[sane-devel] Hello, I am Fedora user using SANE for my DocketPort 685

[烏小龜]

Can I use SANE (scanimage) to get a duplex image from DocketPort 685

i have tried  "scanimage --help -d genesys:libusb:002:017"

it showed messags but i found that
"sensor:" was leaved blank , which meaned it didnt support "duplex" ?

the sane utility was complied by my own
I used sane-backends-1.0.22.tar.gz, libusb-0.1.12.tar.gz

Could you kindly  help me to get  a docketPort 685 duplex-supported sane
utility(scanimage) by modfication of source code or any other ways to
achieve it ?


Thanks a lot~

You need to add the -b argument to scanimage, if you want multiple
images. See man scanimage for details and other related options.

[sane-devel] Hello, I am Fedora user using SANE for my DocketPort 685

[烏小龜]

I am sorry, but -b seems not to solve my problems ><
I want to activate the duplex features of DocketPort 685
(DocketPort 685 is a duplex scanner with two sensors, up and down)
to scan a name card and *get its images of front and back at the same time.*

I've found an article teaching how to activate duplex feature through sane
but it is device-dependent. ( the artcicle is about Canon P-150 scanner)
The original link is here
http://ubuntuforums.org/showthread.php?t=1671216
According to the article , i've done the following steps
1. scanimage -L
output: device `genesys:libusb:002:003' is a Syscan/Ambir DocketPORT
685 flatbed
   scanner
2. scanimage --help --device-name canondr:libusb:002:002
output is in the tail of this mail
 (*the sensor field is blank, and i didnt found any useful option for
enabling duplex features , which means it doesn't support duplex feature?*)

Could anyone kindly tell me that Is there any modification of source code
(I've compiled sane on my own) or any other ways to use duplex feature of
DocketPort 685 through sane ?

Thank you for reading this ><

According to our support page:

http://www.sane-project.org/cgi-bin/driver.pl?manu=syscan&model=685&bus=any&v=&p=

the backend does not fully support duplex:

"front- and backside side-by-side, with backside mirrored horizontally."

Have you tried making your requested image wider?

Hello,

I confirm that the genesys backend doesn't handle duplex. The two 
sensors 
are used as a single wide sensor. When using full scan area width (which is 
about the double of the width of A4), you 'll get front picture on the left 
side, while the back's one will be on the right top down. So you'll have to 
cut the scanned picture in two and filp one of the parts.

Regards,
Stef

Hello, at first I have to thank you for reading my problem and give me
direction ^^

Double the width works, I can get both side in one image at  the same time.

But there is one another question . When I set the image to gray-scale
image (pgm)  by "scanimage -x 212 -y 120 --format=pnm > output.pgm"

Things goes very well. But if I set the image to color image(ppm) by
"scanimage --mode Color -x 212 -y 120 --format=pnm > output.ppm"

There seems to be some noises on the image. There are serveral yellow lines
on the front-side image of my name card, and the back-side is a good one.

I've also changed "-y 120" to "-y 90" range to "-y 140", and it didn't work.

Belows are my output image on dropbox .

Could you kindly tell me how to make the image good? Thank you ><

Hello,

you haven't calibrated yet your scanner with the calibration target 
(the 
with card with an horizontal black stripe). You can either use the 'calibrate' 
button in XSane or run 'scanimage -d genesys --calibrate >calib.pnm' .
SANE doesn't currently give a mean to signal users to do such calibration, you 
can't know what is going on unless you read the man page.

Regards,
Stef
