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.

with a couple week old cvs, when i run your command i get this:
scanimage -d test -T
scanimage: scanning image of size 157x196 pixels at 8 bits/pixel
scanimage: acquiring gray frame, 8 bits/sample
scanimage: reading one scanline, 157 bytes... PASS
scanimage: reading one byte... PASS
I think this is the interesting part of --help?
Geometry:
-l 0..200mm (in steps of 1) [0]
Top-left x position of scan area.
-t 0..200mm (in steps of 1) [0]
Top-left y position of scan area.
-x 0..200mm (in steps of 1) [80]
Width of scan-area.
-y 0..200mm
or they are used, but the resolution is unused?

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.

'enable-test-options'
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
you would have to inspect the backend to see if there is any code to
deal with that option being in automatic mode. if so, turn it on.

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.

K?re S?rs
Hi,
As a frontend developer, I'm very interested in such addition to test
backend !!

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

Never mind my comments. I missed the fact that you're talking about
1-bit RGB data only (not 1-bit monochrome, which does make a lot of
sense). I think I added 1-bit RGB just because the Mustek scanner
could do it, but it always was a mystery to me why 1-bit RGB data
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
