wpf 2d动画(DoubleAnimation PointAnimation ColorAnimation)

1.通过xamls设置动画

<StackPanel>
        <Rectangle Width="100" Height="100"  Name="r1">
                   <Rectangle.Fill>
                <SolidColorBrush Color="Blue" x:Name="s1"/>
            </Rectangle.Fill>
            <Rectangle.RenderTransform>
                <RotateTransform x:Name="rot1" CenterX="0" CenterY="0" Angle="0"/>
            </Rectangle.RenderTransform>
            <Rectangle.Triggers>
                <EventTrigger RoutedEvent="Window.Loaded">
                    <BeginStoryboard>
                        <Storyboard  >
                            <ColorAnimation AutoReverse="True"  Storyboard.TargetName="s1" Storyboard.TargetProperty="Color" From="Blue" To="Red" Duration="0:0:1" By="green"/>
                            <DoubleAnimation Storyboard.TargetName="rot1" Storyboard.TargetProperty="Angle" From="0" To="360" Duration="0:0:1">
                               
                                
                            </DoubleAnimation>
                        </Storyboard>
                    </BeginStoryboard>
                    
                </EventTrigger>
            </Rectangle.Triggers>
        </Rectangle>
        <Rectangle Width="10" Height="10" Fill="Yellow" Name="r2"></Rectangle>
       
    </StackPanel>

2.通过CLR (C#)设置动画

public Window1()
        {
            InitializeComponent();
            DoubleAnimation da = new DoubleAnimation(10, 100, new Duration(new TimeSpan(0, 0, 1)));
            DoubleAnimation da1 = new DoubleAnimation(10, 100, new Duration(new TimeSpan(0, 0, 1)));

            Storyboard.SetTargetProperty(da, new PropertyPath(Rectangle.WidthProperty));
            Storyboard.SetTargetProperty(da1, new PropertyPath(Rectangle.HeightProperty));
          
            Storyboard sb = new Storyboard();
            sb.Children.Add(da);
            sb.Children.Add(da1);
            sb.Begin(r2);
         }

3.也可以直接使用对象的BeginAnimation来启动动画

public Window1()
{
　　InitializeComponent();
　　DoubleAnimation da = new DoubleAnimation(10, 100, new Duration(new TimeSpan(0, 0, 1)));
　　r2.BeginAnimation(Rectangle.WidthProperty, da);
　　r2.BeginAnimation(Rectangle.HeightProperty, da);
}
