/**
 * The service provider interface (SPI) for

 * provider interfaces, see the class comment for the
 * {@code IIORegistry} class.
 *
 * <p> This interface allows arbitrary objects to be "wrapped" by
 * instances of {@code ImageOutputStream}.  For example, a
 * particular {@code ImageOutputStreamSpi} might allow a generic
 * {@code OutputStream} to be used as a destination; another
 * might output to a {@code File} or to a device such as a serial
 * port.
 *
 * <p> By treating the creation of {@code ImageOutputStream}s as
 * a pluggable service, it becomes possible to handle future output
 * destinations without changing the API.  Also, high-performance
 * implementations of {@code ImageOutputStream} (for example,
 * native implementations for a particular platform) can be installed
 * and used transparently by applications.
