sane-dc25 - SANE backend for Kodak DC20/DC25 Digital Cameras
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
interface program, it is likely to work for that model also.
The current version of the backend only allows one camera to be con-
nected. 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 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
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
sample configuration file is shown below:

The static library implementing this backend.
The shared library implementing this backend (present on systems
that support dynamic loading).
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 config-
uration file is searched in two default directories: first, the
current working directory (".") and then in /usr/lo-
cal/etc/sane.d. If the value of the environment variable ends
with the directory separator character, then the default direc-
tories are searched after the explicitly specified directories.
For example, setting SANE_CONFIG_DIR to "/tmp/config:" would re-
sult in directories tmp/config, ., and /usr/local/etc/sane.d be-
ing searched (in this order).
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 exam-
ple, the slider that is used to select the picture from the camera may
not be updated immediately.
