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

NAME
     sane-snapscan - SANE backend for AGFA SnapScan flatbed scanners

DESCRIPTION
     The sane-snapscan library implements a SANE (Scanner Access Now Easy) back-
     end 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 /usr/local/share/sane/snapscan/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 cor-
     respond 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
     /usr/local/etc/sane.d/snapscan.conf
	    The backend configuration file (see also  description  of  SANE_CON-
	    FIG_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.  On *NIX  systems,	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 /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  ex-
	    plicitly  specified  directories.	For  example,  setting SANE_CON-
	    FIG_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  envi-
	    ronment variable controls the debug level for this backend.  E.g., a
	    value  of 255 requests all debug output to be printed.  Smaller lev-
	    els reduce verbosity.

BUGS
