An abstract superclass for encoding and writing images. This class
must be subclassed by classes that write out images in the context
of the Java Image I/O framework.
ImageWriter objects are normally instantiated by
the service provider class for the specific format. Service
provider classes are registered with the IIORegistry,
which uses them for format recognition and presentation of
available format readers and writers.
