Hello, I'm beginning understanding the backend code for my Umax scanner.
Now I've included 2 screenshots, one is the find_zero.pgm, which is where is detect the black stripe and the other is the calibration strip, both under the scanner's lid. The find_zero.pgm seems fine, but not the calibration.pgm. My question is, what should the calibration.pgm image should look like? Should it be a plain grey image all the way long? Thank you.

It applies on top of the backends/coolscan2.c file of sane-1.0.16 I also uploaded a precompiled library to http://cvs.fzk.de/~ariel/linux/libsane-coolscan2.so.1.0.16 it is only one file which you could use to replace the one in /usr/lib/sane/libsane-coolscan2.so.1.0.16 No warranties that this will work, but you can try if you want to avoid patching and compiling sane. This patch worked for me and should in principle enable for the LS50/5000 exactly the same functionality that the older LS40/4000 scanners have in Sane. I tested it only with "scanimage", because kooka and xscanimage were not behaving correctly (although that has nothing to do with LS50 support), and getting the right exposure with scanimage seems to be tricky. Also, it seemed to me that the scans i made were not correctly in focus, but that could be some other issue. Testers welcome! :-) Cheers, Ariel -------------- next part -------------- A non-text attachment was scrubbed...

I'll write one up. Can someone direct me to a skeleton program from which to build from? ie, what functions do I need to support with what interface etc? Lando
