Pango is designed to be modular; the core Pango layout engine can be used with different font backends. There are three basic backends, with multiple options for rendering（翻译, 表现）with each.
Client side fonts using the FreeType and fontconfig libraries. Rendering can be with with Cairo or Xft libraries, or directly to an in-memory buffer with no additional libraries.
- Native fonts on Microsoft Windows using Uniscribe for complex-text handling. Rendering can be done via Cairo or directly using the native Win32 API.
- Native fonts on MacOS X using ATSUI for complex-text handling, rendering via Cairo.
The integration（综合, 与环境协调的行为, 集成）of Pango with Cairo () provides a complete solution with high quality text handling and graphics rendering.
Dynamically loaded modules then handle text layout for particular combinations of script and font backend. Pango ships with a wide selection of modules, including modules for Hebrew, Arabic, Hangul, Thai, and a number of Indic scripts. Virtually all of the world's major scripts are supported.
As well as the low level layout rendering routines, Pango includes PangoLayout, a high level driver for laying out entire blocks of text, and routines to assist in editing internationalized text.
Pango depends on 2.x series of the GLib library; more information about GLib can be found at .
