Hi,<br>
<p>
a new version of the microtek2 backend can be downloaded from<br>
<p>
 <a href="ftp://ftp.muc.de/people/bernds/mtek2/microtek2-pre0.6.291298.tar.gz">ftp://ftp.muc.de/people/bernds/mtek2/microtek2-pre0.6.291298.tar.gz</a> .<br>
<p>
This version should be considered experimental, because it contains a <br>
number of untested features/enhancements. The most important ones are:<br>
<p>
 - Support for non-blocking IO's. Basically this simplifies the whole<br>
   data processing, but the necessary changes affect large parts of the<br>
   respective code. In particular it is interesting to know, whether the<br>
   following options work (they are untested):<br>
<p>
    o color mode on models that print the following line for the data format<br>
      (if 'option dump 1' is set in the microtek2.conf file):<br>
<p>
      Data format:        Chunky data, R, G &amp; B in one pixel<br>
<p>
    o more than 8 bit grayscale and more than 24 bit color scans on models<br>
      that support this.<br>
<p>
 - Preliminary support for a strip and a slide mode. I assume (but am not<br>
   quite sure), that this 35mm slide &amp; filmstrip adapter, which comes <br>
   bundled with some models, requires these modes. <br>
   <br>
   Up to now I didn't figure out, how the backend can<br>
   dynamically determine, whether such an adapter is actually attached to<br>
   the scanner. To enable this feature it is necessary to uncomment the<br>
   lightlid-35 opton in the microtek2.conf file, that is included in the<br>
   archive. Then the frontend should offer a choice of scan sources,<br>
   if the device supports these modes. This is completely untested.<br>
<p>
 - For people, who are annoyed, if the the scanhead moves back and fourth<br>
   during a scan (backtracking): There is a new option 'disable backtracking'.<br>
   At present this option must be activated by uncommenting the respective<br>
   entry in the included microtek2.conf file. This is an advanced option.<br>
<p>
 - The X6EL should no longer produce pixel junk after one successful scan.<br>
<p>
