IUIAnimationTransitionLibrary2::CreateLinearTransitionFromSpeed method (uianimation.h)

  • Article

Creates a linear-speed scalar transition.

Syntax

HRESULT CreateLinearTransitionFromSpeed(
  [in]  DOUBLE                  speed,
  [in]  DOUBLE                  finalValue,
  [out] IUIAnimationTransition2 **transition
);

Parameters

[in] speed

The absolute value of the velocity in units/second.

[in] finalValue

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

[out] transition

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.
