[sane-devel] Error while setting the mode option of HP ScanJet 6200C
Hi All,
I have the following code to display my SANE options:
void sane_display_options(SANE_Handle handle)

=09num_options =3D index;
}
However gdb throws an error in the second strcmp. I cannot understand
the reason why?
The following is the gdb output:
(gdb)
409 if(strcmp(option-name,mode)=3D=3D0)
(gdb)
411 SANE_String mode =3D Color;
(gdb)
412 SANE_Status status_loc =3D
sane_control_option(handle, index,
SANE_ACTION_SET_VALUE,(SANE_String_Const*)mode,NULL);
(gdb)
413 if(status_loc =3D=3D SANE_STATUS_GO=
OD)
(gdb)
414 printf(Mode set correctly.=
);
(gdb)
416 if(strcmp(option-name,mode)=3D=3D0)
(gdb)
=20
Program received signal SIGSEGV, Segmentation fault.
0x42079408 in strcmp () from /lib/tls/libc.so.6
(gdb) p option-name
No symbol option in current context.
(gdb)
Can any one tell me what am i doing wrong here?
Thanks,
Mohit
[sane-devel] Re: sane-devel digest, Vol 1 #806 - 7 msgs
Hello, The test16.pnm picture you posted is perfectly fine (I'm using Imagemagick to see it). The trouble you get is related to the image viewer you use. After trying konqueror to display it, I saw the same artifacts you get. So it's a kde a bug related to 16 bits pictures. For the other bug -trying to scan outside usable area- bound checking is done. I think it may be a bug in scan area origin detection bug. Origin may be wrongly detected a few mm too much toward buttons side, so the scanning head goes to far. You may check it by scanning a triangle shaped paper, with one corner touching the very top of the scanning area. If expect that a few mm of it will be missing. You may also wait ~45 s after powering before testing. I think origin detection may fails if scanner isn't warm enough. When all debug is activated, the backend write debug pnm files containing data is scans. I'd like to have these: - search_position16.pnm - search_position.pnm - laplace.pnm - xsobel.pnm - ysobel.pnm Regards, Stef

problems: It cannot chown and chmod of /proc/bus/usb/001/003 which might be
my scanner device. (I think it should be 001:001). I don't always get this
You do need to get the permissions set on the right device.
In the procfs, the T: line identifys the device and provides information.
You do not have to guess in the sysfs either. This command
will list all the device numbers first, followed (in the same order)
by idVendor or idProduct (by manufacturer may fail because some do not
supply their name. idVendor and idProduct are required by USB specifications)
cat /sys/bus/usb/devices/*/{devnum,idVendor}
From the sane-project site:
Support for models 5200C/62X0C/63X0C connected to the USB require the
kernel scanner driver or libusb. See sane-usb(5) for more details.
Best regards,
Gerald

After reading, googling, and more reading, this is what I assume it is to be done in order to get the Scan working properly. However, I DO NOT get it working, so please let me know what I am doing so wrong. 1) Connect the Scanner 2) Get the firmware (a_file.bin) 3) Place the file.bin somewhere 4) Specify that path in /etc/sane.d/snapscan.conf just like it says here... # Change to the fully qualified filename of your firmware file, if # firmware upload is needed by the scanner firmware /home/me/e25.bin After that, is there anything else I should be doing? --=20 Best Regards, Mauricio Hernandez Z.

Janusz S. Bien schrieb: The original scans converted to DjVu DjVu looks interesting (http://www.djvuzone.org/). Thanks for that hint, I didn't know it before. Although the processing improved the images in some respects, in general the result seems to me less readable then the original. The dirty artefacts around letters are strange. Do you think they originate from unpaper's processing? I placed an unprocessed page from your djvu-file to http://user.cs.tu-berlin.de/~jgulden/unpaper/archive/20050621JanuszBien/03.pbm and processed it with unpaper -vv --layout single --mask-scan-threshold 0.4 --black-threshold 0.3 --border 0,100,0,0 03.pbm 03up.pbm The resulting file is http://user.cs.tu-berlin.de/~jgulden/unpaper/archive/20050621JanuszBien/03up.pbm Do you get the same result on your system from the same unpaper run? (Btw, the additional '--black-threshold 0.3' is supposed to lead to slightly more saturated black color in the output. A matter of taste, I guess.) Hope that helps, Jens
