command line scanned pdf to text

[Cheryl Homiak]

Thanks. I did try another file and it worked in botyh cuneiform and tesseract so I think the two files I tried were an anomaly or it was a rotation issue. I haven't compared to see which package did the best job but it doesn't hurt to have both of them.

my rock and my Redeemer.

Theresome junk in here you may or may not be interested in. You can pass the script 2 parameters. #1 is the page number.It uses this number to make the output text file name. Page 99 would be named p099.txt. If you don't pass it a page number, it looks for files matching the same pattern and takes the next highest number. So if there already is a p099.txt, it would create a p100.txt. The second parameter is the tesseract psm flag.  The tesseract man page explains these. The default is 3.
