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.

WOFF2 provides libraries and tools to handle the Web Open Font Format (WOFF).

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

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.

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 collection of Python classes implementing the pen protocol for manipulating glyphs.

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

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.

It supports high-speed anti-aliased glyph bitmap generation with 256 gray levels.

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

Freetype Python provides bindings for the FreeType library. Only the high-level API is bound.

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 provides two tools:

sfnt2woff

Converts OpenType fonts to WOFF fonts

woff2sfnt

Converts WOFF fonts to OpenType fonts

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

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.

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.

This package provides the cffsubr command, a Compact Font Format (CFF) subroutinizer based on the Adobe Font Development Kit for OpenType (AFDKO) tx tool.

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.

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.

statmake takes a user-written Stylespace that defines OpenType STAT information for an entire font family and then (potentially subsets and) applies it to a specific variable font. This spares users from having to deal with raw TTX dumps and juggling with nameIDs.

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.

Boolean operations on paths which uses a super fast polygon clipper library by Angus Johnson.

T1lib is a library for generating/rasterising bitmaps from Type 1 fonts. It is based on the code of the X11 rasteriser of the X11 project.

The bitmaps created by t1lib are returned in a data structure with type GLYPH. This special GLYPH-type is also used in the X11 window system to describe character bitmaps. It contains the bitmap data as well as some metric information. But t1lib is in itself entirely independent of the X11-system or any other graphical user interface.
