<H2>NAME</H2><PRE>
sane-gphoto2 - SANE backend for gphoto2 supported cameras
</PRE>
<H2>DESCRIPTION</H2><PRE>
The <B>sane-gphoto2</B> 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
<I>/usr/local/etc/sane.d/dll.conf</I> by default. Either the comment charac-
ter must be removed or the backend must be called explicitly. E.g.
<I>scanimage</I> <I>-d</I> <I>gphoto2</I> or <I>xscanimage</I> <I>gphoto2</I>.
</PRE>
<H2>DEVICE NAMES</H2><PRE>
The current version of the backend only allows one camera to be con-
nected. The device name is always "0".
</PRE>
<H2>CONFIGURATION</H2><PRE>
The contents of the <I>gphoto2.conf</I> 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 front-
ends, but can't be obtained through the gphoto2 interface. Valid ports
and cameras can be obtained by <I>gphoto2</I> <I>--list-cameras</I> and <I>gphoto2</I>
<I>--list-ports</I>.
The <B>dumpinquiry</B> 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 <B>topfolder</B> line specifies the "fixed" part of the file path. For
example, on the Kodak DC-240, files are stored in the directory
<I>/DCIM/100DC240.</I> The <I>/DCIM</I> 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 <I>/</I> directory. This is indicated by setting "subdirs=0" with "top-
folder=/"
port=usb:
camera=Kodak DC240

</PRE>
<H2>FILES</H2><PRE>
<I>/usr/local/etc/sane.d/gphoto2.conf</I>
The backend configuration file (see also description of
<B>SANE_CONFIG_DIR</B> below).
<I>/usr/local/lib/sane/libsane-gphoto2.a</I>
The static library implementing this backend.
<I>/usr/local/lib/sane/libsane-gphoto2.so</I>
The shared library implementing this backend (present on systems
that support dynamic loading).
</PRE>
<H2>ENVIRONMENT</H2><PRE>
<B>SANE_CONFIG_DIR</B>
This environment variable specifies the list of directories that
may contain the configuration file. On *NIX systems, the direc-
tories are separated by a colon (`:'), under OS/2, they are sep-
arated by a semi-colon (`;'). If this variable is not set, the
configuration file is searched in two default directories:
first, the current working directory (<I>.</I>) and then in <I>/usr/lo-</I>
<I>cal/etc/sane.d</I>. If the value of the environment variable ends
with the directory separator character, then the default direc-
tories are searched after the explicitly specified directories.
For example, setting <B>SANE_CONFIG_DIR</B> to "/tmp/config:" would re-
sult in directories <I>tmp/config</I>, <I>.</I>, and <I>/usr/local/etc/sane.d</I> be-
ing searched (in this order).
<B>SANE_DEBUG_GPHOTO2</B>
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.
<B>GP_DEBUG</B>
Set to 1, 2, or 3, to enable various levels of debugging within
the gphoto2 libraries.

Many, no doubt.
More general comments, suggestions, and inquiries about frontends or
SANE should go to the SANE Developers mailing list (see
