SPAM: [Insight-users] read raw images

[Julien Jomier]

Hi Camille,

It seems that you are only setting the RawImageIO for the writer and not 
the reader. Also you need to provide more information, i.e size of the 
image otherwise ITK won't be able to guess it.

You can take a look at the 
Insight\Testing\Code\IO\itkRawImageIOTestX.cxx file for more information.

Hope that helps,

Julien
