C# 如何通过WPF动画使图像变大（产生选择的错觉）？

我对WPF非常陌生，甚至对WPF中的动画也比较新。我知道有故事板等，但我正在寻找一个具体的效果，所以我可以从那里工作，修补它

有谁能给我一个简单的例子，关于图像控件MouseDown（因为WPF中的这个控件中没有单击事件）通过一个漂亮的动画使图像变大

谢谢兄弟们。

这里有一个例子，可以满足我的要求：

<Window x:Class="WpfApplication.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="600" Width="600">
    <Window.Resources>
        <Storyboard x:Key="ScaleImageStoryboard">
            <DoubleAnimation Duration="0:0:0.5" From="300" To="400" Storyboard.TargetName="Image" Storyboard.TargetProperty="Height"/>
            <DoubleAnimation Duration="0:0:0.5" From="300" To="400" Storyboard.TargetName="Image" Storyboard.TargetProperty="Width"/>
        </Storyboard>
    </Window.Resources>
    <Grid>
        <Image Name="Image" Source="C:\Users\Public\Pictures\Sample Pictures\Desert.jpg" Stretch="Fill" Width="300" Height="300">
            <Image.Triggers>
                <EventTrigger RoutedEvent="Image.MouseDown">
                    <BeginStoryboard Storyboard="{StaticResource ScaleImageStoryboard}"/>
                </EventTrigger>
            </Image.Triggers>
        </Image>
    </Grid>
</Window>

在这里，图像从300x300像素开始。当Image.MouseDown事件被触发时，触发器将启动故事板，在半秒内将图像大小更改为400x400

但是，如果您想要的效果只是暂时影响图像的大小，而不影响布局，则可以使用：

<Window x:Class="WpfApplication.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="600" Width="600">
    <Window.Resources>
        <Storyboard x:Key="ScaleImageStoryboard">
            <DoubleAnimation Duration="0:0:0.2" From="1" To="1.2" AutoReverse="True"
                             Storyboard.TargetName="ScaleImage" Storyboard.TargetProperty="ScaleX"/>
            <DoubleAnimation Duration="0:0:0.2" From="1" To="1.2" AutoReverse="True" 
                             Storyboard.TargetName="ScaleImage" Storyboard.TargetProperty="ScaleY"/>
        </Storyboard>
    </Window.Resources>
    <Grid>
        <Image Name="Image" Source="C:\Users\Public\Pictures\Sample Pictures\Desert.jpg" 
               Stretch="Fill" Width="300" Height="300"
               RenderTransformOrigin="0.5, 0.5">
            <Image.RenderTransform>
                <ScaleTransform x:Name="ScaleImage"/>
            </Image.RenderTransform>
            <Image.Triggers>
                <EventTrigger RoutedEvent="Image.MouseDown">
                    <BeginStoryboard Storyboard="{StaticResource ScaleImageStoryboard}"/>
                </EventTrigger>
            </Image.Triggers>
        </Image>
    </Grid>
</Window>

以下内容将相对于图像的当前大小缩放图像，而不是更改绝对值。这可能更灵活

<Page xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>
  <Image x:Name="MyImage" Source="c:\myImage.jpg" Width="250" Height="250">
    <Image.RenderTransform>
      <ScaleTransform x:Name="ImageScale" ScaleX="1" ScaleY="1" RenderTransformOrigin="0.5, 0.5"/>
    </Image.RenderTransform>
    <Image.Triggers>
      <EventTrigger RoutedEvent="Image.MouseDown">
        <BeginStoryboard>
          <Storyboard>
            <DoubleAnimation Storyboard.TargetName="ImageScale" Storyboard.TargetProperty="(ScaleTransform.ScaleX)" To="1.5" Duration="0:0:0.25" AutoReverse="True"/>
            <DoubleAnimation Storyboard.TargetName="ImageScale" Storyboard.TargetProperty="(ScaleTransform.ScaleY)" To="1.5" Duration="0:0:0.25" AutoReverse="True"/>
          </Storyboard>
        </BeginStoryboard>
      </EventTrigger>
    </Image.Triggers>
  </Image>
</Page>
