[sane-devel] Blank threshold adjustable?
Hello, I'm using Ubuntu10.10, sane1.0.14-9 (thanks to Robert Ancell for PPA) and Jeffrey Ratcliffe's great gscan2pdf0.9.31. If I scan in colour, white paper is light grey. It could be nice to see the exact colour of white, but it is not nice for normal use. (And it could make greater a compressed file.) gscan2pdf -- Preferences -- Blank threshold did not make a difference. I need help to adjust the white level. -- Viele Gr??e Werner Holtfreter
[sane-devel] Blank threshold adjustable?
If you are scanning in binary, the sane backend for your scanner would need to expose brightness/contrast/threshold options, and gscan2pdf would need to let you change them. You did not say which scanner or backend. If you are scanning in gray, and something else is binarizing the image, I cannot guess the solution. allan On Tue, Feb 15, 2011 at 9:02 AM, Werner Holtfreter Holtfreter at gmx.de wrote: Hello, I'm using Ubuntu10.10, sane1.0.14-9 (thanks to Robert Ancell for PPA) and Jeffrey Ratcliffe's great gscan2pdf0.9.31.

Hallo m allan, am Dienstag, 2011-02-15 15:21:56 schrieben Sie: If you are leaving the image in gray or color, you would need brightness/contrast/gamma controls from the sane backend, or possibly from gscan2pdf itself. I found brightness/contrast/gamma controls in xsane. After find out the right position from 3 parameters, it works. Back to my preferred gscan2pdf: It can call gimp and it is possible to make the same after scanning with the internal files from gscan2pdf. It gives more control for the user, but I can not see a simple procedure to modify all scans in the job in one step... -- Viele Gr??e Werner Holtfreter

[sane-devel] Scanjet 4400c and 4300c
Le Thursday 20 January 2011 18:41:30 Albert Pool, vous avez ?crit : I said the 4400c was having the wrong buttons configured, but they aren't wrong. I was confused with my 4300c (I'm having both). Sorry for my previous mail. The scanner I mentioned on IRC #sane was also the 4300c. I did not get answer while I was there, so will repeat here. This scanner is said to be supported complete, but doesn't work fully OK. When starting a scan, it is making very strange sounds for a minute or two before starting to scan, and the scanning itself is very slow.

[sane-devel] LIDE 60. configure scanner - Mac Terminal
wow- you're pretty far down the curve on this one. I'll try to be more explicit. We are talking about source code. Not conf files (yet). Not compiled libraries (yet). You don't currently have any source code on your box unless you have explicitly downloaded it. We are going to download, modify, and compile that source code into a library. I've never done any of this on a Mac, so every detail here is suspect. The general idea is the same. 1. install the libusb-dev package (or libusb-devel, not sure what your OS calls it) 2. install gcc package and it's required dependencies 3. install the utility 'make' (it might be called gmake on your platform) 4. download latest sane-backends from http://www.sane-project.org/snapshots/ It will be named something like: sane-backends-git20110215.tar.gz --use the terminal from here on out 5. extract the file you just downloaded with this command (correct filename if different): tar xzf sane-backends-git20110215.tar.gz This will create a new directory, named something like: sane-backends-git20110215 6. Change in this new directory: cd sane-backends-git20110215 7. edit backend/genesys_devices.c file. I like vim, you can use whatever editor you want, including some icky gui thing, as long as it does not try to reformat the text. 8. around line 1573 you will see a section of data for the lide 60. Near the end of that section, there are a bunch of flags, separated by the '|' symbol. Remove the lines with 'CALIBRATION' in them, and add one in their place that says: '| GENESYS_FLAG_NO_CALIBRATION' 9. save the file. 10. Run the following command (all on one line) BACKENDS=genesys ./configure --prefix=/usr --sysconfdir=/etc --disable-locking 11. Run the following command (takes awhile) make 12. copy the file backend/.libs/libsane-genesys.so.1.0.23 over top of the copy provided by your distro, not sure where it is on a Mac. Probably in /usr/local/lib? Note that the file name will change- your current file might end in .21 or .22, that's fine. We want the new one to have the same name. We are replacing the old file. You can save the old one before you overwrite it if you want. 13. test with scanimage or xsane and various options. Only step #12 needs to be done as root. allan -- The truth is an offense, but not a sin
