## NAME

           sane-snapscan - SANE backend for AGFA SnapScan flatbed scanners

## DESCRIPTION

           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

           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 sane-
           scsi(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

           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 consti-
           tutes a valid device name.

## FILES

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

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

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

## ENVIRONMENT

           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 config-
                  uration file is searched in two default directories: first,  the
                  current     working     directory     (".")    and    then    in
                  /usr/local/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 directo-
                  ries.   For  example,  setting SANE_CONFIG_DIR to "/tmp/config:"
                  would   result   in   directories   "tmp/config",    ".",    and
                  "/usr/local/etc/sane.d" being searched (in this order).

           SANE_DEBUG_SNAPSCAN
                  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.
