When developing PDFs using Prawn, I usually write a script that regenerates the PDF and writes it to file on a loop. I then open the PDF in Chrome, and as I make changes to the PDF I will go to Chrome and refresh the page, just as I would if I was developing a webpage.
This only works great if I am working on a single page PDF, because unlike a webpage, Chrome does not remember the zoom or scroll position between refreshes so I need to zoom out and scroll down in order to see anything beyond the first page.
Has anyone figured out a better workflow for developing more complex PDFs where you can tweak the code and preview the change almost immediately?
Thanks,
