I'm new to this list, and picked up the above from the archive on the
Web - it was in answer to a post by Nicolas Deslisle.
This is just to confirm that changing the relevant three lines in the
code to these:
static const int x_table_size = 0x13DC;
static const int y_table_size = 0x17BA;
static const int calibration_table_size = 0x3BC4;
... (just doubling each number) makes my Primax Colorado D600 work on my
system (Kernel 2.0.36-0.7, libtiff 3.4-4, parallel port set to SPP)
I have to give the command-line dimensions as twice what they really are
(-d6x6 if I want -d3x3 inches - which makes sense given the above
changes, although I haven't yet looked for where in the source one could
fix that).
The scan has a green cast (a known bug I gather) which is trivial to get
rid of using the gimp's Auto Levels). Otherwise, the scan looks pretty
good.

I'll see if I can get these for you - don't yet know where to look.
One detail : it doesn't work if I pass the cable through my HP7200 CD
writer - only with the cable going direct to the scanner - no big sweat.
Thanks for all the good work on this!
Cheers,
Colin
