[Insight-developers] Can SpatialObject be a subclass of Image Base?

[Miller, James V (Research)]

I can (almost) live with that.  It seemed strange for a SpatialObject to a
subclass of ImageBase.  However, I don't think that ImageBase should have
all of the API of a SpatialObject.  Perhaps there should be a common
superclass that the shared code could be moved into. No idea what to call it
(ImageAndSpatialObjectBase?)

Hi,

We are making changes to SpatialObjects - including a 
SpatialObjectSource, etc.   Also, MITK is being integrated with ITK via 
spatialObjects, so the tree hierarchy of SpatialObjects is being 
extended.   I'd hesitate to make other changes simultaneously.

SpatialObjects contain images possibly.  That seems very circular. 
Perhaps image should derive from spatialObject, but the other way around 
seems very odd.

Thanks,
Stephen
