Thanks for that. Can I ask another, related question ?

I also want thin lines to appear between two paragraphs at some points
in the document (so the line would be the width of a column). 

I'm using 'addFromList' based upon a list of paragraphs to build the
story and so I'm not sure how I can do this (I suppose I could make the
line an image but that seems a bit clunky). I can't, as far as I can
see, use absolute coordinates because I don't know where the paragraph
break is going to be rendered.

I'm sure there is a way - could anyone tell ?

thanks

Richard.
