  [infloat centerX
);

Parameters

centerX [in]

Type: float

The new x-coordinate of the center point.

Return value

Type: HRESULT

If the function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See DirectComposition Error Codes for a list of error codes.

Remarks

If the CenterX property was previously animated, this method removes the animation and sets the CenterX property to the specified static value.
