IDCompositionRectangleClip::SetTopLeftRadiusX(float) method

Changes the value of the TopLeftRadiusX property of this clip. The TopLeftRadiusX property specifies the x radius of the ellipse that rounds the top-left corner of the clip.

Syntax


HRESULT SetTopLeftRadiusX(
  [infloat radius
);

Parameters

radius [in]

Type: float

The new value of the x radius. This parameter has a numerical limit of -2^21 to 2^21. The API accepts numbers outside of this range, but they are always clamped to this range.

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

This method fails if the radius parameter is NaN, positive infinity, or negative infinity.

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