Re: [sane-devel] Experience with the v4l backend?
Did you check if device is working with for example the program "cheese" works with UVC devices For this program maybe you have to disable the v4l backend in /etc/sane.d/dll.conf Regards, Gerard Klaver On Thu, 2017-01-05 at 22:28 +0100, Torfinn Ingolfsen wrote: > Hello, > Does anyone here have experience with the v4l backend? > I recently got myself a CZUR ET16 scanner[1,2] and it shows up as a > video device, that is why I have to use the v4l backend.

Re: [sane-devel] SANE; scanning with LIDE series works under Win, NOT under Lx
Hello Cedric,
Also check in your home directory .sane/xsane files, maybe removing .xsane
and start again xsane could help.
Also if installed sane frontend, xscanimage could be helpfull to scan.

Hi Cedric,
For someone who claimed not to be a techie 2 days ago, you're doing
remarkably well.
- ICM Profile: http://linuxforums.org.uk/index.php?topic=10200.0
On linux, debug and log files are usually sent to /var/log. There's no
fixed sane debug or log file as far as I know.
Try this from a terminal:
$ SANE_DEBUG_SANEI_USB=80 xsane

Thanks a lot Stijn and Allan ! I made some progress.
Here goes:
_Background_:
sane and libsane version 1.0.23 on Ubuntu 14.04.2
scanner Canon LIDE25 works under Windows but not Linux
scanimage functions perfectly with scanner in identical conditions
under Lx.
It turns out that just like for this post
http://askubuntu.com/questions/599694/scanimage-works-but-xsane-or-any-other-ui-does-not
on askubuntu.com, I am running 'tlp' for power saving optimization. I
applied the post's author's solution by tweaking the 'tlp' config
file, so that USB autodisable would not affect my LIDE25
(0x04a9:0x2220).
After applying the change to the tlp config file, I checked it from
terminal:
$ cat -n /etc/default/tlp | egrep USB_BLACKLIST
173#USB_BLACKLIST=: :
178USB_BLACKLIST=04a9:2220
187USB_BLACKLIST_WWAN=1
Result:
'simplescan' now works for the first time in 2 months or so (though it
seems awfully slow to me).
'xsane' (the frontend I favor) gives me:
Error during CMS conversion: could not open scanner ICM profile.
The above error message appears when I launch 'xscan', when I try to
change any setting and when the scan is over.
Trying to scan, the scanner goes through all the moves at a normal
speed) but scan everything blank.
So I tried four things:
*1)* Following another post cid:part2.06040302.04030204@gmail.com, I
created the new rule:
$ sudo vi /etc/udev/rules.d/40-libsane.rules |
ATTRS{idVendor}== 04a9, ATTRS{idProduct}==2220,
ENV(libsane_matched)=yes|||
$ sudo chmod 644 /etc/udev/rules.d/40-libsane.rules
'simplescan' 's behavior is unchanged. It scans in mode gray, color.
All good.
Relaunching 'xsane' I did NOT get any more error messages. However,
although 'xsane' launched and allows the scanner to do previews and
scans without complaining, EVERY preview or scan comes out blank, even
after reboot.
*2)* I set my debug log level to 80 (don't really know what level
between 1 and 128 I should use here)
$ SANE_DEBUG_SANEI_USB=80
$ export SANE_DEBUG_SANEI_USB
However I know neither where log files are located, nor how I should
post them for review.
Perhaps s.o. can help me with hints on that.
*3)* I edited the sane.d genesys.conf file to include a reference to
Canon LiDE 25
sudo vi /etc/sane.d/genesys.conf
# Canon LiDE 25
usb 0x04a9 0x2220*
4)* Following Allan's suggestion I checked whether my bios/kernel
relies on
xhci_hcd
It does not, apparently. It seems to rely on 'ehci-pci' as seen from
the command
$ dmsg | tail
ran upon plugging my LiDE 25 scanner onto the 7-1 usb port.

I believe I do not have any USB3 issue. I simply do not have USB3

Nevertheless knowing that power management is also effected at kernel
level, via the usbcore.autosupend parameter and I did:|
$ modprobe usbcore autosuspend=-1
|That did not have any benefical effect and I reversed the action:
|
$ modprobe usbcore autosuspend=2|
Can somebody further suggest something ?
Also I need help with the debug log files. Where are they located and
how do I post them ?
Thanks.

