<p>
GooCanvasPath represents a path item, which is a series of one or more
lines, bezier curves, or elliptical arcs.
</p>
<p>
It is a subclass of <a class="link" href="GooCanvasItemSimple.html" title="GooCanvasItemSimple"><span class="type">GooCanvasItemSimple</span></a> and so inherits all of the style
properties such as "stroke-color", "fill-color" and "line-width".
</p>
<p>
It also implements the <a class="link" href="goocanvas-goocanvasitem.html#GooCanvasItem"><span class="type">GooCanvasItem</span></a> interface, so you can use the
<a class="link" href="goocanvas-goocanvasitem.html#GooCanvasItem"><span class="type">GooCanvasItem</span></a> functions such as <a class="link" href="goocanvas-goocanvasitem.html#goo-canvas-item-raise"><code class="function">goo_canvas_item_raise()</code></a> and
<a class="link" href="goocanvas-goocanvasitem.html#goo-canvas-item-rotate"><code class="function">goo_canvas_item_rotate()</code></a>.
</p>
<p>
<a class="link" href="GooCanvasPath.html" title="GooCanvasPath"><span class="type">GooCanvasPath</span></a> uses the same path specification strings as the Scalable
Vector Graphics (SVG) path element. For details see the
<a class="ulink" href="http://www.w3.org/Graphics/SVG/" target="_top">SVG specification</a>.
</p>
<p>
To create a <a class="link" href="GooCanvasPath.html" title="GooCanvasPath"><span class="type">GooCanvasPath</span></a> use <a class="link" href="GooCanvasPath.html#goo-canvas-path-new"><code class="function">goo_canvas_path_new()</code></a>.
</p>
<p>
To get or set the properties of an existing <a class="link" href="GooCanvasPath.html" title="GooCanvasPath"><span class="type">GooCanvasPath</span></a>, use
<a
href="/usr/share/gtk-doc/html/gobject/gobject-The-Base-Object-Type.html#g-object-get"

Here's an example showing how to create a red line from (20,20) to (40,40):
</p>
<p>
</p>
<div class="informalexample"><pre class="programlisting">
GooCanvasItem *path = goo_canvas_path_new (mygroup,
"M 20 20 L 40 40",
"stroke-color", "red",
NULL);
</pre></div>
<p>
</p>
<p>
This example creates a cubic bezier curve from (20,100) to (100,100) with
the control points at (20,50) and (100,50):
</p>
<p>
</p>
<div class="informalexample"><pre class="programlisting">
GooCanvasItem *path = goo_canvas_path_new (mygroup,
"M20,100 C20,50 100,50 100,100",
"stroke-color", "blue",
NULL);
</pre></div>
<p>
</p>
<p>
This example uses an elliptical arc to create a filled circle with one
quarter missing:
</p>
<p>
</p>
<div class="informalexample"><pre class="programlisting">
GooCanvasItem *path = goo_canvas_path_new (mygroup,
"M200,500 h-150 a150,150 0 1,0 150,-150 z",
