[Cfun1]

I have a PathGeometry used with in an Image.Clip, that i want to apply a rotation to it before applied to the image is ther ea way to achieve that ?
i was expecting a Rotation property for PathFigure but it doesn't exist.

PathGeometry or PathFigures can be the Data for a Path object. And then the Path object has RotateTo()

I know but as described it can be the value of an Image.Clip also, in this case there is no Path object.
