         // calculate the origin
         AnnPoint origin = new AnnPoint(viewer.Image.ImageWidth / 2, viewer.Image.ImageHeight / 2, AnnUnit.Pixel);
 
         // flip the image
         viewer.Image.FlipViewPerspective(horizontal);
 
         // now flip each object around the origin.
         float sx = horizontal ? -1 : 1;
         float sy = horizontal ? 1 : -1;
