[Insight-users] ITK-TIF-support: 3D supported but float not?

[Luis Ibanez]

Hi Lynx,

The ITK implementation of TIFF only supports

   * signed char
   * unsigned char
   * signed short
   * unsigned short

(a grep for "m_ComponentType" in the itkTIFFImageIO
 will reveal as much).


It is possible, however, that the underlying "tiff" libraries
support "float" as a pixel type.

But that functionality is not exposed at this point.

As Dan suggested, you may want to use the MetaImage
file format instead of TIFF.


     Regards,


          Luis
