[Insight-users] performance of image iterators and pixel buffer storage

[David Fuentes]

When using an iterator with an ITK image, it is hard to determine whether or
not the iterator is iterating over a continuous array of memory.
How is the pixel buffer stored in a 2D/3D ITK image?

row major storage?
column major storage?
Is the pixel buffer for a 3D image is stored in a continuous array 
of memory?

which value for

   SetDirection()

should be used to give the best performance?





thank you,
