[Insight-developers] ITK-VTK image and problems with includes in visual c++ express 2008

[Luis Ibanez]

Hi Matthieu,

Use the example:

     Insight/Examples/IO/
        ImageReadImageSeriesWrite.cxx

You will find it explained in the ITK Software Guide


   http://www.itk.org/ItkSoftwareGuide.pdf



   Regards,


      Luis

     to the maintenance and extension of the toolkit.  Thanks.