I would definitely concur with Wouter's fecal characterization of the
available Windows scanner software. Even XP's own scanner program beats
the HP one, which I assure you is faint praise indeed.
I took mine apart and found an Avision C7C chip (it's in the bug report,
with links to pics of the board).
There were no results for either 'N6350' or 'N8460' on the
hplipopensource.com site search function.
I tried running 'hp-check' per m. allan, and the program reports that
everything seems to be set up properly (on my Ubuntu 12.04.2 64 bit), but:
* 'No scanners were identified', and
* Under 'USB I/O SETUP' it does find the device, but reports 'error:
Unsupported model: HP_Scanjet_N8400'
I suspect that hplip will not work with Wouter's device either, but I'll
look forward to seeing what he finds.

Hi folks,
As I blogged recently[1], I own an HP ScanJet N6350 that TTBOMK does not
work with SANE, and of which the Windows software is just crap.
I'd like to see if I can reverse engineer the protocol (USB and/or
network). This should at the very least be possible, as I'm already
running Windows inside a VM; so it should just be a matter of using
wireshark on the USB and/or network interface.
Now I do think I have a general idea of how to reverse engineer a
protocol, but I've never actually done anything of the sort before. Is
there something I should pay specific attention to when doing this sort
of thing?
Additionally, once I've figured out the protocol (or have gathered
enough data), is there somewhere I could send it? I don't think I have
the understanding of the SANE internals to do write the driver myself...

For the HP N8460,
Did you check for the sane-avision backend, IIRC some scanners with an

[sane-devel] maximum image size for a scan for Canon pixma backend

So the scanner is now supported for all modes. However, for large images at both 4800dpi and 9600dpi modes, it seems the max size of the image is limited in some way, so that only a section of the desired image is delivered.

An A1 or A0 scanner it's very exspensive for us, ahah. I use Gnu/linux (Debian-like distro) but i'm not i geek, :-( However i know the potential of open source software. I thought immediately to a solution ad-hoc but i don't know if it's possible. The idea is about a big scanner builded with more (6/8). We thought to disassemble scanners and take only the parts needed to scan. I make us some questions. - It's possible to control more that one scanner with a tool like SANE? - If yes, it's possible to build a single scanned image from the scanned images of each machine, in real time :-) - If we try to make the scanner on lan an then take each scanned image and build one big images? We need one pc for each scanner? - More and more :-) I am asking a bit around and seemed a good idea to also ask the community of SANE. I hope the this idea can make some step to our goals. Bye bye. 1. the optical package of each scanner cannot be placed end-to-end and get a complete scan, because there is some dead space for packaging or mechanism on the ends. so now you have to stagger them, and then have a staggered calibration strip. correcting skew and adjusting height will be excercises in very precise machining. 2. you will have to have much larger and very rigid guides and carriage. 3. you will have to have a much larger motor, or convince the series of motors to move at EXACTLY the same rate, or some of them will be dead weight (very difficult to do if they have independent controllers) 4. you will have to multiplex all those streams of data, probably causing dataloss or motor stoppage/backtracking when the pc cannot keep up. as you can see, software is the least of your problems :) i suggest that you change directions. build a very square and sturdy moving platform, and scan with one scanner, using multiple passes, shifting the work one width left each time. you would have to stitch the pieces together afterwards, but that will be easy. allan -- The truth is an offense, but not a sin Depends also on the resolution you want to scan, for low resolution try a photo camera. For higher resolution, check if your file size get you in problems. 300dpi A4 colour 8 bit is about 25.5Mbyte, A1 is about 200Mbyte -- m.vr.gr. Gerard Klaver

