.SH NAME
|
|
sane\-canon_lide70 \- SANE backend for the Canon LiDE 70 and 600(F) USB flatbed scanners
|
|
.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 and 600(F)
|
|
flatbed scanners. The film unit of the LiDE 600F is not supported.
|
|
.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.

.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 is 0x2224.
|
|
|
|
.SH BACKEND SPECIFIC OPTIONS
|
|
.B Scan Mode:
|
|
|
|
.TP
|
|
.B \-\-resolution 75|150|300|600|1200 [default 600]
|
|
Sets the resolution of the scanned image in dots per inch. Scanning at 1200 dpi
|
|
is not available on the LiDE 600(F) and it is very slow on the LiDE 70.
|
|
|
|
.TP
|
|
.B \-\-mode Color|Gray|Lineart [default: Color]
|
|
Selects the scan mode. Lineart means fully black and fully white pixels only.
|
|
|
|
.TP
|
|
.B \-\-threshold 0..100 (in steps of 1) [default 75]
|
|
Select minimum-brightness percentage to get a white point, relevant only for Lineart
|
|
|
|
.TP
|
|
.B \-\-non-blocking[=(yes|no)] [inactive]
|
|
This option has not yet been implemented. Scans are captured in a temporary file with a typical size of 100MB.
|
|
|
|
.PP
|
|
.B Geometry:
|
|
.TP
|
|
.B \-l 0..216.069 [default 0]
|
|
Top-left x position of scan area in millimeters.
|
|
.TP
|
|
.B \-t 0..297 [default 0]
|
|
Top-left y position of scan area in millimeters.
|
|
.TP
|
|
.B \-x 0..216.069 [default 80]
|
|
Width of scan-area in millimeters.
|
|
.TP
|
|
.B \-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 LiDE 70 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
|
|
.BR xsane (1)
|
|
uses the 75 dpi mode for prescans. The problem is worse on the LiDE 600(F),
|
|
where the offset is five millimeters.
