Re: [sane-devel] Help. Any Ideas?

2017-02-13 Thread Torfinn Ingolfsen
The "Temporary failure in name resolution" messages in your debug
output seems to indicate that the pixma backend also wants / needs a
(DNS) name for your scanner's IP address.
You could try to add it to your local DNS server if you have one, or
to the hosts file on the machine you run SANE on, to see if it helps.

[sane-devel] 16-bit colour in new GIMP

2017-02-13 Thread Vopros
Hello. Can anybody explain what do I need to do with XSane and
xscanimage to be able to scan in 16-bit directly from GIMP? xscanimage
can scan in 16 bit and save the images, unstable GIMP can work with
them, but it only sees the plugin transferring INT32 data. How do I make
them work together?

Gentoo Linux, AMD64, media-gfx/sane-backends-1.0.25-r1,
media-gfx/sane-frontends-1.0.14, media-gfx/gimp-2.9.4-r2.

In general, scanimage isn't very good at detecting network-connected scanners.
However, you scanner might still work.
Things you can try (if you haven't already):
xsane
$ xsane :net:
so something like
$ xsane pixma:net:172.16.184.25

should work.
