
PairPos lookups; previously these were ignored (#1279, #1300, #1302).
- [cffLib.specializer] Make sure the stack depth does not exceed maxstack - 1,
so that a subroutinizer can insert subroutine calls (#1301,
https://github.com/googlei18n/ufo2ft/issues/266).
- [otTables] Added support for fixing offset overflow errors occurring inside
``MarkBasePos`` subtables (#1297).
- [subset] Write the default output file extension based on ``--flavor`` option,
or the value of ``TTFont.sfntVersion`` (d7ac0ad).

----------------------------
- [featureVars] Added experimental module to build ``FeatureVariations``
tables. Still needs to be hooked up to ``varLib.build`` (#1240).
- [fixedTools] Added ``otRound`` to round floats to nearest integer towards
positive Infinity. This is now used where we deal with visual data like X/Y
coordinates, advance widths/heights, variation deltas, and similar (#1274,
#1248).
- [subset] Improved GSUB closure memoize algorithm.
- [varLib.models] Fixed regression in model resolution (180124, #1269).
- [feaLib.ast] Fixed error when converting ``SubtableStatement`` to string
(#1275).
- [varLib.mutator] Set ``OS/2.usWeightClass`` and ``usWidthClass``, and
``post.italicAngle`` based on the 'wght', 'wdth' and 'slnt' axis values
(#1276, #1264).
- [py23/loggingTools] Don't automatically set ``logging.lastResort`` handler
on py27. Moved ``LastResortLogger`` to the ``loggingTools`` module (#1277).
3.27.1 (released 2018-06-11)
----------------------------
- [ttGlyphPen] Issue a warning and skip building non-existing components
(https://github.com/googlei18n/fontmake/issues/411).
- [tests] Fixed issue running ttx_test.py from a tagged commit.
3.27.0 (released 2018-06-11)
----------------------------
- [designspaceLib] Added new ``conditionSet`` element to ``rule`` element in
designspace document. Bumped ``format`` attribute to ``4.0`` (previously,
it was formatted as an integer). Removed ``checkDefault``, ``checkAxes``
methods, and any kind of guessing about the axes when the ``<axes>`` element
is missing. The default master is expected at the intersection of all default
values for each axis (#1254, #1255, #1267).
- [cffLib] Fixed issues when compiling CFF2 or converting from CFF when the
font has an FDArray (#1211, #1271).
- [varLib] Avoid attempting to build ``cvar`` table when ``glyf`` table is not
present, as is the case for CFF2 fonts.
- [subset] Handle None coverages in MarkGlyphSets; revert commit 02616ab that
sets empty Coverage tables in MarkGlyphSets to None, to make OTS happy.
- [ttFont] Allow to build glyph order from ``maxp.numGlyphs`` when ``post`` or
``cmap`` are missing.
- [ttFont] Added ``__len__`` method to ``_TTGlyphSet``.
- [glyf] Ensure ``GlyphCoordinates`` never overflow signed shorts (#1230).
- [py23] Added alias for ``itertools.izip`` shadowing the built-in ``zip``.
- [loggingTools] Memoize ``log`` property of ``LogMixin`` class (fbab12).
- [ttx] Impoved test coverage (#1261).
- [Snippets] Addded script to append a suffix to all family names in a font.
- [varLib.plot] Make it work with matplotlib >= 2.1 (b38e2b).
3.26.0 (released 2018-05-03)
----------------------------
- [designspace] Added a new optional ``layer`` attribute to the source element,
and a corresponding ``layerName`` attribute to the ``SourceDescriptor``
object (#1253).
Added ``conditionset`` element to the ``rule`` element to the spec, but not
implemented in designspace reader/writer yet (#1254).
- [varLib.models] Refine modeling one last time (0ecf5c5).
- [otBase] Fixed sharing of tables referred to by different offset sizes
(795f2f9).
- [subset] Don't drop a GDEF that only has VarStore (fc819d6). Set to None
empty Coverage tables in MarkGlyphSets (02616ab).
- [varLib]: Added ``--master-finder`` command-line option (#1249).
- [varLib.mutator] Prune fvar nameIDs from instance's name table (#1245).

