IDCompositionRotateTransform3D::SetAxisY(float) method (dcomp.h)

Article
02/22/2024

Changes the value of the AxisY property of a 3D rotation transform. The AxisY property specifies the y-coordinate for the axis vector of rotation. The default value is zero.

Syntax

HRESULT SetAxisY(
  [in] float axisY
);

Parameters

[in] axisY

Type: float

The new y-coordinate for the axis vector of rotation.

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

When setting the axis to a non-default value, you should always set all three axis properties (AxisX, AxisY, and AxisZ).

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

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