+ *  which expose image or pixmap content on-screen.
+ * @Title:AtkImage
+ *
+ * #AtkImage should be implemented by #AtkObject subtypes on behalf of
+ * components which display image/pixmap information onscreen, and
+ * which provide information (other than just widget borders, etc.)
+ * via that image content.  For instance, icons, buttons with icons,
+ * toolbar elements, and image viewing panes typically should
+ * implement #AtkImage.
+ *
+ * #AtkImage primarily provides two types of information: coordinate
+ * information (useful for screen review mode of screenreaders, and
+ * for use by onscreen magnifiers), and descriptive information.  The
+ * descriptive information is provided for alternative, text-only
+ * presentation of the most significant information present in the
+ * image.
