       sane-dc25 - SANE backend for Kodak DC20/DC25 Digital Cameras


       The  sane-dc25  library  implements  a  SANE  (Scanner Access Now Easy)
       backend that provides access  to  Kodak  DC20  and  DC25  cameras.   At
       present,  only the DC25 has been tested, but since the code is based on
       a DC20 interface program, it is likely to work for that model also.


       The current version of  the  backend  only  allows  one  camera  to  be
       connected.  The device name is always "0".


       The  contents of the dc25.conf specify the serial port and baud rate to
       use.  The baud rate specifies the maximum rate to use while downloading
       pictures.   (The  camera  is  always  initialized using 9600 baud, then
       switches to the higher rate).  On my 90MHz Pentium, I usually  have  no
       problems  downloading  at  115200  baud  as  long  as the system is not
       excessively busy and the "interrupt-unmask flag"  is  set  in  the  IDE
       driver  (hdparm  -u1).   Supported  baud rates are: 9600, 19200, 38400,
       57600, and 115200.

       The dumpinquiry line causes some information about  the  camera  to  be
       printed  to  stderr during startup.  Note:  This is not compatible with
       saned, so make sure you don’t have any dumpinquiry  lines  if  you  are
       using saned (i.e. scanning on a remote machine using a network).

       Empty  lines  and  lines  starting with a hash mark (#) are ignored.  A
       sample configuration file is shown below:

              # this is a comment


              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 debugging support enabled, this
              environment variable controls the debug level for this  backend.
              A  value of 128 requests maximally copious debug output; smaller
              levels reduce verbosity.




       Peter Fales,


       Known bugs/limitations are:

       I haven’t figured out how to  trigger  an  option  reload  following  a
       "scan."   This  causes  problems  when  a  new  picture  is snapped for
       example, the slider that is used to select the picture from the  camera
       may not be updated immediately.

       SANE  should  go   to   the   SANE   Developers   mailing   list   (see  for details).  You must
