The following code sample shows how to set the rotation on an orientation event: Based on the set rotation, each use case will either rotate the image data or portrait. This is helpful if you want to display zoom ratio text alongside a slider. In addition, if you set a new zoom value while the previous operation is still executing, the previous zoom operation's ListenableFuture fails immediately. match the aspect ratios requested as closely as the device supports.