Hello Gerard, nice to meet you! I'll send you my sources ASAP. I hope, you'll like my resource management: - sane_init() doesn't open every device at startup - no device needs to allocate a 64KB scsi buffer - sane_read() doesn't wait for the whole image to be read - sane_read() polls for `cancel' While the device handling issues aren't so important on a desktop with a single scanner, the `no-wait' and `cancel' things have been major pain reliefs for me. And most surely you will like my color scans: my scanner just tells me, _which_ color it has sent; hence no more sophisticated guessing algorithms, no more huge color permutation tables, and no more restrictions to preselected resolutions. Just pick a line, and if the scanner says `red', distribute it to the red bytes. This change would save you many hundred lines of code. Unfortunately, you can't call this an `obvious bug fix'. So don't do it, unless you can test it for all supported scanners. Here is my offer: you tell me, which scanner models you have your hands on. Then I can try to include one of them into my backend. If we're lucky, it'll work, and we can build an enhanced new backend at least for the scanners we own, leaving the old drivers untouched. -- ralph I still own the Relisys Scorpio Super 3 VM3575 and the PRIMAX JEWEL 4800 VM356A For the VM3575 the color line sequence was different depending on the resolution of the scan, see also my gkall.hobby.nl/notes1.html page for some test images.

It makes no sense to put the device in broken mode at startup. 2) Unsupported modes should not be listed. Why whould you even list options/modes that aren't supported by the backend? Nobody wants a SANE_STATUS_INVAL so nobody will set an unsupported mode anyway. Any modes not supported should be removed from the options. If your sane_control_option didn't give an error then that mode should be considered valid and usable setting.

[sane-devel] Accessing a scanner for a different reason
A sheetfeed scanner seems the best device to use (after removing parts). Depending on your specifications, tests with a webcam can also deliver enough information (remove the lines with data you don't need). A modified xcam backend is maybe also usable. On Thu, 2007-08-09 at 09:35 -0400, m. allan noah wrote: the problem here is not sane. infact, sane is not all that useful to you, as it is designed as an interface to setup a wide variety of parameters on 2-d scan, and aquire an image occasionally. you would be better off probably writing a stand-alone libusb program to aquire the data. your big problem is hardware. every manufacturer does something different in terms of the control language. cheaper units typically rely on the host computer for many functions, and feature a very low level command set (lamp on, move head 1 step, read 1 line, etc). more expensive machines have higer-level commands which rely on the cpu in the scanner (accept scan params, scan) you need to give more data about the size of read-head you need, the bit-depth, and your intended use, before anyone can suggest a particular model of scanner. allan On 8/9/07, Justin Rosen rosen at nanotoon.com wrote: Hello! I've recently stumbled upon the SANE libraries in an effort to gain access to a scanner. What I would like to do, is be able to read from a scanner, but not to create an image, but instead to pull RGB data from a single line of scan. Meaning I only need a scan size of 1 pixel x width of scanner. Also, I don't necessarily need the flatbed itself. Is it possible with SANE to access a scanner that has been taken apart? I essentially need the RGB values of the scanning head in realtime (I'm not sure what the terminology is for the portion of the scanner that actually gets color values). So imagine the scanner as a color sensor constantly pumping out an array of RGB colors, where the array size is the width of the scanner. I'm completely new to the SANE libraries, I've read the SANE Standard and compiled the SANE libraries and I'm stuck on the fact that I think the scanner I purchased is broken, so I'm at a halt for the moment, but thought I could get a little more insight on my issue. I thought my idea above could be possible using SANE for a few reasons. If I were to write a front-end that used a scanner to scan an area of 1pixel x scanner width per frame, and to continually scan frames until I told it to stop, I could receive RGB data as fast as the scanner could scan (hopefully real-time). If this can be done, great! I need to really figure out how to write the front-end! The only problem I see is that I'm hoping to take the scanner apart and use just the sensor to pull data from. I noticed that some of the SANE calls may fail if the SANE_Status is SANE_STATUS_COVER_OPEN, which leaves me to believe I won't be able to take the scanner apart and just pull RGB data from the scanner head. If anyone can answer any or part of my questions or point me in the right direction it would be greatly appreciated. Thanks for your time.

The changes to the fujitsu backend to support hardware jpeg were more extensive than i would like, but the changes to sane.h and scanimage were actually quite small. basically, sane.h just got SANE_FRAME_JPEG added to an enum. scanimage had a fixed-size array of string names for each frametype, and was using that array in two places to print informational messages. if it got a frame type that was off the end of the array, bang! so, i just added JPEG to the end of the array. then, just to be sure this would not bite the next programmer, i added a little ternary test any time we look in that array. instead of walking off the end, we print Unknown. my observations: if a backend sends a 'standard' frame type like RGB, and then sends a jpeg (or other unknown) frame, a proper tiff or pnm header and data will be written, and the additional frame will be appended, corrupting the image. if a backend sends those in reverse order, there will be no tiff/pnm header, because scanimage only sends those on the first frame of a known type. the data will consist of all the frames in order received. I would like to get some opinions about more complex scanimage modifications before i move on to scanadf. namely, should scanimage ignore these new frame-types, instead of putting them in the output? in that case, it would require another format option besides the ones we have now (tif/pnm) perhaps 'raw'? i personally would find a raw option useful for debugging the standard frame types too... comments? allan -- The truth is an offense, but not a sin I agree, adding a raw mode is useful for debugging. -- m.vr.gr.

