.SH NAME
|
||
|
|
sane-cardscan \- SANE backend for Corex CardScan 800c usb scanner
|
||
|
|
|
||
|
|
.SH DESCRIPTION
|
||
|
|
The
|
||
|
|
.B sane-cardscan
|
||
|
|
library implements a SANE (Scanner Access Now Easy) backend which
|
||
|
|
provides access to the Corex CardScan 800c small-format scanner.
|
||
|
|
|
||
|
|
The backend supports only grayscale and color modes and media of
|
||
|
|
(theoretically) infinite length.
|
||
|
|
|
||
|
|
This backend may support other scanners. The best
|
||
|
|
way to determine level of support is to get a trace of the windows
|
||
|
|
driver in action, and send it to the author.
|
||
|
|
|
||
|
|
.SH OPTIONS
|
||
|
|
The cardscan backend supports the following options:
|
||
|
|
.PP
|
||
|
|
mode m
|
||
|
|
.RS
|
||
|
|
Selects the mode for the scan. Options are "Gray" and "Color".

||

||
|
|
.SH CONFIGURATION FILE
|
||
|
|
The configuration file "cardscan.conf" is used to tell the backend how to look
|
||
|
|
for scanners, and provide options controlling the operation of the backend.
|
||
|
|
This file is read each time the frontend asks the backend for a list
|
||
|
|
of scanners, generally only when the frontend starts. If the configuration
|
||
|
|
file is missing, the backend will use a set of compiled defaults, which
|
||
|
|
are identical to the default configuration file shipped with SANE.
|
||
|
|
.PP
|
||
|
|
Scanners can be specified in the configuration file in 2 ways:
|
||
|
|
.PP
|
||
|
|
"usb 0x04c5 0x1042" (or other vendor/product ids)
|
||
|
|
.RS
|
||
|
|
Requests backend to search all usb busses in the system for a device
|
||
|
|
which uses that vendor and product id. The device will then be queried
|
||
|
|
to determine if it is a cardscan scanner.
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
"usb /dev/usb/scanner0" (or other device file)
|
||
|
|
.RS
|
||
|
|
Some systems use a kernel driver to access usb scanners. This method is untested.
|
||
|
|
.RE
|
||
|
|
|
||
|
|
.SH ENVIRONMENT
|
||
|
|
The backend uses a single environment variable, SANE_DEBUG_CARDSCAN, which
|
||
|
|
enables debugging output to stderr. Valid values are:

||
|
|

|
.PP
|
||
|
|
.RS
|
||
|
|
The scanner does not seem to have much control possible, so the backend
|
||
|
|
cannot set x/y coordinate values, resolutions, etc. These things could
|
||
|
|
be simulated in the backend, but there are plenty of command line tools.
|
||
|
|
.br
|
||
|
|
.br
|
||
|
|
The backend also does not send all the commands that the windows driver
|
||
|
|
does, so it may not function the same.
|
||
|
|
.br
|
||
|
|
.br
|
||
|
|
The backend does not have the calibration or ejection options of the
|
||
|
|
windows driver.
