<p>This should be implemented by <a class="el" href="classAtk_1_1Object.html" title="The base object class for the Accessibility Toolkit API.">Atk::Object</a> 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.

<p><a class="el" href="classAtk_1_1Image.html" title="The ATK Interface implemented by components which expose image or pixmap content on-screen.">Atk::Image</a> primarily provides two types of information: coordinate information (useful for screen review mode of screenreaders, and for use by onscreen magnifiers), and descriptive information.
