[Insight-users] need help with my Code

[Luis Ibanez]

Hi Nadia,

As far as I know, TIFF can't store 3D images.

I don't quite understand how the code can
generate a 3D TIFF image for you...

Are you talking about a multi-frame TIFF,... maybe ?


To figure out what ImageIO was used you can do the
following (of course, first remove the SetImageIO),

then,

after the call to

               writer->Update()

add the following call

    writer->GetImageIO->Print( std::cout );

The text that you will get in the console should
include the class name of he ImageIO that was
selected during the search of ImageIOFactories.


Please post that output to the list,


    Thanks


       Luis
