Ok, then I believe that:

- itk::ImageSeriesWriter should add ITK_Origin, ITK_Spacing and
ITK_NumberOfDimensions to all MetaDataDictionary of the Array if it is
set (because if a 3D image is used to produce a 2D image set, the 3rd
value of the origin is lost by ImageSeriesWriter, then on line "1320
ipp.SetValue( origin[2], 2);" the value set is always 0

and/or

- itk::GDCMImageIO (GDCM2 only) should replace m_Origin values from
the values read from IPP if this was set by the user.


Thanks,
 Daniele
