<a name="GooCanvasEllipse.description"></a><h2>Description</h2>
<p>
GooCanvasEllipse represents an ellipse item.
</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="GooCanvasItem.html" title="GooCanvasItem"><span class="type">GooCanvasItem</span></a> interface, so you can use the
<a class="link" href="GooCanvasItem.html" title="GooCanvasItem"><span class="type">GooCanvasItem</span></a> functions such as <a class="link" href="GooCanvasItem.html#goo-canvas-item-raise" title="goo_canvas_item_raise ()"><code class="function">goo_canvas_item_raise()</code></a> and
<a class="link" href="GooCanvasItem.html#goo-canvas-item-rotate" title="goo_canvas_item_rotate ()"><code class="function">goo_canvas_item_rotate()</code></a>.
</p>
<p>
To create a <a class="link" href="GooCanvasEllipse.html" title="GooCanvasEllipse"><span class="type">GooCanvasEllipse</span></a> use <a class="link" href="GooCanvasEllipse.html#goo-canvas-ellipse-new" title="goo_canvas_ellipse_new ()"><code class="function">goo_canvas_ellipse_new()</code></a>.
</p>
<p>
To get or set the properties of an existing <a class="link" href="GooCanvasEllipse.html" title="GooCanvasEllipse"><span class="type">GooCanvasEllipse</span></a>, use
<code class="function">g_object_get()</code> and <code class="function">g_object_set()</code>.
</p>
<p>
The ellipse can be specified either with the "center-x", "center-y",
"radius-x" and "radius-y" properties, or with the "x", "y", "width" and
"height" properties.

Here's an example showing how to create an ellipse centered at (100.0,
100.0), with a horizontal radius of 50.0 and a vertical radius of 30.0.
It is drawn with a red outline with a width of 5.0 and filled with blue:
