|
sane-artec_eplus48u - SANE backend for the scanner Artec E+ 48U and re-
|
|
badged models
|
|
|
|
|
|
</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-artec_eplus48u</B> library implements a SANE (Scanner Access Now
|
|
Easy) backend that provides access to several USB flatbed scanners
|
|
using the GT6816 chipset like the Artec E+ 48U. These scanners have a
|
|
contact image sensor (CIS).
|
|
|
|
A complete list of supported devices can be found on
|
|
<I>http://www.sane-project.org/sane-supported-devices.html</I>.
|
|
|
|
This is ALPHA software. Especially if you test new or untested scan-
|
|
ners, keep your hand at the scanner's plug and unplug it, if the head
|
|
bumps at the end of the scan area.
|
|
|
|
If you own a scanner other than the ones mentioned on the list that
|
|
works with this backend, please let us know this by sending the scan-
|
|
ner's exact model name and the USB vendor and product ids (e.g. from
|
|
<I>/proc/bus/usb/devices</I>, <B><A HREF="sane-find-scanner.1.html">sane-find-scanner(1)</A></B> or syslog) to me. Even if
|
|
the scanner's name is only slightly different from the models mentioned
|
|
above, please let me know.
|
|
|
|
|
|
</PRE>
|
|
<H2>KERNEL ISSUES</H2><PRE>
|
|
If libusb-0.1.6 or later is installed, this section can be skipped. The
|
|
scanner should be found by <B><A HREF="sane-find-scanner.1.html">sane-find-scanner(1)</A></B> without further
|
|
actions. For setting permissions and general USB information look at
|
|
<B><A HREF="sane-usb.5.html">sane-usb(5)</A></B>.
|
|
|
|
When you are using the scanner module, a Linux kernel 2.4.12 or newer
|
|
is required.
|
|
|
|
|
|
</PRE>
|
|
<H2>FIRMWARE FILE</H2><PRE>
|
|
You need a firmware file for your scanner. That's a small file contain-
|
|
ing software that will be uploaded to the scanner's memory. For the
|
|
scanners mentioned above, it's usually named <I>Artec48.usb</I> or <I>1200.usb</I>.
|
|
You can find it on the installation CD that was provided by the manu-
|
|
facturer, normally in the directory Win98, WinMe or similar. If the
|
|
Windows-driver is installed on your computer, then you can also find
|
|
the firmware file under <I>c:264vers</I>.
|
|
|
|
|
|
</PRE>
|
|
<H2>CONFIGURATION</H2><PRE>
|
|
The contents of the <I>artec</I><B>_</B><I>eplus48u.conf</I> file is a list of usb lines
|
|
containing vendor and product ids that correspond to USB scanners. The
|
|
file can also contain option lines. Empty lines and lines starting
|
|
with a hash mark (#) are ignored. The scanners are autodetected by <I>usb</I>
|
|
<I>vendor</I><B>_</B><I>id</I> <I>product</I><B>_</B><I>id</I> statements which are already included into
|
|
<I>artec</I><B>_</B><I>eplus48u.conf</I> <I>.</I> "vendor_id" and "product_id" are hexadecimal
|
|
numbers that identify the scanner.
|
|
|
|
Every usb section can have additional options.
|
|
|
|
<B>artecFirmwareFile</B> <B>/usr/local/share/sane/artec_eplus48u/Artec48.usb</B>
|
|
The path to the firmware file. This option is required.
|
|
|
|
<B>redGamma</B> <B>1.0</B>
|
|
|
|
<B>greenGamma</B> <B>1.0</B>
|
|
|
|
<B>blueGamma</B> <B>1.0</B>
|
|
|
|
<B>masterGamma</B> <B>1.9</B>
|
|
These are the default gamma values. If you set the "Defaults"
|
|
option with a frontend, then the gamma options are reset to the
|
|
values specified here.
|
|
|
|
<B>redOffset</B> <B>0x28</B>
|
|
|
|
<B>greenOffset</B> <B>0x2f</B>
|
|
|
|
<B>blueOffset</B> <B>0x2f</B>
|
|
|
|
<B>redExposure</B> <B>0xa7</B>
|
|
|
|
<B>greenExposure</B> <B>0x116</B>
|
|
|
|
<B>blueExposure</B> <B>0xdc</B>
|
|
These are the default values for offset and exposure time. You
|
|
can change them (e.g. to speed up calibration) if you don't want
|
|
to save the calibration data permanently.
|
|
|
|
<B>vendorString</B> <B>Artec</B>
|
|
|
|
<B>modelString</B> <B>E+</B> <B>48U</B>
|
|
By default, the scanner is reported as "Artec E+ 48U". If you
|
|
don't like this, e.g. because you have an Tevion MD 9693, then
|
|
change the options accordingly.

<H2>FILES</H2><PRE>
|
|
<I>/usr/local/etc/sane.d/artec</I><B>_</B><I>eplus48u.conf</I>
|
|
The backend configuration file (see also description of
|
|
<B>SANE_CONFIG_DIR</B> below).
|
|
|
|
<I>/usr/local/lib/sane/libsane-artec</I><B>_</B><I>eplus48u.a</I>
|
|
The static library implementing this backend.
|
|
|
|
<I>/usr/local/lib/sane/libsane-artec</I><B>_</B><I>eplus48u.so</I>
|
|
The shared library implementing this backend (present on systems
|
|
that support dynamic loading).
|
|
|
|
|
|
</PRE>
|
|
<H2>ENVIRONMENT</H2><PRE>
|
|
<B>SANE_CONFIG_DIR</B>
|
|
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
|
|
<I>/usr/local/etc/sane.d</I>. If the value of the environment variable
|
|
ends with the directory separator character, then the default
|
|
directories are searched after the explicitly specified directo-
|
|
ries. For example, setting <B>SANE_CONFIG_DIR</B> to "/tmp/config:"
|
|
would result in directories <I>tmp/config</I>, <I>.</I>, and
|
|
<I>/usr/local/etc/sane.d</I> being searched (in this order).
|
|
|
|
<B>SANE_DEBUG_ARTEC_EPLUS48U</B>
|
|
If the library was compiled with debug support enabled, this
|
|
environment variable controls the debug level for this backend.
|
|
Higher debug levels increase the verbosity of the output.
|
|
|
|
Example: export SANE_DEBUG_ARTEC_EPLUS48U=3

|
|
Vlasov, Andreas Nowack, and David Stevenson. Thanks to everyone who
|
|

<H2>BUGS</H2><PRE>
|
|
This backend has been tested on Linux only. If you are using it on a
|
|
different platform, please contact us.
|
|
|
|
Interpolation with 1200 dpi is weak.
|
|
|
|
Support for buttons is missing due to missing support in SANE.
|
|
|
