.SH NAME
|
|
sane-abaton - SANE backend for Abaton flatbed scanners
|
|
.SH DESCRIPTION
|
|
The
|
|
.B sane-abaton
|
|
library implements a SANE (Scanner Access Now Easy) backend that
|
|
provides access to Abaton flatbed scanners. At present, only the Scan
|
|
300/GS (8bit, 256 levels of gray) is fully supported, due to the
|
|
absence of programming information. The Scan 300/S (black and white)
|
|
is recognized, but support for it is untested.
|
|
.PP
|
|
If you own a Abaton scanner other than the ones listed above that
|
|
works with this backend, or if you own an Abaton scanner that does not
|
|
work with this backend, please contact
|
|
.IR sane\-devel@mostang.com
|
|
with the model number, so that arrangements can be made to include
|
|
support for it.
|
|
.PP
|
|
Abaton is out of business, and these scanners are not supported by
|
|
Everex (the parent company of Abaton), nor is there any programming
|
|
information to be found. This driver is therefore based on
|
|
information obtained by running Abaton's scanning desk accessory under
|
|
MacsBug and tracing the MacOS SCSI Manager calls it made during image
|
|
acquisition.
|
|
.PP
|
|
However, the protocol is very similar to, though not compatible with,
|
|
the one used by the Apple scanners, therefore, if this backend is ever
|
|
extended to support the other Abaton models (they also made a color
|
|
flatbed scanner), it may be possible to fill in some "missing pieces"
|
|
from the (quite detailed) Apple scanner documentation.
|
|
|
|
.SH "DEVICE NAMES"
|
|
This backend expects device names of the form:
|
|
.PP
|
|
.RS
|
|
.I special
|
|
.RE
|
|
.PP
|
|
Where
|
|
.I 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 takes a format such as
|
|
.I /dev/sga
|
|
or
|
|
.IR /dev/sg0 ,
|
|
for example. See sane-scsi(5) for details.
|
|
.SH CONFIGURATION
|
|
The contents of the
|
|
.I abaton.conf
|
|
file is a list of device names that correspond to Abaton 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@/abaton.conf
|
|
The backend configuration file (see also description of
|
|
.B SANE_CONFIG_DIR
|
|
below).
|
|
.TP
|
|
.I @LIBDIR@/libsane-abaton.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane-abaton.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_ABATON
|
|
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.
|
|
|
|
.SH BUGS
|
|
There are a few known ones, and definitely some unknown ones.
|
|
.TP
|
|
.B Scan area miscalculations
|
|
For the sake of programmer efficiency, this backend handles all
|
|
measurements in millimetres, and floors (rather than rounds) values to
|
|
avoid possible damage to the scanner mechanism. Therefore, it may not
|
|
be possible to scan to the extreme right or bottom edges of the page.
|
|
.TP
|
|
.B Cancelling the scan
|
|
This might not work correctly, or it might abort the frontend. The
|
|
former is more likely than the latter.
|
|
.PP
|
|
If you have found something that you think is a bug, please attempt to
|
|
recreate it with the SANE_DEBUG_ABATON environment variable set to
|
|
255, and send a report detailing the conditions surrounding the bug to
|
|
.IR sane\-devel@mostang.com .
|
|
|
|
.SH TODO
|
|
.TP
|
|
.B Implement non-blocking support
|
|
.TP
|
|
.B Finish reverse-engineering the MacOS driver
|
|
This will allow me to add support for other models with reasonable
|
|
confidence that it will work, as well as to fully exploit the
|
|
information returned by the INQUIRY command.
