FrameSegmentNumber Property

Number of the (partial) segment in this frame, starting at 1. When running in TriggerMode.TMNone or TriggerMode.TMSingle, only one segment is ever created. When running in TriggerMode.TMContinuous or TriggerMode.TMMultiSegment, each segment (starting at TriggerOnSignal and stopping at TriggerOffSignal) will increment the segment number.
