- ghostscript (version 9.0 preferred).



- Poppler



- tesseract (optional)



- qpdf



- OpenOffice or LibreOffice (optional, for doc, excel, ppt, etc. types)

Installation on Cent OS/Red hat

-------------------------------



Special instructions for CentOS have been contributed by Eric Tyrer.

You can access them via `the git hub repo file location `_.



Installation on Debian

----------------------



Special instructions for Debian have been contributed by Leonardo J. Caballero G.

You can access them via the `git hub repo file location `_.



Issues installation

-------------------



If on a Linux/Ubuntu/Debian machine you run into an error like::



    /var/lib/gems/1.9.1/gems/docsplit-0.7.2/lib/docsplit/image_extractor.rb:51:in `exists?': can't convert nil into String (TypeError)

    from /var/lib/gems/1.9.1/gems/docsplit-0.7.2/lib/docsplit/image_extractor.rb:51:in `ensure in convert'



This is because the ruby docsplit library is having an issue with the temp

folder accesses, and removal of temp files.   Just run the following command::



    sudo chmod 1777 /tmp && sudo chmod 1777 /var/tmp



And retry the conversion of your document



Development

===========



Normal flow: ::



    git clone [email protected]:collective/collective.documentviewer.git



    cd collective.documentviewer



    virtualenv .



    bin/pip install -r requirements.txt



    bin/buildout



Async Integration

-----------------



It it highly recommended to install and configure `collective.celery`_

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.



Settings

--------



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.

OCR

    Use ``tesseract`` to scan the document for text. This process can 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.

Auto layout file types

    Types that should automatically be converted to document viewer.



Dexterity support

-----------------



If you want to use it with your own Dexterity content type. You need to edit

the ``FTI`` in ``ZMI/portal_types/yourtype`` to add "documentviewer" in

the available view methods like this: ::



    

      

    



Also you need to set the primary field in the schema, for example: ::



    



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 delete 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.
