Defcon is a set of UFO based objects optimized for use in font editing applications. The objects are built to be lightweight, fast and flexible. The objects are very bare-bones and they are not meant to be end-all, be-all objects. Rather, they are meant to provide base functionality so that you can focus on your application’s behavior, not object observing or maintaining cached data. Defcon implements UFO3 as described by the UFO font format.

Fontconfig can discover new fonts when installed automatically; perform font name substitution, so that appropriate alternative fonts can be selected if fonts are missing; identify the set of fonts required to completely cover a set of languages; have GUI configuration tools built as it uses an XML-based configuration file; efficiently and quickly find needed fonts among the set of installed fonts; be used in concert with the X Render Extension and FreeType to implement high quality, anti-aliased and subpixel rendered text on a display.

Font Manager is intended to provide a way for users to easily manage desktop fonts, without having to resort to command-line tools or editing configuration files by hand. While designed primarily with the GNOME Desktop Environment in mind, it should work well with other GTK desktop environments.

This Python package processes and generates instances for UFO files, glyphs and other data. It can, among other things:

• Collect source materials.

• Provide mutators for specific glyphs, font info, kerning so that other tools can generate partial instances.

• Support designspace format 4 with layers.

• Apply avar-like designspace bending.

• Apply rules.

• Generate actual UFO instances in formats 2 and 3.

• Round geometry as requested.

The purpose of the ufonormalizer command is to provide a standard formatting so that updates to UFO data can be usefully versioned. Examples of formatting applied by ufoNormalizer include:

• Changing floating-point numbers to integers where it doesn't alter the value (e.g. x="95.0" becomes x="95")

• Rounding floating-point numbers to 10 digits

• Formatting XML with tabs rather than spaces.

Beziers provides a variety of classes for constructing, manipulating and drawing Bezier curves and paths. Principally designed for font design software, it allows you to join, split, offset, and perform many other operations on paths.

LCDF Typetools comprises several programs for manipulating PostScript Type 1, Type 1 Multiple Master, OpenType, and TrueType fonts. These tools are cfftot1, mmafm, mmpfb, otfinfo, otftotfm, t1dotlessj, t1lint, t1rawfm, t1reencode, t1testpage and ttftotype42.

TECkit is a low-level toolkit intended to be used by other applications that need to perform encoding conversions (e.g., when importing legacy data into a Unicode-based application). The primary component of the TECkit package is therefore a library that performs conversions; this is the "TECkit engine". The engine relies on mapping tables in a specific binary format (for which documentation is available); there is a compiler that creates such tables from a human-readable mapping description (a simple text file).

To facilitate the development and testing of mapping tables for TECkit, several applications are also included in the current package; these include simple tools for applying conversions to plain-text and Standard Format files, as well as both command-line and simple GUI versions of the TECkit compiler. However, it is not intended that these tools will be the primary means by which end users perform conversions, and they have not been designed, tested, and debugged to the extent that general-purpose applications should be.

This library provides functions which take in UFO objects (such as Defcon Fonts or Robofab RFonts) and converts any cubic curves to quadratic. The most useful function is probably fonts_to_quadratic.

The ufoLib2 Python library is meant to be a thin representation of the Unified Font Object (UFO) version 3 data model, intended for programmatic manipulation and fast batch processing of UFOs. It resembles the defcon library, but does without notifications, the layout engine and other support classes. Where useful and possible, ufoLib2 tries to be API-compatible with defcon.

This package provides an API with data about glyph sets for many different scripts and languages.

This package contains the font data used by the test suite of the psautohint package.

Graphite2 is a reimplementation of the SIL Graphite text processing engine. Graphite is a smart font technology designed to facilitate the process known as shaping. This process takes an input Unicode text string and returns a sequence of positioned glyphids from the font.
