Hi guys,<br><br>I am not sure how to use itkTypeMacro.<br><br>Should I always use it like:<br><br>itkTypeMacro(thisClass,superclass)<br><br>If my class is derived from itkSingleValuedCostFunction, <br><br>class ITK_EXPORT MyClass : public SingleValuedCostFunction<br>

{...}<br><br>can I define something like <br><br>itkTypeMacro(MyClass, ImageToImageFilter); ?<br><br>Also what does ‘<span style="visibility: visible;" id="main"><span style="visibility: visible;" id="search"><em>itkTypeMacro</em> allows you to <em>use</em> 
run time type information</span></span>’ mean?<br><br><br><br>Thanks,<br>Aaron<br>
