.SH NAME
sane-snapscan - SANE backend for AGFA SnapScan flatbed scanners
.SH DESCRIPTION
The
.B 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,
310s, 600, and 1236s, and close compatibles like the Vuego 310s (with
varying success).
.PP
.SH "DEVICE NAMES"
This backend expects device names of the form:
.PP
.RS
.I special
.RE
.PP
Where
.I special
is either 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
.I /dev/sga
or
.IR /dev/sge ,
for example. See sane-scsi(5) for details.
.SH CONFIGURATION
The contents of the
.I 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.
.SH FILES
.TP
.I @CONFIGDIR@/snapscan.conf
The backend configuration file (see also description of
.B SANE_CONFIG_DIR
below).
.TP
.I @LIBDIR@/libsane-snapscan.a
The static library implementing this backend.
.TP
.I @LIBDIR@/libsane-snapscan.so
The shared library implementing this backend (present on systems that
support dynamic loading).
.SH ENVIRONMENT
.TP
.B 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 @CONFIGDIR@. 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
.B SANE_CONFIG_DIR
to "/tmp/config:" would result in directories "tmp/config", ".", and
"@CONFIGDIR@" being searched (in this order).
.TP
.B 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.
