[sane-devel] Double-free following scan on ubuntu hardy 8.04 with epjitsu fi-60f
Hi, Julien BLACHE wrote: Gah, that damn crash reporter is getting in the way. Can you try to get rid of it? You have to set the env variable MALLOC_CHECK_ to 0, i.e., in bash export MALLOC_CHECK_=0 or in tcsh setenv MALLOC_CHECK_ 0 then you will get a proper backtrace with gdb.. http://www.gnu.org/software/libtool/manual/libc/Heap-Consistency-Checking.html If possible, use valgrind -v scanimage -d epjitsu to generate the backtrace, it will be more informative. regards -- jochen

Hi, I guess the bug is that in sane_close the scanner_devList entry corresponding to the open handle is destroyed, and later in sane_exit all scanner_devList entries are destroyed again. I guess in sane_close, the entry should be be destroyed, but only marked as free or so. regards -- jochen
[sane-devel] v4l device and colors
Hi, Maybe somebody will be able to help be, because I'm going insane here ;) I'm trying to build a music sequencer that would use color input form the camera to generate music (something similar to Bubblegum Sequencer). Sane looks like a best way to integrate my video4linux webcam input with my python program. The problem is that when Sane (both in form of the python library and xsane standalone program) show the camera input it's totally blueish - almost blackblue (something like blackwhite, but with blue in place of white). All the other video4linux programs show the real colors. Sane is also using video4linux, so I have hard time understanding why suddenly everything goes blue... Any ideas?

Does anyone have a good procedure for patching and rebuilding released ubuntu .debs to test upstream changes? Or a way to build new debs from sane snapshots at a particular revision? The originally reported platform (Ubuntu) is not my familiar source-based system (Gentoo). This is how you could do it in Debian [1]. Basic method for a package somepackage version 0.7.1-1 is as follows. (This does not change the version number, but that is explained in the documentation.): 0. Get the source package. 1. put somepackage_0.7.1-1.diff.gz somepackage_0.7.1.orig.tar.gz somepackage_0.7.1-1.dsc in a directory. 2.

[sane-devel] HP 5590 not working in 1.0.19
On Tue, Apr 29, 2008 at 3:06 AM, Albert Cervera i Areny albert at nan-tic.com wrote: ... I simply used 'scanadf -v'. Now I realize that there are much more options. Using scanadf -v --mode Color --source ADF --resolution 300 uses papers from ADF correctly. Sorry about the noise. However, I don't think the error in the simple scanadf -v case is normal... By default, the backend uses flatbed as the source. Thus if you start 'scanadf' in the way you did before, you should get endless scanning as scanadf will try until 'No documents in feeder' error (or any other) will occur. The 'No documents...' error won't be returned when using flatbed, which is obvious. Anyway, I agree, the error shouldn't be there. May I ask you to collect the debug information but with SANE_DEBUG_HP5590=50 set? The debug information will contain more details, including scanner firmware version. I suspect that it could be different from mine. Thanks in advance, -- Ilia Sotnikov

[sane-devel] hp4570c driver from modified hp5590 backend almost working
Hi Ilia, Those changes are not the only ones required... It was still failing. I have a patch file I will post here once I test the modes. Let me test all the modes (I only tested full color preview and scan). I also haven't tested the ADF connected to it. I may not get to testing it until later today, I have to dig out the ADF feeder. I do have a question for you: I called the 4570 a: Workgroup scanner But im not sure if it should be that or a document scanner (per your entries in the hp5590 driver for other scanners). Any idea which it would be? -- next part -- An HTML attachment was scrubbed... URL: http://lists.alioth.debian.org/pipermail/sane-devel/attachments/20080429/5fdff2dc/attachment.htm
[sane-devel] Success in modifying hp5590 backend to support hp4570: driver works!
In regards to the issue with dpi. That was too early in my debugging phase... I mis-read the dpi_x value and was thinking it should be 300 dpi for that entry.. turns out it a correct value. There was another change from my earlier posts that was needed to get it the driver working. I will test other modes and the ADF to verify it all.. So far I've tested full color scan and line art. -- Markham -- next part -- An HTML attachment was scrubbed...

Anyway, the whole product family - 4570/5550/5590/7650 seems to be different only in mechanics and available accessories. I could even suppose that we could add HP 4500/5500 to the list. 4500/5550 have ADF, 4570/5550 - APF. I do have a question for you: I called the 4570 a: Workgroup scanner But im not sure if it should be that or a document scanner (per your entries in the hp5590 driver for other scanners). Any idea which it would be? This name I've got from HP site, so it's their positioning. You could choose any name which is meaningful for the scanner. The names and corresponding core is informational and could even be removed. -- Ilia Sotnikov
[sane-devel] hp4570c driver from modified hp5590 backend almost working
I was incorrect on the 4570 having a ADF unit, after pulling hardware out of the closet I see its a 35mm slide unit that I had gathering dust. I'll hook that up and see if it changes any of driver responses. It also sounds like I should rename it to a document scanner to be a more accurate description. - Markham -- next part -- An HTML attachment was scrubbed...

With the TMA slide adaptor on the Scanjet 4570c does not work properly when : scan source = TMA negatives -- [hp5590] Top X (0) + pixels X (4292) exceedes max X 169 xscanimage reports: Failed to start scanner: Invalid argument In fact with the TMA adaptor in place even choosing: scan source = flatbed after you did a source=TMA causes the carriage to ram into the stop. You have to power cycle the scanner to be able to get a source=TMA to properly work. So avoid source=TMA, choosing source=flatbed even with the TMA adaptor plugged in will work fine. Evidently there is some problem with the source = TMA. source=flatbed line art, color, and gray = working resolution 100 to 2400 = working source=TMA negatives or TMA slide fails in all modes, ramming the carriage against the stop I will use VMware + wireshark again to monitor my WinXP virtual session and see what protocol is being exchanged when source = TMA. It maybe that I can fix the driver, but I suspect it will be more extensive changes. Let me look at what it takes to fix it. If it gets too involved I will submit the current patch with the caveat source=TMA fails, and work on fixing support for TMA later. -- Markham -- next part -- An HTML attachment was scrubbed...

Evidently there is some problem with the source = TMA. Hmmm, I've done little to no testing for TMA to be honest. One solution is to disable TMA completely until fixed, 2nd - get it working. Latter requires more work, former is more reliable. What makes me suspicious is that HP site mentions the model together with APF (Automatic Picture Feeder), not TMA. Could you shed some light on whether it requires to feed the film manually (thus it is TMA) or automatically (thus it is APF)? source=flatbed line art, color, and gray = working resolution 100 to 2400 = working Looks promising.
