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 scan­
       ners  are  supported from this backend: AGFA SnapScan 300,
       310, 600, and 1236s, 1212u, e40,  e50,  Vuego  310s,  Acer
       300f,  310s,  610s, 610plus, Prisa 620s, Prisa 620u, Prisa
       640u, Prisa 640bu, Guillemot Maxi Scan  A4  Deluxe  (SCSI)
       (with varying success).


DEVICE NAMES

       This backend expects device names of the form:

              special

       Where  special  is  either  the  path-name for the special
       device that corresponds to a SCSI scanner. For SCSI  scan­
       ners,  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 see http://snapscan.sourceforge.net/  for
       details.


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 constitutes a valid device
       name.


FILES

       /etc/sane.d/snapscan.conf
              The  backend  configuration file (see also descrip­
              tion 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  (pre­
              sent on systems that support dynamic loading).


ENVIRONMENT


              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 sepa­
              rator 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 "/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.
