sane-dc25 - SANE backend for Kodak DC20/DC25 Digital Cameras
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.
The current version of the backend only allows one camera to be connected. The device name is always "0".
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

/etc/sane.d/dc25.conf
The backend configuration file (see also description of
SANE_CONFIG_DIR below).
/usr/lib/arch_triplet/sane/libsane-dc25.a
The static library implementing this backend.
/usr/lib/arch_triplet/sane/libsane-dc25.so
The shared library implementing this backend (present on systems
that support dynamic loading).
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
/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.

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.
