2：WPF 是基于MVVM模式的开发技术，可以让大多数控件直接绑定数据源和事件，同时支持双向绑定，即控件中的数据改变可以直接导致后台数据改变，而不需要写赋值代码。而传统的窗口和控件只有单项绑定，即只能从数据到控件，反过来的话，就要写代码赋值了。
3：WPF 绘制的表格是布局控件，用来布局的，不能直接连接数据源。要连接数据源的话，可以使用专门的数据表格控件。
WPF用RenderTransform实现，随便做了个，代码如下。
XAML
<Window x:Class="WpfApplication3.MainWindow"xmlns="
xmlns:x="
Title="MainWindow"
Height="350"
Width="525">
<Grid>
<Image Name="image" Source="/WpfApplication3component/Images/Hydrangeas.jpg">
<Image.RenderTransform>
<TransformGroup>
<RotateTransform x:Name="rt"/>
<ScaleTransform x:Name="st"/>
<TranslateTransform x:Name="tt"/>
</TransformGroup>
</Image.RenderTransform>
</Image>
<StackPanel Orientation="Horizontal"
Height="20">
<Button Name="btnScale1"
Content="缩小"
Click="btnScale1_Click" />
<Button Name="btnScale2"
Content="放大"
Click="btnScale2_Click" />
<Button Name="btnRotation1"
Content="左转"
Click="btnRotation1_Click" />
<Button Name="btnRotation2"
Content="右转"
Click="btnRotation2_Click" />
<Button Name="btnMove1"
Content="左移"
Click="btnMove1_Click" />
<Button Name="btnMove2"
Content="右移"
Click="btnMove2_Click" />
<Button Name="btnMove3"
Content="上移"
Click="btnMove3_Click"/>
<Button Name="btnMove4"
Content="下移"
Click="btnMove4_Click" />
</StackPanel>
</Grid>
</Window>
CS如下
