− SANE backend for Kodak DC20/DC25 Digital Cameras
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.
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.
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 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
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.
