Silverlight—C#代码实现变形特效

代码很简单，没什么技术性，只是发出来做个知识累积

XAML：

 <Canvas x:Name="LayoutRoot" Background="White">
        <Image x:Name="img_jiqiren" Stretch="None" Source="../images/jiqiren2.jpg" Canvas.Left="177" Canvas.Top="0"></Image>
        <Button FontSize="18"  Content="旋转对象" Canvas.Left="278" Canvas.Top="142" Click="Button_Click" />
    </Canvas>

后台：

public partial class RenderTransformWithCSharp : UserControl
    {
        private int angle = 0;//声明旋转角度变量
        //声明旋转对象
        private RotateTransform rotate = new RotateTransform();
        public RenderTransformWithCSharp()
        {
            InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            //每次点击增加45度
            angle += 45;
            //指定旋转对象的角度
            rotate.Angle = angle;
            //设置旋转角度中心点
            rotate.CenterX = 100;
            rotate.CenterY = 100;
            //将旋转对象赋给UI变形对象
            img_jiqiren.RenderTransform = rotate;
        }
    }

运行结果：
