[Insight-developers] concept checking in blox classes

[Amy Squillacote]

Dear Robert and George,

As you probably know, we recently started adding concept checking 
into ITK.  Our plan of action was described in this recent e-mail to 
the developers list:
http://www.itk.org/mailman/private/insight-developers/2006-February/007652.html.

As you can see from this plan, we will need some help from the 
authors of the filters in order to determine the specific 
restrictions on the types over which the filters are intended to be 
instantiated.

As part of this process, we just found in the class:

itkBloxBoundaryProfileImageToBloxCoreAtomImageFilter

that despite being templated over the image type and the dimension, 
it can only be instantiated when the dimension and the image 
dimension are both equal to 3.  We are wondering if this is the 
intended behavior or if this is a bug.  If this is the intended 
behavior, we are wondering why the second template parameter is needed.

Please let us know what you think.

- Amy
