Theory

The theoretical background for all implementations is Dale Schumacher's article General Filtered Image Rescaling in Graphics Gems III, editor David Kirk, Academic Press, pages 8-16, 1994.

The Graphics Gems Repository can be found at http://www.acm.org/tog/GraphicsGems/. It also includes information on the books and how to order them. @author Marco Schmidt
