[Insight-developers] Could not create IO object for file cthead1.png

[Gaëtan Lehmann]

I forgot to say that setting the ImageIO by hand works:

1> import itk

2> reader = itk.ImageFileReader.IUC3.New(FileName="/home/glehmann/src/ 
ITK/Wrapping/WrapITK/images/cthead1.png")

3> reader()

/home/glehmann/src/ITK/build/lib/ITKCommonBasePython.py in

    2452         import itk

   Tried to create one of the following:
   You probably failed to set a file suffix, or
     set the suffix to an unsupported type.


4> pngio = itk.PNGImageIO.New()

5> reader.SetImageIO(pngio)

6> reader()
