This is the Objavi Renderer, which converts HTML files to PDF. It is a part of the Objavi publishing engine (github.com/sourcefabric/Objavi).
To create the PDF output from HTML pages Objavi Render uses the BookJS library (github.com/sourcefabric/BookJS) and the WebKit layout engine (www.webkit.org).
The Objavi Renderer is developed and maintained by Borko Jandras (firstname.lastname@example.org).

To compile the Renderer the Qt5 SDK is needed. For Ubuntu users this translates to having Qt5 development packages installed from the repository. Qt5 for Ubuntu is provided by the "Canonical Qt5 Edgers" team at:
Install the Qt5 packages by adding ppa:canonical-qt5-edgers/qt5-proper to the list of sources, then install the necessary packages, like this:
sudo add-apt-repository ppa:canonical-qt5-edgers/qt5-proper sudo apt-get install qtbase5-dev libqt5webkit5-dev sudo apt-get install qtdeclarative5-dev qtlocation5-dev qtsensors5-dev
Some Qt5 developmet packages are missing some dependancies, so if you get link errors make sure you have the following packages installed as well:
sudo apt-get install libxml2-dev libxslt1-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev
To compile the Renderer binary go to the source directory and issue the following commands:
QT_SELECT=qt5 qmake make
The Renderer can be run in two modes: normal and the GUI mode.
The GUI mode displays a window that looks and behaves just like a normal web browser would. This mode is intended for BookJS developers to test how BookJS behaves inside the WebKit engine. To do this you can select the "Install BookJS" button inside the Tools menu. You can also fire up the standard WebKit developer console and experiment. To start the Renderer in the GUI mode use the "-gui" command line option.
The normal mode, also called the offline mode, is intended to convert web pages to PDFs from the command line. To run the Renderer in this mode specify the URL of the web page you want to convert to PDF as the command line argument. Other command line options are:
- -bookjs -- specifies the location of the BookJS code to use for formatting the page
- -custom-css -- specifies the CSS text to append after all other CSS text
- -output -- specified the output file where the PDF should be written to
- -page-config -- BookJS page configuration (see below)
- -print-timeout -- number of seconds to wait for the page to be ready for printing
The BookJS page configuration is specified in the following form:
