[Insight-users] Urgent question about Examples/Filtering/FFTImageFilterFourierDomainFiltering.cxx.

[Luis Ibanez]

Hi Jim,

In order to save images with pixel type float or double
you should consider using:


      a) MetaImage   .mhd
      b) VTK         .vtk
      c) Nrrd        .nrrd
      d) Nifti       .hdr


Please see the FAQ in the Wiki for a list of the
file formats supported in ITK:

Regards,


     Luis
