IUIAnimationTransitionLibrary2::CreateLinearTransitionFromSpeed method

Creates a linear-speed scalar transition.

Syntax

HRESULT CreateLinearTransitionFromSpeed(
  [in]  DOUBLE                 speed,
  [in]  DOUBLE                 finalValue,
  [out] IUIAnimationTransition **transition
);

Parameters

speed [in]

The absolute value of the velocity in units/second.

finalValue [in]

The value of the animation variable at the end of the transition.

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.
