Re: [sane-devel] Please: CanoScan Lide 220
If you could provide the exact versions of sane-backends and sane-frontends you are using, that would be more useful. I have a Canon CanoScan LiDE 220 sitting right next to me and it is functioning quite well (I'm using scanimage to drive it). Try running $ scanimage -d genesys --format=tiff --resolution 75 > test.tiff and see if that works as expected. I often find that the thing that's making the scanner not work is the application, not the SANE driver.

[sane-devel] Please: CanoScan Lide 220
Please help to breathe a life of my scanners Lide 220... Please... Thx. csola48 ps.: Happy Easter for everybody! :) -- sane-devel mailing list: sane-devel@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject "unsubscribe your_password" to sane-devel-requ...@lists.alioth.debian.org
[sane-devel] [PATCH 1/2] Separate ICC profile loading into a separate file.
This cuts out some duplicate code, and enables us to reuse this
logic for PNG, JPEG, and any other future output format.
sanei_load_icc_profile also allows us to know that an ICC profile
file is not long enough before we start to write it to the output;
this should prevent poorly-written software from overflowing into
image data when they read the bad profile based on its length.

Re: [sane-devel] scanbd and Canon LiDE 60: buttons not recognized ?
Hi Wilhelm,
thanks for your patch, works like a charm - I just had to made a small
modification since
the backend name inside the wrapper actually is "Genesys USB" (see below).
A minor hint for those who tinker around like me: Do no forget to turn
debugging off in
scanbd.conf when finished, otherwise syslog will overflow :-)
Regards,
Florian

Hi Wilhelm,
thanks, your modification made all four buttons work !
Great!
This seems somewhat surprising to me at first glance, should the
backend not be strcmp'ed using "==0", providing
an own section for each backend :-) ? Anyway, it works, even if the
buttons are somewhat scrambled:
Please backout the last patch I sent and now apply the attached one.
This should mark your buttons with the right labels.
If thats ok for you, I'll check this into trunk.

I also used string-triggers only. The buttons may have to be pressed for
a short period exceeding the polling interval.
Some minor possible pitfalls using the installations defaults of
scanbd-1.5.0 under Ubuntu 16.04:
- I removed the default package and configured the newer scanbd 1.5.0 as
described in the previous mail. I also used xinetd instead of the ubuntu
default
bsd-inetd for network scanner access although this should be of no
relevance.
- Wilhelms patch has to be applied to scanbuttond_wrapper.c (removed
assertion, return strings on any value of "button").
- In scanbd.conf: Group should be "saned". Make sure all paths refer to
/usr/local/etc/scanbd, scriptdir = /usr/local/etc/scanbd/scripts, ...
- The new path also enters into /lib/systemd/system/scanbd.service,
after changing that do "systemctl daemon-reload" and restart scanbd.
Now I am happy because of the four programmable buttons for my Odroid-U2
SoC which has no monitor attached to it :-)
Thanks again Wilhelm and Happy Easter !

Looking into the list of supported devices of libsane, you'll find that the HP 6300C has complete support. Looking into the sources of scanbuttond I don't see any support. So, scanbd with libsane will do the trick if querying the button-options is implemented in the backend for the HP6300C ...

Re: [sane-devel] [sane-genesys] Support for Plustek Smartscan PL1500 - chip GL843
Hi, This scanner didn't appeared on http://www.sane-project.org/sane-mfgs.html since my last mail, do I have something else to do ? I have seen that in genesys_devices.c, there is some model specific properties, so I think that I had no chance to get it work with the ubuntu tutorial (edition of /etc/sane.d/dll.conf and /etc/sane.d/genesys.conf). I have seen in mailing list archive that Plustek offered some helps to develop sane backends, but no news since then. [1] http://lists.alioth.debian.org/pipermail/sane-devel/2016-November/034854.html [2] http://lists.alioth.debian.org/pipermail/sane-devel/2016-November/034872.html Does the genesys sane back-end development is stopped until some news from Plustek ?In the thread, Gerhard Jäger said that in the good old days I did a similar thing for the Plustek backend. In fact I had an NDA and the allowance to use their code - in fact Windoze driver code. http://lists.alioth.debian.org/pipermail/sane-devel/2016-November/034865.html Do I have any chance to achieve to find the good values for genesys_devices.c ? Is it sufficient for enabling support for this scanner ? I have some programming skills, but mainly in java, however, C doesn't afraid me too much. Linux shell is ok. Where do I have to start ? - Decompilation ? I have done some decompilation in java, but never in C, what (affordable) software can I use ? (IDA is a bit expensive). - USB sniffing ? Same question, what software do you advise ? - Other ? Thank'sQuentin B.
