一、Demo效果

 

 

 

二、核心代碼

 1         public void OnPropertyChanged(Object sender, PropertyChangedEventArgs args) 2         { 3             //Rect tmp = _layoutTransform.TransformBounds(((Rect)_content)); 4             if (null == _content) 5             { 6                 return; 7             } 8  9             _content.RenderTransform = _layoutTransform;10             CompositeTransform tmp = (CompositeTransform) _layoutTransform;11             double radian = tmp.Rotation * Math.PI / 180;12             double d = (_content.Width) * (System.Math.Sin(radian) + System.Math.Cos(radian));13             double margin = Math.Abs((d  - _content.Width)/2);14             _content.Margin = new Thickness(margin);15         }
