exist for use with the forthcoming Java Advanced Imaging (JAI) API (javax.jai.*) and are
not of interest to programs using Java 2D. Nevertheless, BufferedImage implements this
inter face, so that Java 2D BufferedImage objects can interoperate with future JAI Rendered-
Image objects. BufferedImage objects contain only a single tile and provide trivial imple-
mentations of all the tile-related methods. setData() is the only method of interest to Java
2D programs.
