Hi,

finally I havetoreally face the issue of using real-world coordinates
for my piddles. So far, I've ignored rotations, which I no longer can
do. I guess thereare already a couple of implementations of at least
some of the features I need, so before Ireinvent the wheelI wanted toask
if you could point me to some solution.

Basically, I have data in cuboids in space with arbitrary rotation,
translation and pixel scaling. Now I would like toe.g. extract data from
the same spatial volume or add them together, etc. They may have extra
dimensions as well, some without equally spacing, some with non-numeric
coordinates.

I guess PDL::Transform is good for that.

How do you effectively store and attach/receive the information? I guess
as translation/rotation/scaling vectors in the header and some methods
to translate the slicing? How to translate this to an arbitrary number
of dimensions?
