Are you a manufacturer or vendor of scanners and one of your scanners is not supported by <a
|
2018-02-28 13:33:00 +00:00
|
|
|
href="./">SANE</a> yet? As Linux and other Unix systems become more and more popular, many
|
2003-09-23 19:44:12 +00:00
|
|
|
people check for SANE support when buying scanners. A logo "Supported by SANE" or "Runs on
|
|
|
|
|
Linux" or similar would be nice, wouldn't it? Also an existing SANE backend would mean that
|
|
|
|
|
your scanner is no longer listed as <a
|
2005-10-03 15:35:30 +00:00
|
|
|
href="lists/sane-backends-cvs.html#S-UNSUPPORTED">unsupported</a> in our lists and you could add
|
2003-09-23 19:44:12 +00:00
|
|
|
"Linux support" to the list of features on your website.
|
|
|
|
|
</p>
|
|
|
|
|
<p>
|
|
|
|
|
As you are the manufacturer of the device, you have all the information necessary to write a
|
|
|
|
|
SANE backend (driver). That makes it much easier for you to do it than for any other
|
|
|
|
|
person. Most probably you only need to port your MS Windows code to SANE. You can ignore all
|
|
|
|
|
the graphical interface code as SANE already provides a variety of <a
|
|
|
|
|
href="sane-frontends.html">frontends</a> (scanning applications). You only need the code for
|
|
|
|
|
accessing the scanner. For details on how to write a driver see our <a
|
|
|
|
|
href="contrib.html">contributing page</a>.
|
|
|
|
|
</p>
|
|
|
|
|
<p>
|
|
|
|
|
I recommend to use the <a href="license.html">GPL + SANE exception</a> license for your
|
|
|
|
|
code. So it can be included in the SANE distribution and your driver will come with most Linux
|
|
|
|
|
distributions. Furthermore you can use the existing code for USB and SCSI access and many
|
|
|
|
|
helper functions so you don't need to think about the low level details. And your scanner will
|
|
|
|
|
be supported not just on one operating system and platform but on everything SANE runs on (see
|
|
|
|
|
our <a href="sane-support.html">platforms page</a>). Providing source code makes it easier for
|
|
|
|
|
other developers to give feedback and send patches for bugs.
|
|
|
|
|
</p>
|
|
|
|
|
<p>
|
|
|
|
|
If you can only release binary SANE backends that's better than nothing but still not
|
|
|
|
|
recommended. The SANE standard itself is public domain, so you are free to use it. But keep
|
|
|
|
|
in mind that you must adhere to our <a href="license.html">license</a> if you use parts of the
|
|
|
|
|
SANE code. Binary-only drivers mean you can't get help from us or any SANE users because
|
|
|
|
|
nobody can debug your code. Binary-only drivers can not be included in the official SANE
|
|
|
|
|
releases.
|
|
|
|
|
</p>
|
|
|
|
|
<p>
|
|
|
|
|
Yet another option is to publish complete programming information or the source code of the
|
|
|
|
|
scanner drivers for MS Windows. With this information it's much easier for a free software
|
|
|
|
|
developer to create a backend. Some manufacturers don't like to publish this information but
|
|
|
|
|
give it to selected developers only. That's possible, but the backend code will be GPL most
|
|
|
|
|
likely so at least part of the information will be public anyway. If you intend to publish
|
|
|
|
|
programming information, you may want to ask on the <a
|
|
|
|
|
href="mailing-lists.html">sane-devel mailing list</a> if anyone is
|
|
|
|
|
interested in programming a driver. But keep in mind that providing programming information is
|
|
|
|
|
not a guarantee that a driver will ever be written.
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
The most important part is communication: Please tell us what you intend to do. We are also
|
|
|
|
|
interested in partial information, e.g. if some scanners use the same chipset as others. That
|
|
|
|
|
may help to write backends for a variety of devices. Also tell us if any of the information in
|
|
|
|
|
our lists is missing or wrong. So please contact the <a href="mailing-lists.html">sane-devel
|
|
|
|
|
mailing list</a> with your information and ideas. If you don't want to subscribe to this list,
|
|
|
|
|
please write to Henning Meier-Geinitz (<a
|

|
