[sane-devel] Epson 3490 and Slide/Negative scaning.
Hello, I'm looking for a scaner (rather inexpensive one) that could scan slides and negatives (mainly BW) under linux. Curently I have a Microtec 35t+ which is a dedicated film scaner, which works quite nice with vuescan but has problems (at least with Advansys SCSI controler and 2.4 kernels, will see how will it work on a 2.6 kernel and Adaptec controler) with sane. But since I'm scaning mostly BW negatives and the negative adapter is broken.. I'm thinking about a new unit. Epson 3490 is inexpensive scaner and is listed on the sane page as beeing supported (as good). The question is.. does sane supporr olso slide/negative scaning, and how good this scaner behaves under Linux... Does anybody on the list had any experience with this scaner and transparencie scaning? My regards. -- Rados?aw Rurarz Warsaw Poland GG: 7249330 -- Swietnie zdjecia do poogladania http://link.interia.pl/f192b
[sane-devel] Canon LiDE 30 FC 5 hotplug question
I've updated my machine from FC4, in which I did not try Xsane (etc.) to FC 5. When I plug in my Canon LiDE 30 USB scanner and fire up Xsane, it announces that it cannot find a scanner. However, if I leave it plugged in, logout, and log back in, then Xsane finds the scanner and every thing works swimmingly. Under FC3 it does not seem to matter. Hot plugging the scanner works fine. Can anyone shed light on why the hot plug capability is not working for FC5? I did notice the hot plug scripts are gone but I assumed that was because UDEV (or HAL, or something else) was suppose to take care of this. Any assistance or enlightenment would be appreciated. Thank you, -- --R /Linux, and Open Software, an alternative./ Registered Unix http://counter.li.org user #409453

Sane does not itself provide OCR, but calls gocr to produce a text file. At level 0.3.5, gocr supported output formats ISO8859_1 TeX HTML UTF8. It would probably be better to call these character encodings rather than formats. http://jocr.sourceforge.net (Note the j.) My experience with gocr is that the text file requires human review and correction to be usable. Commercial OCR does better but will never be 100% accurate. When you say produce XML, do you mean produce a valid marked-up document according to a given DTD? Roger

I'm working on getting raw data (without calibration, 16-bit samples) from it but don't have too much time currently (it requires some further investigation). There is potentially an issue with black level calibration. I have a patch but I'd have to check if I got that right. Let me know if you have such problems. -- Krzysztof Halasa
[sane-devel] Nikon CoolScan IV and next sane release
Is there any chance the next sane-backends release will include the patch for supporting CoolScan IV (LS-50 ED)? This patch was proposed before the current release was prepared and it was never changed/updated. The patch still have some problem, but it works for colour negative film. Bye, Giuseppe
[sane-devel] Preparation for sane-backends release 1.0.18
Hello! I'm preparing the pixma backend for inclusion in the next release of sane-backends. Patch against cvs from 2006-04-25 can be downloaded at http://home.arcor.de/wittawat/pixma/pixma-sane.patch.gz It would be kind if a SANE developer could check the source code if it compiles on other platform than SUSE Linux 10.0 and if it correctly follows the SANE backend writing guideline. Thank you in advance. Regards -- Wittawat Yamwong Hannover, Germany
[sane-devel] Wrong colour scanning with HP 7400c

Or does it happen for scans in the middle of the page as well? It does not happen with a smaller region. However, I can reduce the scan by so small an amount that the yellow stripe will still show up just smaller. But I can also see that the yellow stripe overlays the picture, so it is not some plastic on the side or similar, it is actually induced by the backend. BTW, there is also a tiny green stripe about 1/5 of the width of the yellow stripe. Hm, maybe then something is or got wrong for the 7400 calibration. Anything I can do for the calibration? The calibration is done (for scanners requiring this) by the avision driver. Most probably some regression (e.g. support for other calibration data layout) was introduced since I know it noce works perfectly for the HP 7400. You can either try older versions and tell me which one work, read the svn history like svn log http://svn.exactcode.de/sane-avision/trunk or the code directory to find out where it goes wrong. I'll take a look in some days when the important stuff from my desk is done. Where can I find the older versions? -- Regards, Erik P. Olsen.

[sane-devel] adding stv680 backend to cvs
Hi, I have stil some memory leakage errors (with valgrind xcam -B) when using my stv680 backend. But i think its ready for adding to SANE CVS so it can get a bigger audience and more testers. Homepage http://gkall.hobby.nl/stv680-aiptek.html I have placed the files and a logfile on http://gkall.hobby.nl/downloads.html Files: stv680.c, stv680.h stv680.conf.in, stv680.desc, sane-stv680.man log-valgrind-stv680.txt The used font_6x11.h file is the same as used in sane-frontends/scr Before adding to cvs i like to know if there are comments/remarks.

[sane-devel] Epson 3590 Scanning issues
I've got an Epson 3590 that I have scanning, but it does not scan the entire page. I'm using Fedora core 4 and sane-backends 1.0.17. I've also tried it with 1.0.16 with the same results. My command is: scanimage -d snapscan:libusb:001:002 --format=tiff --resolution 200 /tmp/image.tiff It says that it's using the max X and Y cooridinates, which comes out to about 8.5x11, but I'm not getting that on the image. The image is cutting off the lower 1 - 2 inches and about 3 inches on the right side of the page. I tried increasing the X and Y values, but they will not go beyond 216 x 297 (i believe it's 297. It's something like that). I'm needing to scan the entire 8.5 x 11 page and save it to a tiff file. Any ideas or suggestions would be greatly appreciated.

There is no easy way to fix that. What helped Henning was to clean the calibration area. The backend is currently not able to cope with (much) dirt there. You can get a distorted raw scan of the calibration area by enabling debugging. That should give you a file named black_white_shading.pnm. When scanned at the higher resolutions(=600dpi), it should have vertically striped area(s), but only very few dirt particles. I have not figured out how to clean the calibration area. There was no instructions that came with the scanner. Is there some guide to how to take the parts apart? There is one possible plastic hook pair on the bottom, but it looks like a manuafacturer-only access point, requiring a special tool. Also a few slices across the image, possibly from a jerk of the head at that point in the scan. On the whole, an acceptable image. Did this happen because the scanner moved the head back to restart at the buffer overflow position? If that is the case, i need to do some more tuning on the acceleration tables. That should definitely not happen(Though it is no reason not to put the code into sane-backends). It happened at 10 cm of an 11cm postcard scan. The scanner does quite a bit of shuffling, and I thought it might be related to that forward/reverse timing in the shuffle. HP2400: no change, not working. Not working as in refuses to move head/deliver useful data or as in provides a 2400x1200dpi image? For the latter case i do have a patch, enabling a nearest match interpolation. The head never moves. It goes into a calibration at the beginning, and never completes the calibration correctly, and then times out with a question on the lamp: [genesys] genesys_warmup_lamp: warmup timed out after 46 seconds.
