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.

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.

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

This package provides two tools:

sfnt2woff

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.

tx

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

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

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.

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.

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.
