If you really plan to write such a program, I would like to offer my help in any way (testing, development, documentation, translation, ...) Bye, Giuseppe
[sane-devel] canonscan 4200F
Hello, I've got a scanner Canonscan 4200F, but since I'm using ubuntu I cannot used it. I'm not a developper, but I'm ready to help to try some codes or to make some tests.

[sane-devel] [announce] tiffscan
Hello, I'm finishing to write a new command line frontend, tiffscan. It aims to be a simple frontend to SANE with batch scan capabilities. Its only output format is TIFF, in both single page and multi page mode. It will correctly fill most TIFF tags and supports lossless compression modes. It will also support RGBI (RGB+infrared) capable backends (none at the moment, but I'm hacking coolscan2) so that you can easily batch scan slides and then use some other postprocessing tool (like VueScan) to refine them. If someone is interested in betatesting, pease drop me a note. -- Best regards, Alessandro Zummo, Tower Technologies - Torino, Italy http://www.towertech.it
[sane-devel] calibration / icm / it8 and colors problems
Did you try this sequence: convert filename.png -profile scanner.icc -profile monitor.icc new filename.png CNZ005.ICC is the wrong profile. CNS12I.ICC is for your scanner. But you need the same brightness, contrast, gamma, ... settings as the windows driver before applying the profile. You'll get better results if you create your own profile in Linux. Thanks for your answers ! With the good profile and with this command line, the scanned picture is better but it is still far from being perfect. I think I will follow your advice and I will buy a IT8.7 scanner calibration targets. I have found some on this website http://www.targets.coloraid.de/ Promise, I will post the result of my calibration:) Philippe m.vr.gr.

You need a viewer that knows how to deal with embedded ICC profiles. If want it to work in all viewers, you need to convert the image to your destination colorspace (you want sRGB): scanimage -i cnz005.icc --resolution 600 image.tiff AND convert -profile sRGB.icc image.tiff after.tiff http://www.color.org/ - Resources - Profiles Daniel
