Islandora 7.x-1.0 (Beta)
This documentation covers the latest release of Islandora 7.x.
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.
ImageMagick is required to create derivatives. ( Debian/Ubuntu
sudo apt-get install imagemagick )
pdftotext is required to automatically create a FULL_TEXT data stream. ( Debian/Ubuntu
sudo apt-get install pdftotext
sudo apt-get install gs)
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:
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.
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 change the size, but not the aspect ratio, of the derivatives being created.
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.
The PDF Solution Pack comes with the following objects in http://path.to.your.site/admin/islandora/solution_pack_config/solution_packs:
An object created using the PDF Solution Pack's content model will have the following datastreams:
Default Fedora relationship metadata
MODS metadata record created during ingest
Dublin Core record
|OBJ||Original PDF file uploaded|
Thumbnail image created by ImageMagick during ingest
|PREVIEW||Preview image created by ImageMagick during ingest|
|FULL_TEXT||Optional datastream either uploaded during ingest, or created by the pdftotext executable|
|PDFA||Optional archival datastream created by the ghostscript executable|
The PDF Solution Pack comes with the PDF MODS Form.
