IDCompositionScaleTransform::SetCenterY(float) method (dcomp.h)

Changes the value of the CenterY property of a 2D scale transform. The CenterY property specifies the y-coordinate of the point about which scaling is performed.

Syntax

HRESULT SetCenterY(
  [in] float centerY
);

Parameters

[in] centerY

Type: float

The new y-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

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

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