Is always generating a file with 306 bytes

[caitifbrito]

Hello,
I'm testing this program to convert medical books in brazilian portuguese. These books have around 500-700 pages at good quality and, after install all I need to run pypdfocr (one exclusively box for this :), tesseract 3.03 and some of others requirements) when I run it [1] looks like fine, so the product of execution is a file with sufix _ocr.pdf sizing 306 bytes. Its content [2] show nothing good.

  What may be wrong!?

Hi. Can't do anything without a test case. Please upload a pdf so I can try to reproduce.

Did you installed tesseract-data-por (data files for portuguese language) in your distro?

at least in archlinux, tesseract package supports only english language by default. If you need to support other languages, you need to install tesseract-data- package for your distro.

For portuguese language support in archlinux you'll need to run the folowing command:

#pacman -S tesseract-data-por

Sorry for my poor english.
