Hi,<br>

<p>
A backend with support for an ADF (and TMA) is now available on<br>
<p>
<a href="ftp://ftp.muc.de/people/bernds/mtek2/microtek2-pre0.5.080998.tar.gz">ftp://ftp.muc.de/people/bernds/mtek2/microtek2-pre0.5.080998.tar.gz</a> .<br>
<p>
The .gz file contains a .c and a .h file, that can simply be copied over<br>
the old files. Then rebuild and reinstall sane.<br>
<p>
Since I have neither a TMA nor an ADF, parts of the code are untested.<br>
What should happen is, that a new option "scan source" is enabled, when<br>
a TMA or ADF are detected.<br>
<p>
If the user switches from flatbed mode to TMA or ADF mode a new set of<br>
option settings becomes available, because the scanner attributes for each<br>
of the three scan sources are slightly different, for example the scan areas<br>
have different sizes ( in case of my Scanmaker 630 flatbed is 8.5'' x 11.7'',<br>
TMA is 5.5'' x 6.0'' and the ADF supports 8.5'' x 13.5'' ).<br>
<p>
If the TMA source is selected the lamps should be toggled, too.<br>
<p>
I have tested this by faking the presence of a TMA and ADF. However, if<br>
I select a mode other than flatbed and start a scan the scanner silently<br>
switches to flatbed mode and starts scanning from there. ( I would rather<br>
have expected an error message ).<br>
<p>
In case of the TMA it selects the smaller scan area and in case of the<br>
ADF it selects the bigger scan area and tries to scan beyond the bottom<br>
of the available area of the flatbed.<br>
<p>
But the bits in the "set window" command, that select the medium are<br>
correctly set, so I hope it works, if a TMA or ADF are really connected.<br>
