Hello,<br>
<p>
please help me, I do not find a solution for the following problem<br>
concerning the microtek backend. The followiong command was issued:<br>
<p>
scanimage -l 0 -t 0 -x 210 -y 297 --resolution 120 --brightness 0<br>
--contrast 45 --exposure 1 --black-level 20 --midtone 128 --white-level 255<br>
--gamma-mode Scalar --analog-gamma-r 2.6 --analog-gamma-g 2.8 --analog-gamma-b 2<br>
<p>
scanimage aborts with the following message:<br>
<p>
scanimage: attempted to set inactive option analog-gamma-r<br>
<p>
I did not find a way to specify the analog gamma values. Regardless of<br>
the --gamma-mode option, the message is always the same.<br>
<p>
The scanner is a Microtek ScanMaker E6, previously driven by the mtekscan<br>
driver where the analog gamma values could be specified without any<br>
problems and worked as expected.<br>
<p>
The OS is Linux 2.0.36 (SuSE distribution with SANE pre-installed).<br>
I just downloaded the latest SANE version, but the problem still remains.<br>
<p>
Thank you for your help.<br>
<p>
Regards,<br>
Roland Genske<br>
