Re: [sane-devel] OS X 10.9.5
There is a link on Ellert's page “Older versions” Here it is below.

[sane-devel] OS X 10.9.5
Hi everyone! My grandpa gave me the mission to get his very old SnapScan Touch AGFA usable again. So I read about the Twain Sane on different forums and I concluded that it would work. So I checked how to use it and when I downloaded the TWAIN SANE Interface and tried to open the libusb.pkg, it told me (sorry, my computer is in French) a message like : WRONG VERSION OF Mac OS X This package was compiled for version 10.11 My computer is a Mac OS X 10.9.5. So I checked on the historic topics to see a problem like mine, I tried different pages to see if I was able to download an old version and I must have missed a thing. Where can I find a version of the Twain Sane Project for my Mac OS X 10.9.5 iMac.

You apply it on the incoming (or gamma corrected?) RGB values via matrix multiplication like so R' = 1.4234 * R + -0.3230 * G + 0.0061 * B + -29.7088 G' = 0.0600 * R + 0.9677 * G + 0.0719 * B + -31.3147 B' = 0.1562 * R + -0.5104 * G + 1.4530 * B + -28.9059 R, G, B are the values before correction, R', G' and B' the ones after. You may have to clamp the results into the [0,255] range (assuming 8bit samples).

Hi Klaus, Julian, and Dave and thank you very much for your suggestions. As I mentioned in a previous mail, there was a file on the CD called "Generic Positive.ft". The file format is neither understood by sane nor by me. The good thing is that it's pure ASCII. I first extracted the lookup table FilmLut 0.000.000.00 7.507.506.00 [...lines omitted...] 4094.11 4094.09 4094.43 4095.00 4095.00 4095.00; and plotted the curves. See http://ms25.ddns.net/plot-lut.pdf The first page contains a linear plot, the second page shows the same plot scaled logarithmically. Please note that when scaled logarithmically, the Gamma value is just the slope (dy/dx) of the curve. As you can see, two different Gamma values are used. I then loaded a scanned image into Gimp and adapted the curves according to the linear plot. The results were amazing. I did not expect to get such good results almost immediately. But the result isn't perfect. It turned out that the lower left part of the curve is extremely critical. Small changes make huge differences and there is no way to get things correct if the only tool you can use is a mouse. The next step is to write a script which applies the lookup table to pnm files. The pnm file format is quite simple and I think that I can write such a script within a reasonable amount of time. I could probably improve the results if anybody tells me what these values mean and how to apply them: FilmMatR1.4234 -0.32300.0061 -29.7088; FilmMatG0.06000.96770.0719 -31.3147; FilmMatB0.1562 -0.51041.4530 -28.9059; I suppose that I can scan all my slides automatically now and can apply the color profile of my scanner afterwards. Everything I can do without manual interaction is fine for me (I've abt. 7200 slides) and GUI tools are not very helpful at this stage. I'm sure that GUI tools like GIMP are helpful in order to enhance individual images.

Please check out https://github.com/kkaempf/sane-backends.git. The 'kkaempf' branch is one commit on top of current sane-backends#master. This version gets rid of the 'flags' column in pieusb.conf and evaluates the inquiry data instead. Compile with 'make', install with 'sudo make install' and then run xsane. Good luck !