(#1234). Added ``kind`` argument to T1Font constructor (c5c161c).
- [ttLib] Added context manager API to ``TTFont`` class, so it can be used in
``with`` statements to auto-close the file when exiting the context (#1232).
3.25.0 (released 2018-04-03)
----------------------------
- [varLib] Improved support-resolution algorithm. Previously, the on-axis
masters would always cut the space. They don't anymore. That's more
consistent, and fixes the main issue Erik showed at TYPO Labs 2017.
Any varfont built that had an unusual master configuration will change
when rebuilt (42bef17, a523a697,
https://github.com/googlei18n/fontmake/issues/264).
- [varLib.models] Added a ``main()`` entry point, that takes positions and
prints model results.
- [varLib.plot] Added new module to plot a designspace's
VariationModel. Requires ``matplotlib``.
- [varLib.mutator] Added -o option to specify output file path (2ef60fa).

- [varLib.models] Convert delta array to floats if values overflows signed
short integer (0055f94).
3.24.2 (released 2018-03-26)
----------------------------
- [otBase] Don't fail during ``ValueRecord`` copy if src has more items.
We drop hinting in the subsetter by simply changing ValueFormat, without
cleaning up the actual ValueRecords. This was causing assertion error if
a variable font was subsetted without hinting and then passed directly to
the mutator for instantiation without first it saving to disk.
3.24.1 (released 2018-03-06)
----------------------------
- [varLib] Don't remap the same ``DeviceTable`` twice in VarStore optimizer
(#1206).
- [varLib] Add ``--disable-iup`` option to ``fonttools varLib`` script,
and a ``optimize=True`` keyword argument to ``varLib.build`` function,
to optionally disable IUP optimization while building varfonts.
- [ttCollection] Fixed issue while decompiling ttc with python3 (#1207).
3.24.0 (released 2018-03-01)
----------------------------
- [ttGlyphPen] Decompose composite glyphs if any components' transform is too
large to fit a ``F2Dot14`` value, or clamp transform values that are
(almost) equal to +2.0 to make them fit and avoid decomposing (#1200,
#1204, #1205).
- [ttx] Added new ``-g`` option to dump glyphs from the ``glyf`` table
splitted as individual ttx files (#153, #1035, #1132, #1202).
- Copied ``ufoLib.filenames`` module to ``fontTools.misc.filenames``, used
for the ttx split-glyphs option (#1202).
- [feaLib] Added support for ``cvParameters`` blocks in Character Variant
feautures ``cv01-cv99`` (#860, #1169).
- [Snippets] Added ``checksum.py`` script to generate/check SHA1 hash of
ttx files (#1197).
- [varLib.mutator] Fixed issue while instantiating some variable fonts
whereby the horizontal advance width computed from ``gvar`` phantom points
could turn up to be negative (#1198).
- [varLib/subset] Fixed issue with subsetting GPOS variation data not
picking up ``ValueRecord`` ``Device`` objects (54fd71f).
- [feaLib/voltLib] In all AST elements, the ``location`` is no longer a
required positional argument, but an optional kewyord argument (defaults
to ``None``). This will make it easier to construct feature AST from
code (#1201).
3.23.0 (released 2018-02-26)
----------------------------
- [designspaceLib] Added an optional ``lib`` element to the designspace as a
whole, as well as to the instance elements, to store arbitrary data in a
property list dictionary, similar to the UFO's ``lib``. Added an optional
``font`` attribute to the ``SourceDescriptor``, to allow operating on
in-memory font objects (#1175).
- [cffLib] Fixed issue with lazy-loading of attributes when attempting to
set the CFF TopDict.Encoding (#1177, #1187).
- [ttx] Fixed regression introduced in 3.22.0 that affected the split tables
``-s`` option (#1188).
- [feaLib] Added ``IncludedFeaNotFound`` custom exception subclass, raised
when an included feature file cannot be found (#1186).
- [otTables] Changed ``VarIdxMap`` to use glyph names internally instead of
glyph indexes. The old ttx dumps of HVAR/VVAR tables that contain indexes
can still be imported (21cbab8, 38a0ffb).
- [varLib] Implemented VarStore optimizer (#1184).
- [subset] Implemented pruning of GDEF VarStore, HVAR and MVAR (#1179).
- [sfnt] Restore backward compatiblity with ``numFonts`` attribute of
``SFNTReader`` object (#1181).
- [merge] Initial support for merging ``LangSysRecords`` (#1180).
- [ttCollection] don't seek(0) when writing to possibly unseekable strems.
- [subset] Keep all ``--name-IDs`` from 0 to 6 by default (#1170, #605, #114).
- [cffLib] Added ``width`` module to calculate optimal CFF default and
nominal glyph widths.
- [varLib] Don’t fail if STAT already in the master fonts (#1166).
3.22.0 (released 2018-02-04)
----------------------------
- [subset] Support subsetting ``endchar`` acting as ``seac``-like components
in ``CFF`` (fixes #1162).
- [feaLib] Allow to build from pre-parsed ``ast.FeatureFile`` object.
Added ``tables`` argument to only build some tables instead of all (#1159,
#1163).
- [textTools] Replaced ``safeEval`` with ``ast.literal_eval`` (#1139).
- [feaLib] Added option to the parser to not resolve ``include`` statements
(#1154).
- [ttLib] Added new ``ttCollection`` module to read/write TrueType and
OpenType Collections. Exports a ``TTCollection`` class with a ``fonts``
attribute containing a list of ``TTFont`` instances, the methods ``save``
and ``saveXML``, plus some list-like methods. The ``importXML`` method is
not implemented yet (#17).
- [unicodeadata] Added ``ot_tag_to_script`` function that converts from
OpenType script tag to Unicode script code.
- Added new ``designspaceLib`` subpackage, originally from Erik Van Blokland's
``designSpaceDocument``: https://github.com/LettError/designSpaceDocument
NOTE: this is not yet used internally by varLib, and the API may be subject
to changes (#911, #1110, LettError/designSpaceDocument#28).
- Added new FontTools icon images (8ee7c32).
- [unicodedata] Added ``script_horizontal_direction`` function that returns
either "LTR" or "RTL" given a unicode script code.

