[Insight-users] Casting Adaptor?

[Luis Ibanez]

Hi Brad,


You are right in that such basic adaptor should be a standard class
in the toolkit. It is ironic that we have a family of less commonly
used adaptors and we missed the most obvious one:  Casting.

It is simply a shameful omission...


    We could easily add it at this point.

    Would you mind submitting a one page
    contribution to the Insight Journal   ?


It will simply require to attach to it the code that you already
wrote for the CastImageAdaptor.


    Thanks


       Luis
