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
14 At present, only one scanner is known to work with this backend:
15
16 Model Connection Type
17 --------------------------- -------------------
18 Sceptre VividScan S1200 SCSI
19
20 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(1) or through GUI elements in
26 xscanimage(1) or xsane(1).
27
28 Valid command line options and their syntax can be listed by using
29
30 scanimage --help -d sceptre
31
32
33 Scan Mode
34
35
36 --mode Lineart|Halftone|Gray|Color
37 Selects the basic mode of operation of the scanner. The Lineart
38 and Halftone mode are black and white only (1 bit). Gray will
39 produce 256 levels of gray (8 bits). Color will produce a 24
40 bits color image. The scanner supports 30 bits internally but it
41 only exports 24.
42
43
44 --resolution 50..1200
45 Selects the resolution for a scan. The scanner can do several
46 resolutions between 50 and 1200.
47
48
49 --halftone-pattern 1|2|3|4
50 Selects the pattern mode that is used in Halftone mode.
51
52
53 --gamma-correction Default|User Defined|High Density Printing|Low den‐
54 sity printing|High contrast printing
55 controls the scanner internal gamma correction.
56
57
58 --custom-gamma
59 Allows the user to specify a gamma table (see the next 3 parame‐
60 ters). Color mode only.
61
62
63 --red-gamma-table
64 Can be used to download a user defined gamma table for the red
65 channel. The table must be 256 bytes long. Color mode only.
66
67
68 --green-gamma-table
69 Can be used to download a user defined gamma table for the green
70 channel. The table must be 256 bytes long. Color mode only.
71
72
73 --blue-gamma-table
74 Can be used to download a user defined gamma table for the blue
75 channel. The table must be 256 bytes long. Color mode only.
76
77
78 --threshold 0..255
79 Sets the threshold for black and white pixels in Lineart mode.
80 Possible values are from 0 (darker) to 255 (lighter).
81
82
83 --preview
84 Requests a preview scan. The resolution used for that scan is 30
85 dpi and the scan area is the maximum allowed. The scan mode is
86 user selected. The default is "no".
87
88
89 The geometry options
90
91
92 -l -t -x -y
93 control the scan area: -l sets the top left x coordinate, -t the
94 top left y coordinate, -x selects the width and -y the height of
95 the scan area. All parameters are specified in millimeters by
96 default.
97
98
99
101 The configuration file /etc/sane.d/sceptre.conf supports only one item:
102 the device name to use (eg /dev/scanner).
103
104
105
107 /usr/lib64/sane/libsane-sceptre.a
108 The static library implementing this backend.
109
110 /usr/lib64/sane/libsane-sceptre.so
111 The shared library implementing this backend (present on systems
112 that support dynamic loading).
113
114
115
117 SANE_DEBUG_SCEPTRE
118 If the library was compiled with debug support enabled, this
119 environment variable controls the debug level for this backend.
120 E.g., a value of 128 requests all debug output to be printed.
121 Smaller levels reduce verbosity.
122
123
124
126 Resolutions
127 The windows TWAIN driver can be set to any resolution between 50
128 to 1200 (excluding software interpolation). This backend cannot.
129 Only a handful of resolution are available, although they should
130 be numerous enough.
131
132
133
135 None known.