[sane-devel] Additional frame types in Sane 1

I have been contracted to extend sane to support this capability. I can keep the modifications private, or i can try to get them included in sane proper (which i prefer). Therefore, I have reviewed the sane-devel mailing lists for the past several years, and tried to come up with a plan based on those discussions. Many of them center around Sane2, and proposals such a Mime or Textual frame-type determination. Given the speed at which Sane2 has moved, (most of these discussions are 5 years old!), and the relative complexity of those approaches, i am suggesting a more trivial alternative, specific new frame types. In all, i found mention of only 5 additional types of data sane does not handle well: JPEG, IR, ICC profile, EXIF data, and compressed TIF (G4 fax). Really, it seems like only the first three get repeated mentions in the archives. I dont know much about ICC, so my proposal is therefore quite simple. Rather than continue to wait for sane2, i am prepared to extend sane1 with 2 new choices: SANE_FRAME_JPEG and SANE_FRAME_RGBI. I would try to leave enough framework for others to add ICC and FAX support. yes, this will require that a front-end would have to be updated to understand this type of data. I can extend scanimage and scanadf (though i probably wont support all the possible conversions). it will also require (in the case of compression) that the front-end be able to deal with variable length data. comments, requests, flames? :) allan -- The truth is an offense, but not a sin Nice, SANE_FRAME_JPEG option is usefull for xcam, variable length data, for some devices a larger buf size is enough (scanimage -B or xcam -B option), i don't know how much effort it will be to extend xcam, but it sounds interresting. -- m.vr.gr.

Once compiled, problem is fixed. This is also an issue with the Plustek backend, reported by various Ubuntu and Gentoo users. As already stated by PhobosK, the problem is the kernel option CONFIG_USB_SUSPEND. This in deed is needed for laptop users. It is currently marked as experimental but already used by various distros. I think the problem really is, that libusb does not know anything about that suspend stuff and therefore we have more or less no possibility to wakeup the port, where the scanner is connected to. One thing that could be observed: In all cases, scanimage works fine - guess this is because it never closes the port until the scan process is done. Any ideas around?

[sane-devel] sanei_usb_open() and multifuntion devices
On Wed, 2006-09-13 at 13:29 +0200, Wittawat Yamwong wrote: Hello, I think that how sanei_usb_open() collects endponts is not correct. It loops through all configurations, interfaces and alternate settings and takes the first bulk in, bulk out and interrupt endpoint it found. This works only for some special cases and it is likely to fail for multifunction devices, e.g. Smartbase MP360 which has endpoints for the scanner function in the interface #1. I would propose that sanei_usb_open() accepts two additional parameters specifying an interface number and an alternate setting. These parameters can be omitted (e.g. set to -1). In this case the behaviour described above is valid. If the parameters are given, sanei_usb_open() must use only the endpoints belonging to the specified interface. There is also an issue with sanei_usb_set_configuration(), it simply doesn't work this way because setting new configuration will succeed if and only if there is no interfaces claimed by any driver. But the function takes the device number returned by sanei_usb_open() as a parameter and, unfortunely, sanei_usb_open() implicitly claims one interface. We have chicken and egg problem here. Solution: sanei_usb_set_configuration() have to take the device name instead of the device number as the first parameter. If I understand correctly, sanei_usb_claim_interface(), sanei_usb_release_interface() and sanei_usb_set_altinterface() are useless because sanei_usb_open() already claims an interface for you and sanei_usb_close() will release it afterward. Why does one want to claim another interface while he cannot use its endpoints through sanei_usb functions? Regards -- Wittawat Yamwong Hannover, Germany I use them for my stv680 backend, one problem i had after some updates (sane, libusb,kernel) was that setting the configuration didn't work anymore. Disable of the set_configuration solved it for me at that moment. If setting the configuration is needed for other devices, i don't know at the moment if some of the webcams i have need that. The above lines from some earlier email this year. I think a table generation with the selectable values for the configuration, interface and altsetting and then choice which values are needed will probaly solve some of the present problems when selecting a device and perform a bulk read. Depending on the function of a (for example) webcam (image size etc) selecting a different altsetting for reading (packet size) data should be possible (or an option which will be implemented later) Some usb devices have also for one altsetting 2 bulk read in endpoints to make it more complex. I don't know if somebody already made some code for these proposals and did some testing or has some other comment but i think a update for these 2 functions is an improvement (sanei_usb_open and sanei_usb_set_configuration) -- m.vr.gr.

