I've been writing up a proposed SANE 1.2 draft document, based on sane.tex<br>
|
||
from the SANE 1.0.1 distribution.<br>
|
||
<p>
|
||
However, when it came to adding JBIG (which someone mentioned wanting) I<br>
|
||
noticed that JBIG uses the exact same arithmetic coding stuff which was<br>
|
||
patented by IBM and thus lies unused in the JPEG standards.<br>
|
||
<p>
|
||
At the moment I have explicitly mentioned the patented process as a no-no<br>
|
||
in the JPEG frame type, which makes sense because hardly anything can<br>
|
||
read JPEG streams with arithmetic encoding anyway. For JBIG we don't have<br>
|
||
that option because the patented Q-coder is in the baseline standard.<br>
|
||
<p>
|
||
So: A question for those writing drivers for high-speed document scanning<br>
|
||
<p>
|
||
Should we include a JBIG frame type anyway? If we do it will be the first<br>
|
||
format for which SANE cannot include a reference implementation. The<br>
|
||
advantage in supporting it anyway would be that you could potentially<br>
|
||
save the JBIG image (if an interchange format exists) and import it into<br>
|
||
your proprietary document management system. The disadvantage is that<br>
|
||
this sets an unpleasant precedent.<br>
