Changes the value of the ScaleY property of a 2D scale transform. The ScaleY property specifies the scale factor along the y-axis.

Syntax

HRESULT SetScaleY(
  [in] float scaleY
);

Parameters

[in] scaleY

Type: float

The new y-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 scaleY parameter is NaN, positive infinity, or negative infinity.

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