       sane-sceptre - SANE backend for SCEPTRE scanners

       The  sane-sceptre  library  implements a SANE (Scanner Access Now Easy)
       backend that provides access to Sceptre flatbed scanners. This  backend
       should  be  considered beta-quality software! Please report any strange
       behavior to the maintainer of the backend or to the SANE mailing list.

       At present, only one scanner is known to work with this backend:

	      Model			   Connection Type
	      ---------------------------  -------------------
	      Sceptre VividScan S1200	   SCSI

       The make of this scanner is KINPO, so other scanners from that manufac‐
       turer may also work (eg. the S600).

       The options the backend supports can either be selected through command
       line options to programs like scanimage	or  through  GUI  elements  in
       xscanimage or xsane.

       Valid command line options and their syntax can be listed by using
	      scanimage --help -d sceptre

       Scan Mode

       --mode selects the basic mode of operation of the scanner valid choices
	      are Lineart, Halftone, Gray and Color.  The Lineart and Halftone
	      mode  are	 black	and  white only (1 bit). Gray will produce 256
	      levels of gray (8 bits). Color will  produce  a  24  bits	 color
	      image.  The  scanner  supports  30  bits	internally but it only
	      exports 24.

	      selects the resolution for a scan. The scanner  can  do  several
	      resolutions between 50 and 1200.

	      selects  the  pattern  mode that is used in Halftone mode. Valid
	      options are 1, 2, 3 and 4.

	      controls the scanner internal gamma  correction.	Valid  options
	      are "Default", "User defined", "High density printing" "Low den‐
	      sity printing" and "High contrast printing".

	      (color mode only) allows the user to specify a gamma table  (see
	      the next 3 parameters).

	      (color  mode  only) can be used to download a user defined gamma
	      table for the red channel. The table must be 256 bytes long.

	      (color mode only) can be used to download a user	defined	 gamma
	      table for the green channel. The table must be 256 bytes long.

	      (color  mode  only) can be used to download a user defined gamma
	      table for the blue channel. The table must be 256 bytes long.

	      sets the threshold for black and white pixels in	lineart	 mode.
	      Possible values are from 0 (darker) to 255 (lighter).

	      requests a preview scan. The resolution used for that scan is 30
	      dpi and the scan area is the maximum allowed. The scan  mode  is
	      user selected. The default is "no".

       The geometry options

       -l -t -x -y
	      control the scan area: -l sets the top left x coordinate, -t the
	      top left y coordinate, -x selects the width and -y the height of
	      the  scan	 area.	All parameters are specified in millimeters by

       The	 configuration	      file	  /system/resources/sane-back‐
       ends/1.0.18/etc/sane.d/sceptre.conf  supports only one information: the
       device name to use (eg /dev/scanner).

	      The static library implementing this backend.

	      The shared library implementing this backend (present on systems
	      that support dynamic loading).

	      If  the  library	was  compiled with debug support enabled, this
	      environment variable controls the debug level for this  backend.
	      E.g.,  a	value  of 128 requests all debug output to be printed.
	      Smaller levels reduce verbosity.

	      The windows TWAIN driver can be set to any resolution between 50
	      to 1200 (excluding software interpolation). This backend cannot.
	      Only a handful of resolution are available, although they should
	      be numerous enough.

       None known.

       The package is actively maintained by Frank Zago.
