+        #i30669#
+        Because most of the Writer object positions doesn't correspond to the
+        object positions in WW8, this method converts the positioning
+        attributes. For this conversion the corresponding layout information
+        is needed. If no layout information exists - e.g. no layout exists - no
+        conversion is performed.
+        No conversion is performed for as-character anchored objects. Whose
+        object positions are already treated special in method <WriteData(..)>.
+        Usage of method: Used by method <SetAnchoring(..)>, nothing else
+
+        @param _iorHoriOri
+        input/output parameter - containing the current horizontal position
+        attributes, which are converted by this method.

+        input/output parameter - containing the current vertical position
+        attributes, which are converted by this method.
+

+        input parameter - frame format of the anchored object
+
+        @return boolean, indicating, if a conversion has been performed.
