[Insight-developers] ImageAdaptors, ImageBase, extracting enum during derivation

[Miller, James V (CRD)]

Luis,

I am still working on revamping ImageBase.  I have hit a problem with subclassing ImageAdaptor from
ImageBase. ImageAdaptor is templated over image type and accessor type.  But in specifying its
derivation from ImageBase, we need to tell ImageBase the dimension of the image.  So what I like to
write is code like....

template <class TImage, class TAccessor >
class ITK_EXPORT ImageAdaptor : public ImageBase<TImage::ImageDimension>
{
public:
...

But the compilers are tripping over over the "public ImageBase<TImage::ImageDimension>" clause, and
incorrectly translating this to "public ImageBase<0>".

Do you know of a way to specify the derivation so ImageBase is templated over the dimension of the
image (which is the template parameter to ImageAdaptor)?

The only path I see so far is add a template parameter to the ImageAdaptor which the dimension of the
image it is adapting.
