.SH NAME
|
|
sane\-gphoto2 \- SANE backend for gphoto2 supported cameras
|
|
.SH DESCRIPTION
|
|
The
|
|
.B 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.
|
|
.PP
|
|
Because of the limited testing of this backend, it is commented out
|
|
in @CONFIGDIR@/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'.
|
|
.SH "DEVICE NAMES"
|
|
The current version of the backend only allows one camera to be
|
|
connected. The device name is always "0".
|
|
.SH CONFIGURATION
|
|
The contents of the
|
|
.I 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".
|
|
.PP
|
|
The dumpinquiry line causes some information about the camera to
|
|
be printed.
|
|
.PP
|
|
Empty lines and lines starting with a hash mark (#) are
|
|
ignored. A sample configuration file is shown below:
|
|
.PP
|
|
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"
|
|
.PP
|
|
Some cameras don't implement a file structure and store all pictures
|
|
in the "/" directory. This is indicated by setting "subdirs=0" with
|
|
"topfolder=/"

.SH FILES
|
|
.TP
|
|
.I @CONFIGDIR@/gphoto2.conf
|
|
The backend configuration file (see also description of
|
|
.B SANE_CONFIG_DIR
|
|
below).
|
|
.TP
|
|
.I @LIBDIR@/libsane\-gphoto2.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane\-gphoto2.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B 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 configuration file
|
|
is searched in two default directories: first, the current working
|
|
directory (".") and then in @CONFIGDIR@. 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
|
|
.B SANE_CONFIG_DIR
|
|
to "/tmp/config:" would result in directories "tmp/config", ".", and
|
|
"@CONFIGDIR@" being searched (in this order).
|
|
.TP
|
|
.B 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.
|
|
.TP
|
|
.B GP_DEBUG
|
|
Set to 1, 2, or 3, to enable various levels of debugging within the
|
|
gphoto2 libraries.

The manpage was largely copied from the dc210 manpage.
