Hey stef,
I see things seem to be progressing well with the lide 110, good times!
I have recently had a problem with the account I set up the mailing list
with so I have added this account instead. I doubt there will have been
any progress on the plustek drivers, but as I've missed some of the
Chris, please go ahead. I think you could remove some of my Chris
why comments where you know. Should the scanner be added also to the
genesys.conf
Definitely here
and libsane.rules files?
I have never entered in this file, what was the reason behind adding to
it? Or at least what does it
Thanks Stef, a week is no problem for me, i'm pretty busy at work at the
minute so a weeks time might work out best for all of us.

Cheers Allan, Stef said hes gonna give the code a thorough look through
in a week or so, should be plenty of time for the next release if it is
around your proposed time.

Hi Stef, I take it that you have now received my preliminary copy of my
report. I will send you a completed copy when I am done.
I have a question about the image scans at 1200+ dpi. When attempting
scans at these resolutions I only get half an image. A little
investigation has led me to find
I know this was discussed about 6 weeks ago but is there any update on
when the next SANE release will be? Would be nice to know a rough date
or at least if progress is being made
Thanks

Hello,
for the image quality, I think you could concentrate on on full sensor
resolution and 'half ccd' resolution.
I'm not sure what you mean but I guess full resolution is the maximum
hardware resolution of the scanner? If so then what is 'half ccd'
resolution?

Hello,
regarding the gamma values you can extract the gamma tables sent to your

you can insert the formula used by the genesys backend and compare the
