I used the rasterImageViewer.Image.RotateViewPerspective to rotate the image in which rasterImageViewer is attached to the AnnAutomationmanger.
automation = new AnnAutomation(annAutomationManager, rasterImageViewer);

I found that the annotations on the rasterImagerViewer does not rotate when the image is rotate. Is it expected?

If you want to rotate the annotation objects with the image, after rotating the image, use the following code to rotate all the annotation objects:
+----+
PointF origin = new PointF(viewer.Image.ImageWidth / 2,
viewer.Image.ImageHeight / 2);

viewer.Image.RotateViewPerspective(angle);

AnnPoint annOrigin = new AnnPoint(origin, AnnUnit.Pixel);

foreach(AnnObject obj in container.Objects)
{
obj.Rotate(angle, annOrigin);
}
+----+

Thanks,
