## 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 camers.  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.  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 config-
                  uration  file is searched in two default directories: first, the
                  current    working    directory    (".")     and     then     in
                  /usr/local/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 directo-
                  ries.  For example, setting  SANE_CONFIG_DIR  to  "/tmp/config:"
                  would    result    in   directories   "tmp/config",   ".",   and
                  "/usr/local/etc/sane.d" being 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.
