I hate to break the news to you: The Igor Pro Carbon doen't (yet) 
support output to pdf. You can of course _print_ to pdf, but that produces 
a whole page, with the figure on it. As far as encapsulated postscript is 
concerned: epstopdf usually does it for me, but yes: Acrobat's display of 
line-art is horrible.

I know there are several code samples floating about showing how to produce 
full-screen display on X. If only Apple's pdf-routines could use hyperlinks...

But if the aim is just to have a run-through, a one-liner should work.

Take care,
