.SH NAME
|
|
sane\-leo \- SANE backend for LEO Technologies scanners
|
|
.SH DESCRIPTION
|
|
The
|
|
.B sane\-leo
|
|
library implements a SANE (Scanner Access Now Easy) backend that
|
|
provides access to some LEO SCSI flatbed scanners. This backend
|
|
should be considered
|
|
.B beta-quality
|
|
software! LEO scanners were also sold under the Across Technologies brand.
|
|
.PP
|
|
The scanners that should work with this backend are:
|
|
.PP
|
|
.RS
|
|
.ft CR
|
|
.nf

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).
|
|
|
|
.br
|
|
If you have any strange behavior, please report to the backend
|
|
maintainer or to the SANE mailing list.
|
|
|
|
Valid command line options and their syntax can be listed by using
|
|

|
|
.B Scan Mode
|
|
|
|
.TP
|
|
.B \-\-mode
|
|
selects the basic mode of operation of the scanner. Valid choices are
|
|
.IR "Black & White" ,
|
|
.I Grayscale
|
|
and
|
|
.IR Color .
|
|
The
|
|
.I Black & White
|
|
mode is black and white only (1 bit).
|
|
.I Grayscale
|
|
mode will produce 256 levels of gray (8 bits).
|
|
.I Color
|
|
mode will produce a 24 bit color image.
|
|
|
|
.TP
|
|
.B \-\-resolution
|
|
selects the resolution for a scan. The scanner can do all resolutions
|
|
between 1 and 300, in increments of 1.
|
|
|
|
|
|
.TP
|
|
.B Geometry options
|
|
|
|
.TP
|
|
.B \-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.

.TP
|
|
.B Enhancement options
|
|
|
|
.TP
|
|
.B \-\-custom\-gamma
|
|
(grayscale and color mode only) allows the user to specify a gamma table (see the
|
|
next 3 parameters).
|
|
|
|
.TP
|
|
.B \-\-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.
|
|
|
|
.TP
|
|
.B \-\-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.
|
|
|
|
.TP
|
|
.B \-\-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.
|
|
|
|
.TP
|
|
.B \-\-halftone
|
|
(Black & White only) select the halftone mask to use. Possible values are
|
|
.IR Diamond ,
|
|
.IR "8x8 Coarse Fatting" ,
|
|
.IR "8x8 Fine Fatting" ,
|
|
.I 8x8 Bayer
|
|
and
|
|
.IR "8x8 Vertical Line" .
|
|
|
|
.TP
|
|
.B \-\-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".
|
|
|
|
|
|
.SH CONFIGURATION FILE
|
|
The configuration file
|
|
.I @CONFIGDIR@/leo.conf
|
|
supports only one information: the device name to use (eg
|
|
.IR /dev/scanner ).
|
|
|
|
|
|
.SH FILES
|
|
.TP
|
|
.I @LIBDIR@/libsane\-leo.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane\-leo.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
|
|
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B 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.
|
|
|
|
|
|
.SH LIMITATIONS
|
|
The windows TWAIN driver has many more options than this SANE
|
|
backend. However they are only software adjustments. This backend only
|
|
implements what the scanner can support.
|
|
|
|
|
|
.SH BUGS
|
|
None known.
