I don't know the answer but I'd like to know what's an area template.
I have been puzzled recently by FineReader 9 when processing image PDFs of old books (coming from Internet archives). I was getting awful results because the "reading" (OCR) process divided the surface of the page to be recognized a little at random, whith some times overlapping zones.
So, I extracted 50 pages out of a image PDF book, let it do its dirty work, and then decided to do it again manually: suppressing all the zones, drawing a text wrapper zone around the page. The result was excellent, of course at the price of lot of work. For these 50 pages, "manual" processing speed was bout two pages a minute...
So, you guess why your "area template" looks tempting to me...
