[sane-devel] 3 minor problems with current (20061202) CVS code on OS/2
Hi, two minor problems on OS/2 with current CVS (since 1. 12. 2006) 1. configure (generated by Autoconf 2.59e) fails and claims not to find grep (which is bogus) Running autoconf (2.59) locally solves the problem. 2 I have to add #include sys/socket.h to .sanei\sanei_tcp.c because otherwise AF_INET is not defined. 3. : *** No rule to make target `libsane-epson2.la', needed by `all'. Stop. probably a temporary problem until epson2 - code is added.. Thanks for listening Franz

I have also fallen for this and been the Bad Man to break the OS/2 build by simply using the default autoconf installed on my debian box! The solution is just to install autoconf 2.59 (eg: from tarball), use that to generate ./configure, test and check in the result. There used to be a note about correct autoconf versions on the SANE website although a quick search just now failed to find it. cheers, Jon == Jon Chambers = http://www.jon.demon.co.uk, 020 8575 7097, 07931 961669 =

[sane-devel] trying to get a Benq4300U USB scanner working .....
Dear sane people, I have tried to get my scanner to work a number of times under Fedora Core 6 on my machine (1200 MHz Athlon) but have not succeeded. I am now trying with Debian on the same machine on a second drive. It is pretty recalcitrant and it may still not work but I will post some of my efforts here and if you would make suggestions I would be grateful. What is REALLY sad is that if I can't succeed I will have to wipe Fedora off and reinstall Windows 98 just so I can scan images. Yikes The other alternative is to go to the library and use the scanner there. I would still be using Windows but at least not on my own machine. OK. Here goes. As you can see I have edited the snapscan.conf file that lives in /etc/sane.d and bunged in the driver for the scanner I use and the device directory /dev/usb/scanner0. more snapscan.conf #-- General #--- # Change to the fully qualified filename of your firmware file, if # firmware upload is needed by the scanner firmware /home/mikef/benq4300/u222v067.bin # If not automatically found you may manuaully specify a device name. # For USB scanners also specify bus=usb, e.g. # /dev/usb/scanner0 bus=usb # For SCSI scanners specify the generic device, e.g. /dev/sg0 on Linux. # /dev/sg0 #--- # No changes should be necessary below this line #--- #-- SCSI scanners -- # These SCSI devices will be probed automatically scsi AGFA * Scanner scsi COLOR * Scanner scsi Color * Scanner scsi ACERPERI * Scanner #--- USB scanners --- # These USB devices will be probed automatically # (This will currently work only on Linux) # Benq/Acer/Vuego 310U usb 0x04a5 0x1a20 usb 0x04a5 0x1a26 # Benq/Acer/Vuego 320U usb 0x04a5 0x2022 # Benq/Acer/Vuego 620U / 620UT usb 0x04a5 0x1a2a usb 0x04a5 0x2040 # Benq/Acer/Vuego 640U usb 0x04a5 0x2060 # Benq/Acer/Vuego 640BU usb 0x04a5 0x207e # Benq/Acer/Vuego 640BT usb 0x04a5 0x20be # Benq/Acer/Vuego 1240U usb 0x04a5 0x20c0 # Benq/Acer/Vuego 3300 / 4300 usb 0x04a5 0x20b0 # Benq/Acer/Vuego 4300 usb 0x04a5 0x20de # Benq/Acer/Vuego 5000 usb 0x04a5 0x20fc # Benq/Acer/Vuego 5300 usb 0x04a5 0x20fe # Agfa 1236U usb 0x06bd 0x0002 # Agfa 1212U usb 0x06bd 0x0001 usb 0x06bd 0x2061 # Agfa Snapscan e10 usb 0x06bd 0x2093 # Agfa Snapscan e20 usb 0x06bd 0x2091 # Agfa Snapscan e25 usb 0x06bd 0x2095 # Agfa Snapscan e26 usb 0x06bd 0x2097 # Agfa Snapscan e40 usb 0x06bd 0x208d # Agfa Snapscan e42 usb 0x06bd 0x20ff # Agfa Snapscan e50 usb 0x06bd 0x208f # Agfa Snapscan e52 usb 0x06bd 0x20fd # Epson Perfection 660 usb 0x04b8 0x0114 # Epson Perfection 1670 usb 0x04b8 0x011f # Epson Perfection 2480 usb 0x04b8 0x0121 mikef@spc2-burn3-0-0-cust329:/etc/sane.d$ OK, now let's try to detect it.

Try scanimage -L and read the backend's manpage. # Not checking for parallel port scanners. # Most Scanners connected to the parallel port or other proprietary ports # can't be detected by this program. It looks like it has found it. But don't get too excited. Let's try something else; scanimage -L No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages). Hmmm.. It can't find it now. I think if it is a USB device I once read somewhere that scanimage -L might not work so easily c.f. SCSI in this situation. Comments please.

[sane-devel] Does Epson Expression 10000XL support auto cropping
That depends on the scanner. Some scanners do allow image processing in the scanner, others just deliver the raw image data. On 12/1/06, Sam sas...@yahoo.com wrote: I have a general question as to the inner workings of a scanner. Do scanners (or Epson) generally capture a Raw image and pass it on to a front end program? or does the scanner do some image processing. I guess if a scanner can do some image processing, then the same or better can be done at the front-end side. Does anyone have a favorite front-end to hook up to SANE? thanks sam --- Karl Heinz Kremer k...@khk.net wrote: The scanner does not support auto cropping. This feature would have to be implemented in a frontend.

[sane-devel] Missing greys
Hi Henrik Henrik Uggla schrieb: I've got a Canoscan Lide 50. I have discovered that when I scan at 150 dpi or more the greys are missing in depth (in the black end). But when I scan at only 75 dpi the result looks much better since darker and lighter pixels are mixed to show the right grey nuance. Is it possible to have this behaviour at higher resolutions as well and in that way creating those missing greys? I can't explain why there is a difference between calibration for 75dpi compared to 150dpi(You didn't scan them at different bit depth, i guess). But anyways, dark shades were incorrect since the beginning of Canon LiDE 50 support. I had some improvements to the calibration process sitting in my local copy since about 3 months, so i just committed them. You can get them from the cvs repository. Test results for the current method are welcome. Regards, Pierre
