[Insight-users] Insight-users Digest, Vol 74, Issue 36

[Luis Ibanez]

Hi Sere,


Please make sure that you call

                  maskReader->Update()


before you call

spatialObjectMask->SetImage( maskReader->GetOutput() );


Otherwise, you will not have an image
set inside the MaskSpatialObject.


      Luis
