I see those options , however they seem to work only with command line
from what I can see.

If you use them with scanimage, then that would be from the command
line. They are available from other frontends that support them, e.g.
gscan2pdf.


They should be available with any self-respecting SANE frontend.  These
options are not marked as advanced.


I am looking for the delay option to be the default behavior whenever
the test backend is called. That is what I am hoping for.

On my Debian system, I can edit /etc/sane.d/test.conf and change the
defaults.


This is also documented in the manual page for the test backend.

Hope this helps,

saners

in particular genesys_gl847

a query or two about <backend>.conf file

 1) do all, most, some backends support such runtime argument
    alterations?

 2) i see scanimage is checking for and reading ./genesys.conf
    and /opt/csw/etc/sane.d/genesys.conf

 3) i've tried to enter options in ./genesys.conf, but have
    not been able to get them to a) work or b) cause an
    error or warning.  is there anyplace in the sane documentation
    world that defines/describes the format for these arguments
    placed in a <backend.conf> file?

    i seem to think i've seen something like that but i'm not
    able to re-find it!  rtfm'ed sane.7, scanimage, sane-genesys
    sane-test and grep'ed around looking for '\.conf'

    ah-ha! sane-u12 -- but those lines don't work either

    tried lots of variations including
          option='flag:arg'
          option flag arg
          option -flag=arg
          option="-flag arg"


if anyone provides guidance even if pointer(s) to relevant code
i will take/make time to write-up a manpageish file and submit
for incorporation ...

thanks

aloha
