command line scanned pdf to text

[John G Heim]

I've been scanning in the D&D 5th Edition player's handbook. I tried 
every open source OCR program I could find and tesseract was easily the 
best. On pages that are just prose, it probably does about 99% accuracy. 
Even on pages where that are 2 columns of prose, it does really well if 
you tell it to look for that. Somebody sent me a pdf of the same book 
done with a professional OCR program for Windows. The results are 
approximately equal. Tesseract may lack the bells & whistles of 
commercial products but for accuracy, it's pretty good.
