This package does not work for me... #7

Somehow, it does not seem to work with my directory layout (Ubuntu 10.04). This seems to be a tesseract-related issue (Cuneiform seems to work)...

Hi, and thanks for sharing your code !

I have the same issue as @sch82812121, with log such as: 

Converting 4 pages
==========
Extracting page 1
Converting page 1 to ppm
Running OCR on page 1
Tesseract Open Source OCR Engine v3.03 with Leptonica
mv: cannot stat ‘1.hocr.html’: No such file or directory
Error while running OCR on page 1
==========

and so on for each of 4 pages. Maybe you have an idea where this could come from? Best, Mahé

Hi!

Tesseract in Version 3.03 does not use the .html extention for the hOCR files anymore, it uses .hocr instead. To fix it you can edit the sourcecode in pdfocr.rb, lines 336 to look like this:

sh "tesseract", "-l", language, basefn+'.ppm', basefn, "hocr" and remove or comment out the next line

sh "mv", basefn+'.hocr.hocr', basefn+'.hocr'

However, an even better solution is found here: https://github.com/snowboard975/pdfocr/commit/4d274c918346cb56a7a766cef566e6fb4b11171e so long hank

Wish this issue was titled something more relevant... This is an important fix
