Converting PDFs to JPEG sequences using imagemagick

Imagemagick (available from all good package managers) has the ability to split a .pdf file into a set of numbered images via the following incantation…

convert -quality 100 -density 200 -colorspace sRGB <PathToPDF> -flatten <PathToOutputDirectory/>Page-%02d.jpeg
