C#.NET code snippet to flip annotations

      private void FlipImageAndAnnotations(bool horizontal, AnnContainer container, RasterImageViewer viewer)

      {

         // 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;

         foreach(AnnObject obj in container.Objects)

            obj.Scale(sx, sy, origin);

      }
