Windows Phone 7 Image Controller: Zoom In, Zoom Out, and Rotate (WP 7 图像控制器：放大，缩
第一步： 下载 Silverlight for Windows Phone Toolkit - Nov 2010 安装的时候要暂时关闭VS (Visual Studio)， 安装完后，打开VS，添加参考（Add References): Microsoft.Phone.Controls.Toolkit第二步： 在WP 7 XAML文件中添加xmlns references:
xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"
第三步： 在XAML文件中设定image属性
第四步：在CS文件中编写相关的Event Handler：
//Pinch Event Hanlder, including rotation, scale
private void OnPinchStarted(object sender, PinchStartedGestureEventArgs e)
{
initialAngle = transform.Rotation;
initialScale = transform.ScaleX;
}
private void OnPinchDelta(object sender, PinchGestureEventArgs e)
{
transform.Rotation = initialAngle + e.TotalAngleDelta;
transform.ScaleX = initialScale * e.DistanceRatio;
transform.ScaleY = initialScale * e.DistanceRatio;
}
private void Postcard_ManipulationDelta(object sender, DragDeltaGestureEventArgs e)
{
//moving along X axis
transform.TranslateX += e.HorizontalChange;
//moving along Y axis
transform.TranslateY += e.VerticalChange;
}
}
}
搞定，我也是刚接触WP 7 编程，欢迎大家一起讨论学习。
