Namespace:  System.Windows.Media
Assembly:  System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.

public double CenterX { get; set; }
<RotateTransform CenterX="double"/>

Property Value

Type: System.Double
The x-coordinate of the center of rotation. The default is 0.

Dependency property identifier field: CenterXProperty

When you use a RotateTransform, realize that the transformation rotates the coordinate system for a particular object about the point (0, 0). Therefore, depending on the position of the object, it might not rotate in place (around its center). For example, if an object is positioned 200 units from 0 along the x-axis, a rotation of 30 degrees can swing the object 30 degrees along a circle that has a radius of 200, which is drawn around the origin. To rotate an object in place, set the CenterX and CenterY of the RotateTransform to the center of the object to rotate.

The local 0,0 for an object can be offset on a Canvas using Canvas.Left and Canvas.Top, but this does not count as a transform; the object retains its own local 0,0 in this case for transform purposes.
