.SH NAME
|
|
sane\-sceptre \- SANE backend for SCEPTRE scanners
|
|
.SH DESCRIPTION
|
|
The
|
|
.B sane\-sceptre
|
|
library implements a SANE (Scanner Access Now Easy) backend that
|
|
provides access to Sceptre flatbed scanners. This backend should be
|
|
considered
|
|
.B beta-quality
|
|
software! Please report any strange behavior to the maintainer of the
|
|
backend or to the SANE mailing list.
|
|
.PP
|
|
At present, only one scanner is known to work with this backend:

|

Sceptre VividScan S1200 SCSI

.RE
|
|
|
|
The make of this scanner is KINPO, so other scanners from that manufacturer may also work (eg. the S600).
|
|
.SH OPTIONS
|
|
The options the backend supports can either be selected through command line
|
|
options to programs like
|
|
.BR scanimage (1)
|
|
or through GUI elements in
|
|
.BR xscanimage (1)
|
|
or
|
|
.BR xsane (1).
|
|
|
|
Valid command line options and their syntax can be listed by using
|
|
|

.TP
|
|
.B Scan Mode
|
|
|
|
.TP
|
|
.B \-\-mode Lineart|Halftone|Gray|Color
|
|
Selects the basic mode of operation of the scanner.
|
|
The
|
|
.I Lineart
|
|
and
|
|
.I Halftone
|
|
mode are black and white only (1 bit).
|
|
.I Gray
|
|
will produce 256 levels of gray (8 bits).
|
|
.I Color
|
|
will produce a 24 bits
|
|
color image. The scanner supports 30 bits internally but it only
|
|
exports 24.
|
|
|
|
.TP
|
|
.B \-\-resolution 50..1200
|
|
Selects the resolution for a scan. The scanner can do several
|
|
resolutions between 50 and 1200.
|
|
|
|
.TP
|
|
.B \-\-halftone\-pattern 1|2|3|4
|
|
Selects the pattern mode that is used in
|
|
.I Halftone
|
|
mode.
|
|
|
|
.TP
|
|
.B \-\-gamma\-correction Default|User Defined|High Density Printing|\
|
|
Low density printing|High contrast printing
|
|
controls the scanner internal gamma correction.
|
|
|
|
.TP
|
|
.B \-\-custom\-gamma
|
|
Allows the user to specify a gamma table (see the
|
|
next 3 parameters).
|
|
.I Color
|
|
mode only.
|
|
|
|
.TP
|
|
.B \-\-red\-gamma\-table
|
|
Can be used to download a user defined
|
|
gamma table for the red channel. The table must be 256 bytes long.
|
|
.I Color
|
|
mode only.
|
|
|
|
.TP
|
|
.B \-\-green\-gamma\-table
|
|
Can be used to download a user defined
|
|
gamma table for the green channel. The table must be 256 bytes long.
|
|
.I Color
|
|
mode only.
|
|
|
|
.TP
|
|
.B \-\-blue\-gamma\-table
|
|
Can be used to download a user defined gamma table
|
|
for the blue channel. The table must be 256 bytes long.
|
|
.I Color
|
|
mode only.
|
|
|
|
.TP
|
|
.B \-\-threshold 0..255
|
|
Sets the threshold for black and white pixels in
|
|
.I Lineart
|
|
mode. 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. The scan mode is user
|
|
selected. The default is "no".
|
|
|
|
.TP
|
|
.B The geometry options
|
|
|
|
.TP
|
|
.B \-l \-t \-x \-y
|
|
control the scan area:
|
|
.B -l
|
|
sets the top left x coordinate,
|
|
.B \-t
|
|
the top left y coordinate,
|
|
.B \-x
|
|
selects the width and
|
|
.B \-y
|
|
the height of the scan area. All parameters are specified in millimeters by default.
|
|
|
|
|
|
.SH CONFIGURATION FILE
|
|
The configuration file
|
|
.I @CONFIGDIR@/sceptre.conf
|
|
supports only one item: the device name to use
|
|
.RI "(eg " /dev/scanner ).
|
|
|
|
|
|
.SH FILES
|
|
.TP
|
|
.I @LIBDIR@/libsane\-sceptre.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane\-sceptre.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
|
|
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B SANE_DEBUG_SCEPTRE
|
|
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.
|
|
|
|
|
|
.SH LIMITATIONS
|
|
.TP
|
|
.B Resolutions
|
|
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.
|
|
|
|
|
|

|
