If the output image does not have the canonical IPW line (top to bottom) and sample (left to right) order, then it will be given an orientation ("or") header describing the non-standard ordering.

Geodetic ("geo") headers, window ("win") headers, and orientation ("or") headers will be modified if they are present.
