[Insight-users] Problems trying to update ImageFileReader.

[Luis Ibanez]

Hi Fran,


I don't see the *image filename* in the path that you are providing:

reader->SetFileName(
"D:\personal\fvazquez\itk180\proyectos\ITKHaloCount\HaloCountv019-1v6\Debug");


It seems that you are simply passing a *directory* name, and not
a *filename*.


I would have expected the path to have at the end something like:


                         "myImage.jpg"



Maybe you have a problem in the file dialog that you are using for
selecting the filename.



    Regards,


       Luis
