<p>
These functions provide support for drawing points, lines, arcs and text
onto what are called 'drawables'. Drawables, as the name suggests, are things
which support drawing onto them, and are either <a class="link" href="gdk-Windows.html#GdkWindow"><span class="type">GdkWindow</span></a> or <a class="link" href="gdk-Bitmaps-and-Pixmaps.html#GdkPixmap"><span class="type">GdkPixmap</span></a>
objects.
</p>
<p>
Many of the drawing operations take a <a class="link" href="gdk-Graphics-Contexts.html#GdkGC"><span class="type">GdkGC</span></a> argument, which represents a
graphics context. This <a class="link" href="gdk-Graphics-Contexts.html#GdkGC"><span class="type">GdkGC</span></a> contains a number of drawing attributes such
as foreground color, background color and line width, and is used to reduce
the number of arguments needed for each drawing operation. See the
<a class="link" href="gdk-Graphics-Contexts.html" title="Graphics Contexts">Graphics Contexts</a> section for
more information.

<p><a name="pango-data-structures"></a>
Some of the drawing operations take Pango data structures like <a
href="/usr/share/gtk-doc/html/pango/pango-Text-Processing.html#PangoContext"
><span class="type">PangoContext</span></a>,
<a
href="/usr/share/gtk-doc/html/pango/pango-Layout-Objects.html#PangoLayout"
><span class="type">PangoLayout</span></a> or <a
href="/usr/share/gtk-doc/html/pango/pango-Layout-Objects.html#PangoLayoutLine"
><span class="type">PangoLayoutLine</span></a> as arguments. If you're using GTK+, the ususal 
way to obtain these structures is via <a
href="/usr/share/gtk-doc/html/gtk/GtkWidget.html#gtk-widget-create-pango-context"
><code class="function">gtk_widget_create_pango_context()</code></a> or
<a
href="/usr/share/gtk-doc/html/gtk/GtkWidget.html#gtk-widget-create-pango-layout"
><code class="function">gtk_widget_create_pango_layout()</code></a>.
