[Insight-users] error when reading a vtk image file

[Luis Ibanez]

Hi qf1234546


Please post to the list the first 10 lines of
your .vtk file "sphere.vtk".


It is very likely that the content of this file
is not an actual vtkImageData.


BTW: In ITK you don't need to specify the itk::VTKImageIO object.
      The IO factory will do that for you. It is enough to
      provide a filename with extension .vtk, that contains
      an structured dataset.


You may want to read the ITK Software Guide


       http://www.itk.org/ItkSoftwareGuide.pdf


in particular the chapter on

       "Reading and Writing Images"



   Regards,




       Luis
