This is a very rich collection of Win2D based helper classes and controls for Windows Composition. When looking for more advanced extension methods for CanvasPathBuilder, I came across the CompositionProToolkit by Ratish Philip. Getting some help from CompositionProToolkit The old clock successfully upgraded from straight rectangles to rounded ones, ellipses, and lines. The –smooth- animations to redraw the hour, minute, and seconds hands act at CompositionObject level –the base class of all visual composition objects-, so there was no need to modify from the original clock here. _secondhandSpriteShape = _compositor.CreateSpriteShape(pathGeometry) Var pathGeometry = _compositor.CreatePathGeometry() Var compositionPath = new CompositionPath(canvasGeometry) Var canvasGeometry = CanvasGeometry.CreatePath(canvasPathBuilder) Var canvasPathBuilder = new CanvasPathBuilder(new CanvasDevice()) ĬanvasPathBuilder.BuildPathWithLines(new(float x, float y) Fortunately I came across this blog post by Daren May where he shares an extension method on CanvasPathBuilder to build a path with lines: The constructor of CompositionPath requires a IGeometrySource2D instance, which brings you pretty close to the Win2D primitives (and out of my enterprise XAML developer comfort zone). Drawing it was a little bit harder than expected. The seconds hand is a triangle made out of three lines. HandShapeVisual.Size = new Vector2(200.0f, 200.0f) HandShapeVisual = _compositor.CreateShapeVisual() _hourhandSpriteShape.CenterPoint = new Vector2(3.0f, 60.0f) _hourhandSpriteShape.Offset = new Vector2(97.0f, 40.0f) _hourhandSpriteShape.FillBrush = _compositor.CreateColorBrush(Colors.DarkSlateGray) _hourhandSpriteShape = _compositor.CreateSpriteShape(roundedRectangle) RoundedRectangle.CornerRadius = new Vector2(3.0f, 3.0f) RoundedRectangle.Size = new Vector2(6.0f, 63.0f) Var roundedRectangle = _compositor.CreateRoundedRectangleGeometry()

a simple shape – a triangle- for the seconds hand.Įverything is done with the Composition API, the only XAML is.

rounded rectangles for hour and minute hands, and.

ellipses as background face and hour ticks,.

The upgraded clock control is a custom user control that has I didn’t have to start from scratch, I upgraded an existing project that used rectangles and images:

To demonstrate these new classes I built a Clock UserControl that’s made of ellipses and rounded rectangles drawn and animated by Windows Composition.

ShapeVisual, the XAML visual tree node that hosts the image.

CompositionContainerShape that hosts a group of sprites with common transforms, and.

CompositionSpriteShape that draws the geometry,.

CompositionGeometry and its child classes that define the geometry,.

In this article we’ll stick to the new classes that were added to display shapes: Please refer to one of my previous blog posts for an introduction to the core concepts.

In this article I will not dive too much in detail on how to draw and animate Composition sprites in XAML. for drawing controls or for animating content à la Lottie.

This is good news for developers who want to use more of Windows Composition in their apps, e.g.

#HOW TO USE ANIMATION COMPOSER 2 UPDATE#

The latest update does more than rectangles: it supports shapes from lines and ellipses to rounded rectangles and even SVG paths.

#HOW TO USE ANIMATION COMPOSER 2 WINDOWS 10#

Before the April Windows 10 Update, this API was limited to drawing rectangles that you could fill with a brush or an image. This article explains how you can use the Composition API to display and animate geometric shapes in a UWP app.
