ScanningManagerEvents.SheetAcquired event

This event is raised for each sheet after the sheet has been scanned and digitized. At this point the sheet has passed basic integrity tests (digitization complete, light check, dark check, skew, and timing mark acquisition), but has not yet been identified.

The solution performs any per-sheet solution-specific initialization at this event. ScanEventArgs.Sheet.SheetNumber is undefined at this event; so do not base your initialization code on the members of ScanEventArgs.Sheet.

This event fires for all scanners.

• For OMR scanners: SheetAcquired is fired only if there is a sheet with timing marks. If a sheet is scanned and it does not have timing marks, a scanning error occurs.
• For Image scanners: SheetAcquired is fired as long as there is an image. This supports documents without timing marks.

If the sheet integrity test fails, the ScanError event is fired instead of this event.

ScanningManager.Ping returns L_STATE_SCANNING at this event.
