adjust color and brightness has no effect in Windows Fax and Scan (Canon Lide 110)

[alienshit]

I have testet wiasane in windows7 64 bit Professional.
The installation was quick and simple.
My scanner is connected to a DebianSane Server.
All features of NAPS2 are working fine with my Canon Lide 110 scanner.
Microsoft Fax and Scan works too, but changing of color or brightness has no effect.
Is ist possibile to fix it?
Do other scanner models support this funktions?

Please provide the output of winsane-dbg.exe <saned-hostname>. This way I can identify the relevant options needed to support color and brightness for your scanner.

Hello and have a nice Christmas

I was very happy when I found wiasane today.
But I have a similar problem here with an HP ScanJet G3110.
The color setting and also the resolution can be adjusted. But the brightness and the contrast is not.
In the output of winsane-dbg.exe, it seems to me that the HPG3110 does not support brightness and contrast but only the respective color gamma values. Or am I wrong?
With SaneTwain, the adjustment is made with the color gamma values.

Do I have a chance to integrate the gamma correction into wiasane?

The output of winsane-dbg.exe is here.
