Convert DZSlides presentation to PDF
Given you have created and given a presentation based on DZSlides (maybe powered by AsciiDoctor & Gradle 
), you might have the need to publish it at one point.
One of the most compatible way is to put the slides into a PDF, but that might not be as much obvious as you might expect. Here is one approach:
* Convert the slides to png files using the slides2png script:
groovy ./dzslides/scripts/slides2png file:///Users/markus/Documents/20151001_Presentation/slides/src/slides.html
As the script it uses GEB to utilize the browser and take screnshots from your slides, it requires a fully qualified URL to find your presentation. In this case, it resides on the filesystem, so it starts with file:// – you could also fire up a minimal HTTP server (python -m SimpleHTTPServer , anyone? ) to shorten the URL.
* The results are safed in /tmp/geb-reports by default, including a presentation.pdf file that is the desired PDF. Voilà 
Have fun!
