       sane-abaton - SANE backend for Abaton flatbed scanners


       The  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.

       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
       with the model number, so that arrangements  can  be  made  to  include
       support        for        it.        Have        a        look       at concerning  subscription
       to sane-devel.

       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.

       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.


       This backend expects device names of the form:


       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 takes a format such as /dev/sga or /dev/sg0,  for  example.
       See sane-scsi(5) for details.


       The  contents  of  the  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.


              The  backend  configuration  file  (see  also   description   of
              SANE_CONFIG_DIR below).

              The static library implementing this backend.

              The shared library implementing this backend (present on systems
              that support dynamic loading).


              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 separator character, then the default directories
              are searched after the explicitly  specified  directories.   For
              example,  setting SANE_CONFIG_DIR to "/tmp/config:" would result
              in  directories  "tmp/config",  ".",  and  "/etc/sane.d"   being
              searched (in this order).

              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.


       There are a few known ones, and definitely some unknown ones.

       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.

       Cancelling the scan
              This might not work correctly, or it might abort  the  frontend.
              The former is more likely than the latter.

       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


       Implement non-blocking support

       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.

       The sane-abaton backend was partially written by David  Huggins-Daines,
       based on the sane-apple backend by Milon Firikis.
