Adding new product

Ganapati Hegde — 2012-05-16T12:03:35

Hi ,

 

I have a requirement to support new device , How can I integrate  new
product specific backend code with sane and to whom I need to send my
code.

My widgets are different from existing xsane frontend. Can I write my
own product specific frontend code and integrate with sane backend ?

 

Thanks

Ganapati Hegde

     Hello,

     this scanner (based on the USB ID) is supported by the genesys 
backend, including transparency adaptor since SANE 1.0.21. Maybe an 
access permission problem ? Checking the installed genesys.conf and 
dll.conf may also be worth.

     Another way to test is to do:
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL646=255
scanimage -L

Hi 

When I connect the scanner and turn it on, I get the following response:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

$ sane-find-scanner

Re: updating sane on Ubuntu 12.04 64 bit leavesxsaneusing old sane software

Richard Ryniker — 2012-05-13T12:50:06

When dynamic load libraries are changed (e.g. with the new files you
installed in /usr/lib/x86_64-linux-gnu/) it is necessary to execute

  /sbin/ldconfig

to update the cache used by the loader.  When libraries are updated by
package managers (aptget, dpkg, yum and others), this is done
automatically; when you build something yourself, it usually is not, in
order to allow a person to test the application before it is shared by
all users.

Of course, an application can be tested where it is built, before "make
install" is run, and that is clearly wise, but it also is useful to test
after "make install" and before general use, in case something in the
installation process is not right.

  /etc/ldconfig -p

displays the current cache contents, but does not change the cache.
Therefore, use of this command before and after /etc/ldconfig will
divulge what may have changed in the cache.

Hi

I have not developed Linux libraries, so there may be something obvious I
missed here ...

I want to use my Canon Pixma MP495 scanner from simple-scan. Sane on Ubuntu
12.04 seems old and doesn't include MP495 support.

After building and installing sane on my Ubuntu 12.04 64 bit system,
simple-scan and xsane were still using old drivers. I fixed this by
updating a link to point to the new sane. Is this correct behaviour?

I built and installed sane as follows

./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
make
sudo make install

After install I had (new drivers are dated 13 May)

Re: Epson Perfection V200 Photo - scans White as Blue

OK - the fragments were indeed automatic selections & I had not found 
the right-click to disable.
That works now, but needs doing every time in this version.
Good! - another reason to try it.
Thanks for the detailed instructions!
I normally steer clear of compiling & installing myself, but will give 
it a go.
Not for a couple of days though.

Thanks again for your interest!

Kåre Särs — 2012-05-12T14:08:57

The "Scanner Specific Options" are options that are just provided by the 
backend and are scanner/backend specific and not specially handled in any way 
in Skanlite (libksane). 

Gamma correction which is somehow handled could maybe update the preview, but 
there is a big risk that that correction would not be the same as what the 
backend provides.


That sounds like a bug somewhere... could the fragments be automatically 
selected selections? Automatic selections can be cleared through the right-
click menu of the preview. Automatic selections can be disabled in the 
settings in 0.8.

One possibility is to compile from sources (it is not difficult). 

# Install build dependencies 
sudo apt-get build-dep skanlite

# get the latest sources
git clone git://anongit.kde.org/skanlite

# build it
cd skanlite
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr ../
make

# Install
sudo make install

If you get problems with the above, mail me off-list.

Thanks for that suggestion, Kare.

I had not heard of Skanlite, but found it OK in Synapt & installed it - 
only version 0.7-2ubuntu3 in my Ubuntu 11.10 though.
I will try 0.8 when I upgrade Ubuntu to 12.04, but that will not be for 
several months yet (deliberate late adopter to avoid teething troubles).

Even this version successfully keeps general settings (format & quality, 
save-to-location etc) which is better than iscan at the moment in this 
respect.

Tone correction was not good though,  for several reasons, at least on 
first attempt (please correct if mistaken):
1. Corrections don't appear simultaneously in the preview display, so 
you have to stab in the dark then make another preview to see the result.
2. After correction (+10% brightness & +10% contrast could be about 
right) then impossible to select the scan area for a document, which 
then appears as numerous fragments...
3. Correction settings not retained (in this version).

Another problem is that the only dpi options are 300/2400/4800dp

I have noticed the lines:

checking for usb_interrupt_read in -lusb... yes
checking lusb0_usb.h usability... no
checking lusb0_usb.h presence... no
checking for lusb0_usb.h... no

in the output of ./configure. Maybe this is causing my problem? How do I
get the lusb0_usb.h?

With the latest release of Skanlite (0.8), all the settings are saved on exit

defaults). I think the relevant options with the epkowa backend is located in 
the "Scanner Specific Options" tab: Red, Shift green to red, ... 

Skanlite 0.8 is packaged with at least Ubuntu 12.04.

Thanks for the explanation, Olaf.

As you say, when using Image Scan! for Linux, then 'Document' setting 
does produce a slightly lighter 'white' than the 'Photo' setting, but 
not very significantly, and not enough.

What I do now with iscan, without bothering to check carefully, is to 
always make the same Tone correction, actually in the black rather than 
colour tabs & this gives a 'near enough' result for general use - see link:
http://s838.photobucket.com/albums/zz309/2CV67/?action=view&current=correction.png

If iscan would just remember my settings, that would be the end of the 
story, at least for iscan...

I assume from your explanation that nothing is going to make this white 
correction automatically for me, in any app, but is there nowhere in the 
whole chain of events I can make a once & for all manual adjustment?

Thanks for your patience ( as well as expertise, of course)!
