       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
       /usr/local/etc/sane.d/dll.conf  by default.  Either the comment charac-
       ter 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 con-
       nected.  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  front-
       ends, but can't be obtained through the gphoto2 interface.  Valid ports
       and cameras can be  obtained  by  gphoto2  --list-cameras  and  gphoto2

       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  "top-

              SANE_CONFIG_DIR below).

              This environment variable specifies the list of directories that
              may contain the configuration file.  On *NIX systems, the direc-
              tories are separated by a colon (`:'), under OS/2, they are sep-
              arated 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  /usr/lo-
              cal/etc/sane.d.   If  the value of the environment variable ends
              with the directory separator character, then the default  direc-
              tories  are searched after the explicitly specified directories.
              For example, setting SANE_CONFIG_DIR to "/tmp/config:" would re-
              sult in directories tmp/config, ., and /usr/local/etc/sane.d be-
              ing 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.
