[Insight-developers] Re: backward imcompatible changes in gaussian spatial object ?

[Julien Jomier]

Strange... it should work.
I just tested the itkSpatialObectToImageFilterTest with a writer and 
calling the Update() on the writer and it propagates to the filter as 
expected.

Is that only happening when using the wrapped version of the filter?
