NAME

6       sane-gphoto2 - SANE backend for gphoto2 supported cameras
7

DESCRIPTION

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
14       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

DEVICE NAMES

20       The  current  version  of the backend only allows one camera to be con‐
21       nected.  The device name is always "0".
22

CONFIGURATION

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  fron‐
27       tends,  but  can't  be  obtained  through the gphoto2 interface.  Valid
28       ports and cameras can  be  obtained  by  "gphoto2  --list-cameras"  and
29       "gphoto2 --list-ports".
30
31       The  dumpinquiry  line  causes  some information about the camera to be
32       printed.
33
34       Empty lines and lines starting with a hash mark  (#)  are  ignored.   A
35       sample configuration file is shown below:
36
37       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
43       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=/"

FILES

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

ENVIRONMENT

69       SANE_CONFIG_DIR
70              This environment variable specifies the list of directories that
71              may contain the configuration file.  Under UNIX, the directories
72              are  separated  by a colon (`:'), under OS/2, they are separated
73              by a semi-colon (`;').  If this variable is not set, the config‐
74              uration  file is searched in two default directories: first, the
75              current working directory (".") and then in /etc/sane.d.  If the
76              value  of the environment variable ends with the directory sepa‐
77              rator character, then the default directories are searched after
78              the  explicitly  specified  directories.   For  example, setting
79              SANE_CONFIG_DIR to "/tmp/config:" would  result  in  directories
80              "tmp/config",  ".",  and  "/etc/sane.d"  being searched (in this
81              order).
82
83       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
89       GP_DEBUG
90              Set  to 1, 2, or 3, to enable various levels of debugging within
91              the gphoto2 libraries.
