IUIAnimationTransitionLibrary2::CreateLinearVectorTransitionFromSpeed method

Creates a linear-speed vector transition in the specified dimension.

Syntax


HRESULT CreateLinearVectorTransitionFromSpeed(
  [in]        DOUBLE                  speed,
  [in]  const DOUBLE                  *finalValue,
  [in]        UINT                    cDimension,
  [out]       IUIAnimationTransition2 **transition
);

Parameters

speed [in]

The absolute value of the velocity in units/second.

finalValue [in]

A vector (of size cDimension) that contains the final values of the animation variable at the end of the transition.

cDimension [in]

The number of dimensions to apply the transition. This parameter specifies the number of values listed in finalValue.

transition [out]

The new linear-speed transition.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See Windows Animation Error Codes for a list of error codes.

Remarks

During a linear-speed transition, the value of the animation variable changes at a specified rate. The duration of the transition is determined by the difference between the initial value and the specified final value.

The following figure shows the change in value over time of an animation variable during a linear-speed transition.
