[sane-devel] sane and xsane-win32 crash
Odd behaviour with Xsane-win32 build: sane-1.0.6 on a linux machine with a scsi Tamarack 6000 scanner. On the linux side xsane works (like xscanimage, scanimage, etc) saned configured as suggested in inetd.conf, access granted accordingly xsane-win32-0.86 installed as instructed on a Win95 machine. running xsane results in it crashing and it creates a stackdump in a file : Exception: STATUS_ACCESS_VIOLATION at eip=6108179C eax=10061DD0 ebx=FFFC ecx=3374 edx= esi=10065000 edi=10064FFC ebp=00B1F63C esp=00B1F630 program=C:\SANE\XSANE.EXE cs=016F ds=0177 es=0177 fs=3BC7 gs= ss=0177 Stack trace: Frame Function Args 00B1F63C 6108179C (10061DD0, 10061DD4, FFFC, 6108CFD8) 00B1F66C 004669B8 (10061D74, 0004, 0011, 00B1F694) 00B1F69C 0046783D (10061D74, 00B1F798, 10061D74, 00466BBE) 00B1F6BC 00466BA2 (10061D74, 00B1F798, 00B1F6FC, 00466607) 00B1F6FC 00466611 (10061D74, 00B1F794, 00B1F73C, 0046703F) 00B1F73C 0046704C (10061D74, , 004665BC, 00B1F79C) 00B1F7AC 00464F37 (10061D58, 7FFF, 00B1F7DC, 0058092F) 00B1F7FC 00465666 (0046B448, , 00B1FA8C, 00462076) 00B1FA8C 00462089 (0001, 10060B18, 78037118, 00B1FAD8) 00B1FBCC 0046227C (0001, 10060B18, 00B1FBFC, 00462452) 00B1FBFC 004629DA (0001, 10060B18, 10060008, ) 00B1FD88 6100401E (, , , 00B1FF68) 00B1FDB8 6100421D (00462444, , , ) 00B1FDD8 6100425C (, , , ) 00B1FE08 00467A3F (00462444, BFF7CC72, BFFC1470, 00B1FF78) 00B1FE38 0040103D (, 819F01FC, 0091, 6E617358) End of stack trace (more stack frames may be present) Logs on the linux machine simply show an accepted connect from the win machine, then saned says "Exiting" If saned is run as saned -d128 as suggested for debugging, no debugging information is printed at all. But xsane on the windows machine does not crash, even more, it works fine. Only thing not tried yet is to start saned -d128 from inetd... Please, if anyone has a suggestion it would be most welcome.

[sane-devel] only selected backends
With the latest sane-1.0.8, how do I configure it only to compile and install the backends that I want, instead of all (default) ? I tried configure --without-v4l for example (because I have a DVB card which also uses v4l for it's TV display and sane annoyingly looks for v4l and loads the modules for DVB even if not wanted), but configure still reported "enabling v4l backend" and v4l support was installed and probed every time I started a scanning frontend (xsane) I also tried to edit backend/Makefile.in and from the define PRELOADABLE_BACKENDS = tamarack @NET@ and the running configure again, it still compiled and installed ALL the backends.

[sane-devel] sanetwain hicups
Just reporting some apparent bugs : sane-1.0.8 on a linux machine, saned running. latest twain_32 installed on a win95 system. sanetwain (dl yesterday) tamarack 6000C scanner. I don't know what resolution is used for preview by it's windows software, xscanimage or xsane. however: If in preferences, Preview is set to "use minimum resolution", sanetwain GUI always returns "Device busy" error. Same if resolution set to 100dpi in preferences. If in preferences, Preview is set to "Use the following resolution" and resolution set to 50 or 25 dpi, then sanetwain scans a preview, after scanning complete, it shows "Device busy" error, then, after pressing OK, the preview image appears correctly in sanetwain preview area. Changing scanning resolution setting in sanetwain window, then changing scan mode will reset the resolution setting to the default 100dpi. all textboxes holding resolution in sanetwain behave annoyingly considering the following: - normally text is alligned to the right. - a click in the box to edit the text will delete the "100 dpi" text and replace it with only "100", but now it is aligned to the left. - trying to click and select a digit which to change cannot be easily accomplished, since the text contents of the box is changed upon clicking into it. Suggested behaviour of these textboxes: - keep a consistent aligning of the text. Do not change aligning when editing the textbox - keep entire text in the text box when editing. Changing it upon edit confuses the user. - handle the contents of the textbox to read the entire text in it when changed, consider only the first sequence of digits as the resolution. Convert it into a number, check to be in a valid range. place it back into the box and add "dpi" after it (since it will always be dpi). Also, the scan resolution textbox retains focus (cursor in it) if there is a mouse click outside it, on the preview, or options tabs. I managed to make focus leave it by trying to change scan mode. = ing. Andrei Boros Centrul pt. Tehnologia Informatiei Societatea Romana de Radiodifuziune __ Do You Yahoo!?

[sane-devel] xsane-win32 error handling
Thank you, Oliver, I followed your advice and installed sane-1.0.8, configured and started saned, and tried again. - first result was the same. (stack dump) - after digging a little more, I found in the logs that tcpd reported "file /usr/sbin/saned not found". (my inetd.conf line contained /usr/sbin/tcpd saned) I changed it so it contained the full path name to saned, and it worked. I'd suggest to add some more error handling to the network communication layer in xsane, so that connection loss, inability to find a valid saned at the other end does not crash xsane Also, I'd suggest to the maintainer of saned.man the following: I used the example shown for inetd.conf using tcpd directly, but it did not work because tcpd expected to find saned in /usr/sbin, while it was installed in /usr/local/sbin. I'd suggest to change the example for this case to reflect this by using the full pathname for saned. Great frontend, Oliver! = ing. Andrei Boros Centrul pt.

