sane-canon(5)						   SANE Scanner Access Now Easy 					     sane-canon(5)

NAME

       sane-canon - SANE backend for Canon SCSI scanners

DESCRIPTION

       The  sane-canon	library  implements  a SANE (Scanner Access Now Easy) backend that provides access to the following Canon flatbed and film
       scanners:

	      CanoScan 300
	      CanoScan 600
	      CanoScan FB620S
	      CanoScan FB1200S
	      CanoScan FS2700F
	      CanoScan FS2710S

       Parallel port and USB scanners are not supported by this backend; see the manual pages for sane-canon_pp  and  sane-canon630u  for  further
       information.

       IMPORTANT:  This  is beta code. We tested the code on the scanners listed above, using the computers and operating systems available to us,
       but we cannot guarantee that the backend will work smoothly with future operating systems, SCSI adapters, SANE frontend programs, or  Canon
       scanners  not  contained  in  the  list above. In some cases your computer might even hang.  It cannot be excluded (although we consider it
       extremely unlikely) that your scanner will be damaged.

       That said, TESTERS ARE WELCOME. Send your bug reports and comments to Manuel Panea <mpd@rzg.mpg.de>; for questions concerning the FB620 and
       FB1200S contact Mitsuru Okaniwa <m-okaniwa@bea.hi-ho.ne.jp>, for the FS2710S Ulrich Deiters <ukd@xenon.pc.uni-koeln.de>.

TIPS (FS2700F)
       Scanning  either  slides  or  negatives	has  been found to require rather large gamma corrections of about 2.2 to 2.4 (same value for red,
       green, and blue). It is recommended to use the automatic exposure controls of the frontend xsane for best results.

       The "Auto Focus" function triggers a special pass to determine the focus value. After that, the real scanning pass takes place.

       Even with "Auto Focus" turned on, the scanned image is often a bit too blurred. Using the GIMP to do a "Filter->Enhance->Sharpen" at  about
       40 to 60 improves the image considerably.

TIPS (FS2710S)
       Gamma  corrections  are	done  not by the scanner, but by the backend.  The scanner is always run in 12-bit mode. In "color" mode the image
       data are corrected for gamma, shadow point, etc., and then truncated to 8-bit intensities; the default gamma value is 2.0.  In  "raw"  mode
       the  image  data  are  exported without corrections as 16-bit intensities; this mode can be recommended if extensive adjustments have to be
       made to a picture (and if the frontend can handle 16-bit intensities).

       Negatives are handled by simple color inversion and may require manual removal of blue discoloration.

FILES

       /usr/lib64/sane/libsane-canon.a
	      The static library implementing this backend.

       /usr/lib64/sane/libsane-canon.so
	      The shared library implementing this backend (present on systems that support dynamic loading).

ENVIRONMENT

       SANE_DEBUG_CANON
	      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: export SANE_DEBUG_CANON=4

NAME

       sane-mustek_usb2 - SANE backend for SQ113 based USB flatbed scanners

DESCRIPTION

       The  sane-mustek_usb2 library implements a SANE (Scanner Access Now Easy) backend that provides access to USB flatbed scanners based on the
       Service & Quality SQ113 chipset. At the moment, only the Mustek BearPaw 2448 TA Pro is supported. It's planned to  add  support	for  other
       scanners   that	 are   based   on   the   SQ113   and	maybe  SQ11  chip.  For  more  details,  see  the  mustek_usb2	backend  homepage:
       http://www.meier-geinitz.de/sane/mustek_usb2-backend/.

       This is BETA software. Especially if you test new or untested scanners, keep your hand at the scanner's plug and unplug	it,  if  the  head
       bumps at the end of the scan area.

       If  you own a scanner other than the ones listed on the mustek_usb2 homepage that works with this backend, please let me know this by send-
       ing the scanner's exact model name and the USB vendor and device ids (e.g. from sane-find-scanner or syslog) to me. Even if  the  scanner's
       name is only slightly different from the models already listed as supported, please let me know.

LIBUSB ISSUES

       Please  use libusb-0.1.8 or later. Without libusb or with older libusb versions all kinds of trouble can be expected. The scanner should be
       found by sane-find-scanner without further actions. For setting permissions and general USB information looks at sane-usb(5).

FILES

       /usr/lib64/sane/libsane-mustek_usb2.a
	      The static library implementing this backend.

       /usr/lib64/sane/libsane-mustek_usb2.so
	      The shared library implementing this backend (present on systems that support dynamic loading).

ENVIRONMENT

       SANE_DEBUG_MUSTEK_USB2
	      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: export SANE_DEBUG_MUSTEK_USB2=4

BUGS

       Please  contact me if you find a bug or missing feature: <henning@meier-geinitz.de>. Please send a debug log if your scanner isn't detected
       correctly (see SANE_DEBUG_MUSTEK_USB2 above).
