sane-leo(5)		 SANE Scanner Access Now Easy		   sane-leo(5)

NAME
       sane-leo - SANE backend for LEO Technologies scanners

DESCRIPTION
       The  sane-leo library implements a SANE (Scanner Access Now Easy) back‐
       end that provides access to some LEO SCSI flatbed scanners. This	 back‐
       end  should be considered beta-quality software! LEO scanners were also
       sold under the Across Technologies brand.

       The scanners that should work with this backend are:

		 Vendor Model		status
	      ----------------------  -----------
		Across FS-1130		tested
		Leo S3			tested

       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.

       If you have any strange behavior, please report to  the	backend	 main‐
       tainer or to the SANE mailing list.

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

       Scan Mode

       --mode selects the basic mode of operation of the scanner valid choices
	      are Black & White , Grayscale and Color The Black &  White  mode
	      is black and white only (1 bit). Grayscale will produce 256 lev‐
	      els of gray (8 bits). Color will produce a 24 bits color image.

       --resolution
	      selects the resolution for a scan. The scanner can do all	 reso‐
	      lutions between 1 and 300, in increments of 1.

       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
	      default.

       Enhancement options

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

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

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

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

       --halftone
	      (Black & White only) select the halftone mask to	use.  Possible
	      values are Diamond , 8x8 Coarse Fatting , 8x8 Fine Fatting , 8x8
	      Bayer and 8x8 Vertical Line

       --preview
	      requests a preview scan. The resolution used for that scan is 28
	      dpi  and	the scan area is the maximum allowed. The scan mode is
	      user selected. The default is "no".

CONFIGURATION FILE
       The configuration file /etc/sane.d/leo.conf supports only one  informa‐
       tion: the device name to use (eg /dev/scanner).

FILES
       /usr/lib/sane/libsane-leo.a
	      The static library implementing this backend.

       /usr/lib/sane/libsane-leo.so
	      The shared library implementing this backend (present on systems
	      that support dynamic loading).

ENVIRONMENT
       SANE_DEBUG_LEO
	      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.

LIMITATIONS
       The  windows TWAIN driver has many more options than this SANE backend.
       However they are only software adjustments. This	 backend  only	imple‐
       ments what the scanner can support.

BUGS
       None known.
