Make available buttons and sliders depending on scanner

[apfeiffe]

Sam,

may I ask you to make the available buttons and sliders dependend on the output of scanimage -A?
For example:

[scanservjs@scanprint ~]$ /usr/bin/scanimage -A

All options specific to device epson2:libusb:001:006:
Scan Mode:
--mode Lineart|Gray|Color [Lineart]
Selects the scan mode (e.g., lineart, monochrome, or color).

[...]

--brightness 0..0 [inactive]
Selects the brightness.
--sharpness -2..2 [inactive]

Otherwise the command will fail with something like:

scanimage: attempted to set inactive option brightness

Thanks,
Andy

Hey Andy,

That's a good idea! I will look into it and make it happen

I've added a new feature with device detection using scanimage -A as per your suggestion. Scanservjs now checks to see if a feature is allowed before using it. Currently implemented for brightness, contrast and depth. What is not yet implemented is anything in the user interface to stop users wasting their time with it.