I'm having some troubles with the tiff header: i'm using stiff.c I found in the backends' package to write the header of the file. The problem I'm having is that the tiff file is practically malformed (test opening it with the gimp). So i hijacked the stiff library and put a fprintf and exit right after the header is created. Here's what i get for the same page from the original scanimage and my code: scanimage width 5056 height 9000 depth 8 resolution 600 my code width 5399 height 9000 depth 8 resolution 600 doing a binary diff on the two headers i realize that (of course) they are different (same size though). I cannot really understand the problem as the stiff code is untouched and my code is practically equivalent to test.c My question is: why does my code get a different width than scanimage as we are both using data from sane_get_parameters()?

[sane-devel] interface sane-backens to bioapi
Hello, The question is of anybody ever has looked to the possibility to interface a SANE Backend with the BIOAPI see http://www.qrivy.net/~michael/blua/ for some information about BIOAPI. Currently i am working on a authentec fingerprint scanner backend. See http://gkall.hobby.nl/authentec.html for the AES2501, no working backend yet, but some scanning is possible with drivers mentioned below the Drivers links. First step is to get some image reading with xcam -B after that to see if a interface to for example BIOAPI is possible. With regards, -- m.vr.gr. Gerard Klaver

Oh! as a short term fix, rather than adding a new sane_frame type, the backend can extract the compressed data, convert to raw bitmap. then frontend can convert to any compressed format it wants. this is not as efficient as keeping the compressed version the entire way through, but it works now. dell networked scanner backend works this way. Well that stinks as you lose a lot of detail with the lossy jpeg decompression. even worse, if you are running the thing over the net backend, you convert to huge bitmap just before you transfer it over the network! Maybe let's add the JPEG frame type rather soon (even in SANE 1) and let's add an IR (infra red) frame specification on the way as good film scanner deliver for dust and the-like removal. agreed. though i would think we would need to make a well-known option like 'compression' or 'format' that such backends would have to implement, with the default being 'bitmap'. these backends would then 'unjpeg' the files before passing to frontend, and existing frontends will continue to work. then the user must manually set the option to something other than 'bitmap', if he knows his frontend supports this. SANE2 could require that the frontend support jpeg, and that could become the default for the 'format' option. allan Yours, Also for webcam devices the jpeg option is a welcome feature, devices like pac207 and sq930c/b support jpeg (and many other webcam usb bridges). -- m.vr.gr.

[sane-devel] sanei_usb_read_bulk: problem in handling of NAK
On Fri, 2006-05-26 at 22:52 +0300, Lauri Pirttiaho wrote: Hello, I have encountered a problem with bulk read that might benefit from some change in sanei_usb. This problem becomes visible in a fast machine like AMD64 and seems to have been seen in Avision backend and now in cs3200f. When using libusb method in sanei_usb the behavior of sanei_usb_read bulk seems to be that in responese to NAK (errno -ETIMEDOUT, strerror saying Resource temporarily unavailable, which means the device can not temporarily provide more data) the sanei_usb_read_bulk calls usb_clear_halt and then returns SANEI_STATUS_IO_ERROR. Now because of the usb_clear_halt there is no longer access to the errno so this particular reason for the IO error can not be distinguished from others after sanei_usb_read bulk returns. The solution in Avision backend seems to be that the errors from sanei_usb_read bulk are completely ignored and the function is called repeatedly until all data has been read. A temporary solution but maybe not the best one. I would propose changing the behavior of sanei_usb_read bulk so that in the case of NAK (resource temporarily unavailable) the size is returned as 0 and the return value is set either to SANE_STATUS_GOOD (read OK, just no data at this moment) or SANE_STATUS_BUSY (device can not respond right now). Both will work even though probably the latter one is more in line with the meaning of USB NAK in this case. With best regards, Lauri Pirttiaho Oulu Finland It seems i get for my sq930x SANE webcam backend (under development) the same errors. But when i do a init and read images with the MS driver and then a reboot (Linux) and start my sq930x backend i don't get that sort of errors but can do bulk reads with no problems. -- m.vr.gr.

