Detailed Description

template<class T>
class CVD::ImageCreationIterator< T >

An input iterator which just returns N copies of the same value over and over again.

This can be used for construction of containers of images. For intstance the code:

    vector<Image<float> > foo(3, ImageRef(10,10));

All elements of foo point to the same 10x10 image, which is probably not the desired behaviour. The desired behaviour can be obtained with the ImageCreationIterator:

    ImageCreationIterator<ImageRef> begin(10,10), end(3);
    vector<Image<float> > foo(begin, end);

In this case, foo contains 3 distinct images.
