6 sane-gphoto2 - SANE backend for gphoto2 supported cameras
7
9 The sane-gphoto2 library implements a SANE (Scanner Access Now Easy)
10 backend that provides access to the digital cameras supported by
11 gphoto2. This backend has only been tested with a handful of cameras
12 so far. Patches to support other models are welcome.
13 Because of the limited testing of this backend, it is commented out in
15 /etc/sane.d/dll.conf by default. Either the comment character must be
16 removed or the backend must be called explicitly. E.g. scanimage -d
17 gphoto2 or xscanimage gphoto2.
18
20 The current version of the backend only allows one camera to be con‐
21 nected. The device name is always "0".
22
24 The contents of the gphoto2.conf specify the characteristics of the
25 camera to be used. Resolutions (high resolution, low resolution, and
26 thumbnail size) are required since they are needed by the sane front‐
27 ends, but can't be obtained through the gphoto2 interface. Valid ports
28 and cameras can be obtained by gphoto2 --list-cameras and gphoto2
29 --list-ports .
30 The dumpinquiry line causes some information about the camera to be
32 printed.
33 Empty lines and lines starting with a hash mark (#) are ignored. A
35 sample configuration file is shown below:
36 The topfolder line specifies the "fixed" part of the file path. For
38 example, on the Kodak DC-240, files are stored in the directory
39 /DCIM/100DC240. The /DCIM portion is constant, but 100DC240 will
40 change and must be read from the camera. In this case, the line would
41 read "topfolder=/DCIM"
42 Some cameras don't implement a file structure and store all pictures in
44 the / directory. This is indicated by setting "subdirs=0" with "top‐
45 folder=/"

56 /etc/sane.d/gphoto2.conf
57 The backend configuration file (see also description of
58 SANE_CONFIG_DIR below).
59 /usr/lib64/sane/libsane-gphoto2.a
61 The static library implementing this backend.
62 /usr/lib64/sane/libsane-gphoto2.so
64 The shared library implementing this backend (present on systems
65 that support dynamic loading).

69 SANE_CONFIG_DIR
70 This environment variable specifies the list of directories that
71 may contain the configuration file. On *NIX systems, the direc‐
72 tories are separated by a colon (`:'), under OS/2, they are sep‐
73 arated by a semi-colon (`;'). If this variable is not set, the
74 configuration file is searched in two default directories:
75 first, the current working directory (.) and then in
76 /etc/sane.d. If the value of the environment variable ends with
77 the directory separator character, then the default directories
78 are searched after the explicitly specified directories. For
79 example, setting SANE_CONFIG_DIR to "/tmp/config:" would result
80 in directories tmp/config, ., and /etc/sane.d being searched (in
81 this order).
82 SANE_DEBUG_GPHOTO2
84 If the library was compiled with debugging support enabled, this
85 environment variable controls the debug level for this backend.
86 A value of 128 requests maximally copious debug output; smaller
87 levels reduce verbosity.
88 GP_DEBUG
90 Set to 1, 2, or 3, to enable various levels of debugging within
91 the gphoto2 libraries.
