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

Potrace is a tool for tracing a bitmap, which means, transforming a bitmap into a smooth, scalable image. The input is a bitmap (PBM, PGM, PPM, or BMP format), and the default output is an encapsulated PostScript file (EPS). A typical use is to create EPS files from scanned data, such as company or university logos, handwritten notes, etc. The resulting image is not "jaggy" like a bitmap, but smooth. It can then be rendered at any resolution.

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

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.

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

This package contains a commandline wrapper around OpenTypeUtilities.cpp from Chromium, used to make EOT (Embeddable Open Type) files from TTF (TrueType/OpenType Font) files.

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

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.

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.

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.

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.

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

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.

Python wrapper for the OpenType Sanitizer library.

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

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.

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.

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.

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.

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.

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

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