The OpenType Sanitizer (OTS) parses and serializes OpenType files (OTF, TTF) and WOFF and WOFF2 font files, validating them and sanitizing them as it goes.

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.

Freetype is a library that can be used by applications to access the contents of font files. It provides a uniform interface to access font files. It supports both bitmap and scalable formats, including TrueType, OpenType, Type1, CID, CFF, Windows FON/FNT, X11 PCF, and others. It supports high-speed anti-aliased glyph bitmap generation with 256 gray levels.

Raqm is a small library that encapsulates the logic for complex text layout and provides a convenient API.

It currently provides bidirectional text support (using FriBiDi), shaping (using HarfBuzz), and proper script itemization. As a result, Raqm can support most writing systems covered by Unicode.

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.

This package provides the autohinter command that can be used to hint PostScript fonts. A Python wrapper is also included.

bdf2sfd is a BDF to SFD converter, allowing to vectorize bitmap fonts. It works by converting each pixel of a glyph to a polygon, which produces large and unoptimized SFD files that should be post-processed using FontForge.

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

Nototools is a Python package containing Python scripts used to maintain the Noto Fonts project.

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.

FontoBene-Qt is a header-only library to parse FontoBene stroke fonts with C++11/Qt.

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.

This package provides a bridge from Glyphs source files (.glyphs) to UFOs and DesignSpace files via defcon and designspaceLib.

This package provides a tool that can be used to make font samples that show coverage of the font and are similar in appearance to Unicode Charts. It was developed for use with DejaVu Fonts project.

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.

FontoBene-Qt is a header-only library to parse FontoBene stroke fonts with C++11/Qt.

Wrap is a command line tool that is able to convert Fountain files into a correctly formatted screen- or stageplay as an HTML or a PDF. It supports standard Fountain, but also has some custom syntax extensions such as translated keywords and acts.

This package provides a collection of Python classes implementing the pen protocol for manipulating glyphs.

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 two tools:

sfnt2woff

Converts OpenType fonts to WOFF fonts

woff2sfnt

Converts WOFF fonts to OpenType fonts

LibUniNamesList holds www.unicode.org Nameslist.txt data which can be useful for programs that need Unicode "Names", "Annotations", and block definitions.

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.

The Adobe Font Development Kit for OpenType (AFDKO) is a set of tools for building OpenType font (OTF) files from PostScript and TrueType font data. It includes the following commands:

buildcff2vf

Assemble a CFF2 variable font from a .designspace file.

buildmasterotfs

Build master source OpenType/CFF fonts from a .designspace file and UFO master source fonts.

charplot

dtdigiplotdtfontplotdtfontsetplotdthintplotdtwaterfallplot

Aliases for the corresponding options of the proofpdf command.

checkoutlinesufo

Perform outline quality checks. It can also remove path overlaps.

comparefamily

Look in a specific directory, examine and report on all the OpenType fonts found.

type1

dtdetype1

Compile and decompile, respectively, a Type 1 font to and from a plain-text representation.

makeinstancesufo

Generate UFO font instances from a set of master UFO fonts.

makeotfexe

Read all the font data and build the final OpenType font.

makeotf

This command can be used to prepare the input files needed by makeotfexe.

mergefonts

Merge one or more fonts into a parent font.

otc2otf

Extract all OpenType fonts from the parent OpenType Collection font.

otf2otc

Take in a TrueType font and decompose any composite glyphs into simple glyphs.

ttxn

Make a normalized dump of the font, or of selected tables.

tx

The tx (Type eXchange) is a test harness for the CoreType libraries but also provides many useful font conversion and analysis facilities.
