The second parameter is the amount to which the supplied paths will be offset. Negative delta values shrink polygons and positive delta expand them.<br><br> This method can be called multiple times, offsetting the same paths by different amounts (ie using different deltas).<br><br> <img src="../../../../../../Images/offset1.png" alt="" width="310" height="314" border="0" align="right">
