<a name="pango-Xft-Fonts-and-Rendering.description"></a><h2>Description</h2>
<p>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 <a class="link" href="pango-Cairo-Rendering.html" title="Cairo Rendering">Cairo back end</a> is another possibility.)</p>
<p>Using the Xft backend is generally straightforward;
<a class="link" href="pango-Xft-Fonts-and-Rendering.html#pango-xft-get-context" title="pango_xft_get_context ()"><code class="function">pango_xft_get_context()</code></a> creates a context for a specified display
and screen. You can then create a <a class="link" href="pango-Layout-Objects.html#PangoLayout"><span class="type">PangoLayout</span></a> with that context
and render it with <a class="link" href="pango-Xft-Fonts-and-Rendering.html#pango-xft-render-layout" title="pango_xft_render_layout ()"><code class="function">pango_xft_render_layout()</code></a>. At a more advanced
level, the low-level fontconfig options used for rendering fonts
can be affected using <a class="link" href="pango-Xft-Fonts-and-Rendering.html#pango-xft-set-default-substitute" title="pango_xft_set_default_substitute ()"><code class="function">pango_xft_set_default_substitute()</code></a>, and
<a class="link" href="pango-Xft-Fonts-and-Rendering.html#pango-xft-substitute-changed" title="pango_xft_substitute_changed ()"><code class="function">pango_xft_substitute_changed()</code></a>.</p>
<p>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 <a class="link" href="pango-Xft-Fonts-and-Rendering.html#PangoXftRenderer"><span class="type">PangoXftRenderer</span></a>. Finally, in some advanced cases, it
is useful to derive from <a class="link" href="pango-Xft-Fonts-and-Rendering.html#PangoXftRenderer"><span class="type">PangoXftRenderer</span></a>. Deriving from
<a class="link" href="pango-Xft-Fonts-and-Rendering.html#PangoXftRenderer"><span class="type">PangoXftRenderer</span></a> is useful for two reasons. One reason is be to
support custom attributes by overriding <a class="link" href="PangoRenderer.html#PangoRendererClass" title="struct PangoRendererClass"><span class="type">PangoRendererClass</span></a> 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 <a class="link" href="pango-Xft-Fonts-and-Rendering.html#PangoXftRendererClass" title="struct PangoXftRendererClass"><span class="type">PangoXftRendererClass</span></a> virtual functions
'composite_glyphs' and 'composite_trapezoids'.</p>
