/**
 * A simple container class to aggregate an image, a set of
 * thumbnail (preview) images, and an object representing metadata
 * associated with the image.
 *
 * <p> The image data may take the form of either a
 * {@code RenderedImage}, or a {@code Raster}.  Reader
 * methods that return an {@code IIOImage} will always return a
 * {@code BufferedImage} using the {@code RenderedImage}
 * reference.  Writer methods that accept an {@code IIOImage}
 * will always accept a {@code RenderedImage}, and may optionally
 * accept a {@code Raster}.
 *
 * <p> Exactly one of {@code getRenderedImage} and
 * {@code getRaster} will return a non-{@code null} value.
 * Subclasses are responsible for ensuring this behavior.
