6 sane-sceptre - SANE backend for SCEPTRE scanners
7
9 The sane-sceptre library implements a SANE (Scanner Access Now Easy)
10 backend that provides access to Sceptre flatbed scanners. This backend
11 should be considered beta-quality software! Please report any strange
12 behavior to the maintainer of the backend or to the SANE mailing list.
13 At present, only one scanner is known to work with this backend:
15 Model Connection Type
17 --------------------------- -------------------
18 Sceptre VividScan S1200 SCSI
19 The make of this scanner is KINPO, so other scanners from that manufac‐
21 turer may also work (eg. the S600).
22
24 The options the backend supports can either be selected through command
25 line options to programs like scanimage or through GUI elements in
26 xscanimage or xsane.
27 Valid command line options and their syntax can be listed by using
29 scanimage --help -d sceptre
30 Scan Mode
33 --mode selects the basic mode of operation of the scanner valid choices
36 are Lineart, Halftone, Gray and Color. The Lineart and Halftone
37 mode are black and white only (1 bit). Gray will produce 256
38 levels of gray (8 bits). Color will produce a 24 bits color
39 image. The scanner supports 30 bits internally but it only
40 exports 24.
41 --resolution
44 selects the resolution for a scan. The scanner can do several
45 resolutions between 50 and 1200.
46 --halftone-pattern
49 selects the pattern mode that is used in Halftone mode. Valid
50 options are 1, 2, 3 and 4.
51 --gamma-correction
54 controls the scanner internal gamma correction. Valid options
55 are "Default", "User defined", "High density printing" "Low den‐
56 sity printing" and "High contrast printing".
57 --custom-gamma
60 (color mode only) allows the user to specify a gamma table (see
61 the next 3 parameters).
62 --red-gamma-table
65 (color mode only) can be used to download a user defined gamma
66 table for the red channel. The table must be 256 bytes long.
67 --green-gamma-table
70 (color mode only) can be used to download a user defined gamma
71 table for the green channel. The table must be 256 bytes long.
72 --blue-gamma-table
75 (color mode only) can be used to download a user defined gamma
76 table for the blue channel. The table must be 256 bytes long.
77 --threshold
80 sets the threshold for black and white pixels in lineart mode.
81 Possible values are from 0 (darker) to 255 (lighter).
82 --preview
85 requests a preview scan. The resolution used for that scan is 30
86 dpi and the scan area is the maximum allowed. The scan mode is
87 user selected. The default is "no".
88 The geometry options
91 -l -t -x -y
94 control the scan area: -l sets the top left x coordinate, -t the
95 top left y coordinate, -x selects the width and -y the height of
96 the scan area. All parameters are specified in millimeters by
97 default.
98
102 The configuration file /etc/sane.d/sceptre.conf supports only one
103 information: the device name to use (eg /dev/scanner).
104
108 /usr/lib64/sane/libsane-sceptre.a
109 The static library implementing this backend.
110 /usr/lib64/sane/libsane-sceptre.so
112 The shared library implementing this backend (present on systems
113 that support dynamic loading).
114
118 SANE_DEBUG_SCEPTRE
119 If the library was compiled with debug support enabled, this
120 environment variable controls the debug level for this backend.
121 E.g., a value of 128 requests all debug output to be printed.
122 Smaller levels reduce verbosity.
123
127 Resolutions
128 The windows TWAIN driver can be set to any resolution between 50
129 to 1200 (excluding software interpolation). This backend cannot.
130 Only a handful of resolution are available, although they should
131 be numerous enough.
132
136 None known.
