:mod:`.ttLib.ttFont` is the primary fontTools interface for
|
|
|
|
|
inspecting, constructing, or deconstructing TrueType and OpenType
|
|
|
|
|
fonts.
|
|
|
|
|
|
|
|
|
|
The :class:`fontTools.ttLib.ttFont.TTFont` class provides access to
|
|
|
|
|
font-level data, including font metrics, substitution and positioning
|
|
|
|
|
features, and metadata, through a set of :doc:`table converters
|
|
|
|
|
</ttLib/tables>`. A :class:`.TTFont` may be instantiated from a single
|
|
|
|
|
font file, or it may be a member of a
|
|
|
|
|
:class:`.TTCollection`. :class:`.TTFont` objects can also be
|
|
|
|
|
constructed from scratch.
|
|
|
|
|
|
|
|
|
|
In addition to font-wide data, :mod:`.ttLib.ttFont` provides access to
|
|
|
|
|
individual glyphs through the :class:`.TTFont` object's
|
|
|
|
|
``glyphSet[]``. This is a dict-like object that is indexed by glyph
|
|
|
|
|
names. Users can use the glyphSet to interact with each glyph's
|
|
|
|
|
contours, components, points, and glyph metrics.
|
|
|
|
|
|
|
|
|
|
These glyph objects also implement the :doc:`Pen Protocol
|
|
|
|
|
</pens/index>` by providing ``.draw()`` and ``.drawPoints()``
|
|
|
|
|
methods. See the :doc:`pens </pens/index>` package documenation
|
|
|
|
|
for more.
