一、Demo截图效果

 

 

二、核心代码

        public void OnPropertyChanged(Object sender, PropertyChangedEventArgs args)
        {
            //Rect tmp = _layoutTransform.TransformBounds(((Rect)_content));
            if (null == _content)
            {
                return;
            }

            _content.RenderTransform = _layoutTransform;
            CompositeTransform tmp = (CompositeTransform) _layoutTransform;
            double radian = tmp.Rotation * Math.PI / 180;
            double d = (_content.Width) * (System.Math.Sin(radian) + System.Math.Cos(radian));
            double margin = Math.Abs((d  - _content.Width)/2);
            _content.Margin = new Thickness(margin);
        }
