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.

HRESULT SetCenterX(
  float centerX
);

Parameters

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.
