sane-gphoto2 - SANE backend for gphoto2 supported cameras


   The  sane-gphoto2  library  implements a SANE (Scanner Access Now Easy)
   backend that provides  access  to  the  digital  cameras  supported  by
   gphoto2.   This  backend has only been tested with a handful of cameras
   so far.  Patches to support other models are welcome.

   Because of the limited testing of this backend, it is commented out  in
   /etc/sane.d/dll.conf  by default.  Either the comment character must be
   removed or the backend must be called explicitly.  E.g.  `scanimage  -d
   gphoto2' or `xscanimage gphoto2'.


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


   The contents of the gphoto2.conf specify  the  characteristics  of  the
   camera  to be used.   Resolutions (high resolution, low resolution, and
   thumbnail size)  are  required  since  they  are  needed  by  the  sane
   frontends,  but can't be obtained through the gphoto2 interface.  Valid
   ports and cameras can  be  obtained  by  "gphoto2  --list-cameras"  and
   "gphoto2 --list-ports".

   The  dumpinquiry  line  causes  some information about the camera to be

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

   The  "topfolder" line specifies the "fixed" part of the file path.  For
   example, on the  Kodak  DC-240,  files  are  stored  in  the  directory
   /DCIM/100DC240.   The  /DCIM  portion  is  constant,  but 100DC240 will
   change and must be read from the camera.  In this case, the line  would
   read "topfolder=/DCIM"

   Some cameras don't implement a file structure and store all pictures in
   the "/" directory.  This  is  indicated  by  setting  "subdirs=0"  with

          camera=Kodak DC240
          # this is a comment

          SANE_CONFIG_DIR below).

          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.

          Set  to 1, 2, or 3, to enable various levels of debugging within
          the gphoto2 libraries.
