RotateTransform을 사용하여 중심에서 DrawingBrush 회전

회전하려는 나침반의 UserControl이 있습니다. 나는 그것을 중심에서 회전하려고 노력하고 있으며 Google은 RenderTransformOrigin="0.5,0.5"이것을 달성하기 위해 사용 하는 것에 대한 많은 참조를 찾고 있습니다 . 그러나 이것은 어떤 이유로 작동하지 않습니다. 모서리를 원점으로하는 UserControl 만 회전합니다.

내가 설정 CenterX="150"하고 CenterY="150"UserControl 내부에 있으면 작동합니다. 그러나 그런 다음 주 창에서 UserControl의 높이와 너비를 300으로 설정해야합니다.

UserControl을 호출 할 때 설정 한 높이 및 너비 설정에 관계없이 UserControl을 중심점에서 회전하려면 어떻게해야합니까? 또한 호출 할 때보다는 UserControl 내부에 RenderTransformOrigin을 설정하는 것을 선호합니다.
