    <title>Introduction to Gdk Pixbuf</title>

    <para>
      The <application>Gdk Pixbuf</application> is a toolkit for image
      loading and pixel buffer manipulation. It is used by
      <application>GTK+ 2</application> and <application>GTK+ 3</application> to
      load and manipulate images. In the past it was distributed as part of
      <application>GTK+ 2</application> but it was split off into a separate
      package in preparation for the change to <application>GTK+ 3</application>.
