The following shows how to create a DoubleAnimation in code. The following shows how to create a DoubleAnimation in XAML.

To make the animation transition from 1.0 to 0.0 you set its From property to 1.0 and its To property to 0.0. To specify its ending value, you set its To property.ДЄn opacity value of 1.0 makes the object completely opaque, and an opacity value of 0.0 makes it completely invisible. To specify its starting value, you set its From property. A DoubleAnimation creates a transition between two double values. Because the Opacity property is of type Double, you need an animation that produces double values. One way to make an element fade in and out of view is to animate its Opacity property. Me.RegisterName(myRectangle.Name, myRectangle) This.RegisterName(myRectangle.Name, myRectangle)

The following shows how to create a Rectangle element in a StackPanel in code. The following shows how to create a Rectangle element in a StackPanel in XAML. The steps that follow show how to create an animation and apply it to the rectangle's Opacity property. The first part of the example creates a Rectangle element. As a result, the Rectangle fades in and out of view. It uses a DoubleAnimation, which is a type of animation that generates Double values, to animate the Opacity property of a Rectangle. This example shows how to use a WPF animation to animate the value of a dependency property. Animations do not have to be visual you can animate objects that are not part of the user interface if they meet the criteria that are described in this section.Д®xample: Make an Element Fade In and Out of View You can use animations almost anywhere, which includes in styles and control templates. Most of their properties are dependency properties. Controls such as Button and TabControl, and also Panel and Shape objects inherit from DependencyObject. WPF contains many objects that have IAnimatable properties. (If WPF does not provide one, you can create your own. There must be a compatible animation type available. It must belong to a class that inherits from DependencyObject and implements the IAnimatable interface. To make an object fade from view, you animate its Opacity property.ДЇor a property to have animation capabilities, it must meet the following three requirements: For example, to make a framework element grow, you animate its Width and Height properties. Most important is that, in WPF, you animate objects by applying animation to their individual properties. If you understand a few important concepts about the timing system, WPF animations can be easier to use. These custom animations gain many of the performance benefits of the standard animation classes. WPF also makes it easy to create your own animations by exposing animation base classes from which your classes can inherit, to produce customized animations. It provides timing classes that enable you to focus on the effects you want to create, instead of the mechanics of achieving those effects. WPF handles all the behind-the-scenes work of managing a timing system and redrawing the screen efficiently. WPF animation makes it easy to animate controls and other graphical objects.

WPF includes an efficient timing system that is exposed through managed code and WPF framework.

Prior to WPF, Microsoft Windows developers had to create and manage their own timing systems or use special custom libraries. The program then updates the rectangle with the new value and redraws it. The program checks the timer at set intervals to see how much time has elapsed.Д®ach time the program checks the timer, it computes the current opacity value for the rectangle based on how much time has elapsed. For example, a program that makes a drawing of a rectangle fade out of view might work as follows. When the frames are played back by a projector, the audience sees a moving picture.ДЄnimation on a computer is similar. In film, this illusion is created by using cameras that record many photographs, or frames, each second. The brain perceives the group of images as a single changing scene.

It focuses on the animation of WPF objects by using storyboards.ДЄnimation is an illusion that is created by quickly cycling through a series of images, each slightly different from the last. This overview provides an introduction to the WPF animation and timing system. By just animating a background color or applying an animated Transform, you can create dramatic screen transitions or provide helpful visual cues.

Animation can make an attractive user interface even more spectacular and usable. Windows Presentation Foundation (WPF) provides a powerful set of graphics and layout features that enable you to create attractive user interfaces and appealing documents.
