I wrote a custom driver which does IR (well, kind of; that is my problem) and at the same time talking with Gernot about the SANE 8800F driver. As often suggested a custom driver is easier when exploring a unknown scanner but the solution may later be transportable into SANE. Need that solution first. Regards, Enno
[sane-devel] Canon 8800F infrared scan
I am scanning negatives on a Canon scanner, both normal RGB and then infrared. The alignment of visible dark (light after inversion) patches in rgb and the IR patches is poor and varies in a for me unpredictable way from patch to patch. Would like to get in touch with anyone having similar results or suggestions or even solutions. Regards, Enno

well, then I would start with windows snoops of the IR in action, and make sure you are sending the same commands. allan On Sat, Mar 27, 2010 at 1:18 PM, Enno Fennema wrote: > m. allan noah wrote: >> Uhm- how are you scanning IR in sane with an unsupported scanner? > > You are right.

Uhm- how are you scanning IR in sane with an unsupported scanner? allan On Sat, Mar 27, 2010 at 10:50 AM, Enno Fennema wrote: > I am scanning negatives on a Canon scanner, both normal RGB and then > infrared.

Can you write the letters 'RGB', each in the correct color, in the upper left corner of a paper, and get a log of a low resolution color scan of that area? allan -- "The truth is an offense, but not a sin" -- next part -- A non-text attachment was scrubbed...
