Not quite. I was hoping that the scanner would alre
Hi,
Thanks for your comments.
I don't think that there is an image - the log file for the ltrace
output is only ~40kb. I think that the scanner is returning the array
and there is no post-processing by the diagnostic application.
The scanner is also capable of returning an image of the scanned f
Hi,
I think it's a bit simpler than that. The diagnostic software shows an
"array" showing the marked boxes. Here's what I get form the
diagnostic software when I scan a slip:

unless your log does
but is this diag software output post-processed by the pc? if you have
logs of the data in flight, and there is no image, then you dont need
sane, you need a standalone app.

i have quite a bit of omr experience, and have done a bit with rs232
in the past, but never scanners. do your logs show the actual data
being passed? if so, i think your first effort should be to extract
