><P
>This module defines <TT
><A HREF="Graphics-Rendering-Pango-Context.html#t%3APangoContext"
>PangoContext</A
></TT
>s,
 an environment that provides information on available fonts,
 internationalization and output capabilities of the medium. Given
 such a context, text can be rendered into strings of glyphs (see
 Graphics.Rendering.Pango.Rendering) or, at a more abstract level, using
 layouts (see Graphics.Rendering.Pango.Layout.Layout).
</P
><UL
><LI
> A <TT
><A HREF="Graphics-Rendering-Pango-Context.html#t%3APangoContext"
>PangoContext</A
></TT
> is a prerequisite for all text rendering functions.
 A context can be created from scratch or, more conveniently, by using
 default settings that are already used in the application. When text
 is rendered through Gdk, use
 Graphics.UI.Gtk.Abstract.Widget.widgetCreatePangoContext, if you use
 the Cairo rendering engine, a new context can be acquired using
 Graphics.Rendering.Cairo.cairoCreateContext.
</LI
><LI
> The properties of a <TT
><A HREF="Graphics-Rendering-Pango-Context.html#t%3APangoContext"
>PangoContext</A
></TT
> can be changed which, in turn, has
 an effect on how text is rendered. To reflect such a change in the
 rendered text, call Graphics.Rendering.Pango.Layout.layoutContextChanged.
