If an embedded object's source program (source program: The program used to create a linked object or embedded object. To edit the object, you must have the source program installed on your computer.) is unavailable, you can convert it to a Microsoft Office drawing object (drawing object: Any graphic you draw or insert, which can be changed and enhanced. Drawing objects include AutoShapes, curves, lines, and WordArt.) to edit. After you convert an embedded object (embedded object: Information (object) contained in a source file and inserted into a destination file. Once embedded, the object becomes part of the destination file. Changes you make to the embedded object are reflected in the destination file.) to an Office drawing object, it is no longer connected to the original program.
Note You cannot ungroup a bitmap.
