Wpf 动画图像按钮

我需要一个自定义图像按钮，我已经使用了一段时间的帮助。它工作得很好，但我不知道如何在正常、鼠标悬停、按下这三种状态下设置按钮的动画：

正常到鼠标悬停 鼠标悬停 我对XAML没有那么熟练，所以我想不出来。不管怎样，下面是我一直在使用的代码：

<Button Height="40" HorizontalAlignment="Left" IsEnabled="True" IsHitTestVisible="True" Margin="262,219,0,0" Name="home_btn" VerticalAlignment="Top" Width="89">
    <Button.Template>
        <ControlTemplate TargetType="{x:Type Button}">
            <Grid>
                <Image Name="Normal" Source="normal.png" />
                <Image Name="Hover" Source="hover.png" Visibility="Hidden" />
                <Image Name="Pressed" Source="pressed.png" Visibility="Hidden" />
            </Grid>
            <ControlTemplate.Triggers>
                <Trigger Property="ButtonBase.IsPressed" Value="True">
                    <Setter Property="UIElement.Visibility" TargetName="Normal" Value="Hidden" />
                    <Setter Property="UIElement.Visibility" TargetName="Pressed" Value="Visible" />
                </Trigger>
                <Trigger Property="UIElement.IsMouseOver" Value="True">
                    <Setter Property="UIElement.Visibility" TargetName="Normal" Value="Hidden" />
                    <Setter Property="UIElement.Visibility" TargetName="Hover" Value="Visible" />
                </Trigger>
            </ControlTemplate.Triggers>
        </ControlTemplate>
    </Button.Template>
</Button>