single pairs; emit warning and chose the first value (#1147, #1148).
- [loggingTools] In ``CapturingLogHandler.assertRegex`` method, match the
fully formatted log message.
- [sbix] Fixed TypeError when concatenating str and bytes (#1154).
- [bezierTools] Implemented cusp support and removed ``approximate_fallback``
arg in ``calcQuadraticArcLength``. Added ``calcCubicArcLength`` (#1142).
3.21.2 (released 2018-01-08)
----------------------------
- [varLib] Fixed merging PairPos Format1/2 with missing subtables (#1125).

3.20.1 (released 2017-11-22)
----------------------------
- [unicodedata] Fixed issue with ``script`` and ``script_extension`` functions
returning inconsistent short vs long names. They both return the short four-
letter script codes now. Added ``script_name`` and ``script_code`` functions
to look up the long human-readable script name from the script code, and
viceversa (#1109, #1111).
3.20.0 (released 2017-11-21)
----------------------------
- [unicodedata] Addded new module ``fontTools.unicodedata`` which exports the
same interface as the built-in ``unicodedata`` module, with the addition of
a few functions that are missing from the latter, such as ``script``,
``script_extension`` and ``block``. Added a ``MetaTools/buildUCD.py`` script
to download and parse data files from the Unicode Character Database and
generate python modules containing lists of ranges and property values.
- [feaLib] Added ``__str__`` method to all ``ast`` elements (delegates to the
``asFea`` method).
- [feaLib] ``Parser`` constructor now accepts a ``glyphNames`` iterable
instead of ``glyphMap`` dict. The latter still works but with a pending
deprecation warning (#1104).
- [bezierTools] Added arc length calculation functions originally from
``pens.perimeterPen`` module (#1101).
- [varLib] Started generating STAT table (8af4309). Right now it just reflects
the axes, and even that with certain limitations:
* AxisOrdering is set to the order axes are defined,
* Name-table entries are not shared with fvar.
- [py23] Added backports for ``redirect_stdout`` and ``redirect_stderr``
context managers (#1097).
- [Graphite] Fixed some round-trip bugs (#1093).
3.19.0 (released 2017-11-06)
----------------------------
- [varLib] Try set of used points instead of all points when testing whether to
share points between tuples (#1090).
- [CFF2] Fixed issue with reading/writing PrivateDict BlueValues to TTX file.
Read the commit message 8b02b5a and issue #1030 for more details.
NOTE: this change invalidates all the TTX files containing CFF2 tables
that where dumped with previous verisons of fonttools.
CFF2 Subr items can have values on the stack after the last operator, thus
a ``CFF2Subr`` class was added to accommodate this (#1091).
- [_k_e_r_n] Fixed compilation of AAT kern version=1.0 tables (#1089, #1094)
- [ttLib] Added getBestCmap() convenience method to TTFont class and cmap table
class that returns a preferred Unicode cmap subtable given a list of options
(#1092).

into SVG path descriptions. Copied from Tal Leming's ``ufo2svg.svgPathPen``
https://github.com/typesupply/ufo2svg/blob/d69f992/Lib/ufo2svg/svgPathPen.py
- [reverseContourPen] Added ``ReverseContourPen``, a filter pen that draws
contours with the winding direction reversed, while keeping the starting
point (#1071).
- [filterPen] Added ``ContourFilterPen`` to manipulate contours as a whole
rather than segment by segment.
- [arrayTools] Added ``Vector`` class to apply math operations on an array
of numbers, and ``pairwise`` function to loop over pairs of items in an
iterable.
- [varLib] Added support for building and interpolation of ``cvar`` table
(f874cf6, a25a401).
3.16.0 (released 2017-10-03)
----------------------------
- [head] Try using ``SOURCE_DATE_EPOCH`` environment variable when setting
the ``head`` modified timestamp to ensure reproducible builds (#1063).
See https://reproducible-builds.org/specs/source-date-epoch/

``interpolate_layout`` to allow disabling avar mapping: if False (default),
the location is mapped using the map element of the axes in designspace file;
if True, it is assumed that location is in designspace's internal space and
no mapping is performed (#950, #975).
- [varLib.interpolate_layout] Import designspace-loading logic from varLib.
- [varLib] Fixed bug with recombining PairPosClass2 subtables (81498e5, #914).

instead of 'f' (float) as ``array.array`` typecode (#963, #964).
3.11.0 (released 2017-05-03)
----------------------------
- [t2CharStringPen] Initial support for specialized Type2 path operators:
vmoveto, hmoveto, vlineto, hlineto, vvcurveto, hhcurveto, vhcurveto and
hvcurveto. This should produce more compact charstrings (#940, #403).
- [Doc] Added Sphinx sources for the documentation. Thanks @gferreira (#935).
- [fvar] Expose flags in XML (#932)
- [name] Add helper function for building multi-lingual names (#921)

that are NOT present in the Coverage (1b5e1c4, #939).
- [varLib] Fixed non-deterministic ClassDef order with PY3 (f056c12, #927).
- [feLib] Throw an error when the same glyph is defined in multiple mark
classes within the same lookup (3e3ff00, #453).
3.10.0 (released 2017-04-14)
----------------------------
- [varLib] Added support for building ``avar`` table, using the designspace
``<map>`` elements.
- [varLib] Removed unused ``build(..., axisMap)`` argument. Axis map should
be specified in designspace file now. We do not accept nonstandard axes
if ``<axes>`` element is not present.
- [varLib] Removed "custom" axis from the ``standard_axis_map``. This was
added before when glyphsLib was always exporting the (unused) custom axis.
- [varLib] Added partial support for building ``MVAR`` table; does not
implement ``gasp`` table variations yet.
- [pens] Added FilterPen base class, for pens that control another pen;
factored out ``addComponent`` method from BasePen into a separate abstract
DecomposingPen class; added DecomposingRecordingPen, which records
components decomposed as regular contours.
- [TSI1] Fixed computation of the textLength of VTT private tables (#913).
- [loggingTools] Added ``LogMixin`` class providing a ``log`` property to
subclasses, which returns a ``logging.Logger`` named after the latter.

