七、变换和投射

变换包括旋转、缩放和平移

第一，旋转

<Button Content="Button" HorizontalAlignment="Left" Margin="308,163,0,0" VerticalAlignment="Top" Height="123" Width="283" >
            <Button.RenderTransform>
                <RotateTransform Angle="70" CenterX="30" CenterY="30"></RotateTransform>
            </Button.RenderTransform>
        </Button>

Angle：表示旋转的度数

 CenterX  和CenterY 表示以那个位置旋转

第二，缩放

  <Button Content="Button" HorizontalAlignment="Left" Margin="308,163,0,0" VerticalAlignment="Top" Height="123" Width="283" >
            <Button.RenderTransform>
                
                <ScaleTransform ScaleX="3" ScaleY="5"></ScaleTransform>
            </Button.RenderTransform>
        </Button>

ScaleX和ScaleY表示缩放的倍数，如果ScaleY=-1，那么按钮就倒置了

第三，平移

 <Button Content="Button" HorizontalAlignment="Left" Margin="308,163,0,0" VerticalAlignment="Top" Height="123" Width="283" >
            <Button.RenderTransform>
           <TranslateTransform X="-100" Y="300"></TranslateTransform>
            </Button.RenderTransform>
        </Button>

第四，投射

<Image HorizontalAlignment="Left" Height="199" Margin="849,385,0,0" VerticalAlignment="Top" Width="175" Source="Assets/Logo.png">
            <Image.Projection>
                <PlaneProjection RotationY="70"></PlaneProjection>
            </Image.Projection>
        </Image>

 RotationY="70”表示图片围绕Y轴旋转70度
