sane-dc25(5) SANE Scanner Access Now Easy sane-dc25(5) NAME sane-dc25 - SANE backend for Kodak DC20/DC25 Digital Cameras DESCRIPTION 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. DEVICE NAMES The current version of the backend only allows one camera to be con- nected. 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 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 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 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: port=/dev/ttyS0 # this is a comment baud=115200 dumpinquiry FILES /usr/local/etc/sane.d/dc25.conf The backend configuration file (see also description of SANE_CONFIG_DIR below). /usr/local/lib/sane/libsane-dc25.a The static library implementing this backend. /usr/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 direc- tories are separated by a colon (`:'), under OS/2, they are sep- arated 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 /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). 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. SEE ALSO sane(7) AUTHOR Peter Fales, dc25-devel@fales-lorenz.net. 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 exam- ple, 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. 11 Jul 2008 sane-dc25(5)
