<DIV>Thanks jJulien it works,</DIV>
<DIV> </DIV>
<DIV>maybe if I can another question about the implementation of static methods in ITK...</DIV>
<DIV><BR>myFunction is a static function and it is define in a .h and implemented in a .txx <BR>so if I put everything in my .h like you said it works:</DIV>
<DIV><BR>typedef typename ImageType::Pointer InputImagePointer; <BR>static InputImagePointer::Pointer myFunction(...)<BR> {<BR>....<BR>}<BR>or if I don't want to use the typedef<BR>static typename TImage::Pointer myFunction(...)<BR> {<BR>....<BR>}<BR>and you guess that My Object is templated using TImage ...</DIV>
<DIV> </DIV>
<DIV>BUT, I don't know how to implement it in my .txx and just define the header function in my .h as we do usually (it never compile ....)</DIV>
<DIV><BR>.h<BR> typedef typename ImageType::Pointer InputImagePointer; <BR> static InputImagePointer::Pointer myFunction(...);<BR>.txx<BR>static InputImagePointer::Pointer myFunction(...)<BR>{</DIV>
<DIV>}<BR><BR>Thanks julien for help,</DIV>
