Any Accurate O C R Programs in DOS I can run in Linux?

[John G. Heim]

Well, I was goiing to say that too -- that the problem with tesseract 
probably wasn't the quality of the OCR itself but the orientation and 
cropping. But that's small consolation to someone who is used to having 
their software deal with all that on it's own.  There probably is 
something out there in open-source land that does the rotation, at 
least. If 20% of the words in the text aren't in the dictionary, rotate 
the image and try again.  Something like that would be easy enough to 
write. But if there is something like that available as open source, I 
am unaware of it.
