[Insight-users] issue with metaImageIO

[Luis Ibanez]

Hi Ken,

The description of your problem seems to be incomplete.

Could you please start by telling us what
you are actually trying to do ?


     Thanks


        Luis


----

BTW: Please note that you don't need to connect a MetaImageIO
      to the file writer. The ImageIO factories take care of
      finding the proper ImageIO class based on the filename
      that you pass to the writer.

Also, please about the use of the expression

          "using namespace std"

it defeats the purpose of using namespaces.
