A Plone product that provides the PDF viewer FlexPaper.

Project description


This package is a Plone product that will add a Page Turner view to the PDF File content type. The result is that you’ll be able to view PDFs much in the same way you can view them on It uses the open source project, Flex Paper, to display the PDFs. You can find information about it at


This product requires that you have pdf2swf installed. pdf2swf is included in older versions of SWFTools, up to 0.9.0 (the most recent version of SWFTools is 0.9.2 dating from 2012).

Installing pdf2swf with package managers

Where possible, we recommend you use package managers to install SWFTools as there are some dependencies that need to be installed.

If you’re using Ubuntu Lucid (10.04) (and possibly later versions, but not Trusty Tahr, 14.04):

# sudo apt-get install swftools

On Mac, if you have MacPorts installed you can,

# sudo port install swftools

On Debian, you’ll need to install from source as the swftools package does not include pdf2swf:

Checking that you have installed pdf2swf

Once you have installed the package, check if pdf2swf is in your path. On Linux:

# which pdf2swf

On Windows: make sure pdf2swf.exe is in your path:

C:> pdf2swf

If it isn’t in your path (ie. you get an error message above), you’ll have to install manually; see below.

Installing pdf2swf manually

If your package manager installs a version of SWFTools that does not include pdf2swf, you can install an older version of the package that does.

These instructions for installing on Ubuntu are based on

For AMD64:

# wget -P /tmp/ # chmod a+x /tmp/swftools_0.9.0-0ubuntu2_amd64.deb # sudo dpkg -i /tmp/swftools_0.9.0-0ubuntu2_amd64.deb

For i386:

# wget -P /tmp/ # chmod a+x /tmp/swftools_0.9.0-0ubuntu2_i386.deb # sudo dpkg -i /tmp/swftools_0.9.0-0ubuntu2_i386.deb

Other architectures are available at

If all else fails, you can download SWFTools from and install it yourself.


  • Add your PDF as a File to your Plone site (Add New -> File menu).

  • Edit the various setting of the Page turner by clicking the Page Turner Settings button.

  • To turn off auto-selecting of the page turner layout for PDF files, go to ZMI -> portal_properties -> site_properties and customize the page_turner_auto_select_layout property to off.

  • PDFs that were on your site before you activated this add-on will need to be converted (you will see an error message on each File until you convert it). To convert an individual PDF, click the Flexpaper Convert button. Large PDFs will take some time to be converted. To convert all PDFs on your site, go to your site’s URL and append /@@convertall-to-flexpaper, e.g.

Tested With

  • Plone 3 and 4

  • Also works with Blob storage transparently so the converted PDFs aren’t stored in the ZODB


Credit goes to Wildcard Corp and Talin Senner for sponsoring and designing the product, and Nathan Van Gheem for coding it.

Asynchronous Conversion

With large PDFs the conversion to Flex Paper can take some time. If you have installed and configured, this conversion will happen asynchronously.
