title: PDF reader as a running text / marquee
body: <p>for a neuroscientific project, 
  i would like to create 
  a program that reads a pdf file and presents it as a
  horizontally running text (marquee). </p>
  
  <p>As I am not an experienced programer, please tell me 
  how you would start and whether you see an easy way to realize this program.</p>
