sane-dc25(5) SANE Scanner Access Now Easy sane-dc25(5)
NAME
sane-dc25 - SANE backend for Kodak DC20/DC25 Digital Cameras
DESCRIPTION
The sane-dc25 library implements a SANE (Scanner Access Now Easy) back-
end that provides access to Kodak DC20 and DC25 cameras. At present,
only the DC25 has been tested, but since the code is based on a DC20 in-
terface program, it is likely to work for that model also.
DEVICE NAMES
The current version of the backend only allows one camera to be con-
nected. The device name is always "0".
CONFIGURATION
The contents of the dc25.conf specify the serial port and baud rate to
use. The baud rate specifies the maximum rate to use while downloading
pictures. (The camera is always initialized using 9600 baud, then
switches to the higher rate). On my 90MHz Pentium, I usually have no
problems downloading at 115200 baud as long as the system is not exces-
sively busy and the "interrupt-unmask flag" is set in the IDE driver
(hdparm -u1). Supported baud rates are: 9600, 19200, 38400, 57600, and
115200.
The dumpinquiry line causes some information about the camera to be
printed to stderr during startup. Note: This is not compatible with
saned, so make sure you don't have any dumpinquiry lines if you are us-
ing saned (i.e. scanning on a remote machine using a network).
Empty lines and lines starting with a hash mark (#) are ignored. A sam-
ple configuration file is shown below:
port=/dev/ttyS0

FILES
/etc/sane.d/dc25.conf
The backend configuration file (see also description of SANE_CON-
FIG_DIR below).
/usr/lib/x86_64-linux-gnu/sane/libsane-dc25.a
The static library implementing this backend.
/usr/lib/x86_64-linux-gnu/sane/libsane-dc25.so
The shared library implementing this backend (present on systems
that support dynamic loading).
ENVIRONMENT
SANE_CONFIG_DIR
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 sepa-
rated 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 /etc/sane.d. 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
SANE_CONFIG_DIR to "/tmp/config:" would result in directories
tmp/config, ., and /etc/sane.d being searched (in this order).
SANE_DEBUG_DC25
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.

BUGS
Known bugs/limitations are:
I haven't figured out how to trigger an option reload following a
"scan." This causes problems when a new picture is snapped for example,
the slider that is used to select the picture from the camera may not be
updated immediately.
More general comments, suggestions, and inquiries about frontends or
SANE should go to the SANE Developers mailing list (see
http://www.sane-project.org/mailing-lists.html for details). You must
be subscribed to the list, otherwise your mail won't be sent to the sub-
scribers.
