„Zd„Zd„Zd„ZRS(sClass representing a SANE device.
    Methods:
    startScan()    -- initiate a scan, using the current settings
    cancelScan()   -- cancel an in-progress scanning operation

    Also available, but rather low-level:
    getParameters() -- get the current parameter settings of the device
    getOptions()    -- return a list of tuples describing all the options.

    Attributes:
    optlist -- list of option names

    You can also access an option name to retrieve its value, and to
    set it.  For example, if one option has a .name attribute of
    imagemode, and scanner is a ScanDevice object, you can do:
         print scanner.imagemode
         scanner.imagemode = 'Full frame'
         scanner.['imagemode'] returns the corresponding Option object.

           (format, format_name, last_frame, (pixels_per_line, lines), depth, bytes_per_line)

            - format is the SANE frame type
            - format is one of 'grey', 'color' (RGB), 'red', 'green', 'blue'.
            - last_frame [bool] indicates if this is the last frame of a multi frame image
            - (pixels_per_line, lines) specifies the size of the scanned image (x,y)
            - lines denotes the number of scanlines per frame
            - depth gives number of pixels per sample
