Hi Raffaele,

I am using ocrad 0.25 and I found that it doesn't recognize underlined
characters / digits. Do you have any suggestion on how to get it to work ?
If the underline touches the characters, then ocrad can't recognize
them. Sorry.
Also, how do I write a filter that only generates letters or number ? I can
use upper_num, but then it doesn't outputs lowercase letters.
This is easy. Just write a filter file[1] consisting just of the
following line:
[0-9A-Za-z]
You may add other lines with a conversion for each character you want
recognized:
'(' = 'C'
And that is all.
