Inheritance diagram for itk::ImageRegionReverseConstIterator< TImage >:
ImageRegionReverseConstIterator is a templated class to represent a multi-dimensional iterator. ImageRegionReverseConstIterator is templated over the dimension of the image and the data type of the image. ImageRegionReverseConstIterator is constrained to walk only within the specified region.
ImageRegionReverseConstIterator is a multi-dimensional iterator, requiring more information be specified before the iterator can be used than conventional iterators. Whereas the std::vector::iterator from the STL only needs to be passed a pointer to establish the iterator, the multi-dimensional image iterator needs a pointer, the size of the buffer, the size of the region, the start index of the buffer, and the start index of the region. To gain access to this information, ImageRegionReverseConstIterator holds a reference to the image over which it is traversing.
ImageRegionReverseConstIterator assumes a particular layout of the image data. The is arranged in a 1D array as if it were [][][][slice][row][col] with Index[0] = col, Index[1] = row, Index[2] = slice, etc.
operator++ provides a simple syntax for walking around a region of a multidimensional image. For a reverse iterator, operator++ moves backwards through the region. operator++ iterates across a row, constraining the movement to within a region of image. When the iterator reaches the boundary of the region along a row, the iterator automatically wraps to the previous row, starting at the last pixel in the row that is part of the region. This allows for simple processing loops of the form:
it = it.Begin();
for (; !it.IsAtEnd(); ++it)
{
*it += 100.0;
}

iterator's index. For a reverse iterator, this moves backwards through the region. This operator will constrain the iterator within the region (i.e. the iterator will automatically wrap from the start of the row of the region to the end of the previous row of the region) up until the iterator tries to moves before the first pixel of the region. Here, the iterator will be set to be one pixel before the start of the region.
