Raph Levien's Spiro package as a library. A mechanism for drawing smooth contours with constant curvature at the spline joins.

This package provides a set of objects for performing fast font, glyph, etc. mathematical operations on font data.

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

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

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.

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.

This package provides Python bindings for the Path Ops module of the Skia library, performing boolean operations on paths (intersection, union, difference, xor).

FontForge allows you to create and modify postscript, truetype and opentype fonts. You can save fonts in many different outline formats, and generate bitmaps.

Python wrapper for the OpenType Sanitizer library.

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.

FontParts is an API for interacting with the parts of fonts during the font development process. FontParts is the successor of RoboFab.

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

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

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 library can read Open Type Layout Tables from an OTF file. Currently these tables are supported; head, name, cmap, GDEF, GSUB, and GPOS. It can convert a Unicode character sequence to a glyph code sequence by using the above tables.

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

ufo2ft (UFO to FontTools) is a fork of ufo2fdk intended to leverage FontTools (a Python library) rather than the Adobe Font Development Kit for OpenType (AFDKO), a set of C libraries/utilities so that it can be more easily extended. Like ufo2fdk, its primary purpose is to generate OpenType font binaries from Unified Font Objects (UFOs).

GNU fontopia is an easy-to-use, text-based, console font editor. You can edit the fonts that your GNU/Linux kernel is using to display your text on text- based (vs graphical) terminals.

ttfautohint provides a 99% automated hinting process and a platform for finely hand-hinting the last 1%. It is ideal for web fonts and supports many scripts.

TTF2PT1 provides tools to convert most TrueType fonts (or other formats supported by the FreeType library) to an Adobe Type 1 .pfa or .pfb file. Another use is as a hinting engine: feed it an unhinted or poorly hinted Adobe Type 1 font through the FreeType library and get it back with freshly generated hints. The files produced by default are in human-readable form, which further needs to be encoded with t1utilities to work with most software requiring Type 1 fonts.

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.

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.
