Hello!  I am a new subscriber to this mailing list, and from the looks of<br>
the archives, it seems to be very effective.  <br>
<p>
I finally replaced the ISA PnP SCSI card which came with my HP <br>
Photosmart R032 with a more Linux-friendly BusLogic card, and have since <br>
been trying out SANE-pre1.01-3.  I am able to scan slides just fine, <br>
with only a few odd behaviors:  <br>
<p>
- The software seems to run the slide in completely, and then scan it on <br>
  the way back out, even for previews.  At higher dpi settings, it runs <br>
  slowly in both directions, even though it's only acquiring on the way <br>
  back out.  <br>
<p>
- The vertical (y) postion of the slide seems to slip by about 1mm each <br>
  time the slide is fed in and out.  In other words, if I draw a crop box in <br>
  the preview window, I get a same-size box in the output, but it is of <br>
  a rectangle shifted downward in y 1mm or so.  Subsequent feeds shift it <br>
  more each time, as if the backend or the scanner are loosing track of <br>
  where the slide is physically.  <br>
<p>
I am very interested in getting 10-bit support working with this scanner, <br>
and also possibly downloadable tone maps.  I can imagine putting together <br>
calibration curves for various film brands (Kodak Gold 100, Fuji Reala, etc.) <br>
which are either downloaded as tone maps or are applied to the 10-bit data<br>
in software.  I would be willing to help out with implementing and/or testing <br>
this kind of stuff.  I have some experience in coding graphics routines, <br>
and I spent some time reading the HP SCL docs over the weekend.  Are there <br>
any docs from HP specific to the Photosmart?  <br>
<p>
Thanks to everyone who has contributed to SANE!<br>
<p>
John Pitney<br>