See, for example, ``feaLib.builder_test.test_extensions`` and
baseClass.feax (#794, fixes #773).
- [feaLib] Added ``feaLib`` command to the 'fonttools' command-line
tool; applies a feature file to a font. ``fonttools feaLib -h`` for
help.

3.3.1 (released 2016-12-15)
---------------------------
- [setup] We no longer use versioneer.py to compute fonttools version
from git metadata, as this has caused issues for some users (#767).
Now we bump the version strings manually with a custom ``release``
command of setup.py script.
3.3.0 (released 2016-12-06)
---------------------------
- [ttLib] Implemented STAT table from OpenType 1.8 (#758)
- [cffLib] Fixed decompilation of CFF fonts containing non-standard
key/value pairs in FontDict (issue #740; PR #744)
- [py23] minor: in ``round3`` function, allow the second argument to be
``None`` (#757)
- The standalone ``sstruct`` and ``xmlWriter`` modules, deprecated
since vesion 3.2.0, have been removed. They can be imported from the
``fontTools.misc`` package.
3.2.3 (released 2016-12-02)
---------------------------
- [py23] optimized performance of round3 function; added backport for
py35 math.isclose() (9d8dacb)

---------------------------
- [OS/2] fix checking ``fsSelection`` bits matching ``head.macStyle``
bits
- [varLib] added ``--build-HVAR`` option to generate ``HVAR`` table for
fonts with TrueType outlines. For ``CFF2``, it is enabled by default.
3.2.0 (released 2016-11-02)
---------------------------
- [varLib] Improve support for OpenType 1.8 Variable Fonts:
- Implement GDEF's VariationStore
- Implement HVAR/VVAR tables
- Partial support for loading MutatorMath .designspace files with
varLib.designspace module
- Add varLib.models with Variation fonts interpolation models
- Implement GSUB/GPOS FeatureVariations
- Initial support for interpolating and merging OpenType Layout tables
(see ``varLib.interpolate_layout`` and ``varLib.merger`` modules)
- [API change] Change version to be an integer instead of a float in
XML output for GSUB, GPOS, GDEF, MATH, BASE, JSTF, HVAR, VVAR, feat,
hhea and vhea tables. Scripts that set the Version for those to 1.0
or other float values also need fixing. A warning is emitted when
code or XML needs fix.
- several bug fixes to the cffLib module, contributed by Adobe's
@readroberts
- The XML output for CFF table now has a 'major' and 'minor' elements
for specifying whether it's version 1.0 or 2.0 (support for CFF2 is
coming soon)
- [setup.py] remove undocumented/deprecated ``extra_path`` Distutils
argument. This means that we no longer create a "FontTools" subfolder
in site-packages containing the actual fontTools package, as well as
the standalone xmlWriter and sstruct modules. The latter modules are
also deprecated, and scheduled for removal in upcoming releases.
Please change your import statements to point to from fontTools.misc
import xmlWriter and from fontTools.misc import sstruct.
- [scripts] Add a 'fonttools' command-line tool that simply runs
``fontTools.*`` sub-modules: e.g. ``fonttools ttx``,
``fonttools subset``, etc.
- [hmtx/vmts] Read advance width/heights as unsigned short (uint16);
automatically round float values to integers.
- [ttLib/xmlWriter] add 'newlinestr=None' keyword argument to
``TTFont.saveXML`` for overriding os-specific line endings (passed on
to ``XMLWriter`` instances).
- [versioning] Use versioneer instead of ``setuptools_scm`` to
dynamically load version info from a git checkout at import time.
- [feaLib] Support backslash-prefixed glyph names.
3.1.2 (released 2016-09-27)
---------------------------

