<?php
$img = Yii::app()->image->create(new YiiImageBox(800, 600));
$drawer = $img->draw();
$drawer->onBeforeDrawPolygon = function (YiiImageDrawerEventOnDrawPolygon $event)
{
var_dump($event->color);
};
$drawer->line(new YiiImagePoint(3, 3), new YiiImagePoint(50, 50), new YiiImageColor('#00FF00'))
->ellipse(new YiiImagePoint(300, 300), new YiiImageBox(200, 400), new YiiImageColor('#FF0000'))
->polygon(array(

new YiiImagePoint(300, 400),
new YiiImagePoint(300, 410),
new YiiImagePoint(200, 430),
