collective.documentviewer integrates documentcloud's viewer and PDF processing into Plone.

Example viewer:

Works with

Besides displaying PDFs, it will also display:

- Word
- Excel
- Powerpoint

Async Integration

It it highly recommended to install and configure in combination with this package. Doing so will manage all pdf conversions processes asynchronously so the user isn't delayed so much when saving files.


The product can be configured via a control panel item Document Viewer  Settings.

Some interesting configuration options:

Storage Type
 If you want to be able to serve you files via amazon cloud, this will allow you to store the data in flat files that can be synced to another server.
Storage Location
 Where are the server to store the files.
 Use tesseract to scan the document for text. This process ca be slow so if your pdfs do not need to be OCR'd, you may disable.
Auto Select Layout
 For pdf files added to the site, automatically select the document viewer display.
Auto Convert
 When pdf files are added and modified, automatically convert.

File storage integration

If you choose to use basic file storage instead of zodb blob storage, there are a few things you'll want to keep in mind.

1. Use nginx to then serve the file system files. This might require you install a local nginx just for serving file storage on the plone server. You can get creative with how your file storage is used though.
2. Since in plone's operation, it can be interrupted and the deletion of a file on the OS system system can not be done within a transaction, no files are ever deleted. However, there is an action you can put in a cron task to clean up your file storage directory. Just call the url http://zeoinstace/plone/@@dvcleanup-filestorage.

Upgrading from page turner

If you currently have page turner installed, this project will supercede it. Your page turner views will work but no future files added to the site will be converted to page turner.

To convert existing view, on every page turner enabled file, there will be a button Document Viewer Convert that you can click to manually convert page turner to document viewer.

To convert all existing views, go to portal_setup in the zmi, upgrades, select collective.documentviewer, click to show old upgrades and there should be an upgrade-all step to run.

Upgrading from pdfpal

If you want to upgrade from pdfpal, it is recommended that you simply uninstall pdf pal.

Document viewer will disable parts of pdfpal if installed with it otherwise. If you still want both installed, you'll need to upgrade to at least version 0.7b5 in order for it to play nice with document viewer.

Also, version 0.7b5 has the best uninstall support so if you're going to uninstall the product, first upgrade your egg to 0.7b5.
