NAME

       sane-gphoto2 - SANE backend for gphoto2 supported cameras

DESCRIPTION

       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.

DEVICE NAMES

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

CONFIGURATION

       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  fron-
       tends,  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
       printed.

       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-
       folder=/"

              port=usb:
              camera=Kodak DC240
              # this is a comment
              high_resolution=1280x960
              low_resolution=640x480
              thumb_resolution=160x120
              dumpinquiry

FILES

       /usr/local/etc/sane.d/gphoto2.conf
              The   backend   configuration  file  (see  also  description  of
              SANE_CONFIG_DIR below).

       /usr/local/lib/sane/libsane-gphoto2.a
              The static library implementing this backend.

       /usr/local/lib/sane/libsane-gphoto2.so
              The shared library implementing this backend (present on systems
              that support dynamic loading).

ENVIRONMENT

       SANE_CONFIG_DIR
              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).

       SANE_DEBUG_GPHOTO2
              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.

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