But I'm not talking about illustrations, I'm talking about equations. I typeset mine with LaTex, and output to PDF. I didn't think they were being displayed as graphics in the resulting PDF file, though I suppose they could be. I guess I was basing my assumptions on what I know about postscript code. Does PDF not have typesetting structures, then? (I guess I could try saving a PDF file with equations out as some other kind of text and see what I get.)