That makes more sense. I guess I'll disable 2400 dpi to make sure the error doesn't occur. 1600 dpi seems to work OK. Ok. I've replaced the 2400 DPI resolution with 1600 DPI in CVS. Oliver, did you receive my previous post in which I've tested almost all possible combinations of resolution/scan mode/bit depth? Yes, but your mail got buried under some other mail ;-) The aspect ratio (=real resolution) is wrong in all but a few lineart modes. And halftoning was (at the time I've tested it) completely broken. Lineart and grayscale should be fixable. The aspect ratio is correct as far as I can see - it's rounded up to be dividable by 8, as each pixel uses one bit and the smallest unit to request is one byte, i.e. 8 pixels. My guess is that 1600 DPI works fine for both lineart and grayscale, so the only remaining problem is 3200 DPI in lineart and grayscale. Currently the deinterlacer is used for grayscale but not for lineart, it seems that both settings have to be adjusted. Can you send me example scans for 3200 DPI for a lineart and grayscale scan? As for halftoning: I've no idea how to fix it. If the windows driver doesn't offer it there's a good chance that the scanner doesn't support it at all. I guess it should be disabled. PS: will be 2400 dpi enabled in the future? And why does the windows driver allow 2400 dpi but not 1600? You'd have to ask the epson guys. My guess is that the scanner scans at 3200 DPI if 2400 DPI is requested and the decimating to 2400 DPI is done in software. It could be done in the snapscan backend as well, but I'm not sure if it's worth the effort. I guess the better choice (in terms of image quality) is to scan at 3200 DPI and rescale the image in gimp. /Oliver

[sane-devel] [ANN] Unpaper - post-processing scanned book-pages
On Wed, 2005-03-02 at 16:03 +0100, Jens Gulden wrote: Hello, unpaper removes black edges and other photocopy artefacts from scanned images. It also deskews book pages (auto-rotates them to a straight alignment), and centers them on the sheet. Old photocopies can become well-readable PDFs again. Available at http://unpaper.berlios.de/. Hope it's useful. Enjoy, Jens From the Readme: -- unpaper is a post-processing tool for scanned sheets of paper, especially for book pages that have been scanned from previously created photocopies. The main purpose is to make scanned book pages better readable on screen after conversion to PDF. Additionally, unpaper might be useful to enhance the quality of scanned pages before performing optical character recognition (OCR). unpaper tries to clean scanned images by removing dark edges that appeared through scanning or copying on areas outside the actual page content (e.g. dark areas between the left-hand-side and the right-hand-side of a double-sided book-page scan). The program also tries to detect disaligned centering and rotation of pages and will automatically straighten each page by rotating it to the correct angle. This is called deskewing. Note that the automatic processing will sometimes fail. It is always a good idea to manually control the results of unpaper and adjust the parameter settings according to the requirements of the input. Each processing step can also be disabled individually for each sheet. Input and output files can be in either .pbm or .pgm format, as also used by the Linux scanning tools scanimage and scanadf. Conversion to PDF can e.g. be achieved with the Linux tools pgm2tiff, tiffcp and tiff2pdf. -- (It's a small program with 1 single source file only. Almost too small for being an open-source project on its own. If you have ideas to integrate it into other Linux scanning/graphics projects instead, please let me know.) Hello Jens, My proposal/idea would be te place it in a sane-tools package. This would be a new package with for the time being only the unpaper program. Also if there are other tools related to scanners or webcams the have a place to be kept. For example the lprof package see: gkall.hobby.nl/sane-lprof/sane-lprof.html And maybe a place to keep the icc profiles from scanners? Other packages? In this way also the package can maybe be used as a plug-in for some scanner frontend programs?
