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