[Insight-users] Help on using itk::MetaImageIO to write a *.mhd file

[Luis Ibanez]

Hi Jinzhong,

You could manipulate the image information:

        * Spacing
        * Origin
        * Orientation


with the filter:

http://public.kitware.com/Insight/Doxygen/html/classitk_1_1ChangeInformationImageFilter.html


before you send the image to the writer.


This is something that you should do very carefully
if you are dealing with real patient data.


    Regards,


          Luis
