[sane-devel] [PATCH] undefined symbols in the qcam backend on GNU/kFreeBSD
Hi,
Please find below a patch to the qcam backend to fix undefined symbols
at runtime when dlopening the symbols on GNU/kFreeBSD (GNU libc with a
FreeBSD kernel).
This platform uses a GNU libc, so sys/io.h is available. However the
check in the source code is done on __linux__ and not on __GLIBC__.
I would even change the line to
#if defined(HAVE_SYS_IO_H) || defined(HAVE_ASM_IO_H) || defined(HAVE_SYS_HW_H)
but they may have systems where one of those is defined and the where
the associated functions inb and outb functions are not defined.
Thanks,
Aurelien

[sane-devel] require Hp2300C linux debug messages
Hello, Is there anybody here with HP2300c? If anybody have it can you please send me debug messages log that will come when you scan a document. Please send me that output of debug messages by enabling them by exporting first environment variables export SANE_DEBUG_GENESYS=255 export SANE_DEBUG_GENESYS_GL646=255 Regards, Parag.
[sane-devel] more medium definitions?
hallo together, i am searching for more medium definitions, especialy for negativefilm scans. i hope i am right here with my question. diafilm scanning works great but all my negative scans are verry green or yellow. i am using xsane with my epson 4990 photo unter debian testing. are there any resources to get mor medium definitions? i didnt find any in google and my eyes are not good enough to do my own. maybe someone can give me a hint how i get this green under control. thanks for sane... best regards robert grah
[sane-devel] Trust Office Scanner USB 19200
Hi,
I have a Trust Office Scanner USB 19200 which I submitted yesterday as not
supported. On IRC I was pointed an URL:
19:02 gekl paul_: check this email about your scanner
http://lists.alioth.debian.org/pipermail/sane-devel/2005-April/013431.html
This indeed more or less solved my problem. At least I can scan, only the
resulting image is mirrored. This can be fixed with xsane, but it would be
nicer to have it working the right way. To sum things up, I did the following:
Changed the following in backend/niash_xfer.c
{Hewlett-Packard, ScanJet 4300C, 0x47b,0x1002, eHp4300c}
to
{Silitek Corp., HP ScanJet 4300c, 0x47b, 0x1000, eHp3400c}
and the same in tools/hotplug/libsane.usermap and recompile.
If someone wants me to do some more testing to get this scanner included,
please let me know.
Ps. I am not subscribed to this list.
[sane-devel] Microtek Film Scan 35
Dear SANE developers, I've got six years old Microtek Film Scan 35 which nobody cares of at my work. Unfortunately I seen the mark unsupported at SANE web site. Small remark made me confused [ http://www3.sane-project.org/sane-mfgs.html ] : FilmScan 35 USB unsupported Probably unsupported. See link for details unsupported (2005-12-18) ? - What does Probably unsupported mean? Both links gave no hope of course... If it means, that the scanner is somehow supported, could you explain how to make it working at my Linux box? If it means, that the scanner is not supported, I'd like to know how much man-hours it would take to create some basic support. I have some free time, good knowledge of C and Linux. Could anyone to outline the procedure of creating (or extending) the SANE back-end? sane-find-scanner says there is a device with vendor/model as expected. xscanimage pretends there's no available scanner however. With the warmest regards, Andrei.
[sane-devel] Benq 5150C / 5250C users: please test
Hi all, I've added some basic support for the Benq 5150C / 5250C scanner to the snapscan backend. Anyone owning such a scanner is encouraged to test it and inform me of any problems. Ok, I did some testing with my BenQ 5150C. My first try was in 300dpi color mode (because this was default). There are no color stripes anymore. However, the scanned area was not very wide. Although the full available range ((0,0)x(216.0,297.0)mm^2) was selected in xscanimage. The resulting image had only 109 mm in width and approx. 145 mm in height (measured with millimetre graph paper) This is independent of selected resolution and colour mode. 'Gray' doesn't work. It still results in very distorted Images. When doing 'gray' with xsane there is a message box saying Backend sends more image data than it defined in parameters, after scanning in preview mode. 'Halftone' sends wrong colours, and sometimes the same patterns as gray. In xscanimage, preview crashes in this mode. Lineart however sends correct data when not selecting quality scan (at first glance, no further investigation done). At the beginning, I had some hangs, which required to hard reset the scanner, but this is not reproducible. At present the calibration algorithm for the 5150 / 5250 is unknown. The calibration data sent to the scanner is currently some static data which may or may not work for all scanners. I'm not a hardware developer. But if you need any data, be free to ask. But as my attempt to sniff on the USB-bus in Windows fired up the whole system and I could not scan anymore until the next reinstall of W2K, I won't do that anymore. Regards, Ben

This means that someone told us that this scanner exists but there is no obvious backend that could support it. But no in-depth analysis was done, e.g. which chipset it uses and if it could be supported by an existing backend. When I get a report about a scanner which is not in our lists yet, I usually list it with the comment Probably unsupported. If it means, that the scanner is somehow supported, could you explain how to make it working at my Linux box? If we knew some way, it would be documented in the lists. If it means, that the scanner is not supported, I'd like to know how much man-hours it would take to create some basic support. I have some free time, good knowledge of C and Linux. Could anyone to outline the procedure of creating (or extending) the SANE back-end? See SANE website, section Contributing. See also the archive of this mailing list for similar questions about writing backends. Bye, Henning

I assume if I use an existing backend as a template then I should still manage to create compatability with SANE. Looking at the documentation (SANE standard and others) on our website as well as the Contributing section may help :-) Please also send the output of sane-find-scanner -v -v, so we can add it to our scanner lists.

[sane-devel] dell1600n-net backend
Hi, I have written a driver for network scanning using a Dell 1600n MFP. It is implemented as a perl script and can be found here: http://www.jon.demon.co.uk/dell1600n-net-scan/ I am currently in the process of figuring out how to write an equivalent SANE backend. I have a couple of problems: 1. Hopefully trivial: I have written a dummy backend and sym-linked it to /usr/lib/sane/libsane-dell1600n-net.so. How can I get a SANE frontend to find it? 2. The Dell 1600n sends data back in CCITT Fax Group 4 or JPEG formats (for monochrome or colour scans respectively). To convert this to an array of RGB data will require converstion via an external library (eg: libjpeg). Is this extra link dependency acceptable for the SANE backends build? cheers, Jon == Jon Chambers = http://www.jon.demon.co.uk, 020 8575 7097, 07969 956575 =
