Solving Issue rotating device and view should rotate with center

I have an Issue to be solved. I have already a sample app to demonstrate the Issue. - My App has 3 points and a red cross in the center. Blue, Green, Red. - When starting the App the green point is in the center of the app. The Red cross is exactly over the green point. - The View can be scaled and translated (moving with touch and scaling with gesture) Now my Issue: The Red Cross indicating the center should be still the same center after rotating the device. My sample App shows the red cross and the green point in the center at start ([login to view URL] attached). After rotating the device, the green point is not anymore in the center. ([login to view URL] attached) -> If the red cross is over the green point, then after rotating the green point should be still in the center with the red cross. -> This should also work fine when scaled in or out. -> This should also work after translated the view to one of the other points (red, blue). Mean if red is centered it should be centered after rotating in any position of the device
