Extent iterator.
The extent iterator is implicitely convertible to Point, and is therefore ideally suited for Get/Set methods which take a point as an argument.
ImageHandle ih = get_some_image(); for(ExtentIterator it(ih.GetExtent());!it.AtEnd();++it) { Real r = ih.GetReal(it); // do something with value }
