sane-gphoto2(5)		 SANE Scanner Access Now Easy	       sane-gphoto2(5)

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	front-
       ends, 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.  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/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/lo-
	      cal/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.

BUGS
       Many, no	doubt.

       More general comments, suggestions, and inquiries  about	 frontends  or
       SANE   should   go   to	 the   SANE   Developers   mailing  list  (see
       http://www.sane-project.org/mailing-lists.html for details).  You  must
       be  subscribed  to  the	list, otherwise	your mail won't	be sent	to the
       subscribers.
