sane-gphoto2(5) SANE Scanner Access Now Easy sane-gphoto2(5)NAMEsane-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
/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
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 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=/"

FILES
/system/resources/sane-backends/1.0.18/etc/sane.d/gphoto2.conf
The backend configuration file (see also description of
SANE_CONFIG_DIR below).
/system/resources/sane-backends/1.0.18/lib/sane/libsane-gphoto2.a
The static library implementing this backend.
/system/resources/sane-backends/1.0.18/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 /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).
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.

SANE should go to the SANE Developers mailing list (see
