[Insight-users] Error: itkVTKImageImport

[Luis Ibanez]

Hi Firat,


Well,
the error message is giving you a strong hint:


    > Description: itk::ERROR: VTKImageImport(0x948c9e8):
    > Input scalar type is double
    > but should be float


You probably instantiated the itkVTKImageImport filter using a "float"
pixel type, and at run-time you are passing to it an image whose pixel
type is "double".


So,
you have three choices:


   A) Instantiate the itkVTKImageImport filter with an image
      of pixel type "double"

or

   B) Convert the input image from double to float
      (e.g. by using a casting filter)

or

   C) Use the classes described in the following
      Insight Journal paper:

    Regards,


       Luis
