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. +.PP +TESTERS ARE WELCOME. Send your bug reports and comments to +the sane\-devel mailing list +.PP +The +.B Canoscan LiDE 600 +(or 600f, with film unit) is closely related to the LiDE 70, but +it does not work with this backend. Support for the LiDE 600 will +be added by the end of 2020. +.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. +.PP +.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. +.PP +.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 1.5 +to get more realistic colors. This also wipes out some artifacts caused by +the lack of real calibration. +.SH "SEE ALSO" +sane(7), sane\-usb(5), sane\-find\-scanner(1), scanimage(1) +.br +http://www.juergen-ernst.de/info_sane.html +.br +.SH AUTHOR +pimvantend, building upon pioneering work by Juergen Ernst. -- cgit v1.2.3
