Plugin IO mechanisms
ITK provides a very flexible ImageIO mechanism supporting factories. This allows for a single reader class and a single writer class that can input/output a variety of file formats. When ImageFileReader begins to read a file, it queries the ObjectFactory system for any factory that can supply an ImageIOBase. This subset of factories is queried in turn to locate a factory that can understand the format of the requested file.
New image file formats can be added to ITK by deriving a class from ImageIOBase that will support reading/writing that file format. The file format can be added to the factory mechanism by creating a subclass of ObjectFactoryBase for the specific for this ImageIO class.