[sane-devel] Client only installation of sane
How can one install a client only installation of sane? No backends needed, as all scanning would happen over the network. saned is not needed Possibly libraries and headers of sane would be needed to compile other frontends (not sure, so far I always compiled frontends having sane-backends already installed).

[sane-devel] sane port number
saned is recommended to be configured on TCP port 6566, called via inetd. I assume this is the port reserved for sane as a network service. Extract from http://www.iana.org/assignments/port-numbers === # 6559-6579 Unassigned === I have a small question : Will sane developers apply for an assigned port number for sane network service on port 6566 at IANA?

[sane-devel] Plustek UT24 w/transparency advice
I am looking forward for an upgrade and the old Tamarack I have is clearly not enough anymore. Prospecting the market in Bucharest gave me 2 choices. Sane support reduces this to one. I was looking for a 1200x2400 dpi optical, USB (maybe SCSI), with transparency adapter. The answer came either as UMAX Astra 4500 (transparency adapter is an extra), but this is apparently not supported by sane and the vendor is unfriendly. The other answer was Plustek OpticPro UT24. My research through sane supported scanners showed that it is supported reasonably well. However, there is a potetial issue, regarding scanning of negatives. If those using this scanner (Plustek UT24) can give me any advice on aquiring it or not, pluses and minuses for it in it's future use, I would be most grateful. Thank you. = ing.

[sane-devel] Tamarack 6000C slooow scanning
Hi, I already put this question when sane was at version 1.0.3 Yesterday I upgraded to sane-1.0.6 and tried again. I have a Tamarack 6000C scanner (branded ESCOM, but sane-find-scanner sees it as Tamarack) with a g_NCR5380 ISA SCSI card. As with previous versions of sane, the scanner works, but it works so horribly slow that scanning a full A4 page at 300dpi greyscale takes over an hour!!! The stepper motor moving the sensor cart moves about one step per second instead of a continuos rapid succession of steps. Please advise me what can I do to improve scanning speed. Otherwise, system is much more stable then when scanning in windows (where it takes about 3-5 minutes for a 3 pass 300dpi A4 full color page). All functions work besides the speed. System is a Slackware 7.0 with 2.2.19 kernel. I checked and the SCSI buffer is set at 128k. (found it in the docs). = ing. Andrei Boros Centrul pt.

A glance at the kernel source (g_NCR5380.c) tells a lot : USLEEP_POLL = 1 USLEEP_SLEEP = 20 USLEEP_WAITLONG = 500 I'll try to play with them a bit. = ing. Andrei Boros Centrul pt.

I had kenel lockups sometimes while playing with these > values. I tried to play with these, first of all using the suggestion for Mustek from the link you told me, then I played around with other values as well, also I commeted out USLEEP. The results yielded a small increase in performance, but far from satisfactory. Now the scanner sensor moves continuosly for some X cm dependent on USLEEP_POLL and USLEEP_SLEEP, then waits a certain time, longer (1.5-3 times longer) then the time it took for the motion. With the settings suggested for Mustek, it moves about 5cm first, waits, the moves about 2 cm, waits again and repeat in 2cm increments. With USLEEP commented, the behaviour is similar. Playing around with these values I could only increse or decrease a little the distance of one continous move, with a similar increase of the waiting time. The machine was never dedicated completely to the scanner, not even with USLEEP commented. I started xscanimage from a remote X server and a ping in another window. It never lost packets. top command showed on average >80% idle Overall, there is a slight improvement of speed (at least for the preview), but still more the 3-4 times then under windows. Looks like I'm stuck with M$Win for using this scanner. Thanks for the suggestions. = ing. Andrei Boros Centrul pt. Tehnologia Informatiei Societatea Romana de Radiodifuziune __ Do You Yahoo!?

[sane-devel] Tamarack : scanning speed
I tried sane 1.0.4 yesterday (and an older version a few months ago) with a dissapointing result. My setup is : Pentium 200MMX, 64MB, NCR5380 SCSI controller (came with the scanner) and a Tamarack 6000C scanner (actually branded ESCOM, but reported as Tamarack on SCSI bus). System is Slackware 7.0, kernel 2.2.19. The NCR5380 which came with the scanner uses port access (0x240) and DMA, no IRQ's. It is detected by the SCSI driver and with the scanner on, it detects the scanner, no problems. sane-find-scanner finds the scanner correctly on the SCSI bus. Trying to use xscanimage to scan an image, let's say 300dpi, color, a full A4 page I got an excellent result, but it took 5 hours. Usually, a scan (300/color) with the windows drivers takes about 5 minutes. xscanimage scanned it in 5 hours. I watched the scanner sensor, it moved a step about one a second, instead of a continuos pass. I read in the manuals about SG_BIG_BUFF and set it before compiling sane, and rebuilt the kernel and modules before using it, as I remembered it from the previous time I tried sane, an older version. I got the same result then, although I didn't have the patiance to let it finish one scan... Changed the SG_BIG_BUFF then, with no result. Same with sane-1.0.4 If anybody can please suggest something to improve scanning speed.. Thank you. = ing. Andrei Boros Centrul pt.