``--with-zopfli`` option to use Zopfli to compress WOFF 1.0 fonts.
- [subset] Support subsetting 'COLR'/'CPAL' and 'CBDT'/'CBLC' color
fonts tables, and 'gvar' table for variation fonts.
- [Snippets] Add ``symfont.py``, for symbolic font statistics analysis;
interpolatable.py, a preliminary script for detecting interpolation
errors; ``{merge,dump}_woff_metadata.py``.
- [classifyTools] Helpers to classify things into classes.
- [CI] Run tests on Windows, Linux and macOS using Appveyor and Travis
CI; check unit test coverage with Coverage.py/Coveralls; automatic
deployment to PyPI on tags.
- [loggingTools] Use Python built-in logging module to print messages.

- Add VDMX table converter
- Load all OpenType sub-structures lazily
- Add support for cmap format 13.
- Add pyftmerge tool
- Update to Unicode 6.3.0d3
- Add pyftinspect tool
- Add support for Google CBLC/CBDT color bitmaps, standard EBLC/EBDT
embedded bitmaps, and ``SVG`` table (thanks to Read Roberts at Adobe)
- Add support for loading, saving and ttx'ing WOFF file format
- Add support for Microsoft COLR/CPAL layered color glyphs
- Support PyPy
- Support Jython, by replacing numpy with array/lists modules and
removed it, pure-Python StringIO, not cStringIO
- Add pyftsubset and Subsetter object, supporting CFF and TTF
- Add to ttx args for -q for quiet mode, -z to choose a bitmap dump
format

