[Bug-ocrad] OCR of messy computer printout

[Karl Berry]

Hi Antonio and anyone else,

I tried ocrad 0.21 on the attached image, which is a not-very-cleanly
scanned printout of a Fortran program.  I first ran ocrad <x.pnm.  The
result starts like this:

____I__ _


| __ __ F rN c_ _= E l___hN. _ OR_=__X.UL | dl '_ | |_lolc R_ FL | _:_ I wol _ 
[ _ol [g_c_ __o..oB..

The actual text starts like this:
   uen4059

100*#FTN GPP=(NWARN,...etc...


I tried playing with the --thresheld, but the results will not
noticeably better.  Are there other options or approaches which might help?

Thanks,
Karl
