NAME
sane-dc25 - SANE backend for Kodak DC20/DC25 Digital Cameras
DESCRIPTION
The sane-dc25 library implements a SANE (Scanner Access Now Easy) backend
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 interface
program, it is likely to work for that model also.
DEVICE NAMES
The current version of the backend only allows one camera to be
connected. 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
excessively 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 using
saned (i.e. scanning on a remote machine using a network).
Empty lines and lines starting with a hash mark (#) are ignored. A
sample configuration file is shown below:
port=/dev/ttyS0

FILES
/opt/local/etc/sane.d/dc25.conf
The backend configuration file (see also description of
SANE_CONFIG_DIR below).
/opt/local/lib/sane/libsane-dc25.a
The static library implementing this backend.
/opt/local/lib/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
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
/opt/local/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
/opt/local/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
subscribers.
