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

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

Syntax

HRESULT SetCenterX(
  [in] float centerX
);

Parameters

[in] centerX

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

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

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