mitk::IOUtil cannot save DiffusionImages, loading works
Closed, InvalidPublic
Actions

Description

I use the IOUtil in a test in DiffusionCore Module to load/save (diffusion-)images. With

RegisterDiffusionCoreObjectFactory();
mitk::Image::Pointer inputImage  = mitk::IOUtil::LoadImage(str_filename);

the corresponding image is loaded correctly, but at the end of the test, when I call

mitk::IOUtil::SaveImage( dwi_image_out, "/tmp/output.dwi" )

the IOUtil reponses with:

!2.989! WARNING: .dwi extension is unknown. Extension set to default:  /tmp/output.nrrd
[4.429] Diffusion-Image successfully initialized.
[4.440] Writing image: /tmp/output.nrrd

This should not happen, the factory is correctly registered.

Ok, the call to SaveImage( <DWI_IMAGE> ) is not correct, as it instantiates the FileWriter ( from MITK/Core ) and is hence not able to handle DWI images.

But it should work with SaveBaseData( <DWI_IMAGE> ), but the behaviour is the same, it exits with the statement:

".dwi extension is unknown."

The issue is meanwhile invalid, after re-factoring the Reader/Writer to a Service.
