       sane-snapscan - SANE backend for AGFA SnapScan flatbed scanners

DESCRIPTION    [Toc]    [Back]

       The  sane-snapscan  library implements a SANE (Scanner Access Now Easy)
       backend that provides access to	AGFA  SnapScan	flatbed  scanners.  At
       present,  the  following scanners are supported from this backend: AGFA
       SnapScan 300, 310, 600, and 1236s, 1236u, 1212u, e20,  e25,  e40,  e50,
       e60,  Vuego  310s,  Acer  300f,	310s, 610s, 610plus, Prisa 620s, Prisa
       620u, Prisa 620ut, Prisa 640u, Prisa 640bu,  Prisa  1240,  Prisa  3300,
       Prisa  4300,  Prisa 5300 and Guillemot Maxi Scan A4 Deluxe (SCSI) (with
       varying success).

DEVICE NAMES    [Toc]    [Back]

       This backend expects device names of the form:

	      special

       Where special is the path-name for the special device that  corresponds
       to a SCSI scanner. For SCSI scanners, the special device name must be a
       generic SCSI device or a symlink to such a device.  Under Linux, such a
       device  name  could  be	/dev/sga  or /dev/sge, for example.  See sanescsi(5) for details.

       For USB scanners the devicename must contain the keyword "usb",	as  in
       /dev/usbscanner	 or  /dev/usb/scanner0.   For  scanners  that  need  a
       firmware upload before scanning add a  line  starting  with  "firmware"
       followed by the fully qualified path to your firmware file, e.g.

	      firmware /path/to/my/firmware.bin

       For further details read http://snapscan.sourceforge.net.

CONFIGURATION    [Toc]    [Back]

       The  contents  of the snapscan.conf file is a list of device names that
       correspond to SnapScan scanners.  Empty lines and lines starting with a
       hash mark (#) are ignored.  See sane-scsi(5) on details of what constitutes
 a valid device name.

FILES    [Toc]    [Back]

       /etc/sane.d/snapscan.conf
	      The  backend  configuration  file  (see  also   description   of
	      SANE_CONFIG_DIR below).

       /usr/lib/sane/libsane-snapscan.a
	      The static library implementing this backend.

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

ENVIRONMENT    [Toc]    [Back]

       SANE_CONFIG_DIR
	      This environment variable specifies the list of directories that
	      may contain the configuration file.  Under UNIX, the directories
	      are separated by a colon (`:'), under OS/2, they	are  separated
	      by a semi-colon (`;').  If this variable is not set, the configuration
 file is searched in two default directories: first,  the
	      current working directory (".") and then in /etc/sane.d.	If the
	      value of the environment variable ends with the directory  separator
 character, then the default directories are searched after
	      the explicitly  specified  directories.	For  example,  setting
	      SANE_CONFIG_DIR  to  "/tmp/config:"  would result in directories
	      "tmp/config", ".", and "/etc/sane.d"  being  searched  (in  this
	      order).

       SANE_DEBUG_SNAPSCAN    [Toc]    [Back]
	      If  the  library	was  compiled with debug support enabled, this
	      environment variable controls the debug level for this  backend.
	      E.g.,  a	value  of 255 requests all debug output to be printed.
	      Smaller levels reduce verbosity.
