[sane-devel] sane-brightness range

[Ganapati Hegde]

Hi Allan ,

 

Thanks for the response. Here I would want the device to apply the
brightness and contrast values rather than XSane after image  is
retrived from device.  Is it possible to tell XSane that brightness and
contrast will be applied by the device and XSane should not do it.

 

Regards

Ganapati

there is no requirement in the sane api as to the scale of your
brightness controls. You should be able to leave them at -60 to +60, and
XSANE should scale them to match it's internal requirements. I use -127
to +127 in the fujitsu backend.

Hi  ,

 

I am looking to add new brightness and contrast range from backend code.
If it is possible how can I do this. 

I am using xsane as my frontend and it supports -100 to +100 range. I
need range in -60 to +60. If possible to add new range how it would be
different from xsane range. 

I have tried to add range in backend code but UI will display
brightness and contrast in Standard option window and brightness is not
working. It would be of great help if I got information on this.

 

 

Regards

Ganapati
