Gets or sets the x-coordinate of the rotation center point.

XMLNS for XAML: Not mapped to an xmlns.
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 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.
