</EM><BR>
|

<EM>> Thanks to Tom for his pointing out that his sane-bh backend DOES support

|
|
<EM>> compression.
|

</EM><BR>
|
|
<EM>> Why isn't it directly integrated with SANE 1.04 and part of the standard
|
|
</EM><BR>
|
|
<EM>> distribution ? The latest sane-bh patches are against 1.03, so I guess
|
|
</EM><BR>
|
|
<EM>> there'll be some extra work required to make it go together with 1.04 ?
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> The obvious question arises : When is "the next major version of SANE" due
|
|
</EM><BR>
|
|
<EM>> to be released ? It would seem to me (maybe naively) that scanner-based
|
|
</EM><BR>
|
|
<EM>> compression is something that has been overlooked in SANE up until now.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Is there any reason that a "reference model" scanner from the SCSI II spec
|
|
</EM><BR>
|
|
<EM>> wasn't developed as part of SANE, as a basis for all others to be modelled
|
|
</EM><BR>
|
|
<EM>> on ? Obviously every manufacturer likes to "roll their own" feature set,
|
|
</EM><BR>
|
|
<EM>> but we seem to be treading on each other's toes by re-inventing at least
|
|
</EM><BR>
|
|
<EM>> some portion of the wheel for each new scanner. e.g. with sense code /
|
|
</EM><BR>
|
|
<EM>> qualifier decoding for the various error messages such as ADF jamming.
|
|
</EM><BR>
|
|
<EM>> Perhaps it's time to look at redesigning the backends to deal with these
|
|
</EM><BR>
|
|
<EM>> e.g. a function called sane_scsi2_asc60_asq00 might actually handle the SCSI
|
|
</EM><BR>
|
|
<EM>> 2 ASC60, ASQ00 response code "Lamp failure" for all scanners. Perhaps this
|
|
</EM><BR>
|
|
<EM>> also lends itself to other (multi language support ?) also if the SANE API
|
|
</EM><BR>
|
|
<EM>> could be extended to cover some sort of SANE_Status to text translation
|
|
</EM><BR>
|
|
<EM>> scheme.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Or am I just barking up the wrong tree ???
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> There also seems to be a large discrepancy in the level of diagnostic given
|
|
</EM><BR>
|
|
<EM>> in each driver e.g. the Microtek driver seems to be absolutely LOADED with
|
|
</EM><BR>
|
|
<EM>> debugging information (over 119 printfs, plus stacks of DBG callouts), but
|
|
</EM><BR>
|
|
<EM>> others have very few at all.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Then again, maybe I'm just used to being pampered by pay-ware rather than
|
|
</EM><BR>
|
|
<EM>> GPL-ware ;-)
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Is there a list of proposed features (or just a wish list by SANE users) for
|
|
</EM><BR>
|
|
<EM>> the next version ?
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Just curious
|
|
</EM><BR>
|
|
<EM>>
|

</EM><BR>
|
|
<P>Jason,
|
|
<BR>
|
|
<P>in July or August 1999 was a larger discussion on the Sane mailing list
|
|
<BR>
|
|
about a new version of the Sane standard, including the question about
|
|
<BR>
|
|
more data formats. Technically quite interesting, I think. Unfortunately
|
|
<BR>
|
|
the debate ended up in some not very polite arguments. Since this time,
|
|
<BR>
|
|
nobody dared to pick up the topic again.
|
|
<BR>
|
|
<P>But I don't think that this outcome is a required feature of GPL
|
|
<BR>
|
|
developement, only an optional one ;-)
|
|
<BR>
|
|
<P>Abel
