[Insight-users] double to float problem

[Luis Ibanez]

Hi Yasser,


You could get around this problem, without having to upgrade ITK,
by changing the declarations of the Spacing callbacks in the files:


                Insight/
                  Code/
                    BasicFilters/
                      itkVTKImageExport.h
                      itkVTKImageExport.txx
                      itkVTKImageExportBase.cxx
                      itkVTKImageExportBase.h
                      itkVTKImageImport.h
                      itkVTKImageImport.txx


You would have to change them from "float" to "double" in order
to match the new VTK types.


----

However, ITK 1.6 is quite old.


I will strongly encourage you to upgrade to ITK 2.4.1


Please let us know if you encounter any other problems.





   Thanks


      Luis
