The scanner supports 30 bits internally but it only +exports 24. + +.TP +.B \-\-resolution 50..1200 +Selects the resolution for a scan.

Possible values are from 0 (darker) to 255 (lighter). + +.TP +.B \-\-preview +Requests a preview scan. The resolution used for that scan is 30 dpi +and the scan area is the maximum allowed.
