[Insight-developers] Re: Meta byte swapping problems for doubles

[Stephen R. Aylward]

Thanks for the help - you're right about the 64bit (of course).   One of 
the major flaws in ITK is that much of it is based on native types 
(assumes a char is 8 bits, etc).   I will try to fix both at the same time.

Thanks,
Stephen
