If you have version 2.0 then pages 20-21 will tell you what you need
to know.  Don't have version 2.0???  GET IT!!!  YOU'LL WANT IT!!!
I think upgrading used to cost $10 - call NewTek to be sure.

With it you can make the three primary color scans and save EACH
at 7-bits per pixel per color.  Yes, Digi-View internally stores
the digitized image at 7-bits per color in RGB mode and converts
this to the given display mode depth (number of colors).

Now, once you've saved off your 21-bit image you can upload it to
your favorite color workstation, filter it with a simple [pick your
language] program to get the right # of bit planes, and display it.
A friend and I used to do this at SMU with my Digi-View and the
university's graphics equipment.

If you have Version 2.0 then the file formats are described in the
back of the manual.

If you can't write one from the manual let me know and I'll see about
getting a copy of what we used at SMU.

Chuck McManis(sp?) at Sun wrote an article for BYTE a while backa
about simple image processing on the Amiga.   Check it out!!

T'would be a bit more difficult than that.   You've got timing and
other cruft to figure out as well.  You need to be able to READ from
a parallel port.... that is usually used for WRITING.  It would help
if the circuit in that little white sealed box was available....

I digress.... Time to get out in to that blizzard going on out there!!!
