PDF Thumbnail generation, OCR indexing and extra views integrated with

Project Description


This package provides some nice integrations for PDF heavy web sites.

  • Generates thumbnails from PDF
  • Adds folder view for pdfs so it can use the generated thumbnail
  • Adds OCR for PDF indexing
  • Everything configurable so you can choose to not use thumbnail gen or OCR
  • Ability to create searchable PDFs with HOCR
  • use the @@async-monitor url to monitor asynchronous jobs that have yet to run


OCR requires Ghostscript to be installed and Tesseract. Just you package management to install these packages:

# sudo apt-get install ghostscript tesseract-ocr

This will install tessact 2 not tesseract 3.

Searchable PDFs

Requires svn checkout of tesseract version 3.01 or 3.00 with the hocr configuration in place. Take a look at this thread to find out how to configure hocr

In addition, you’ll need exactimage and pdftk installed

# sudo apt-get install exactimage pdftk libtiff-tools

To not use the latest tesseract version to will have to add this in your instances declaration:

environment-vars += AUTHORIZE_OLD_TESSERACT_VERSION true

Plone 3

  • Requires hashlib


You can convert all at once by calling the url @@queue-up-all.
