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.

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.

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.

This package provides the sfd2ufo command, a converter from FontForge’s SFD fonts to UFO fonts.

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).

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 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.

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.

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

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

Build an OpenType Collection font file from two or more OpenType font files.

otf2ttf

Converts OpenType-CFF fonts to TrueType.

rotatefont

Apply a Postscript transform matrix to the source font files.

sfntdiff

Low-level comparison of two OpenType font files.

sfntedit

Support table-editing, listing, and checksumming options on sfnt-formatted files such as OpenType Format (OTF) or TrueType.

spot

Dump sfnt data from plain files or Macintosh resource files.

ttfcomponentizer

Take in a TrueType font and look for a UFO font stored in the same directory. Use the UFO's components data to compose matching TrueType glyphs.

ttfdecomponentizer

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.

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.

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).

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.

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

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.

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

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.

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

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

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

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.

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