I know about the test backend, and it is very useful.
However, it cannot cover every combination of option type/reload that is
out in the wild.
I often have to spend hours mocking up a backend from a log file to be
able to reproduce a bug in gscan2pdf, in order then to be able to fix it.

OK, my fault again... I failed to notice that when I converted sanei
directory to automake a few days back that it stopped finding config
files. :-(
It will be fixed within the day. Need to add reference to $(

Hi all,
I was converting the testsuite directory to automake but I noticed in
CVS version of sane that the following basic command doesn't work. So
not much for me to test right now.

Absolutely right. Thanks for the info.

In the test backend, the only option with cap & SANE_CAP_AUTOMATIC
also has cap & SANE_CAP_INACTIVE.
This means that it is impossible to test sane_set_auto. Is this a bug,
or am I missing something?
Regards
Jeff
actually, if you look at the code, that option is enabled if you set
'enable-test-options'

Hi,
As a frontend developer, I'm very interested in such addition to test
backend !!

Hi!
While developing a frontend I wanted to handle gamma tables, but I did not
have constant access to a scanner providing gamma tables, so I added gamma
tables to the test backend. I hope somebody can have use of it. I'm attaching
my patch against sane-backends-1.0.18.

Hi,
I've changed the test-backend, that way, that the reader-process now
terminates, when running as thread.
This change should allow to run the test-backend on MacOSX without
patching the sanei_thread lib.
Mattias, you might can check this. By removing your patch from the
MacOSX SANE-version, th

I think that makes sense.
When a backend really does support this then it
can send it as 8 bit rgb image.

Hi all,
while playing with the test backend, I noticed that the "scan data"
produced for the grid pattern in 1 bit RGB mode differs from the output
for 1 bit grayscale mode. The data for gray scale mode is like:
... 00 00 00 0f ff ff ff f0 00 00 00 ...
while the data for 1 bit RGB mode

I'm not sure, either. I just tried everything the standard allows...

Hi,
Version 1.0.11 of the test backend can be dowloaded from
http://www.meier-geinitz.de/sane/test-backend/ .
Changes:
- Bugfixes
- different return stati for sane_read()
- man page
- it's beta now
I would like to include the test backend into sane-backends so I'm
interested in any bug reports
