[Insight-users] ImageToImageFilter for the watershed transformation

[Cameron Burnett]

Hi Edgar,

I don't think you can actually use the ImageToImageFilter like that. I think its just a function that other filters use. For that reason, the New() function just returns and object pointer and not a  smart pointer. If you want to convert your image types you should be able to use a casting filter of some sort. Maybe like the one you already have included? I'm not exactly sure because I've only been using ITK for about a month.

Hope that helps a bit.

Cameron.
