[Insight-users] itkVTKImageToImageFilter

[Yan Pingkun]

Hi Luis,

Thanks for your instruction. I put a try/catch there and it told me
"Input scalar type is unsigned char but should be float".
Then I changed the image data type and it works now!

Regards,
Pingkun

Hi Yan,

You are using incompatible versions
of Insight and InsightApplications.

Please syncronize your checkouts.

The itkVTKImageToImageFilter in


      InsightApplications/Auxiliary/vtk


depends on the itkVTKImageImport in


      Insight/Code/BasicFilters


Both files should correspond to the
same release of ITK or to the same
CVS date.


About the crash... did you tried adding
a try/catch block around the Update()
invokation  ?



    Regards,



       Luis
