[Insight-users] Casting Adaptor?

[Bradley Lowekamp]

Hello Luis,

	Thank you for pointing me towards that example. I forgot that when I  
need this adaptation I usually code up my own adaptor; it just seemed  
like it should be in ITK. If this is "typical use" then why is a  
templated CastPixellAccessor such as the following not part of ITK?

template <class TInternalType, class TExternalType > class ITK_EXPORT  
CastPixelAccessor
{

   static inline void Set(InternalType & output, const ExternalType &  
input)
   {output = static_cast<InternalType>( input );}

   static inline ExternalType Get( const InternalType & input )
   {return static_cast<ExternalType>( input ); }
};

Brad
