well, it is not absurd for an user to install
a recent -dev package if he wants to compile a recent
frontend.
if a frontend author wants ease the burden of its users, we
can just provide a s

why an 1.1 capable frontend should compile against sane 1.0?

Best regards,
Alessandro Z
An 1.1 compliant frontend should:
1) check for sane version >= 1.1 (a macro will be provided)
2) call sane_control_option
int supported_version = SOMEMACRO(1,1);
sane_control_option(handle, 0, SANE_ACTION_, &supported_version,
NULL);
3) the backend can then expose sa

Hello,
I made two tests today :
test 1 : too bright/too dard = 10/65525 WITH flag :
SCAN_FLAG_DISABLE_LAMP. Result can bee found on :
http://ggastebois.free.fr/lide90_snoop/18_test1.tar
test 2 : too bright/too dard = 10/65525 WITHOUT flag :
SCAN_FLAG_DISABLE_LAMP. Result can bee found on :

the new hp3900 backend supports this scanner. please see:
http://www.sane-project.org/sane-backends.html#S-HP3900
and

you will have to build sane 1.0.19 or the current cvs version from
source to get this code, and you might want to contact the au

Updated the pixma external desc file, and renamed MultiPass MP710/MP740 to
Pixma MP710/MP740 as suggested in desc and man files.

feel free to update the comment in canon_mfp.desc. you can even put in

Hi, i have a problem running as normal user. When i call sane_open it
return a null SANE_Handler. this doesn't happen as root (it work fine)
Also i can detect the scanner as normal user and scan with scanimage.
So i thing it not problem with permissions
Any help will be apreciated.

Ok, sounds good to have also an up to date repository of Canon?s proprietary
scanner backends
However, one point about those Canon backends:
- Only executable code available,
- Work only with Canon?s scangearmp software
- Seem to be designed for Sane, but AFAIK (self experience on Pixma MP610

I am looking for a documentscanner. I saw the HP scanjet 7800. Some
internetsites gives the information LINUX driver on request. HP does not
have a driver. Is there a 7800 driver in SANE?
SANE_Handle is opaque, you should not try to interpret its value as a
pointer. what status code do you get?

it is not in our supported devices page, so there is no known SANE
support. it is possible that the machine may use a supported chip, we
just dont know about it.
however, the similar looking N4010 (iirc) used an arm-based cpu, and a
very different looking protocol, for which HP would not provide

yes- we should make a little effort to keep the external backends files updated.
