How do I acquire individual pages using ISIS Xpress .NET?

The ISIS Xpress BasicCapabilities and AdvancedCapabilities samples demonstrate a number of different ways to acquire images and save a batch of them to file, but how can I get a single image as soon as it gets acquired by the scanner?

During the ISIS Xpress Scanned() event, you can get the currently acquired page via the ISISXpress.Output property (i.e., – ISISXpress.Output.TransferTo() or ISISXpress.Output.ToHdib()).
