Hello,

i'm getting the same error

Look at the tmp folder: lrwxrwxrwx 1 root root 17 Mär 28 12:02 0001.cleaned.ppm -> 0001.deskewed.ppm lrwxrwxrwx 1 root root 8 Mär 28 12:02 0001.deskewed.ppm -> 0001.ppm -rw-r--r-- 1 root root 63492 Mär 28 12:03 0001.hocr.hocr -rw-r--r-- 1 root root 367153 Mär 28 12:02 0001.orig-img-000.jpg -rw-r--r-- 1 root root 33 Mär 28 12:02 0001.orig-img-info.txt -rw-r--r-- 1 root root 10996739 Mär 28 12:02 0001.ppm -rw-r--r-- 1 root root 26 Mär 28 12:02 pages-info.txt -rw-r--r-- 1 root root 17 Mär 28 12:02 tmp.txt

File "0001.hocr.hocr" could be the problem

Maybe this helps.

hierchristian commented 10 years ago

Hi,

in ocrPage.sh change mv"$curHocr.html" "$curHocr" to mv "$curHocr.hocr" "$curHocr". Sry, dont know the line.

Now it works at least for me.

Bye

Hey,

I'm Having the same issue as gitmaster2013 after upgrading from Kubuntu 13.10 to 14.04 However, the tip from miamoebel doesn't work for me. After changing to $curHocr.hocr" "$curHocr" I get the following:

Hi,

The library python-reportlab 3.0-1 doesn't work, you should force the 2.7-1 (package in testing).

Sincerely,

Daniel Berthereau Infodoc & Knowledge management

MzunguKichaa commented 10 years ago

Thanks Daniel,

that worked for me (but I'm using reportlab 2.6-1, didn't get the 2.7-1) in conclusion with the fix from miamoebel. If I don't change the mv... line as miamoebel suggested, I'm still getting errors. If you want, I can post these errors.

Thank you very much!

Malte

achrist42 commented 10 years ago

Hi,

I can reproduce this issue using Ubuntu 14.04. The problem stems from new versions of tesseract and reportlab.

On my system the following two steps are necessary to make OCRmyPDF work:

  1. As @miamoebel already mentioned in the file ocrPage.sh on line 190 change mv "$curHocr.html" "$curHocr" to mv "$curHocr.hocr" "$curHocr".
  2. In recent versions of reportlab _AsciiBase85Encode changed to asciiBase85Encode. This pull request by @dreuter shows how to fix this issue by editing hocrTransform.py: https://github.com/fritz-hh/OCRmyPDF/pull/71/files
AvanOsch commented 10 years ago

Thanks @andreas-christ! That solved my problem, without (re-)installing/downgrading anything. Line 190 of ocrPage.sh, and just 2 changes to make in hocrTransform.py: Line 50 and 92
