sane-gphoto2 - SANE backend for gphoto2 supported cameras
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
/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
The current version of the backend only allows one camera to be connected. 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 frontends, but can't be
obtained through the gphoto2 interface. Valid ports and cameras can be
obtained by "gphoto2 --list-cameras" and "gphoto2
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
Some cameras don't implement a file structure and store all pictures in the
"/" directory. This is indicated by setting "subdirs=0"

- 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 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 separator character, 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
"/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
- Set to 1, 2, or 3, to enable various levels of debugging
within the gphoto2 libraries.

Many, no doubt.