2.3 (released 2009-11-08)
-------------------------
- TrueType Collection (TTC) support
- Python 2.6 support
- Update Unicode data to 5.2.0
- Couple of bug fixes
2.2 (released 2008-05-18)
-------------------------
- ClearType support
- cmap format 1 support
- PFA font support
- Switched from Numeric to numpy
- Update Unicode data to 5.1.0
- Update AGLFN data to 1.6
- Many bug fixes
2.1 (released 2008-01-28)
-------------------------
- Many years worth of fixes and features
2.0b2 (released 2002-??-??)
---------------------------
- Be "forgiving" when interpreting the maxp table version field:
interpret any value as 1.0 if it's not 0.5. Fixes dumping of these
GPL fonts: http://www.freebsd.org/cgi/pds.cgi?ports/chinese/wangttf
- Fixed ttx -l: it turned out this part of the code didn't work with
Python 2.2.1 and earlier. My bad to do most of my testing with a
different version than I shipped TTX with :-(
- Fixed bug in ClassDef format 1 subtable (Andreas Seidel bumped into
this one).
2.0b1 (released 2002-09-10)
---------------------------
- Fixed embarrassing bug: the master checksum in the head table is now
calculated correctly even on little-endian platforms (such as Intel).
- Made the cmap format 4 compiler smarter: the binary data it creates
is now more or less as compact as possible. TTX now makes more
compact data than in any shipping font I've tested it with.
- Dump glyph names as a separate "GlyphOrder" pseudo table as opposed
to as part of the glyf table (obviously needed for CFF-OTF's).
- Added proper support for the CFF table.
- Don't barf on empty tables (questionable, but "there are font out
there...")
- When writing TT glyf data, align glyphs on 4-byte boundaries. This
seems to be the current recommendation by MS. Also: don't barf on
fonts which are already 4-byte aligned.
- Windows installer contributed bu Adam Twardoch! Yay!
- Changed the command line interface again, now by creating one new
tool replacing the old ones: ttx It dumps and compiles, depending on
input file types. The options have changed somewhat.
- The -d option is back (output dir)
- ttcompile's -i options is now called -m (as in "merge"), to avoid
clash with dump's -i.
- The -s option ("split tables") no longer creates a directory, but
instead outputs a small .ttx file containing references to the
individual table files. This is not a true link, it's a simple file
name, and the referenced file should be in the same directory so
ttcompile can find them.
- compile no longer accepts a directory as input argument. Instead it
can parse the new "mini-ttx" format as output by "ttx -s".
- all arguments are input files
- Renamed the command line programs and moved them to the Tools
subdirectory. They are now installed by the setup.py install script.
- Added OpenType support. BASE, GDEF, GPOS, GSUB and JSTF are (almost)
fully supported. The XML output is not yet final, as I'm still
considering to output certain subtables in a more human-friendly
manner.
- Fixed 'kern' table to correctly accept subtables it doesn't know
about, as well as interpreting Apple's definition of the 'kern' table
headers correctly.
- Fixed bug where glyphnames were not calculated from 'cmap' if it was
(one of the) first tables to be decompiled. More specifically: it
cmap was the first to ask for a glyphID -> glyphName mapping.
