About Pango

Pango is a library for layout and rendering of text, with an emphasis
on internationalization. Pango can be used anywhere that text layout
is needed, though most of the work on Pango so far has been done in
the context of the GTK+ widget toolkit. Pango forms the core of text
and font handling for GTK+-2.x.

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 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, rendering via Cairo.

The integration 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 1.21 depends on version 2.14.0 or newer of the GLib
library and version 1.6.4 or newer of the cairo library (if the
cairo backend is desired); more information about GLib and cairo
