.SH NAME
|
||
|
sane\-canon_lide70 \- SANE backend for the Canon LiDE 70 USB flatbed scanner
|
||
|
.SH DESCRIPTION
|
||
|
The
|
||
|
.B canon_lide70
|
||
|
library implements a SANE (Scanner Access Now Easy) backend that
|
||
|
provides access to the Canon Inc. CanoScan LiDE 70 flatbed scanner.
|
||
|
.PP
|
||
|
Due to Canon's unwillingness to provide scanner documentation, this
|
||
|
software was developed by analyzing the USB traffic of the Windows
|
||
|
XP driver. The precise meaning of the individual commands that are sent
|
||
|
to the scanner is known only to a very limited extent. Some sophistication
|
||
|
present in the Windows XP driver has been left out. There is, for example,
|
||
|
no active calibration.
|
||
|

|
||
|
TESTERS ARE WELCOME. Send your bug reports and comments to
|
||
|
the sane\-devel mailing list <sane\-devel@alioth-lists.debian.net>
|
||
|
.PP
|
||
|
The
|
||
|
.B Canoscan LiDE 600
|
||
|
(or 600f, with film unit) is closely related to the LiDE 70, but
|
||
|
it probably will not work with this backend. The framework of this canon_lide70
|
||
|
backend could likely be used to develop a backend for the LiDE 600 without too
|
||
|
much difficulty.
|
||
|
.PP
|
||
|
.SH CONFIGURATION
|
||
|
The
|
||
|
.I @CONFIGDIR@/canon_lide70.conf
|
||
|
file identifies the LiDE 70 by its vendor code 0x04a9 and its
|
||
|
product code 0x2225. For the LiDE 600(f) the product code would be 0x2224.

.SH BACKEND SPECIFIC OPTIONS
|
||
|
.PP
|
||
|
.B Scan Mode:
|
||
|
.TP
|
||
|
\-\-resolution 75|150|300|600|1200 [default 600]
|
||
|
.BR
|
||
|
Sets the resolution of the scanned image in dots per inch. Scanning at 1200 dpi is very slow.
|
||
|
.TP
|
||
|
\-\-mode Color|Gray|Lineart [default: Color]
|
||
|
.BR
|
||
|
Selects the scan mode. Lineart means fully black and fully white pixels only.
|
||
|
.TP
|
||
|
\-\-threshold 0..100 (in steps of 1) [default 75]
|
||
|
.BR
|
||
|
Select minimum-brightness percentage to get a white point, relevant only for Lineart
|
||
|
.TP
|
||
|
\-\-non-blocking[=(yes|no)] [inactive]
|
||
|
.BR
|
||
|
This option has not yet been implemented. Scans are captured in a temporary file with a typical size of 100MB.
|
||
|
.PP
|
||
|
.B Geometry:
|
||
|
.TP
|
||
|
\-l 0..216.069 [default 0]
|
||
|
Top-left x position of scan area in millimeters.
|
||
|
.TP
|
||
|
\-t 0..297 [default 0]
|
||
|
Top-left y position of scan area in millimeters.
|
||
|
.TP
|
||
|
\-x 0..216.069 [default 80]
|
||
|
Width of scan-area in millimeters.
|
||
|
.TP
|
||
|
\-y 0..297 [default 100]
|
||
|
Height of scan-area in millimeters.

.SH FILES
|
||
|
.TP
|
||
|
.I @CONFIGDIR@/canon_lide70.conf
|
||
|
The backend configuration file
|
||
|
.TP
|
||
|
.I @LIBDIR@/libsane\-canon_lide70.a
|
||
|
The static library implementing this backend.
|
||
|
.TP
|
||
|
.I @LIBDIR@/libsane\-canon_lide70.so
|
||
|
The shared library implementing this backend (present on systems that
|
||
|
support dynamic loading).
|
||
|
.SH ENVIRONMENT
|
||
|
.TP
|
||
|
.B SANE_DEBUG_CANON_LIDE70
|
||
|
If the library was compiled with debug support enabled, this
|
||
|
environment variable controls the debug level for this backend. Higher
|
||
|
debug levels increase the verbosity of the output.
|
||
|
|
||
|
Example:
|
||
|
.br
|
||
|
SANE_DEBUG_CANON_LIDE70=128 scanimage > /dev/null
|
||
|
.SH KNOWN PROBLEMS
|
||
|
At low resolutions (75 and 150 dpi, implying high slider speeds)
|
||
|
the scanner misses the top one millimeter of the scan area. This can
|
||
|
be remedied by shifting the document one millimeter downward, in cases
|
||
|
where such precision matters. Note that xsane uses the 75 dpi mode for
|
||
|
prescans.
|
||
|
.PP
|
||
|
It is recommended that in xsane the gamma value be set to approximately 2.0
|
||
|
to get more realistic colors. This also wipes out some artifacts caused by
|
||
|
the lack of real calibration.
