[Insight-users] file reader

[Gwenaël Guillard]

Hi,

I try to use a file reader. I wrote, as in the GaussianFilter example

       VolumeReaderType::Pointer Reader = VolumeReaderType::New();
       itk::MetaImageIO::Pointer metaImageIO = itk::MetaImageIO::New();
       Reader->SetImageIO( metaImageIO );
       Reader->SetFileName( filename );

But when I want to get
Reader->GetOutput()->GetLargestPossibleRegion()->GetSize(), for example,
it gives me 0,0,0, which is not
the dimensions of my data. These data are .rwa and I use a mhd file. I
use the mhd file with the GaussianFilter example and it was
ok.

Thank you,

Gwenael
