Yes, it appears to use some typedefs such as OffsetType specific to itk::MatrixOffsetTransformBase. Sadly, itk::TranslationTransform etc aren't derived from itk::MatrixOffsetTransformBase.<br><br>Try to add the line <br>
<br> typedef OutputVectorType OffsetType; <br><br>to itk::TranslationTransform and see if it works for you. If so, please send us the patch.<br><br>thanks<br><br><div class="gmail_quote">On Mon, Nov 9, 2009 at 1:23 PM, Lodron, Gerald <span dir="ltr"><<a href="mailto:Gerald.Lodron@joanneum.at">Gerald.Lodron@joanneum.at</a>></span> wrote:<br>

I am not sure if i understand this CenteredTransformInitializer class, can anyone explain me why itk::CenteredTransformInitializer does work for itk::AffineTransform but not for itk::TranslationTransform or itk::ScaleTransform?<br>
<br>
Maybe it is a bug?<br>

<br>
</div><div><div></div><div class="h5">Hi Gerald,<br>
<br>
Please post to the mailing list the compilation error that<br>
you get with this code.<br>
<br>
It will make a lot easier for us to advise you if we can<br>
see the error message.<br>
<br>
<br>
Also,<br>
please note that the following construction is incorrect:<br>
<br>
RegistrationType * m_Registration = RegistrationType::New();<br>
<br>
It should be:<br>
<br>
RegistrationType::Pointer m_Registration = RegistrationType::New();<br>
<br>
<br>
<br>
along the same lines, the statement:<br>
<br>
TransformType* m_Transformation =<br>
itk::AffineTransform<double, VImageDimension>::New();<br>
<br>
should be<br>
<br>
TransformType::Pointer m_Transformation =<br>
itk::AffineTransform<double, VImageDimension>::New();<br>
<br>
<br>
If you don't assign a newly created ITK object to a SmartPointer,<br>
the object will be destroyed by the next line in the code.<br>
<br>
If you are getting run-time errors, this misuse of the New() method<br>
may explain what is happening with your program at run-time.<br>
Introducing a proper use of SmartPointers may fix the problem.<br>
<br>
