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) back- end 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 character 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 connected. 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 frontends, 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 exam- ple, 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 "topfolder=/" 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_CON- FIG_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 directories are separated by a colon (`:'), under OS/2, they are separated 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/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 ex- plicitly specified directories. For example, setting SANE_CON- FIG_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 en- vironment 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.

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 sub- scribers. 11 Jul 2008 sane-gphoto2(5)
