<docsection name="xftfonts">
<doc xml:space="preserve">The Xft library is a library for displaying fonts on the X window
system; internally it uses the fontconfig library to locate font
files, and the FreeType library to load and render fonts. The
Xft backend is the recommended Pango font backend for screen
display with X. (The <link linkend="pango-Cairo-Rendering">Cairo back end</link> is another possibility.)
Using the Xft backend is generally straightforward;
pango_xft_get_context() creates a context for a specified display
and screen. You can then create a #PangoLayout with that context
and render it with pango_xft_render_layout(). At a more advanced
level, the low-level fontconfig options used for rendering fonts
can be affected using pango_xft_set_default_substitute(), and
pango_xft_substitute_changed().
A range of functions for drawing pieces of a layout, such as
individual layout lines and glyphs strings are provided. You can also
directly create a #PangoXftRenderer. Finally, in some advanced cases, it
is useful to derive from #PangoXftRenderer. Deriving from
#PangoXftRenderer is useful for two reasons. One reason is be to
support custom attributes by overriding #PangoRendererClass virtual
functions like 'prepare_run' or 'draw_shape'. The reason is to
customize exactly how the final bits are drawn to the destination by
overriding the #PangoXftRendererClass virtual functions
'composite_glyphs' and 'composite_trapezoids'.</doc>
