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
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:

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
SANE_DEBUG_DC25 [Toc] [Back]
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.