- Switched XML parsers: use expat instead of xmlproc. Should be faster.
- Removed my UnicodeString object: I now require Python 2.0 or up,
which has unicode support built in.
- Removed assert in glyf table: redundant data at the end of the table
is now ignored instead of raising an error. Should become a warning.
- Fixed bug in hmtx/vmtx code that only occured if all advances were
equal.
- Fixed subtle bug in TT instruction disassembler.
- Couple of fixes to the 'post' table.
- Updated OS/2 table to latest spec.
1.0b1 (released 2001-08-10)
---------------------------
- Reorganized the command line interface for ttDump.py and
ttCompile.py, they now behave more like "normal" command line tool,
in that they accept multiple input files for batch processing.
- ttDump.py and ttCompile.py don't silently override files anymore, but
ask before doing so. Can be overridden by -f.
- Added -d option to both ttDump.py and ttCompile.py.
- Installation is now done with distutils. (Needs work for environments
without compilers.)
- Updated installation instructions.
- Added some workarounds so as to handle certain buggy fonts more
gracefully.
- Updated Unicode table to Unicode 3.0 (Thanks Antoine!)
- Included a Python script by Adam Twardoch that adds some useful stuff
to the Windows registry.
- Moved the project to SourceForge.
1.0a6 (released 2000-03-15)
---------------------------
- Big reorganization: made ttLib a subpackage of the new fontTools
package, changed several module names. Called the entire suite
"FontTools"
- Added several submodules to fontTools, some new, some older.
- Added experimental CFF/GPOS/GSUB support to ttLib, read-only (but XML
dumping of GPOS/GSUB is for now disabled)
- Fixed hdmx endian bug
- Added -b option to ttCompile.py, it disables recalculation of
bounding boxes, as requested by Werner Lemberg.
- Renamed tt2xml.pt to ttDump.py and xml2tt.py to ttCompile.py
- Use ".ttx" as file extension instead of ".xml".
- TTX is now the name of the XML-based *format* for TT fonts, and not
just an application.
1.0a5
-----
Never released
- More tables supported: hdmx, vhea, vmtx
1.0a3 & 1.0a4
-------------
Never released
- fixed most portability issues
- retracted the "Euro_or_currency" change from 1.0a2: it was
nonsense!
1.0a2 (released 1999-05-02)
---------------------------
- binary release for MacOS
- genenates full FOND resources: including width table, PS font name
info and kern table if applicable.
- added cmap format 4 support. Extra: dumps Unicode char names as XML
comments!
- added cmap format 6 support
- now accepts true type files starting with "true" (instead of just
0x00010000 and "OTTO")
- 'glyf' table support is now complete: I added support for composite
scale, xy-scale and two-by-two for the 'glyf' table. For now,
component offset scale behaviour defaults to Apple-style. This only
affects the (re)calculation of the glyph bounding box.
- changed "Euro" to "Euro_or_currency" in the Standard Apple Glyph
order list, since we cannot tell from the 'post' table which is
meant. I should probably doublecheck with a Unicode encoding if
available. (This does not affect the output!)
Fixed bugs: - 'hhea' table is now recalculated correctly - fixed wrong
assumption about sfnt resource names
1.0a1 (released 1999-04-27)
