ImgPageIterator Class Reference
#include <image.h>
Class 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.
