[Insight-users] Other image file formats supported by ITK

[Luis Ibanez]

Hi Mark,

A larger description of the image file formats supported
by ITK is available at

     http://www . itk . org/HTML/Data . htm

and the FAQ entry

http://www . itk . org/cgi-bin/InsightFAQ/InsightFAQ?req=show&file=faq01 . 007 . htp

(for more entries on the FAQ you may want to check
http://www . itk . org/cgi-bin/InsightFAQ/  )


Hopefully you will find some of these file formats to be useful.


Regards,


    Luis
