     Hello,

     we can do:

diff --git a/frontend/scanimage.c b/frontend/scanimage.c

           exit (1);
         }

-      if (!SANE_OPTION_IS_SETTABLE (opt->cap))
+      if (!SANE_OPTION_IS_SETTABLE (opt->cap) || opt->type == 
SANE_TYPE_GROUP)
         continue;

        option_number[option_count] = i;


  I can commit this if OK.

Sounds like we need to armor scanimage against this.

     Hello,

     I eventually found the root of the problem. Two option groups 
didn't have there .cap value defined explicitly. This was working until 
it broke recently, possibly related to the use of a newer compiler. 
However I pushed a fix in git, and now this issue is fixed.

Fwd: [Bug 1178405] Re: just scans 1 page

Stefano Prenna — 2013-06-17T19:26:04

Hello Team,

I'm not sure since when, but it seems that libsane is not working correctly
with my Canon LiDE 20. It only scans the first page and after that all the
scans end in a black page.

I've replicated this with simple-scan and xsane.

The output of xsane after export SANE_DEBUG_DLL=255 is attached.

IS this something related to libsane?

Thank you,
Stefano

  Incomplete

Bug description:
  I have a Canon CanoScan N67oU/LiDE20

  Since a few days (maybe after upgrade to 13.04.) the software just
  scans 1 page after starting the program.

  The other pages are scanned but either blank or black.

  More pages are only scanned after restart of the program.

pcap format.

Are there substantial differences (e.g., timing precision) between the
various formats (usbmon, pcap/ng, usbsnoop)?  Is there a preferred choice?

the closest support chip in genesys backend.

No problems keeping the livestream going for at least another month or so.
Also open to the idea of swapping out scanners if there are other
development targets.

     Hello,

     it took me some time to adapt my decoding scripts from usbsnoop to 
pcap format. I am now trying to find how much different it is from the 
GL124, which is the closest support chip in genesys backend.

     Hello,

     for me the scanimage code is perfectly correct. I don't think 
anything needs fixing in it. My "patch" is a workaround for a bug that 
comes from elsewhere.
So the ppa you built is working fine for you and failing for others ? 
Are glibc used different, or compiled with a different compiler ?

TPU negatives scan for Canon CS8800F and CS9000F

Rolf Bensch — 2013-06-14T16:01:25

Hi list,

I disabled TPU negatives scan for Canon for CS8800F and CS9000F with my
last commit.

I received some feedback, that negatives scan confuses the users.

The only difference between positives and negatives scan is one byte in
the protocol. I didn't found any visual difference between the scanned
images.

Anyway, converting negatives is part of the frontend (e.g. xsane) or
another external application.

Cheers,
Rolf

Somebody who is involved in coding scanimage should tell something about

If you use systemd, then systemd can be used to set the ACLs, but since 
I don't use systemd, I don't know much about it. Perhaps it's enough to 
just set the group ACLs and no user ACLs, so you could just delete the

Sane genesys Backend 1.0.24 CanoScan LiDE 210 and tiffscan format

Michael Watson — 2013-06-13T22:18:14

Greetings,

With archlinuxarm I've had no issues with the --format=tiff.  See below
example:

DPI=300
XFR=`gamma4scanimage 1.5 0 181 255 65535`
scanimage --device-name $SCANBD_DEVICE --resolution $DPI -l 0 -t 0 -x 215mm
-y 280mm \
     --custom-gamma=yes --gamma-table=$XFR \
     --format=tiff > ${TMPFILE}".tiff"


The only render issue I've had is related to ghostscript 9.07, so I've gone
back to 9.06.

Content-Type: text/plain; charset="us-ascii"

Hello,

I've got a problem with the 1.0.24 genesys backend. I need to use 1.0.24 
since the 5 front panel buttons of my CanScan LidE 210 are not fully 
supported in earlier versions.

When I try to scan in tiff format, this it what happens:

| tm< at >dungeonmaster:~ $ scanimage --format=tiff > /tmp/test.tiff
| scanimage: unrecognized option '--format=tiff'

It works with earlier versions of sane (tested with 1.0.22 and 1.0.23).

I use Kubuntu Linux 12.04 Precise Pangolin x86_64 and the 1.0.24git 
packages from this ppa: http://ppa.launchpad.net/rolfbensch/sane-git/ubuntu

scanimage --format=tiff works with the oroginal packages from the distro 
(Version 1.0.22-7ubuntu1) and from this ppa:
http://ppa.launchpad.net/nathan-renniewaldock/sane/ubuntu/ (Version 
1.0.23-0ubuntu1~ppa1~precise)

I tried building from the daily 1.0.24 snapshot sources myself, it gives 
the same results:

| tm< at >dungeonmaster:~ $ scanimage --format=tiff > /tmp/test.tiff
| scanimage: unrecognized option '--format=tiff'

Perhaps someone can shed some light on this. And BTW, there are some 
more long options that don't work any longer:
--icc-profile, --batch-* 

TIA for any help

Thorsten Müller — 2013-06-13T13:26:46

Hello,


I don't know if your problem still exists since it's about a month back 
you wrote about it, but I did not find any post regarding a solution.

Since the automagic setup by your distro's predefined udev rules seems 
to fail, we have to force udev doing our biding.

First, comment out the above line in 70-printers-rules.
Second, create a file /etc/udev/rules.d/99-samsung-scx4500w.rules

Third, add the follwing lines to the newly created file:

--- Start here ---
# ACL settings for Samsung SCX-4500W printer MFP
ATTR{idVendor}=="04e8", ATTR{idProduct}=="342b", GOTO="samsung"
GOTO="samsung_end"

LABEL="samsung"
RUN+="/bin/setfacl -m g:scanner:rw -m g:lp:rw $env{DEVNAME}"
TEST=="/var/run/ConsoleKit/database", \
RUN+="udev-acl --action=$env{ACTION} --device=$env{DEVNAME}"

LABEL="samsung_end"
--- Stop here ---

You can copy and paste the aboce lines. That should set the permissions 
for your multi function device so that sane, cups and your logged in 
users have complete access. Unplug and plug in again and see if that 
works.

Greetings
Thorsten

Hi all, I am new to this list and would like to know if my canoscan
N650U can be get working with Ubuntu, or if I have to lose my hope about
it. There is a bug filed here:

https://bugs.launchpad.net/ubuntu/+source/xsane/+bug/361278

where there are some informations, but they are quite old and at present
the behaviour is a little different (in Ubuntu 12.04).

So, if someone could guide me through any troubleshooting work, I would
very happy to make my own part of the job with testing, providing logs,
and so on.

Thank you very much,

Re: Fujitsu ScanSnap ix500 supported?

m. allan noah — 2013-06-12T01:55:15

I just committed backend version 117 to our development tree. This
includes a minor fix for a continuous feed problem with the iX500. All
other 'normal' scanning features are supported. WiFi however, is not.
Also, one user has reported some odd behavior related to higher
resolution color scans. I have not been able to reproduce, but wonder
if it might be related to USB 3 ports.

This should be available from our git snapshots tomorrow night. I
could walk you thru compiling it, or maybe someone builds a package
for Ubuntu. I don't use Ubuntu, so I don't know.
