Introduction

This package provides utilities to convert images and PDF files using ImageMagick. It also provides a generic /download.pdf browser view that allow your users to download Plone pages as PDF files with custom PDF cover, disclaimer and back cover (requires wkhtmltopdf system-package installed on your server).

Main features

Download Plone/Zope content as PDF files with custom PDF cover, table of contents, etc;
Provide utilities to extract PDF cover as image (using PyPDF2 and ImageMagick);
Provide utilities to extract metadata from PDF (using PyPDF2);
Provide utilities to update PDF metadata (using PyPDF2).

Installation

Make sure you have wkhtmltopdf 0.12.1+ installed or install it via zc.buildout
Make sure you have ImageMagick 6.3.7+ installed or install it via zc.buildout
Make sure you have an OS environment called EEACONVERTER_TEMP within your buildout if you have zope instances over more than one physical server.
Add eea.converter to your eggs section in your buildout and re-run buildout. You can download a sample buildout from https://github.com/collective/eea.converter/tree/master/buildouts/plone4

Getting started

Try http://localhost:8080/Plone/front-page/download.pdf

Customize output PDF

Cover

Provide custom browser:page called @@pdf.cover:

<browser:page
  for="my.package.interfaces.ICustomContent"
  name="pdf.cover"
  class=".app.pdfview.Cover"
  template="zpt/pdf.cover.pt"
  permission="zope2.View"
  />

Disclaimer

First page after PDF Cover containing author details and copyrights. Provide custom browser:page called @@pdf.cover:

<browser:page
  for="my.package.interfaces.ICustomContent"
  name="pdf.disclaimer"
  class=".app.pdfview.Disclaimer"
  template="zpt/pdf.disclaimer.pt"
  permission="zope2.View"
  />

Body

Provide custom browser:page called @@pdf.body:

<browser:page
  for="my.package.interfaces.ICustomContent"
  name="pdf.body"
  class=".app.pdfview.Body"
  template="zpt/pdf.body.pt"
  permission="zope2.View"
  />

Back Cover

Provide custom browser:page called @@pdf.cover.back:

<browser:page
  for="my.package.interfaces.ICustomContent"
  name="pdf.cover.back"
  class=".app.pdfview.BackCover"
  template="zpt/pdf.cover.back.pt"
  permission="zope2.View"
  />

To enable Table of contents provide an empty browser:page called @@pdf.toc:

<browser:page
  for="my.package.interfaces.ICustomContent"
  name="pdf.toc"
  template="zpt/pdf.toc.pt"
  permission="zope2.View"
  />

Options

For PDF cover you’ll have to provide a named adapter like:

<adapter
  name="pdf.cover"
  for=" my.package.interfaces.ICustomContent"
  provides="eea.converter.interfaces.IPDFOptionsMaker"
  factory=".adapters.CoverOptionsMaker" />

Same for PDF disclaimer:

<adapter
  name="pdf.disclaimer"
  for=" my.package.interfaces.ICustomContent"
  provides="eea.converter.interfaces.IPDFOptionsMaker"
  factory=".adapters.DisclaimerOptionsMaker" />

Or for PDF back cover:

<adapter
  name="pdf.cover.back"
  for=" my.package.interfaces.ICustomContent"
  provides="eea.converter.interfaces.IPDFOptionsMaker"
  factory=".adapters.BackCoverOptionsMaker" />

For PDF body you’ll have to provide a named adapter like:

<adapter
  name="pdf.body"
  for=" my.package.interfaces.ICustomContent"
  provides="eea.converter.interfaces.IPDFOptionsMaker"
  factory=".adapters.BodyOptionsMaker" />

For global PDF options provide an unamed adapter like:

<adapter
  for=" my.package.interfaces.ICustomContent"
  provides="eea.converter.interfaces.IPDFOptionsMaker"
  factory=".adapters.OptionsMaker" />

Also add custom print.css for your needs. See more at eea.pdf

Restrict access and async

In order to restrict access to /download.pdf you’ll have to provide a multi-adapter named pdf.support with a method called can_download like:

<browser:page
  name="pdf.support"
  for="zope.interface.Interface"
  class=".support.Support"
  permission="zope.Public"
  allowed_interface="eea.converter.interfaces.ISupport"
  />

Same for asynchronous download, define a method called async. See default implementation within eea.converter.browser.app.support or add an environment var called EEACONVERTER_ASYNC within your buildout.cfg:

[instance]
...
environment-vars =
  EEACONVERTER_ASYNC True

Content rules

This package uses Plone Content-rules to notify users by email when an asynchronous job is done. Thus 3 custom content-rules will be added within Plone > Site Setup > Content-rules

Export succeeded

Notify the person who requested a PDF/ePub export that the document successfully exported and provide a link to the downloadable file.

Export failed

Notify the person who requested a PDF/ePub export that the export failed.

Export failed (admin)

Notify admin that there were issues while exporting PDF/ePub

Content rules email string substitution

${download_came_from_url}

The absolute URL of the Plone object which is downloaded as PDF/ePub

${download_email}

Email address of the user that triggered the download as PDF/ePub action

${download_error}

Error traceback when download as PDF/ePub job fails

${download_from_email}

Site Admin email address customizable via Plone > Site Setup > Mail

${download_from_name}

Site Admin name customizable via Plone > Site Setup > Mail

${download_title}

Title of the Plone object which is downloaded as PDF/ePub

${download_url}

The absolute URL where the generated output PDF/ePub can be downloaded

${download_type}

Download type: PDF/ePub
