[Insight-users] changing image orientation

[Luis Ibanez]

Hi Shoosh,

   This is not the correct way of modifying the orientation of an image.


In general you should never attempt to change the content of an image
that is the output of a filter or a reader.

The correct way of changin the orientation of an image is to use the


     itkChangeInformationFilter

http://www.itk.org/Insight/Doxygen/html/classitk_1_1ChangeInformationImageFilter.html

Call on it

    ChangeDirectionOn()

and

     SetOutputDirection( newdirection)



    Regards,



         Luis
