Parameters
- control 
 Type: Microsoft.VisualStudio.TestTools.UITesting.UITestControl- Control on which the pinch gesture is to be performed. 
- relativePoint1
 Type: Microsoft.VisualStudio.TestTools.UITest.Input.Point
- relativePoint2
 Type: Microsoft.VisualStudio.TestTools.UITest.Input.Point
- distanceToMove 
 Type: UInt32- The distance each finger moves toward each other in pixels. 
Remarks
Playback of a pinch gesture depends on screen resolution. If the resolution changes, the parameters may have to be changed.
