A light that illuminates every targeted Visual equally.

A time-based animation that targets the Color property with one or more color key frames.

The ColorKeyFrameAnimation class is one of the supported types of KeyFrameAnimation s that is used to animate the Color property off of the Brush property on a SpriteVisual. When working with ColorKeyFrameAnimation s, utilize Windows.UI.Color objects for the values of keyframes. Utilize the InterpolationColorSpace property to define which color space the system will interpolate through for the animation.

Represents the base animation class.

Defines a group of animations.

CompositionAnimationGroup provides a way to group CompositionAnimation s in a list which will be started at the same time when StartAnimationGroup is called on CompositionObject. All ComositionAnimation in CompositionAnimationGroup need to assign a value to the Target property in the animation itself. CompositionAnimationGroup can also be associated with ImplicitAnimationCollection as an animation that gets executed as a result of a trigger.

Arguments for the CompositionCommitBatch.Completed or CompositionScopedBatch.Completed events.

Base class for brushes used to paint a SpriteVisual.

The CompositionEasingFunction class is the base class for easing functions that are used with KeyFrameAnimation s. Easing functions are used to describe how the system interpolates between two different keyframes. Currently, there are three supported easing functions: Linear, Cubic Bezier and Step.

Creates a composition object that contains a Win2D effect description format in the Microsoft.Graphics.Canvas.Effects namespace.

[Contains prerelease APIs.]
Base class of the composition API representing a node in the visual tree structure.

Composition objects are the visual tree structure on which all other features of the composition API use and build on. The API allows developers to define and create one or many Visual objects each representing a single node in a Visual tree.

Stores values as key-value pairs. CompositionPropertySet s are CompositionObject s that allow storage of key values pairs that can be shared across the application and are not tied to the lifetime of another composition object. CompositionPropertySet s are most commonly used with animations, where they maintain key-value pairs that are referenced to drive portions of composition animations. CompositionPropertySet s provide the ability to insert key-value pairs or retrieve a value for a given key. For more information on using CompositionPropertySet with animations, see the Animations Overview page.

An explicitly created group of active animations or effects.

Base class for shadows that can be applied to a SpriteVisual.

Paints a SpriteVisual with pixels from an ICompositionSurface.

Represents the window on which to display the composition tree.

Represents sparsely allocated bitmaps that can be associated with visuals for composition in a visual tree.

[Contains prerelease APIs.]
Manages the session between an application and the system compositor process.

The Compositor class creates an instance of the Compositor for the application that can be used as a factory for a variety of types in the Windows.UI.Composition namespace spanning the visual layer, effects system and animation system. The Compositor class also manages the lifetime of objects created from the factory.

A node in the visual tree that can have children.

Represents a cubic-bezier function for interpolating between animation key frames.

The cubic-bezier function is one of the more common easing functions used with KeyFrameAnimation s and are used frequently to describe smooth curves that can be scaled. Cubic-bezier functions are defined by two “control points” of type Vector2 that define the shape of the curve. When used, the animating property will change in between two keyframes based on the defined curve.

[Contains prerelease APIs.]
An infinitely large distant light source that emits light in a single direction. For example, a distant light could be used to represent sunlight.

[Contains prerelease APIs.]
A drop shadow cast by a SpriteVisual.

A Composition Animation that uses a mathematical equation to calculate the value for an animating property every frame.

A collection of animations triggered when a condition is met.

[Contains prerelease APIs.]
A collection of values that specify where an animation will start.

Clips a portion of a visual. The visible portion of the visual is a rectangle defined as inset values from the edges of the visual. The portion of the visual outside the rectangle is clipped.

InsetClips are defined using offsets from the bottom, left, right and top of the Visual to be clipped in pixels. It is possible to fully clip the entire Visual. Negative values are allowed. InsetClips support all the same transforms as Visuals except the 4x4 matrix. Unlike Visuals, InsetClips are 2D and are defined, instead, with a 3x2 matrix. InsetClip properties are fully animatible.

A time-based animation with one or more key frames. These frames are markers, allowing developers to specify values at specific times for the animating property. KeyFrame animations can be further customized by specifying how the animation interpolates between keyframes.

[Contains prerelease APIs.]
A ContainerVisual whose children are flattened into a single layer.

Represents a linear function for interpolating between animation key frames.

A time-based animation that targets the Orientation property with one or more key frames.

The QuaternionKeyFrameAnimation class is one of the supported types of KeyFrameAnimation s that is used to animate the Orientation property on a Visual. Quaternions are a useful and sometimes simpler way to think about rotations – Quaternions take the shortest path between angles and avoid issues like Gimbal Lock that rotation angle/axis and rotation matrices run into. A Quaternion is made up of two components: a scalar and vector part.
