Posted on: 05/31/2007 08:42 AM
Pango-1.17.1 is now available for download at: http://download.gnome.org/sources/pango/1.17/
This is the a development release in a series leading to Pango-1.18.0, which will be released just in time for GNOME-2.20.
* This is unstable development release. While it has had fairly extensive testing, there are likely bugs remaining to be found. This release should not be used in production.
* Installing this version will overwrite your existing copy of Pango. If you have problems, you'll need to reinstall Pango-1.16.x
* Bugs should be reported to http://bugzilla.gnome.org.
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 (http://cairographics.org) 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.
More information about Pango is available from http://www.pango.org/.
Bugs should be reported to http://bugzilla.gnome.org.
Pango 1.17 depends on version 2.12.0 or newer of the GLib library and version 1.2.6 or newer of the cairo library (if the cairo backend is desired); more information about GLib and cairo can be found at http://www.gtk.org/
Overview of changes between 1.17.0 and 1.17.1

- Added N'Ko support to the Arabic module. [Eugeniy Meshcheryakov]
- Small Indic module fix for Malayalam.
- Fixed font metrics returned by the ATSUI backend. [Richard Hult]
- Make itemization use pango_language_get_default() if context has no language set on it. Ditto for pango_context_get_metrics() if both input language and context language are NULL.
- Improved documentation on vertical text, also added stability note to those parts of Pango API that are not indefinitely stable (shaper and language engine APIs).
- Misc bug fixes.
- New OpenType engine API:
