The Graphite system consists of:

  • Graphite Description Language (GDL) - a rule-based programming language that is used to describe the behavior of a writing system
  • the Graphite compiler - used to compile the GDL program along with a font to generate the Graphite-enabled version of the font
  • the Graphite engine - uses the Graphite font to assist a text-processing application in performing text layout

The Graphite2 engine represents a rework of the original engine developed for the Graphite package. Implementation began in 2010. It is the package used by LibreOffice 3.4 (and later) and Firefox 11 (and later), and can be integrated into applications on Android versions 2.2 - 2.3.4.

The Graphite2 engine can be downloaded from the ↗ GitHub release page.

The source code is located on GitHub: ↗ https://github.com/silnrsi/graphite

The GitHub repository includes a ↗ manual for integrating Graphite2 into an application
