6 sane-matsushita - SANE backend for Panasonic KV-SS high speed scanners
7
9 The sane-matsushita library implements a SANE (Scanner Access Now Easy)
10 backend that provides access to some Panasonic KV-SS high speed scan‐
11 ners. This backend is stable.
12 At present, the following scanners are known to work with this backend:
14 Product id
16 --------------
17 KV-SS25
18 KV-SS25D
19 KV-SS55EX (*)
20 KV-S2025C (*)
21 KV-S2045C (*)
22 KV-S2065L (*)
23 (*) WARNING: None of the advanced options of these scanners are avail‐
25 able (ie no color, no high resolution, no automatic cropping). Basi‐
26 cally, the driver does no more than what it does for the KV-SS25. I
27 don't have access to such scanners, and thus cannot add these options.
28 Other Panasonic high speed scanners may or may not work with that back‐
30 end.
31 Valid command line options and their syntax can be listed by using
33 scanimage --help -d matsushita
34 Scan Mode
37 --mode selects the basic mode of operation of the scanner.
40 --resolution
42 selects the resolution for a scan. Each model supports all or a
43 subset of these resolutions: 100, 150, 200, 240, 300, 360, 400.
44 --duplex
46 indicates whether to scan both side of the sheet.
47 --feeder-mode
49 selects the number of pages to scan (one or until the tray is
50 empty).
51 Geometry
54 --paper-size A4|...|Legal|Letter [A4]
57 options selects the area to scan. It adjust the -l -t -x -y
58 options accordingly. It does not need to be the real size of the
59 paper.
60 -l -t -x -y
63 control the scan area: -l sets the top left x coordinate, -t the
64 top left y coordinate, -x selects the width and -y the height of
65 the scan area. All parameters are specified in millimeters. It
66 is possible to use the option --paper-size instead.
67 Enhancement
70 --brightness
73 controls the brightness of the acquired image. The value varies
74 from 1 to 255, or less, depending on the scanner model.
75 --contrast
77 controls the contrast of the acquired image. Some models do not
78 support that option.
79 --automatic-threshold
81 automatically sets brightness, contrast, white level, gamma,
82 noise reduction and image emphasis. These options are not avail‐
83 able when automatic-threshold is in use.
84 --halftone-pattern
86 option sets the tonal gradation for the halftone mode. Pattern
87 downloading is not implemented by the backend.
88 --autoseparation
90 provides automatic separation of text and images.
91 --white-level
93 option indicate the source of the white base.
94 --noise-reduction
96 reduces the isolated dot noise. This option is not supported by
97 all scanners.
98 --image-emphasis
100 option sets the image emphasis. Some selection are not available
101 on all scanners.
102 --gamma
104 options set the gamma curve. It is only valid for Gray modes,
105 and is not available on all scanners. Gamma downloading is not
106 implemented by the backend.
107
111 The configuration file /etc/sane.d/matsushita.conf supports the device
112 name to use (eg /dev/scanner) and the SCSI option to auto-detect the
113 scanners supported.
114
118 /usr/lib*/sane/libsane-matsushita.a
119 The static library implementing this backend.
120 /usr/lib*/sane/libsane-matsushita.so
122 The shared library implementing this backend (present on systems
123 that support dynamic loading).
124
128 SANE_DEBUG_MATSUSHITA
129 If the library was compiled with debug support enabled, this
130 environment variable controls the debug level for this backend.
131 E.g., a value of 128 requests all debug output to be printed.
132 Smaller levels reduce verbosity.
133
137 Memory in the KV-SS 25
138 The KV-SS 25 has not enough internal memory to scan a whole A4
139 page in duplex mode at high resolution. The frontend will return
140 a memory error in that case. Apparently, the KV-SS 25D has not
141 that problem.
142 Pattern and gamma downloading
144 The scanner, with the proper firmware, can download a halftone
145 pattern and a gamma table. This is not implemented.
146 Sub-areas
148 The scanner can support up to 3 sub-areas on each side to define
149 some more precise enhancement options. This is not implemented.
150 Duplex mode
152 The backend does not support the setting of different options
153 for each side. The scan will occur with the same options
154 (halftone pattern, brightness, image emphasis) for both sides.
155
159 To date, the only frontend capable of using this scanner at full speed
160 is scanadf.
161 A scanadf command line would be:
163 scanadf -d matsushita --output-file scan%04d.pbm --start-count 0
165 --duplex --resolution 300 --feeder-mode="All pages" --paper-size="A4"
166
170 None known.
