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 IS EXTREMELY ALPHA CODE! USE AT
YOUR OWN RISK!!
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 --list-
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 con-
stant, but 100DC240 will change and must be read from the camers. 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=/"

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 vari-
able controls the debug level for this backend. A value of 128 requests maximally
copious debug output; smaller levels reduce verbosity.
