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
--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
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
(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 /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.
