eb2394d143012432b73b8633ed632726 pango-1.24.0.tar.gz
This is a stable release providing new functionality as compared to
Pango-1.22, while maintaining source and binary compatibility. However,
the PangoFc backend API has changed slightly. Projects subclassing PangoFc
are advised to review the changed API.
The major change since 1.22 is an overhaul of the internal caching of the
PangoFc fontmap implementation. The new code is much faster and more memory
efficient. This, combined with other optimizations available in this release,
drastically reduce Pango's overhead on Linux systems.
By popular request, pango-view now can save to PS, EPS, PDF, and SVG, and
the bug with "pango-view -q" requiring an X connection is also fixed. These
make pango-view a much more usable tool. It now even ships with a man page.
See the NEWS file for an extensive list of improvements.
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 (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 1.24 depends on version 2.17.3 or newer of the GLib library and
version 1.7.6 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/ and
http://cairographics.org/ respectively.
