Detailed Description

Iterates over a specified region of an image in optimal order.

It does not lock the region of the image or otherwise cause it to be present in CPU memory -- for that, use ImgLockPageIterator... Note that the regions returned are the tiles, stripes or pages that intersect the requested region -- they may encompass a larger area than you request, or even the entire image.
