PDF Solution Pack

Overview

The PDF Solution Pack module adds functionality to Islandora for ingesting and viewing PDF files. It uses the ImageMagick library and module to create derivative thumbnail and preview images. Because of the text-based nature of PDF files, it can also be used to create or append easily searchable text datastreams to the object, which can later be configured through Solr to appear in searches.

Release Notes and Downloads

Configuration

The configuration options for the PDF Solution Pack module can be found at http://path.to.your.site/admin/islandora/solution_pack_config/pdf, and include the following:

Text

Users can either upload a text file of their own, or allow Islandora to extract one from the PDF. Text accompanying the PDF is stored as the FULL_TEXT datastream. If both options are checked under the Text configuration section, and a valid path to pdftotext is entered, preference will be given to a supplied text file on ingest.

• Allow users to upload text file with PDF?: This file must be plain text stored in .txt format.
• Store extracted (or supplied) text?: Checking this box, will display an option to enter a path to the pdftotext executable. This package is not native to most server setups and will need to be installed manually for this option to be functional. Check the pdftotext dependency page for more information.

Thumbnail and Preview

These options set the parameters that will be sent to ImageMagick when ingesting a PDF. ImageMagick will attempt to create these using the first page of the document. Changing these will simply change the size of the derivatives being created.

Viewers

The PDF Solution pack can utilize the PDF.js viewer to display PDF documents inline. To enable, navigate to the PDF Solution Pack's configuration page (admin/islandora/solution_pack_config/pdf) and select the PDF.js as the viewer.
