Changes the value of the ScaleX property of a 3D scale transform. The ScaleX property specifies the scale factor along the x-axis.

Syntax

HRESULT SetScaleX(
  [in] float scaleX
);

Parameters

[in] scaleX

Type: float

The new x-axis scale factor.

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 scaleX parameter is NaN, positive infinity, or negative infinity.

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