Q: How can I manually install the OCR languages in PDF Studio.

A: First, it’s recommended that you download the OCR packages directly through PDF Studio as this will be the most up to date and prevent any possible issues. See OCR language download troubleshooting

If the above still does not work you can try to manually install OCR languages into PDF Studio by doing the following:

  1. Find the language you wish to install from the list below
  2. Click on the link to download the language pack files
  3. Extract / Copy the files contained in the gz file into the following directory:
    • {User Home Folder}/.pdfstudio[version]/tess/tessdata
      where [version] is the version of PDF Studio you are running, for instance .pdfstudio2020
    • Read more about your user home folder and pdfstudio folder
    • NOTE: the pdfstudio folder starts with a dot and is a hidden folder, you will need to un-hide it
    • NOTE: you may need to create both the “tess” & “tessdata” directories
    • Download Trained Data File from our website https://download.qoppa.com/ocr/tess302/osd.traineddata.tar.gz, extract and copy the file into “tessdata”folder
  4. Restart PDF Studio
  5. You will now be able to select the new language from the drop down in the OCR wizard
