[sane-devel] Epson perfection 4870 - gamma and brightness in 16bit mode

2005-01-17 Thread Richard Beare
Hello, I have an Epson perfection 4870 photo (aka GT-X700). I'm trying to use it in what is possibly an unusual way. I seem to be able to get most of what I want using xsane, but not using scanimage. I need to use something commandline oriented in the end in order to automate some of the steps

[sane-devel] Epson perfection 4870 - gamma and brightness in 16bit mode

Richard, the Perfection 4870 does not have an exposure setting, and only supports 8bit Gamma tables. I suspect that you see the combined gamma applied by the scanner and xsane, whereas scanimage only gives you access to the scanners gamma setting. Have you tried xscanimage? Karl Heinz On Jan
