Hackpact 1: PDF imposition

Premise: I will write my own script(s) to impose pages from a source PDF:

The aim is to write a Python script to automate the process by iterating recursively over pages in a PDF. These will be called in Python as subprocesses using the subprocess module.

First, I'm working out which commands to use from the command line. The process should be as follows:

   #burst the source PDF, keep the name of the source plus page number (-%d)
   $ pdftk source.pdf burst output source-%d.pdf
   #resize the resulting burst single page PDF (this only does one - needs Python to iterate)
   $ magick mogrify -resize 50% new_source.pdf
   #or to resize to specific pixel dimensions such as 256x256
   $ magick mogrify -resize 256x256 new_source.pdf
   #impose 2up on a page using imagemagick montage command
   #assemble imposed PDFs into a single file
