Ellipses are commonly used shapes. Just include the following header.

#include <agg_ellipse.h>

Then you can specify a ellipse using x, y, rx, and ry. There are additional parameters which you can customize.

agg::ellipse eliipse (100, 100, 50, 80);

Note that it is not necessary to use agg::conv_curve to convert path commands.

Example

tutorial_shape_1.cpp draws a very simple ellipse.
