InertiaProcessor2D

Remarks

An InertiaProcessor2D object enables your application to extrapolate an element's location, orientation, and other properties by simulating real-world behavior.

For instance, when a user moves an element and then releases it, the element can continue moving, decelerate, and then slowly stop. An inertia processor implements this behavior by causing the affine 2-D values (origin, scale, translation, and rotation) to change over a specified time at a specified deceleration rate.

An inertia processor by itself does not cause an element to move and decelerate. Your application receives information from an inertia processor and applies the values as needed to an application-specific element. Typically, an application uses the information received from an inertia processor to change the location, size or orientation of an element.

Inertia processing is typically used in conjunction with manipulation processing. For more information, see the ManipulationProcessor2D class.

Constructors

InertiaProcessor2D()

Initializes a new instance of the InertiaProcessor2D class.

Properties

ExpansionBehavior	Gets or sets the expansion behavior of the inertia processor.
InitialOriginX	Gets or sets the x-coordinate for the initial origin, in coordinate units.
InitialOriginY	Gets or sets the y-coordinate for the initial origin, in coordinate units.
IsRunning	Gets whether inertia is currently in progress.
RotationBehavior	Gets or sets the rotation behavior of the inertia processor.
TranslationBehavior	Gets or sets the translation behavior of the inertia processor.

Methods

Complete(Int64)	Completes final extrapolation by using the specified timestamp and raises the Completed event.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Process(Int64)	Extrapolates the manipulation's position, orientation, and average radius at the specified time.
SetParameters(InertiaParameters2D)	Sets parameters on the inertia processor.
ToString()	Returns a string that represents the current object. (Inherited from Object)

Events

Completed	Occurs when extrapolation has completed.
Delta	Occurs when the extrapolation origin has changed or when translation, scaling, or rotation have occurred.
