Re: [sane-devel] Fujitsu Backend

[m. allan noah]

Yes, I mistyped- the backend should auto detect the need for LUT on the
ix1500 too. I'll note that your example command lines have weird emdashes
before the contrast and brightness, not a proper double dash. Any chance
that is related?

If not, can you get a debug log like so:

SANE_DEBUG_FUJITSU=35 scanimage --mode=gray --contrast=20 --brightness=20
--format=tiff --ald=yes  --device-name=fujitsu:ScanSnap\
iX1500:94839  --resolution=200  --batch=Scan-Designer-TAWS27-144246-%d.tif
2>ix1500.log

then compress ix1500.log and send it to me directly?

Re: [sane-devel] Fujitsu Backend

[Tom Buckler]

It's with the ix1500's not 500. I also have an ix100 that works fine.

So for example 
/usr/local/bin/scanimage --mode=gray —contrast=20 —brightness=20 --format=tiff 
--ald=yes  --device-name=fujitsu:ScanSnap\ iX1500:94839  --resolution=200  
--batch=Scan-Designer-TAWS27-144246-%d.tif 
Looks exactly the same as 
/usr/local/bin/scanimage --mode=gray —contrast=-40 —brightness=0 --format=tiff 
--ald=yes  --device-name=fujitsu:ScanSnap\ iX1500:94839  --resolution=200  
--batch=Scan-Designer-TAWS27-144246-%d.tif 

Note this is with 1.0.28, where I've added this model to fujitsu.conf.

Re: [sane-devel] Fujitsu Backend

[m. allan noah]

Some fujitsu machines have native brightness/contrast support, others
require that a LUT be calculated by the backend and uploaded. I don't think
there is a way to detect which is needed. I will investigate further.

[sane-devel] Fujitsu Backend

[Tom Buckler]

Hi Allan,

Do you know if the iX1500 should respond to —contrast and —brightness ? I'm not 
getting any change with those parameters, and no details in the manpage. 
—resolution —mode —ald work just fine…

Thx,
Tom
