35 * @interface IVisualElementAnimationTimingFunction
36 * @brief This interface implements the timing function for the VisualElementAnimation defined in the Tizen::Ui::Animations namespace.
40 * The %IVisualElementAnimationTimingFunction interface is the timing function interface for the pacing of an animation.
41 * The class that defines the pacing of an animation as a timing curve implements this interface,
42 * and the instance created with that class is registered with an animation,
43 * using the VisualElementAnimation::SetTimingFunction() method or the AnimationTransaction::SetVisualElementAnimationTimingFunction() method.
44 * When tick of the animation occurs, a method of that instance is invoked.
46 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/ui/timing_function.htm">Timing Function</a>.
49 class _OSP_EXPORT_ IVisualElementAnimationTimingFunction
54 * This is the default constructor for this class.
58 IVisualElementAnimationTimingFunction(void);
62 * This is the destructor for this class.
66 virtual ~IVisualElementAnimationTimingFunction(void);
70 * Calculates the progress(pace) of an animation regarding the time elapsed.
74 * @return The progress(pace) value calculated by the time progress value and the timing function type @n
75 * @c 0 and @c 1 are the start and end values of an animation, respectively.
76 * @param[in] timeProgress The time progress value @n
77 * This must be in the range @c 0.0 to @c 1.0.
