  • Look for a directory called tess/tessdata on your machine
    • In PDF Studio 9 and above, it is located under your user folder under the “.pdfstudioX” folder (where X is the version number)
    • In PDF Studio 8, it is located under the installation directory, for instance C:\ProgramData\PDFStudio8 for Windows 7, Windows Vista, Windows 8, Windows 10.
  • Extract / Copy the files contained in the gz file into the tessdata directory:
    • For Icelandic: isl.traineddata
  • Open the file called languages.xml located under the same directory in a text editor and add the corresponding entry for your new language file:
    • For Icelandic:
      <language name="isl" desc="Icelandic" file="tesseract-ocr-3.02.isl.tar.gz" />
    • Don’t worry about any other tags present in other languages (such as URLPrimary), they are not needed.
  • Exit and restart PDF Studio.
