sane-gphoto2(2) sane-gphoto2(2) 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 cam- eras supported by gphoto2. THIS IS EXTREMELY ALPHA CODE! USE AT YOUR OWN RISK!! 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 characteris- tics of the camera to be used. Resolutions (high resolu- tion, 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 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 "top- folder=/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 /etc/sane.d/gphoto2.conf The backend configuration file (see also descrip- tion of SANE_CONFIG_DIR below). /usr/lib/sane/libsane-gphoto2.a The static library implementing this backend. /usr/lib/sane/libsane-gphoto2.so The shared library implementing this backend (pre- sent 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 configuration file is searched in two default directories: first, the current working directory (".") and then in /etc/sane.d. If the value of the environment variable ends with the directory sepa- rator 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 "/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. SEE ALSO sane(e) AUTHOR Peter S. Fales The manpage was largeley copied from the dc210 manpage. BUGS Many.
