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.

• Allow users to upload text file with PDF?: This file must be plain text stored in .txt format.
• Extract text streams from PDFs using pdftotext?: 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 (Copy) dependency page for more information.
• Create PDF/A archival derivative from PDF: Create a PDF/A version of any uploaded PDF. PDF/A is a restrictive standard that prohibits more easily broken components of the PDF spec, such as fillable forms and DRM. The PDF/A derivative will not be used for display. Requires ghostscript to be installed on the server.
