WPF窗体由小到大最基本的写法

1：建立WPF的窗体

<Window x:Class="IShiTong.Project.WpfChart.Common.PanelWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="DialogWin" Height="635 " Width="635
        " WindowStyle="None" 
     Name="DW1"   Background="#00E86565" AllowsTransparency="True" WindowStartupLocation="CenterScreen" WindowState="Normal">
    <Window.Resources>
        <!--此样式能去除按钮点击后的虚线框-->
        <Style x:Key="MyFocusVisual">
            <Setter Property="Control.Template">
                <Setter.Value>
                    <ControlTemplate>
                        <Rectangle Margin="-2" StrokeThickness="0" Stroke="Red" StrokeDashArray="1 2"/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>
        <Canvas Height="220" Width="200" Canvas.Left="9" Canvas.Top="14" Name="Canvas1" VerticalAlignment="Center">
            <!--设置动画-->
            <Canvas.RenderTransform>
                <TransformGroup>
                    <ScaleTransform CenterX="100" CenterY="50"></ScaleTransform>
                </TransformGroup>
            </Canvas.RenderTransform>
        <Canvas.Background>
            <ImageBrush ImageSource="/IShiTong.Project.WpfChart.Common;component/Images/back.jpg" />
        </Canvas.Background>
    </Canvas>
</Window>

2：在PanelWindow.xaml.cs中写入基本的动画

/// <summary>
    /// PanelWindow.xaml 的交互逻辑
    /// </summary>
