       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
       /system/resources/sane-backends/1.0.18/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

       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 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

       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‐

	      camera=Kodak DC240
	      # this is a comment

	      The  backend  configuration  file	 (see  also   description   of
	      SANE_CONFIG_DIR below).

	      The static library implementing this backend.

	      The shared library implementing this backend (present on systems
	      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 config‐
	      uration file is searched in two default directories: first,  the
	      current	 working   directory   (".")   and   then   in	 /sys‐
	      tem/resources/sane-backends/1.0.18/etc/sane.d.  If the value  of
	      the environment variable ends with the directory separator char‐
	      acter, 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	 "/system/resources/sane-back‐
	      ends/1.0.18/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.

       Many, no doubt.
