+/**
+ * This interface is designed to be an optional additional API supported by
+ * some implementations of {@link java.awt.Image} to allow them to provide
+ * alternate images for various rendering resolutions. The various
+ * {@code Graphics.drawImage(...)} variant methods will consult the methods
+ * of this interface if it is implemented on the argument {@code Image} object
+ * in order to choose the best representation to use for each rendering operation.
+ * <p>
+ * The {@code MultiResolutionImage} interface should be implemented by any
+ * subclass of {@code java.awt.Image} whose instances are intended to provide
+ * image resolution variants according to the given image width and height.
+ * For convenience, toolkit images obtained from
+ * {@code Toolkit.getImage(String name)} and {@code Toolkit.getImage(URL url)}
+ * will implement this interface on platforms that support naming conventions
+ * for resolution variants of stored image media and the
+ * {@code AbstractMultiResolutionImage} and {@code BaseMultiResolutionImage}
+ * classes are provided to facilitate easy construction of custom multi-resolution
+ * images from a list of related images.
