[Insight-users] NthElement Image output

[jmerkow]

Thank You!  I didn't know this class existed. 
I take it that this adapter is used to perform vector operations at the
image level?
My end goal is to perform a dot product of these gradients with a surface
normal.  Is this adapter usually used in something like this fashion?

i.e. in combination with something like this:
