Section: SANE Scanner Access Now Easy (5)
Updated: 11 Jul 2008
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 /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'.
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 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 "topfolder=/"

The manpage was largely copied from the dc210 manpage.
Many, no doubt.
